INTRODUCTION SS-14 HANDLING PRECAUTIONS ON RELATED COMPONENTS 1. BRAKE SYSTEM The brake system is one of the most important safety components. Always follow the directions and notes given in section BR of the repair manual for the relevant model year when handling brake system parts. NOTICE: When repairing the brake master cylinder or TRAC system, bleed the air out of the TRAC system. 2. DRIVE TRAIN AND CHASSIS The drive train and chassis are components that can have great effects on the running performance and vibration resistance of the vehicle. After installing components in the sections listed in the table below, perform alignments to ensure correct mounting angles and dimensions. Particularly accurate repair of the body must also be done to ensure correct alignment. HINT: Correct procedures and special tools are required for alignment. Always follow the directions given in the repair manual for the relevant model during alignment and section DI of this manual. Component to be aligned 3. Section of repair manual for relevant model Front Wheels Suspension and Axle (SA) section Rear Wheels Suspension and Axle (SA) section COMPONENTS ADJACENT TO THE BODY PANELS Various types of component parts are mounted directly on or adjacently to the body panels. Strictly observe the following precautions to prevent damaging these components and the body panels during handling.  Before repairing the body panels, remove their components or apply protective covers over the components.  Before prying components off using a screwdriver or a scraper, etc., attach protective tape to the tool tip or blade to prevent damaging the components and the body paint.  Before removing components from the outer surface of the body, attach protective tape to the body to ensure no damage to painted areas. HINT: Apply touch-up paint to any damaged paint surfaces.  Before drilling or cutting sections, make sure that there are no wires, etc. on the reverse side. 4. ECU (ELECTRONIC CONTROL UNIT) Many ECUs are mounted in this vehicle. Take the following precautions during body repair to prevent damage to the ECUs.  Before starting electric welding operations, disconnect the negative (-) terminal cable from the battery. When the negative (-) terminal cable is disconnected from the battery, memory of the clock and audio systems will be cancelled. So before starting work, make a record of the contents memorized by each memory system. Then when work is finished, reset the clock and audio systems as before. When the vehicle has tilt and telescopic steering, power seat and outside rear view mirror, which are all equipped with memory function, it is not possible to make a record of the memory contents. So when the operation is finished, it will be necessary to explain this fact to the customer, and request the customer to adjust the features and reset the memory.  Do not expose the ECUs to ambient temperatures above 80°C (176°F). NOTICE: If it is possible the ambient temperature may reach 80°C (176°F) or more, remove the ECUs from the vehicle before starting work.  Be careful not to drop the ECUs and not to apply physical shocks to them. INTRODUCTION SS-5 HOW TO USE THIS MANUAL 1.

F10005A INTRODUCTION SS-15 PRECAUTIONS FOR REPAIRING BODY STRUCTURE PANELS 1. HEAT REPAIR FOR BODY STRUCTURE PANELS Toyota prohibits the use of the heat repair method on body structure panels when repairing a vehicle damaged in a collision. Panels that have high strength and rigidity, as well as a long life span for the automobile body are being sought after. At Toyota, in order to fulfill these requirement, we use high tensile strength steel sheets and rust preventive steel sheets on the body. High tensile steel sheets are made with alloy additives and a special heat treatment in order to improve the strength. To prevent the occurrence of rust for a long period of time, the surface of the steel is coated with a zinc alloy. If a body structure parts are heat repaired with an acetylene torch or other heating source, the crystalline organization of the steel sheet will change and the strength of the steel sheet will be reduced. The ability of the body to resist rust is significantly lowered as well since the rust resistant zinc coating is destroyed by heat and the steel sheet surface is oxidized. 2. STRUCTURE PANEL KINKS A sharp deformation angle on the panel that cannot be returned to its original shape by pulling or hammering is called a kink. Since structure parts were designed to exhibit a 100% performance when they were in their original shape, if they are deformed in an accident, or if the deformed parts are repaired and reused, they become unable to exhibit the same performance as intended in the design. It is necessary to replace the part where the kink has occurred. SS-16 INTRODUCTION 3. IMPACT BEAM REPAIR The impact beam and bracket are necessary and important parts in maintaining a survival space for passengers in a side collision. For impact beam, we use special high tensile strength steel. The high tensile strength steel maintains its special crystalline organization by heat treatment or alloy additives. Since these parts were designed to exhibit a 100% performance when they were in their original shape, if they are deformed in an accident, or if the deformed parts are repaired and reused, they become unable to exhibit the same performance as intended in the design. It is necessary to replace the door assembly when impact beam or bracket is damaged. INTRODUCTION SS-9 PROPER AND EFFICIENT WORK PROCEDURES 1. REMOVAL (a) PRE-REMOV AL MEASURING (1) Before removal or cutting operations, take measurements in accordance with the dimension diagram. Always use a puller to straighten a damaged body or frame. F10007 (b) CUTTING AREA Cutting Okay Reinforcement (1) Always cut in a straight line and avoid reinforced area. Corners F10008A (c) PRECAUTIONS FOR DRILLING OR CUTTING (1) Check behind any area to be drilled or cut to insure that there are no hoses, wires, etc., that may be damaged. HINT: See ”Handling Precautions on Related Components” on page SS-14 . WRONG F10009A (d) REMOVAL OF ADJACENT COMPONENTS (1) When removing adjacent components, apply protective tape to the surrounding body and your tools to prevent damage. HINT: See ”Handling Precautions on Related Components” on page SS-14 . F10010 INTRODUCTION SS-10 2. PREPARATION FOR INSTALLATION (a) SPOT WELD POINTS (1) When welding panels with a combined thickness of over 3 mm (0.12 in.), use a MIG (Metal Inert Gas) welder for plug welding. HINT: Spot welding will not provide sufficient durability for panels over 3 mm (0.12 in.) thick. Less than 3mm F10011A (b) APPLICATION OF WELD-THROUGH PRIMER (SPOT SEALER) (1) Remove the paint from the portion of the new parts and body to be welded, and apply weld-through primer. F10012 (c) MAKING HOLES FOR PLUG WELDING (1) For areas where a spot welder cannot be used, use a puncher or drill to make holes for plug welding. REFERENCE: mm (in.) Puncher Thickness of welded portion Size of plug hole 1.0 (0.04) under 5 (0.20) φ over 1.0 (0.04) - 1.5 (0.06) 6.4 (0.26) φ over 1.5 (0.06) over 8 (0.31) φ over F10013A (d) SAFETY PRECAUTIONS FOR ELECTRICAL COMPONENTS (1) When welding, there is a danger that electrical components will be damaged by the electrical current flowing through the body. (2) Before starting work, disconnect the negative terminal of the battery and ground the welder near the welding location of the body. F10014 (e) ROUGH CUTTING OF JOINTS Air Saw 20~30mm Overlap F10015A (1) For joint areas, rough cut the new parts, leaving 20 30 mm (0.79 - 1.18 in.) overlap. INTRODUCTION 3. SS-11 INSTALLATION (a) PRE-WELDING MEASUREMENTS (1) Always take measurements before installing underbody or engine components to insure correct assembly. After installation, confirm proper fit. Body Measurement Diagrams F10016A (b) WELDING PRECAUTIONS (1) The number of welding spots should be as follows. Spot weld: 1.3 X No. of manufacturer’s spots. Plug weld: More than No. of manufacturer’s plugs. (2) Plug welding should be done with a MIG (Metal Inert Gas) welder. Do not gas weld or braze panels at areas other than specified. WRONG F10017A (c) POST-WELDING REFINISHING (1) Always check the welded spots to insure they are secure. (2) When smoothing out the weld spots with a disc grinder, be careful not to grind off too much as this would weaken the weld. OKAY WRONG F10018A (d) SPOT WELD LOCATIONS (1) Try to avoid welding over previous spots. Tip Cutter F10019A (e) SPOT WELDING PRECAUTIONS Old Spot Locations New Spot Locations (1) The shape of the welding tip point has an effect on the strength of the weld. (2) Always insure that the seams and welding tip are free of paint. F10020A INTRODUCTION SS-12 4. Sealer Gun ANTI-RUST TREATMENT (a) BODY SEALER APPLICATION (1) For water-proofing and anti-corrosion measures, always apply the body sealer to the body panel seams and hems of the doors, hoods, etc. F10021A (b) UNDERCOAT APPLICATION (1) To prevent corrosion and protect the body from damage by flying stones, always apply sufficient undercoat to the bottom surface of the under body and inside of the wheel housings. F10022 5. ANTI-RUST TREATMENT AFTER PAINTING PROCESS (a) ANTI-RUST AGENT (WAX) APPLICATION (2) To preserve impossible to paint areas from corrosion, always apply sufficient anti-rust agent (wax) to the inside of the hemming areas of the doors and hoods, and around the hinges, or the welded surfaces inside the boxed cross-section structure of the side member, body pillar, etc. F10023 INTRODUCTION 6.

SS-14 INTRODUCTION HANDLING PRECAUTIONS ON RELATED COMPONENTS 1. BRAKE SYSTEM The brake system is one of the most important safety components. Always follow the directions and notes given in section BR of the repair manual for the relevant model year when handling brake system parts. NOTICE: When repairing the brake master cylinder or TRAC system, bleed the air out of the TRAC system. 2. DRIVE TRAIN AND CHASSIS The drive train and chassis are components that can have great effects on the running performance and vibration resistance of the vehicle. After installing components in the sections listed in the table below, perform alignments to ensure correct mounting angles and dimensions. Particularly accurate repair of the body must also be done to ensure correct alignment. HINT: Correct procedures and special tools are required for alignment. Always follow the directions given in the repair manual for the relevant model during alignment and section DI of this manual. 3. Component to be aligned Section of repair manual for relevant model Front Wheels Suspension and Axle (SA) section Rear Wheels Suspension and Axle (SA) section COMPONENTS ADJACENT TO THE BODY PANELS Various types of component parts are mounted directly on or adjacently to the body panels. Strictly observe the following precautions to prevent damaging these components and the body panels during handling.  Before repairing the body panels, remove their components or apply protective covers over the components.  Before prying components off using a screwdriver or a scraper, etc., attach protective tape to the tool tip or blade to prevent damaging the components and the body paint.  Before removing components from the outer surface of the body, attach protective tape to the body to ensure no damage to painted areas. HINT: Apply touch-up paint to any damaged paint surfaces.  Before drilling or cutting sections, make sure that there are no wires, etc. on the reverse side. 4. ECU (ELECTRONIC CONTROL UNIT) Many ECUs are mounted in this vehicle. Take the following precautions during body repair to prevent damage to the ECUs.  Before starting electric welding operations, disconnect the negative (-) terminal cable from the battery. When the negative (-) terminal cable is disconnected from the battery, memory of the clock and audio systems will be cancelled. So before starting work, make a record of the contents memorized by each memory system. Then when work is finished, reset the clock and audio systems as before. When the vehicle has tilt and telescopic steering, power seat and outside rear view mirror, which are all equipped with memory function, it is not possible to make a record of the memory contents. So when the operation is finished, it will be necessary to explain this fact to the customer, and request the customer to adjust the features and reset the memory.  Do not expose the ECUs to ambient temperatures above 80C (176F). NOTICE: If it is possible the ambient temperature may reach 80C (176F) or more, remove the ECUs from the vehicle before starting work.  Be careful not to drop the ECUs and not to apply physical shocks to them. INTRODUCTION SS-5 HOW TO USE THIS MANUAL 1. BODY PANEL REPLACEMENT THIS MANUAL F10113 SS-6 INTRODUCTION F10114A INTRODUCTION 2. SS-7 SYMBOLS The following symbols are used in the welding diagrams in section BP of this manual to indicate cutting areas and the types of weld required. F10005A SS-8 INTRODUCTION 3. ILLUSTRATION OF WELD POINT SYMBOLS EXAMPLE: F10005A INTRODUCTION SS-15 PRECAUTIONS FOR REPAIRING BODY STRUCTURE PANELS 1. HEAT REPAIR FOR BODY STRUCTURE PANELS Toyota prohibits the use of the heat repair method on body structure panels when repairing a vehicle damaged in a collision. Panels that have high strength and rigidity, as well as a long life span for the automobile body are being sought after. At Toyota, in order to fulfill these requirement, we use high tensile strength steel sheets and rust preventive steel sheets on the body. High tensile steel sheets are made with alloy additives and a special heat treatment in order to improve the strength. To prevent the occurrence of rust for a long period of time, the surface of the steel is coated with a zinc alloy. If a body structure parts are heat repaired with an acetylene torch or other heating source, the crystalline organization of the steel sheet will change and the strength of the steel sheet will be reduced. The ability of the body to resist rust is significantly lowered as well since the rust resistant zinc coating is destroyed by heat and the steel sheet surface is oxidized. 2. STRUCTURE PANEL KINKS A sharp deformation angle on the panel that cannot be returned to its original shape by pulling or hammering is called a kink. Since structure parts were designed to exhibit a 100% performance when they were in their original shape, if they are deformed in an accident, or if the deformed parts are repaired and reused, they become unable to exhibit the same performance as intended in the design. It is necessary to replace the part where the kink has occurred. SS-16 INTRODUCTION 3. IMPACT BEAM REPAIR The impact beam and bracket are necessary and important parts in maintaining a survival space for passengers in a side collision. For impact beam, we use special high tensile strength steel. The high tensile strength steel maintains its special crystalline organization by heat treatment or alloy additives. Since these parts were designed to exhibit a 100% performance when they were in their original shape, if they are deformed in an accident, or if the deformed parts are repaired and reused, they become unable to exhibit the same performance as intended in the design. It is necessary to replace the door assembly when impact beam or bracket is damaged. INTRODUCTION SS-9 PROPER AND EFFICIENT WORK PROCEDURES 1. REMOVAL (a) PRE-REMOVAL MEASURING (1) Before removal or cutting operations, take measurements in accordance with the dimension diagram. Always use a puller to straighten a damaged body or frame. F10007 (b) CUTTING AREA (1) Always cut in a straight line and avoid reinforced area. F10008A (c) PRECAUTIONS FOR DRILLING OR CUTTING (1) Check behind any area to be drilled or cut to insure that there are no hoses, wires, etc., that may be damaged. HINT: See “Handling Precautions on Related Components” on page SS-14. F10009A (d) REMOVAL OF ADJACENT COMPONENTS (1) When removing adjacent components, apply protective tape to the surrounding body and your tools to prevent damage. HINT: See “Handling Precautions on Related Components” on page SS-14. F10010 SS-10 INTRODUCTION 2. PREPARATION FOR INSTALLATION (a) SPOT WELD POINTS (1) When welding panels with a combined thickness of over 3 mm (0.12 in.), use a MIG (Metal Inert Gas) welder for plug welding. HINT: Spot welding will not provide sufficient durability for panels over 3 mm (0.12 in.) thick. F10011A (b) APPLICATION OF WELD-THROUGH PRIMER (SPOT SEALER) (1) Remove the paint from the portion of the new parts and body to be welded, and apply weld-through primer. F10012 (c) MAKING HOLES FOR PLUG WELDING (1) For areas where a spot welder cannot be used, use a puncher or drill to make holes for plug welding. REFERENCE: mm (in.) Thickness of welded portion Size of plug hole 1.0 (0.04) under 5 (0.20) ø over 1.0 (0.04) - 1.5 (0.06) 6.4 (0.26) ø over 1.5 (0.06) over 8 (0.31) ø over F10013A (d) SAFETY PRECAUTIONS FOR ELECTRICAL COMPONENTS (1) When welding, there is a danger that electrical components will be damaged by the electrical current flowing through the body. (2) Before starting work, disconnect the negative terminal of the battery and ground the welder near the welding location of the body. F10014 (e) ROUGH CUTTING OF JOINTS (1) For joint areas, rough cut the new parts, leaving 20 - 30 mm (0.79 - 1.18 in.) overlap. F10015A INTRODUCTION 3. SS-11 INSTALLATION (a) PRE-WELDING MEASUREMENTS (1) Always take measurements before installing underbody or engine components to insure correct assembly. After installation, confirm proper fit. F10016A (b) WELDING PRECAUTIONS (1) The number of welding spots should be as follows. Spot weld: 1.3 X No. of manufacturer’s spots. Plug weld: More than No. of manufacturer’s plugs. (2) Plug welding should be done with a MIG (Metal Inert Gas) welder. Do not gas weld or braze panels at areas other than specified. F10017A (c) POST-WELDING REFINISHING (1) Always check the welded spots to insure they are secure. (2) When smoothing out the weld spots with a disc grinder, be careful not to grind off too much as this would weaken the weld. F10018A (d) SPOT WELD LOCATIONS (1) Try to avoid welding over previous spots. F10019A (e) SPOT WELDING PRECAUTIONS (1) The shape of the welding tip point has an effect on the strength of the weld. (2) Always insure that the seams and welding tip are free of paint. F10020A SS-12 INTRODUCTION 4. ANTI-RUST TREATMENT (a) BODY SEALER APPLICATION (1) For water-proofing and anti-corrosion measures, always apply the body sealer to the body panel seams and hems of the doors, hoods, etc. F10021A (b) UNDERCOAT APPLICATION (1) To prevent corrosion and protect the body from damage by flying stones, always apply sufficient undercoat to the bottom surface of the under body and inside of the wheel housings. F10022 5. ANTI-RUST TREATMENT AFTER PAINTING PROCESS (a) ANTI-RUST AGENT (WAX) APPLICATION (2) To preserve impossible to paint areas from corrosion, always apply sufficient anti-rust agent (wax) to the inside of the hemming areas of the doors and hoods, and around the hinges, or the welded surfaces inside the boxed cross-section structure of the side member, body pillar, etc. F10023 INTRODUCTION 6.

wiring attaches to the Body, thereby providing a return path for an electrical circuit; without a ground, current cannot flow. BATTERY Stores chemical energy and converts it into electrical energy. Provides DC current for the auto’s various electrical circuits. CAPACITOR (Condenser) A small holding unit for temporary storage of electrical voltage. CIGARETTE LIGHTER An electric resistance heating element. HEADLIGHTS Current flow causes a headlight 1. SINGLE filament to heat up and emit light. A FILAMENT headlight may have either a single (1) filament or a double (2) filament 2. DOUBLE FILAMENT CIRCUIT BREAKER Basically a reusable fuse, a circuit breaker will heat and open if too much current flows through it. Some units automatically reset when cool, others must be manually reset. HORN An electric device which sounds a loud audible signal. DIODE A semiconductor which allows current flow in only one direction. IGNITION COIL Converts low-voltage DC current into high-voltage ignition current for firing the spark plugs. DIODE, ZENER LIGHT Current flow through a filament causes the filament to heat up and emit light. A diode which allows current flow in one direction but blocks reverse flow only up to a specific voltage. Above that potential, it passes the excess voltage. This acts as a simple voltage regulator. PHOTODIODE The photodiode is a semiconductor which controls the current flow according to the amount of light. LED (LIGHT EMITTING DIODE) Upon current flow, these diodes emit light without producing the heat of a comparable light. DISTRIBUTOR, IIA Channels high-voltage current from the ignition coil to the individual spark plugs. METER, ANALOG Current flow activates a magnetic coil which causes a needle to move, thereby providing a relative display against a background calibration. FUSE METER, DIGITAL Current flow activates one or many LED’s, LCD’s, or fluorescent displays, which provide a relative or digital display. A thin metal strip which burns through when too much current flows through it, thereby stopping current flow and protecting a circuit from damage. FUEL FUSIBLE LINK (for Medium Current Fuse) (for High Current Fuse or Fusible Link) A heavy-gauge wire placed in high amperage circuits which burns through on overloads, thereby protecting the circuit. The numbers indicate the crosssection surface area of the wires. M 2001 AVALON (EWD431U) 18 MOTOR A power unit which converts electrical energy into mechanical energy, especially rotary motion. E RELAY Basically, an electrically operated 1. NORMALLY switch which may be normally CLOSED closed (1) or open (2). Current flow through a small coil creates a magnetic field which either opens or closes an attached switch. SPEAKER An electromechanical device which creates sound waves from current flow. 2. NORMALLY OPEN SWITCH, MANUAL 1. NORMALLY OPEN RELAY, DOUBLE THROW A relay which passes current through one set of contacts or the other. Opens and closes circuits, i it thereby th b stopping (1) or allowing (2) current flow. 2. NORMALLY CLOSED RESISTOR An electrical component with a fixed resistance, placed in a circuit to reduce voltage to a specific value. SWITCH, DOUBLE THROW A switch which continuously passes current through one set of contacts or the other. RESISTOR, TAPPED A resistor which supplies two or more different non adjustable resistance values. SWITCH, IGNITION A key operated switch with several positions which allows various circuits, particularly the primary ignition circuit, to become operational. RESISTOR, VARIABLE or RHEOSTAT A controllable resistor with a variable rate of resistance. Also called a potentiometer or rheostat. SENSOR (Thermistor) A resistor which varies its resistance with temperature. SWITCH, WIPER PARK Automatically returns wipers to the stop position when the wiper switch is turned off. SENSOR, SPEED Uses magnetic impulses to open and close a switch to create a signal for activation of other components. TRANSISTOR A solidstate device typically used as an electronic relay; stops or passes current depending on the voltage applied at ”base”. (Reed Switch Type) SHORT PIN Used to provide an unbroken connection within a junction block. SOLENOID An electromagnetic coil which forms a magnetic field when current flows, to move a plunger, etc. WIRES Wires are always drawn as (1) NOT straight lines on wiring CONNECTED diagrams. Crossed wires (1) without a black dot at the junction are j nott joined; j i d crossed wires (2) with a black dot or octagonal ( ) (2) SPLICED mark at the junction are spliced (joined) connections. 2001 AVALON (EWD431U) 19 I GROUND POINT ENGINE CONTROL MODULE BR (E1) BR IDLE AIR CONTROL VALVE A BR A A BR 10 II2 BR B B BR B BR W- B HEADLIGHT LOW RH 11 IJ1 W- B IGNITION COIL AND IGNITER NO. 2 W- B IGNITION COIL AND IGNITER NO. 3 W- B IGNITION COIL AND IGNITER NO. 4 W- B IGNITION COIL AND IGNITER NO. 5 W- B IGNITION COIL AND IGNITER NO. 6 W- B MULTI DISPLAY (GND1) W- B 7 4G LUGGAGE COMPARTMENT DOOR OPENER SW W- B 7 4H W- B 20 4H W- B 20 4A W- B 7 4A W- B 20 4B W- B BR (E02) (E05) W- B ENGINE CONTROL MODULE (E03) W- B BR I22 W- B E4 W- B (CG) BLOWER RESISTOR HEATER CONTROL SW FRONT TURN SIGNAL LIGHT AND PARKING LIGHT RH POWER OUTLET W- B A I13 W- B A A (MANUAL A/C) W- B A W- B A W- B ABS & BA & TRAC & VSC ECU BK/UP LP RELAY J9 JUNCTION CONNECTOR W- B I16 TURN SIGNAL FLASHER RELAY POWER OUTLET MAIN SW 21 3B 8 3B W- B A W- B 7 3A 20 3B W- B 20 3A W- B 7 3B W- B 7 3G W- B 20 3G W- B A W- B W- B W- B A IJ 21 3A A CRUISE CONTROL ECU (ECC) COMBINATION SW (ESS) COMBINATION SW (EP) COMBINATION METER RHEOSTAT W- B W- B I25 8 IC1 W- B W- B W- B W- B W- B 11 EA1 W- B R- L (*9) (- ) COMBINATION METER 2 DRL NO. 3 RELAY 2 DRL NO. 4 RELAY W- B FRONT FOG LIGHT RH (GND2) 6 W- B W- B A A FRONT WIPER MOTOR WIRELESS DOOR LOCK BUZZER W- B (COLUMN SHIFT) A/C BLOWER MOTOR LINEAR CONTROLLER W- B 8 3A 7 4B W- B (MANUAL A/C) CRUISE CONTROL ACTUATOR THEFT DETERRENT BUZZER W- B I15 (MANUAL A/C) W- B I14 W- B W- B W- B O/D MAIN SW W- B (E04) 9 II1 W- B J5 JUNCTION CONNECTOR THEFT DETERRENT ECU W- B I22 EC W- B GLOVE BOX LIGHT SW (EXCEPT CANADA) EA 2001 AVALON (EWD431U) 282 (E01) W- B EB DATA LINK CONNECTOR 3 (E0M) W- B I23 HEATED OXYGEN SENSOR (BANK 1 SENSOR 2) (SG) W- B BR (ET) IGNITION COIL AND IGNITER NO. 1 HEADLIGHT LOW RH BR (CANADA) MULTI DISPLAY DATA LINK CONNECTOR 3 21 IK2 B BR J5 JUNCTION CONNECTOR J7 JUNCTION A CONNECTOR W- B DATA LINK CONNECTOR 1 A ABS ACTUATOR AND ECU W- B (GND1) (* 4) ABS SOL RELAY 10 2F W- B 3 (* 3) 8 2D W- B 5 2D W- B 3 1 EC1 FAN NO. 2 RELAY W- B WATER TEMP.

MEMO 2001 AVALON (EWD431U) 289 HOW TO USE THIS MANUAL B This manual provides information on the electrical circuits installed on vehicles by dividing them into a circuit for each system. The actual wiring of each system circuit is shown from the point where the power source is received from the battery as far as each ground point. (All circuit diagrams are shown with the switches in the OFF position.) When troubleshooting any problem, first understand the operation of the circuit where the problem was detected (see System Circuit section), the power source supplying power to that circuit (see Power Source section), and the ground points (see Ground Point section). See the System Outline to understand the circuit operation. When the circuit operation is understood, begin troubleshooting of the problem circuit to isolate the cause. Use Relay Location and Electrical Wiring Routing sections to find each part, junction block and wiring harness connectors, wiring harness and wiring harness connectors, splice points, and ground points of each system circuit. Internal wiring for each junction block is also provided for better understanding of connection within a junction block. Wiring related to each system is indicated in each system circuit by arrows (from__, to__). When overall connections are required, see the Overall Electrical Wiring Diagram at the end of this manual. 2001 AVALON (EWD431U) 3 B HOW TO USE THIS MANUAL ∗ The system shown here is an EXAMPLE ONLY.

[N] : Page No. 2001 AVALON (EWD431U) 5 B HOW TO USE THIS MANUAL [O] SYSTEM OUTLINE Current is applied at all times through the STOP fuse to TERMINAL 2 of the stop light SW. When the ignition SW is turned on, current flows from the GAUGE fuse to TERMINAL 8 of the light failure sensor, and also flows through the rear lights warning light to TERMINAL 4 of the light failure sensor. STOP LIGHT DISCONNECTION WARNING When the ignition SW is turned on and the brake pedal is pressed (Stop light SW on), if the stop light circuit is open, the current flowing from TERMINAL 7 of the light failure sensor to TERMINALS 1, 2 changes, so the light failure sensor detects the disconnection and the warning circuit of the light failure sensor is activated. As a result, the current flows from TERMINAL 4 of the light failure sensor to TERMINAL 11 to GROUND and turns the rear lights warning light on. By pressing the brake pedal, the current flowing to TERMINAL 8 of the light failure sensor keeps the warning circuit on and holds the warning light on until the ignition SW is turned off.

An outline of the engine control is explained here. 1. INPUT SIGNALS (1) Engine coolant temp. signal circuit The engine coolant temp. sensor detects the engine coolant temp. and has a built-in thermistor with a resistance which varies according to the water temp. is input into TERMINAL THW of the engine control module as a control signal. (2) Intake air temp. signal circuit The intake air temp. sensor is installed in the mass air flow meter and detects the intake air temp., which is input as a control signal into TERMINAL THA of the engine control module. (3) RPM signal system Camshaft position and crankshaft position are detected by the camshaft position sensor and crankshaft position sensor. The camshaft position is input as a control signal to TERMINAL VV2+ of the engine control module, and the engine RPM is input into TERMINAL NE+. (4) Throttle signal circuit The throttle position sensor detects the throttle valve opening angle as a control signal, which is input into TERMINAL VTA1 of the engine control module. (5) Vehicle speed signal system The vehicle speed sensor, installed inside the transmission, detects the vehicle speed and inputs a control signal into TERMINAL SPD of the engine control module. (6) Park/Neutral position SW signal system The Park/Neutral position SW detects whether the shift position is in neutral, parking or not, and inputs a control signal into TERMINAL STA of the engine control module. (7) A/C SW signal system The A/C amplifier inputs the A/C operations into TERMINAL A/C of the engine control module as a control signal. (8) Battery signal circuit Voltage is always supplies to TERMINAL BATT of the engine control module. If you turn on the ignition SW, the current goes from TERMINAL MREL of the engine control module to the EFI relay and put on the relay, and the voltage related to the engine control module operation is supplied to TERMINAL +B of the engine control module through the EFI relay. (9) Intake air volume signal circuit Intake air volume is detected by the mass air flow meter and a signal is input into TERMINAL VG of the engine control module as a control signal. (10) NSW signal circuit To confirm whether the engine is cranking, the voltage applied to the starter motor during cranking is detected and the signal is input into TERMINAL NSW of the engine control module as a control signal. (11) Engine knock signal circuit Engine knocking is detected by the knock sensor 1 and 2, then the signals are input into TERMINALS KNKR and KNKL of the engine control module as a control signal. (12) Air fuel ratio signal system The air fuel ratio is detected and input as a control signal into TERMINALS AFL+, AFR+ of the engine control module. 2001 AVALON (EWD431U) 88 2. CONTROL SYSTEM ∗ SFI (Sequential multiport Fuel Injection) system The SFI system monitors the engine condition through the signals, which are input from each sensor (Input signals (1) to (12) ). The best fuel injection volume is decided based on this data and the program memorized by the engine control module, and the control signal is output to TERMINALS #10, #20, #30, #40, #50 and #60 of the engine control module to operate the injector (Inject the fuel). The SFI system produces control of fuel injection operation by the engine control module in response to the driving conditions. ∗ ESA (Electronic Spark Advance) system The ESA system monitors the engine condition through the signals, which are input to the engine control module from each sensor (Input signals from 1, 3, 11). The best ignition timing is decided according to this data and the memorized data in the engine control module and the control signal is output to TERMINALS IGT1, IGT2, IGT3, IGT4, IGT5 and IGT6. This signal controls the igniter to provide the best ignition timing for the driving conditions. ∗ Idle air control system The idle air control system (Rotary solenoid type) increases the rpm and provides idle stability for fast idle-up when the engine is cold, and when the idle speed has dropped due to electrical load and so on, the engine control module evaluates the signals from each sensor (Input signals from 1, 3, 4, 7, 8), current is output to TERMINAL RSO to control idle air control valve. ∗ ACIS (Acoustic Control Induction System) ACIS includes a valve in the bulkhead separating the surge tank into two parts. This valve is opened and closed in accordance with the driving conditions to control the intake manifold length in two stages for increased engine output in all ranges from low to high speeds. The engine control module judges the engine speed by the signals ( (3), (4) ) from each sensor and outputs signals to the TERMINALS ACIS and ACI1 to control the VSV (ACIS No.1 or No.2). 3. DIAGNOSIS SYSTEM With the diagnosis system, when there is a malfunction in the engine control module signal system, the malfunctioning system is recorded in the memory. 4. FAIL-SAFE SYSTEM When a malfunction occurs in any systems, if there is a possibility of engine trouble being caused by continued control based on the signals from that system, the fail-safe system either controls the system by using data (Standard values) recorded in the engine control module memory or else stops the engine. 2001 AVALON (EWD431U) 89 ENGINE CONTROL SERVICE HINTS C/OPN RELAY 3-5

In such a case, this system automatically controls the engine output and the braking to each wheel, to decrease the extreme over steering and under steering. ∗ To decrease extreme over steering tendency When the system determines that the over steering tendency is large, the system applies brakes to the outer wheels according to the degree of over steering, and creates a moment towards the outer side of the vehicle, to decrease the tendency of over steering. Also, when the brakes are applied, the vehicle speed decreases while the stability increases. ∗ To decrease extreme under steering tendency When the system determines that the under steering tendency is large, the system applies brakes to the front or rear wheels according to the degree of under steering, to decrease the tendency of under steering. ∗ VSC OFF SW The SW to send the VSC system into OFF mode. When the SW is pushed after starting the engine, the system will be in OFF mode, and the VSC off indicator light will turn on. When the SW is pushed again, the system will be in standby mode. When the engine is stopped and re-started, regardless of the VSC OFF SW, the system will be in standby mode. Information to the driver The VSC system informs the driver when the tire grip is about to exceed its grip capacity, by blinking the slip indicator light and turning on the buzzer. Accordingly, the driver is informed to drive more gently.

SOURCE SYSTEM (SEE PAGE 72) * 1 : FLOOR SHIFT * 2 : COLUMN SHIFT R- L FROM POWER SOURCE SYSTEM (SEE PAGE 72) SYSTEM OUTLINE ABS is a brake system designed for the purpose to improve the operating ability securing the stability of the vehicle by preventing the locking-up of the vehicle controlling the wheel cylinder pressure of all the four wheels at the time of sudden braking. 1. INPUT SIGNALS (1) Speed sensor signal The speed of the wheels is detected and input to TERMINALS FL+, FR+, RL+, and RR+ of the ABS actuator and ECU. (2) Stop light SW signal A signal is input to TERMINAL STP of the ABS actuator and ECU when brake pedal is depressed. 2. SYSTEM OPERATION When the wheels are to be locked-up, the solenoid inside the actuator will be controlled by the signal from the ABS actuator and ECU and the brake fluid in the wheel cylinder will flow through the reservoir and reduce the hydraulic pressure. While the ABS is in operation, as the ABS actuator and ECU always outputs the operation signal to the pump inside the actuator, brake fluid stored inside the reservoir will be sucked up by the pump inside the actuator and returned to the master cylinder. When the hydraulic pressure of the wheel cylinder is decompressed or increased until the necessary hydraulic pressure, the solenoid inside the actuator is controlled by the control signal from the ABS actuator and ECU and as a result, hydraulic pressure of the wheel cylinder will be closed at both routes of the master cylinder and reservoir sides and the hydraulic pressure of the wheel cylinder will become to be in the holding condition. If the increase of hydraulic pressure volume of the wheel cylinder becomes necessary, with the control signal from the ABS actuator and ECU, the solenoid inside the actuator will be controlled and become the same condition as usual and the brake fluid of the master cylinder will be sent to the wheel cylinder and will increase the hydraulic pressure of the wheel cylinder. At this time, in the case that the brake fluid stays left in the reservoir, it will be suctioned up by the pump inside the actuator and will be sent to the wheel cylinder. Also, increasing speed of the hydraulic pressure is controlled by outputting the increasing and the said holding one after another.

Malfunction symptoms of the SRS are difficult to confirm, so the DTCs become the most important source of information when troubleshooting. When troubleshooting the SRS, always inspect the DTCs before disconnecting the battery.  Work must be started after 90 seconds from when the ignition switch is turned to the ”LOCK” position and the negative (-) terminal cable is disconnected from the battery. (The SRS is equipped with a back-up power source so that if work is started within 90 seconds from disconnecting the negative (-) terminal cable of the battery, the SRS may be deployed.)  When the negative (-) terminal cable is disconnected from the battery, the memory of the clock and audio system will be canceled. So before starting work, make a record of the contents memorized in the audio memory system. When work is finished, reset the audio systems as they were before and adjust the clock. To avoid erasing the memory in each memory system, never use a back-up power supply from outside the vehicle.  Before repairs, remove the airbag sensor if shocks are likely to be applied to the sensor during repairs.  Do not expose the steering wheel pad, front passenger airbag assembly, side airbag assembly, seat belt pretensioner, airbag sensor assembly, front airbag sensor assembly or side airbag sensor assembly directly to hot air or flames.  Even in cases of a minor collision where the SRS does not deploy, the steering wheel pad, front passenger airbag assembly, side airbag assembly, seat belt pretensioner, airbag sensor assembly, front airbag sensor assembly and side airbag sensor assembly should be inspected.  Never use SRS parts from another vehicle. When replacing parts, replace them with new parts.  Never disassemble and repair the steering wheel pad, front passenger airbag assembly, side airbag assembly, seat belt pretensioner, airbag sensor assembly, front airbag sensor assembly or side airbag sensor assembly in order to reuse it.  If the steering wheel pad, front passenger airbag assembly, side airbag assembly, seat belt pretensioner, airbag sensor assembly, front airbag sensor assembly or side airbag sensor assembly has been dropped, or if there are cracks, dents or other defects in the case, bracket or connector, replace them with new ones.  Use a volt/ohmmeter with high impedance (10 kΩ/V minimum) for troubleshooting the system’s electrical circuits.  Information labels are attached to the periphery of the SRS components. Follow the instructions on the notices.  After work on the SRS is completed, perform the SRS warning light check.  If the vehicle is equipped with a mobile communication system, refer to the precaution in the IN section of the Repair Manual. 2001 AVALON (EWD431U) 205 SRS FROM POWER SOURCE SYSTEM (SEE PAGE 72) ACC AM1 10A SRS- ACC IG1 10 1F IG2 6 GR 7 AM2 B- O ST2 W- R I15 IGNITION SW B4 BODY ECU 7 1C 4 S5 SIDE AIRBAG SENSOR LH IF1 W- R GSW 1 1F L- W LG- B GR- L 4 P- L 3 L 2 GR 1 B- O 7 2C 19 5 B 6 B 4 B 7 A 9 A 10 A 12 A IG2 ACC GSW VUPL SSL+ SSL- ESL 10A AM2 C5 A , C6 B , C7 C CENTER AIRBAG SENSOR ASSEMBLY E2 D- P+ P- 28 B 14 B 13 B 10 B 11 B 5 A 6 A 2 C 1 C W- B Y- B Y Y- R Y- G Y- R Y- G Y- R Y- G 1 B E1 27 B W- B B 2 2G D+ FL+ FL- FR+ FR- 3 1F 4 1F 1 2 1 2 1 2 1 2 F6 A , F7 B FUSIBLE LINK BLOCK 1 A B 3 1B SPIRAL CABLE W- B FL MAIN 3. 0W A27 AIRBAG SQUIB (STEERING WHEEL PAD) BATTERY A26 AIRBAG SQUIB (FRONT PASSENGER AIRBAG ASSEMBLY) IG 2001 AVALON (EWD431U) 206 S7 SIDE AIRBAG SQUIB LH S8 SIDE AIRBAG SQUIB RH FROM POWER SOURCE SYSTEM (SEE PAGE 72) W- B D1 DATA LINK CONNECTOR 1 3 E1 D2 DATA LINK CONNECTOR 2 1 2B B- Y M7 SRS WARNING LIGHT [MULTI DISPLAY] IJ1 5 II2 22 II2 13 3A LG- R 6 B- Y 5 B- Y LG- B TC 4 LG- R 4 TC 11 LG- R LG- B AB 5 12 1A 10 1I 6 4A 4 3G 3 5 1I LG- R 2 4 3B LG- R S6 SIDE AIRBAG SENSOR RH 1 4 LG GR B- Y P- B 6 1F L- Y 6 4H P 5 1F 12 C 10 C 9 C 7 C 3 B 19 B VUPR SSR+ W- B 5A SRS WRN SSR- ESR TC LA C5 A , C6 B , C7 C CENTER AIRBAG SENSOR ASSEMBLY W SIL 12 B Y PR6 C Y- B PR+ 5 C Y PL1 A Y- B PL+ 2 A BR- W - SR 20 B B- W +SR 9 B BR - SL 26 B W- R +SL 15 B C 1 IF2 2 IF2 J5 JUNCTION CONNECTOR BR 2 1 W W- R C 7 1 SIL 1 A12 AIRBAG SENSOR FRONT LH A13 AIRBAG SENSOR FRONT RH 2 P16 PRETENSIONER LH 1 2 D3 DATA LINK CONNECTOR 3 W- B 2 P17 PRETENSIONER RH EB 2001 AVALON (EWD431U) 207 SRS SYSTEM OUTLINE The SRS is a driver and front passenger protection device which has a supplemental role to the seat belts. When the ignition SW is turned to ACC or ON, current from the SRS-ACC fuse flows to TERMINAL (A) 6 of the center airbag sensor assembly. If an accident occurs while driving, when the frontal impact exceeds a set level, current from the SRS-ACC fuse flows to TERMINALS (A) 2, (B) 10, (B) 14 and (C) 5 of the center airbag sensor assembly to TERMINAL 1 of the airbag squibs and the pretensioners to TERMINAL 2 to TERMINALS (A) 1, (B) 11, (B) 13 and (C) 6 of the center airbag sensor assembly to TERMINAL (B) 27, (B) 28 or BODY GROUND to GROUND, so that current flows to the airbag squibs and the pretensioners and causes them to operate. When the side impact also exceeds a set level, current from the SRS-ACC fuse flows to TERMINALS (A) 2, (A) 5, (C) 2 and (C) 5 of the center airbag sensor assembly to TERMINAL 1 of the side airbag squibs and the pretensioners to TERMINAL 2 to TERMINALS (A)1, (A) 6, (C) 1, and (C) 6 of the center airbag sensor assembly to TERMINAL (B) 27, (B) 28 or BODY GROUND to GROUND, causing side airbag squibs and the pretensioners to operate. The airbag stored inside the steering wheel pad is instantaneously expanded to soften the shock to the driver. The airbag stored inside the passenger’s instrument panel is instantaneously expanded to soften the shock to the front passenger. Side airbags are instantaneously expanded to soften the shock of side to the driver and front passenger. The pretensioners make sure of the seat belt restrainability. : PARTS LOCATION Code See Page A12 44 A13 44 46 (Column Shift) A26 Code B C7 C 48 (Floor Shift) D1 46 (Column Shift) A27 46 (Column Shift) C5 A C6 B 46 (Column Shift) 48 (Floor Shift) 46 (Column Shift) D3 48 (Floor Shift) 48 (Floor Shift) 44 D2 48 (Floor Shift) B4 See Page C6 I15 J5 M7 51 51 48 (Floor Shift) S5 51 F6 A 44 S6 51 48 (Floor Shift) F7 B 44 S7 51 47 (Column Shift) S8 51 46 (Column Shift) I15 See Page Junction Block and Wire Harness (Connector Location) 27 Cowl Wire and Driver Side J/B (Lower Finish Panel) 2B 30 Engine Wire and Engine Room J/B (Engine Compartment Left) 2C 30 Engine Room Main Wire and Engine Room J/B (Engine Compartment Left) 2G 30 Engine Wire and Engine Room J/B (Engine Compartment Left) 34 Cowl Wire and J/B No.3 No 3 (Left Kick Panel) 3G 35 Instrument Panel Wire and J/B No.3 (Left Kick Panel) 4A 38 Cowl Wire and J/B No.4 (Right Kick Panel) 4H 39 Instrument Panel Wire and J/B No.4 (Right Kick Panel) 1I 2001 AVALON (EWD431U) 208 49 (Floor Shift) P17 Instrument Panel Wire and Driver Side J/B (Lower Finish Panel) 3B 47 (Column Shift) 46 (Column Shift) 1B 3A 49 (Floor Shift) P16 26 1F 47 (Column Shift) 46 (Column Shift) Code 1C See Page 49 (Floor Shift) 48 (Floor Shift) ,,, : JUNCTION BLOCK AND WIRE HARNESS CONNECTOR ,,, ,,, 1A Code : CONNECTOR JOINING WIRE HARNESS AND WIRE HARNESS Code IF1 IF2 II2 IJ1 See Page Joining Wire Harness and Wire Harness (Connector Location) 56 (Column Shift) 60 (Floor Shift) 56 (Column Shift) Engine Room Main Wire and Cowl Wire (Left Side of Instrument Panel) 60 (Floor Shift) 58 (Column Shift) 62 (Floor Shift) 58 (Column Shift) 62 (Floor Shift) Engine Wire and Cowl Wire (Behind the Glove Box) Engine Wire and Instrument Panel Wire (Right Kick Panel) : GROUND POINTS Code EB IG See Page 54 56 (Column Shift) 60 (Floor Shift) Ground Points Location Surge Tank RH Cowl Side Panel LH 2001 AVALON (EWD431U) 209 CRUISE CONTROL FROM POWER SOURCE SYSTEM (SEE PAGE 72) 10A ECU- IG NO. 2 10A GAUGE NO. 2 5A ECU- ACC 8 1D P1 PARK/NEUTRAL POSITION SW 15 3C 10 II1 Y- R R- L GR 2 3C 4 1 1C (* 4) Y- R 13 1B TO SPEEDOMETER [MULTI DISPLAY] Y- R D 7 3C 2 15 3D 20 3D 20 3C 6 4D 2 Y- R R- L 9 12 D CCS 10 GND C15 CRUISE CONTROL ECU 3 ECT 16 6 5 IDL 13 21 II2 RES/ACC COAST/SET ECC A C12 CRUISE CONTROL SW [COMB.

In this system, the engine throttle valve opening angle is adjusted automatically to control the vehicle at a constant speed. 1. SET CONTROL When the SET/COAST SW is operated while traveling with the main SW ON, the speed when the SW is operated to OFF (SW released) is memorized, and the vehicle speed is controlled at that speed. 2. COAST CONTROL When the SET/COAST SW is operated to ON, the motor in the actuator rotates the throttle valve until it is closed fully to decrease the vehicle speed, and the speed when the SW is operated to OFF is memorized, and the vehicle speed is controlled at that speed. Furthermore, every time the SET/COAST SW is operated momentarily (Approximately 0.5 sec.) to ON, the memorized vehicle speed is decreased by approximately 1.5km/h. 3. ACCEL CONTROL When the RESUME/ACCEL SW is operated to ON, the motor in the actuator rotates the throttle valve to open direction to increase the vehicle speed, and the speed when the SW is operated to OFF is memorized, and the vehicle speed is controlled at that speed. Furthermore, every time the RESUME/ACCEL SW is operated momentarily (Approximately 0.5 sec.) to ON, the memorized vehicle speed is increased by approximately 1.5km/h. 4. MANUAL CANCEL MECHANISM If any of the following signals are input during cruise control traveling, the magnetic clutch of the actuator is turned off, and the current to the motor flows in the direction to close the throttle valve, and cancel the cruise control. (1) Stop lamp SW is ON (Brake pedal is depressed) (2) The CANCEL SW of the control SW is ON (3) MAIN SW is OFF 5. RESUME CONTROL After canceling the cruise control (Except when the main SW is OFF) if the vehicle speed is above the minimum speed limit (Approximately 40km/h, 25mph), operating the RESUME/ACCEL SW from OFF to ON will cause the system to accelerate and resume to the vehicle speed before manual cancellation. 6. OVERDRIVE FUNCTION The overdrive may be cut on an uphill grade, while traveling with the cruise control. After the overdrive is cut, if the vehicle speed reaches the overdrive resume speed (Set speed minus 2km/h), and if the system determines that the uphill grade has finished, the overdrive will resume after the overdrive timer operation. 7.

The electronically controlled transmission, however, electrically controls the line pressure and lock-up pressure etc., through the solenoid valve. Engine control module control of the solenoid valve based on the input signals from each sensor makes smooth driving possible by shift selection for each gear which is most appropriate to the driving conditions at theat time. 1. GEAR SHIFT OPERATION During driving, the engine control module selects the shift for each gear which is most appropriate to the driving conditions, based on input signals from the engine coolant temp. sensor to TERMINAL THW of the engine control module, and also the input signals to TERMINAL NC2+ of the engine control module from the vehicle speed sensor devoted to the electronically controlled transmission. Current is then output to the electronically controlled transmission solenoid. When shifting to 1st speed, current flows from TERMINAL S1 of the engine control module to TERMINAL 3 of the electronically controlled transmission solenoid to GROUND, and continuity to the No.1 solenoid causes the shift. For the 2nd speed, current flows from TERMINAL S1 of the engine control module to TERMINAL 3 of the electronically controlled transmission solenoid to GROUND, and from TERMINAL S2 of the engine control module to TERMINAL 6 of the electronically controlled transmission solenoid to GROUND, and continuity to solenoids No.1 and No.2 cause the shift. For the 3rd speed, there is no continuity to No.1 solenoid, only to No.2, causing the shift. Shifting into 4th speed (Overdrive) takes place when there is no continuity to either No.1 or No.2 solenoid. 2. LOCK -UP OPERATION When the engine control module judges from each signal that lock-up operation conditions have been met, current flows from TERMINAL SL of the engine control module to TERMINAL 2 of the electronically controlled transmission solenoid to GROUND, causing continuity to the lock-up solenoid and causing lock-up operation. 3. STOP LIGHT SW CIRCUIT If the brake pedal is depressed (Stop light SW on) when driving in lock-up condition, a signal is input to TERMINAL STP of the engine control module, the engine control module operates and continuity to the lock-up solenoid is cut. 4. OVERDRIVE CIRCUIT ∗ O/D main SW on When the O/D main SW is turned on (SW point is open), a signal is input to TERMINAL ODMS of the engine control module and engine control module operation causes gear shift when the conditions for overdrive are met. ∗ O/D main SW off When the O/D main SW is turned off (SW point is closed), a signal is input into TERMINAL ODMS of the engine control module, and turns on the O/D off indicator light. This activates the ECU, and the transmission system is controlled not to shift to overdrive.

AVC-LAN is the abbreviation, which stands for Audio Visual Communication-Local Area Network. This is a unified standard co-developed by 6 audio manufactures associated with Toyota Motor Corporation. The Unified standard covers signals, such as audio signal, visual signal, signal for switch indication and communication signal. Radio Receiver Assembly Power Amplifier CD Auto Changer I10058 (b) (c) Objectives Recently the car audio system has been rapidly developed and functions have been changed drastically. The conventional system has been switched to the multi-media type such as a navigation system. At the same time the level of customers needs to audio system has been upgraded. This lies behind this standardization. The concrete objectives are explained below. (1) When products by different manufactures were combined together, there used to be a case that malfunction occurred such as sound did not come out. This problem has been resolved by standardization of signals. (2) Various types of after market products have been able to add or replace freely. (3) Because of the above (2), each manufacture has become able to concentrate on developing products in their strongest field. This has enabled many types of products provided inexpensively. (4) Conventionally, a new product developed by a manufacture could not be used due to a lack of compatibility with other manufactures products. Because of this new standard, users can enjoy compatible products provided for them timely. The above descriptions are the objectives to introduce AVC-LAN. By this standardization, development of new products will no longer cause systematic errors. Thus, this is very effective standard for a product in the future. HINT:     When +B short or GND short is detected in AVC-LAN circuit, communication stops. Accordingly the audio system does not function normally. When audio system is not equipped with a navigation system, audio head unit is the master unit. (When audio system is equipped with a navigation system, radio receiver is the master unit.) The car audio system using AVC-LAN circuit has a diagnosis function. Each product has its own specified numbers called physical address. Numbers are also allotted to each function in one product, which are called logical address. 2001 AVALON (RM808U) Author: Date: 1730 BE-161 BODY ELECTRICAL - AUDIO SYSTEM BE16M-03 INSPECTION 1.

These signals are used to control the ABS system. Each of the front and rear rotors has 48 serrations. When the rotors rotate, a magnetic field emitted by a permanent magnet in the speed sensor generates an AC voltage. Since the frequency of this AC voltage changes in direct proportion to the speed of the rotor, the frequency is used by the ECU to detect the speed of each wheel.

These signals are used to control of the ABS and VSC system. Each of the front and rear rotors has 48 serrations. When the rotors rotate, a magnetic field emitted by a permanent magnet in the speed sensor generates an AC voltage. Since the frequency of this AC voltage changes in direct proportion to the speed of the rotor, the frequency is used by the ECU to detect the speed of each wheel.

If an open or short circuit occurs in either of the shift solenoid valves, the ECM controls the remaining normal shift solenoid valve to allow the vehicle to be operated smoothly (Fail safe function). Fail safe function: If either of the shift solenoid valve circuits develops an open or short, the ECM turns the other shift solenoid ON and OFF to shift to the gear positions shown in the table below. The ECM also turns the shift solenoid valve SL OFF at the same time. If both solenoids are malfunctioning, hydraulic control cannot be performed electronically and must be done manually. Manual shifting as shown in the following table must be done (In the case of a short circuit, the ECM stops sending current to the short circuited solenoid).

The ECM determines optimum operating pressure according to the signals from the throttle position sensor, vehicle speed sensor and direct clutch speed sensor and controls the volume of current flow to the solenoid valve. The amount of current to the solenoid is controlled by the (*) duty ratio of ECM output signals, causing a momentary change to the hydraulic pressure acting on the clutches during gear shifting. When the duty ratio is high, the hydraulic pressure acting on the clutches is low. Accumulator Control Pressure High 0 Electric Current (A) 1 AT5608 (*) Duty Ratio The duty ratio is the ratio of the period of continuity in one cycle.

(a) DIAGNOSIS SYSTEM Description  When troubleshooting OBD II vehicles, the only difference from the usual troubleshooting procedure is that you connect to the vehicle an OBD II scan tool complying with SAE J1987 or TOYOTA handheld tester, and read off various data output from the vehicle’s ECM.  OBD II regulations require that the vehicle’s onboard computer lights up the Malfunction Indicator Lamp (MIL) on the instrument panel when the computer detects a malfunction in the computer itself or in drive system components which affect vehicle emissions. In addition to the MIL lighting up when a malfunction is detected, the applicable DTCs prescribed by SAE J2012 are recorded in the ECM memory (See page DI-14 ). If the malfunction only occurs in 3-trip, the MIL goes off but the DTCs remain recorded in the ECM memory.  To check the DTCs, connect an OBD II scan tool or TOYOTA hand-held tester to DLC3 on the vehicle. The OBD II scan tool or TOYOTA hand-held tester also enables you to erase the DTCs and check freeze frame data and various forms of engine data (For instruction book). DTCs include SAE controlled codes and Manufacturer controlled codes. SAE controlled codes must be set as prescribed by the SAE, while Manufacturer controlled codes can be set freely by the manufacturer within the prescribed limits (See DTC chart on page ). FI0534 TOYOTA hand-held tester  DLC3 F07887 2001 AVALON (RM808U) Author: Date: 316 DI-161 DIAGNOSTICS -   (b) AUTOMATIC TRANSAXLE The diagnosis system operates in normal mode during normal vehicle use, and also has a check mode for technicians to simulate malfunction symptoms and perform troubleshooting. Most DTCs use 2-trip detection logic(*) to prevent erroneous detection. By switching the ECM to check mode when troubleshooting, the technician can cause the MIL to light up and for a malfunction that is only detected once or momentarily (TOYOTA hand-held tester) (See page DI-160 ). *2-trip detection logic: When a logic malfunction is first detected, the malfunction is temporarily stored in the ECM memory. If the same malfunction is detected again during the 2nd test drive, this 2nd detection causes the MIL to light up. Inspect the DLC3. The vehicle’s ECM uses ISO 9141-2 for communication. The terminal arrangement of DLC3 complies with SAE J1962 and matches the ISO 9141-2 format. N09214 Tester connection Condition Specified condition 7 (Bus  Line) - 5 (Signal ground) During communication 4 (Chassis Ground) - Body Always 1 Ω or less 5 (Signal Ground) - Body Always 1 Ω or less 16 (B+) - Body Always 9 - 14 V Pulse generation HINT: If your display shows ”UNABLE TO CONNECT TO VEHICLE” when you have connected the cable of OBD II scan tool or TOYOTA hand-held tester to DLC3, turned the ignition switch ON and operated the scan tool, there is a problem on the vehicle side or tool side.  If communication is normal when the tool is connected to another vehicle, inspect DLC3 on the original vehicle.  If communication is still not possible when the tool is connected to another vehicle, the problem is probably in the tool itself, so consult the Service Department listed in the tool’s instruction manual. 2001 AVALON (RM808U) Author: Date: 317 DI-162 DIAGNOSTICS 2. (a) FI0534 TOYOTA hand-held tester HINT: If the MIL does not light up, troubleshoot the combination meter (See page BE-2 ). (2) When the engine is started, the MIL should go off. If the lamp remains on, the diagnosis system has detected a malfunction or abnormality in the system. (b) Check the DTC. NOTICE: TOYOTA hand-held tester only: When the diagnostic system is switched from normal mode to check mode, it erases all DTCs and freeze frame data recorded in normal mode. So before switching modes, always check the DTCs and freeze frame data, and note them down. (1) Prepare an OBD II scan tool (complying with SAE J1978) or TOYOTA hand-held tester. (2) (4) F07887 AUTOMATIC TRANSAXLE INSPECT DIAGNOSIS (NORMAL MODE) Check the MIL. (1) The MIL comes on when the ignition switch is turned ON and the engine is not running. (3) DLC3 - Connect the OBD II scan tool or TOYOTA handheld tester to DLC3 at the lower of the instrument panel. Turn the ignition switch ON and turn the OBD II scan tool or TOYOTA hand-held tester switch ON. Use the OBD II scan tool or TOYOTA hand-held tester to check the DTCs and freeze frame data and note them down (For operating instructions, see the OBD II scan tool’s instruction book). See page DI-172 to confirm the details of the DTCs. (5) NOTICE: When simulating symptoms with an OBD II scan tool (excluding TOYOTA hand-held tester) to check the DTCs, use normal mode. For codes on the DTCs chart subject to ”2-trip detection logic”, turn the ignition switch OFF after the symptoms have been simulated the 1st time. Then repeat the simulation process again. When the program has DTCs they are recorded in the ECM. 2001 AVALON (RM808U) Author: Date: 318 DI-163 DIAGNOSTICS - AUTOMATIC TRANSAXLE 3. INSPECT DIAGNOSIS (CHECK MODE) HINT: TOYOTA hand- held tester only: Compared to the normal mode, the check mode has high sensing ability to detect malfunctions.

Stall speed: 2,325 − 2,775 rpm Evaluation: Problem Possible cause (a) Stall speed low in D and R positions  Engine output may be insufficient  Stator one-way clutch is operating properly HINT: If more than 600 rpm below the specified value, the torque converter clutch could be faulty. (b) Stall speed high in D position  Line pressure too low  Forward clutch slipping  No.2 one-way clutch not operating properly  O/D clutch slipping 2001 AVALON (RM808U) Author: Date: 324 DI-169 DIAGNOSTICS - AUTOMATIC TRANSAXLE (c) Stall speed high in R position  Line pressure too low  Direct clutch slipping  1st & reverse brake slipping  O/D clutch slipping (d) Stall speed high in D and R positions  Line pressure too low  Improper fluid level  O/D one-way clutch not operating properly (b) Measure the time lag. When the shift lever is shifted while the engine is idling, there will be a certain time lapse or lag before the shock can be felt. This is used for checking the conditions of the O/D direct clutch, forward clutch, and 1st & reverse brake. NOTICE:  Do the test at normal operating fluid temperature 50 - 80 °C (122 - 176 °F).  Be sure to allow 1 minute interval between tests.  Take 3 measurements and take the average value. (1) Connect an OBD II scan tool or TOYOTA hand-held tester to DLC3. (2) Fully apply the parking brake. (3) Start the engine and check idle speed. Idle speed: 700 ± 50 rpm (In N position and air conditioner OFF) (4) Shift the shift lever from N to D position. Using a stop watch, measure the time from when the lever is shifted until the shock is felt. Time lag: N → D Less than 1.2 seconds In the same manner, measure the time lag for N → R. Time lag: N → R Less than 1.5 seconds Evaluation (If N → D time or N → R time lag is longer than the specified): Problem Possible cause N → D time lag is longer  Line pressure too low  Forward clutch worn  O/D one-way clutch not operating N → R time lag is longer  Line pressure too low  Direct clutch worn  1st & reverse brake worn  O/D one-way clutch not operating properly 2001 AVALON (RM808U) Author: Date: 325 DI-170 DIAGNOSTICS - AUTOMATIC TRANSAXLE 7. HYDRAULIC TEST Measure the line pressure. NOTICE:  Do the test at normal operation fluid temperature 50 - 80 °C (122 - 176 °F).  The line pressure test should always be carried out in pairs. One technician should observe the conditions of wheels or wheel stoppers outside the vehicle while the other is doing the test.  Be careful to prevent SST’s hose from interfering with the exhaust pipe. (1) Warm up the ATF. (2) Remove the test plug on the transaxle case front left side and connect SST (See page AX-33 for the location to connect SST). SST 09992-00095 (09992-00231, 09992-00271) (3) Fully apply the parking brake and chock the 4 wheels. (4) Connect an OBD II scan tool or TOYOTA hand-held tester to DLC3. (5) Start the engine and check idling speed. (6) Keep your left foot pressing firmly on the brake pedal and shift into D position. (7) Measure the line pressure when the engine is idling. (8) Depress the accelerator pedal all the way down. Quickly read the highest line pressure when engine speed reaches stall speed. (9) In the same manner, do the test in R position. Specified line pressure: Condition D position kPa (kgf/cm2, psi) R position kPa (kgf/cm2, psi) Idling 401 - 461 (4.1 - 4.7, 58 - 66) 804 - 882 (8.2 - 9.0, 117 - 128) Stall 1,138 - 1,236 (11.6 - 12.6, 165 - 179) 1,716 - 1,854 (17.5 - 18.9, 249 - 269) If the measured pressure is not up to the specified value, recheck the throttle cable adjustment and retest. Evaluation: Problem Possible cause If the measured values at all positions are higher  Throttle cable out of adjustment  Throttle valve defective  Regulator valve defective If the measured values at all positions are lower  Throttle cable out of adjustment  Throttle valve defective  Regulator valve defective  Oil pump defective  O/D direct clutch defective If pressure is low in the D position only  D position circuit fluid leakage  Forward clutch defective If pressure is low in the R position only  R position circuit fluid leakage  Direct clutch defective  1st & reverse brake defective 2001 AVALON (RM808U) Author: Date: 326 DI-171 DIAGNOSTICS Q00224 - AUTOMATIC TRANSAXLE 8. MANUAL SHIFTING TEST HINT: With this test, it can be determined whether the trouble is within the electrical circuit or is a mechanical problem in the transaxle. (a) Disconnect the solenoid wire. (b) Inspect the manual driving operation. Check that the shift and gear positions correspond with the table below. While driving, shift through the L, 2 and D positions. Check that the gear change corresponds to the shift position. Shift Position Gear Position D O/D 2 O/D L 1st R Reverse P Pawl Lock HINT: If the L, 2 and D position gear positions are difficult to positions are difficult to distinguish, do the above read test. If any abnormality is found in the above test, the problem is in the transaxle itself. (c) Connect the solenoid wire.

If a malfunction occurs in the actuator or speed sensor, etc. during cruise control operation, the rotor shaft between the motor and control plate is released. When the brake pedal is depressed, the stop light switch turns on, supplying electrical power to the stop light. Power supply to the magnetic clutch is mechanically cut and the magnetic clutch is turned OFF. When driving downhill, if the vehicle speed exceeds the set speed by 15 km/h (9 mph), the ECU turns the safety magnet clutch OFF. If the vehicle speed later drops to within 10 km/h (6 mph), cruise control at the set speed is resumed.

Terminal ECT of the cruise control ECU detects the shift change signal (output to electronically controlled transmission No. 2 solenoid) from the ECM. If the vehicle speeds down, also when terminal ECT of the cruise control ECU receives down shifting signal, it sends a signal from terminal OD to ECM to cut overdrive until the end of the uphill slope, and the gear shifts are reduced and gear shift points in the electronically controlled transmission are changed.

When the ECU receives this signal, it cancels the cruise control. A fail-safe function is provided so that the cancel functions normally, even if there is a malfunction in the stop light signal circuit. The cancel conditions are: Battery positive voltage at terminal STPWhen the brake is ON, battery positive voltage normally is applied through the STOP fuse and stop light switch to terminal STP- of the ECU, and the ECU turns the cruise control OFF. If the harness connected to terminal STP- has an open circuit, terminal STP- will have battery positive voltage and the cruise control will be turned OFF. Also, when the brake is ON, the magnetic clutch circuit is cut mechanically by the stop light switch, turning the cruise control OFF.

The hot wire air flow meter consists of a platinum hot wire, thermistor and a control circuit installed in a plastic housing. The hot wire air flow meter works on the principle that the hot wire and thermistor located in the intake air bypass of the housing detect any changes in the intake air temperature. The hot wire is maintained at the set temperature by controlling the current flow through the hot wire. This current flow is then measured as the output voltage of the air flow meter. The circuit is constructed so that the platinum hot wire and thermistor provide a bridge circuit with the power transistor controlled so that the potential of A and B remains equal to maintain the set temperature.

A thermistor built in the sensor changes the resistance value according to the intake air temperature. The lower the intake air temperature, the greater the thermistor resistance value, and the higher the intake air temperature, the lower the thermistor resistance value (See Fig. 1). The intake air temperature sensor is connected to the ECM. The 5 V power source voltage in the ECM is applied to the intake air temperature sensor from terminal THA via resistor R. That is, resistor R and the intake air temperature sensor are connected in series. When the resistance value of the intake air temperature sensor changes in accordance with changes in the intake air temperature, the potential at terminal THA also changes. Based on this signal, the ECM increases the fuel injection volume to improve driveability during cold engine operation. If the ECM detects the DTC P0110, it operates the fail-safe function in which the intake air temperature is assumed to be 20°C (68°F).

When the throttle valve is fully closed, a voltage of approximately 0.7 V is applied to terminal VTA of the ECM. The voltage applied to terminals VTA of the ECM increases in proportion to the opening angle of the throttle valve and becomes approximately 2.7 - 5.2 V when the throttle valve is fully opened. The ECM judges the vehicle driving conditions from these signals input from terminals VTA and uses them as one of the conditions for deciding the air-fuel ratio correction, power increase correction and fuel-cut control etc. ECM Throttle Position Sensor VC VTA E2 P24296 DTC No. P0120 DTC Detecting Condition Trouble Area  Open or short in throttle position sensor circuit  Throttle position sensor  ECM Condition (a) or (b) continues: (a) VTA 0.1 V (b) VTA 4.9 V HINT: After confirming DTC P0120, use the OBD II scan tool or TOYOTA hand-held tester to confirm the throttle valve opening percentage and closed throttle position switch condition.

The A/F sensor has the characteristic that provides output voltage* approximately proportional to the existing air-fuel ratio. The A/F sensor output voltage* is used to provide feedback for the ECM to control the airfuel ratio. By the A/F sensor output, the ECM can determine the deviation amount from the stoichiometric air-fuel ratio and control the proper injection time immediately. If the A/F sensor is malfunctioning, ECM is unable to perform accurate air-fuel ratio control. The A/F sensor is equipped with a heater which heats the zirconia element. The heater is controlled by the ECM. When the intake air volume is low (the temp. of the exhaust gas is low), current flows to the heater to heat the sensor for accurate oxygen concentration detection. *: The voltage value changes at the inside of the ECM only.

After that, record them. Turn the ignition switch OFF and wait at least 5 seconds. (f) INSPECTION PROCEDURE HINT:  If is case that DTC besides misfire is memorized simultaneously, first perform the troubleshooting for them. Read freeze frame data using TOYOTA hand-held tester or OBD II scan tool. Because freeze frame data records the engine conditions when the malfunction is detected. When troubleshooting, it is useful for determining whether the vehicle was running or stopped, the engine was warmed up or not, the air-fuel ratio was lean or rich, etc. at the time of the malfunction. When the vehicle is brought to the workshop and the misfire is not occurred, misfire can be confirmed by reproducing the condition or freeze frame data. Also, after finishing the repair, confirm that there is no misfire. (See the confirmation driving pattern) When either of SHORT FT #1, LONG FT #1, SHORT FT #2 or LONG FT #2 in the freeze frame data is besides the range of ±20 %, there is a possibility that the air-fuel ratio is inclining either to ”rich” (-20 % or less) or ”lean” (+20 % or more). When COOLANT TEMP in the freeze frame data is less than 80°C (176°F), there is a possibility or misfire only during warming up. In the case that misfire cannot be reproduced, the reason may be because of the driving with lack or fuel, the use of improper fuel, a stain of ignition plug, and etc.      1 Check wire harness, connector and vacuum hose in engine room.

The DIS improves the ignition timing accuracy, reduces high-voltage loss, and enhances the the overall reliability of the ignition system by eliminating the distributor. The DIS is a 1-cylinder ignition system which ignites one cylinder with one ignition coil. In the 1-cylinder ignition system, the one spark plug is connected to the end of the secondary winding. High voltage generated in the secondary winding is applied directly to the spark plug. The spark of the spark plug pass from the center elecrtode to the ground electrode. The ECM determines ignition timing and outputs the ignition signals (IGT) for each cylinder.

Fuel trim includes short-term fuel trim and long-term fuel trim. Short-term fuel trim is the short-term fuel compensation used to maintain the air-fuel ratio at its ideal theoretical value. The signal from the A/F sensor is approximately proportional to the existing air-fuel ratio, and ECM comparing it with the ideal theoretical value, the ECM reduces fuel volume immediately if the air-fuel ratio is rich and increases fuel volume if it is lean. Long-term fuel trim compensates the deviation from the central value of the short-term fuel trim stored up by each engine tolerance, and the deviation from the central value due to the passage of time and changes of using environment. If both the short-term fuel trim and long-term fuel trim exceed a certain value, it is detected as a malfunction and the MIL lights up.

When DTC P0172 or P0175 is recorded, the actual air-fuel ratio is on the rich side. If the vehicle runs out of fuel, the air-fuel ratio is lean and DTC P0171 or P0174 is recorded. The MIL then comes on. If the total of the short-term fuel trim value and the long-term fuel trim value is within ± 35 % (80°C (176°F) or more), the system is functioning normally. The A/F sensors (bank 1, 2 sensor 1) output voltage and the short-term fuel trim value can be read using the OBD II scan tool or hand-held tester. The ECM controls the voltage of AFR+, AFL+, AFR- and AFL- terminals of ECM to the fixed voltage. Therefore, it is impossible to confirm the A/F sensor output voltage without OBD II scan tool or handheld tester. OBD II scan tool (excluding hand-held tester) displays the one fifth of the A/F sensors (bank 1, 2 sensor 1) output voltage which is displayed on the hand-held tester.

Author: Date: 213 DI-142 DIAGNOSTICS - ENGINE DI08B-09 Starter Signal Circuit CIRCUIT DESCRIPTION When the engine is cranked, the intake air flow is slow, so fuel vaporization is poor. A rich mixture is therefore necessary in order to achieve good startability. While the engine is being cranked, the battery positive voltage is applied to terminal STA of the ECM. The starter signal is mainly used to increase the fuel injection volume for the starting injection control and after-start injection control.

(a) DIAGNOSIS SYSTEM Description  When troubleshooting OBD II vehicles, the only difference from the usual troubleshooting procedure is that you connect the vehicle to the OBD II scan tool complying with SAE J1978 or TOYOTA handheld tester, and read off various data output from the vehicle’s ECM.  S05349 TOYOTA Hand-Held tester A10838 OBD II regulations require that the vehicle’s onboard computer lights up the Malfunction Indicator Lamp (MIL) on the instrument panel when the computer detects a malfunction in the emission control system/components or in the powertrain control components which affect vehicle emissions, or a malfunction in the computer. In addition to the MIL lighting up when a malfunction is detected, the applicable Diagnostic Trouble Codes (DTCs) prescribed by SAE J2012 are recorded in the ECM memory (See page DI-14 ). If the malfunction does not reoccur in 3 consecutive trips, the MIL goes off automatize but the DTC remain recorded in the ECM memory.  To check the DTC, connect the OBD II scan tool or TOYOTA hand-held tester to the Data Link Connector 3 (DLC3) on the vehicle. The OBD II scan tool or TOYOTA hand-held tester also enables you to erase the DTC and check freezed frame data and various forms of engine data (For operating instructions, see the OBD II scan tool’s instruction book.). DTC include SAE controlled codes and manufacturer controlled codes. SAE controlled codes must be set as prescribed by the SAE, while manufacturer controlled codes can be set freely by the manufacturer within the prescribed limits (See DTC chart on page DI-14 ). 2001 AVALON (RM808U) Author: Date: 159 DI-4 DIAGNOSTICS - ENGINE  The diagnosis system operates in normal mode during normal vehicle use. It also has a check mode for technicians to simulate malfunction symptoms and troubleshoot. Most DTC use 2 trip detection logic* to prevent erroneous detection, and ensure thorough malfunction detection. By switching the ECM to check mode when troubleshooting, the technician can cause the MIL to light up for a malfunction that is only detected once or momentarily (TOYOTA hand-held tester only). (See step 2)  *2 trip detection logic: When a malfunction is first detected, the malfunction is temporarily stored in the ECM memory. (1st trip) If the same malfunction is detected again during the second drive test, this second detection causes the MIL to light up. (2nd trip) the 2 trip repeats the same mode a 2nd time (However, the ignition switch must be turned OFF between the 1st trip and 2nd trip.).  Freeze frame data: Freeze frame data records the engine condition when a misfire (DTCs P0300 - P0306) or fuel trim malfunction (DTCs P0171 and P0172) or other malfunction (first malfunction only), is detected. Because freeze frame data records the engine conditions (fuel system, calculated load, engine coolant temperature, fuel trim, engine speed, vehicle speed, etc.) when the malfunction is detected. When troubleshooting, it is useful for determining whether the vehicle was running or stopped, the engine was warmed up or not, the air-fuel ratio was lean or rich, etc. at the time of the malfunction. Priorities for troubleshooting: If troubleshooting priorities for multiple DTCs are given in the applicable DTC chart, these should be followed. If no instructions are given, troubleshoot DTCs according to the following priorities. (1) DTC other than fuel trim malfunction (DTCs P0171 and P0172), and misfire (DTCs P0300 - P0306). (2) Fuel trim malfunction (DTCs P0171 and P0172). (3) Misfire (DTCs P0300 - P0306). 2001 AVALON (RM808U) Author: Date: 160 DI-5 DIAGNOSTICS (b) 1 2 3 4 5 6 7 8 - ENGINE Check the DLC3. The vehicle’s ECM uses ISO 9141-2 for communication. The terminal arrangement of DLC3 complies with SAE J1962 and matches the ISO 9141-2 format. 9 10 11 12 1314 15 16 DLC3 A04550 Terminal No. Connection/Voltage or Resistance Condition 7 Bus  Line/Pulse generation During transmission 4 Chassis Ground ↔ Body Ground/1 Ω or less Always 5 Signal Ground ↔ Body Ground/1 Ω or less Always 16 Battery Positive ↔ Body Ground/9 - 14 V Always HINT: If your display shows UNABLE TO CONNECT TO VEHICLE when you have connected the cable of the OBD II scan tool or TOYOTA hand-held tester to the DLC3, turned the ignition switch ON and operated the scan tool, there is a problem on the vehicle side or tool side.  If communication is normal when the tool is connected to another vehicle, inspect the DLC3 on the original vehicle.  If communication is still not possible when the tool is connected to another vehicle, the problem is probably in the tool itself, so consult the Service Department listed in the tool’s instruction manual. 2. (a) S05349 INSPECT DIAGNOSIS (Normal Mode) Check the MIL. (1) The MIL comes on when the ignition switch is turned ON and the engine is not running. HINT: If the MIL does not light up, troubleshoot the combination meter (See page BE-53 ). (2) When the engine started, the MIL should go off. If the lamp remains on, the diagnosis system has detected a malfunction or abnormality in the system. (b) Check the DTC. NOTICE:  If there is no DTC in the normal mode, check the 1st trip DTC using Continuous Test Results function (Mode 7 for SAE J1979) or the OBD II scan tool or TOYOTA hand-held tester. 2001 AVALON (RM808U) Author: Date: 161 DI-6 DIAGNOSTICS - ENGINE  TOYOTA hand-held tester only: When the diagnosis system is switched from the normal mode to the check mode, it erases all DTC and freezed frame data recorded in the normal mode. So before switching modes, always check the DTC and freezed frame data, and note them down. (1) Prepare the OBD II scan tool (complying with SAE J 1978) or TOYOTA hand-held tester. (2) Connect the OBD II scan tool or TOYOTA handheld tester to the DLC3 at the lower center of the instrument panel. (3) Turn the ignition switch ON and push the OBD II scan tool or TOYOTA hand-held tester switch ON. (4) Use the OBD II scan tool or TOYOTA hand-held tester to check the DTC and freezed frame data and note them down (For operating instructions, see the OBD II scan tool’s instruction book.). If there is no DTC in the normal mode, check the 1st trip DTC using Continuous Test Results function (Mode 7 for SAE J1979) on the OBD II scan tool or TOYOTA hand-held tester. (5) See page DI-14 to confirm the details of the DTC. NOTICE:  When simulating symptoms with an OBD II scan tool (excluding TOYOTA hand-held tester) to check the DTC, use the normal mode. For code on the DTC chart subject to ”2 trip detection logic”, perform the following either action.  Turn the ignition switch OFF after the symptom is simulated the 1st time. Then repeat the simulation process again. When the problem has been simulated twice, the MIL lights up and the DTCs are recorded in the ECM.  Check the 1st trip DTC using Mode 7 (Continuous Test Results) for SAE J1979. (c) Clear the DTC. The DTCs and freezed frame data will be erased by either action.  Operating the OBD II scan tool (complying with SAE J1978) or TOYOTA hand-held tester to erase the codes. (See the OBD II scan tool’s instruction book for operating instructions.)

INSPECT DIAGNOSIS (Check Mode) HINT: TOYOTA hand-held tester only: Compared to the normal mode, the check mode has an increased sensitivity to detect malfunctions. Furthermore, the same diagnostic items which are detected in the normal mode can also be detected in the check mode. Check the DTC. (1) Initial conditions.  Battery positive voltage 11 V or more  Throttle valve fully closed  Transmission in P or N position  A/C switched OFF (2) Turn the ignition switch OFF. (3) Prepare the TOYOTA hand-held tester. (4) Connect the TOYOTA hand- held tester to the DLC3 at the lower center of the instrument panel. (5) Turn the ignition switch ON and push the TOYOTA hand-held tester switch ON. (6) Switch the TOYOTA hand-held tester from the normal mode to the check mode (Check that the MIL flashes.). NOTICE: If the TOYOTA hand-held tester switches the ECM from the normal mode to the check mode or vice-versa, or if the ignition switch is turned from ON to ACC or OFF during the check mode, the DTC and freezed frame data will be erased. (7) Flashing (8) ON OFF 0.13 Seconds FI3605 Start the engine (The MIL goes out after the engine start.). Simulate the conditions of the malfunction described by the customer. NOTICE: Leave the ignition switch ON until you have checked the DTC, etc. (9) After simulating the malfunction conditions, use the TOYOTA hand-held tester diagnosis selector to check the DTC and freezed frame data, etc. 2001 AVALON (RM808U) Author: Date: 163 DI-8 DIAGNOSTICS - ENGINE HINT: Take care not to turn the ignition switch OFF. Turning the ignition switch OFF switches the diagnosis system from the check mode to the normal mode, so all DTC, etc. are erased. (10) After checking the DTC, inspect the applicable circuit. 4. FAIL-SAFE CHART If any of the following codes is recorded, the ECM enters fail-safe mode.

CHECK FOR INTERMITTENT PROBLEMS TOYOTA hand-held tester only: By putting the vehicle’s ECM in the check mode, 1 trip detection logic is possible instead of 2 trip detection logic and sensitivity to detect open circuits is increased. This makes it easier to detect intermittent problems. (1) Clear the DTC (See step 2). (2) Set the check mode (See step 3). (3) Perform a simulation test (See page IN-20 ). (4) Check the connector and terminal (See page IN-30 ). (5) Handle the connector (See page IN-30 ). 6. BASIC INSPECTION When the malfunction code is not confirmed in the DTC check, troubleshooting should be performed in order for all possible circuits to be considered as the cause of the problems. In many cases, by carrying out the basic engine check shown in the following flow chart, the location causing the problem can be found quickly and efficiently. Therefore, use of this check is essential in engine troubleshooting. 1 Is battery positive voltage 11 V or more when engine is stopped? NO Charge or replace battery.

(a) DIAGNOSIS SYSTEM Description ECM controls the function of immobiliser on this vehicle. Data of the immobiliser or DTC can be read form DLC3 of the vehicle. When a trouble occurs on immobiliser, check engine warning light does not light up but DTC inspection is performed. Therefore when there seems to be a trouble on immobiliser, use hand-held tester or SST to check and troubleshoot it. (b) Check the DLC3. The vehicle’s ECM uses ISO 14230 for communication. The terminal arrangement of DLC3 complies with SAE J1962 and matches the ISO 14230 format. Hand-held Tester DLC3 F07887 DLC3 N09214 Terminal No. Connection / Voltage or Resistance Condition 7 Bus  Line / Pulse generation During transmission 4 Chassis Ground ↔ Body Ground / 1 Ω or less Always 16 Battery Positive ↔ Body Ground / 9 ∼ 14 V Always HINT: If your display shows ”UNABLE TO CONNECT TO VEHICLE” when you have connected the cable of the hand-held tester to DLC3, turned the ignition switch ON and operated the handheld tester, there is a problem on the vehicle side or tool side.  If communication is normal when the tool is connected to another vehicle, inspect DLC3 on the original vehicle.  If communication is still not possible when the tool is connected to another vehicle, the problem is probably in the tool itself, so consult the Service Department listed in the tool’s instruction manual. 2001 AVALON (RM808U) Author: Date: 755 DI-600 DIAGNOSTICS - ENGINE IMMOBILISER SYSTEM 2. INSPECT DIAGNOSIS (Normal Mode) (a) Check the DTC using hand-held tester. NOTICE: Hand- held tester only: When the diagnosis system is switched from normal mode to check mode, it erases all DTCs and freezed frame data recorded in normal mode. So before switching modes, always check the DTCs and freezed frame data, and note them down. (1) Prepare the hand-held tester. (2) Connect the hand-held tester to DLC3. (3) Turn the ignition switch ON and push the hand-held tester main switch ON. (4) Use the hand-held tester to check the DTCs and freezed frame data, note them down. (For operating instructions, see the hand-held tester instruction book.) (5) See page DI-601 to confirm the details of the DTCs. (b) Clear the DTC. The following operations will erase the DTCs and freeze frame data. (1) Operating the OBD ll scam tool (complying with SAEJ1978) or hand-held tester to erase the codes. (See the OBD ll scan tool’s instruction book for operating instructions.) (2) Disconnecting the battery terminals or EFI fuse. 2001 AVALON (RM808U) Author: Date: 756 DI-604 DIAGNOSTICS - ENGINE IMMOBILISER SYSTEM DI1AP-17 PROBLEM SYMPTOMS TABLE Symptom Suspect Area See page Immobiliser is not set.

Lean mixture causing misfire High High Rough idle (Black smoke from exhaust) 1. Restricted air filter 2. Plugged PCV valve 3. Faulty SFI systems:  Faulty pressure regulator  Defective ECT sensor  Faulty ECM  Faulty injectors  Faulty throttle position sensor  Faulty MAF meter 2001 AVALON (RM808U) Author: Date: 986 EM-3 ENGINE MECHANICAL - COMPRESSION COMPRESSION EM0CC-03 INSPECTION HINT: If there is lack of power, excessive oil consumption or poor fuel economy, measure the compression pressure. 1. WARM UP AND STOP ENGINE Allow the engine to warm up to normal operating temperature. 2. REMOVE IGNITION COILS (See page IG-5 ) 3. REMOVE SPARK PLUGS Using a 16 mm plug wrench, remove the 6 spark plugs. 4. (a) (b) (c) Compression Gauge P19471 CHECK CYLINDER COMPRESSION PRESSURE Insert a compression gauge into the spark plug hole. Fully open the throttle. While cranking the engine, measure the compression pressure. HINT: Always use a fully charged battery to obtain engine speed of 250 rpm or more. (d) Repeat steps (a) through (c) for each cylinder. NOTICE: This measurement must be done in as short a time as possible. Compression pressure: 1,500 kPa (15.3 kgf/cm2, 218 psi) Minimum pressure: 1,000 kPa (10.2 kgf/cm2, 145 psi) Difference between each cylinder: 100 kPa (1.0 kgf/cm2, 15 psi) or less (e) If the cylinder compression in 1 or more cylinders is low, pour a small amount of engine oil into the cylinder through the spark plug hole and repeat steps (a) through (c) for cylinders with low compression.  If adding oil helps the compression, it is likely that the piston rings and/or cylinder bore are worn or damaged.  If pressure stays low, a valve may be sticking or seating is improper, or there may be leakage past the gasket. 5. REINSTALL SPARK PLUGS 6.

(a) Negative Cable BO4111 (b) FOR VEHICLES EQUIPPED WITH SRS AIRBAG AND SEAT BELT PRETENSIONER The AVALON is equipped with an SRS (Supplemental Restraint System), such as the driver airbag, front passenger airbag assembly, side airbag assembly and seat belt pretensioner. Failure to carry out service operations in the correct sequence could cause the supplemental restraint system to unexpectedly deploy during servicing, possibly leading to a serious accident. Further, if a mistake is made in servicing the supplemental restraint system, it is possible the SRS may fail to operate when required. Before servicing (including removal or installation of parts, inspection or replacement), be sure to read the following items carefully, then follow the correct procedure described in this manual. GENERAL NOTICE (1) Malfunction symptoms of the supplemental restraint system are difficult to confirm, so the diagnostic trouble codes become the most important source of information when troubleshooting. When troubleshooting the supplemental restraint system, always inspect the diagnostic trouble codes before disconnecting the battery (See page DI-349 ). (2) Work must be started after 90 seconds from the time the ignition switch is turned to the ”LOCK” position and the negative (-) terminal cable is disconnected from the battery. (The supplemental restraint system is equipped with a back-up power source so that if work is started within 90 seconds of disconnecting the negative (-) terminal cable from the battery, the SRS may deploy.) When the negative (-) terminal cable is disconnected from the battery, memory of the clock and audio systems will be cancelled. So before starting work, make a record of the contents memorized by the each memory system. Then when work is finished, reset the clock and audio systems as before. To avoid erasing the memory of each memory system, never use a back-up power supply from another battery. 2001 AVALON (RM808U) Author: Date: 10 IN-1 1 INTRODUCTION - FOR ALL OF VEHICLES (3) Even in cases of a minor collision where the SRS does not deploy, the steering wheel pad, front passenger airbag assembly, side airbag assembly and seat belt pretensioner should be inspected (See page RS- 15, RS- 30, RS- 44, RS- 57 and BO-130 ). (4) Never use SRS parts from another vehicle. When replacing parts, replace them with new parts. (5) Before repairs, remove the airbag sensor if shocks are likely to be applied to the sensor during repairs. (6) Never disassemble and repair the airbag sensor assembly, steering wheel pad, front passenger airbag assembly, side airbag assembly or seat belt pretensioner. (7) If the airbag sensor assembly, steering wheel pad, front passenger airbag assembly, side airbag assembly or seat belt pretensioner has been dropped, or if there are cracks, dents or other defects in the case, bracket or connector, replace them with new ones. (8) Do not directly expose the airbag sensor assembly, steering wheel pad, front passenger airbag assembly, side airbag assembly or seat belt pretensioner to hot air or flames.

In general, the ECU controlled system is considered to be a very intricate system requiring a high level of technical knowledge and expert skill to troubleshoot. However, the fact is that if you proceed to inspect the circuits one by one, troubleshooting of these systems is not complex. If you have adequate understanding of the system and a basic knowledge of electricity, accurate diagnosis and necessary repair can be performed to locate and fix the problem. This manual is designed through emphasis of the above standpoint to help service technicians perform accurate and effective troubleshooting, and is compiled for the following major ECU controlled systems: The troubleshooting procedure and how to make use of it are described on the following pages. System Page 1. Engine DI-1 2. Automatic Transaxle DI-158 3. Anti-Lock Brake System With Electronic Brake Force Distribution (EBD) DI-210 4. ABS With EBD & BA & TRAC & VSC System DI-250 5.

If the scan tool or tester cannot communicate with ECU controlled systems when you have connected the cable of the scan tool or tester to DLC3, turned the ignition switch ON and operated the scan tool, there is a problem on the vehicle side or tool side. (1) If communication is normal when the tool is connected to another vehicle, inspect the diagnosis data link line (Busline) or ECU power circuit of the vehicle. (2) If communication is still not possible when the tool is connected to another vehicle, the problem is probably in the tool itself, so perform the Self Test procedures outline in the Tester Operator’s Manual. 2001 AVALON (RM808U) Author: Date: 19 IN-20 INTRODUCTION - HOW TO TROUBLESHOOT ECU CONTROLLED SYSTEMS IN05W-19 HOW TO PROCEED WITH TROUBLESHOOTING Carry out troubleshooting in accordance with the procedure on the following page. Here, only the basic procedure is shown. Details are provided in Diagnostics section, showing the most effective methods for each circuit.

CUSTOMER PROBLEM ANALYSIS In troubleshooting, the problem symptoms must be confirmed accurately and all preconceptions must be cleared away in order to give an accurate judgment. To ascertain just what the problem symptoms are, it is extremely important to ask the customer about the problem and the conditions at the time it occurred. Important Point in the Problem Analysis: The following 5 items are important points in the problem analysis. Past problems which are thought to be unrelated and the repair history, etc. may also help in some cases, so as much information as possible should be gathered and its relationship with the problem symptoms should be correctly ascertained for reference in troubleshooting. A customer problem analysis table is provided in Diagnostics section for each system for your use. Important Points in the Customer Problem Analysis      What ----- Vehicle model, system name When ----- Date, time, occurrence frequency Where ----- Road conditions Under what conditions? ----- Running conditions, driving conditions, weather conditions How did it happen? ----- Problem symptoms (Sample) Engine control system check sheet.

SYMPTOM CONFIRMATION AND DIAGNOSTIC TROUBLE CODE CHECK The diagnostic system in the AVALON fulfills various functions. The first function is the Diagnostic Trouble Code Check in which a malfunction in the signal circuits to the ECU is stored in code in the ECU memory at the time of occurrence, to be output by the technician during troubleshooting. Another function is the Input Signal Check which checks if the signals from various switches are sent to the ECU correctly. By using these check functions, the problem areas can be narrowed down quickly and troubleshooting can be performed effectively. Diagnostic functions are incorporated in the following systems in the AVALON. System Diagnostic Trouble Code Check Input Signal Check (Sensor Check) Diagnostic Test Mode (Active Test)  (with Check Mode)  (with Check Mode)             Engine Automatic Transaxle Anti-Lock Brake System With Electronic Brake Force Distribution (EBD) ABS With EBD & BA & TRAC & VSC System Supplemental Restraint System Cruise Control System Engine Immobilizer System Multiplex Communication System Air Conditioning System  In diagnostic trouble code check, it is very important to determine whether the problem indicated by the diagnostic trouble code is still occurring or occurred in the past but returned to normal at present. In addition, it must be checked in the problem symptom check whether the malfunction indicated by the diagnostic trouble code is directly related to the problem symptom or not. For this reason, the diagnostic trouble codes should be checked before and after the symptom confirmation to determine the current conditions, as shown in the table below. If this is not done, it may, depending on the case, result in unnecessary troubleshooting for normally operating systems, thus making it more difficult to locate the problem, or in repairs not pertinent to the problem. Therefore, always follow the procedure in correct order and perform the diagnostic trouble code check. DIAGNOSTIC TROUBLE CODE CHECK PROCEDURE Diagnostic Trouble Code Check (Make a note of and then clear) Diagnostic Trouble Code Display Confirmation of Symptoms Diagnostic Trouble Code Check Problem symptoms Same diagnostic trouble code is exist displayed Normal code is displayed Normal Code Display Problem Condition Problem is still occurring in the diagnostic circuit The problem is still occurring in a place other than in the diagnostic circuit (The diagnostic trouble code displayed first is either for a past problem or it is a secondary problem) No problem symptoms exist The problem occurred in the diagnostic circuit in the past Problem symptoms Normal code is exist displayed The problem is still occurring in a place other than in the diagnostic circuit No problem symptoms exist The problem occurred in a place other than in the diagnostic circuit in the past Normal code is displayed 2001 AVALON (RM808U) Author: Date: 22 INTRODUCTION - HOW TO TROUBLESHOOT ECU CONTROLLED SYSTEMS IN-23 Taking into account the points on the previous page, a flow chart showing how to proceed with troubleshooting using the diagnostic trouble code check is shown below. This flow chart shows how to utilize the diagnostic trouble code check effectively, then by carefully checking the results, indicates how to proceed either to diagnostic trouble code troubleshooting or to troubleshooting of problem symptoms table.

Therefore, check the wire harness and connectors (See page IN-30 ). 2001 AVALON (RM808U) Author: Date: 23 IN-24 INTRODUCTION - HOW TO TROUBLESHOOT ECU CONTROLLED SYSTEMS 3. SYMPTOM SIMULATION The most difficult case in troubleshooting is when there are no problem symptoms occurring. In such cases, a thorough customer problem analysis must be carried out, then simulate the same or similar conditions and environment in which the problem occurred in the customer’s vehicle. No matter how much experience a technician has, or how skilled he may be, if he proceeds to troubleshoot without confirming the problem symptoms he will tend to overlook something important in the repair operation and make a wrong guess somewhere, which will only lead to a standstill. For example, for a problem which only occurs when the engine is cold, or for a problem which occurs due to vibration caused by the road during driving, etc., the problem can never be determined so long as the symptoms are confirmed with the engine hot condition or the vehicle at a standstill. Since vibration, heat or water penetration (moisture) is likely cause for problem which is difficult to reproduce, the symptom simulation tests introduced here are effective measures in that the external causes are applied to the vehicle in a stopped condition. Important Points in the Symptom Simulation Test: In the symptom simulation test, the problem symptoms should of course be confirmed, but the problem area or parts must also be found out. To do this, narrow down the possible problem circuits according to the symptoms before starting this test and connect a tester beforehand. After that, carry out the symptom simulation test, judging whether the circuit being tested is defective or normal and also confirming the problem symptoms at the same time. Refer to the problem symptoms table for each system to narrow down the possible causes of the symptom. 1 VIBRATION METHOD: When vibration seems to be the major cause. CONNECTORS Slightly shake the connector vertically and horizontally. Shake Slightly WIRE HARNESS Slightly shake the wire harness vertically and horizontally. The connector joint, fulcrum of the vibration, and body through portion are the major areas to be checked thoroughly. Swing Slightly PARTS AND SENSOR Vibrate Slightly Apply slight vibration with a finger to the part of the sensor considered to be the problem cause and check that the malfunction occurs. HINT: Applying strong vibration to relays may result in open relays. V07268 2001 AVALON (RM808U) Author: Date: 24 INTRODUCTION 2 - HOW TO TROUBLESHOOT ECU CONTROLLED SYSTEMS HEAT METHOD: When the problem seems to occur when the suspect area is heated. Heat the component that is the likely cause of the malfunction with a hair dryer or similar object. Check to see if the malfunction occurs. M a l f u n ction NOTICE: (1) Do not heat to more than 60 °C (140 °F). (Temperature is limited not to damage the components.) (2) Do not apply heat directly to parts in the ECU. 3 IN-25 WATER SPRINKLING METHOD: When the malfunction seems to occur on a rainy day or in a high-humidity condition. Sprinkle water onto the vehicle and check to see if the malfunction occurs. NOTICE: (1) Never sprinkle water directly into the engine compartment, but indirectly change the temperature and humidity by applying water spray onto the radiator front surface. (2) Never apply water directly onto the electronic components. HINT: If a vehicle is subject to water leakage, the leaked water may contaminate the ECU. When testing a vehicle with a water leakage problem, special caution must be taken. 4 OTHER: When a malfunction seems to occur when electrical load is excessive. Turn on all electrical loads including the heater blower, head lights, rear window defogger, etc. and check to see if the malfunction occurs.

FI0046 FI0047 FI0048 CONNECTOR CONNECTION AND TERMINAL INSPECTION  For troubleshooting, diagnostic trouble code charts or problem symptom table are provided for each circuit with detailed inspection procedures on the following pages.  When all the component parts, wire harnesses and connectors of each circuit except the ECU are found to be normal in troubleshooting, then it is determined that the problem is in the ECU. Accordingly, if diagnosis is performed without the problem symptoms occurring, refer to Step 8 to replace the ECU. So always confirm that the problem symptoms are occurring, or proceed with inspection while using the symptom simulation method.  The instructions ”Check wire harness and connector” and ”Check and replace ECU” which appear in the inspection procedure, are common and applicable to all diagnostic trouble codes. Follow the procedure outlined below whenever these instructions appear. OPEN CIRCUIT: This could be due to a disconnected wire harness, faulty contact in the connector, a connector terminal pulled out, etc. HINT:  It is rarely the case that a wire is broken in the middle of it. Most cases occur at the connector. In particular, carefully check the connectors of sensors and actuators  Faulty contact could be due to rusting of the connector terminals, to foreign materials entering terminals or a deformation of connector terminals. Simply disconnecting and reconnecting the connectors once changes the condition of the connection and may result in a return to normal operation. Therefore, in troubleshooting, if no abnormality is found in the wire harness and connector check, but the problem disappears after the check, then the cause is considered to be in the wire harness or connectors. SHORT CIRCUIT: This could be due to a contact between wire harness and the body ground or to a short circuit occurred inside the switch, etc. HINT: When there is a short circuit between the wire harness and body ground, check thoroughly whether the wire harness is caught in the body or is clamped properly. 2001 AVALON (RM808U) Author: Date: 30 INTRODUCTION - HOW TO TROUBLESHOOT ECU CONTROLLED SYSTEMS IN-31 2. CONNECTOR HANDLING When inserting tester probes into a connector, insert them from the rear of the connector. When necessary, use mini test leads. For water resistant connectors which cannot be accessed from behind, take good care not to deform the connector terminals. FI7187 Sensor Side ECU Side 3.

Be sure to lift and support the vehicle at the proper locations (See page IN-8 ).  Cancel the parking brake on the level place and shift the transmission in Neutral (or N position).  When jacking up the front wheels of the vehicle at first place stoppers behind the rear wheels.  When jacking up the rear wheels of the vehicle at first place stoppers before the front wheels.  When either the front or rear wheels only should be jacked up, set rigid racks and place stoppers in front and behind the other wheels on the ground.  After the vehicle is jacked up, be sure to support it on rigid racks . It is extremely dangerous to do any work on a vehicle raised on a jack alone, even for a small job that can be finished quickly. Observe the following precautions to avoid damage to the following parts: (1) Do not open the cover or case of the ECU unless absolutely necessary. (If the IC terminals are touched, the IC may be destroyed by static electricity.) (2) To disconnect vacuum hoses, pull off the end, not the middle of the hose. (3) To pull apart electrical connectors, pull on the connector itself, not the wires. Be careful not to drop electrical components, such as sensors or relays. If they are dropped on a hard floor, they should be replaced and not reused. When steam cleaning an engine, protect the electronic components, air filter and emission-related components from water. Never use an impact wrench to remove or install temperature switches or temperature sensors.

When using a vacuum gauge, never force the hose onto a connector that is too large. Use a step-down adapter for adjustment. Once the hose has been stretched, it may leak air. Installation and removal of vacuum hose: (1) When disconnecting vacuum hoses, use tags to identify how they should be reconnected to. (2) After completing a job, double check that the vacuum hoses are properly connected. A label under the hood shows the proper layout. Unless otherwise stated, all resistance is measured at an ambient temperature of 20°C (68°F). Because the resistance may be outside specifications if measured at high temperatures immediately after the vehicle has been running, measurement should be made when the engine has cooled down. 2001 AVALON (RM808U) Author: Date: 7 IN-8 INTRODUCTION - REPAIR INSTRUCTIONS IN0CP-07 VEHICLE LIFT AND SUPPORT LOCATIONS Front JACK POSITION Front.....................

RADIATOR AND HOSES (a) Check that the front of the radiator is clean and not blocked with leaves, dirt or bugs. (b) Check the hoses for cracks, kinks, rot or loose connections. 5. BATTERY ELECTROLYTE LEVEL Check that the electrolyte level of all battery cells is between the upper and lower level lines on the case. 6. BRAKE FLUID LEVEL Check that the brake fluid level is near the upper level line on the see-through reservoirs. 7. ENGINE DRIVE BELTS Check drive belt for fraying, cracks, wear or oiliness. 8. ENGINE OIL LEVEL Check the level on the dipstick with the engine turned off. 9. POWER STEERING FLUID LEVEL  Check the level.  The level should be in the ”HOT” or ”COLD” range depending on the fluid temperature. 10. AUTOMATIC TRANSMISSION FLUID LEVEL (a) Park the vehicle on a level surface. (b) With the engine idling and the parking brake applied, shift the selector into all positions from ”P” to ”L”, and then shift into ”P” position. (c) Pull out the dipstick and wipe off the fluid with a clean rag. Re-insert the dipstick and check that the fluid level is in the ”HOT” range. (d) Do this check with the fluid at normal driving temperature (70 - 80°C, 158 - 176°F). HINT: Wait until the engine cools down (approx. 30 min.) before checking the fluid level after extended driving at high speeds, in hot weather, in heavy traffic or pulling a trailer. 11. EXHAUST SYSTEM If any change in the sound of the exhaust or smell of the exhaust fumes is noticed, have the cause located and corrected. 2001 AVALON (RM808U) Author: Date: 46 PP-65 PREPARATION - AIR CONDITIONING PP0B8-04 EQUIPMENT Voltmeter Ammeter Ohmmeter Test lead Thermometer Sensor, ECT switch Torque wrench Dial indicator Magnetic clutch Plastic hammer Magnetic clutch 2001 AVALON (RM808U) Author: Date: 115 PP-66 PREPARATION - AIR CONDITIONING PP0B9-09 LUBRICANT Item Compressor oil Capacity Classification - ND-OIL 8 or equivalent When replacing condenser 40 cc (1.4 fl.oz.)

Secondary Lock Primary Lock Complete (Secondary Lock Permitted) Primary Lock Incomplete (Secondary Lock Prevented) (b) Fig.1 Power Source Safing Sensor Fig.2 Lock Lock Primary Lock Squibs Twin-Lock Completed AB0089 When the vehicle is involved in a frontal collision in the hatched area (Fig. 1) and the shock is larger than the predetermined level, the SRS is activated automatically. A safing sensor is designed to go on at a smaller deceleration rate than the airbag sensor. As illustrated in Fig. 2, ignition is caused when current flows to the squib, which happens when a safing sensor and the deceleration sensor go on simultaneously. When a deceleration force acts on the sensors, 2 squibs in the driver airbag and front passenger airbag ignite and generate gas. The gas discharging into the driver airbag and front passenger airbag rapidly increases the pressure inside the bags, breaking open the steering wheel pad and instrument panel. Bag inflation then ends, and the bags deflate as the gas is discharged through discharge holes at the bag’s rear or side.

(When locked, make sure that the outer returns to its original position and sound at the time of fitting in can be heard.) HINT:   Slider As the slider slides, do not touch it. Be careful not to deform the release board. If the release board is deformed, replace it with a new one. Slider H01587 2001 AVALON (RM808U) Author: Date: 1532 RS-1 SUPPLEMENTAL RESTRAINT SYSTEM - SRS AIRBAG SRS AIRBAG RS01Y-34 PRECAUTION CAUTION:  The AVALON is equipped with SRS, which comprises a driver airbag, front passenger airbag and side airbag. Failure to carry out service operations in the correct sequence could cause the SRS to unexpectedly deploy during servicing, possibly leading to a serious accident. Further, if a mistake is made in servicing the SRS, it is possible that the SRS may fail to operate when required. Before performing servicing (including removal or installation of parts, inspection or replacement), be sure to read the following items carefully, then follow the correct procedures described in the repair manual.  Work must be started 90 seconds after the ignition switch is turned to the ”LOCK” position and the negative (-) terminal cable is disconnected from the battery. (The SRS is equipped with a back-up power source so that if work is started within 90 seconds from disconnecting the negative (-) terminal cable of the battery, the SRS may be deployed.)  Do not expose the steering wheel pad, front passenger airbag assembly, side airbag assembly, airbag sensor assembly, front airbag sensor or side airbag sensor assembly directly to hot air or flames. NOTICE:  Malfunction symptoms of the SRS are difficult to confirm, so the DTCs become the most important source of information when troubleshooting. When troubleshooting the SRS, always inspect the DTCs before disconnecting the battery.  Even in cases of a minor collision where the SRS does not deploy, the steering wheel pad, front passenger airbag assembly, side airbag assembly, airbag sensor assembly, front airbag sensor and side airbag sensor assembly should be inspected. (See page RS-15 , RS-30 , RS-44 , RS-57 , RS-64 , RS-69 , RS-74 and RS-79 )  Before repairs, remove the airbag sensor if shocks are likely to be applied to the sensor during repairs.  Never use SRS parts from another vehicle. When replacing parts, replace them with new parts.  Never disassemble and repair the steering wheel pad, front passenger airbag assembly, side airbag assembly, airbag sensor assembly, front airbag sensor or side airbag sensor assembly in order to reuse it.  If the steering wheel pad, front passenger airbag assembly, side airbag assembly, airbag sensor assembly, front airbag sensor or side airbag sensor assembly has been dropped, or if there are cracks, dents or other defects in the case, bracket or connector, replace it with new one.  Use a volt/ohmmeter with high impedance (10 kΩ/V minimum) for troubleshooting the system’s electrical circuits.  Information labels are attached to the periphery of the SRS components. Follow the instructions on the notices.  After work on the SRS is completed, perform the SRS warning light check (See page DI-349 ).  When the negative (-) terminal cable is disconnected from the battery, the memory of the clock and audio system will be canceled. So before starting work, make a record of the contents memorized in the audio memory system. When work is finished, reset the audio systems as they were before and adjust the clock. This vehicle has power seat which are all equipped with memory function. However, it is not possible to make a record of the memory contents. So when the work is finished, it will be necessary to explain this fact to the customer, and ask the customer to adjust the features and reset the memory. To avoid erasing the memory in each memory system, never use a back- up power supply from outside the vehicle. 2001 AVALON (RM808U) Author: Date: 1521 RS-2 SUPPLEMENTAL RESTRAINT SYSTEM  - SRS AIRBAG If the vehicle is equipped with a mobile communication system, refer to the precaution in the IN section. 2001 AVALON (RM808U) Author: Date: 1522 RS-13 SUPPLEMENTAL RESTRAINT SYSTEM - STEERING WHEEL PAD AND SPIRAL CABLE STEERING WHEEL PAD AND SPIRAL CABLE RS00Y-47 COMPONENTS Column Upper Cover Spiral Cable Steering Wheel Steering Wheel Lower No. 2 Cover 50 (510, 37) Steering Wheel Lower No. 2 Cover Torx Screw 8.8 (90, 78 in.·lbf) Steering Wheel Pad Column Lower Cover N·m (kgf·cm, ft·lbf) : Specified torque H11885 2001 AVALON (RM808U) Author: Date: 1533 RS-17 SUPPLEMENTAL RESTRAINT SYSTEM - STEERING WHEEL PAD AND SPIRAL CABLE RS0L5-01 DISPOSAL HINT: When scrapping vehicle equipped with an SRS or disposing of a steering wheel pad (with airbag), always first deploy the airbag in accordance with the procedure described below.
