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.

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
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.

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.

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.

E GLOSSARY OF TERMS AND SYMBOLS
GROUND
The point at which 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)

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.

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.

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.

The ”Current Flow Chart” section, describes which parts each power source (fuses, fusible links, and circuit breakers)
transmits current to. In the Power Source circuit diagram, the conditions when battery power is supplied to each system
are explained. Since all System Circuit diagrams start from the power source, the power source system must be fully
understood.

ENGINE CONTROL
SYSTEM OUTLINE
This system utilizes an engine control module and maintains overall control of the engine, transmission and so on. 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.

HEADLIGHT (w/ DAYTIME RUNNING LIGHT)
SYSTEM OUTLINE
DAYTIME RUNNING LIGHT OPERATION
When the engine is started, a signal from the generator is input into TERMINAL (B)6 of the body ECU. At this time, if the
parking brake pedal is depressed (Parking brake SW ON), the body ECU is not activated, and the daytime running light
system does not operate.
When the parking brake pedal is released (Parking brake SW OFF), a signal is input into TERMINAL (A)15 of the body ECU.
This activates the body ECU and the headlight turns on.

SYSTEM OUTLINE
When the ignition SW is turned ON, the current flows from WIP fuse to wiper and washer SW TERMINAL 17, washer motor
TERMINAL 2, and front wiper motor TERMINAL 2.
1. LO POSITION
When the wiper and washer SW is at LO position, the current flows from wiper and washer SW TERMINAL 17 to TERMINAL
7 to front wiper motor TERMINAL 5 to TERMINAL 4 to GROUND, and the front wiper motor runs at low speed.
2. HI POSITION
When the wiper and washer SW is at HI position, the current flows from wiper and washer SW TERMINAL 17 to TERMINAL
8 to front wiper motor TERMINAL 3 to TERMINAL 4 to GROUND, and the front wiper motor runs at high speed.
3. INT POSITION
When the wiper and washer SW is at INT position, the wiper relay is activated and the current flows from wiper and washer
SW TERMINAL 17 to TERMINAL 2 to GROUND. This current activates the intermittent circuit, and the current flows from
wiper and washer SW TERMINAL 17 to TERMINAL 7 to front wiper motor TERMINAL 5 to TERMINAL 4 to GROUND, and
operates the front wipers.
4. WASHER CONTINUOUS OPERATION
When the wiper and washer SW is pulled to WASHER position (Washer SW ON posiiton), the current from the WIP fuse
flows to washer motor TERMINAL 2 to TERMINAL 1 to wiper and washer SW TERMINAL 11 to TERMINAL 2 to GROUND,
and operates the washer motor to emitt a water spray. At the same time, the current flows from the WIP fuse to wiper and
washer SW TERMINAL 17 to TERMINAL 7 to front wiper motor TERMINAL 5 to TERMINAL 4 to GROUND, and operates
the front wiper motor.

SYSTEM OUTLINE
In this system, the door control receiver receives the weak radio wave transmitted from the transmitter inside the ignition SW,
and controls remotely the lock/unlock of all the doors and the luggage door, through the communication control of the body
ECU.
1. NORMAL OPERATION
∗ Lock operation
When the lock SW of the transmitter is pushed, all the doors are locked. The answer back buzzer will beep once and the tail
lamps will flash once synchronously.
∗ Unlock operation
When the unlock SW of the transmitter is pushed once, only the driver’s side door is unlocked. The answer back buzzer will
beep twice and the tail lamps will flash twice synchronously. When the unlock SW is pushed again within 3 seconds, all the
doors are unlocked. After the unlock button is pressed the 2nd time, there will be 2 quick beeps (Answer back buzzer) and 2
quick flashes the tail lamps.
∗ Luggage door unlock operation
When the luggage door unlock SW is pushed for a second, the luggage door will open. The answer back buzzer will make a
single, long beep.
2. AUTO LOCK FUNCTION
When the doors are unlocked by the transmitter, but are not actually opened within 30 seconds, all the doors will be locked
again automatically.
3. PANIC MODE FUNCTION
When the panic SW of the transmitter is pushed, the horn comes on, and the headlight and taillight flashes.
4. REPEAT FUNCTION
In case an appropriate lock detection signal is not received after outputting a lock signal when pushing the lock button
(Transmitter), the body ECU output the lock signal again.

SYSTEM OUTLINE
The vehicle could be in an extreme over steering or under steering tendency due to unexpected accidents, road conditions,
vehicle speed, or by other external factors. 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.

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.

SRS
NOTICE: When inspecting or repairing the SRS, perform the operation in accordance with the following precautionary
instructions and the procedure and precautions in the Repair Manual for the applicable model year.
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.

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.

CRUISE CONTROL
SYSTEM OUTLINE
The cruise control system allows to travel at a constant speed, by the operation of the switch, without having to depress the
accelerator pedal. 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. AUTO CANCEL OPERATION
If any of the following conditions are detected, the set speed is erased and the control is canceled.
(1) The motor does not operate
(2) Short in the magnetic clutch
(3) Disconnection in the magnetic clutch (Includes blown STOP fuse)
(4) No vehicle speed signal input
(5) The actual vehicle speed becomes slower than the minimum speed limit

SYSTEM OUTLINE
Previous automatic transaxle have selected each gear shift using the mechanically controlled throttle hydraulic pressure,
governor hydraulic pressure and lock-up hydraulic pressure. 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.

SHIFT LOCK SOLENOID
SYSTEM OUTLINE
When the ignition SW is at ACC position, the current flows from ECU-ACC fuse to shift lock ECU TERMINAL ACC, and at
ON position, the current flows from GAUGE NO.1 fuse to shift lock ECU TERMINAL 3.
1. SHIFT LOCK MECHANISM
When the signals that the brake pedal is depressed (Stop light SW ON) and the shift lever is placed in P position is input into
the shift lock ECU while the ignition SW is ON, the shift lock ECU is activated and the current flows from shift lock ECU
TERMINAL IG to shift lock ECU TERMINAL SLS+ to shift lock solenoid to shift lock ECU TERMINAL SLS- to shift lock ECU
TERMINAL E to GROUND.
As a result, the shift lock solenoid is turned on and (Plate stopper is released) the shift lever can be placed in a position other
than P position.
2. KEY INTERLOCK MECHANISM
When the shift lever is placed to P position with the ignition SW ON or at ACC position, the current from shift lock ECU
TERMINAL KLS+ to key interlock solenoid is cut off. As a result, the key interlock solenoid is turned off (The lock lever is
released from lock position) and the ignition key can be placed to LOCK position from ACC.

INSPECT FOR LEAKAGE OF REFRIGERANT
Perform in these conditions:
Stop engine.
Secure good ventilation (If the gas leak detector
may not react to volatile gases which are not refrigerant, such as evaporated gasoline and exhaust
gas.)
Repeat the test 2 or 3 times.
Make sure that there is some refrigerant remaining
in the refrigeration system.
When compressor is OFF: approx. 392 - 588 kPa
(4 - 6 kgf/ cm2, 57 - 85 psi)
(b)
Bring the gas leak detector close to the drain hose before
performing the test.
Drain Hose
HINT:
N14519
After the blower motor has stopped, leave the cooling unit
for more than 15 minutes.
Expose the gas leak detector sensor under the drain
hose.
When bring the gas leak detector close to the drain hose,
make sure that the gas leak detector does not react to the
volatile gases.
If such reaction is unavoidable, the vehicle must be lifted up.
(c) If gas leak is not detected on the drain hose, remove the
blower resistor from the cooling unit. Then insert the gas
leak detector sensor into the unit and perform the test.
(d) Disconnect the connector and leave the pressure switch
for approx. 20 minutes. Then bring the gas leak detector
close to the pressure switch and perform the test.
(e) Bring the gas leak detector close to the refrigerant lines
and perform the test.

DO NOT OPERATE COMPRESSOR WITHOUT
ENOUGH REFRIGERANT IN REFRIGERATION SYSTEM
If there is not enough refrigerant in the refrigerant system oil lubrication will be insufficient and compressor burnout may occur,
so that care to avoid this, necessary care should be taken.
7.
DO NOT OPEN PRESSURE MANIFOLD VALVE WHILE
COMPRESSOR IS OPERATE
If the high pressure valve is opened, refrigerant flows in the reverse direction and could cause the charging cylinder to rupture, so open and close the only low pressure valve.
8.
BE CAREFUL NOT TO OVERCHARGE SYSTEM WITH
REFRIGERANT
If refrigerant is overcharged, it causes problems such as insufficient cooling, poor fuel economy, engine overheating etc.

DESCRIPTION
OUTLINE OF AVC-LAN
(a) What is AVC-LAN?
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

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.

PRECAUTION
HINT:
Take care to observe the following precautions when performing inspections or removal and replacement
of body electrical related parts.
1.
HEADLIGHT SYSTEM
Halogen bulbs have pressurized gas inside and require special handling. They can burst if scratched or
dropped. Hold a bulb only by its plastic or metal case. Don’t touch the glass part of a bulb with bare hands.
2.
SRS (SUPPLEMENTAL RESTRAINT SYSTEM)
The AVALON is equipped with an SRS (Supplemental Restraint System) such as the driver airbag and front
passenger airbag. Failure to carry out service operation in the correct sequence could cause the SRS to
unexpectedly deploy during servicing, possibly leading to a serious accident. Before servicing (including removal or installation of parts, inspection or replacement), be sure to read the precautionary notices in the
RS section.
3.
AUDIO SYSTEM
If the negative (-) terminal cable is disconnected from the battery, the preset AM, FM 1 and FM 2 stations stored in memory are erased, so make sure to note the stations and reset them after the negative
(-) terminal cable is reconnected to the battery.
If the negative (-) terminal cable is disconnected from the battery, the radio, tape player and CD player
will not operate as well as audio anti - theft system. Be sure to input the correct ID number so that the
radio, tape player and CD player can be operated again.
4.
MOBILE COMMUNICATION SYSTEM
If the vehicle is equipped with a mobile communication system, refer to precautions in the IN section.

NOTICE:
Do not perform circling calibration of the compass in
a place where the earth’s magnetic field is subject to
interference by artificial magnetic fields (underground parking, under a steel tower, between buildings, roof parking, near a crossing, near a large vehicle, etc.).
During calibration, do not operate electric systems
(moonroof, power windows, etc.) as they may interfere with the calibration.
If you want to cancel the calibration before it is complete, push the ”MODE” button again.
HINT:
A compass could be magnetized during by vessels of freight
cars. Before delivery, therefore, make sure to perform calibration and ensure that calibration can be done. If cannot be done
(cannot complete in spite of driving round several times), it may
be caused by magnetization. Demagnetize the vehicle using a
demagnetizer and preform calibration again.

while you register new recognition codes. This mode is
used when adding a transmitter. However, if the number
of registered codes exceeds 4 codes, previously registered codes are correspondingly erased in order, starting
from the first registered code.
The rewrite mode is used to erase all previously registered codes and register only new recognition codes.
The prohibition mode is used to erase all registered codes
and cancels the wireless door lock function. Use this
mode when the transmitter is lost.
The confirmation mode is for confirming few many recognition codes ar already registered before you register
additional recognition codes.

If the radiator cap has contaminations, always rinse
it with water.
When performing steps (a) and (b) below, keep the radiator cap tester at an angle of over 30° above the horizontal.
Before using a radiator cap tester, wet the relief valve
and pressure valve with engine coolant or water.
(a) Using a radiator cap tester, slowly pump the tester and
check that air is coming from the vacuum valve.
Pump speed: 1 push/(3 seconds or more)
NOTICE:
Push the pump at a constant speed.
If air is not coming from the vacuum valve, replace the radiator
cap.
(b) Pump the tester and measure the relief valve opening
pressure.
Pump speed: 1 push within 1 second
NOTICE:
This pump speed is for the first pump only (in order to close
the vacuum valve). After this, the pump speed can be reduced.
Standard opening pressure:
83 - 113 kPa (0.85 - 1.15 kgf/cm2, 12.1 - 16.4 psi)
Minimum opening pressure:
69 kPa (0.7 kgf/cm2, 10.0 psi)

Speed Sensor Circuit
CIRCUIT DESCRIPTION
Rotor
The speed sensor detects wheel speed and sends the appropriate signals to the ECU. 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.

Speed Sensor Circuit
CIRCUIT DESCRIPTION
Rotor
The speed sensor detects a wheel speed and sends the appropriate signals to the ECU. 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.

Vehicle Speed Sensor Malfunction
CIRCUIT DESCRIPTION
The speed sensor for ABS detects the wheel speed and sends the appropriate signals to the ABS ECU.
The ECU converts these signals in to a 4-pulse signal and outputs it to the combination meter.
After this signal is converted into a more precise rectangular waveform by the waveform shaping circuit inside the combination meter, it is then transmitted to the ECM. The ECM determines the vehicle speed based
on the frequency of these pulse signals.

Shift Solenoid A/B Electrical Malfunction (Shift Solenoid Valve No.1/No.2)
CIRCUIT DESCRIPTION
Shifting from 1st to O/D is performed in combination with ON and OFF of the shift solenoid valves No.1 and
No.2 controlled by ECM. 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).

Linear Solenoid for Accumulator Pressure Control
Circuit Malfunction (Shift Solenoid Valve SLN)
CIRCUIT DESCRIPTION
The shift solenoid valve SLN controls the hydraulic pressure
acting on the accumulator control valve when gears are shifted
and performs smooth gear shifting.
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.

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 ).

(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.

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.

Actuator Magnetic Clutch Circuit
CIRCUIT DESCRIPTION
This circuit turns on the magnetic clutch inside the actuator during cruise control operation according to the
signal from the ECU. 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.

Open in Vehicle Speed Sensor Circuit
CIRCUIT DESCRIPTION
The signal from the vehicle speed sensor circuit is sent to cruise control ECU as vehicle speed signal.
The rotor shaft is driven by the gear of the transmission.
For each rotation of the shaft, the vehicle speed sensor sends a 4-pulse signal through the combination
meter to the cruise control ECU (See the following installation).
This signal is converted inside the combination meter and sent as a 4-pulse signal to the cruise control ECU.
The ECU calculates the vehicle speed from this pulse frequency.

Electronically Controlled Transmission Communication Circuit
CIRCUIT DESCRIPTION
When driving uphill under the cruise control, in order to reduce shifting due to ON-OFF overdrive operation
and to provide smooth driving, when down shifting in the electronically controlled transmission occurs, a signal to prevent upshift until the end of the uphill slope is sent from the cruise control ECU to the electronically
controlled transmission.
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.

CRUISE CONTROL SYSTEM
DI08T-17
Stop Light Switch Circuit
CIRCUIT DESCRIPTION
When the brake pedal is depressed, the stop light switch sends a signal to the ECU. 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. (See page DI-563 for operation of the magnetic clutch)

ECM Power Source Circuit
CIRCUIT DESCRIPTION
When the ignition switch is turned ON, battery positive voltage is applied to terminal IGSW of the ECM and
the EFI main relay (Marking: EFI) control circuit in the ECM sends a signal to terminal MREL of the ECM
switching on the EFI main relay.
This signal causes current to flow to the coil, closing the contacts of the EFI main relay and supplying power
to terminal +B of the ECM.
If the ignition switch is turned off, the ECM continues to switch on the EFI main relay for a maximum of 2
seconds for the initial setting of the IAC valve.

Fuel Pump Control Circuit
CIRCUIT DESCRIPTION
In the diagram below, when the engine is cranked, current flows from terminal ST of the ignition switch to
the starter relay (Marking: ST) coil and also current flows to terminal STA of ECM (STA signal).
When the STA signal and NE signal are input to the ECM, Tr is turned ON, current flows to coil of the circuit
opening relay (Marking: C/OPN), the relay switches on, power is supplied to the fuel pump and the fuel pump
operates.
While the NE signal is generated (engine running), the ECM keeps Tr ON (circuit opening relay ON) and the
fuel pump also keeps operating.

Mass Air Flow Circuit Malfunction
CIRCUIT DESCRIPTION
The mass air flow meter uses a platinum hot wire. 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.

P0110
The intake air temperature sensor is built into mass air flow meter and senses the intake air 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).

Throttle/Pedal position Sensor/Switch ”A”
Circuit Malfunction
CIRCUIT DESCRIPTION
The throttle position sensor is mounted in the throttle body and
detects the throttle valve opening angle. 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.

Insufficient Coolant Temp. for Closed Loop
Fuel Control
CIRCUIT DESCRIPTION
To obtain a high purification rate for the CO, HC and NOx components of the exhaust gas, a three-way catalytic converter is used, but for the most efficient use of the three-way catalytic converter, the air-fuel ratio
must be precisely controlled so that it is always close to the stoichiometric air-fuel ratio.
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.

HINT:
After confirming DTC P0125, use the OBD II scan tool or TOYOTA hand−held tester to confirm voltage
output of the A/F sensor (bank 1, 2 sensor 1) from the CURRENT DATA.
The ECM controls the voltage of the AFR+, AFL+, AFR- and AFL- terminals of the ECM to the fixed
voltage. Therefore, it is impossible to confirm the A/F sensor output voltage without the OBDII scan
tool or TOYOTA hand-held tester.

CIRCUIT DESCRIPTION
Misfire: The ECM uses the crankshaft position sensor and camshaft position sensor to monitor changes in
the crankshaft rotation for each cylinder.
The ECM counts the number of times the engine speed change rate indicates that misfire has occurred.
When the misfire rate equals or exceeds the count indicating that the engine condition has deteriorated, the
MIL lights up.
If the misfire rate is high enough and the driving conditions will cause catalyst overheating, the MIL blinks
when misfiring occurs.

Connect the TOYOTA hand-held tester or OBD II scan tool.
Record the DTC and the freeze frame data.
Use the TOYOTA hand-held tester to set to the check mode (See page DI-3 ).
Drive the vehicle several times with the engine speed, load and its surrounding range shown with the
ENGINE SPD, CALC LOAD in the freeze frame data or the MISFIRE RPM, MISFIRE LOAD in the data
list.
If you have no TOYOTA hand-held tester, turn the ignition switch OFF after the symptom is simulated the
first time. Then repeat the simulation process again.

Check whether there is misfire or not by monitoring DTC and the freeze frame data. 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.

CHECK:
(a) Check the connection conditions of wire harness and connector.
(b) Check the disconnection, piping and break of vacuum hose.

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 ENGINE RUN TIME in the freeze frame data is less than 200 seconds, carefully check the
vapor pressure sensor.

CIRCUIT DESCRIPTION
The vapor pressure sensor, VSV for canister closed valve (CCV), VSV for pressure switching valve are used
to detect abnormalities in the evaporative emission control system.
The ECM decides whether there is an abnormality in the evaporative emission control system based on the
vapor pressure sensor signal.
DTCs P0441 and P0446 are recorded by the ECM when evaporative emissions leak from the components
within the dotted line in Fig. 1 below, or when there is a malfunction in either the VSV for EVAP, the VSV for
pressure switching valve, or in the vapor pressure sensor itself.

INSPECTION PROCEDURE
HINT:
If DTC P0441, P0446, P0450 or P0451 is output after DTC P0440 or P0442, first trouble shoot DTC
P0441, P0446 P0450 or P0451. If no malfunction is detected, troubleshoot DTC P0440 or P0442 next.
Read freeze frame data using TOYOTA hand-held tester or OBD II scan tool. Because freeze frame
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 ENGINE RUN TIME in the freeze frame data is less than 200 seconds, carefully check the
VSV for EVAP, charcoal canister and vapor pressure sensor.

Idle Control System Malfunction
CIRCUIT DESCRIPTION
The rotary solenoid type IAC valve is located in front of the intake air chamber and intake air bypassing the throttle valve is
directed to the IAC valve through a passage.
In this way the intake air volume bypassing the throttle valve is
regulated, controlling the engine speed.
The ECM operates only the IAC valve to perform idle-up and
provide feedback for the target idling speed.

HINT:
After confirming DTC P1130, use the OBD II scan tool or TOYOTA hand−held tester to confirm voltage
output of A/F sensor (AFS B1 S1/O2S B1 S1) from the CURRENT DATA.
The A/F sensor’s output voltage and the short−term fuel trim value can be read using the OBD II scan
tool or TOYOTA hand−held tester.
The ECM controls the voltage of the AFR+, AFL+, AFR− and AFL− terminals of the ECM to the fixed
voltage. Therefore, it is impossible to confirm the A/F sensor output voltage without the OBDII scan
tool or TOYOTA hand-held tester.
OBD II scan tool (excluding TOYOTA hand−held tester) displays the one fifth of the A/F sensor output
voltage which is displayed on the TOYOTA hand−held tester.

CIRCUIT DESCRIPTION
A Direct Ignition System (DIS) has been adopted. 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. Based on IGT
signals, the power transistors in the igniter cuts off the current to the primary coil in the ignition coil is supplied
to the spark plug that are connected to the end of the secondary coil. At the same time, the igniter also sends
an ignition confirmation signal (IGF) as a fail-safe measure to the ECM.

VVT Sensor/Camshaft Position Sensor Circuit Malfunction (Bank 2)
CIRCUIT DESCRIPTION
VVT sensor (VV signal) consists of a magnet, iron core and pickup coil.
The VV signal plate has 3 teeth on its outer circumference and is installed the camshaft timing gear.
When the camshafts rotate, the protrusion on the signal plate and the air gap on the pickup coil change,
causing fluctuations in the magnetic field and generating an electromotive force in the pickup coil.
The actual camshaft angle is detected by the VVT sensor and it provides feedback to the ECM to control
the intake valve timing in response to during condition.
DTC No.

DTC
P1780
Park/Neutral Position Switch Malfunction
CIRCUIT DESCRIPTION
The park/neutral position switch go on when the shift lever is in the N or P shift position. When it goes on,
terminal NSW of the ECM is grounded to body ground via the starter relay, thus the terminal NSW voltage
becomes 0V. When the shift lever is in the D, 2, L or R position, the park/neutral position switch goes off,
so the voltage of ECM. Terminal NSW becomes battery voltage, the voltage of the ECM internal power
source. If the shift lever is moved from the N position to the D position, this signal is used for air-fuel ratio
correction and for idle speed control (estimated control), etc.
DTC No.

CIRCUIT DESCRIPTION
Fuel trim refers to the feedback compensation value compared to the basic injection time. 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.

HINT:
When the DTC P0171 or P0174 is recorded, the actual air-fuel ratio is on the lean side. 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.

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 ).

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).

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.

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.

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

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.

PRE-CHECK
1.
(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.

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.

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.

ECU
Position Sensor
(in Motor)
BE3991
The position sensor senses movement of the seat and send
pulse signals to the ECU. The position sensor sends pulse to
the ECU in proportion to the amount of seat movement, as
shown in the diagram on the left.
The ECU uses the number of pulses to constantly calculate the
position relative to the memory position and returns the seat to
the memorized position.
If a malfunction occurs in a position sensor and a sensor signal
is not input to the ECU even when the motor operates, the ECU
prohibits return operation.

Source Voltage Drop
CIRCUIT DESCRIPTION
The SRS is equipped with a voltage-increase circuit (DC-DC converter) in the airbag sensor assembly in
case the source voltage drops.
When the battery voltage drops, the voltage-increase circuit (DC-DC converter) functions to increase the
voltage of the SRS to normal voltage.
The diagnosis system malfunction display for this circuit is different from other circuits that is when the SRS
warning light remains lit up and the DTC is a normal code, source voltage drop is indicated.
Malfunction in this circuit is not recorded in the airbag sensor assembly, and the source voltage returns to
normal, the SRS warning light automatically goes off.
DTC No.

SRS Warning Light Circuit Malfunction
CIRCUIT DESCRIPTION
The SRS warning light is located on the combination meter.
When the SRS is normal, the SRS warning light lights up for approx. 6 seconds after the ignition switch is
turned from the LOCK position to ACC or ON position, and then turns off automatically.
If there is a malfunction in the SRS, the SRS warning light lights up to inform the driver of the abnormality.
When terminals Tc and E1 of the DLC1 are connected, the DTC is displayed by blinking the SRS warning
light.

When the SRS warning light remains lit up and the DTC is the normal code, this means a voltage source
drops.
This malfunction is not stored in memory by the airbag sensor assembly and if the power source voltage returns to normal, the SRS warning light will automatically go out.
When 2 or more codes are indicated, the codes will be displayed in numeral order starting from the
lowest numbered code.
If a code not listed on the chart is displayed, the airbag sensor assembly is faulty.

patterns, normal, 11 and 31 are shown in the illustration.
Normal code indication
The light will blink 2 times per second.
Malfunction code indication
The first blinking output indicates the first digit
of a 2-digit DTC. After a 1.5-second pause,
the second blinking output will indicate the
second digit.
If there are 2 or more codes, there will be a 2.5-second pause
between each code. After all the codes have been output, there
will be a 4.0-second pause and they will all be repeated.
HINT:
In the event of a number of trouble codes, indication will
start from the smallest numbered code.
If a DTC is not output or a DTC is output without terminal
connection, proceed to the Tc terminal circuit inspection
on page DI-484 .

RELEASE METHOD OF AIRBAG ACTIVATION PREVENTION MECHANISM
An airbag activation prevention mechanism is built into the connector for the squib circuit of the SRS.
When release of the airbag activation prevention mechanism is
directed in the troubleshooting procedure, as shown in the illustration of the connectors on the next pages, insert paper
which has the same thickness as the male terminal between the
terminal and the short spring.
CAUTION:
Never release the airbag activation prevention mechanism
on the squib connector.
NOTICE:
Do not release the airbag activation prevention mechanism unless specifically directed by the troubleshooting procedure.
If the inserted paper is too thick the terminal and short
spring may be damaged, so always use paper with
the same thickness as the male terminal.

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.

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.

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.

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.
(9) Use a volt/ohmmeter with high impedance (10 kΩ/V
minimum) for troubleshooting of the electrical circuit.
(10) Information labels are attached to the periphery of
the SRS components. Follow the instructions on the
notices.
(11) After work on the supplemental restraint system is
completed, check the SRS warning light (See page
DI-349 ).
(c)
SPIRAL CABLE (in Combination Switch)
The steering wheel must be fitted correctly to the steering
column with the spiral cable at the neutral position, otherwise cable disconnection and other troubles may result.

GENERAL INFORMATION
A large number of ECU controlled systems are used in the AVALON. 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.

FOR USING OBD II SCAN TOOL OR TOYOTA HAND-HELD TESTER
Before using the scan tool or tester, the scan tool’s instruction book or tester’s operator manual should
be read thoroughly.
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.

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.

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.

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.

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.

HOW TO USE THE DIAGNOSTIC
CHART AND INSPECTION
PROCEDURE
1.
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.

Check the voltage.
In a circuit in which voltage is applied (to the ECU connector terminal), an open circuit can be checked for by conducting a voltage check.
As shown in Fig. 4, with each connector still connected, measure the voltage between body ground
and terminal 1 of connector ”A” at the ECU 5V output terminal, terminal 1 of connector ”B”, and terminal 1 of connector ”C”, in that order.
If the results are:
5V: Between Terminal 1 of connector ”A” and Body Ground
5V: Between Terminal 1 of connector ”B” and Body Ground
0V: Between Terminal 1 of connector ”C” and Body Ground
Then it is found out that there is an open circuit in the wire harness between terminal 1 of ”B” and terminal 1 of ”C”.

REPAIR INSTRUCTIONS
Care must be taken when jacking up and supporting the
vehicle. 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.

REPAIR INSTRUCTIONS
When checking continuity at the wire connector, insert the tester probe carefully to prevent terminals
from bending.
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.

CHECK ENGINE OIL QUALITY
Check the oil for deterioration, entry of water, discoloring or thinning.
If the quality is visibly poor, replace the oil.
Oil grade:
API grade SJ, Energy-Conserving or ILSAC multigrade engine oil.
SAE 5W - 30 is the best choice for your vehicle, for
good fuel economy, and good starting in cold weather.
2.
CHECK ENGINE OIL LEVEL
After warm up the engine and then 5 minutes after the engine
stop, oil level should be between the low level and full level
marks on the dipstick.
If low, check for leakage and add oil up to the full level mark.
NOTICE:
Do not fill with engine oil above the full level mark.

CAUTION:
Prolonged and repeated contact with mineral oil will
result in the removal of natural fats from the skin,
leading to dryness, irritation and dermatitis. In addition, used engine oil contains potentially harmful
contaminants which may cause skin cancer.
Exercise caution in order to minimize the length and
frequency of contact of your skin to used oil. Wear
protective clothing and gloves. Wash your skin thoroughly with soap and water, or use water-less hand
cleaner, to remove any used engine oil. Do not use
gasoline, thinners, or solvents.
In order to preserve the environment, used oil and
used oil filter must be disposed of only at designated
disposal sites.

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.

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.
