AVANZA (EM02Y0E)
Engine Control
System Outline
∗ EFI system
The EFI system monitors the engine condition through the signals, which are input from each sensor to engine ECU.
The best fuel injection volume is decided based on this data and the program memorized by the engine ECU, and the
control signal is output to TERMINALS #10, #20, #30 and #40 of the engine ECU to operate the injector (Inject the fuel).
The EFI system produces control of fuel injection operation by the engine ECU in response to the driving conditions.
∗ ESA system
The ESA system monitors the engine condition through the signals, which are input to the engine ECU from each
sensor. The best ignition timing is decided according to this data and the memorized data in the engine ECU, and the
control signal is output to TERMINALS IG1, IG2, IG3 and IG4. This signal controls the igniter to provide the best ignition
timing for the driving conditions.
∗ Heated oxygen sensor heater control system
The heated oxygen sensor heater control system turns the heater on when the intake air volume is low (Temp. of
exhaust emissions is low), and warms up the heated oxygen sensor to improve detection performance of the sensor.
The engine ECU evaluates the signals from each sensor, current is output to TERMINALS HT1B and HT2B, controlling
the heater.
∗ VVT control
VVT control the intake valve timing in accordance with the engine conditions.
1. Diagnosis System
With the diagnosis system, when there is a malfunction in the engine ECU signal system, the malfunctioning system is
recorded in the memory. The malfunctioning system can be found by reading the code displayed by the check engine
warning lamp.
2. Fail–Safe System
When a malfunction has occurred in any system, 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 ECU memory or else stops the engine.

AVANZA (EM02Y0E)
Front Wiper and Washer
System Outline
With the ignition SW turned on, the current flows to TERMINAL (A) 8 (LHD) or (B) 3 (RHD) of the windshield wiper SW,
TERMINAL 1 of the front washer pump and TERMINAL 4 of the windshield wiper motor through the WIP/WSHR fuse.
1. Low Speed Position
With the windshield wiper SW turned to LO position, the current flows from TERMINAL (A) 8 (LHD) or (B) 3 (RHD) of the
windshield wiper SW to TERMINAL (A) 7 (LHD) or (B) 4 (RHD) to TERMINAL 2 of the windshield wiper motor to GROUND
and causes the windshield wiper motor to run at low speed.
2. High Speed Position
With the windshield wiper SW turned to HI position, the current flows from TERMINAL (A) 8 (LHD) or (B) 3 (RHD) of the
windshield wiper SW to TERMINAL (A) 9 (LHD) or (B) 2 (RHD) to TERMINAL 1 of the windshield wiper motor to GROUND
and causes the windshield wiper motor to run at high speed.
3. INT Position
With the windshield wiper SW turned to INT position, the wiper relay operates and current flows from TERMINAL (A) 8 (LHD)
or (B) 3 (RHD) of the windshield wiper SW to TERMINAL (A) 5 (LHD) or (B) 6 (RHD) to GROUND. This activates the
intermittent circuit and the current flows from TERMINAL (A) 8 (LHD) or (B) 3 (RHD) of the windshield wiper SW to
TERMINAL (A) 7 (LHD) or (B) 4 (RHD) to TERMINAL 2 of the windshield wiper motor to GROUND and the wiper operates.
The intermittent operation is controlled by the charge/discharge function of the condenser installed in the relay.
4. Mist Position
With the windshield wiper SW turned to MIST position, the current flows from TERMINAL (A) 8 (LHD) or (B) 3 (RHD) of the
windshield wiper SW to TERMINAL (A) 7 (LHD) or (B) 4 (RHD) to TERMINAL 2 of the windshield wiper motor to GROUND
and causes the windshield wiper motor to run at low speed.
5. Washer Interlocking Operation
With the washer SW pulled to ON position, the current flows from the WIP/WSHR fuse to TERMINAL 1 of the front washer
pump to TERMINAL 2 to TERMINAL (A) 4 (LHD) or (B) 7 (RHD) of the windshield wiper SW to TERMINAL (A) 5 (LHD) or (B)
6 (RHD) to GROUND and causes the front washer pump to run and the window washer to spray. Simultaneously, current
flows from the WIP/WSHR fuse to TERMINAL (A) 8 (LHD) or (B) 3 (RHD) of the windshield wiper SW to TERMINAL (A) 7
(LHD) or (B) 4 (RHD) to TERMINAL 2 of the windshield wiper motor to GROUND, causing the wiper to function.

1. Manual Down or Up Operation
When the power window regulator master SW is pushed one step, the motor rotates to open the window.
When the power window regulator master SW is pulled up one step, the motor rotates in the opposite direction, to close the
window.
All the other windows can be opened/closed as well, by the operation of the power window regulator master SW or
respective power window regulator SW.
When the window lock SW is pushed to the lock side, the ground circuit to the passenger’s window becomes open. As a
result, even if Open/Close operation of the passenger’s window is attempted, the current from TERMINAL E of the power
window regulator master SW is not grounded and the motor does not rotate, so the passenger’s window can not be operated
and window lock occurs.
2. Auto Down Operation (Driver’s Window)
When the power window regulator master SW is pushed two steps, the motor rotates to open the window automatically.
3. Stopping of Auto Down Operation (Driver’s Window)
Auto operation can be stopped in mid–course with switching power window regulator master SW one step upward during the
down operation.

System Outline
Previous automatic transmissions have selected each gear shift using mechanically controlled throttle hydraulic pressure,
governor hydraulic pressure and lock–up hydraulic pressure. The electronically controlled transmission, however, electrically
controls the line pressure, throttle pressure, lock–up pressure and accumulator pressure etc. through the solenoid valve. The
electronically controlled transmission is a system which precisely controls gear shift timing and lock–up timing in response to
the vehicle’s driving conditions and the engine condition detected by various sensors. It makes smooth driving possible by
shift selection for each gear which is the most appropriate to the driving conditions at that time, and by preventing downing,
squat and gear shift shock when starting off.

AVANZA (EM02Y0E)
System Outline
This system controls the respective brake fluid pressures acting on the brake cylinders of the right front wheel, left front
wheel, and rear wheels when the brakes are applied in a panic stop so that the wheels do not lock.
This results in improved directional stability and steerability during panic braking.
1. Input Signal
(1) Speed sensor signal
The speed of the wheels is detected and input to TERMINALS FL+, FR+, RL+ and RR+ of the skid control ECU with
actuator.
(2) Stop lamp SW signal
A signal is input to TERMINAL STP of the skid control ECU with actuator when the brake pedal is depressed.
2. System Operation
During sudden braking, the skid control ECU with actuator which has signals input from each sensor lets the hydraulic
pressure acting on each wheel cylinder escape to the reservoir.
The pump inside the skid control ECU with actuator is also operating at this time and it returns the brake fluid from the
reservoir to the master cylinder, thus preventing locking of vehicle wheels.
If the skid control ECU with actuator judges that the hydraulic pressure acting on the wheel cylinder is insufficient, the current
acting on the solenoid is controlled and the hydraulic pressure is increased.
Holding of the hydraulic pressure is also controlled by the ECU, by the same method as above, by repeated pressure
reduction. Holding and increase are repeated to maintain vehicle stability and to improve steerability during sudden braking.

AVANZA (EM02Y0E)
SRS
NOTICE: When inspecting or repairing the SRS, perform service in accordance with the following precautionary instructions
and the procedure, and precautions in the Repair Manual applicable for the model year.

D 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.

D Work must be started more than 90 seconds after the ignition SW 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 deploy.)

D When the negative (–) terminal cable is disconnected from the battery, the memory of the clock and audio system will be
cleared. So before starting work, make a record of the contents in the audio memory system. When work is finished,
reset the audio systems as they were before and adjust the clock. Some vehicles have power tilt steering, power
telescopic steering, power seat and power outside rear view mirror which are all equipped with memory function.
However, it is not possible to make a record of these memory contents. So when the work is finished, it will be
necessary to explain it to your customer, and ask the customer to adjust the features and reset the memory. To avoid
erasing the memory in each system, never use a back–up power supply from outside the vehicle.

D Before repair, remove the airbag sensor if shocks are likely to be applied to the sensor during repair.

D Do not expose the following parts directly to hot air or flame;

D Even in cases of a minor collision where the SRS does not deploy, the following parts should be inspected;

D Never use SRS parts from another vehicle. When replacing parts, replace with new parts.

D For the purpose of reuse, never disassemble and repair the following parts.

D If the following parts have been dropped, or have cracks, dents and other defects in their case, bracket, and connector,
replace with new one.

D Use a volt/ohmmeter with high impedance (10 kΩ/V minimum) for troubleshooting electrical circuits of the system.

D Information labels are attached to the periphery of the SRS components. Follow the instructions of the notice.

D After work on the SRS is completed, check the SRS warning light.

D If the vehicle is equipped with a mobile communication system, refer to the precaution in the IN section of the Repair
Manual.

AVANZA (EM02Y0E)
Air Conditioner with Heater
System Outline
Current is applied at all times through the (BLR) fuse to TERMINAL 5 of the (BLR) relay.
When the ignition SW is turned on, the current flows through the IG1/BACK fuse to TERMINAL 2 of the (BLR) relay to
TERMINAL 1 to TERMINAL 8 of the blower SW.
Blower Motor Operation
∗ Low speed operation
When the blower SW is moved to low position, the current flows to TERMINAL 8 of the blower SW to TERMINAL 1 to
GROUND, causing the (BLR) relay to turn on. This causes the current flows from the (BLR) fuse to TERMINAL 5 of the
(BLR) relay to TERMINAL 3 to TERMINAL 2 of the blower motor to TERMINAL 1 to TERMINAL 1 of the blower resistor
to TERMINAL 4 to GROUND, rotating the blower motor at low speed.

∗ Medium speed operation (Operation at medium Low, medium High)

When the blower SW is moved to 2 position, the current flows to TERMINAL 8 of the blower SW to TERMINAL 1 to
GROUND, causing the (BLR) relay to turn on. This causes the current flows from the (BLR) fuse to TERMINAL 5 of the
(BLR) relay to TERMINAL 3 to TERMINAL 2 of the blower motor to TERMINAL 1 to TERMINAL 1 of the blower resistor
to TERMINAL 2 to TERMINAL 6 of the blower SW to TERMINAL 1 to GROUND. At this time, the blower resistance of
the blower resistor is smaller than at low speed, so the blower motor rotates at medium low speed.
When the blower SW is moved to 3 position, the current flows through the (BLR) relay to TERMINAL 2 of the blower
motor to TERMINAL 1 to TERMINAL 1 of the blower resistor to TERMINAL 3 to TERMINAL 5 of the blower SW to
TERMINAL 1 to GROUND. At this time, resistance of the blower resistor is smaller than at 2 position, so the blower
motor rotates at medium high speed.

∗ High speed operation

When the blower SW is moved to high position, the current flows to TERMINAL 8 of the blower SW to TERMINAL 1 to
GROUND, causing the (BLR) relay to turn on.
This causes the current flows from the (BLR) fuse to TERMINAL 5 of the (BLR) relay to TERMINAL 3 to TERMINAL 2 of
the blower motor to TERMINAL 1 to TERMINAL 4 of the blower SW to TERMINAL 1 to GROUND, rotating the blower
motor at high speed.

GROUND, rotating the blower motor at low speed.

∗ Medium speed operation

When the blower SW is moved to medium position, the current flows to TERMINAL 8 of the blower SW to TERMINAL 1
to GROUND, causing the (BLR) relay to turn on. This causes the current flows from the (BLR) fuse to TERMINAL 5 of
the (BLR) relay to TERMINAL 3 to TERMINAL 2 of the blower motor to TERMINAL 1 to TERMINAL (A) 1 (LHD), (B) 2
