PRECAUTIONS FOR DIAGNOSIS
If steering angle sensor, steering system parts, suspension system parts, ABS actuator and electric unit (con-
trol unit) or tires have been replaced, or if wheel alignment has been adjusted, be sure to adjust neutral posi-
tion of steering angle sensor before driving. Refer to BRC-66, "

Stop the vehicle with front wheels in straight-ahead position.
>> GO TO 2.
2.PERFORM THE NEUTRAL POSITION ADJUSTMENT FOR THE STEERING ANGLE SENSOR
1. On the CONSULT-III screen, touch "WORK SUPPORT" and “ST ANG SEN ADJUSTMENT" in order.
2. Touch “START”.

CAUTION:
Do not touch steering wheel while adjusting steering angle sensor.
3. After approximately 10 seconds, touch “END”.
NOTE:
After approximately 60 seconds, it ends automatically.
4. Turn ignition switch OFF, then turn it ON again.
CAUTION:
Be sure to perform above operation.
>> GO TO 3.
3.CHECK DATA MONITOR
1. Run the vehicle with front wheels in straight-ahead position, then stop.
2. Select “STR ANGLE SIG” in “DATA MONITOR” and check steering angle sensor signal.
Is the steering angle within the specified range?
YES >> GO TO 4.
NO >> Perform the neutral position adjustment for the steering angle sensor again, GO TO 1.
4.ERASE THE SELF-DIAGNOSIS MEMORY
Erase the self-diagnosis memories of the ABS actuator and electric unit (control unit) and ECM.
 ABS actuator and electric unit (control unit): Refer to BRC-80, "
CONSULT-III Function".
 ECM: Refer to EC-113, "
CONSULT-III Function".
Are the memories erased?
YES >> INSPECTION END
NO >> Check the items indicated by the self-diagnosis. STR ANGLE SIG : 0±2.5°

System DiagramINFOID:0000000003766885
System DescriptionINFOID:0000000003766886
 Vehicle Dynamics Control system detects driver′s steering operation amount and brake pedal travel from
steering angle sensor and pressure sensor. Using information from yaw rate/side G sensor and wheel sen-
sor, VDC judges driving condition (conditions of under steer and over steer) to improve vehicle driving stabil-
ity by controlling brake application to 4 wheels and engine output.
 During VDC operation, it informs driver of system operation by flashing SLIP indicator lamp.
 Electrical system diagnosis by CONSULT-III is available.

System DiagramINFOID:0000000003767312
System DescriptionINFOID:0000000003766890
 Traction Control System is a function that electronically controls engine torque, brake fluid pressure and
CVT shift position to ensure the optimum slippage ratio at drive wheels by computing wheel speed signals
from 4 wheel sensors. When ABS actuator and electric unit (control unit) detects a spin at drive wheels (rear
wheels), it compares wheel speed signals from all 4 wheels. At this time, LH and RH rear brake fluid pres-
sure are controlled, while fuel being cut to engine and throttle valve being closed to reduce engine torque by
the control unit. Further more, throttle position is continuously controlled to ensure the optimum engine
torque at all times.
 During TCS operation, TCS informs driver of system operation by flashing SLIP indicator lamp.
 Electrical system diagnosis by CONSULT-III is available.
