INSPECTION AND ADJUSTMENT

>> 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 ANGLE SENSOR 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 vehicle with front wheels in straight-ahead position, then stop.

2. Select “DATA MONITOR”. Then make sure “STR ANGLE SIG” is within 0

±

2.5

°

.

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 memory of the ABS actuator and electric unit (control unit) and ECM.

• ABS actuator and electric unit (control unit): Refer to 

BRC-138, "CONSULT-III Function (ABS)"

.

• ECM: Refer to 

EC-530, "CONSULT-III Function"

.

Are the memories erased?

YES

>> Inspection End.

NO

>> Check the items indicated by the self-diagnosis.

To calibrate the decel G sensor, make sure to use CONSULT-III

(Calibration cannot be done without CONSULT-III)

1.

ALIGN THE VEHICLE STATUS

Stop vehicle with front wheels in straight-ahead position.

>> GO TO 2

2.

PERFORM CALIBRATION OF DECEL G SENSOR

1. On the CONSULT-III screen, touch “WORK SUPPORT” and “DECEL G SEN CALIBRATION” in order.

2. Touch “START”.

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 vehicle with front wheels in straight-ahead position, then stop.

System Description

INFOID:0000000006245988

• Vehicle Dynamics Control system detects driver

′

s steering operation amount and brake pedal travel from

steering angle sensor and pressure sensors. Using information from yaw rate/side/decel G sensor and

wheel sensor, VDC judges driving condition (conditions of under steer and over steer) to improve vehicle

driving stability 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.
