2.

PERFORM THE NEUTRAL POSITION ADJUSTMENT FOR THE STEERING ANGLE SENSOR

1. On the CONSULT 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-145, "CONSULT Function (ABS)"

.

• ECM: Refer to

EC-53, "CONSULT Function"

.

Are the memories erased?

YES

>> Inspection End
