×: Required –: Not required

Work Procedure

INFOID:0000000009757833

ADJUSTMENT OF STEERING ANGLE SENSOR NEUTRAL POSITION

CAUTION:

To adjust neutral position of steering angle sensor, make sure to use CONSULT.

(Adjustment cannot be done without CONSULT).

1.

ALIGN THE VEHICLE STATUS

Stop vehicle with front wheels in straight-ahead position.

>> GO TO 2.

1. On the CONSULT 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”.

±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
