DESCRIPTION
The skid control ECU acquires steering angle sensor zero point every time the ignition switch is turned to ON and the vehicle is driven at 40 km/h (25 mph) or more for approximately 10 seconds. The ECU also stores the previous zero point.
If the front wheel alignment or steering wheel position is adjusted without disconnecting the cable from the negative (-) battery terminal, or if the yaw rate and acceleration sensor zero point is not acquired after the adjustments have been completed, the skid control ECU detects the difference between the previous zero point and newly acquired zero point and stores this DTC to indicate poor adjustment.
The steering angle sensor zero point malfunction warning is canceled by turning the ignition switch off.

The steering angle sensor zero point calibration position vastly differs from the recorded value. |

PROCEDURE
1. |
PERFORM ZERO POINT CALIBRATION OF YAW RATE AND ACCELERATION SENSOR |
(a) Perform zero point calibration of the yaw rate and acceleration sensor (See
page ).
HINT:

2. |
CHECK STEERING ANGLE SENSOR ZERO POINT CALIBRATION |
(a) Drive the vehicle straight ahead at 40 km/h (25 mph) or more for at least 10 seconds.
(b) Check that the centered position of the steering wheel is correctly set while driving straight ahead.
HINT:
If the front wheel alignment and steering position are adjusted as a result of an abnormal centered position of the steering wheel, acquire the yaw rate and acceleration sensor zero point again after the adjustments are completed.
OK:
The centered position of the steering wheel is correctly set.
