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 outputs this DTC to indicate a poor adjustment.

Warning of the steering angle sensor zero point malfunction will be cancelled by turning the ignition switch off.

INSPECTION PROCEDURE

NOTICE:

When replacing the ABS & TRACTION actuator assembly, perform zero point calibration See: Brakes and Traction

Control/Antilock Brakes / Traction Control Systems/Acceleration/Deceleration Sensor/Testing and Inspection/Calibration (to

12/2010).

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: Brakes and Traction Control/Antilock Brakes / Traction

Control Systems/Acceleration/Deceleration Sensor/Testing and Inspection/Calibration (to 12/2010).

HINT

* When the stored zero point of the yaw rate and acceleration sensor is cleared, steering angle sensor zero point will also be

cleared.

* If the zero point and output value of the yaw rate and acceleration sensor and the output value of the speed sensors are not

normal, steering angle sensor zero point cannot be acquired normally even if the vehicle is driven straight ahead at 35 km/h

(22 mph) or more.

NEXT -- Continue to next step.

2. CHECK STEERING ANGLE SENSOR ZERO POINT CALIBRATION

(a) Drive the vehicle straight ahead at 35 km/h (22 mph) or more for at least 5 seconds.

(b) Check that the centered position of the steering wheel is correctly set while driving straight ahead.

HINT

If front wheel alignment and steering position are adjusted as a result of abnormal centered position of the steering wheel, acquire

yaw rate and acceleration sensor zero point again after the adjustments are completed.

OK:

The centered position of the steering wheel is correctly set.

NG -- ADJUST FRONT WHEEL ALIGNMENT OR STEERING POSITION

OK -- Continue to next step.

3. RECONFIRM DTC

(a) Turn the ignition switch off.

(b) Clear the DTC See: Brakes and Traction Control/Antilock Brakes / Traction Control Systems/Testing and Inspection/Reading and

Clearing Diagnostic Trouble Codes/DTC Check / Clear (to 12/2010).

(c) Start the engine.

(d) Drive the vehicle and turn the steering wheel to the right and left at the speed of 35 km/h (22 mph) or more.

(e) Check if the same DTC is recorded See: Brakes and Traction Control/Antilock Brakes / Traction Control Systems/Testing and

Inspection/Reading and Clearing Diagnostic Trouble Codes/DTC Check / Clear (to 12/2010).
