(a) Perform zero point calibration of the yaw rate and acceleration sensor See: Brakes and Traction Control/Antilock Brakes / Traction
Control Systems/Testing and Inspection/Programming and Relearning.
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) Turn the engine switch off.
(b) Start the engine.
(c) Drive the vehicle straight ahead at 35 km/h (22 mph) or more for at least 5 seconds.
(d) Check that the center 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 center position of the steering wheel,
acquire yaw rate and acceleration sensor zero point again after adjusting the front wheel alignment and steering position again.
OK:
The steering wheel is centered correctly.
NG -- ADJUST FRONT WHEEL ALIGNMENT OR STEERING POSITION See: Maintenance/Alignment/Service and
Repair/Front Wheel Alignment
OK -- Continue to next step.
3. RECONFIRM DTC
(a) Turn the engine switch off.
(b) Clear the DTCs See: Brakes and Traction Control/Antilock Brakes / Traction Control Systems/Testing and Inspection/Reading and
Clearing Diagnostic Trouble Codes.
(c) Start the engine.
(d) Drive the vehicle and turn the steering wheel to the right and left at a 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.

HINT
If troubleshooting has been carried out according to Problem Symptoms Table, refer back to the table and proceed to the next
step See: Brakes and Traction Control/Antilock Brakes / Traction Control Systems/Testing and Inspection/Symptom Related
Diagnostic Procedures/Problem Symptoms Table.
B -- REPLACE BRAKE ACTUATOR ASSEMBLY See: Brakes and Traction Control/Antilock Brakes / Traction Control
