DTC C1290/66: Steering Angle Sensor Zero Point Malfunction: Procedure

1. Perform zero point calibration of the yaw rate and acceleration sensor. Refer to CALIBRATION .

   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, a correct steering angle sensor zero point cannot be acquired even if the vehicle is driven straight ahead at 35 km/h (22 mph) or more.

NEXT: Go to next step 

1. Turn the engine switch off.
2. Start the engine.
3. Drive the vehicle straight ahead at 35 km/h (22 mph) or more for at least 5 seconds.
4. Check that the center 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 an off-centered steering wheel, acquire the yaw rate and acceleration sensor zero point again after adjusting front wheel alignment and steering center position again.

   OK

   The center position of the steering wheel is correctly set.

OK: Go to next step 

1. Turn the engine switch off.
2. Clear the DTCs. Refer to DTC CHECK / CLEAR .
3. Start the engine.
4. Drive the vehicle and turn the steering wheel to the right and left at a speed of 35 km/h (22 mph) or more.
5. Check if the same DTC is recorded. Refer to DTC CHECK / CLEAR .
