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, the 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 values of the speed sensors are not normal, the 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: Go to next step 

1. Turn the ignition switch off.
2. Turn the ignition switch to ON (READY).
3. Drive the vehicle straight ahead at 35 km/h (22 mph) or more for at least 5 seconds.
4. Check that the centered position of the steering wheel is correctly set while driving straight ahead.

   HINT: 

   If the front wheel alignment and steering wheel position are adjusted as a result of the steering wheel being off-center, 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.

OK: Go to next step 

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