DTC C1290/66: Steering Angle Sensor Zero Point Malfunction [10/2014 - ]: Procedure

1. Perform zero point calibration of the yaw rate and acceleration sensor (Refer to CALIBRATION [10/2014 - ] ).

   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 

See step  2

1. Turn the power switch off.
2. Turn the power switch 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 steering wheel is centered correctly while driving straight ahead.

   HINT: 

   If front wheel alignment and steering position are adjusted as a result of the steering wheel being off-center, acquire yaw rate and acceleration sensor zero point again after the adjustments are completed.

   OK

   The steering wheel is centered correctly.

Result: 

NG 

ADJUST FRONT WHEEL ALIGNMENT OR STEERING POSITION 

(Refer to ADJUSTMENT [10/2014 - 10/2015] or ADJUSTMENT [10/2015 - ] )

Result: 

OK 

See step  3

1. Turn the power switch off.
2. Clear the DTCs (Refer to DTC CHECK / CLEAR [10/2014 - ] ).
3. Turn the power switch 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 stored (Refer to DTC CHECK / CLEAR [10/2014 - ] ).
