DTC C1290: Abnormal Zero Point of Steering Angle Sensor [02/2019 - 12/2021]: Procedure

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

   Refer to UTILITY [02/2019 - 12/2021]

   Chassis > ABS/VSC/TRAC > Utility 

   Tester Display
   Test Mode

   HINT: 

   • When the stored zero point of the yaw rate and acceleration sensor is cleared, steering 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 sensor zero point cannot be acquired normally even if the vehicle is driven straight ahead at 35 km/h (22 mph) or more.

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 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.
