DTC C1290: Steering Angle Sensor Zero Point Malfunction [12/2017 - 09/2018]: Description

The skid control ECU (brake actuator assembly) acquires steering angle sensor zero point every time the engine switch is turned on (IG) and the vehicle is driven at 35 km/h (22 mph) or more for approximately 5 seconds. The skid control ECU (brake actuator assembly) also stores the previous zero point.

If front wheel alignment or the steering wheel position is adjusted without disconnecting the negative battery terminal, or if the acceleration sensor (yaw rate sensor) zero point is not acquired after adjustments have been completed, the skid control ECU (brake actuator assembly) detects the difference between the previous zero point and newly acquired zero point and stores this DTC to indicate a poor adjustment.

The warning operation for the steering angle sensor zero point malfunction will be canceled by turning the engine switch off.
