DTC C1290/66 Steering Angle Sensor Zero Point Malfunction

DESCRIPTION

DTC Detection Condition:

The skid control ECU acquires the 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 ECU also stores the previous zero point.

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

Warning of the steering angle sensor zero point malfunction will be canceled by turning the engine switch off.
