DTC C1290: Steering Angle Sensor Zero Point Malfunction [08/2015 - 08/2019]: Description

The skid control ECU acquires the steering angle sensor zero point every time the ignition switch is turned to ON and the vehicle is driven at 40 km/h (25 mph) or more for approximately 10 seconds. The ECU also stores the previous zero point.

If the front wheel alignment or steering wheel position is adjusted without disconnecting the cable from 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 stores this DTC to indicate a poor adjustment.

The steering angle sensor zero point malfunction warning is canceled by turning the ignition switch off.

DTC No. DTC Detection Condition Trouble Area
C1290 The steering angle sensor zero point calibration position vastly differs from the recorded value.
  • Yaw rate and acceleration sensor zero point calibration incomplete
  • Poor adjustment of centered position of steering wheel
  • Poor adjustment of front wheel alignment
