Safety Warning

DTC C1290/66 Steering Angle Sensor Zero Point Malfunction: Description
The skid control ECU acquires steering angle sensor zero point every time the ignition switch is turned to ON 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 front wheel alignment or the steering wheel position is adjusted without disconnecting the cable from the negative battery terminal, or if 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.
The warning for the steering angle sensor zero point malfunction will be cancelled by turning the ignition switch off.
| DTC Code | DTC Detection Condition | Trouble Area |
|---|---|---|
| C1290/66 | The steering angle sensor zero point calibration position vastly differs from the recorded value. |
