DTC C1439/66 Steering Angle Sensor Initialization Incomplete; DTC C1445/66 Vehicle Driven with Steering Angle Sensor not Initialized: 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 40 km/h (25 mph) or more for approximately 10 seconds. The ECU also stores the previous zero point.
The steering angle sensor zero point malfunction warning will be cancelled by turning the ignition switch to off.
DTC Chart
| DTC Code | DTC Detection Condition | Trouble Area |
|---|---|---|
| C1439/66 | After the steering angle sensor 0 calibration is cleared due to, for example, fluctuations in the power source, the steering angle 0 calibration cannot be obtained for 60 seconds of continuous driving | Steering angle sensor Yaw rate and deceleration sensor Brake actuator assembly (Skid control ECU) |
| C1445/66 | Steering angle sensor 0 calibration cannot be obtained when the vehicle is driven without a record of steering angle sensor 0 calibration at a speed of 36 km/h (22 mph) or more for 30 seconds or more without the brake pedal being depressed | Steering angle sensor Yaw rate and deceleration sensor Brake actuator assembly (Skid control ECU) |
