DTC C1439: Steering Angle Sensor Initialization Incomplete; DTC C1445: Vehicle Driven with Steering Angle Sensor not Initialized [06/2017 - 10/2020]: Description
When the vehicle is being driven in a straight line at 15 km/h (9 mph) for 1 second or more, the skid control ECU (brake actuator assembly) calculates the steering angle sensor zero point and updates the zero point if the difference between the calculated zero point and current zero point is between 10° and 15°. The ECU also stores previous zero points.
| DTC No. | Detection Item | DTC Detection Condition | Trouble Area |
|---|---|---|---|
| C1439 | Steering Angle Sensor Initialization Incomplete | After the steering angle sensor zero point calibration is cleared due to, for example, fluctuations in the power source, the steering angle sensor zero point calibration cannot be obtained for 115 seconds of continuous driving. |
|
| C1445 | Vehicle Driven with Steering Angle Sensor not Initialized | Steering angle sensor zero point calibration cannot be obtained when the vehicle is driven without a record of steering angle sensor zero point calibration at a speed of 15 km/h (9 mph) or more for 115 seconds or more without the brake pedal being depressed. |
