DTC C1439: Steering Angle Sensor Initialization Incomplete; DTC C1445: Vehicle Driven with Steering Angle Sensor not Initialized [08/2015 - ]: 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 50 km/h (31 mph) or more for approximately 30 seconds. The ECU also stores previous zero points.
| DTC No. | DTC Detection Condition | Trouble Area |
|---|---|---|
| C1439 | After the steering angle sensor zero point calibration at a speed of 15 km/h (9 mph) or more for 1 second or more is cleared due to, for example, fluctuations in the power source, the steering angle sensor zero point calibration cannot be obtained. |
|
| C1445 | 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. |
