DTC C1439: Steering Angle Sensor Initialization Incomplete; DTC C1445: Vehicle Driven with Steering Angle Sensor not Initialized [12/2017 - 09/2018]: Description
The skid control ECU (brake actuator assembly) acquires the steering angle sensor zero point every time the engine switch is turned on (IG) and the vehicle is driven at 35 km/h (22 mph) or more for approximately 5 seconds. The ECU also stores previous zero points.
| DTC No. | Detection Item | DTC Detection Condition | Trouble Area | Note |
|---|---|---|---|---|
| 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 0.048 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 10 km/h (6 mph) or more for 30 seconds or more without the brake pedal being depressed. |
