DTC C1439/66 Steering Angle Sensor Initialization Imcomplete; DTC C1445/66 Vehicle Driven with Steering Angle Sensor not Initialized: Description
WARNING: This page is about a different car, the 2009 Toyota Sequoia. However, it is still accessible from the selected car via links, so may be relevant.
The skid control ECU acquires the steering angle sensor zero point every time the ignition switch is turned to the ON position and the vehicle is driven at 40 km/h (25 mph) or more for approximately 10 seconds.
The ECU also stores previous zero points.
Warning of the steering angle sensor zero point malfunction will be cancelled by turning the ignition switch off.
DTC Chart
| DTC Code | DTC Detection Condition | Trouble Area |
|---|---|---|
| C1439/66 | 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 60 seconds of continuous driving. | - Steering angle sensor - Yaw rate and deceleration sensor - Brake actuator assembly |
| C1445/66 | 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 35 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 |
