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 the steering angle sensor zero point every time the ignition switch is turned ON and the vehicle is driven at 35 km/h (22 mph) or more for approximately 5 seconds. The ECU also stores previous zero points.

The warning of the steering angle sensor zero point malfunction will be canceled by turning the ignition switch off.
