Steering Wheel Rotation Sensor

On vehicles not equipped with active park assist, the steering wheel rotation speed and direction of travel is determined by the Power Steering Control Module (PSCM) and is sent to the Anti-Lock Brake System (ABS) module over the High Speed Controller Area Network (HS-CAN).

On vehicles equipped with active park assist, the steering wheel rotation sensor directly measures the steering wheel rotation speed and direction of rotation. The sensor is mounted on the Steering Column Control Module (SCCM) and the information is sent to the Anti-Lock Brake System (ABS) module over the High Speed Controller Area Network (HS-CAN).
