Steering Wheel Position Function

The SCCM module has a steering angle sensor. This sensor records the current steering angle or the current steering movement and transmits this information to the SCCM control unit. The steering angle sensor signal is used internally by the SCCM control unit to reset the turn signal. The SCCM control unit transmits the steering angle information to the ABS/ESP control unit via the HS CAN if the vehicle has ESP (optional). The EHPS also uses this information. For the ESP version, the sensor is "multi-turn" capable, i.e. it can indicate the exact angular position across the entire steering range. Vehicles without ESP are fitted with a simplified version which, after 360° starts again at 0.
