Theory Of Operation

The Rear Wiper/Washer Switch is part of the Multi-function Switch and is integral to the Steering Column Control Module (SCCM). The SCCM is located near the top of the steering column below the steering wheel. The SCCM includes the Clockspring, the Multi-function Switch and a LIN/CAN C Gateway. LIN Bus messages received by the LIN/CAN C Gateway are broadcast over the CAN C Bus to the appropriate modules.
