Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Theory Of Operation
The Rear Wiper/Washer Switch is part of the Right Multifunction Switch and is integral to the Steering Column Control Module (SCCM). The SCCM is located at the top end of the Steering Column, underneath the Steering Wheel. The SCCM includes the Clockspring, the Multifunction 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.
