Theory Of Operation

The Right Steering Wheel Control Switch (Speed Control Switch) includes the cruise control functions. Cruise Control Functions are resistor multiplexed and are hard wired inputs 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.
