Theory Of Operation

The Remote Radio Switches are hardwired to the Right Steering Wheel Control Switch (Speed Control Switch). The Right Steering Wheel Control Switch (Speed Control Switch) communicates to the Steering Column Control Module (SCCM) via the LIN Bus.

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.
