Theory Of Operation

The Left Steering Wheel Control Switch is 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 steering column shroud, the Steering Angle Sensor (SAS), the Clockspring, the Multi-function Switch, a Steering Column Power Tilt and Telescope Switch (if equipped), Upshift and Downshift Switches (if equipped), and a trim cover. The SCCM is replaced as an entire assembly.
