Theory Of Operation
The Flash to Pass/Optical Horn Switch for this vehicle 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 steering column shroud, the Steering Angle Sensor (SAS), the Clockspring, the Multifunction Switch, a Steering Column Power Tilt and Telescope Switch (if equipped), and a trim cover. The SCCM is replaced as an entire assembly.
