WARNING: This page is about a different variant/trim than selected.
The Speed Control Switch is hardwired 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 Multi-function Switch, a Steering Column Power Tilt and Telescope Switch (if equipped), and a trim cover. The speed control messages are bussed to the Powertrain Control Module (PCM) via the Can Bus.
