Principles of Operation: Notes
WARNING: This page is about a different car, the 2014 Lincoln MKX and 2014 Ford Edge. However, it is still accessible from the selected car via links, so may be relevant.
There are 2 types of cruise control systems available. The vehicle can be equipped with a standard or adaptive cruise control system. For both standard and adaptive cruise control the systems are controlled by the steering wheel mounted switches (ON/OFF, SET, CNCL, RES and GAP [adaptive only]) that are integrated into the LH steering wheel switch, and by the brake pedal. The cruise control switches are hardwired to the Steering Column Control Module (SCCM). The SCCM sends High Speed Controller Area Network (HS-CAN) messages to the PCM to control the cruise control system.
The clockspring provides the electrical interface between the steering column wiring and the cruise control switches in the steering wheel.
