Steering Wheel Switches

WARNING: This page is about a different car, the 2012 Ford Pickup, 2012 Ford F550 Super Duty, 2012 Ford F450 Super Duty, and 2012 Ford Cab & Chassis. However, it is still accessible from the selected car via links, so may be relevant.

The steering wheel switches are mounted directly to the steering wheel and wired to the SCCM. Depending on what features the vehicle is equipped with, the SCCM sends messages via the HS-CAN to the PCM (cruise control), Instrument Panel Cluster (IPC) (message center) and BCM (entertainment system). The BCM receives the SCCM entertainment system messages via the HS-CAN and sends them over the Medium Speed Controller Area Network (MS-CAN), where the messages are received by the applicable entertainment system module(s).
