Steering Wheel Switches

WARNING: This page is about a different car, the 2014 Ford F-150. 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 SCCM  entertainment system messages are received by the BCM  via HS-CAN  and gatewayed over the Medium Speed Controller Area Network (MS-CAN) where the messages are received by the applicable entertainment system module(s).
