Steering Wheel Controls

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.

The steering wheel controls consist of a series of resistors. Each steering wheel control switch function corresponds with a specific resistance value within the switch. When a switch is pressed, the Steering Column Control Module (SCCM) monitors the change in reference voltage to determine the requested function. The SCCM communicates the switch inputs in a message to the IPC over the HS-CAN . The IPC gateways the message to the ACM and other audio modules over the I-CAN .

For Edge base and premium audio systems without SYNC®, the FCDIM serves as the infotainment display. The 5-way RH steering wheel switch is used to control and navigate the menus in the FCDIM . For Sony® and THX® sound, the RH instrument panel display serves as the infotainment display. The 5-way RH steering wheel switch controls and navigates the menus in the RH instrument panel display.
