Front Controls Interface Module (FCIM)
WARNING: This page is about a different car, the 2011 Mercury Milan, 2011 Lincoln MKZ, and 2011 Ford Fusion. However, it is still accessible from the selected car via links, so may be relevant.
The Front Controls Interface Module (FCIM) acts as a customer interface with the audio system and the climate control system. When a switch is pressed, a message is broadcast over the MS-CAN. When a climate control switch is pressed, the HVAC module sends a message back to the FCIM to illuminate the correct switches to indicate the status of the climate control system.
