Front Controls Interface Module (FCIM)
WARNING: This page is about a different car, the 2013 Ford Mustang. 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.
