Front Controls Interface Module (FCIM)
WARNING: This page is about a different car, the 2008 Mercury Mariner and 2008 Ford Escape. However, it is still accessible from the selected car via links, so may be relevant.
The FCIM acts as the customer interface with the ACM. It resembles a faceplate, and is standard on all audio systems except navigation. The FCIM is a stand-alone module that communicates via the MS-CAN.
