Front Control Module (FCM)

Front Control Module:

The Front Control Module (FCM) (2) is located in the engine compartment below the Power Distribution Center (PDC). The FCM's primary function is to define communications between electronic controllers and move data collected from the multiple controllers to the host controller for processing using Controller Area Network (CAN), Programmable Communication Interface (PCI) buss or J1850. The FCM does not contain any drivers, and therefore does not directly operate any vehicle components.
