DESCRIPTION
The Front Control Module (FCM) contains the software to control the electric shift transfer cases in this vehicle. A separate Transfer Case Control
Module (TCCM) is not used. The FCM is a microprocessor-based assembly, controlling the 4X4 transfer case shift functions via the actuation of a shift
motor and utilizing the feedback of a mode sensor assembly. Communication is via the CAN bus. Inputs include user selectable 4X4 modes that include
AWD, 4LOCK, 4LO, and Neutral.
