DESCRIPTION
The Front Control Module (FCM) (2) 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
2WD, AWD, 4LOCK, 4LO, and Neutral, depending on the transfer case.
