Final Drive Control Module
The Final Drive Control Module (FDCM) is a microprocessor-based assembly controlling the Transfer Case. Communication is via the CAN serial bus. Inputs include user selectable 2WD and 4WD modes that include 2WD, 4WD AUTO, 4WD LOW and Neutral.
The FDCM has two electrical connectors and is installed inside the passenger compartment behind the driver side knee bolster and is mounted to the left kick panel. On RHD vehicles the FDCM is located in a mirrored position on the right side.
