The Drivetrain Control Module (DTCM) controls the 4X4 transfer case shift functions via the actuation of a shift motor and utilizing the feedback of a mode sensor assembly. Communication is handled through the CAN bus. The user selectable transfer case modes include the following: 2WD, 4WD AUTO, 4WD LOCK, 4WD LOW, and Neutral (selections vary with the specific transfer case).
The DTCM is located in the passenger footwell, below the HVAC blower.
