Four Wheel Drive (4WD) Systems

Component Description

Active Torque Coupling (ATC) Solenoid

The ATC (Active Torque Coupling) is part of the rear differential. The ATC (Active Torque Coupling) solenoid is not repairable. If a new component is required, the ATC (Active Torque Coupling) is installed new as an assembly with the rear axle. REFER to Axle Assembly .

Powertrain Control Module (PCM)

The PCM (Powertrain Control Module) controls the AWD (All-Wheel Drive) system based upon multiple inputs received via HS-CAN (High Speed Controller Area Network).

All-Wheel Drive (AWD) Relay Module

The AWD (All-Wheel Drive) relay module receives and returns information between the PCM (Powertrain Control Module) and the ATC (Active Torque Coupling) over hard wired circuits.

All Terrain Control Module (ATCM)

The ATCM (All Terrain Control Module) sends the driver selected rotary switch mode via the HS-CAN (High Speed Controller Area Network) to multiple systems.
