1. Transfer Case Control Module (TCCM)

The TCCM is responsible for controlling the transfer case’s four-wheel drive system. It receives input from the vehicle’s sensors and adjusts the clutch pack as necessary to deliver power to the front and rear wheels.

2. Encoder Motor

The encoder motor is responsible for shifting the transfer case between different four-wheel drive modes. It receives signals from the TCCM and adjusts the planetary gearset and clutch pack as necessary.

3. Front Axle Switch

The front axle switch is located on the transfer case and is responsible for engaging and disengaging the front axle. It receives signals from the TCCM and adjusts the clutch pack as necessary to engage or disengage the axle.

4. Rear Axle Switch

The rear axle switch is located on the transfer case and is responsible for engaging and disengaging the rear axle. It receives signals from the TCCM and adjusts the clutch pack as necessary to engage or disengage the axle.

5. Vehicle Speed Sensor (VSS)

The VSS provides information about the speed of the vehicle. This information is used by the TCCM to adjust the clutch pack and deliver power to the front and rear wheels.
