It can also switch off the front differential locking motor. Once the shifting is possible, the TCCM will finish the process by activating the transfer case encoder actuator. So, how does it do that? The TCCM determines the processing, executing, and verifying the movement using the truck’s speed and the transfer case mode. Where is the transfer case control module located, and what does it do? The transfer case control module is located on the driver side dash, on the steering column.Īs I have explained, the TCCM oversees the shifting in the 4WD vehicle system operation. Its operation requires processing, executing and verifying the completion of the system operation. The transfer case control module (TCCM) controls the general operation of a four-wheel drive. What is the transfer case control module?
So, in this article, we’ll discuss at length the transfer case and how it works and a host of signs and symptoms you may experience when it fails.

Hence, the need to know how to test transfer case shift motor and replace it. If the transfer case fails, you will find it difficult in staying in 4WD or unable to switch from 4WD to AWD, and in rear situations, it’ll affect the rear differential since both of them are mechanically connected. This is quite possible because the transfer case has features that allow the driver to choose whether to transmit power to both rear and front wheels.
Center differential is found on (AWD) while transfer case in four-wheel drive provides superior traction to the truck, thereby giving peak performance in off-road and challenging terrain.
The transfer case is an essential system component that plays a significant role in distinguishing four-wheel drive (4WD) and all-wheel drive (AWD) vehicles.
