MP143 Transfer Case - Operation

OPERATION




MP143 COMPONENT LOCATIONS





In 2WD mode, the front axle and driveshaft turn freely while power is sent to the rear axle and wheels. In 4Lock mode, the front and rear wheels rotate in unison, resulting in remarkable traction. Because this is a part-time system, it locks the front and rear drive shafts together. Therefore, it can only be used on slippery or loose surfaces like ice, gravel, or rugged terrain. The standard-equipment ESP, which combines ABS, Traction Control, and Electronic Roll Mitigation, enhances traction by modulating torque among all wheels as necessary - providing resistance to any wheel that is slipping while allowing torque to flow to the wheels with traction.

The MP143 transfer case also has an analog shift actuator mounted on the rear of the transfer case that communicates with the switch through the CAN-bus network.
