Transfer Case Actuator: Description and Operation
NV243 - Transfer Case
SHIFT MOTOR / DESCRIPTION
The shift motor (Fig. 90) consists of a permanent magnet D.C. motor with gear reduction to convert a high speed-low torque device into a low
speed-high torque device. The output of the device is coupled to a shaft, which internally moves the mode and range forks that change the transfer case
operating ranges. The motor is rated at 25 amps maximum at 72° F with 10 volts at the motor leads.
OPERATION
The transfer case shift motor responds to the Transfer Case Control Module (TCCM) commands to move the transfer case shift sector bi-directionally,
as required, to obtain the transfer case operating mode indicated by the instrument panel mounted selector switch.
