What is the purpose of an electronic shift motor in a transfer case?
But something has to be responsible for moving the internal shift levers that make that happen. That is the role of the transfer case shift motor. It powers the mechanism that causes the inner workings of the transfer case to engage your 4-wheel-drive.
How does shifting occur in the transfer case?
Shifting in the transfer case occurs when the shift motor brake is released and a Pulse Width Modulated (PWM) voltage is supplied to the shift motor by the Front Control Module (FCM). A linear analog position sensor located inside the shift motor, provides the FCM with the motors’ angular, rotational position. With this information, the FCM
When do you need a transfer case motor?
The transfer case motor is a small, electric motor that moves parts within the transfer case to trigger different modes of the 4WD system. If you notice that you are unable to shift in or out of 4WD, or your service four-wheel drive light is on, you may need to check if your transfer case motor needs to be replaced.
How does the transfer case work in a car?
The operating current of the shift motor under Shifting in the transfer case occurs when the shift motor brake is released and a Pulse Width Modulated (PWM) voltage is supplied to the shift motor by the Front Control Module (FCM).
Is there any way to test the transfer case?
If a new shift motor assembly must be installed, it will be necessary to shift the transfer case to the AWD position prior to motor installation. Raise the vehicle on a suitable hoist.Remove the front propeller shaft.
What causes the transfer case to fail on a Dodge Dakota?
It has been known to shift to 4Lo without warning, at any speed, and whether the vehicle is on or off. If this occurs at highway speeds, the result can be catastrophic failure of the transfer case. This is caused by a faulty four wheel drive shift motor, selector switch (in the cab) or the wiring between the two.

What should I do if my transfer case motor failed?
To correct the issue, inspect the wiring to the transfer case switch motor for damage, and replace the shift motor if needed. Disconnecting power to the shift motor will lock the transfer case in its current setting. The average cost for a Dodge Dakota General Diagnosis is between $88 -$111.
Why is my transfer case switch not working?
The most common cause is the transfer case switch, which is an electric motor mounted on the transfer case. To correct the issue, inspect the wiring to the transfer case switch motor for damage, and replace the shift motor if needed. Disconnecting power to the shift motor will lock the transfer case in its current setting.
