C0374

Circuit Description
The transfer case shift control module senses rear to front slip, a difference of rear to front wheel speed and attempts to correct the difference by activating the encoder motor, to apply more torque to the front wheels.

Conditions for Setting the DTC
The transfer case shift control module is unable to correct sensed slip for 10 consecutive seconds.

Conditions for Clearing the DTC
^ A history DTC will clear after 100 consecutive ignition cycles without a fault present.
^ Use a scan tool in order to clear history and current DTCs.

Test Description
The numbers below refer to the step numbers on the diagnostic table.
2. Helps determine if the DTC set due to a mechanical or an electrical fault.
3. Tests the integrity of the Motor Feed circuit.
4. Determines whether the Encoder Motor is moving to the proper position.
