DTC Descriptor

DTC C0569 4B

- System Configuration Error Calibration Not Learned

Circuit/System Description

* This is an internal fault detection of the transfer case shift control module (TCCM). No external circuits are involved.

* This DTC is set anytime a TCCM is replaced or reprogrammed.

* The automatic transfer case (ATC) motor learn procedure must be performed to erase this DTC. The motor learn procedure allows the

module to learn where the shift rails are located.

Conditions for Running the DTC

* Ignition ON.

* System voltage 10.5-18 V.

Conditions for Setting the DTC

The ATC motor learn procedure for a new or reprogrammed TCCM has not been performed.

Action Taken When the DTC Sets

* The SERVICE 4WD indicator illuminates.

* No mode position LED's illuminated.

Conditions for Clearing the DTC

The TCCM clears the DTC once the ATC motor learn procedure has been successfully performed.
