How to relearn a procedure on a GMC after changing?
Without resyncing, the PCM cannot properly determine the position of the crankshaft. The proper procedure for resyncing or relearning the crankshaft position is called the “CKP Variation Learn.”
Why is my transfer case motor not working?
If there are any issues with the rotational position sensor (RPS), incremental position sensor (IPS), encoder motor, motor A or B circuits, RPS or IPS circuits when the transfer case control module attempts to determine location the location cannot be determined correctly.
How does the transfer case encoder motor work?
The transfer case encoder motor is a bi-directional DC motor. When energized through motor control A or motor control B, the ground connection is provided by the opposing motor control circuit, which is then grounded through the transfer case control module (TCCM) ground circuit.

Why do I have to relearn the crank on my GMC Truck?
The reason for the relearn is for the missfire detection to be accurate. It is something that has to be done when useing a pcm that was not in your truck previously and had the case learn done on it. Even from the factory, each vehicle has to get this done to the computer/ motor it works with.

The following diagnosis might be helpful if the vehicle exhibits the symptom (s) described in this PI. Some technicians may notice that the vehicle has a C0569 System Configuration Error that will not clear. The vehicle may have had other transfer case related diagnostic trouble codes when it arrived and a repair made.
