Can a bad TCCM be a bad encoder motor?
A bad TCCM could be the reason along with the encoder motor and the button pack. It is easy to diagnose the symptoms. There could be tons of components responsible for engine problems and the TCCM could be one of them.
What is the transfer case control module ( TCCM )?
The Transfer Case Control Module (TCCM) is a specialty of the General Motor’s 4WD operation.
What are the symptoms of a bad TCCM?
Transfer Case Control Module Symptoms Symptoms of a bad TCCM are likely to include flashing a warning message or turning on a warning light on the Driver Information Center (DIC). Apart from this obvious transfer case control module problem, you can look out for these following ones: The 4×4 System Stops Working
Where is the encoder on a GM 4×4?
That is not the 4×4 encoder. The encoder is on the transfer case and controls the shifting movement. The GM tech might have given you good information, but you replaced a part that has nothing to do with the encoder. That part will not fix the 4wd.
Is the transfer case encoder motor in neutral?
Here is my question: the truck is currently in 4WD and will not come out of it. Supposedly these new encoder motors are shipping in the neutral position. How can I a) get the transfer case into neutral manually, or b) get the new encoder motor into the neutral position manually.

What happens if the TCCM is not located?
If necessary, it may also trigger off the front differential locking actuator. If the shift is not possible, the selector switch will come on and flash for 30 seconds. Locating the TCCM is not tough.
