Can a bad TCCM be a bad encoder motor?
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 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
What is the transfer case control module ( TCCM )?
The Transfer Case Control Module (TCCM) is a specialty of the General Motor’s 4WD operation.
How does the TCCM control the lock up?
The TCCM is the component that commands the lock up, but for some reason it has noticed a failure somewhere and it’s trying to show you what the fault is by blinking the light. That’s the point where the module needs to be scanned to see what it is.

What kind of reference signal does TCCM provide?
The TCCM provides a 5-volt reference signal and a low reference circuit (like a ground but with a set voltage drop). It receives the motor position signal on the encoder signal circuit. The following circuit tests apply to these vehicles: Disconnect the electrical connector at the transfer case.
How does the TCCM work on a c0327 4WD?
The transfer case motor mounts to the transfer case and engages with the transfer case sector shaft. The TCCM provides a 5-volt reference signal and a low reference circuit (like a ground but with a set voltage drop).
