There are several bulletins regarding transfer case faults. Everything from the encoder sensor to reprogramming of the TCCM is mentioned. It may not be either issue, you don't know at this point. The best advice would be to have the diagnostic codes read. This will give you a more defined direction. If the transfer case control module needs calibration upgrade, it will need to be done by a dealer terminal.
