I searched and thought that this thread would be helpful.

Apparently this truck has a transfer case control module (TCCM), but for the life of me I cannot find the ******* thing. I dropped the glove box door down and popped the passenger side kick panel and there's no sign of anything other than HVAC in there. I also tried pulling tcase codes by grounding pin 13 of the OBDII connector and when I turned the key on I got absolutely no sign of life. I really don't want to load the parts cannon but I'm running out of ideas on how to smartly troubleshoot this thing. At the moment I've had the fuses pulled for almost 30 minutes for 4WD and hoping I get something from the switch panel after the 5 key cycles to reset the TCCM.
