2008 LMM T case Encoder motor is working as it will go into low range, No indicator light in the dash though (suspect the TCCM from the reading I've done) I have no voltage at the plug on the diff actuator, TREC fuse is good and Lights on the dash knob work as normal, I can hear the T case doing its thing when shifted. but with a Fluke meter I have no volts at any of the 5 pins on the diff actuator with the key on. thius T case also DOES NOT have the t-case switch. from the reading i have done it says the TCCM could be bad if the 4wd indicator in the dash doesn't light up when the t case is in 4hi or 4lo which this truck is not lighting it up even with a scan tool. I have a LMM across town I can go rob the TCCM out of and see if that is the issue. any other ideas?
