Chevy equinox 2008 140kmiles awd sport
U0102
How do I test the tccm what components can cuase this besides the computer i cant find alot of information on this car online and is my first time diagnosis a awd drive problem does the awd have a sensor on the case or does the tccm get all of its information from the transmission speed sensor wheel sensors I hear some are different and I didnt see any wires around the base.
I would start by checking all the ground wires and then using a test light to check all fuses.
try unplugging and plugging the TCCM connector back in. Make sure there isn't corrosion on it and the wires are in good shape.
This was the first Google results. Excellent troubleshooting info there

I've looked thru the repair manual and it doesnt have anything on a tccm moduler how do I find it
OK I did some research, and the Equinox AWD system has no electronics. The PTU and the RDM are completely mechanical. There is no TCCM.
The Equinox should not ever get code U0102. Are you sure it's correct?
