However, one tire (Pass Rear) would go from 35 to 37 psi and would not stay at 36. So I held in the turn signal button used to reset many things like MPG, Fuel Range, ect. When I did this, and I won't swear to the order, the DIC asked something like "do you really want to do this". I chose yes, and then the car honked. I do not remember how many times it honked and I didn't look at the trurn signal lights. While thinking, crap, I screwed something up and now would have to go look for the relearn procedure, the DIC screen returned to the tire psi screen. It was probably about two to five minutes. Now I'm no expert, but this sounds as though I put it in the relearn mode? Does this make sense to anyone? Maybe tonight I'll mess with it again.

I'm guessing you started the relearn process and it timed out. To do a successful relearn you have to do something to tell your car which sensor is in which wheel. The old way was to let pressure out. That used to work. Never has there been a way for it to actually do a relearn without the tire pressure drop or the tool. Several people on this forum and other forums for other GMs have tried the tire pressure drop and it hasn't worked with the newest cars. The dealerships and Chevy customer care confirmed this. Several people with earlier 11's have had the tire pressure drop work. Hitting relearn, doing nothing, and then not having an error doesn't mean it did a successful relearn of the sensor positions.
