I've been dealing with this since last week now. Had the gauges go a bit whacky when driving and a few weird service messages.
When I got home and went to start again later, Tahoe wouldn't start.
I disconnected the battery and reconnected.
Now, the dash icons illuminate, there is no start to the vehicle, and I get several service messages.
Service Airbag, Suspension System, Trailer Brake System, Front Camera, Theft Deterrent System, Tire Monitor System, Park Assist System, Side Detection System
From my investigating, I'm showing 11.9-12V on battery and no DTCs from scan tool.
This is a snapshot of while I was driving last week and the fist time gauges "acted up."
I've got the following on the list to be checked into, trying to get a tow into the Chevy dealer today.
1) new battery needed?
2) negative cable harness
3) battery grounded properly near vehicle frame - corrosion?
4) new BCM
5) OBD2 bypass kit for MRC delete? Passive battery drain or other corruption to ECM/BCM? - phone call to Xineering techs; they say there should be no correlation between their OBD/SS MRC delete product and my current experiences. That there product has a RAF that will not allow parasitic drain from the battery.
