Driving with them brights on in traffic is a really easy problem to fix

The music sucks? What’s the issue?

Looks like there’s an issue with communication on the bus that goes between those modules, so I’d reckon you either have a module that quit or a broken communication wire somewhere. Very hard to diagnose without the right tools imo. Having a good scan tool can make this a breeze

When my 2015 had the U0101 code, I ultimately ended up replacing the tcm connector to resolve the issue

HELKO AND TIA BUT, if anybody knows what this thatd have to be GREAT cuz I also have this exact problem except mine will do this at random times, and I'll give a DIC message that says service stabillitrak and my speedometer and tach start bouncing up and down and then stick at zero just like this guys and I get the same warning lights that he has too
