I'm sorry if this ask already been asked in the past.
On my 20005 H2 the ABS, Parking Brake, and TC lights come on intermittently while driving. If I turn truck off and restart it the warning lights are gone. I recently had work done on the front end including new rotors but I went several months before the issue started. I have tried to catch a code with my scanner but there's never a code. Does anyone have an idea what would cause this behavior?

 

Welcome to HF. MOVED this to the H2 section, where all H2 Tech Questions go.

What kind of scanner are you using? A simple OBDII code reader cannot scan ABS Modules, you need an ABS capable scanner.
