STURNER Congratulations!  Your peers have given you enough reputation to put you into the fist level!

Default ABS / Stabilitrac / Brake lights

2009 Pontiac G8 6.0 ABS, Stabilitrac, and Brake lights are on. No codes. Good communication with module. When I enter ABS data all lights go out. I can toggle back and forth in and out of data and lights go on and off. No codes in any other modules. Im using an apollo. Im wondering if maybe a bad ground that is somehow finding a path through the scanner?

Stabilitrac lights with no codes in ABS usually means you'll find a code in a related system. If that's not the case, any chance a tuner has been playing with the car? If so, send it back to them to make it right.

That would be my bet.Might even be a ground issue inside the ABS module.

I have had weird issues with ABS if someone has replaced the brake light bulbs with LEDs,but commonly that will leave a fault code.
