While driving home today the TCS, ABS and BRAKE light were flickering off and on, with the "Chime" at the same time. I didn’t see anything in the DIC. The once I got home, they stayed on! I hooked up my scanner to see if any codes would come up and it said “no codes.” Is anyone familiar with this?

Typical OBD2 scanners will not read ABS codes. You would have to get that scanned separately.

Although, this sounds more like a short in a wire, or possibly a fuse somewhere. Someone who has worked on this car should be able to give you a better answer.

Welcome to GMForum by the way.

Sounds like a wheel speed sensor

Go to the techinfo/testing area. I just did a write up on testing wheel spin sensors. It can be done easy with a digital volt meter. But right now it sounds liek a wet or corroded WSS plug, or a WSS starting to go out. This will also happen if they over heat.

Thanks for the advice guys...
