Wierd Brake problem ABS Traction control

[rodgerwilco1]

Ok, I will try to explain this and also have a question: Is it possible to have a sticky front brake caliper, and have that cause the ABS to kick in at slow/almost stopped speeds as well as cause the car to say the traction control is on or not working?

I have a problem where the traction control comes on or I get an error (Chimes and display lights up; no engine codes) or I get a "grinding" from the ABS being applied, but all at very slow speeds or even when backing up. I then usually get a Service traction control chime followed by a Service ABS chime and both lights come on on the dashboard. I thought it might be a cable to wheel sensor problem, but the wires seem to be ok (haven't replaced them yet). I was wondering if it could be a sticky caliper as the last time I did a brake job (beginning of the year) I notice the one caliper did not seem to want to compress smoothly (seemed to stick) when I compressed it to take it off.

I would get a scan tool that can read all 4 wheel speed sensors at the same time. It's fairly common from what I've dealt with to have 1 wheel speed sensor drop out to nothing at low speeds while the other 3 are still reading a mph. The computer see's this and applys the ABS thinking you are sliding.

As said, get it scanned. Sounds like a bad ABS wire/connector, or wheel bearing. ABS doesn't grind, so do your brakes grind when stopping?

I just fixed randomly pulsating ABS at low speeds; problem was the left front ABS harness, which an ABS scan tool pointed me too.

I've owned 3 '04+ Grand Prix's and what you're describing sounds like the wheel speed sensors failing. Happened on the first two I owned in the exact same way and I'm waiting for it to happen on my GT.
