Okay got the scan done today. It'* the "Electronic Brake Traction Control Module" it is not receiving the data all the time. The guy who scanned it is real decent guy and he said what he does instead of changing the whole unit he just replaces the computer part of the module, this way you don't have to deal with bleeding the brakes by not having to undo any brake lines.

Time is approx. 45 minuted to do. He has done a couple older Bonneville'* but not a 2000, he just finished a GM pick up and showed me the computer section of the module.

So it all makes sense now, as the very odd time over the last couple of years, when the brake petal was applied it would make the ABS sound but not vibrate

Where would I get a replacement without buying new, any suggestions?? Thanks

Still having problem inserting picture, I tried both jpeg and pdf formats, can anyone help me here also!

I have a 2001 bonne. I had it scanned and it spit out 2 codes....P0131 and P0442. I had my buddy use his scanner on it and it was claiming that there was nothing wrong with my car. He also said he tested the O2 sensor and it was at the proper voltage. Can you tell me where to look or what you think the problem is?

I've thrown a P0480 and I'm trying to resolve it, but I don't have a good pin out of the PCM connector.
