'05 CTS V Stability Control Warning - 4/28/2008 7:39:39 PM

I have a 2005 CTS V that was hit in the front and rebuilt. After the rebuild I get a warning on nav. screen saying service stabilty system. We had it looked at by a GM dealer and after they scanned it we were told the problem was either the yaw rate sensor under the center console or the Electronic Brake Control Module which is under the radiator in front of the motor. We replaced both and when I try to drive the stabilty system goes crazy. The brakes start grabing randomly until I let of the gas and the car stops moving.

I've ran out of ideas of what could be done to fix it. Any input anybody couple give will be greatly appreciated!

Thanks..

I'm not sure the exact code so I'll be taking it to the dealer tomorrow. I'll post what I find out as soon as I know.

We had 3 codes which we got while the yaw rate sensor was unplugged. The car runs and drives fine with that sensor unplugged. The codes were: C0186, C0187, C0196.
When we plug the yaw rate sensor in is when the stabilty system goes nut. The car never gave any codes anytime the stability system would act up. The thing we were thinking is something must be messed up with whatever computer controls the stability system...but we don't know which one that is?

The problem is the Stability Contol is acting erratic. So what controls the stability system? Is it the Electronic Brake Conrol Module (EBCM) is does it get comands from a different computer? And if its a different computer where is it located?!

Thanks for the help
