Traction contol/ABS light 2000 GM
When this first started happening, the car would go into "limp mode". Sometimes, if you hit a hard bump or rumble strips on the road, the light would come on and you were creeping along. Sometimes after that happened you could hit the rumble strips again and it would go back to normal. There is a reset button in the glove box, but now does nothing. This time, after mom had new tires mounted the light came on and stayed, but the car still runs fine. Would this be a bad sensor, and if so where is that sensor located? If the reset button is not working is that a sensor or is there a relay of some type? I would assume this is the same sensor for the ABS too, so is there one on each rear wheel? The local Ford dealer has not been able to find a problem, even drove the car but couldn't replicate the issue. I do know that she has some warped rotor and it feels like the fronts, but this was an issue before the brakes. I have not worked on this car, it has always been dealer serviced (it was my fathers and mom kept it after he died) that's what bothers me. I know dealers can't work miracles, it just seems with todays electronics, that would not be that big of an issue. Would that not kick a code? What about removing the negative cable and holding the brake pedal for 30 seconds to clear the computer or just unhooking both battery cables?
