I need help guys. I am experiencing the dreaded ABS and traction control warning lights. I am finding tons of info on 2001-2004 models, but having a hard time finding info about my 1999. I believe the problem is a bad ground or connection, because it only happens when I hit a bump or pot hole while at cruising speed. I have braked hard on gravel, just to acitvate the ABS and it works fine, so that's why I believe the problem to be a bad connection. Does anyone have any pictures of where the EBCM is on my 99 and where it grounds to, that has caused people the most problems in the past? Any help is much appreciated.
Definetly check first for codes, I have a 99 and am betting its a wheel sensor and the codes will tell you which one. Anyway, thats what it was on my 99 when the light show happens after a bump and the car looses ground traction.
Check the cable and connector to the LF wheel. It may be damaged or loose. Check the routing of the wire to the sensor. It may be too close to spark plug wires or the coils that could induce voltage variations.
Yep, I took the wheel off, checked and cleaned the connection and that was it. I think if you just check and clean it and put it back on, and then see if it throws codes again. IF it does, you may need more than just a cleaning. IF it doesn't throw codes then you know that was it. Good luck, let us know how it turns out for you.
