Hello All,

I hope I am giving something back to all who have helped me in the past. I have a 1996 850 GLT wagon. Several years ago the "TRACS" and "ABS" lights came on. I sent the ABS unit to to Victor Rocha out in Rowlands Heights, CA to fix. I got the unit back and installed it. For 4 years I had absolutely no problems and suddenly "TRACS" and "ABS" lights came back on. I contacted Victor and he said the problem may be due to dirty ABS sensors in the individual wheels. The problem was the "TRACS" and "ABS" lights would come on once a year, and as soon as I turned off the engine, the lights cleared. Also the lights would come on spontaneously without me even applying the brakes. I could never get the car to my independent mechanic with the lights on so he could hook up a scanner. About a week ago, I was finally able to bring my car in with the "TRACS" and "ABS" lights on so a scanner could be hooked up. My mechanic confirmed the problem was not with the ABS unit, but instead a defective Brake Pressure Switch (EBD Pressure Sensor) - Part # 9173210.

So at last the problem is fixed. I hope this information is helpful to others. Thank you all for helping me in the past when I posted questions.
