I purchased my '96 850 Turbo last summer, and had the cost of the ABS module knocked off of the price. The dealer did confirm this was the problem but I held off on fixing it. Every day the ABS/Tracs lights would come on 5 minutes or so after starting the car. 1 week ago this changed. For whatever reason the light has not come on, and I have had a chance to test both the ABS and Traction Control, and they appear to be working perfectly. I really do not know why. 3 weeks ago I spliced a green wire near the radiator fan that looks to have been cut by the fan. I did not notice any ABS change immediatly after this. I put a couple of extra psi in the tires about a week ago (they were a little low). Maybe the best explination is that the temperatures have been in the 0's, and 10's lately. I seem to remember that cracks in the solder were to blame for these failures. Well I am crossing my fingers that it will work until the snow melts.
