It appears that my ABS Module has been faulty and by perusing this board I was able to contact Victor Rocha here in Southern California. I wanted to thank Vic for helping me out and giving me a very reasonable price compared to the local Volvo dealers and independant service centers in the area. And he was just over the hill about 5 miles away from my home. Vic was very personable and let me tell you, he knows his Volvo's! Being not very mechanically inclined he was able replace the module and put a refurbished one in very quickly. He also diagnosed a future problem I have with my motor mount. Thanks again Vic!
