I guess I should have clarified, I checked the rear ABS module to the best of my ability. I disconnected it and checked the resistance, it was around 1750, which I read is good. I also cleaned it. I'm not really able to do any spinning wheel tests. I'd like to check the rear brakes to make sure a spring hasn't broke or something. But the last time I took it in they tightened the lugs so tight with an air wrench, I can't even get them off. I'll have to try again or take it in. The ABS are kicking in on dry pavement. ABS over activation I think they call it. After reading things, sounds like it could be a wheel speed sensor. Not sure how to check these, so I don't totally get taken.
