Time for a story. I have had my Roush for almost 2 years now. The ABS light has always been on. The previous owner had replaced the module (had a work order and invoice) with a refurbished unit, which does say Mustang GT. It's made by Bosch. All fuses are good. When I first got the car, sometimes ABS would work if I unplugged the battery. I would also get my traction control back. After a short drive however, I would lose both. Currently, I always have the ABS light on. The traction control button isn't illuminated. I have cleaned all 4 wheels sensors. I have also have tried to sue 2 different code readers, both with the same problem. The code reader can't read the ABS code. Is my abs module bad? Or have i overlooked something else.
