I just recently done a PST front end bushing replacement. Also I replaced the wheel bearings and inner seals. The brake pads are in excellant condition. Finally got my baby back togather and suddenly the ABS light stays on. Is there a way that I can find out what is causing the problem. How do I test the ABS to find any codes. I have a ODB2 scanner and it reads NO codes. Does anyone have a wiring diagram or test procedures for a 96 Impala SS ABS system. HELP!!!!
