My service stabiltrak and service traction control lights come on immediately from the time the car starts.....The ABS light is not lit up on the dash at this time nor have i even seen it light up...I have ran a diagnostic tool on it with results being C056D-00 which says Electronics Control Unit Hardware, stored in history and currently active as well...It has intermittently displayed Circuit Pump-Stuck as well which usually clears....These lights are driving me crazy and i would like my abs fixed asap....I have checked for bad grounds, checked the wheel speed sensor wiring, cleaned all 4 wheel bearings and wheel speed sensors and checked for vacuum leaks as well....Can someone please help me diagnose this before I go crazy lol.....Thanks
