While replacing a broken wheel stud (driver's side front) on my girlfriend's 2005 Chevy Cobalt, I had to unplug the ABS wiring located above the spindle so I could pull out the hub. I plugged the two ends back together after putting the hub back in place, but now the ABS light on the dash panel is lit. She is pretty sure it wasn't on before I did the work, so I was wondering if a temporary lighting of the light is normal after the unpluggling. If so, can I take it to the dealer to have them remove the code and reset the system? If it doesn't seem normal, then what could be the problem if the wiring, at least on its exterior, appears undamaged? Could I have caused it?

The sensor is part of the wheel bearing and hub if the wire OK and its plugged back in I would suspect that the sensor was damaged when the hub was removed try and drive it around if the light go out you r good if not need to have it scanned for codes let me know what you have for codes I would suspect a bad wheel sensor since u had no light until hub was removed
