I have a 2012 GMC Sierra 2500 HD with 76k miles. I just replaced the two lower ball joints, idler arm and pitman arm yesterday. The only electrical that was unplugged in the process was the sensors on the hubs. They are reconnected and now, only when i slow down and turn my wheel to put the vehicle in reverse, the service stabilitrak sensor light and DIC come on. If i turn the truck off and then turn it back on, the light clears. Does anyone have any suggestions on what can be causing this? Thank you for any suggestions and help!
