ABS/Brake light on dash
 

Hey guys, I had the ABS plug on the top of the rear diff unplugged while working on my truck and now when plugged back in, the lights on the dash won't go out. I've never had any trouble with this or anything else to do with the brakes in the six years I've owned the truck. Any help is greatly appreciated. Thanks, Matt

Take a peek in the sticky for info on how to pull the ABS codes. The codes will give you a place to start looking for the trouble.

Pulled plug back out of connector on the rear diff cleaned and gave it a good coating of dielectric grease turned key on and lights were still lit. Pulled +wire off of battery for the night and tried it this A.M. no more lights.
