I?ve been having some issues with my 02 Avalanche 2500 it has 191,000. For some time now my ABS and brake light would come on after driving for a little while and stay on for the rest of the day and sometimes for the next day. The truck would drive and brake just fine but the light would be on. This has lasted for months I?ve just let it go. But today halfway through my drive home the ABS light started flashing and beeping! It wouldn?t stop until I came to a stoplight then it finally stopped beeping until I started driving again then it was back. I?ve read a few posts on here about the ABS module going bad could this be my issue? I don?t have a scanner so I can?t find out what code it is throwing. Has Anyone had similar issues or have any suggestions? I?ll take them all lol
