I have a 2003 Chevy suburban that I can’t figure this service brake system everytime I hit a bump. The Vehicle Decelerates and sometimes randomly I lose all power and the battery system shows up. I have to cut the truck off and then on again in order to be able to go again and it restarts with no problems. When I hit bumps as well it unlocks and locks but doesn’t cut off at the time. It’s very strange. I’ve looked on YouTube and I cleaned all my grounds. I haven’t checked my ABS SENSORS yet but before I do I wanted to see what kind of advice anyone had for me on here first.

Without scanning all 4 code family's you and we are just guessing. Full code scan is a must. A good scan tool is more important than wrench's and sockets today.
