    I'm pretty sure there is a pressure sensor that is faulty or the harness to it. Maybe one of the mechanics will chime in and tell you the specifics.

    Does your brake lights come on when your park brakes are on some do Mack etc. It would more then likely be a air pressure switch probably up under the dash should be at lest two switches, one for brake lights one for park brake light.

    Might want to have the dealer check the CECU for updates, we see issues like this show up and some times a re-flash of the CECU is the fix, also they can pull codes from it if need be.
