    So, I have a 2003 Kenworth T600 and the ABS light comes on the instrument cluster. I checked the relays and I was at a TA and had them look over. We couldn't find anything obvious.

    About 2 months ago there was a code that came up for ABS but NOTHING since then. The code from way back then was this:
    Brakes, Power Unit
    Relay Diagonal 1
    Voltage below normal or shorted low MID 136 SID 14 FMI 4 (even though the ABS light is on still on now)

    FMI 4 means different things depending on whether you have Bendix / Eaton / Wabco. How do I know which I have on this 2003?

    FMI 4 for Bendix & Eaton it means "Common Side of Valves - Shorted to Ground" What exactly does that mean?

    Means you have a short in the wiring. Talk to a dealer, they can pull up the specs for your truck with the VIN and tell you what system it has
