    disconnect the pigtail from the tractor, see if it still happens.

    I’ve tried that already. The tractor abs light stays on. I replaced the pigtail recently because my trailer abs light was coming on due to a bad connection.

    I’ve been through all the relays and fuses. Haven’t found a test switch yet.Next will be wires and sensors. I really wanna know what that fault is, I’ve searched online for it but haven’t found anything helpful

    That's what I was going to suggest,:laughing-guffaw:They don't call it a-BS light for nothing.

    Man the Freightliners we had at my last outfit looked like Xmas trees sometimes.
    Usually if the truck was running ok I just ignored em.
