    I have a 2007 379 and occasionally my ABS light comes on. Some days it is off all day and others it is on all day. I have seen it go from off to on or on to off when I go over train tracks or rough spots in the road. It must be something loose somewhere but I am unsure where to look. Any ideas on how to figure out what is wrong?

    Check your sensors on drives. And the connection on the frame rail. Just follow the wire checking each plug.
