Why does the antiloc brake pump or motor keep running even with key off?

well if you reall think that we can diagnose something that keeps running and have no way to physically inspect it then that is the answer you 'll get. Otherwise you can buy a new unit at aobut $800 plus install, get a used one out of ajunkyard ro take that out and get it rebuilt to replace the transistor that goes bad because it's not large enough and have your car hung up for several weeks.
