I finally found a code reader that is only $92, not $499, that will read the ABS and vehicle specific codes. I am getting Shuttle valve switch electrical failure and Right Rear Outlet Valve open Circuit. I have replaced the shuttle valve. I am assuming it needs the new ground wire mod since the new valve did not work? I have no clue on the RR Outlet thing. Anyone have any guesses? This is on a '03 DII. Also I am only having intermittent three amigos. Some drives it never comes on and others it does about halfway through.
Thanks,
Eric

 

Maybe option B is something to consider

 

I second the option b advise. But look at my post about my issues. It can be much easier than it seems at first flush.
