Just had the opportunity to go to an ATG course in King of Prussia, PA, for a training seminar hosted by Ross Wellwood on body control modules/computers!!!! DO NOT MISS THIS SCHOOL!!!!!!!! It is (in 2 nites) one of the MOST informative, well thought out, info on the domestic big 3’s theory and diagnosis to body control networks. I would have to rate it AAA+++++ - Mike P.
