Hello! May be some one know what the problem. I tried several cars like Hummer H3 2006 and so on, when I connect MPVI2 and try to read it tries about 5-7 minutes and then show message timmed out. But If I connect MPVI 1 to the same car it read it well. But much longer time, but read. With another cars Like Escalade 2007 MPVI 2 works good.
