    2006 chevy trailblazer no communication

    hi, I have a verdict d7 system and I was wondering if anyone else has been experiencing no communication issues with there system as well, I tried everything I possibly could on this trailblazer to scan it, no luck.
    I tried changing the year from 2001 to 2009 nothing, I tried obd direct nothing, I called snap-on tech support and got nowhere, they told me it must be the vehicle, but that is not the case because when I hooked up a cheap launch obd2 scanner it worked fine, but verdict still don't work on it, biggest problem is this vehicle has an evap issue that I cannot test because I cannot operate the vent or purge valve for smoke testing, any ideas, anybody?

    as far as I am concerned I should not have to have 2 scanners, one being just to check to see if the vehicle is the problem or my 8000.00 dollar scanner, at this point I consider this tool undependable and unreliable.
    thanks
