    Default E39 - 'Unrecognized PCM' error with 2012 Chevy Traverse

    Just picked up a Traverse. Did a readoff with V8. Opened with V7.5 and I get an 'unrecognized PCM' error. What's the next step? I need access to the tables and all it will give me is the OS/cal numbers. I'm trying to find a spare ECM to swap in but don't want to waste the money on one if I can't talk to it.

    OS & Cal: 12648907

    12648907 is definitely supported in the latest build.
    I no longer monitor the forum, please either post your question or create a support ticket.
