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

Installing the latest build now. Should take care of it according to another post.
