    Re-read the file off the car. This happened to me while working on my friend's 2005 Corvette, and re-reading the file fixed it.

    Scanner works fine. Cant load new tune. Can't get past Preparing VCM---- FAILED
    Also noticed CABLE STATUS shown at bottom of screen in VCM Editor reads NOT CONNECTED
    How would the scanner work with the same cable?

    This happens with my CTS-V every once in a while, I disconnect the scanner, go key off for 30 seconds, go key on for 30 seconds and do a write entire, fixes it every time.

    This is the first time to have this problem with more than a hundred flash, write calibration only, files. Same vehicle. Done some searches and found where after market radio, alarms, remotes, etc. could present some problems.
    I had my remote entry, door lock actuactor switch replaced today.
    Could or how would this affect VCM Editor?
