    2003 cm845

    Truck was tuned with an Edge programmer of some sort.

    Couldn't return it to stock.

    "Read" the stock file, modified the stock file, and now when I flash I get "Controller Unlocker: Timed Out". I did license the controller.

    Truck won't start and my SnapOn Solus Edge cannot connect to the ECM.

    What do I need to do?

    Well, I decided to try the old trick of disconnecting the batteries. Let the truck sit for about 30 minutes with the ground wires off and then I was able to flash the ECM.
