    When you disabled PATS, which VIN/Strategy did you disable it for? The one for the car, or the one from the ECM you put in the car? Try pulling the out by doing a "read entire" and then see if it prompts you to license it again.

    Sometime ago Eric told that the switch is there but it doesn't really disable PATS. They are going to add the functionality to the software but who knows when.
    You need to take the car to the dealer and reprogram it.
