Thanks for quick reply

Is the ECM still talking to the scan tool?
If it isn't then you need to send it for a repair service. Sometimes it takes several attempts and they accept a flash, sometimes they are just fubared.

Ill check it in the morning and see if it will communicate. Mechanic is blaming GM saying their site gave him a bad download. I doubt it
