Rule #1 of Tuning bud: Never turn the key off in the middle of a flash.
We've all made that mistake before... some of us more than once. hahaha
Fords for whatever reason can be especially finicky.
You have to be exceptionally cautious when flashing Fords.
The PCM has been erased, and the reflash was not completed. There isn't ANY data on the PCM.
The PATS system cannot communicate with it, so it throws the vehicle into theft recovery mode.
The PCM needs to be flashed to stock with IDS or FJDS. If you have a J2534 pass through cable like the one from TACTRIX you can use that to recover your PCM with a $50 72 hour licence from motorcraftservice.com.
After the PCM is reflashed, the PATS system needs to be reset. It basically needs to be told that there is a new PCM. It takes 10-12 min just access this screen and an additional 5-6min to complete the reprogramming of the PATS system.
