Engine does not start crank due to BECM, probably

[Daniil]

Hello everyone, I'm new to this forum and a week ago I received a flooded Ford F150 3.5 Powerboost supercrew 2021. The water was a couple of inches above the floor, I immediately looked at the BCM in the passenger's feet and it was in very bad condition, I bought a new one from the same Ford model, re-soldered some connectors, connected everything, everything turned on. I also replaced the starter because it had become unusable, I also tried to supply power to the starter and it turned the engine without any problems. Then I called a person who helped me to bind the keys to the new unit and connect all the systems with new BCM, the engine started only once after many many attempts, we think that there is an assumption that the VIN number is incorrectly flashed into the BECM, but it is not possible to flash the right one. Maybe someone has encountered this? Below are several screenshots of the units. I will be grateful for any explanation or help. Thank you!

I'm guessing that FDRS has some routine available for VIN marriage?

BCM,PCM you will need a dealer login or NASTF to do a parameter reset, that will also fix any PATS and VIN mismatch problems.

So this person he helped me to connect all modules together and as I wrote it started, but only once, I’m not sure that there are any issues with pats, because all keys works properly, or I do not understand something correctly

Keys can be programmed and still need to do a parameter reset. It happened to me on a 2020 f150 all keys worked but it would not start.Had to get an Autel km100 and do the reset

Okay, thanks, I’ll tell this information to my person, but I assume that he already did some reset, not sure
