All in ecm programming. To make what the other modules see for “keys” match.
I tried many times can never get the key to work could you help how make it turn on ? 19-21 ecm on a 22
We tried with Witech and the secret code straight from dealer, same shit wont start
I have 3 19-21 that lose the VIN when installed on the truck. VIN shows all 0's. We try to update the VIN with EFI and shows it was complete but when we double check it, it still shows as all 0's. Hoping we can get this figured out. Do the keys need to be relearned into the new ECM?

I believe the "secret code" cant be obtained from the dealer anymore. Have to have a NAFTA ID to be able to program keys/codes. Ran into it when programming a replacement PCM on a flood truck.
