How does the VATs relearn work? Does the ECM get a "Password" from the BCM, thus allowing the engine to start, the BCM get a "Password" from the ECM, or do they make up a "Password" and share it between them?

BCM has the master password, the ECM 'learns' the password.
I no longer monitor the forum, please either post your question or create a support ticket.
Then is it possible for more than one ECM to be married to the BCM so if swapped out, they won't have to be relinked?
You can disable the security {G1201} Anti Theft Configuration.
