It isn’t just one module. That’s what I’m trying to tell you. There’s a handshake. So replacing the Electronics control module or the Powertrain control module those modules have to be configured to the Vin. In my mother’s escape the PCM is in the wheel well behind a liner held in by plastic clips. None of those parts can be replaced without being configured to the VIN.
I know that it isn’t just one module. What is the handshake achieving exactly? Because it’s not additional security from an attacker trying to replace the keyless entry module with a hacked one, and if it is doing that then this is a terrible security design and the actual solution is not to get to keep using this ‘security’ threat model.
