Really? Well that's promising.
I agree with your that it needs to enable anything that's required for "repair" of the car. Examples:
- Tesla wouldn't sell me a 12V battery because the newer model requires that the car configuration be changed to reflect a newer replacement battery model
- I have a repaired charger sitting on my shelf I can't reinstall, because when it died I didn't know it was repairable (just a blown fuse actually), and had my car converted by the service center to a single-charger car. They won't re-install a repaired charger, and I don't have the tools to reconfigure it.
- Somebody online just posted they scored some fog-lights from a salvage. Despite being installed, they can't tell the car configuration that, so they have no way of being turned on.
- In order to do a basic coolant air purge, you need to command the pumps/valves for specific action
There are a myriad more... I have a service manual for the car, but can't accomplish a myriad of the procedures, not because of mechanical issues, but because of computer configuration issues. And none of those are exotic or involve the high-voltage stuff...
