OBD-II diagnostics are mandated by law, but manufactures often connect almost all microcontrollers to that connector. This allows updating all of your firmware from one port. That can be a security problem when connected to the internet.
- nickbauman 10y agoI was not aware of this; I assumed it was read-only except for reset flags, thank you for pointing this out.
