On Board Diagnostics 2 – The newest generation of diagnostic port. All auto manufacturers use this standardised system to communicate with the vehicle. The plug interface is the same for each vehicle as well as the communication protocols. It allows one standardised system to work with all cars. Previous generation OBD1 was not standardised and proved to be insufficient and is no longer used.
