It's more than that, it also defines a standard one or two wire serial bus 
that the ECM uses to communicate with sensors and other equipment (including 
diagnostic equipment), and a standard for the information packets that are 
placed on the bus.  So one diagnostic computer will work for all cars.  This 
would indeed be a good feature to include on a diy-efi computer.
