OH NO!!! They should have called the silliy thing OBD III. Don't they know are lives are complicated enough with trying to figure out some of this mumbo jumbo
. When the bloody h*ll did they update OBD II???. Leave it to an engineer to make it 'Better'. Not to insult all engineers out there, just the one who made that decision. But I'm sure he has a perfectly reasonable explaination that would take two hours to read and six years to understand.
BOY!!! Oh well. We plod on.
