I believe that OBD-II (On-Board Diagnostics version 2) plugs became standard on all North American vehicles, including Toyotas, by 1996. But right now I'm in a country which receives a lot of used right-hand drive Japanese-market vehicles. I'm noticing that some of these cars even from as late as 1998 didn't have any OBD plugs. Any idea when OBD plugs became standard for the Japanese market?
I'm sure that the Japanese version of OBD-II would be called JOBD or something, but it'll likely be compatible anyways.
