I'm pretty sure you are correct. When I was in mechanic school they taught us about gasoline EFI with OBDII. On an OBDII system the light is required to go on when something emission related has gone out of set limits. I believe manufacturers are also allowed to have it go off in the even of other things related to out of limit engine performance. On a pre OBDII system, who knows? They didn't really cover that in school. I do know that OBDII standardized certain codes (but unfortunately not all, hence proprietary diagnostic software) and the method of extracting them. Things were more varied before OBDII.
