Is anyone aware of where this may be located? I have a 96 Suzuki Every Joypop 2WD Turbo van. This is a schematic from the AT EFI version, and although mine is MT its EFI.
These ports use a special Suzuki OBD-ish reader, which in turn utilizes various slide-in cards depending on the exact model and year of the vehicle. I haven't yet found an adapter that works with a standard OBD-II reader. The original readers come up for sale here in Japan often... usually a few hundred bucks and of course, finding the correct interface card. Experience says that a "Check Engine" light means you need a new O2 sensor. Regards,
