I was wondering whether the electronic interface to the ECM was an OBD11(2) compatible one, or just an exclusive to hyundai. I found on scantools.net that there is open source software to interface to most American delivered cars post 1996 (hyundai included) but the connector is in a different place and looks a little different and maybe this was an older style. Also troublecodes.net had some information. I might add Australian delivery and compliance, right hand drive! Any help appreciated!
