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.
Any help appreciated!
