Just wanted to add some extra info to this thread because it seems that not all 95-99 Accent automobiles have the 16-pin ODB-II DLC connector which the information at the top of the thread applies to. When troubleshooting my 1995 Huyndai Accent 1.5 SOHC (12v - Automatic) I found instead a 12-pin connector. I also have a 1996 model and that one has the 16-pin connector.
I took a look at the service manuals which can be accessed at the
Hyundai Service Website. There a 12-pin connector is shown for the 1995 model:

As can be seen on the diagram, the 12-pin connector also has an L-wire (number 10) and Ground wire (number 12). By connecting them together in the same way as the instructions for the 16-pin connector tell, I was able to get a readout though the MIL (Check Engine light).
