If you have a '96/'97/'98, could you look at your 16-pin OBD-II port on the car and let me know which terminals are populated? And the wire colors? Thanks!

If you have a '96/'97/'98 SM/ETM or access to them, could you look up in the SM Engine Electrical Systems section Cruise Control subsection and post a copy of the page with the DLC illustration on it and the page that says Self-Diagnosis Checking?

And, could you post a copy of the ETM Cruise Control schematic and the Engine Control System schematic (they may have still been naming it DOHC System - not sure when they changed the name), and also post the ABS schematic? Thanks!

Still looking for anyone with a '96, '97, or '98 Elantra who could help with some checks on their OBD-II port.


On the SMs/ETMs portion of the original post, I no longer need those.

I have obtained every (gen 1 and) gen 2 U.S. Elantra SM/ETM from ('91-'95 and) '96-'99, and have gone through all of them.

Pic of those manuals is in this companion post.

Still looking for anyone with a '96, '97, or '98 Elantra who can help with some quick checks on their OBD-II connector, the 16-pin DLC port.

Looking for multi-meter voltage on:

DLC pin 15 and ground, ignition on.

DLC pin 7 and ground, ignition on.

DLC pin 1 and ground, ignition on

DLC pin 9 and ground, ignition on


And, IF DLC terminal 11 is populated? And what color wire? (Don't check the V here, just eyeball the terminal and wiring.)

And the production date and month on the driver's door jamb?
And, if ABS is installed?
And, if Cruise control is installed?

If you multi-meter-check DLC pin 16 and ground first (key out is fine), that will help confirm the other readings, once ignition is then turned on for them.

This pic helps in ensuring you're on the correct pin.

For ground, it is easier if you just run a gator from the multi-meter's black lead to the driver's front door middle-hinge bolt head (that is on the same plane as the OBD port). The d's door jamb special phillips head also works great as a gator ground point. This way, with the gator, there is no need to fumble with trying to touch both m-m leads on the DLC. You can just touch the m-m red lead on the pin of interest (since the gator will provide the ground, without having to touch the m-m black lead to pin 4 or 5).
