where is the diagnostic obd2 port on our cars? is it the ISO14230??

It's on the far left of the dash. Driverside, underneath.

It follows the ISO9141 Protocol

thanks man, so i ordered this Apexi I-moni.. it says ISO14230 diagnostic connection needed. I tried a 97 prelude, 06 altima, and a an 02 Rav 4. The unit won't turn on. What cars use a ISO14230 connection..

I know this is an old one but thought I'd try to resurrect it.
Does that mean that products designed for ISO14230 will not work with our cars? Has anyone tried a device with this connection?

I doubt it will work because it follows a different protocol (aka Standard, set of rules). The poster above tried it and it sounded like it didn't work for him.

I couldn't tell from this post as HKPISTOLE stated that different vehicles were tried and the unit didn't turn on for any. Sounds like a faulty I-moni.
I searched the web for ISO14230 and several cases turned up with ISO9141 within the same context. During the searches it was said that ISO14230-2 and ISO9141-2 both use the same pin out.
Here are a couple of links I came across.

This one I had to search the document.

I'm almost tempted to try it out. Maybe I'll see if I can find a place that will let me try one of these out.
