On-board diagnosic info, pls.

Can someone point me to the On-board Diagnostic codes, please. And, actually, an overview of how to use the OBD would prove useful, too. :)

( I've a '90 Ram 50 2.4L )

Thanks!

Well I don't think anyone has a true wright up with step by step yet.
But it takes a volt meter and a jumper wire / paper clip.
I know it's described in the manual on how to pull the codes and also a list of codes.
The manual is in the manual section > over 216 manuals > montero it covers your truck It's like the 4th one down.

Its a 94 truck here but it will give you a better idea on how.

Thank you very much, camoit!

Thank you very much, Rickdees!

Oh you must you a meter with a needle on it. Otherwise you won't get the code correctly.

Thank you again, camoit! Appreciate the time you've taken. :)
