OBD II Location


Recommended Posts

For 1988-1995 models, the ECM is located under the right hand side of the instrument panel.

 

For 1996-2000 models, the PCM is mounted to the left inner fender under the hood:

That is what I thought, Just wanted ot make sure.

 

 

 

 

 

I'm lost. The old body style (OBS 96-00) has a PCM, so I don't get it.

 

When it comes to the comment about the PCM and the follow-up about it being a "good one" I think I'm missing something. At the risk of sounding ignorant, can you "clue" me in, 'cause I don't get it.

So what cable are you using ?

 

Do you have a serial cable 9-pin -to- OBDII connector?

 

What software are you using?

 

What year vehicle the 2004 with the class 2 communication or the new GM VLan?

 

Just curious as I'd like to do this myself...might consider the autotap but wondering how you plan on doing it...
