What Language does a 92-3.8 speak

I would like to know what language the PCM and ABS speaks, is it ODB1 or ODB2, Is there any lists of codes avaible anywhere.

OBD I . Here is a link I have found useful in the past that can give you some more info:http://www.geocities.com/dann8785/serviceenginesoon.html

Ok then, is there any description on the various codes to read and to send.
Reading the workshop manual, there seems to be possible to get live data as well.

Check this out:
www.avigex.ca/xport/readingcodes.jpg and www.avigex.ca/xport/3800codes.jpg
Then check this www.avigex.ca/xport/index.doc for a lot of pages most of them scanned from the '93 transport manual; one difference with the '92: yours probably does not have an EGR valve.

Ok, got that, but what I really want to do is to tap into the serial line, otherwise I cant get the ABS-codes nor do the various tests, I guess.

There once was a very talented german guy, Manfred, who wrote software to comunicate with the control modules in the Trans Sport. The 3.8 PCM and the ABS module speaks ALDL 8192 baud, with a certain protocol.

You can easely build yourself an interface to connect a PC to the PCM, and run Manfred´s software (most of it is in english!)

Check this site for interface drawing and software:

Use Manfred´s software running DOS and not the new stuff "TS-Diag" that is not ready yet.
