OBD1: All the same?
 

1995 - 993c2

Wondering if I can just buy any old OBD1 unit or if each car manufacturer has their own version?

What OBD1 unit to buy?

Cryptic request,......:) :)

Are you looking for an OBDI scan tool? A DME?

More info needed to be able to assist,....:) :)

Günter, which OBD1 connector do you have; the "earlier" round 19 pin or the following connector...

If the above, T-OBD Reader

Thanks Alex, I appreciate it!
T-OBD is in stock as well as the 19-pin adapter.

Cheers,
Tore

I noticed the availability of the 19 pin adapter after posting.

And your OBD reader is a whole lot cheaper and less work than the OBD reader that I made from a kit.

Yes, Alex, mine looks like your picture: 16 holes etc., thanks. :)

Hello Steve:
We're planning a tour to Portland next weekend, May 21-23, posted on Pac.North West, Pelican.
Staying at Park Lane Suites.

I would just like to get a basic understanding of how to read a "Scanner"? if that's what it is called.

You know, plug it in and learn more about OBD1 and how it works.

Gunter,

on the OBD1 cars you can read the code without a tool, just by pressing the gas pedal before turning the ignition key, then the codes will flash on the dashboard.
It's a good idea to keep a list of the error codes in the glove box.
Do a search for this "feature" and the right procedure.

A tool is great if you need to clear the codes.

OBD-I cars used proprietary tools and software with each manufacturer deploying their own protocols. I've not used the Durametric tool so I cannot comment about its capabilities and limitations.

We use both the Bosch Hammer (Porsche's version of the KTS-300 and their own software) as well as the PST-2 to communicate with these cars and "talk" to all the modules.

While not cheap, you may be able to find a used Hammer with the proper cables and last version of Porsche software as I think thats a good tool for these cars.

I use the Scantool windows software made by Rennlisters in my car, works perfectly and connects to all electronic units, ABS, alarm, air bag, CCU and DME.
I have made a copy of the software on my website.
Cheers,
Tore

Many thanks,

Sounds like I need to get a book on the issue like "OBD1 for Dummies" or similar, as well as doing more searches.
So, the codes can be displayed but one needs a special tool to clear them.

I'll make a copy of the fault codes for the glove box. :)

Being at least 4 hours (more like 7) away from a possible facility makes it challenging.

Actually, it looks like you may even be able to clear them the same way. But I've never tried.
