I have a MB CLK 320 cab - 1998 and it does not have a OBD2 connector.

Does anyone know of a PC based diagnostic tool (or any other tool) that fits the 38 pin connector that does not cost a fortune? Like CarSoft, which is to expensive for me.

Does anyone know the pin configuration on the 38 pin diagnostic connector or where I can find information about it.

Thanks for your help !

Your car definitely has a 'generic' OBD II connector--its under the dashboard on the driver's side. Federal LAW requires them and also specified the code numbers of the components--so every car has the same code # for EGR valve malfunction for instance.

Yep, Feder Law since the 1996 model year. Sometimes they are hard to find and I'm not familiar with the M, but it's there somewhere, guaranteed and I've never seen one that required removing any dash panels for access.

Good luck,

I guess we assume this to be a US version MB. They all DO have OBDII connectors since 1996. Of course an OBDII connection is useless for anything other than OBDII which is rather useless on a MB anyway.

I'm not sure ROW cars have OBDII connectors.

If you really wish to deal with this issue on the 38 pin connector I would suggest spending $18 on a one day subscription at www.startekinfo.com The complete designation of the 38pin connector and the OBDII connector and their relavence to your car will be there along with the complete diagnostic manual for every system you could question at either connector. Many of the documents on the site are pdfs that are downloadable and thus useable forever.

It is a european sold car and that is probably why there is no OBDII connector on the 1998 model.

The www.startekinfo.com site seem to be perfect for this purpose, but since I'm from Europe, I noticed I was not allowed to register (unly for US people). Anyone that have any other ideas. Maybe there is a similar site in europe or maybee anyone already have this information and is kind enough to share it with me or can sell it to me!

I am open for all good ideas !

Sounds like you are on a secret mission and can't tell us where you are. We wish you well. When you can tell us more, we will know if you are on SAE or ISO standards.

Hi again

What more information do you need to help me? I have given the car model and year and it is a european car first sold in germany and now it is in southern Sweden. Do you need more? Please tell me. But I'm very sure there is no OBDII connector, so to be able to do diagnostics, I must use the MB own interface, which as I understand is done from the 38 pin connector.

So my secret mission is not so secret, just that I would like to know how to deal with the connector.

I'm not sure if any of the info that I am about to lead you to will apply, but search against Impulse Counter, titles only.

I started a thread a few weeks ago that asks what can substitute for the impulse counter. In that thread you will find some links that may or may not be of use to you.

Good luck,

Now that I know that the car was built for Germany and is now in Sweden, i might be able to shed some light. Your car was built to ISO standards, International Standards Organization. Cars sold in USA follow SAE, Society Of Automotive Engineers standards. OBDII was first required here in 1996, but some cars had them as early as 1994. The standard was known as J1850. Europe developed its own standard under ISO and called it ISO9141-2. In this system the modules only talked when asked and only to a scanner. they never talked to each other. Then around 1997 ISO14230 was introduced in Europe which was faster and had more interactive communication. Although these systems were developed to create standards, they still fell short and particularly in the area of scanners. A few years ago another system was developed in Europe called CAN or Controlled Area Network. It finally made it to our shores. There is someone who posts here and is a professional mechanic in Ireland, I believe. He is doing research on scanners now and could be a big help. I'll try to find his profile and post it.
