Where do I even start with this, besides saying that I tried multiple scanners, including a Launch x431, Delphi clone, iCarsoft MB v1. Mind you, the iCarsoft at least gave me a P0748 error code. Other than that, I cannot access any modules on the car, neither can I get any vehicle info like VIN no etc. No check engine light, car start first time, albeit some white smoke from the exhaust, but cannot get into the TCM to clear the code, this after I did some repairs to it. I checked fuses everywhere, wiring, got voltage on the diagnostic port as well. I can hear relays click, on all three units that I tried. I would really, really appreciate some advice on where to go next with this issue please.
Gumboil, it may not be good enough to identify the scanner alone. Be prepared to identify the manufacturer and model
of the interface cable and which port you are docking the scanner to.
Hi Raymond. Thanx for the advice. Although Im not quite sure I understand what you said. I only have the 38pin diagnostic port on my car, and all scanners came with there respective connectrs. Even the Launch had a huge black 38pin connectors.
God willing, I got a guy coming around with his Star setup to come and have a look. Ive been Googling and printing out all sorts of possible issues, none of them seem to be the issue. My brain is quite tired of all the reading :-) Feels like Im at Varsity. Fingers crossed, will update yug usy tomorrow afternoon.
okay, I guess that showed my ignorance of your model. most of the w210s in the US have both OBD and MB ports.
but now that you described your system a little more, note that the cable interface to the 38 pin port must be
wired properly for successful docking. check out this thread and see what you think. oh.....wait a sec. I see
that it is your thread on the other MB forum. i think there is another thread showing the wiring schematic for
the plug so let me dig around and see if I can find it
Hi guys. So a friend of mine came around with his Star diagnostic machine, still the same thing. No connection with the vehicle. He was in a bit of a hurry, and as he left he mentioned something about testing resistance across pins of the diagnostic port. It is possible that one of the modules might have a short and pulling down the K-line, making it not work. Does this sound sought of correct?
Yes that is my thread as well, out of desperation I guess
Call your bro back the Xentry has the capability to do all those tests!
Hi Pluto. He was very pressed for time yesterday. We literally had less than 20 mins to scratch in the car. Next week we will have some more time to spare. Could I not measure across ground and the various pins in the meantime?
Its getting difficult to get this chap out to do anymore testing with the MB Star on the car. Is there anything else I could check to try and get a Delphi to at least connect with the car? I found a aftermarrket gps unit installed, this I carefully disconnected, thought it might have made a difference.
I did find this red and white wire, which seems to be an original MB wire, but is connected to and taped up to a plain red wire which runs into a much thicker loom.
That red and white wire is connected to the bottom of this unit via the blue plug
This is for a 2001 US-spec car but it still has the 38-pin connector pinouts. Take a look on page 11 of the file labeled "W210 schematics 1of2" and see if it will help.

Had a look, seems to run from the 16pin OBD2 port to pin 2 on the 38pin connector. I dont have the 16pin obd2 port. I will have a look again this evening and get back to you guys. What is that module called, the one in my photo? If I stand in front of my car, its on the left towards the rear.
Im at a loss for words here. I cannot connect at all. Nothing! Not even a vin no. Delphi allows me to select the w210, correct engine etc, I use the original delphi 38 pin adapter cable and still nothing
