It is amazing that with all the info posted here and on Alldata, I still am not clear on the meaning of the codes.

My '95 E320 wagon has, of course, the 11/4 connector, the version of which, according to Alldata is for a California car, though I know this one was purchased in Atlanta.

Anyway, pin 2 is a pushbutton, Pin 4 is an LED. When I use the pushbutton to read codes, I get codes 2 and 26, which I have not been able to erase (I get the same codes when I use my Impulse Counter gadget...can't erase them with that either).

Could someone tell me what these mean or point me to info on the forum or Alldata?

The only other code I got was a code 8 on pin 6 which, if I'm reading Alldata correctly, is an airbag code. that one I was able to erase. So I'll see if it comes back.

Thanks for the help.

Allan

PS: Is there another plug that I can use the Impulse Counter on for this car...there is mention in various posts of a round plug with 30 odd pins?

'95 E320 Diag Module (pin 3) are:

DTC# PCOF
------ -------
1 No Fault Found
2 Heated oxygen sensor faulty
3 Lambda control faulty
4 Air injection system faulty hot film mass air flow sensor with hot wire

21 Purge switchover valve circuit open or circuit short
22 Crankshaft position sensor signal faulty
23 Intake manifold pressure (in base module pressure sensor-) with engine running too
high/low.
24 Starter ring gear segments and /or crankshaft position sensor faulty
25 Knock sensors or engine control module faulty
26 Upshift delay faulty

DTC 2: The O2 sensors have a rated life of about 60k so it might be time to changed it especially if the heater is gone.

DTC 26: Check for a vacuum leak, broken line, etc.

Jim,

Thanks for the information.

I've been screwing around with the Bowden cable and vacuum modulator so I'm not surprised at code 26.

How do I clear the codes? I did the usual drill...hold down for 8-10 seconds but doesn't clear them.

Again, thanks for your help.

Allan

the faults are ACTIVE so can't be cleared. Had a similar problem with my ASR on my page ('www' icon below) and select Menu #24 for the similar problem.

What if any codes can be read on a 1989 260e. I assume that this is an analogue system. Can anybody verify this. Cannot seem to locate diagnostic socket of any kind. What should I be looking for. Seemed a lot easier on my 1995 S320. Had to sell it too costly to maintain. I now have a Trisco Palm Scanner looking to be plugged into something.

DOES ANYONE KNOW HOW TO READ AND CLEAR DTS CODE FOR A 1994 C280???
THANKS

Thanks Mr. Artur Dalton.

I need de codes chart for my 190E, 2.6, 1988 and 300E, 1988

Please can you send a copy for me.


Thanks

I have figured out from the manual I received with the TRISCO Palm Scanner that I require a 9 pin plug to read codes from a 1989 260e W124. It tells me in the manual that I can read and review the KOER ratio. Can anybody throw any light on the KOER ratio.

Hi

Anyone that knows how all this works on a 1998 CLK 320 cab. It does not have an OBDII connector since it is a european sold car. I have started a thread (Diagnostic tools for the 38 pin diagnostic connector) where I ask if there are anyone that knows how to do diagnostics (and reset) using the 38 pin connector (X11/4) and if anyone knows if there are any PC based scanner/tools that I can use, either direct or with some modification on the hardware.

Thanks for your help

Hi Jim

Thanks. I will look into the Trisco scanner in more detail. It seem to solve the tool-problem for a reasonable amount of money.

But, still, I would very much like to know more details about how the 38-pin connector works for my car (1998 CLK 320). If I know that, I may be able to do my own diagnostic scanner PC-program.

Anybody that can shed any light over this ?

/Michael

Reviving an old thread, go me!

anyway I've got a 95 E320 wagon and a 95 E420. both have the LED as well as the X11 multipin connector. I apparently need to go build the DIY LED tester and then check for codes becuse my E420 is way sick.

I am a little confused as to what is analog and what is digital, are my 95's both?

Your cars are both OBDI flash code reading only, and you have two different connectors - the 320 is 16 pin and the 420 is 38 pin. It's the same code reader but requires different sized pins - the Radio Shack banana plugs for the 320 and about 20 gauge wire for the 420. The 16 pin has a built in LED but the 38 pin does not, although it may have a separate 8 pin connector nearby that does have an LED.

What are the base codes?
