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.

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?
