Help Deciphering DTCs
 

I've built the handy-dandy LED DTC reader to try and understand my CEL issue, and intermittant simultaneous ASR/ABS lights

After clearing everything and driving for a week or so the CEL returned, as do the ASR/ABS lights (sporadically). This time however, some codes will not clear. I'm thinking I probably have a legitimate fault. Can anyone help with code meanings?

Pin 4) 13 will not clear
Pin 6) 27 will clear
Pin 7) 5, 6 both will clear
Pin 19) 2, 9 neither will clear
Pin 21) 4 will clear
Pin 31) 9 clears but then LED glows steady

Car is 1995 SL500.

If anyone can help me with what the codes mean that would be greatly appreciated.

Or can anyone confirm that the 'answer' is contained within the DTC does list offered for sale here: http://pages.prodigy.net/jforgione/MB_S500.html

Thanks

It's all a mystery without the year/model of your car.

Duh!!
 

Good point. 1995 SL500.

Thanks

Yes, codes would be the same as JimFs S500 coupe, except that pin 21 is roadster softtop and 31 is infrared remote, neither of which would driveability. Next step is to get the fault code lists which should be on Jim's site.
