on my 96 SL 500 not all the pins are wired on the diagnostic connector. Only 11 out of 38 have sockets?? Pins wired are 1,2,3,4,6,10,11,13,21,23,30. Since pin 7 has the electronic accelerator this will make troubleshooting th EA very difficult. I have ABS & ASR lights on rough idle with occasional cut out stalling at idle warm only. Sound like a EA since 96 cars have the good wire harness,.But this is an expensive part to throw at a car for troubleshooting purpouses? any sugestions? I do not think the LED code reader works on 38 pin cars. Thanx John.

John,
To start with, the 1996 SL500 doesn't have an EA/CC/ISC computer.
It is integrated into the fuel system computer, ME (motor electronics).

Any ABS/ASR issue would be diagnosed thru the traction system computer.

And you are correct, the old analog LED blink light doesn't work on that model.

Thanx MB DOC ,Thats what I thought, Maybe one of those multiplexers on e bay will work. They run between $100 and $200 and hook to a lap top. they supposedly look at stuff OBDII does not. I have seen used EA,s on ebay for $300 also. I hate throwing parts at stuff! I will make good use of the diagnostic multiplexer though.
