Mercedes 560SEC ASR Light Problem

[zcc]

Dear all,

This is my first post in your forum. I so wanted to find a good Mercedes forum and finally I found it. I read posts and replys then decided that I have to join with you. I have 4 Mercedes cars. 3 are 560 and one 300 and all are W126 body.

I'm a computer engineer but I really love Mercedes mechanical work. My recent problem now is with the ASR system in my 560SEC 1989. No one could fix it. Simply I'll describe you the problem. When I start the engine the ASR light goes on and no ASR system works. I checked almost everything but useless. Can anyone help me please with this problem? I search the Internet for solutions but useless. Thanks : ))..

IN the USA only 1991 & later cars had ASR!!!
On that & any other 1991-93 car with ASR & CIS-E injection there isn't any rear diagnosis other than pin to pin testing!

Very HARD to diagnose! we hated to see those cars at the dealer! Even after pin to pin testing w/socket box the results always required a substitute part to be installed.

I do have wiring info & pin to pin testing info. Good luck

Thank u ver much M.B.DOC for replying. Where is that substitute part that I can replace? And how can I get your wiring info & pin to pin testing info?

Thanks a lot : ))..
