93 Mercedes 300CE code 06
 

We have a 93 Mercedes 300ce with ASR that keeps going into limp mode with a code 06 and the asr light on. The computer connections have all been cleaned. The ETA makes the mechanical sound as the motor turns (actually had tried a new one but no difference). the sensors have all been cleaned, brake light switch replaced. The ASR light does come on if you start car w/foot on brake. the battery voltage is fine. tire pressure is good. Can anyone help? You can turn car off, then back on again and will be fine for a while.

Where did you get the code from???

reading the cars computer with a scanner. it said code 06 ISC EA

OK

Depending on the scanner , that could be ISC from the DM module or a bad Starter LocK sw [ Neutral Saftey SW] from the EA module.

If you go here :

.. then you will see that you can access each module with a LED tool that you can make for a couple of $$.

You want to go to socket # 14 for ASR codes ..
Does your chassis have a CE lamp and a Push Button on the Diagnostic Box next to the battery ??.. If yes , that is Cal version and will have the LED/SW at the box.

I'm not sure about the push button, going to check it out when car is back here and will get back to you. Thank you for your help.

The tool that I have printed will work for a 93 300ce? thanks

OK

If the car has a CE lamp on the dash, then it is Cal Emmssions version [ vs. Federal] , and if YES , then it has the Built-In LED/SW for code retrieval..It will be right under that cap for the Diagnostic Box in front of the Battery.
In NO CE lamp, then there will be NO Led/SW on that box.

But you can make that tool I sent you to the site for..that will allow access to all codes for your car w/o a scanner, as that chassis has Flash Format codes for owner access. [ pre- digital ]..Nice Feature they no longer have after OBD2 came out. Your car is still OBD1.

Yes..it wll work on several models , but I made it to specifically to fit that 16 socket Diagnostic Box with the correct Bananna plugs.
