Read Trouble Codes on a 1993 400E

I tried to read the trouble codes on my 93 400e from the 38 pin connector with a blink code reader , but I only get a response ( a single blink , or a counted code ) from pins 31 ,32 , and 33 this is done straight into the 38 pin connector not using a 38 pin break out box , is a breakout box needed ? Am I doing this the wrong way ? The 400e idles low at times .
 
A single blink means there is NO code stored for that particular system.

You can pull codes from specific pins of a 38-pin connector if your leads are small enough -- you don't need a mushroom adapter. However having a mushroom makes it much easier because you can use the larger banana pins and see the numbers for each connector next to the pin on the top of the mushroom.

But yes, as long as you have a map of each of the 38 pins on the connector (less than half of them are active on a 400E or 500E), then you can pull blink codes from them. AS LONG AS your wire leads that go into each of the small receptacles in the 38-pin connector are small enough.....

Note that they will NOT be the detailed codes for some of the systems. To get the detailed codes requires a HHT or emulated HHT in one of the MB STAR DAS laptop systems or clones.

Please read the threads at the top of the listing in this forum:

There is nothing at pins 31-33, you probably have the numbering wrong. The PDF files in the threads linked above will show the pinouts, correct numbers, error codes, and pretty much everything else you need to know.

Have fun!

I get nothing from port number 4 or any other port other than 31,32 and 33 . I have checked it at least 3 times. I don't even get 1 blink from any other ports .
 
You need to put your ground into pin 1, power into pin 2 3 and then use the third lead to test the particular system you want to.

If it's not working, then perhaps your tester is bad, or the lead (wire) end is too large to fit into the connector?

A breakout box would be a good idea, that way you can use larger leads.

I connect the ground to the chassis and the power to battery power and then pin the yellow test wire into a perspective port or pin , and get codes from 31,32 and 33 only .This tester is used on my 300e and it works , thank you .
 
It sounds like you are not using the correct pins/sockets. All the info required is posted above.
