code reader
so i my check engine light has been on for awhile now and i just decided to make that code reader to try and figure out why the light is on. i found that thread that shows how to make that contraption but it really doesnt explain how to use it....here comes my question:
anyone out there know how to use it? where do i put the positive banana plug? negative banana plug?
it would be great if anyone know how to use it....let me know if any of you have had any experience.
BTW, i have a '93 300E-2.8ltr that supposedly had some system that makes it easier to read the codes if that helps anyone...

Reading Fault Codes
- Turn ignition key to “on” position, all dash warning lights will be on.
- Remove cover on 16 plug diagnostic connector near battery.
- To read check engine light codes (DM), hold down built in button next to LED light for 3 to 4 seconds, LED light should be on, release button, count the number of LED flashes that follows. Hold button down for 3 to 4 seconds again to check for another code. Keep doing this until all codes have been read and first code comes up again.
- To clear codes - hold down button for 10 to 12 seconds, turn ignition key off for a few seconds, repeat to clear additional codes. Ignition must be turned off between each code cleared.
To check other modules using code tester – insert black plug into socket #1 (ground). Insert red plug into socket #16 (12V power). Insert yellow (third color) plug into socket to be tested, for example #8 or #14. Repeat steps above for LED button using code tester button and LED. Same process for deleting codes as with LED button.
Check appropriate fault code list to determine fault.
Checks codes as quickly as possible at the first sign of a problem. Codes spread from one module to another and will often show up twice or cause other codes. The sooner you check the codes the more likely you are to identify the source problem.

hey battlecat714,
will the codes that you provided be the same for my car since my engine is M104 and the codes are for the M103 (that is what it says when you save the file)...

Here is link to make the thing. Use a old plastic bottle and drill two holes for the led and button in the bottom. Then tuck the wires into the bottle when not in use and screw on the bottle cap to keep all the wires together.

Here is how to determine what the flashes mean. Look up your chassis #.
