How to Display Diagnostic Trouble Codes
by Tommy T.

Get in the car, close the door. Perform the following steps fairly quickly (less than 3 seconds) :

Turn key to ON
then back to ACC
then to ON
then back to ACC
then to ON

If there are any stored codes, they will appear immediately, in place of the odometer. For instance an "INTAKE AIR TEMPERATURE SENSOR CIRCUIT HIGH" error will set a code of P0113.

Once the codes have been displayed, you'll see "-----". If there are no trouble codes, the dashes will be the first item displayed.

After a few seconds, the display changes to "-dOnE-".

This is the same procedure used on most, if not all, late model DCX vehicles.

Hi. I tried it on my 2006 300C and it does not work. Is there something I am missing? Thanks, regards, Bob.

Others have had the same problem, it's all in the speed at which you cycle the key in the ignition (even 3 seconds may be too much).

Gotta do it pretty quickly. Hopefully this will help.

Thanks

Thanks Tommy. Guess I'll try faster. Best regards, Bob.

tried it....no work, will go down and try again faster

magnumdude · Sep 14, 2005

did it fast and it worked....thanks....no codes

BobFam · Sep 14, 2005

How?

Hi. Did you go all the way back to ACC each time? I have tried all ways and can't get it to work. I read somewher all you had to do was go to ON then slightly back until the LED's are off and back to On and repeat it stopping at ON. I am going to try again a lot faster both ways. Thanks, best regards, Bob.

I don't have the EVIC as in the example and am happy to report it works for my car as well.

I tried the Fuse 17 option and now I'm getting 0120 and 1120 codes. My question is the letter in front of the code. My car shows a "U" instead of the "P", what is the difference?

Also wanted to know if there is a way to clear the codes, I have read that the OBD II tools won't work (although I probably should try to use mine).

Try pulling fuse 11 for 30 seconds or so.

U = communication
P = powertrain

Anatomy of the DTC

A DTC is made up of 5 digits. The figure below demonstrates the composition of a DTC. With this information it is easier to trouble shoot a DTC without knowing the description of the code.

What do you mean by "then back to ACC"????

hemiboy29 · Jan 7, 2006

Bro i dunno man cuz i got the complete code list and no code starts with any other letter than "P"

The "complete code list" only covers OBDII codes, not manufacturer specific codes. P1000 and higher are manufacturer specific, and so are the ones that start with other letters.

Over in ChargerForum, we've come across this site which has some codes not found in the above OBDII look-ups, which have helped us a time or three:

What if the CEL light blinked 89 times insteaD of the actual code

if MIL flashes after key on it means that not all OBD2 monitors have run since last reset and you'll have to wait till they all run and pass before passing an emission test.
