Cummins Diesel fault codes

You might want to copy this for future reference:

(Personally, on my '07, 6.7 2500 have done the DPF delete and Smarty Jr chip)

Procedure for retrieving fault codes on Dodge 6.7 Cummins trucks:

1.Select “total miles” on the trucks odometer, not trip.
2.Insert ignition key.
3.Move the key from LOCK TO OFF, THEN PAUSE.
4.Move ignition key to ON/RUN.
5.Move ignition key BACK TO OFF.
6.Move ignition key to ON/RUN.
7.Move ignition key BACK TO OFF.
8.Move ignition key to ON/RUN and STOP THERE!
The Key cycles from OFF to ON/RUN should be done in less than 5 seconds.

You then can read the codes on the truck’s odometer. (See complete list below.)

Once you have pulled the codes, contact your Good Sam ERS, and ask to speak to a technician. The tech will be able to advise you on the possibilities and offer further guidance. Once you know the problem, you will have a better idea if you want to work on the repairs yourself or take it to a qualified professional.
