Complete list of Cummins ISX fault codes?

I have a 2006 Pete 379 with a Cummins ISX 475 and it's showing a big list of codes. I can't find anything on the web that doesn't involve money coming out of my pocket to find out what the codes mean. If you have a complete list of these codes, or know where to get them for free, please send them to me. I have no intention of paying to find out what I have to pay to fix. Anybody who has gone through this should know how I feel. I am a mechanic, and I know how to fix it, but I don't know what to fix. Keep in mind... smarty-pants answers get you reported to yahoo and hopefully banned from answers. No Q&A, just what I'm asking for. Thanks.

    Cummins Engine Codes

  • 1 decade ago

    As noted above, this site has all the fault codes available for all Cummins engines. You will need codes related to the CM870 ECM, which is all ISX engines built after 2002, but before the 2007 DPF systems.

    I had a 1999 Ford F-150 that was putting out about 9 or 10 codes.... I know exactly how you feel about this.. The internet wants you to pay for everything and then they scam you.... I am not sure where you live but try calling a Auto Zone or Kragon's Auto parts and ask them to look the codes up for you.... They do this free of charge... As I called Auto Zone and got my codes given to me for free...
