I am not sure but does Cummins insite do other things besides codes ? I thought I saw diagnostics and can't find it . If it does how do I use the program
ecm diagnostics tests in left menu lets you perform various tests on engine used for diagnostics if you lost your subscription and it goes to basic I think you lose the ability to clear codes and to perform ecm tests
OEM trained in wiring and all engine platforms for over 20 years
Once you pull fault codes, right click on the code and go down to "FAULT CODE TROUBLE TREE" and there you will find your diagnostics. Don't overlook the blue hyperlinks. They take you to good places!!
