Action Taken When the Fault Code is Active: The ECM illuminates the amber CHECK ENGINE lamp immediately when the diagnostic runs and fails. After all that, Cummins only uses one code number which relates to the SPN and FMI portion of this code system. Diagnostic Fault Codes For Cummins Engines Applies to Engine Models QSB T2, QSC T2, QSL T2, QSM11, QSX15, QSK19, QSK23, QST30, QSK45/60/78 Note: These fault codes are current at date of publication. They are employed to help everyone working on engines find the problem without too much guess work. Some fault codes are warnings, others cause the generator to shutdown or prevent it from starting.
