Diagnostic Trouble Codes (DTCs) are found on the diagnostic gauge
as 2 part code, according to the J1939 standard. The
fi
rst part is a 2 to 4
digit Suspect Parameter Number (SPN). The second part is a 1 or 2 digit
Failure Mode Identi
fi
er (FMI) code. The diagnostic code will be on the
fi
rst line of the gauge readout and the second line will have "SrvcCode"
on it. The following is a table of the SPNs, FMIs, and description of the
diagnostic fault codes that can occur in various engine systems. Not
all of the codes will be present in all engine applications. When these
trouble codes appear on the gauge see your dealer as soon as possible
for repairs.
