Listing Of Diagnostic Trouble Codes (DTC)

The Diagnostic Trouble Codes (DTCs) are output on the diagnostic gauge according to the J1939 standard as a two-part code. The first part is a two to four-digit Suspect Parameter Number (SPN) followed by a one or two-digit Failure Mode Identifier (FMI) code.

Following is a list of SPNs, FMIs, Blink Codes and description of the diagnostic trouble codes that can occur in the various engine systems. Not all of these codes will be present in all engine applications.

When trouble codes appear on the diagnostic gauge, see your engine dealer for repairs as soon as possible.
