Viewing Stored Service Codes/Diagnostic Trouble Codes (DTCs)

The diagnostic gauge can request stored service codes (DTCs) from the engine. The stored service codes may be used for diagnostic and service needs. To view the stored service codes, it is necessary to select the DM2 Codes Sub-Menu by pressing the UP or DOWN switch until the top line of the display reads “DM2 Codes”. Then press BOTH the UP and DOWN switches at the same time to select the DM2 Codes Sub-Menu. The gauge will display the stored service codes according to the menus shown in the diagram.
