Codes
To interpret an SPN and/or FMI number, refer to the documentation of the engine
manufacturer.
SPN means "Suspect Parameter Number", for example, if the coolant water temperature
becomes too high, the SPN code "110" will be shown.
FMI means "Failure Mode Indicator", for example, if the temperature in the above example is
at shutdown level, the FMI code "0" will be shown.
Oc means "occurrence counter" and it indicates how many times a specific alarm has
occurred., for example, if the specific alarm in the above example (SPN 100, FMI 0) has
occurred 2 times, the oc code "2" will be shown.
NOTE: In the table below a specific SPN number is linked to the same
FMI and oc number.
