• Source – identifies the component having the fault; engine 1, 2, or auxiliary.

• SPM –"Suspect Parameter Number" - fault code
If not translated into text by the HV1000 display, see the engine manufacturer's

The FMI is defined by SAE J1939. If not translated into text, see the SAE standard, or
the engine manufacturer's literature.
• Count – The number of times the event has been flagged.
• Description – Most common SPN's and FMI's have text for the description stored in the

to the engine manufacturer, or the SAE J1939 standard.
• Correction – Trouble-shooting guidelines for corrective action to take in addressing the
fault.
