The Engine Diagnostics option displays faults based on engine
or transmission source. A description of the fault as well as
the suggested action for correction is provided for each fault
occurrence.
Soft Key Commands for Engine Diagnostics include:
GET FAULTS - query the engine(s) ECU for feedback on
diagnostic codes that have been activated and stored in the
ECU for service needs.
UP – DOWN – navigates through the fault list.
SAVE – saves current fault display information.
The following is a list of field definitions contained on the
ENGINE DIAGNOSTICS screen:
• Source – identifies the component having the fault; engine
1, 2, or auxiliary.
• Status – indicates whether the fault has been corrected.
• SPN –"Suspect Parameter Number" - fault code. If
not translated into text by the display, see the engine
manufacturer's literature for the definition of the SPN
number.
• FMI – "Failure Mode Indicator" - fault code. 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.
• Engine Hours – indicates cumulative number of hours of
engine use.
• Description – Most common SPN's and FMI's have text for
the description stored in the display. If there is no text, then
this SPN and FMI must be defined by referring to the engine
manufacturer, or the SAE J1939 standard.
NOTE: This field is only used with certain brands and models
of engines.
• Correction - suggested action for correction.

Fault Code Pop-ups
A fault condition will trigger a pop-up dialog box on the screen
describing the nature of the fault. The following screens are
examples of warning and shutdown fault codes
How to Hide/Show Faults
To hide the fault code pop-up being displayed on the screen,
press the soft key next to the "Hide" icon. The pop-up will
disappear, however the "Warning" or "Stop" icon will remain on
the screen to indicate there is still a fault. Pressing "Hide" does
not clear the fault, it only hides the pop-up message.
When a fault code has been hidden, a "Show" icon will remain
in the bottom right corner. When this soft key is pressed, the
fault code will again be displayed.
Scrolling Through Multiple Messages
The title-bar of the fault code pop-up may indicate multiple
messages, as in 'Diagnostic Message 1 of 3' . Press the HOME
Display to scroll through the different messages.
