2.6 Engine Shutdown Faults
Description
The engine control module (ECM) continuously monitors vital engine functions for
fault conditions. When a fault condition occurs, the engine will shut down and the
LCD panel will display the fault causing the shutdown.
To reset the ECM and resume operation, return the Engine Start Switch manually
to off “O”. Also refer to section Warning Light.
ECM Display Description
Indicates that the emergency stop
button has been depressed. This
display will remain on until the
emergency stop button is pulled back
out.
Sample display showing Engine
Diagnostic Trouble Codes.
SPN = Suspect Parameter Number
FMI = Failure Mode Identifier.
Indicates that the engine speed
exceeded approximately 2000 rpm
(110% of its rated speed of 1800 rpm)
and the ECM has automatically shut
the engine down.
“Fault Overcrank” is displayed when
the engine fails to start during the
normal cranking cycle, and the Engine
Control Module has automatically shut
down the generator due to an
overcrank condition.
A low fuel fault condition will be
displayed when the fuel tank drops to
5% and the Engine Control Module
has shut the engine down. This fault
condition prevents the fuel lines from
running completely dry and avoids the
need to bleed the lines when the tank
is refilled.
Indicates that the engine speed
dropped below 55 Hz for more than 15
seconds and the ECM has
automatically shut the engine down.
