The display shows the status of the battery. When the
battery voltage is within its “normal” range, 12 –15V, the
ECM displays the voltage value in 1/10V increments on
the run screen.
The display shows the battery low-voltage prealarm set-
ting. When the ECM detects that battery voltage is less
than 12V, the battery voltage reading on the run screen
will blink.
The display shows the battery high-voltage prealarm set-
ting. When the ECM detects that battery voltage is
greater than 15V, the battery voltage reading on the run
screen will blink.
ECM Display Description
John Deere engine diagnostic codes.
SPN = Suspect Parameter Number
FMI = Failure Mode Identifier.
The ten most recent codes will be displayed from most
current to least current. See the John Deere Engine
Manual for details.
The display shows total time, in 1/10 hour increments,
that the engine has been run. New machines, or
machines with new ECMs, will read “No Data” because
the engine has not been run for more than 1/10 of an
hour.
The display shows the amount of time left until service on
the machine is required. To reset the timer to 250 hours,
hold the Hours/Reset toggle switch in the up position until
all the screens have been scrolled through twice.
The display shows the amount the throttle is open at the
current point in time.
