MAIN CONTROL BOARD WARNING AND ATTENTION INDICATOR LIGHTS
The main control board uses a red warning indicator light (62) and a yellow warning indicator light (66) and special dash panel icons to communicate
speci fi c monitored operational (modes) activities to the machine operator. When an operational activity or electrical circuit operational problem is
sensed, the red warning and/or yellow attention lights and appropriate icon are displayed. See short explanation for each icon for the two light
groups below.

Red Warning Indicator Light (62)
62A - Parking brake icon;
Displayed icon shows the operator that the parking brake is set. Operator
needs to release the brake pedal, then the icon and light will disappear.
62B - Diesel oil pressure icon;
Active when low engine oil pressure in the diesel engine is sensed.
Check for possible causes for low oil pressure such as engine crankcase
level is low, improper oil viscosity, fault in oil pressure switch S28, exces-
sive engine wear or defective internal oil pump (relief valve).
Note: This
icon display is for the Kubota diesel engine only. The GM 1.6L has a
low oil pressure monitor that is activated through the 62C engine service
display icon.
62C - Engine service icon;
Sets when the GM 1.6L engines ECM (electronic control module) acti-
vates an engine fault code. See the ENGINE SYSTEM/ENGINE DIAG-
NOSTICS section for more detailed diagnostic help.
62D - Battery low icon;
Indicates low battery voltage. Check alternator output, test the battery,
clean and tighten cables.
62E - Controller critical fault icon;
The main control board has sensed a speci
fi c system component
failure(s) and displays a two-digit number with a wrench icon. See the
controller fault (error) code description table for troubleshooting actions.
Note: Some critical faults will prevent the operation of certain machine
functions.
62F - Hydraulic temperature icon;
Icon sets when the hydraulic oil temperature exceeds an average operat-
ing temp greater than 220 degrees F for longer than 15 seconds. Pos-
sible causes include low oil level in reservoir, debris blocking air
fl ow at the
oil cooler, hydraulic component overloads.
62G Low fuel icon;
Icon sets when the fuel sensors read low fuel levels from the liquid fuel
tank (gasoline /diesel) or low pressure from the LP storage cylinder. Re
fi ll
the gasoline/diesel tank 10 gal capacity. Replace the 33 lbs liquid capac-
ity LP cylinder.
62H Engine coolant temperature icon;
High coolant temperature sensed causes and engine fault. Check for low
coolant level in radiator, debris blocking air
fl ow through the radiator, fan
damage, loose fan belt, leaks, bad engine water pump, engine overload
at high ambient temperature.
