GAUGES AND INDICATORS OF ELECTRONIC CONTROL SYSTEM
Gauges
The following gauges are located on a typical
operator’s console of the electronically controlled
engines. Some operator’s consoles may not have
the gauges described here or may have different
gauges.
NOTICE
The illustrations and descriptions of optional
equipment in this manual, such as the operator’s
console, are for a typical engine installation. Refer
to the documentation supplied by the optional
equipment manufacturer for specific operation and
maintenance instructions.
Indicators
The following indicators are located on a typical
operator’s console.
See the Gauges and Indicators section for
description of indicators that are not described
below.

Figure 11 Typical Operator’s Console
Fault (Figure 11, (1)) (optional) - This indicator will
flash if a fault occurs in the E-ECU or Eco-governor.
The number of flashes and/or the flashing pattern
vary depending on the type or source of the fault.
See Troubleshooting Chart on page 90.
Auxiliary (Figure 11, (2)) - Reserved as an
optional fault indicator.
HEAT (Figure 11, (3)) - This indicator will come on
when the glow plugs are energized when cold
starting the engine. For the electronic controlled
engine, by turning the key switch to the ON position
(Figure 11, (7)), the ECU detects the temperature
of the engine coolant, and the HEAT indicator turns
on for a preset period of time (Maximum 15
seconds), then the glow plug will be preheated. The
time the lamp came off is when to start the
operation.
When an optional after heater is installed, it is
energized for up to 80 sec. after the engine has
started, during which, however, the indicator is not
on.
Others (optional) - Other optional indicators
including those for indicating the air cleaner is
clogged or the water separator is filled with water
can also be installed on the console. See the
operation manual for the driven machine for details.
Machine events including alarms and faults are all
stored in memory of the E-ECU and can be loaded
into the service tool.
