ELECTRONIC CONTROL SYSTEM
The engine control system is an electronically operated fuel
control system that also provides many operator and vehicle
features as well as reducing exhaust emissions while
optimizing engine performance.
The ECM performs diagnostic tests on most of its circuits
and will activate a fault code if a problem is detected in one of
these circuits. Along with the fault code identifying the
problem, a snapshot of engine operating parameters at the
time of fault activation is also stored in memory. Some fault
codes will cause a diagnostic lamp to activate to signal the
driver. The fault codes can be read using the LCD display in
the steering column or with the correct service tools. The
ECM communicates with service tools through a SAE J1939
datalink.
Engine Control System Switches and
Indicator Lamps
Refer to the Operator’s Manual for complete information on
the following switches and indicator lamps.
Engine Diagnostic Test Mode Switch
The Diagnostic Test Mode Switch is used when servicing the
engine’s electronic control system. It is a two position on/off
rocker switch used to activate the testing mode (fault
codes). When the test mode switch is on, and used in
conjunction with the Diagnostic/Idle Switch, access will be
gained to toggle up and down through the fault codes
displayed on the steering column LCD display.
Diagnostic/Idle Switch
The Diagnostic/Idle Switch is a two position (+/-) momentary
rocker switch that provides idle-control inputs that increases
the engine idle (when the test mode switch is in the OFF
position) or diagnostic mode fault codes—when the test
mode switch is in the ON position.
Manual DPF Regen Switch
The Engine DPF (Diesel Particulate Filter) Switch is located
on the right side of the overhead control panel. This switch is
a three position switch; Disable Regen/Off/Start Regen.
Press this switch to Start Manual Engine Regeneration or to
Disable Regeneration.
Emergency Stop Switch
The crane Emergency Stop Switch is located on the right
hand console and is used to shut down the engine. Push the
red button in to shut down the engine, rotate the knob and
pull out to resume normally operation.
Engine Warning Indicator
The Engine Warning indicator is located in the steering
column gauge display. It illuminates amber when energized
by a signal from the engine ECM.
If this indicator light illuminates, see Engine Operator’s
Manual.
Disable Regeneration Indicator
The Disable Regeneration indicator is located in the steering
column gauge display. When the manual regen switch is in
the regeneration disabled position this indicator is
illuminated.
High Exhaust System Temperature Indicator
The High Exhaust System Temperature indicator is located
in the steering column gauge display.
During regeneration it is possible for the engine exhaust to
reach temperatures exceeding 1200° F (649° C). The DPF
indicator will illuminate to warn the operator of these high
temperatures.
Engine Wait To Start Indicator
The Engine Wait To Start indicator is located in the steering
column gauge display. It illuminates amber for a period of
time when the ignition switch is in the ON position. The
engine should not be cranked until the Wait-To-Start light
turns off. This light is controlled by the engine ECM.
Emergency Engine Stop Indicator
The Emergency Engine Stop indicator is located in the
steering column gauge display. It illuminates red when
energized by a signal from the Emergency Stop Switch. In
addition, a warning buzzer will also sound.
The engine will not start when this indicator is illuminated.
FUEL SYSTEM
Description
The fuel system consists of the Fuel Tank, Primary Fuel Filter
with Water Separator and Water in Fuel Sensor, Secondary
Fuel Filter, Lift Pump, Injection Fuel Pump, Fuel Injectors,
and Return Fuel Cooler. All components except the Fuel
Tank and are installed on the engine or supplied with the
engine for remote mounting.
Fuel Tank
The Fuel Tank (Figure 7-2) is a steel cylinder-type tank
located on the left side of the machine. The Fuel Tank has a
draw capacity of 100 gal (379 l). A connection on the bottom
of the tank provides for fuel supply to the engine. Surplus fuel
from the engine is provided to the bottom of the Fuel Tank
below the fuel level. The tank is equipped with a non-vented
