How to Retrieve Active Engine
Fault Codes - Deutz D 2.9 L4 and
Perkins 404F-22 Models
The ECM constantly monitors the engine by the use
of sensors on the engine. The ECM also uses
signals from the sensors to initiate sequential fuel
injection and make constant and instantaneous
changes to ignition timing, fuel delivery and throttle
position to maintain the engine's running condition
at its highest efficiency while at the same time
keeping exhaust emissions to a minimum. When a
sensor fails or returns signals that are outside of set
parameters, the ECM will store a fault code in
memory that relates to the appropriate sensor. The
active fault code will also be displayed on the LCD
screen.
Note: The Perkins 404F-22T is equipped with an
engine fault LED located at the platform control
box.
If an engine fault occurs that does not result in an
engine shutdown, the engine rpm will go into limp
home mode resulting in the loss of high rpm..
Start the engine from the ground control box and
operate various boom functions to verify that an
active engine fault occurs and is shown on the
display.
Note: All faults are stored in the Previous Fault
history menu. These faults will not be erased when
corrective action has been completed.
Note: Software is available from the engine
manufacturer to perform diagnosis through the
engine diagnostic port. Contact the specific engine
manufacturer.
