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. One
or more fault LED's will illuminate on the display
located at the ground control box. The active fault
code will also be displayed on the LCD screen.
Note: The Perkins 404F-22 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.
When operating from the platform, if the red
Emergency Stop button is pushed in, the active
fault code(s) will be erased from the display.
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.
With an active fault and the engine running:
(preferred method)
1 At the ground controls, activate the auxiliary
pump toggle switch to shut the engine off.
Note: Do not push in the red Emergency Stop
button or turn the key switch to the off position.
2 Press any soft key below the display.
3 Use the scroll up / down keys to check for
multiple engine fault codes.
With the engine not running:
1 At the ground controls, turn the key switch to
ground controls and pull out the red
Emergency Stop button.
2 Navigate to the Active Fault Menu and use the
scroll up / down keys to check for multiple
engine fault codes.
