TROUBLESHOOTING (DIAGNOSTICS)
The engine controller of this generator diagnoses problems
(faults/errors) that arise from the engine control system and
the engine itself.
When any engine faults occur during operation of the
generator the
warning lamp
(diagnostic lamp) located on
the control panel will turn on. If this condition occurs please
perform immediately the engine fault code diagnostic
procedure below.
ENGINE FAULT CODE DIAGNOSTIC PROCEDURE
1. Remove all loads from the generator and place all
circuit breakers in the
OFF
position.
2. Stop the engine.
3. Release the retaining screws that secure the control
panel to the generator frame.
4. Slowly let the control panel fall forward so that the
control box is exposed.
5. To start the diagnostic process, place the
diagnostic
switch
to the
ON
(Figure 73) position.

NOTICE
Make sure to place the diagnostic switch back to
the
OFF
position after completing engine fault code
diagnostic procedures.
6. Verify that the
diagnostic lamp
is
ON
. This indicates
that there is a fault/error in the engine or the engine
control system.
7. Push and hold the
diagnostic button
to identify the
fault and verify the following:
• The diagnostic lamp will start blinking with a pattern
according to the detected fault code 3 times at an
interval rate of 2.4 seconds.
• If two or more fault codes are detected the diagnostic
lamp will repeat the detected fault codes’ blinking
patterns in ascending order. After all the detected fault
codes are shown, the process will repeat starting with
the first fault code.
• If no fault is detected the diagnostic lamp will blink
repeatedly at an interval rate of 2.4 seconds.
NOTICE
For a complete understanding of error codes and
troubleshooting procedures, refer to the enclosed
engine instruction manual.
NOTICE
The diagnostic lamp will indicate the current fault code
with the previous fault code in ascending order.
Also when a fault is detected the fault code will
automatically be saved as the previous code in the
ECM even after the fault has been repaired.
NOTICE
If a fault occurs while the engine is running the
diagnostic lamp will turn on indicating only the current
fault. Please note that the fault code (blinking pattern)
cannot be shown while the engine is running.
