The
control system of Cummins diesel generator can display and record some
operation faults, and these faults are expressed in the form of fault codes.
These fault codes can make faults analysis easier and are recorded in ECM.
These fault codes can be read by using the fault indicator on the dashboard or
the INSITETMTM service tool.
So
how to read land use Cummins genset fault codes? Here Starlight shares some
methods with you:
1.
Fault codes display on fault indicator light
Most,
but not all, electronic fault codes display on the fault indicator light when
they work. When a fault code works, four kinds of fault indicator lights may
turn on.
A.If
“ warning” indicator light is yellow, indicating we should remove faults as
soon as possible;
B.If
“stop” indicator light is red, indicating we need to shut down the diesel
engine safely as soon as possible;
C. Land use diesel generators should be maintained in a state of shutdown until all
faults are removed;
D.When
maintain diesel generator, “Mait” maintenance indicator light will flashes;
E.The
diesel generator set is also equipped with a "water in fuel" (W.I.F)
indicator light. "there is water in fuel" (W.I.F) indicator indicates
that water in oil-water separator of diesel generator needs to be discharged.
As long as the indicator lights up, drainage should be carried out as soon as
possible;
F.To
check whether there are fault codes of diesel generator electronic system and
maintenance indicator codes, the key switch should be transferred to the
"OFF" position and the "diag" diagnostic switch should turn
on;
G.Then
turn the key switch to “ON” connection position, if the current fault code is
not recorded, the indicator lamps will turn on, and the “warning” indicator
lamp and "stop" indicator light will always turn on; if the current
fault codes are recorded, the “warning” indicator lamp and "stop"
indicator lamp will turn on in an instant. The “stop” indicator lamp will turn
on instantaneously and then start recording the fault codes.
2.The
fault code indicator lights flicker in the following order:
A.The
yellow “warning” indicator lamp flashes.
B.1~2s
suspension.
C.The
fault codes will flicker on the red “stop” indicator light.
D.There
will be 1-2s pause between each number.
The
yellow warning light flashes again when the number flickers through the red
indicator. Failure numbers will flicker repeatedly in the same order. Each
fault code will flicker twice and then go to the next fault code.
If
want to skip the next fault code quickly, temporarily pull “idle/diag” adjustment
switch to the (+) position. If want to get back to last fault codes, just
temporarily pull “idle/diag” adjustment switch to the (-) position. If it only
records one current fault code, whatever pull to (+) position or (-) position,
the control system will keep displaying a same fault code.
When
not using diagnostic system, we should shut down the open switch. If the
diagnostic switch is not disconnected or the plug is not pulled out, the ECM
will not record some fault codes.
3.Use
diagnostic tools to read fault codes
We
can read additional fault code information through using INSITETM service tools
(including diagnostic software, data communication adapters and data
communication connectors), can quickly record the number value or state of
control system sensors and switches when the fault codes appear. Because it is
eventually cleared and recently appeared, this data stores the first occurrence
of a failure information. This data is very valuable in attempting to reproduce
or determine the operating conditions of a land use diesel generator in the
event of a failure.
If
we can know to read fault codes on indicator lights of Cummins diesel genset,
when there are some faults, we can know the fault reasons and remove faults
quickly.
