TROUBLESHOOTING
Fault code
(Lamp)
Reason Effect
559
(Orange)
Injector metering rail 1 pressure
Data valid but below normal operation range.
Moderately severe level. The ECM has
detected that fuel pressure is lower than
commanded pressure.
•
•
Possibly hard to start, low power or engine
smoke.
689
(Orange)
Engine crankshaft speed/position
Data erratic, intermittent, or incorrect. Loss of
signal from crankshaft sensor.
•
Engine can run rough. Possibly poor starting
capability. Engine runs using backup speed
sensor. Engine power is reduced.
731
(Orange)
Engine speed/position camshaft and crankshaft
misalignment
Mechanical system not responding properly or
out of adjustment. Mechanical misalignment
between the crankshaft and camshaft engine
speed sensors.
•
Engine will run derated. Excessive black
smoke, hard start, and rough idle possible.
951
(None)
Cylinder power imbalance between cylinders.
A power imbalance between cylinders was
detected by the ECM.
Possible low power, rough idle, or misfire.
1117
(None)
Power supply lost with ignition on
Data erratic, intermittent, or incorrect. Supply
voltage to the ECM fell below 6.2 VDC
momentarily, or the ECM was not allowed to
power down correctly (retain battery voltage
for 30 seconds after starter switch OFF).
•
Possible no noticeable performance effects or
engine dying or hard starting. Fault information,
trip information, and maintenance monitor data
may be inaccurate.
1376
(Maintenance)
Engine camshaft speed/position sensor
Data erratic, intermittent, or incorrect. The
ECM has detected an error in the engine
camshaft speed/position signal.
•
Possible poor starting. Engine power derate.
1383
(Orange)
Intake manifold 1 pressure sensor circuit
Voltage above normal or shorted to high
source. High signal voltage detected at the
intake manifold 1 pressure circuit.
•
Engine power derate to no air setting.
1384
(Orange)
Intake manifold 1 pressure sensor circuit
Voltage below normal or shorted to low
source. Low signal voltage detected at the
intake manifold 1 pressure circuit.
•
Engine power derate to no air setting.
1411
(Orange)
Generator output frequency adjust
potentiometer circuit
Voltage above normal or shorted to high
source.
•
No action taken by the ECM.
1412
(Orange)
Droop adjust potentiometer circuit
Voltage above normal or shorted to high
source.
•
No action taken by the ECM.
1418
(Orange)
Gain adjust potentiometer circuit
Voltage above normal or shorted to high
source.
•
No action taken by the ECM.
1597
(Maintenance)
Electronic control module critical internal failure
Bad intelligent device or component. •
No action taken by the ECM.
1695
(Orange)
Sensor supply 5
Voltage high error. •
No action taken by the ECM.
1696
(Orange)
Sensor Supply 5
Voltage low error. •
No action taken by the ECM.
