Fault code
J1939 SPN
J1939 FMI
Reason
Effect (only when fault code is active)
338
1267
3
Idle shutdown vehicle accessories relay driver
circuit - Voltage above normal, or shorted to
high source. Open circuit or short to voltage
source detected at the idle shutdown vehicle
accessory/ignition bus relay circuit.
Vehicle accessories or ignition bus loads
controlled by the idle shutdown relay will not
power up.
339
1267
4
Idle shutdown vehicle accessories relay driver
circuit - Voltage below normal, or shorted to low
source. Low voltage detected at the idle
shutdown vehicle accessory or ignition bus
relay circuit when commanded ON.
Vehicle accessories or ignition bus loads
controlled by the idle shutdown relay will not
power up.
343
629
12
Engine control module warning internal
hardware failure - Bad intelligent device or
component. ECM power supply errors have
been detected.
Engine power derate.
346
630
12
Engine control module calibration memory
software - Bad intelligent device or component.
Invalid switch configuration adjustable
parameter setting have been detected by the
engine control module (ECM).
Various optional switch inputs to the ECM may
not operate correctly.
351
627
12
Injector power supply - Bad intelligent device or
component. The ECM measured injector boost
voltage is low.
Engine power derate.
352
3509
4
Sensor supply 1 circuit - Voltage below normal,
or shorted to low source. Low voltage detected
at sensor supply number 1 circuit.
Engine power derate.
383
729
5
Engine intake air heater 1 circuit - Current
below normal or open circuit. A malfunctioning
engine intake air heater circuit has been
detected.
Engine may not start or may be difficult to start.
386
3509
3
Sensor supply 1 circuit - Voltage above normal,
or shor ted to high source. High voltage
detected at sensor supply number 1 circuit.
Engine power derate.
415
100
1
Engine oil rifle pressure - Data valid but below
normal operational range - Most severe level.
Oil pressure signal indicates oil pressure below
the engine protection critical limit.
Progressive power and/or speed derate
increasing in severity from time of alert. If
engine protection shutdown feature is enabled,
engine will shut down 30 seconds after red stop
lamp starts flashing.
418
97
15
Water in fuel indicator - Data valid but above
normal operational range - Least severe level.
water has been detected in the fuel filter.
None on performance.
427
639
9
J1939 data link - Abnormal update rate.
Communication between the engine control
module (ECM) and another device on the SAE
J1939 data link has been lost.
Engine will only idle.
428
97
3
Water in fuel indicator sensor circuit - Voltage
above normal, or shorted to high source.
High voltage detected at the water in fuel circuit.
None on performance. No water in fuel warning
available.
435
100
2
Engine oil rifle pressure - Data erratic,
intermittent, or incorrect. The engine oil
pressure sensor is reading an erratic value.
None on performance.
