SPN FMI DTC SYMPTOM/CAUSE RECOVERY FROM ERROR
636 8
No inpute of NE sensor
pulse.
Open circuit or short circuit of sensor/
harness. Failure of sensor. No
recognition of NE sensor pulse. Faulty
starting. Engine vibration increases
slightly.
Diagnostic counter = zero
651 3
Open circuit of harness/
coil in 1st cylinder injector.
Open circuit of harness or injector coil.
Engine vibration increases. Injectors
that have no error are operated.
Key switch turn OFF.
652 3
Open circuit of harness/
coil in 2nd cylinder
injector. Open circuit of harness or injector coil.
Engine vibration increases. Injectors
that have no error are operated.
Key switch turn OFF.
653 3
Open circuit of harness/
coil in 3rd cylinder
injector. Open circuit of harness or injector coil.
Engine vibration increases. Injectors
that have no error are operated.
Key switch turn OFF.
654 3
Open circuit of harness/
coil in 4th cylinder
injector. Open circuit of harness or injector coil.
Engine vibration increases. Injectors
that have no error are operated.
Key switch turn OFF.
676 0
Glow heater relay driving
circuit overheat.
Glow relay coil resistance or load is
too high. Faulty starting. White smoke
increases.
Key switch turn OFF.
676 5
Open circuit of glow relay
driving circuit.
Open circuit of harness or relay
coil. Faulty starting. White smoke
increases.
Key switch turn OFF.
679 7 Pressure limiter not open.
Rail pressure value is sticking or not
enough engine power to open PLV
forcibly.
Key switch turn OFF.
723 2
G sensor pulse number
error. After fault opening PLV, rail pressure is
above 160 MPa.
Diagnostic counter = zero
Engine stops.
723 8
No input of G sensor
pulse.
Open circuit or short circuit of sensor/
harness. Failure of sensor. No
recognition of G sensor pulse. Engine
hesitates at start-up.
Diagnostic counter = zero
1077 2 Failure of CPU. CPU fatal error. Engine stops. Key switch turn OFF.
1239 1
Fuel leak in high-
pressured fuel system.
Fuel consumption is calculated
from the difference of fuel pressure
of, before and after the injection.
Error is detected when excess fuel
consumption is found. Engine could
stop.
Key switch turn OFF.
1347 3 +B short circuit of SCV. EGR stops. Key switch turn OFF.
1347 4 SVC drive system error.
Open circuit or ground short circuit of
SCV.
Key switch turn OFF.
EGR stops, engine forcibly stops later.
1347 5
Open circuit of SCV
(MPROP)
Open circuit short of SVC.
Key switch turn OFF.
EGR stops, engine forcibly stops later.
1347 7
SCV stuck in open
position.
Actual rail pressure continuously
exceeds the command rail pressure.
Discharge request of supply pump
goes below 0 mm
3
/st and the actual
rail pressure is 10 MPa for 26 seconds
or more. engine may stop.
Key switch turn OFF.
