Injector power stage output defect.
Defective power stage in ECU.
If error is not removable, change ECU.
Threshold for error detection is an internal ECU
threshold.

Pressure relief valve is forced to open, per-
form pressure increase.
Rail pressure has exceeded the trigger thresh-
old of the pressure limiting valve.
Threshold for error detection is an internal ECU
threshold.
Reset the fault and at reappearance check injec-
tion system.

Pressure Relief Valve (PRV) forced to open.
Performed by pressure increase.
Rail pressure has exceeded the trigger thresh-
old of the pressure limiting valve.
Threshold for error detection is an internal ECU
threshold.
Reset the fault and at reappearance check injec-
tion system.

Pressure Relief Valve (PRV) forced to open.
Shutoff conditions.
Shut Off after PRV Open.
Threshold for error detection is an internal ECU
threshold.
Check PRV opening counter and if necessary
replace PRV, check rail-pressure sensor for plau-
sibility and if necessary replace it,
check FCU and if necessary replace it.

Pressure Relief Valve (PRV) forced to open.
Warning conditions.
Warning PRV open.
Threshold for error detection is an internal ECU
threshold.
Check PRV opening counter and if necessary
replace PRV, check rail-pressure sensor for plau-
sibility and if necessary replace it,
check FCU and if necessary replace it.

Open Pressure Relief Valve (PRV).
Open PRV
Threshold for error detection is an internal ECU
threshold.
Only after ECU reset.
Check PRV opening counter and if necessary
replace it, check rail-pressure sensor for plausi-
bility and if necessary replace it,
check FCU and if necessary replace it.

Pressure Relief Valve (PRV) error; Rail pres-
sure out of tolerance range.
Rail pressure out of tolerance range (PRV can
not be opened by a pressure peak in this
operating point).
Threshold for error detection is an internal ECU
threshold.
Check rail pressure, check rail pressure sensor
for plausibility, check FCU.

1-4-6
Rail pressure out of tolerance range.
The PRV can not be opened at this operating
point with a pressure shock.
Averaged rail pressure is outside the expected
tolerance range.
Threshold for error detection is an internal ECU
threshold.
Check PRV and replace if necessary.

Maximum rail pressure exceeded (PRV).
Rail pressure is out of the expected average
range.
PRV can not be opened.
(A) Check rail pressure relief valve and replace if
necessary.
(B) Check high pressure pumps, pressure relief
valve and metering unit.
(C) Change components if necessary.

Terminal 50 was operated too long.
Start information to Starter (T50-switch)
erratic/defect.
Threshold for error detection is an internal ECU
threshold.
Check cabling, if sensor not working, check start
switch and if necessary replace it,
check connection cable and if necessary repair
or replace it.
