Table 3-10. Engine Fault Codes
Description
Rail pressure relief valve is open. (PRV)
Rail pressure relief valve can not be opened
due to the railpressure.
Rail pressure is out of the expected average
range.
The PRV can not be opened at this operating
point with a pressure shock.
The pressure relief valve (PRV) has reached
the allowed opening time.
Diagnostic fault check for min error of COM
message.
Rail pressure: the fuel pressure in rail calcu-
lated by ECU is below the target range which
is dependant on the engine speed.
Rail pressure: the fuel pressure in rail calcu-
lated by ECU is below the target range which
is dependant on the engine speed.

SECTION 3 - CHASSIS & TURNTABLE
Possible Cause
Open PRV
Railpressure out of tolerance range (PRV can not
be opened by a pressure peak in this
operating point)
Averaged rail pressure is outside the expected
tolerance range.
Rail pressure has exceeded the trigger thresh-
old of the pressure limiting valve.
The sensed raw value is less than the threshold. Check cabling, check sensor and if necessary
Pressure governor deviation exceeds the limit-
ing value based on the engine speed.
maximum positive deviation of rail pressure
exceeded concerning set flow of fuel.
leakage is detected based on fuel quantity bal-
ance.
Maximum negative rail pressure deviation with
metering unit on lower limit is exceeded.
Action
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 plausibility and if
necessary replace it,
check FCU and if necessary replace it.
Threshold for error detection is an internal ECU
threshold.
Check railpressure, check rail pressure sensor for
plausibility, check FCU.
Threshold for error detection is an internal ECU

Check PRV and replace if necessary.
Replace pressure relief valve (PRV) and reset
fault with Serdia.
replace it,
check connection cable and if necessary repair
or replace it.
