1237-2 Override switch error
ECU receives a permanent signal; Override switch;
plausibility error
523009-9
PRV error
Rail pressure relief valve: open frequency exceeds
specification; Pressure Relief Valve (PRV) reached
maximum allowed opening count; PRV needs to be
exchanged
523009-10
Rail pressure relief valve open longer than
specification allows; Pressure relief valve (PRV)
reached maximum allowed open time; PRV open
longer than 300 minutes
523350-4
Injector short-circuit
Injector cylinder-bank 1; short-circuit
523352-4 Injector cylinder-bank 2; short-circuit
523354-12 Injector error
Error of its injector high current output; Injector
powerstage output defect
523470-7
PRV error
Rail pressure out of expected average range;
Maximum rail pressure in limp home mode exceeded
(PRV), Monitoring for maximum rail pressure in limp
home mode with PRV
523470-2
Rising pressure forces pressure Relief Valve (PRV)
open; force-open fails
523470-11
Rail pressure relief valve can't be opened due to
railpressure; Pressure Relief Valve (PRV) error; rail
pressure out of tolerance range; averaged rail pressure
is outside the expected tolerance range
523470-12
Rail pressure relief valve open; Pressure Relief Valve
(PRV) forced to open; system reaction initiated, fault
path indicating shutoff condition in case of open PRV;
power reduction may result
523470-14
Rail pressure relief valve open; Pressure Relief Valve
(PRV) is open, Pressure relief valve (PRV) in rail is
open; power reduction may result
523550-12 T50 switch timeout
Terminal 50: ECU receives a permanent signal; T50
start switch active for too long, Startinformation to
Starter (T50-switch) erratic/defect; power reduction
may result
523601-13 (ECU) error
Internal hardware monitoring: deviation of target range
of power supply voltage of sensor output 3; sensor
supply voltage monitor 3 error (ECU), Error in sensor
voltage 3
523612-12
Software error
ECU internal software error; power reduction may
result
Internal ECU monitoring detection reported error
523612-14
Internal hardware monitoring: ECU CPU reset and
cause is logged internally; no item created in error
memory; software reset CPU, software visibility resets
in DSM
