SYNCHRONISATION
STATUS DEFINITIONNOT DONE: This status indicates that synchronisation has not been carried out.
DONE: This status indicates that synchronisation has been carried out.
NOTESSpecial notes:
Only perform these tests if the status does not correspond with the system
programming functions.
WARNING
Synchronisation is carried out during the engine starting phase. This is established between the camshaft position
sensor and the TDC sensor.
Once this synchronisation has been carried out, it enables the computer to identify cylinder no. 1 and to calculate
the precise position of the cylinder's Top Dead Centre.
Conformity check with the engine stopped and the ignition on, or engine running, and engine coolant
temperature > 80°C
NOT PERFORMED
When the engine is switched off but the ignition switched on, cylinder no.1 is no longer
indicated.
Status ET238 is NOT DONE: synchronisation between the crankshaft and the camshaft
has not been carried out.
COMPLETEDSynchronisation is carried out during the engine starting phase.
Cylinder No. 1 is indicated and synchronisation will be performed once the engine is
started.
If, after several attempts to start the engine, status ET238 remains NOT DONE, refer to
the interpretation of the following faults:
– DF005 Engine speed sensor circuit.
– DF097 Camshaft sensor circuit.
If the engine still does not start, consult ALP2 The engine does not start or starts
with difficulty.
AFTER REPAIRCarry out a road test, then check with the diagnostic tool.

FUEL PRESSURE REGULATOR
STATUS DEFINITIONINACTIVE: This status indicates that the fuel pressure regulator is not active.
ACTIVE: This status indicates that the fuel pressure regulator is active.
NOTESSpecial notes:
Only perform these tests if the status does not correspond with the system
programming functions.
Note:
This solenoid valve regulates the output pressure of the high pressure pump.

STATUS DEFINITIONINACTIVE: This status indicates that the fuel pressure regulator is INACTIVE.
ACTIVE: This status indicates that the fuel pressure regulator is ACTIVE.
NOTESSpecial notes:
Only perform these tests if the status does not correspond with the system
programming functions.
This solenoid valve regulates the flow of fuel entering the high pressure pump and enables an optimum quantity
of fuel to be pressurised according to operating phase; this improves the output of the Common Rail pump and
thereby the output of the engine as well.

FAN UNIT
STATUS DEFINITIONINACTIVE: This status indicates that the cooling fan assembly is INACTIVE.
LOW SPEED: This status indicates that the cooling fan assembly is at LOW SPEED.
HIGH SPEED: This status indicates that the cooling fan assembly is at HIGH SPEED.
NOTESSpecial notes:
Only perform these tests if the status does not correspond with the system
programming functions.
Conformity check with the engine stopped and the ignition on, or engine running, and engine coolant
temperature > 80°C
INACTIVE
The fan assembly is inactive when the coolant temperature does not exceed 96°C.
LOW SPEEDThe injection computer requests the activation of the low speed GMV when:
– the engine coolant temperature is above 96°C,
– the injection computer has system faults that could lead to the engine
overheating,
– the air conditioning is switched on by the driver.
When the high speed fan is supplied:
–status ET022 Low speed fan request becomes activated.
The low-speed fan assembly stops when:
– the engine coolant temperature is below 94°C,
– no fault which could cause engine overheating is present in the injection
system.
– the air conditioning is not switched on by the driver.
