SYNCHRONISATION
NOTESOnly perform the tests if the statuses do 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
ascertain the precise position of the cylinder's top dead centre.
INACTIVE
COMPLETED
When the engine is stopped but the ignition switched on, cylinder no. 1 is no longer
indicated.
Status ET238 is INACTIVE, no synchronisation between the crankshaft and the
camshaft is performed.
Synchronisation is carried out during the engine starting phase.
Cylinder No. 1 is indicated and synchronisation will be performed once the engine is
started.
Status ET238 is "COMPLETED".
If after several attempts to start the engine status ET238 remains INACTIVE, refer to the
interpretation of the following faults:
–DF005 Engine speed sensor circuit
–DF097 Camshaft sensor circuit
If the engine still does not start, (see Customer complaints, ALP2 Starting faults).
AFTER REPAIRCarry out a road test followed by another check with the diagnostic tool.

the switch in the rest position.
Repeat this operation with the switch depressed and check the continuity between
tracks 1 and 2.

ATMOSPHERIC PRESSURE
NOTESThere must be no present or stored faults.
Perform this fault finding procedure after detecting an inconsistency in the Parameters
menu of the computer or following a customer complaint (lack of power, smoke, etc.).
The atmospheric pressure sensor is incorporated in the computer, so no electrical check can be made.
The sensor default value is 750 mbar.
If this value or any other inconsistent value appears, then reset the computer.
If the computer is to be reprogrammed (see Replacement of components).
If the fault persists and remains present, contact the Techline.
AFTER REPAIRRepeat the conformity check from the start.

REFRIGERANT PRESSURE
NOTESThere must be no present or stored faults.
Perform this fault finding procedure after an inconsistency is displayed in the
Parameters menu or after a customer complaint (no air conditioning, etc.).
Step 1
– Start the engine, switch on the air conditioning and increase the engine speed to 1,500 rpm:
– Display PR037 Refrigerant pressure in the Cold loop function on the diagnostic tool:
If the pressure is greater than ~27bar, go to step 2.
If the pressure does not rise, or remains below normal:
– Ensure that the air conditioning compressor and the relay are operating correctly.
– Check the conformity of the refrigerant pressure sensor by comparing* the value displayed by the tool (PR192)
with the reading given by the charging station high pressure gauge.
If the pressure difference = ±1.5bar, (or 1500 mbar):
Check the continuity and the absence of interference resistance on the connections between:
Injection computer, grey 24-track connector C,
track C3Track A of the refrigerant pressure sensor
Injection computer, brown 48-track connector
B, track F1Track C of the refrigerant pressure sensor
Injection computer, brown 48-track connector
B, track F3Track B of the refrigerant pressure sensor
If these connections are not faulty, replace the refrigerant pressure sensor.
If there is no difference, the refrigerant pressure sensor is correct: go to step 2.
Step 2
– Perform fault finding on the air conditioning.
*Note:
The diagnostic tool displays the absolute pressure, the charging station high pressure gauge displays the relative
pressure.
The normal difference between the two is equal to atmospheric pressure, i.e. ~1,000mbar.
AFTER REPAIRRepeat the conformity check from the start.

RAIL PRESSURE
NOTESPerform this fault finding procedure:
– after the interpretation of fault DF053 Rail pressure regulation function,
– after an inconsistency for PR038 noted in the Parameters menu,
– after the interpretation of the fault finding procedure for AC011 Rail pressure
regulator,
– following a customer complaint (starting faults, poor performance, stalling, etc.).
Check the continuity and the absence of interference resistance on the following connections:
Injection computer, brown 48-track connector
B, track G3Track 2 of the rail pressure sensor connector
Injection computer brown 48-track
connector B, track A4Track 3 of the rail pressure sensor connector
Injection computer, brown 48-track connector
B, track C4Track 1 of the rail pressure sensor connector
If all these connections are correct, check for fuel pressure sensor power supply:
+ 5 V Track 3 of the rail pressure sensor connector
Earth Track 1 of the rail pressure sensor connector
Repair if necessary.
Check the sealing of the low and high-pressure diesel circuits (visual inspections, odour) pump housing,
overpressure valve, pipes, rail and injector unions, injector wells, etc.
If all of the previous checks are correct, switch the ignition on, wait for more than 1 minute and display PR038 Rail
pressure.
If the value is less than 50 bar, the rail pressure sensor is correct. If it is greater than this value, replace the rail
pressure sensor and tighten it to 35 ± 5 Nm.
AFTER REPAIRRepeat the conformity check from the start.
