After programming, reprogramming or replacing the computer:
–switch the ignition off and then on again,
–start and then stop the engine (to initialise the computer) and wait for 30 seconds,
–use the diagnostic tool to carry out the following procedures:
– run command SC001 Enter saved data, to re-establish the injector codes and engine adaptives,
– run command VP010 Enter VIN,
– deal with any faults declared by the diagnostic tool. Clear the computer memory.
– carry out a road test followed by another check with the diagnostic tool.
Note:
If commands SC001 and SC003, have been forgotten or do not work after replacing or (re)programming the
computer, enter the IMA codes for each injector manually by reading the code on each injector (see Replacement
of injectors).
IMPORTANT
– the injection computer retains the immobiliser code for life,
– the system has no security code,
– it is prohibited to perform tests with computers borrowed from the Parts Department or from another vehicle
which must then be returned,
– these computers are hard-coded,
– if the injection computer appears to be faulty, contact the Techline and refer to the fault finding log.

PRE-POSTHEATING UNIT CONTROL
NOTESOnly perform the tests if the statuses do not correspond with the system programming
functions.
YES
NO
When the vehicle is started from cold, the injection computer controls the pre/postheating
unit so that the vehicle can be started.
Status ET007 changes to YES a few seconds after the ignition is switched on and during
pre/postheating.
If the vehicle does not start and status ET007 changes to YES, check:
–the F2 (70A) supply fuse on the preheating unit,
– the resistance of the heater plugs.
Replace any plugs with a resistance greater than 2 Ω.
If the vehicle starts and the status ET007 remains YES during the engine functional
stage, refer to the interpretation of faults:
DF017 Preheating relay control circuit.
DF025 Pre-postheating unit diagnostic connection.
After the engine is started and preheating, the injection computer should stop the pre/
postheating unit operating.
Status ET007 Should change to NO.
In the event that the vehicle does not start and status ET007 remains at NO, check the
continuity and the absence of interference resistance of the following connections:
Injection computer grey 32-track connector C, track A4 Track 9 preheating
unit
Injection computer grey 32-track connector C, track E2 Track 8 preheating
unit
Repair if necessary.
If the fault is still present, refer to the interpretation of faults:

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.

TURBOCHARGING SOLENOID VALVE
NOTESThis command is run if a fault is detected in the turbocharging circuit.
This command checks that the turbocharger and the control circuit are working properly.
Introduction
1 - Check the sealing of the high-pressure air circuit:
Pipe not joined or pierced, pressure sensor disconnected or poorly fitted (seal present), intercooler pierced.
To test the intercooler: stabilise the engine speed between 3,500 and 4,000 rpm with the vehicle stopped and
check that there are no leaks.
Check the resistance of the turbocharging limitation solenoid valve between tracks 1 and 2:
Replace the solenoid valve if the resistance is not: 15.4 Ω ± 0.7 at 20 °C.
Check the injection computer connections.
Check for continuity and the absence of interference resistance on the following connection:
Injection computer grey 32-track connector C, track E1 Track 1 turbocharging solenoid valve
Repair if necessary.
Check for the presence of +12V after relay on track 2 of the turbocharging solenoid valve.
2 - Turbocharger control circuit check
– With the engine stopped, make sure that the control rod is in the rest position.
– Start the engine and make sure that the control rod operates to the high stop.
(when the engine is switched off, the control rod should return to the idle position)
If the control rod does not move correctly, carry out the following checks:
1) Vacuum pressure command check:
– Disconnect the solenoid valve inlet hose and connect it to a pressure gauge.
– Start the engine and run it at a stable idle speed.
– If the vacuum pressure does not reach 800 mbar ± 100: check the vacuum pressure circuit from the vacuum
pump.
– Stop the engine, reconnect the inlet hoses and go to step no. 2.
2) Solenoid valve control check:
– Disconnect the solenoid valve outlet hose.
– Start the engine and run it at a stable idle speed.
– Place your hand on the solenoid valve and block the outlet union with your thumb.
– If you notice no solenoid valve vibration, check the operation of the computer output (step 5).
3) Solenoid valve operation check:
– Connect the pressure gauge to the solenoid valve outlet union.
– Start the engine and run it at a stable idle speed.
If the vacuum pressure does not reach 800 mbar ± 100, replace the solenoid valve.
AFTER REPAIRRestart the conformity check from the beginning.

DAMPER FLAP
NOTESThis command enables the damper flap function to be checked.
– Measure the resistance of the inlet flap valve solenoid valve between tracks 1 and 2.
Replace the solenoid valve if the resistance is not 46 Ω ± 3 at +25 °C.
–Check the continuity and the absence of interference resistance on the following connections:
Injection computer brown 48-track connector B track J4 Track 1 of damper flap solenoid valve
connector
+ 12 V (UPC)Track 2 damper flap solenoid valve
connector
A) Engine running at idle speed:
– Make sure that there is a vacuum pressure of: ~ 900 mb in the solenoid valve inlet hose.
Make the necessary repairs (vacuum pressure circuit conformity and seal).
B) With the vehicle ignition on, engine stopped:
– Check that the inlet flap is open.
If not, clean or replace the air vent unit.
– Disconnect the solenoid valve inlet and outlet hoses.
– Connect a vacuum pump to the inlet union and apply a vacuum pressure of ~ 900 mbar.
If there is a leak, replace the solenoid valve.
– Run command AC014.
– If the solenoid valve opens (vacuum pump pressure gauge returns to atmospheric pressure), go to step C.
– Otherwise, with the solenoid valve connected, check operation of the computer output with a voltmeter:
Voltmeter earth cabletrack 1 of the solenoid valve
Voltmeter positive leadtrack 2 of the solenoid valve
Clear any solenoid valve faults,
Run command AC014.
The voltmeter should display ten ON-OFF cycles (8.75 V then 2.5 V).
If the measurement is correct, replace the solenoid valve.
If the measurement shows is not controlled, contact the Techline.
C) Vehicle with ignition off:
– Connect a vacuum pump to the flap control diaphragm and apply a vacuum pressure of ~ 900 mbar:
– If the diaphragm does not maintain the vacuum pressure, replace the air vent unit (the diaphragm cannot be
disconnected).
– If the diaphragm maintains the vacuum pressure and the valve does not operate, clean or replace the air
vent unit.
– If the diaphragm maintains the vacuum pressure and the flap operates then operate it several times to ensure
that there is no blockage.
Check for clogging of the air vent unit and the valve, and clean if necessary.
AFTER REPAIRRepeat the conformity check from the start.
