HIGH-SPEED FAN REQUEST
NOTESOnly perform the tests if the statuses do not correspond with the system programming
functions.
Note: Status ET021 High-speed engine fan assembly request and status ET015 High-speed engine fan 2
test change their status at the same time.
ACTIVE
The injection computer requests the activation of the high speed GMV when:
– the engine coolant temperature is above 99°C.
– the injection computer has system faults that could lead to the engine overheating.
When the high speed fan is supplied:
– status ET021 High-speed engine fan request changes to ACTIVE.
– status ET015 changes to RUNNING
In the event that the high-speed engine fan does not work, refer to the UPC fault finding note.
STOPPED
The high-speed fan assembly stops when:
– the engine coolant temperature is below 99°C;
– no fault which could cause engine overheating is present in the injection system.
IMPORTANT!WARNING
If the UPC does not detect the injection computer frames, the low speed engine
fan is supplied until the battery is completely discharged.
In the event that the low-speed engine fan assembly is defective, the high-speed
engine fan assembly will then be activated.
AFTER REPAIRCarry out a road test followed by another check with the diagnostic tool.

INJECTOR CODE USE
NOTESOnly perform the tests if the statuses do not correspond with the system programming
functions.
YES
NO
Status ET104 is YES if the IMA option (individual injector correction) is activated in
the injection computer.
All the injectors have IMA codes etched on the bakelite body, but not all computers
use them.
In the case of a computer configured with the IMA option, the injector codes must be
entered into the injection computer in the following scenarios:
– when one or more injectors is replaced,
– when the injection computer is replaced,
– when the injection computer is reprogrammed.
If the injector codes are not programmed after these operations, fault DF276
Injector code programming will be present, and the engine will operate in defect
mode.
Run command SC002 Enter injector codes applying the procedure described in
the interpretation of this command.
Status ET104 is NO if the computer is not configured to interpret the IMA codes
(individual injector correction).
WARNING
A computer without the IMA option can be replaced by a computer with this option.
In this scenario status ET104 changes to YES after replacing the computer.
Fault DF276 Injector code programming will be present and the engine will operate
in defect mode.
In this case, run command SC002 Enter injector codes, applying the procedure
described in the interpretation of this command.
AFTER REPAIRCarry out a road test followed by another check with the diagnostic tool.

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.

YESFrom the STATUS menu on your fault finding tool, check the conformity of
the immobiliser system: ET003 Engine immobiliser should be INACTIVE.
ET003 correct (Immobiliser code
warning light switched off)
Check the battery charge and the condition and tightness of the terminals.
Ensure that engine speed reaches 250 rpm when the starter motor is
operated. This is displayed on the parameter screen.
Check the engine earths.
Check the conformity of the inertia switch (according to equipment).
Check the presence and conformity of fuel in the tank. Run test 5 Diesel
fuel conformity check.
Check for the 12 V after relay feed on tracks G1 and M2 of connector B
on the engine management computer (via injection relay).
Check the engine fuses (and their mountings, wires and terminals).
test
Operate the starter:
Does the pressure increase in the rail:
Rail pressure = ~ 170 bar at ~ 250 rpm?
NO
Run a fault finding check on the regulator and high pressure pump by
applying the interpretation of command AC011 Rail pressure regulator.
AFTER REPAIRCarry out a road test followed by a complete check with the diagnostic tool.

WARNING
During this operation, it is essential to:
– refrain from smoking or bringing incandescent objects close to the work area,
– protect yourself against fuel splashes due to residual pressure in the pipes,
– wear safety goggles with side guards,
– wear leaktight gloves (Nitrile type).
IMPORTANT
– To avoid any corrosion or damage, protect the areas on which fuel is likely to run.
– To prevent impurities from entering the circuit, place protective plugs on all fuel circuit components
exposed to the open air.
Preparations:
Weigh an empty 1300 ml plastic cup (part no. 77 11 171 413) with its cover (part no. 77 11 171 416) using
electronic scales such as those used in body paint workshops (example: PANDA part no. 77 11 224 995).
Record the weight of the empty plastic cup.
This type of plastic cup is used to prepare paint.
Remove 1 L of fuel at the diesel filter outlet (see MR 364 (Mégane) or 370 (Scénic), Mechanical, 19C, Tank,
Fuel tank: Draining), using a pneumatic transfer pump (part no. 634-200) and place it in the 1300 ml plastic cup.
Cover the plastic cup with its cover and allow it to settle for approximately 2 minutes.
Is the fuel cloudy or does it
separate into two parts?Presence of water in diesel fuel, the fuel is not compliant.
Drain the fuel circuit, including the tank (see MR 364 (Mégane)
or 370 (Scénic), Mechanical, 19C, Tank, Fuel Tank:
Draining).
