SYNCHRONISATION
NOTESSpecial notes:
Only perform these 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 calculate
the precise position of the cylinder's Top Dead Centre.
NOT PERFORMED
When the engine is stopped 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.
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 DONE.
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 does still not start, consult the Customer complaints section, ALP2
Starting faults.
AFTER REPAIRSwitch off the ignition and carry out a road test followed by a test with the diagnostic tool

SC002
ENTER INJECTOR CODES
NOTESThis command should be run after the injectors have been replaced and only if the
vehicle has been configured with IMA.
(ET104 USE OF INJECTOR CODES to YES).
If this command is not performed, the DF276 INJECTOR CODE PROGRAMMING
fault will be present.
WARNING
The letters J and Q, and figures 0 and 9 are not used in IMA coding.
If these characters are used the entry will be invalid.
Cylinder no. 1 is the cylinder located at the engine flywheel end.
Procedure to be followed:
–Read the 6-character alphanumeric codes etched on the upper section of the injector bodies.
–Use command SC002.
–Select the cylinder number for the cylinder concerned in the Desired, column, then confirm.
–Enter the injector code displayed for the cylinder.
–Enter the new codes for each cylinder, then confirm.
–When the command is completed, the modified codes appear in the Current column.
–Check that the codes correspond to those read earlier.
–If the codes entered appear in neither the Current column nor the Desired column, check the codes read and
make sure the data has been entered correctly,
The possible confusions are:
digit "1" with the letter "I"
figure 8 with the letter B
figure 5 with the letter S
–Exit fault finding mode.
–Switch off the ignition and wait for 1 min.
–Switch the ignition back on and check for faults.
–DF276 INJECTOR CODE PROGRAMMING should be stored.
If fault DF276 is still present, the command has not been performed correctly.
Start the procedure again and follow the instructions.
If the codes are still not recognised, check whether the computer's standby has been correctly set:
Switch off the ignition and wait for 1 min.
If the warning light flashes when the ignition is switched off, the computer has not been put on standby and the
command will be ignored.
If all these checks still do not enable the command to be confirmed, contact the Techline.

ALP4 Poor performance
NOTESBefore analysing this customer complaint, check that there are no faults, and the
conformity (or otherwise) of the parameters and statuses, using the diagnostic
tool.
If the customer complaint is not ironed out, perform the following checks:
IMPORTANT
In the event of the engine overheating above 119˚C, the computer will voluntarily limit the fuel flow
(overheating warning light comes on from 115˚C).
–Please observe the cleanliness guidelines and safety advice.
Is the poor performance accompanied by smoke?
YES
Check:
–The conformity of the fuel used: apply test 10 Diesel fuel conformity check.
If the diesel fuel is not correct: – Replace the diesel fuel.
–Change the diesel filter.
–Bleed the low and high pressure diesel circuit.
–The conformity of the assembly of the injectors (presence and conformity of the sealing washer).
Checking procedure:
–Take a straightedge approximately 40 cm long and place it on the 4 injectors. The straightedge should rest on
the 4 injectors.
–If 1 injector protrudes, remove the injector and check that the washer is correct.
–If one injector does not touch the straightedge (clearance of more than 1 mm), remove the injector and check
that the washer is present.
–Clean the injector well and the injector, refit the injector with its correct sealing washer.
The sealing and condition of the inlet circuit: apply test 3 Turbocharged air inlet circuit check.
–The condition of the air flowmeter: apply test 4 Air flowmeter.
–The turbocharger: apply test 9 Air line at the turbocharger, then test 5 Turbocharger control solenoid valve
check and test 6 Turbocharger.
check that the turbocharging pressure follows the increase in engine speed and that the loop difference with the
turbocharging pressure is low.
Otherwise, replace the turbocharger.
NO
AFTER REPAIRcarry out a road test followed by a complete check with the diagnostic tool.

IMPORTANT
Perform these checks without removing the turbocharger and with the vehicle ignition switched off.
Check the turbocharger shaft
WARNING
Respect the following safety precautions:
–wear heat resistant gloves when the engine is hot,
–do not wear loose or baggy clothing and do not wear loose hanging jewellery,
–be aware that the cooling fan assembly may be triggered and pay attention to the operation of the accessories
belt or belts.
Note:
The turbocharger shaft is the shaft connecting the compressor wheel and the turbine wheel.
According to the vehicle type, maximum visual access will either be from above or from below.
Disconnect the air pipe located between the turbocharger and the air filter.
Wearing gloves, check the operation of the turbocharger shaft by turning the vanes manually without forcing.
Is there a point of resistance when the shaft is rotated?
Does the compressor wheel touch the turbocharger housing?
If for these 2 questions the response is NOIf YES for one of these 2 questions
Replace the turbocharger (see MR 364 (Mégane II) or
370 (Scénic II), Mechanical, 12B, Turbocharging,

WARNING
During t hisop eration, it is essential t o:
–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).
IMPORTA NT
–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 litre of fuel at the diesel filter outlet (see MR 364 (Mégane II) or MR 370 (Scénic II), Mechanical,
19C, Tank, Draining the fuel tank), 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 let it settle for approximately 2 minutes.
Is the fuel cloudy or does it
separate into two parts?YESThe diesel fuel contains water and is not compliant.
Drain the fuel circuit, including the tank (see MR 364
(Mégane II) or MR 370 (Scénic II), Mechanical, 19C,
Tank, Draining the fuel tank).
