SC002ENTER INJECTOR CODES
NOTESThis command is carried out after the replacement of one or more injectors.
Engine stopped.
To enter this information, select command SC002 in the diagnostic tool.
Procedure to be followed:
– Read the 7-character alphanumeric codes engraved on the upper section of the injector bodies. The IMA*
codes should be read from left to right (see illustration in MR 402 (Vel Satis ph2), MR 395 (Laguna II ph2),
MR 364 (Mégane II ph2), MR 370 (Scénic II ph2), MR 405 (Espace IV ph2) Mechanical, 13B, Diesel
injection, Diesel injector, Removal – Refitting)
Note: When entering characters, confusion can arise between:
– Figure 1 with the letters I and L,
– Figure 2 with the letter Z,
– Figure 5 with the letter S,
– Figure 6 with the letter G,
– Figure 8 with the letter B.
After programming or reprogramming the computer, it is essential to enter the 4 injector codes before confirming
the entry.
– Enter each injector code for the associated cylinder.
–Important: cylinder no. 1 is located at the timing end.
– Confirm the change of injector code configuration.
– 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.
– Exit fault finding mode.
– Switch off the ignition and wait for the diagnostic tool message (maximum wait 8 min): Loss of dialogue with
the computer: EDC16 CP33, check the tool connection and the computer supply.
– Switch the ignition back on and check for faults.
–DF066 Injector code(s) should be stored.

SC017PARTICLE FILTER REGENERATION
NOTESOnly run this command after interpretation of the following faults:
– DF308 Clogged particle filter,
– DF311 Failed regenerations limit exceeded,
– df312: speed request.
WARNING:
– It is essential to observe the health and safety guidelines (see MR364 (Mégane II ph2), MR370 (Scénic II ph2),
MR 395 (Laguna II ph2), 402 (Vel Satis ph2), 405 (Espace IV ph2) Mechanical, 19B, Exhaust, Particle
filter: Cleaning) and follow the procedure below.
SAFETY INSTRUCTIONS TO BE FOLLOWED:
The regeneration causes exhaust fumes and high temperatures.
It is strongly recommended that you put the vehicle outside during regeneration.
If it is not possible to carry out regeneration outside, use an extractor fan that can withstand the very high
regeneration temperatures (400°C at the exhaust outlet).
Perform regeneration on a surface free from fire risks (oil, dry leaves, etc.).
Nothing should be left in the vicinity of the exhaust pipe.
Check that there are no leaks or blockages in the exhaust pipe,
Repair if necessary.
WARNING:
Check the engine oil level before running the command to avoid any engine racing. The oil level must be
between the minimum level and the middle level on the oil dipstick.
Before performing a particle filter regeneration, it is essential to deactivate the air conditioning
compressor (risk of engine damage) and all the electrical consumers.
IF NECESSARY:
Regeneration can be stopped by pressing the engine start button twice briefly (less than 3 seconds).
Switch off the ignition and wait for the diagnostic tool message (maximum time 8 minutes) Communication
lost with computer: EDC16 C33, check the tool connection and the computer power supply before
switching the ignition back on.

PROCEDURE TO BE FOLLOWED:
To run this command, select the command mode on the diagnostic tool and run command SC017.
When regeneration is complete, a message will indicate whether regeneration was successful, and what
operations need to be carried out (filter replacement, whether an oil service is required, etc.).
DESCRIPTION OF THE PROCESS
particle filter regeneration takes place in 3 stages (values given as a guide only):
Heating phase: the speed is fixed or fluctuating around 3000 rpm.
– This phase lasts at least 6minutes, until the coolant temperature is above 80°C.
–Regeneration phase: the speed is fixed or varies around 2000 rpm. Engine injection is retarded. The exhaust
fumes rise in temperature and burn the soot retained in the particle filter. The particle filter downstream
temperature starts to rise after the particle filter upstream temperature due to the volume of the particle filter.
Then the combustion of the soot stored in the particle filter causes the particle filter downstream temperature
to increase, possibly reaching more than 700°C depending on the amount of soot in the filter (with a particle
filter upstream temperature of around 600°C). This phase lasts about 30 minutes.
–Cooling phase: the engine speed is fixed or varies around 2000 rpm.
– Engine injection returns to normal and the exhaust gases cool the particle filter.
– This phase lasts 3 minutes. At the end of this period, the engine speed returns to idle speed or remains fixed
at 2000 rpm.
The process lasts at least 40 minutes (the regeneration time will be increased depending on how long it takes
for the coolant to heat up to 80°C).

VALIDATING THE REGENERATION PROCESS:
At the end of regeneration, a message appears to announce whether the regeneration was successful:
•Particle filter regeneration finished:
Consult PR1012 Weight of soot after regeneration. If this parameter is less than 15 g, the particle filter
regeneration was successful. If PR1012 is greater than 15 g, it is necessary to carry out a second particle filter
regeneration using the diagnostic tool and run command SC017.
IMPORTANT:
Before performing a second After-Sales regeneration of the particle filter, the engine must be allowed to cool
down for 2 hours with the bonnet open.
Do not carry out an engine oil change before a second After-Sales regeneration.
For Vdiag 28 and 62:
Change the engine oil if requested by a message on the instrument panel.
For the other VDiag:
Consult PR848 Number of regeneration failures. If PR848 is greater than 3, change the engine oil.
Particle filter too full - replace the particle filter: regeneration has failed. The weight of soot in the particle filter
is so great that it is creating a counter pressure. Deal with any faults that appear or replace the particle filter. Run
command SC036: Reinitialise programming and select After particle filter replacement.
For Vdiag 28 and 62:
Change the engine oil if requested by a message on the instrument panel.
For the other Vdiags:
Consult PR848 Number of regeneration failures. If this parameter is greater than 3, it is essential to
change the engine oil.

–Particle filter regeneration failed: regeneration failed because the temperature upstream of the turbine is too
low. Apply Test 11 Temperature upstream of turbine too low.
In all cases, carry out the following operations:
– switch off the ignition and wait for the diagnostic tool message (maximum time 8 minutes) Communication
lost with computer: EDC16 CP33, check the tool connection and the computer supply,
– switch on the ignition and establish dialogue with the injection computer,
– run command SC036,

After particle filter replacement,
–switch off the ignition and wait for the diagnostic tool message (maximum wait 8 min): Loss of dialogue
with the computer: EDC16 CP33, check the tool connection and the computer supply voltage,
– then switch on the ignition again,
clear the present or stored faults from the computer memory (operation to be carried out within 3 minutes of
switching on the ignition).
Note:
Always change the engine oil and the oil filter in the following cases:
• following an After-Sales regeneration only if requested by a message on the CLIP diagnostic tool,
• after particle filter replacement following DF311 Number of failed regenerations exceeded,
– after a second regeneration (when two successive regenerations).

SC031OPERATIONAL FAULT FINDING OF CYLINDERS
NOTESThis command allows fault finding to be carried out on the output of each cylinder and
each injector and applies to all the Vdiags except Vdiag 18, 04 and 44.
Note:
For Vdiags 18, 04 and 44, check that the fuel flow correction value of parameters
PR364 Cylinder no. 1 fuel flow correction, PR365 Cylinder no. 4 fuel flow
correction, PR405 Cylinder no. 2 fuel flow correction and PR406 Cylinder no. 3
fuel flow correction is between: -5 mg/st < X < 5 mg/st.
Reminder: cylinder no. 1 is located at the timing end.
Procedure to be followed:
– select scenario SC031,
– once the conditions have been met, press the confirm button; the test will take approximately 5 minutes,
– the tool displays cylinder no. 1 cut-off and there will be a perceptible engine speed variation when the cylinder
is cut off; then the same procedure for the other three cylinders,
–the diagnostic tool displays the results,
– end of test.
Interpretation of correct results:
– If the displayed results are “VALID”, it means that the entire cylinder and injector assembly is in order. There
is no need for any operation.
