PR1012WEIGHT OF SOOT AFTER REGENERATION
STATUS
DEFINITIONThis parameter indicates the weight in g of soot present in the particle filter following
regeneration.
NOTESThis parameter should be consulted after running SC017 Particle filter regeneration.
Conformity check: Engine stopped and ignition on, or engine running and engine coolant
temperature > 80°C without electrical consumers
If this parameter is less than 15 g, particle filter regeneration was successful.
If PR1012 is greater than 15 g, it is necessary to perform a second particle filter regeneration using command
SC017 Particle filter regeneration.
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.

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).

–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,
– depending on the operation carried out, select After particle filter regeneration with the diagnostic tool or
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).

MT001TURBOCHARGING FUNCTION
NOTESPerform this fault finding procedure:
– following the interpretation of a fault concerning the air line which cannot be rectified,
– following an inconsistency found in the parameters concerning the air line
(turbocharging pressure or inlet air flow),
– following a customer complaint (starting faults, engine speed instability, lack of
power).
NOTESThis fault finding mode allows you to check dynamically certain mechanical components
on the engine.
To do this, the engine will run a 4-phase cycle which will enable the entire air line to be
checked: air filter, air flowmeter, duct (hoses), air refrigerant, turbocharging pressure
sensor, turbocharger, inlet manifold, exhaust manifold and exhaust pipe.
This test lasts for approximately 50 seconds.
Interpretation of test results:
The data recorded during this test is displayed in the DATA section.
- Identify any data which is outside the tolerance range and apply the different Monitool fault finding procedures
if necessary.
Introduction:
Engine parameters used during this test:
– PR055 Engine speed
– PR035 Atmospheric pressure
– PR059 Inlet air temperature
– PR064 Coolant temperature
–PR132 Air flow
– PR041 Turbocharging pressure
– PR051 EGR valve position feedback

Preliminary test:
Engine speed between: 2480 rpm < X < 2520 rpm
Coolant temperature > 70°C
EGR valve feedback position < 1%
If data from the preliminary checks indicates a non-conformity, check the fuel circuit then contact the Techline.
Interpretation:
If, during phase 1, no data is outside the maximum and minimum limits for each variable, interpret the Monitool
analysis for phase 2.

– The variables measured during phase 1 are correct, i.e. they are within the maximum and minimum authorised
limits. If this is not the case, apply the different Monitool fault finding procedures which relate to the different faults
revealed during the phase 1. To confirm the repairs or modifications carried out, run the MT001 monitool test

Interpretation:
If, during phase 3, there is no data outside of the maximum and minimum limits for each variable, then the air line
is correct and no component replacement is to be carried out. Check the fuel circuit or deal with present or stored
faults which are displayed on the diagnostic tool.
Note: the interpretation of faults during phase 3 should only be carried out in the following situation:
– The variables measured during phase 1 and 2 are correct, i.e. they are within the minimum and maximum
