These parameters are used so that the history of the last ten activations of the particle filter warning light are
known.
In Vdiag 18, 1C, 54:
Each parameter from PR784 to PR793 records the distance when the particle filter warning light comes on which
is associated with the appearance of DF312.
Each time the particle filter warning light comes on, the vehicle mileage is stored in the following parameter (PR+1).
When all ten parameters have a value other than zero, and the particle filter warning light comes on again, the
distance information for PR784 is cleared and replaced by the new value.
For other Vdiags:
Each parameter from PR784 DF312 record no. 1 to PR793 DF312 record no. 10 contains a record of the vehicle
mileage when the particle filter warning light comes on. The appearance of fault DF312 Speed request is
associated with each of these parameters.
PR784 to PR793 operate through successive copying (when the particle filter warning light comes on, the value of
PR784 is copied to PR785 DF312 record no. 2, the value of PR785 is copied to PR786 DF312 record no. 3 and
so on).
When there are more than ten records, the value of PR793 is deleted. The new mileage is allocated to PR784.
If none of the parameters between PR784 and PR793 is available in the sub-function, this means that no data has
been saved. The parameters appear in the sub-function when they have a value above zero.

In Vdiag 18, 1C, 54:
Each of these parameters contains the vehicle mileage during a failed particle filter regeneration when driving.
Each parameter relates to an engine status. The statuses and parameters are recorded at the same time (for
example PR797 is associated with ET709 Stored engine status no. 4).
Each new recorded value is saved under the next PR (PR+1).
When all ten parameters have a value other than zero and there is a regeneration failure when driving, the distance
information for PR794 is cleared and replaced by the new value.
For other Vdiags:
Every parameter between PR794 Stored regeneration failure no. 1 and PR803 Stored regeneration failure no.
10 contains the vehicle mileage at the time of a particle filter regeneration failure when driving. Each parameter
relates to an engine status. They are recorded simultaneously (for example PR797 is associated with ET709
Stored engine status no. 4).
PR794 to PR803 operate through successive copying (when there is a regeneration failure when driving, the value
of PR794 is copied to PR795 Stored regeneration failure no. 2, the value of PR795 is copied to PR796 Stored
regeneration failure no. 3 and so on).
When there are more than ten records, the value of PR803 is deleted. The new mileage is allocated to PR794.

In Vdiag 18, 1C, 54:
Each parameter between PR816 and PR825 contains the vehicle distance stored when particle filter regeneration
starts when driving. Each parameter is connected with a status "Regeneration request status record". They are
recorded simultaneously (for example PR819 is associated with ET745 Stored regeneration request status
No. 4).
Each new recorded value is saved under the next PR (PR+1).
When all ten parameters have a value other than zero, and a new regeneration starts when driving, the distance
information for PR816 is cleared and replaced by the new value.
For other Vdiags:
Each parameter from PR816 Stored regeneration start No. 1 to PR825 Stored regeneration start No. 10
records the mileage when particle filter regeneration starts for which the status request is recorded in ET742
Stored rege*. request status No.1 to ET751 Stored rege*. request status No.10. (for example PR819 Stored
regeneration start No. 4 is associated with ET745 Stored rege*. request status No.4).
Each time a new regeneration when driving is started, the vehicle mileage is recorded in PR816, as well as its
status in ET742.
PR816 to PR825 operate through successive copying (when regeneration starts, the value of PR816 is copied to
PR817 Stored regeneration start no. 2, the value of PR817 is copied to PR818 Stored regeneration start no. 3

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.

CONTINUED 1
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).
