PR1012WEIGHT OF SOOT AFTER REGENERATION
PARAMETER
DEFINITIONThis parameter indicates the weight of soot, in g, in the particle filter after a
regeneration.
NOTESConsult this parameter after using SC017 Particle filter regeneration.
Conformity check: Engine stopped and the ignition on, or the engine running and the engine coolant
temperature > 80°C without electrical consumers.
If PR1012 is less than 15 g, the particle filter regeneration completed correctly.
If PR1012 is greater than 15 g, it is necessary to perform a second particle filter regeneration using command
SC017 Particle filter regeneration (see interpretation of commands).
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 the usual engine oil change before a second After-Sales regeneration (see SC017 Particle filter
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 regulations (see MR364 (Megane II ph2), MR370 (Scenic II
ph2), Mechanical, 19B, Exhaust, Particle filter: Cleaning) and observe the following procedure.
SAFETY INSTRUCTIONS TO BE FOLLOWED:
The regeneration causes exhaust fumes and high temperatures.
The vehicle must be 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.
IMPORTANT
– Check the engine oil level before running the command to avoid any engine racing. The oil level must
be between the minimum threshold 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 briefly pressing the vehicle start button twice (less than 3 seconds).
Switch off the ignition and wait for the diagnostic tool message (maximum time 8 minutes) Communication lost
with computer: EDC16C36, check the tool connection and the computer supply. before switching on the
ignition again.
PROCEDURE TO BE FOLLOWED:
Before a particle filter regeneration, check that there are no leaks or blockages in the exhaust pipe,
Repair if necessary
To run this command, select the command mode on the diagnostic tool, and select command SC017 Particle
filter regeneration.
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.).

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 the usual engine oil change before a second After-Sales regeneration.
Only for Vdiag 50:
– Change the engine oil if a message on the instrument panel requests it.
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 back-pressure. Deal with any faults that appear or replace the particle filter.
Run command SC036 Reinitialise programming and select After particle filter replacement.
– Switch off the ignition and wait for the diagnostic tool message (maximum time 8 minutes): Communication
lost with computer: EDC16C36, check the tool connection and computer power supply.
–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).
– Check the weight of soot: PR383 Weight of soot in the particle filter.
– If PR383
≥ 1 g. Apply the procedure of test 12 Manual clearing of the weight of soot.
Only for Vdiag 50:
– Change the engine oil if a message on the instrument panel requests it.
– 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.
– Explain to the customer the procedure for regeneration when driving to avoid unnecessary repairs: see PART D
in the interpretation of DF312 Speed request.

●Particle filter regeneration failed - run test Temperature upstream of turbine too low: regeneration has
failed because the temperature upstream of the turbine is too low. Run Test 8 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: EDC16C36, check the tool connection and the computer supply.
– switch on the ignition and establish dialogue with the injection computer,
– run command SC036 Reinitialise programming,
– depending on the operation performed, select After particle filter regeneration with diagnostic tool, or After
particle filter replacement
– switch off the ignition and wait for the diagnostic tool message (maximum time 8 minutes): Communication
lost with computer: EDC16C36, check the tool connection and the computer supply.
–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).
– Check the weight of soot: PR383 Weight of soot in the particle filter.
– If PR383
≥ 1 g. Apply test procedure 12 Manual clearing of the weight of soot.
If DF308 Particle filter clogged or DF312 Speed request is still present, contact Techline.
Note:
It is essential to change the engine oil and the oil filter in the following cases:
– following an After-Sales regeneration only if a message on the CLIP diagnostic tool requests it,
– following particle filter replacement,
after a second regeneration (when two successive regenerations).

If the low speed fan assembly relay does not operate when command AC038 is run:
Check the low-speed fan assembly relay mounting and the connections of the engine management computer.
Check the fan assembly connections.
If there is a repair method (see Technical Note 6015A, Repairing electrical wiring, Wiring: Precautions for
repair), repair the wiring, otherwise replace it.
If the fault is still present, check that the relay is actuated by the engine management computer as follows:
Disconnect the low-speed fan assembly relay, and fit a 50 to 100 Ω resistor on the relay mounting in place of the
coil, and connect a voltmeter as follows:
– positive terminal to +12 V battery,

Check the operation of the injectors, run test 10 Poor injector operation.
If the fault is still present
Check the conformity of the accelerator pedal position sensor, the brake pedal sensor, the atmospheric pressure
sensor, the exhaust gas recirculation valve, and the damper valve (see Interpretation of statuses and
Interpretation of parameters).
Check the consistency of the signal for the air flowmeter, the engine coolant temperature sensor, the fuel
temperature sensor and the engine speed.
Check the connectors, the continuity, and the absence of interference resistance of the air flowmeter (apply DF056
Air flow sensor circuit), the engine coolant temperature sensor (apply DF001 Coolant temperature circuit), the
fuel temperature sensor (apply DF098 Fuel temperature sensor circuit), and the engine speed (apply DF195
Camshaft sensor - engine speed consistency).
Check:
– That the diesel filter is not clogged.
– That there are no leaks on the high and low pressure diesel circuits: run test 3 Low pressure circuit check.
– The connection of the oil vapour rebreathing circuit.
– The rail pressure regulator (MPROP) (jammed - stuck), apply the interpretation of command AC011 Rail
pressure regulator.
Check the engine timing (and the position of the high pressure pump sprocket). See the procedure in the
Workshop Repair Manual if necessary.
Test the high pressure fuel circuit:
Run the scenario SC035 High pressure fuel circuit fault finding (see Interpretation of commands).
