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.

DEFINITIONThese parameters are shown in miles (km).
NOTESSpecial notes:
These parameters should only be interpreted for ALP 9 Particle filter warning light
comes on too frequently.
Conformity check with engine stopped and ignition on, or engine running, and engine coolant
temperature > 80°C
These parameters are used so that the history of the last ten illuminations of the particle filter warning light are

If DF066 is still present, the command has not been run correctly.
Start the procedure again and follow the instructions.
If this is still not effective, follow the procedure below:
A fault could cause DF066 to be reported, and also incorrect confirmation of command SC002.
If the power latch does not occur after switching off the ignition, the injection computer will not store the new
injector codes:
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 off the ignition and check that the immobiliser warning light flashes 2 seconds after the ignition is switched
off.
If the warning light flashes as soon as the ignition is switched off, the power latch has not been performed and the
command will not be taken into account.
If all these checks do not enable the command to be confirmed, contact the Techline.

NOTESPerform this fault finding procedure:
– following interpretation of an unresolved fault
– following an inconsistency recorded in the parameters,
– following a customer complaint (starting problems, engine speed instability, injection
noise).
STEP 1
Check the continuity and absence of interference resistance on the following connection:
•3RG between the components 120 and 1198.
Check the + 12 V after relay supply to the rail pressure regulator (DRV) of the following connection:
•3FB of component 1198.
If the connection or connections are faulty and there is a repair procedure (see Technical Note 6015A, Electrical
wiring repair, Wiring: Precautions for repair), repair the wiring, otherwise replace it.
Run command AC225, if you can hear a slight whistling noise and rattling from the pressure regulator, go to step
2, otherwise, check the operation of the computer output stage:
Vehicle under + after ignition feed, clear the faults displayed by the diagnostic tool.
With the voltmeter in the direct current position:
With the rail pressure regulator connected, connect the voltmeter earth lead to connection3RG of
component1198 and the positive lead to connection3FB of component1198. Run command AC225, the
voltmeter should display four successive voltages between 2 V and 2.4 V.
If the measurement is not correct, contact the Techline.

conformity (or otherwise) of the parameters and statuses, using the diagnostic tool.
If the customer complaint is not eliminated, perform the following checks.
IMPORTANT:
In the event of the engine overheating above 118°C, the computer deliberately limits the fuel flow (overheating
warning light comes on from 115°C).
– Please observe the cleanliness guidelines and safety advice.
Note:
For the M9R 724 (Vdiag 5C and 58):
The engine is limited to 3000 rpm if the vehicle is stationary or if the vehicle speed is less than 4 mph (7 km/h)
and if the engine is warm.

Perform the following road test (looking for a loss of power when accelerating under full load):
– in the highest gear ratio, accelerate fully,
– lift your foot off the accelerator pedal completely for at least 2 seconds,
– accelerate fully again,
– release the accelerator pedal completely,
– accelerate slightly.
If the loss of power was not noted during slight acceleration and if there was a loss of engine power during each
acceleration at full load, replace the diesel fuel injector return rail and its overpressure valve (see MR364
(Mégane II ph2), MR370 (Scénic II ph2), MR 395 (Laguna II ph2), 402 (Vel Satis ph2), 405 (Espace IV ph2)
Mechanical, 13B, Diesel injection, Diesel injector fuel return rail: Removal - Refitting).

Satis Ph2), 405 (Espace IV ph2), 364 (Mégane II ph2), 370 (Scénic II ph2) Mechanical, 19B, Exhaust, Particle
filter pressure sensor: Removal - Refitting).
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
parameters).
Check the consistency of the signal from the air flowmeter, the engine coolant temperature sensor, the fuel
temperature sensor and the engine speed sensor.
Check the connections, the continuity and the absence of interference resistance of the following components:
– the air flowmeter (apply DF056 Air flow sensor circuit)
– the engine coolant temperature sensor (apply DF001 Coolant temperature sensor circuit)
– the fuel temperature sensor (apply DF098 Fuel temperature sensor circuit)
– the engine speed sensor (apply DF195 Engine speed/camshaft sensor consistency).
