1. No particle filter regeneration.
2. Write on the repair order the parameter and status relating to the last failure:
Mileage of last DF312
Mileage of last failures
Engine statuses of last failures
E.g.: PR787 = 2794 miles (4657 km); PR801 = 2760 miles (4600 km); engine status = STOPPED
3. Interpretation of the values written on the repair order by the service advisor for the customer:
Before the last time the Particle Filter message or warning light illuminated (appeared at the Mileage of the
last DF312), the customer had not adhered to the driving recommendations: the failure that occurred at the
Mileage of the last failure is due to the engine being switched off.
4. Explain to the customer the procedure to turn off the warning light, making use of the parameters noted in the
repair order: see PA R T D.
PART C
Check that there are no leaks or blockages in the exhaust pipe,
Repair if necessary
Carry out an After-Sales regeneration with the consent of the Techline.
Follow the procedure for command SC017 Particle filter regeneration (see Interpretation of commands).

PART D
Procedure to switch off the Particle filter message or warning light on the instrument panel
The customer must carry out a specific driving operation (cf. vehicle user manual) that consists of:
1. When the engine is warm, drive at a speed greater than 36 mph (60 km/h) for 1 minute to trigger the
regeneration procedure.
2. Keep driving at an average speed of 36 mph (60 Km/h), until the particle filter message or warning light on
the instrument panel goes out. In order for the procedure to succeed, it is necessary to drive without stopping
the engine or leaving the engine running at idle speed for an extended period of time. The regeneration time
depends on the vehicle and driving conditions but should last for 20 minutes maximum.
3. If regeneration when driving fails (the warning light has not switched off or the service warning light has come
on), carry out a particle filter regeneration in the Renault dealership. Run command SC017 Particle filter
regeneration (see interpretation of commands).
Check that there are no leaks or blockages in the exhaust pipe.
Repair if necessary
If the fault is still present, contact the Techline.

1. DEF: Above maximum threshold
NOTESConditions for applying the fault finding procedure to a stored fault:
The fault is declared present after:
– the engine is started.
– a road test.
Special notes:
If the fault is present:
– particle filter regeneration is inhibited.
Use bornier Elé. 1681 for any operations on the injection computer connectors.
Use Wiring Diagram Technical Note, Mégane II ph2, Scénic II ph2.
Note:
This fault is activated in case of considerable oil dilution due to a significant number of particle filter regenerations.
Carry out the following:
– An oil change (see MR 364 (Mégane II) or MR 370 (Scénic II), Mechanical, 10A Engine and peripherals,
Engine oil: Draining – Filling),
– reset the oil wear meter,
– clear the faults.
Reset the oil wear meter after the oil change:
It will be necessary to reinitialise the display of the trip computer.
With the ignition on:
– hold down the TC* button for 5 s.
Re-initialisation has worked when the on-board computer no longer displays the key.
If this is not the case, restart the procedure.
Specific case:
If an oil change is performed before the oil service interval warning is exceeded, reinitialise the display.

PR873OIL OXIDATION SIGNAL
PARAMETER
DEFINITIONThis parameter indicates the distance of the vehicle when the oil dilution threshold is
reached.
NOTESOnly apply the interpretation of this parameter if the OCS (oil control system)
program is activated on the instrument panel. On the instrument panel computer,
check the configuration reading LC106 OCS: WITH
This parameter is not operational in Vdiag44
Conformity check with engine stopped and ignition on, or engine running, and engine coolant
temperature > 80°C, without electrical consumers
The oil condition is calculated by the oxidation program in the injection computer, according to the number of
engine revolutions.
When this count reaches a certain threshold before the end of the oil service period, the injection computer sends
a signal to the instrument panel, which will display service due. Parameter PR873 corresponds to the vehicle
mileage at the time this signal is sent.
Then the instrument panel computer deducts 900 miles (1500 km) before displaying the message Service
required.
IMPORTANT
When the message Service required appears on the instrument panel, the customer must arrange an oil change
within the remaining 900 miles (1500 km).

PARAMETER
DEFINITIONThis parameter indicates the vehicle mileage when the oil dilution threshold is reached.
NOTESThis parameter should be interpreted only if the OCS (Oil Control System) program
is activated on the instrument panel. On the instrument panel computer, check the
configuration reading LC106 O.C.S: WITH.
Conformity check with engine stopped and ignition on, or engine running, and engine coolant temperature
> 80°C, without electrical consumers
The injection computer assesses the dilution rate of the engine oil according to the customer's driving style. When
the dilution level reaches a certain threshold before the end of the oil change interval, the injection computer sends
a signal to the instrument panel, which then displays Service required. Parameter PR875 corresponds to the
vehicle mileage at the time this signal is sent.
IMPORTANT
When the message service required appears on the instrument panel, the customer must carry out an oil service
immediately to prevent damage to their engine.

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.).
