NOTESConditions for applying fault finding procedures to stored faults:
The fault is declared present after the engine is started or following a road test.
Special notes:
If the fault is present:
– particle filter regeneration is inhibited,
– the EGR function is inhibited,
– the vehicle performance is reduced,
–the level 1 warning light is lit and a warning message (or light) is displayed on the
instrument panel.
Priorities when dealing with a number of faults:
Deal with the following faults first:
– DF315 Particle filter differential pressure sensor if it is present.
– DF308 if DF315 is stored.
– DF316 Particle filter diff* pressure sensor if it is present or stored.
– DF226 Damper valve circuit if it is present or stored.
– DF272 EGR valve control circuit if it is present or stored.
– DF647 EGR valve position regulation if it is present or stored.
– DF309 Particle filter downstream temperature sensor if it is present or stored.
– DF899 Regeneration temperature threshold exceeded if it is present or stored.
– DF310 Particle filter upstream temperature sensor if it is present or stored.
– DF778 Turbine upstream temperature regulation if it is present or stored.
– DF652 Turbine upstream temperature sensor circuit if it is present or stored.

NOTESConditions for applying fault finding procedures to stored faults:
The fault is declared present after the engine is started or following a road test.
Special notes:
If the fault is present:
– the special regenerate particle filter warning light is lit or a warning message is
displayed on the instrument panel.
– The vehicle needs to be driven specially to activate particle filter regeneration during
driving.
Priorities when dealing with a number of faults:
Firstly, deal with the following faults:
– DF308 Particle filter clogged if it is present or stored.
– DF311 Failed regenerations limit exceeded if it is present.
– DF315 Particle filter diff* pressure sensor if it is present or stored.
The fault appears after:
– 7 failed regeneration attempts when driving and the weight of soot in the particle filter is greater than
21 g.
– the weight of soot in the particle filter is greater than 58 g.

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.

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

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.

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.
