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,
– A specific kind of driving is required to bring about regeneration of the particle filter
when 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.
–DF717 Particle filter upstream pressure if it is present or stored.

Repair request with DF312 Speed request present or stored ONLY
Read the information from theParticle filter history sub-function: PR784 to PR793 Stored DF312 No. 1 to No. 10
Are PR784 to PR793 all equal to 0 miles (0 km)?
Among these parameters (PR784 to PR793):
– Find the parameter with the highest mileage: it is the Mileage of the last DF312.
– Note the parameter index on the order of repair with the relevant mileage value.
E.g.: PR787 = 2794 miles (4657 Km).
Read the information in the Particle filter history sub-function:
PR794 to PR803 Stored regeneration failures No. 1 to No. 10.
Is at least one of parameters PR794 to PR803 = 19660 miles
(32766 km)?
Identify the distance(s) from the values of parameters PR794 to PR803 Stored regeneration failures No.
1 to No. 10 included between the Distance of the last DF312 and the Distance of the last DF312 - 120
miles (- 200 km). This is the Distance of the most recent failures.

PART B
1. No particle filter regeneration.
2.Write on the repair order the parameter and status relating to the last failure:
– Mileage of the last DF312 Speed request.
– Mileage of the last failures.
– Engine statuses of the 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 warning light or message came on (appeared at the Mileage of the last
DF312), the customer had not respected 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 PART D.
PART C
If Vdiag 18:
Reprogram the computer in Vdiag 1C.
Then apply the procedure corresponding to Vdiag 1C.
If Vdiag 1C, 54, 58, 20 and 24:
– Check that there are no leaks or blockages in the exhaust pipe,
Repair if necessary.
– Carry out an After-Sales regeneration with approval from the Techline.
– Follow the procedure for command SC017 Particle filter regeneration (see Interpretation of commands).
– Explain to the customer the procedure for regeneration when driving to avoid unnecessary repairs: see PART D.

PART D
Procedure to switch off the Particle filter message or warning light on the instrument panel
Certain types of driving can trigger illumination of the particle filter warning light or message, and activate fault
DF312. 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 48 mph (80 km/h) for 2 minutes to trigger the
regeneration procedure.
2.Keep driving at an average speed of 48 mph (80 km/h), until the "particle filter" warning light or message 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.
If regeneration fails when driving (the warning light does not go out or the service warning light comes on), check
the exhaust pipe for leaks or blockage. Repair if necessary. Proceed with an After Sales regeneration. Run
command SC017 (see Interpretation of commands).
If the fault is still present, contact the Techline.

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 level 1 warning light is lit,
– the EOBD (European On Board Diagnostic) warning light will come on after three
consecutive driving cycles (starting + 5 seconds + switching off the ignition and
waiting for 1 minute),
– the particle filter fault finding procedure is inhibited,
– particle filter regeneration is inhibited.
Priorities when dealing with a number of faults:
–DF315 if it is present.
–DF308 Particle filter clogged if DF315 is stored and DF308 is present.

NOTESNone.
Check the condition of the differential pressure sensor connector (see Wiring Diagram Technical Note, Laguna
II ph2, Vel Satis ph2, Espace IV ph2, Mégane II ph2, Scénic II ph2, component code 1290).
Check the condition of the engine management computer connector (see Wiring Diagram Technical Note,
Laguna II ph2, Vel Satis ph2, Espace IV ph2, Mégane II ph2, Scénic II ph2, component code 120).
If the connector or connectors are faulty and if there is a repair procedure (see Technical Note 6015A, Repairing
electrical wiring, Wiring: Precautions for repair), repair the connector, otherwise replace the wiring.
