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.

The flow chart on the following page can be used to analyse the driving profile and causes of the activation of this
fault.

PART B
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).
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
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.
