Procedure to switch off the Particle filter message or warning light on the instrument panel.
Certain types of driving can trigger the illumination of the particle filter warning light or message, and therefore
cause fault DF312 to appear. The customer must drive in a specific way (refer to vehicle's user manual) which
entails:
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. Continue to drive at an average speed of 48 mph (80 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.
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. First, check the exhaust pipe for leaks or
blockage. Repair if necessary.
Run command SC017 Particle filter regeneration (see Interpretation of commands).
If the fault is still present, contact the Techline.
AFTER REPAIRDeal with any faults.
Carry out a road test followed by another check with the diagnostic tool.

Use bornier Ele. 1681 for all operations on the engine management computer
connector.
The oxidation catalytic converter does not produce enough heat at the particle filter inlet to regenerate the particle
filter.
