NOTESConditions for applying the fault finding procedure to stored faults:
The fault is declared present after a road test.
Special notes:
The EGR function is inhibited if several faults are present with DF226 Damper valve
circuit.
If 1.DEF is present:
– the level 1 warning light is lit,
– the vehicle performance is reduced,
– there is smoke coming from the exhaust.
Use bornier Elé.1681 or Elé.1590 for any operation on the injection computer
connectors.
1.DEF
2.DEF
NOTESNone
Check the EGR valve connections.
Check the injection computer connections.
Repair if necessary.
Check the continuity and absence of interference resistance of the following connections:
– connection code 3VP,
– connection code 3VQ.
between components 120 and 1460.
If the connection or connections are faulty and there is a repair method (see Technical Note 6015A, Repairing
electrical wiring, Wiring: Precautions for repair), repair the wiring, otherwise replace it.
Check that there are no leaks on the EGR circuit, pierced or damaged pipes, and the tightness of the clips.
Measure the resistance of the EGR valve motor between connections 3VP and 3VQ.
Replace the EGR valve if the resistance displayed is not between 1 Ω < X < 400 Ω at 20°C.
If the valve is jammed or irrevocably seized, replace the EGR valve.
Run command SC036 Reinitialise programming and select EGR valve to reinitialise the EGR valve offsets (see
Replacement of components).
AFTER REPAIRDeal with any faults.
Carry out a road test followed by another check with the diagnostic tool.

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.
