NOTESThere must be no present or stored faults.
Perform this fault finding procedure:
– after an inconsistency appears on the Parameter screen,
– following the activation of command AC003 Fuel pressure solenoid valve,
– following a customer complaint (starting problems, poor performance, stalling, etc.).
Use CLIO III, MODUS, MEGANE II ph2, SCENIC II ph2 and KANGOO II Wiring
Diagrams Technical Notes.
Conformity check with the engine stopped and the ignition on, or the engine running and the engine
coolant temperature > 80°C

–3LX between components 1032 and 120,
–3LY between components 1032 and 120,
–3LZ between components 1032 and 120.
If the connection(s) 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.
If all these connections are correct, check for the fuel pressure sensor supply:
+ 5 V on connection code 3LX between components 1032 and 120,
Earth on connection code 3LZ between components 1032 and 120.

wiring, Wiring: Precautions for repair), repair the wiring, otherwise replace it.
Check the low and high pressure diesel circuit sealing (visual checks, odours): on pump body, pressure release
valve, pipes, rail and injector unions, injector wells, etc.
If all the above checks are correct:
With the vehicle ignition on, and engine stopped for over 1 minute:
Display PR038; if the value is lower than 30 bar, the sensor is correct.
Otherwise replace the rail pressure sensor (see MR 392, 385, 364, 370
and 417 Mechanical, 13B, Diesel
injection, Rail pressure sensor: Removal - Refitting).

PARTICLE FILTER REGENERATION
NOTESCarry out this command only under the following conditions:
– DF308 Clogged particle filter present.
Ignition on and engine stopped.
Vdiag 45, 49 and 4D only.
WARNING:
–It is essential to carry out the next procedure in accordance with the safety and cleanliness guidelines,
(see MR 364 (Mégane II), 370 (Scénic II), 417 (Kangoo II), 385 (Modus), 392 (Clio III), Mechanical, 19B,
Exhaust, Particle filter: Cleaning).
– do not run command AC029 High pressure circuit seal test until regeneration has finished.
– before each regeneration, check the fuel level,
– before and after each regeneration, check the oil level.
With the engine running and the vehicle stopped, this function allows the particle filter to be regenerated.
Safety instructions to be followed:
The regeneration causes exhaust fumes and high temperatures.
The vehicle must be outside during regeneration.
If it is not possible to carry out regeneration outside, check that the extractor fan can withstand the very high
regeneration temperatures.
Perform regeneration on a surface free from fire risks (oil, dry leaves, etc.).
Nothing should be left in the vicinity of the exhaust pipe.
Before regeneration:
– Respect After-Sales recommendations for particle filter regeneration.
– Check the oil level to prevent the engine from racing.
– Check the fuel level.
– Check the sealing on the 5th particle filter injector circuit using actuator AC237 Fuel pump relay.
– Check that there are no leaks or blockages in the exhaust pipe,
To perform regeneration:
– Vehicle stopped and in neutral.
– Engine running and warm.
– No pedal depressed (accelerator and clutch).
– No faults present preventing regeneration from being carried out on the system.
– No leak in the 5th particle filter injector circuit.
AFTER REPAIRDeal with any faults displayed by the diagnostic tool.
Clear the computer fault memory.
Carry out a road test followed by another check with the diagnostic tool.
