– a road test followed by a power latch phase.
Special notes:
The level 1 and EOBD (European On Board Diagnostic) warning lights are lit.
If the fault is stored, clear the fault from the computer memory.
In the main screen of the CLIP diagnostic tool, note the injector codes.
Clear the computer memory using command RZ034 Computer memory.
Switch off the ignition, wait for the diagnostic tool message (maximum wait 8 min): Loss of dialogue with the
computer: EDC16 CP33, check the tool connection and the computer supply voltage then switch on the
ignition again.
Switch on the ignition and re-establish dialogue.
If the fault is still present, contact the Techline.
If the fault is no longer present, carry out the programming (see Programming).
Switch off the ignition, wait for the diagnostic tool message (maximum wait 8 min): Loss of dialogue with the
computer: EDC16 CP33, check the tool connection and the computer supply voltage then switch on the
ignition again.
For vehicles equipped with a particle filter:
– Check the exhaust pipe for leaks or blockage. Repair if necessary.
– Carry out a particle filter regeneration using command SC017 Particle filter regeneration (see Interpretation
of commands) and perform an oil change if the vehicle is not new.

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:
– particle filter regeneration is inhibited,
– blue/white smoke and black particles coming from the exhaust,
– the EOBD (European On Board Diagnostic) warning light will come on after three
consecutive driving cycles (starting + 5 seconds + switch off the ignition and wait
40 seconds).
–The level 1 warning light is lit (for Vdiag 20, 24, 58, 5C, 26, 28, 60 and 62).
Priorities when dealing with a number of faults:
– DF315 Particle filter diff. pressure sensor if present or stored.
– DF717 Particle filter upstream pressure if it is present or stored.
NOTE:
In the long term, this fault may lead to premature wear and a greater risk of turbocharger
failure.
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.

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.

Check the condition of the EGR valve (see Wiring Diagram Technical Note, Laguna II ph2, Vel Satis ph2,
Espace IV ph2, Mégane II ph2, Scénic II ph2, component code 1460 or 169).
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.
Measure the resistance between connections 3EL and 3JM of component 1460 or 169.
If the resistance of the EGR valve is not between 1 kΩ < X < 7,5 kΩ, replace the EGR valve.
Measure the resistance between connections 3EL and 3GC of component 1460 or 169.
If the resistance of the EGR valve is not between 3.9 kΩ < X < 12.6 kΩ, replace the EGR valve.
After replacement, run command SC036 Reinitialise programming and select EGR valve to reinitialise the EGR
valve offsets.
Check the continuity and absence of interference resistance of the following connections:
•3GC between components 120 and 1460 or 169,
•3EL between components 120 and 1460 or 169,
•3JM between components 120 and 1460 or 169.
If the connection or connections are faulty and if there is a repair method (see Technical Note 6015A, Electrical
wiring repair, Wiring: Precautions for repair), repair the wiring,
otherwise replace the wiring.
Remove and clean the EGR valve, then refit the EGR valve and start the engine (see MR364 (Mégane II ph2),
MR370 (Scénic II ph2), MR 395 (Laguna II ph2), 402 (Vel Satis ph2), 405 (Espace IV ph2), Mechanical, 14A,
Emission control, Exhaust gas recirculation solenoid valve: Removal - Refitting).
If the fault is still present, replace the EGR valve then run command SC036 Reinitialise programming and select
EGR valve to reinitialise the EGR valve offsets.
