Check the status of the differential pressure sensor connector and engine management computer.
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.
Check the particle filter is present.
If it is present,
Visually check that the particle filter is in good condition by positioning the vehicle on a lift:
– not damaged (no abnormal welds, if necessary compare it with another vehicle fitted with particle filter),
– if there are After-Sales sleeves, as a result of a previous operation, check that the particle filter's contents were
not emptied out when it was removed.
If the particle filter is not in good condition or is absent:
– Replace the particle filter.
– Switch on the ignition.
– establish dialogue with the injection computer,
– run command SC036 Reinitialise programming,
–select After particle filter replacement as the operation type, then follow the instructions given by the
diagnostic tool,
– switch off the ignition,
– wait for the diagnostic tool message (maximum time 8 minutes): Communication lost with computer:
EDC16C36, check the tool connection and computer supply before switching the ignition back on.
– clear the faults from the computer memory (this operation must be carried out within 3 minutes of the ignition
being switched on).
– Check the weight of soot: PR383 Weight of soot in the particle filter.
– If PR383
≥ 1 g. Apply the procedure of test 12 Manual clearing of the weight of soot.
If the fault is still present, contact the Techline.

1. DEF: Above maximum threshold
NOTESConditions for applying the fault finding procedure to a stored fault:
The fault is declared present after:
– the engine is started.
– a road test.
Special notes:
If the fault is present:
– particle filter regeneration is inhibited.
Use bornier Elé. 1681 for any operations on the injection computer connectors.
Use Wiring Diagram Technical Note, Mégane II ph2, Scénic II ph2.
Note:
This fault is activated in case of considerable oil dilution due to a significant number of particle filter regenerations.
Carry out the following:
– An oil change (see MR 364 (Mégane II) or MR 370 (Scénic II), Mechanical, 10A Engine and peripherals,
Engine oil: Draining – Filling),
– reset the oil wear meter,
– clear the faults.
Reset the oil wear meter after the oil change:
It will be necessary to reinitialise the display of the trip computer.
With the ignition on:
– hold down the TC* button for 5 s.
Re-initialisation has worked when the on-board computer no longer displays the key.
If this is not the case, restart the procedure.
Specific case:
If an oil change is performed before the oil service interval warning is exceeded, reinitialise the display.

NOTESIgnition on
If the ignition is not switched on, the status ET001 must be ABSENT.
As soon as the ignition is switched on, the computer should be supplied with power. The status ET001 becomes
PRESENT.
If this status remains locked on ABSENT, follow the procedure below:
Check the status of fuse FM3 (30A) in the engine fuse and relay box.
Check the continuity and absence of any interference resistance on the following connection:
– connection code 3AA between components 120 and 983.
If the connection is faulty and there is a repair procedure (see Technical Note 6015A, Repairing electrical
wiring, Wiring: Precautions for repair), repair the wiring, otherwise replace it.
Check the condition of the engine management computer connector (see Wiring Diagram Technical Note,
Mégane II ph2, Scénic II ph2, component code 120).
If the connector or connectors are faulty and there is a repair procedure (see Technical Note 6015A, Repairing
