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.

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

In the event of a fault, consult the interpretation of fault DF017 Preheating unit control
circuit.
NOTESSpecial notes:
Only perform these tests if the statuses do not correspond with the system
programming functions.
Use the Mégane II ph2, Scénic II ph2 Technical Note wiring diagram.
Conformity check with engine stopped and ignition on
ACTIVEWhen the ignition is switched on, the status ET007 must have an ACTIVE status for a
time that varies depending on the temperature of the engine coolant. Both the relay
and the heater plugs are supplied.
After starting, the status should remain ACTIVE for a time that varies depending on
the engine temperature. This is the postheating phase.
If ET007 is INACTIVE when the ignition is switched on, check:
– The supply fuse FM12 (70A) in (597) the engine fuse and relay box.
– The feed to the heater plugs after relay actuation, and the connections of the heater
plugs.
IMPORTANT
On this engine, the plug supply voltage is variable.
