AFTER REPAIRDeal with any other faults. Clear the fault memory.
Switch off the ignition until the end of the power-latch phase, and carry out a road test
followed by a check using the diagnostic tool.

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 OBD warning light will illuminate after three consecutive driving cycles (start + 5
seconds, switch off the ignition and wait 40 seconds).
Priorities when dealing with a number of faults:
– DF315 Particle filter diff.* pressure sensor if present or stored
IMPORTANT
In the long term, this fault may lead to premature wear and a greater risk of
turbocharger failure.
Use Wiring Diagram Technical Note, Mégane II ph2, Scénic II ph2.

The continuity and absence of interference resistance on the following
connections:
– Connection code 37AB between components 257 and 683,
– Connection code 37AA between components 257 and 680,
– Connection code 37Z between components 257 and 681,
– Connection code 37AC between components 257 and 682.
If the connection or connections are faulty and there is a repair procedure (see
Technical Note 6015A, Electrical wiring repair, Wiring: Precautions for repair),
repair the wiring. Otherwise replace the wiring.
Check the status of the preheating unit and that they are connected correctly (see
Wiring Diagram Technical Note, Mégane II ph2, Scénic II ph2, Component code
257).
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.
If the vehicle starts, postheating has ended and status ET007 remains ACTIVE during
the engine operating phase, consult the interpretation of faults DF017 'Preheating
unit control circuit'' and DF025 Preheating unit diagnostic line (see
Interpretation of faults).
INACTIVEIf the vehicle does not start, the status remains INACTIVE and preheating was not
executed when the ignition was switched on or during the starting phase.
Check the continuity and absence of interference resistance on the following
connections:
– Connection code 3FY, between components 120 and 257.
– Connection code 3FF between components 120 and 257.
Check the + 12 V battery supply to the pre-postheating unit.
– Connection code BP35 of component 257.
If the connection or connections are faulty and there is a repair procedure (see
Technical Note 6015A, Electrical wiring repair, Wiring: Precautions for repair),
repair the wiring. Otherwise replace the wiring.
Conformity check with engine running, engine coolant temperature > 80°C

then
INACTIVEAfter the engine has been running for a certain period, the status changes from
ACTIVE to INACTIVE.
In the event of a fault, consult the interpretation of fault DF017 Preheating unit
control circuit.
AFTER REPAIRDeal with any other faults. Clear the fault memory.
Switch off the ignition and carry out a road test followed by a test with the diagnostic
tool.
