NOTESSpecial notes:
This fault appears when the computer control section has
overheated.
– A road test may be necessary.
Priority when dealing with a number of faults:
Deal with the statuses CO, CC.0, and CC.1 first if they are
present or stored.
After any operation on the damper valve, run SC036
Reinitialise programming (see Interpretation of
commands).
Check the condition of the damper valve connector (see Wiring Diagram Technical Note, Mégane II ph2,
Scénic II ph2, component code 1461).
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 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 that the valve is not mechanically jammed:
With the engine stopped, disconnect the air inlet hose from the damper valve.
Check that the valve is in the open position.
Start, then switch off the engine.
Check that the valve closes when the engine is switched off and then opens again when the engine has stopped.
If this does not happen, replace the damper valve.
Check that the valve is clean and that there is no component preventing it from closing (particularly for 2.DEF).
Clean if necessary.
Check the continuity of the following connections:
– Connection code 3VM between components 1461 and 120.
– Connection code 3VN between components 1461 and 120.
Check the insulation against + 5 V and + 12 V (computer feed) of the following connections:
– Connection code 3VM between components 1461 and 120.
– Connection code 3VN between components 1461 and 120.
If there is a repair method (see Technical Note 6015A, Repairing electrical wiring, Wiring: Precautions for
repair), repair the wiring, otherwise replace it.
If the fault is still present, contact the Techline.

AC or AUTO position with minimum ventilation),
– the engine is not under full load,
– the air conditioning system is not faulty.
NOStatus ET004 remains NO under the following conditions:
– Vehicle stopped with the ignition on,
– faults present in the air conditioning circuit,
– no air conditioning request made by the driver,
– engine under full load.
If status ET004 remains NO then the air conditioning should be authorised. Check:

STATUS DEFINITIONACTIVE: when the heater plugs are activated according to the temperature of the
engine coolant.
INACTIVE: after the engine has been running for a certain period.
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.
