Sensor electrical conformity
YESThe air conditioning authorisation only changes to YES if:
– the air conditioning request has been made by the driver (air conditioning switch in
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:
– that the air conditioning compressor starts correctly,
– the air conditioning system supply fuses,
– the presence of refrigerant in the air conditioning circuit,
If the fault is still present, check the air conditioning computer faults (see 62B, Air
conditioning).
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

ET007PRE-POSTHEATING UNIT CONTROL
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.

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.
