ET001
COMPUTER + AFTER IGNITION FEED
STATUS DEFINITIONPRESENT, this status indicates that the + after ignition feed is active.
ABSENT, this status indicates that the + after ignition feed is inactive.
NOTESSpecial notes:
Only perform these tests if the statuses do not correspond with the system
programming functions.

AC AUTHORISED
STATUS DEFINITIONYES, this status indicates that the air conditioning is active.
NO, this status indicates that the air conditioning is inactive.
NOTESSpecial notes
Only perform these tests if the statuses do not correspond with the system
programming functions.
Engine running, engine coolant temperature > 80 °C
YES
The 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.
Conformity check with engine stopped and ignition on
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 is activated correctly,
– the air conditioning system feed fuses,
– the presence of refrigerant in the air conditioning circuit,
– that the refrigerant fluid pressure value is consistent at idle speed.
If the fault is still present, check the air conditioning computer faults (see62C, Air
conditioning).
AFTER REPAIRCarry out a road test, then check with the diagnostic tool.

PRE-POSTHEATING UNIT CONTROL
STATUS DEFINITIONACTIVE, when the heater plugs are activated according to the engine coolant
temperature.
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.

Only perform these tests if the statuses do not correspond with the system
programming functions.

"INACTIVE"
After 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.
Sensor conformity check
ACTIVEWhen the vehicle is started from cold, the injection computer controls the pre-
postheating unit so that the vehicle can be started.
Status ET007 becomes YES a few seconds after the ignition is switched on and during
pre/postheating.
If the vehicle does not start and status ET007 becomes YES, check:
– supply fuse F2 (Scénic II and Mégane II) or FM12 (Laguna II) (70A) for the
preheating unit, located on the power supply fuse board in the engine compartment
connection unit, below the Protection and Switching Unit,
– the resistance of the heater plugs.
Replace any plug with a resistance greater than 2Ω.
If the vehicle starts and status ET007 remains YES during the engine operating phase,
refer to the interpretation of faults:
– DF017 Preheating relay control circuit.
– DF025 Pre-postheating unit diagnostic connection.
AFTER REPAIRCarry out a road test, then check with the diagnostic tool.

INACTIVE
After the engine is started and the postheating phase, the injection computer should
stop the pre-postheating unit operating.
Status ET007 should become NO.
In the event that the vehicle does not start and status ET007 remains NO, check the
continuity and absence of interference resistance of the following connections:
– Connection code 3FY,
– Connection code 3FF.
Between components 120 and 257.
If the connection or connections are faulty and 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, refer to the interpretation of faults:
– DF017 Preheating relay control circuit.
– DF025 Pre-postheating unit diagnostic connection.
AFTER REPAIRCarry out a road test followed by a check with the diagnostic tool.

CHECK COOLING FAN 1
STATUS DEFINITIONRUNNING, this status indicates that the fan assembly is engaged.
STOPPED, this status indicates that the fan assembly is not engaged.
NOTESSpecial notes:
Only perform these tests if the statuses do not correspond with the system
programming functions.
NOTE:
Statuses ET014 and ET022 Low-speed fan assembly request change status simultaneously.
Conformity check with the engine stopped and the ignition on, or engine running, and engine coolant
temperature > 80°C
RUNNING
The low-speed engine fan is supplied in three scenarios:
– the engine coolant temperature is greater than 89°C,
– the air conditioning is operating,
– the injection computer has system faults that could lead to the engine overheating.
When the low-speed fan assembly is supplied:
–status ET014 becomes RUNNING and status ET022 Low-speed fan assembly
request becomes ACTIVE.
If the low-speed fan assembly does not work, refer to the fault finding note for the
Protection and Switching Unit (Vdiag 18, 1C, 20 only).
Conformity check with engine stopped and ignition on.
STOPPEDThe low-speed fan assembly stops when:
– the engine coolant temperature is less than 89°C
– the air conditioning is not switched on by the driver.
IMPORTANT!WARNING
If the Protection and Switching Unit (Vdiag 18, 1C, 20 only) no longer detects the injection
computer signals, the low-speed fan assembly is supplied until the battery is completely
discharged.
If the low-speed fan assembly is defective, the high-speed fan assembly will be activated.
AFTER REPAIRCarry out a road test followed by a check with the diagnostic tool.
