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.
NOTESSpecial notes:
Only perform these tests if the statuses do not correspond with the system
programming functions.
Conformity check with engine running, engine coolant temperature > 80 °C
"ACTIVE"
Then
"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.

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.

Starting the vehicle is authorised when the UCH authorises starting.
Status ET076 changes to AUTHORISED if the vehicle cards are recognised and if the
engine immobiliser is inactive.
PROHIBITEDIf the card is not recognised by the UCH, starting the vehicle is prohibited.
Status ET076 is PROHIBITED and the vehicle cannot be started.

IMPACT DETECTED
STATUS DEFINITIONNO: This status indicates that the airbag computer has not detected an impact.
YES: This status indicates that the airbag computer has detected an impact.
NOTESSpecial notes:
Only perform these tests if the statuses do not correspond with the system
programming functions.
This signal is transmitted by the airbag computer via the multiplex network.
Conformity check with the engine stopped and the ignition on, or engine running, and engine coolant
temperature > 80°C
NO
Under normal operating conditions, status ET077 is NO when the computer has
received no impact signal.
YESIf the vehicle has had an accident, the injection computer receives the impact signal via
the multiplex network and may switch off the ignition. Status ET077 is YES.
Switch off the ignition for 1 minute, then switch it on again, so the engine can be
started.
Carry out a multiplex network test and deal with any faults.
Clear the injection computer faults, even if no fault is present.
AFTER REPAIRCarry out a road test, then check with the diagnostic tool.
