ET077IMPACT 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 engine stopped and ignition on, or engine running, and engine coolant temperature
> 80°C
NOThe status is usually NO as no impact has been detected.
Otherwise, check the airbag computer (see 88C, Airbags and pretensioners).
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 10 seconds, then switch it back on, so the engine can be
restarted.
Clear the faults (even if no fault is present or stored).
Otherwise, check the airbag computer (see 88C, Airbags and pretensioners).

– either the SC002 Enter injector codes control,
– or command SC001 Enter saved data when replacing with a blank computer or
after reprogramming.
(Consult the procedures defined in the Interpretation of commands section).
YESWhen the injector codes are programmed.

– either the SC002 Enter injector codes control,
– or command SC001 Enter saved data when replacing with a new computer or
after reprogramming.

ET120PRE-POSTHEATING SIGNAL
STATUS DEFINITIONPRESENT: This status indicates that the pre-postheating signal is still active.
ABSENT: This status indicates that the pre-postheating signal is not active.
NOTESTest the battery and run fault finding on the charging circuit (see Technical Note
6014A, Checking the charging circuit).
Special notes:
Only perform these tests if the statuses do not correspond with the system
programming functions.
Conformity check with engine stopped and ignition on, or engine running, and engine coolant temperature
> 80 °C
PRESENTStatus ET120 is PRESENT when preheating is activated.
ABSENTThe status ET120 is ABSENT as long as pre-postheating is not activated. See
interpretation of faults DF025 Preheating unit diagnostic line and DF017
Preheating unit control circuit.

STATUS DEFINITIONThis status indicates whether the low speed fan assembly is active.
NOTESSpecial notes:
Only perform these tests if the statuses do not correspond with the system
programming functions.
If the vehicle is equipped with air conditioning, the engine cooling fan will operate at 1st
speed as soon as the air conditioning compressor is activated.
Use the Mégane II ph2, Scénic II ph2 Technical Note wiring diagram.
Conformity check with engine stopped and ignition on
INACTIVEEngine cold and air conditioning switched off
Conformity check with engine running, engine coolant temperature > 80°C
(heating and air-conditioning off) INACTIVE OR ACTIVE, depending on the engine temperature.

ET143
CONTINUED
Sensor electrical conformity
ACTIVEWhen the coolant reaches 99°C, the injection computer commands the low-speed
relay of the fan assembly, and status ET143 becomes ACTIVE. The relay then
supplies the fan assembly and the cooling fan begins to turn.
If status ET143 is ACTIVE, but the cooling fan is not running, perform the following
operations:
– Check the condition of fuse FM15 (60 A) in the engine fuse and relay box.
Disconnect the low speed and high speed relays, check their operation and the status
of the connectors of the relay mounting (see Wiring Diagram Technical Note,
Mégane II ph2, Scénic II ph2, Component code 597).
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.
Check for the supply of + 12 V after the relay to the low-speed relay of the fan
assembly:
– Connection 3FB of component 700.
Check the continuity and the absence of interference resistance on the following
connection:
– Connection code 49L between components 700 and 321.
Check the continuity and the absence of interference resistance on the following
connection:
– Connection code 49B between components 262 and 321.
Check the continuity and the absence of interference resistance on the following
connection:
– Connection code 3JN between components 700 and 120.
Check that the earth is in order on the MAS connection of component 262.
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.
INACTIVEIf the engine temperature is lower than 99°C, the engine cooling fan cannot switch on
and the low speed fan relay of the cannot be run.
Status ET143 must therefore be INACTIVE when the control relay and the engine
cooling fan are not supplied.
AFTER REPAIRCarry out a road test, then check with the diagnostic tool.
