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 parameters do not correspond with the system
operation programming.
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
"NO"The status is usually NO as no impact has been detected.
Otherwise, check the airbag computer (see88C, Airbags and pretensioners).
"YES"If YES an impact must be present.
Otherwise, check the airbag computer (see88C, Airbags and pretensioners).
After the repair, clear the faults (even if no fault is displayed).

ET143LOW-SPEED FAN ASSEMBLY RELAY CONTROL
STATUS
DEFINITIONThis status indicates whether the low speed fan assembly is active.
NOTESSpecial notes:
Only perform these tests if the parameters do not correspond with the system
operation programming.
If the vehicle is fitted with air conditioning, the fan assembly electrical circuit includes
2 relays. The 1
st speed fan assembly relay will be actuated when the engine coolant
temperature exceeds 99°C and its function is to cool the engine so that the engine
temperature does not exceed 102°C. If the engine coolant temperature exceeds 102°C,
the 2
nd speed fan assembly relay will be actuated and the fan will rotate faster.
Use the Wiring Diagram Technical Note, Laguna II ph2, Vel Satis ph2, Espace IV
ph2, Mégane II ph2, Scénic II ph2.
IMPORTANT:
If the vehicle is equipped with air conditioning, the engine cooling fan will operate at 1
st speed as soon as the air
conditioning compressor is activated.
Conformity check with engine stopped and ignition on.
"INACTIVE"Engine cold and air conditioning switched off
In the event of a fault, consult the interpretation of fault DF018 Low speed fan
assembly control circuit.

INACTIVE or ACTIVE, depending on the engine temperature (air conditioning switched off).
In the event of a fault, refer to the interpretation of fault DF018.
Sensor electrical conformity
"ACTIVE"When the coolant reaches 99°C, the injection computer actuates the low-speed fan
assembly relay, 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 (see MR364
(Mégane II ph2), MR370 (Scénic II ph2), MR 395 (Laguna II ph2), 402 (Vel Satis
ph2), 405 (Espace IV ph2) Mechanical, 81C, Fuses, Fuses: List and location of
components).
Disconnect the low speed and high speed relays, check that they are operating
correctly and check the condition of the relay mounting connectors (see Wiring
Diagram Technical Note, Laguna II ph2, Vel Satis ph2, Espace IV ph2, Mégane II
ph2, Scénic II ph2, component code 597).
If one of the connectors is faulty and there is a repair procedure (see Technical
Note 6015A, Electrical wiring repair, wiring: precautions for repair), repair the
connector, otherwise replace the wiring.
Check the + 12 V after relay supply to the low speed fan assembly relay on the
following connection:
•3FB of component 700.
Check the continuity and absence of interference resistance of the following
connections:
•49L between components 700 and 321,
•49B between components 262 and 321,
•3JN between components 700 and 120.
AFTER REPAIRCarry out a road test, then check with the diagnostic tool.

"ACTIVE"
Check that the earth is in order on connection MAS 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 it.
"INACTIVE"If 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 should therefore be INACTIVE when the control relay and the engine
cooling fan are not supplied.

ET144HIGH-SPEED FAN ASSEMBLY RELAY CONTROL
STATUS
DEFINITIONThis status indicates whether the high speed fan assembly is active.
NOTESSpecial notes:
Only perform these tests if the parameters do not correspond with the system
operation programming.
If the vehicle is not fitted with air conditioning, low-speed fan assembly relay does not
exist. The circuit therefor only contains a single command relay to supply the engine
cooling fan. The engine cooling fan will thus have only one operating speed.
Use the Wiring Diagram Technical Note, Laguna II ph2, Vel Satis ph2, Espace IV
ph2, Mégane II ph2, Scénic II ph2.
Conformity check with engine stopped and ignition on.
"INACTIVE"Engine cold and air conditioning switched off
In the event of a fault, consult the interpretation of fault DF019 High speed fan
assembly control circuit.
Conformity check with the engine running and engine coolant temperature > 80°C
INACTIVE or ACTIVE, depending on the engine temperature (air conditioning switched off).
In the event of a fault, refer to the interpretation of fault DF019.
