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.

"ACTIVE"When the coolant reaches 102°C, the injection computer actuates the fan assembly
relay and status ET144 becomes ACTIVE. The relay then supplies the cooling fan.
If status ET144 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 high-speed fan assembly relay on the
following connection:
•3FB of component 234.
Check the continuity and absence of interference resistance of the following
connections:
•3JP between components 234 and 120,
•49B between components 234 and 262.
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.
AFTER REPAIRCarry out a road test, then check with the diagnostic tool.

NOTESSpecial 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
PRESENTThere is a multiplex connection between the injection computer and the automatic
transmission computer.
ABSENTThere is no multiplex connection between the injection computer and the automatic
transmission computer, as there is a manual gearbox.
If there is an automatic transmission and the message ABSENT appears:
Run a multiplex network test (see 88B, Multiplex).
Check the continuity and insulation to earth of the following connections:
•3MS and 3MT between components 119 and 120.
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"Status ET703 becomes INACTIVE when none of the cruise control / speed limiter
buttons is pressed. These buttons are located on the steering wheel.
If status ET703 does not display INACTIVE,
– check the condition of the cruise control / speed limiter +/- button and the condition
of its connector,
– check the condition of the cruise control / speed limiter R/0 button and the condition
of its connector.
"PLUS"Status ET703 becomes PLUS when the cruise control / speed limiter + button is
pressed. This button is on the steering wheel, on the left-hand side.
If status ET703 does not display INCREASE, check the condition of the cruise
control/speed limiter +/- button and the condition of its connector. Repair if necessary.
To perform these checks and measurements in complete safety, observe the
recommendations for removing the driver's front airbag (see MR Mechanical, 88C,
Airbag and pretensioners, Driver's front airbag: Removal - Refitting).
Measure the resistance of the following connections while pressing the + button
(on the button connections):
•86G of component 331,
•86M of component 331.
If the connection or connections are faulty and there is a repair procedure
(seeTechnical Note 6015A, Electrical wiring repair, Wiring: Precautions for
repair), repair the wiring, otherwise replace it.
If the resistance is not approximately 300 Ω, check the continuity of the connection
when the button is not pressed.
If there is continuity, replace the +/- control button.
If the connection or connections are faulty and there is a repair procedure
(seeTechnical Note 6015A, Electrical wiring repair, Wiring: Precautions for
