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.
AFTER REPAIRCarry out a road test, then check with the diagnostic tool.

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.

STATUS
DEFINITIONACTIVE: This status indicates that the thermoplunger is supplied.
INACTIVE: This status indicates that the thermoplunger is not supplied.
NOTESNone.
"INACTIVE"Statuses ET205, ET206, ET207 are INACTIVE when the ignition is switched on
and the engine stopped, or when the engine is warm.
"ACTIVE"Statuses ET205, ET206 and ET207 are ACTIVE when the engine is started, the
engine coolant temperature is low (<15°C) and the air temperature is low (<5°).
This program allows the engine coolant to be heated to enable the passenger
compartment to be heated.
The thermoplungers also act both to load the engine to improve regeneration of
the particle filter.
To control the operation of the thermoplunger relays, run the following commands:
– AC063 Thermoplunger no.1 relay,
– AC064 Thermoplunger no. 2 relay,
– AC031 Thermoplunger no.3 relay.
In the event of a fault, refer to the interpretation of faults:
– DF034 "Thermoplunger 3 relay control circuit",
– DF033 "Heating element 2 relay control circuit",
– DF032 Thermoplunger 1 relay control circuit.

NOTESPerform this fault finding procedure:
– following interpretation of an unresolved fault or,
– following application of the interpretation of PR041 Turbocharging pressure or
– after a customer complaint (loss of power, smoke etc.).
Use the Wiring Diagram Technical Note, Laguna II ph2, Vel Satis ph2, Espace IV

1. The following procedure is for checking that the turbocharger and its control circuit are working
properly.
Preliminary operation
Check the high pressure air circuit is sealed:
Apply Test 4 Turbocharged air inlet circuit check or Test 3 Low pressure circuit check.
Pipe not joined or pierced, pressure sensor disconnected or poorly fitted (seal present), exchanger pierced.
To test the exchanger: stabilise the engine speed between 3500 and 4000 rpm with the vehicle stopped and
check that there are no leaks.
Measure the resistance between connections3FB and 3MG of component1475.
If the resistance is not between 18 Ω and 22 Ω at + 23°C, replace the turbocharging solenoid valve.
Check the continuity of the following connection:
•3MG between the components 120 and 1475.
Check the + 12 V after relay supply of the turbocharging solenoid valve on the following connection:
•3FB of component 1475.
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.
