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.

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.

PR053SPEED REQUESTED BY HEATING/AIR CONDITIONING
PARAMETER
DEFINITIONThis parameter indicates the engine's speed of rotation with air conditioning in rpm.
NOTESSpecial notes:
Only perform these tests if the parameters do not correspond with the system
operation programming.
Note:
Take parameter PR053 into account only if PR037 Refrigerant pressure > 12 bar.
Conformity check: Engine stopped and ignition on
The value of the engine speed with air conditioning must be:
PR053 = 0 rpm (ignition on).
Conformity check with the engine running and engine coolant temperature > 80°C
The speed requested by the air-conditioning is increased and varies around 850 rpm.

SC017PARTICLE FILTER REGENERATION
NOTESOnly run this command after interpretation of the following faults:
– DF308 Clogged particle filter,
– DF311 Failed regenerations limit exceeded,
– df312: speed request.
WARNING:
– It is essential to observe the health and safety guidelines (see MR364 (Mégane II ph2), MR370 (Scénic II ph2),
MR 395 (Laguna II ph2), 402 (Vel Satis ph2), 405 (Espace IV ph2) Mechanical, 19B, Exhaust, Particle
filter: Cleaning) and follow the procedure below.
SAFETY INSTRUCTIONS TO BE FOLLOWED:
The regeneration causes exhaust fumes and high temperatures.
It is strongly recommended that you put the vehicle outside during regeneration.
If it is not possible to carry out regeneration outside, use an extractor fan that can withstand the very high
regeneration temperatures (400°C at the exhaust outlet).
Perform regeneration on a surface free from fire risks (oil, dry leaves, etc.).
Nothing should be left in the vicinity of the exhaust pipe.
Check that there are no leaks or blockages in the exhaust pipe,
Repair if necessary.
WARNING:
Check the engine oil level before running the command to avoid any engine racing. The oil level must be
between the minimum level and the middle level on the oil dipstick.
Before performing a particle filter regeneration, it is essential to deactivate the air conditioning
compressor (risk of engine damage) and all the electrical consumers.
IF NECESSARY:
Regeneration can be stopped by pressing the engine start button twice briefly (less than 3 seconds).
Switch off the ignition and wait for the diagnostic tool message (maximum time 8 minutes) Communication
lost with computer: EDC16 C33, check the tool connection and the computer power supply before
switching the ignition back on.

RZ005PROGRAMMING
NOTESSpecial notes:
this command enables you to reinitialise the entire computer configuration according to
the vehicle.
Command RZ005 reconfigures the computer.
If the computer does not have any configuration data, use command RZ005 to enter the vehicle options:
– air conditioning,
– Passenger compartment heating resistor,
– cruise control/speed limiter.
These options are detected by the computer even if command RZ005 is not used.
The computer is configured as soon as the one of the vehicle's optional system components is operated.

Laguna II ph2, Vel Satis ph2, Espace IV ph2 only.
AC154LOW-SPEED FAN ASSEMBLY
NOTESThere must be no present or stored faults.
Perform this fault finding after an engine cooling fault or air conditioning fault.
Engine stopped.
Use the Wiring Diagram Technical Note for Laguna II ph2, Vel Satis ph2, Espace
IV ph2.
If, when running command AC154, the low speed fan assembly relay does not operate:
Check the condition of the low speed fan assembly relay mounting connectors (see Wiring Diagram Technical
Note, Vehicle, 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.
If the fault is still present, check that the relay is actuated by the engine management computer as follows:
Disconnect the low speed fan assembly relay, fit a 50 Ω to 100 Ω resistor on the relay mounting in place of the
coil, and connect a voltmeter as follows:
– positive terminal to + 12 V battery,
– negative terminal to connection 3JN of component 700.
Run command AC154.
If the voltmeter shows the battery voltage (4 ON-OFF cycles of 10 seconds), replace the relay.
If the voltmeter does not show the battery voltage (4 ON-OFF cycles of 10 seconds), contact the Techline.
If the low speed fan assembly relay is supplied using command AC154, but there is still a fan assembly actuation
fault, use the wiring diagram to check:
The conformity of the fan assembly maxi-fuse.
– Check the continuity of connection 49L between components 700 and 321.
– Check the low speed resistor (resistance and connections).
– Check the continuity of connection 49B between components 262 and 321.
– Check for complete earthing on connection MAS of component 162.
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.
