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.

CONTINUED
Conformity check with engine running, engine coolant temperature > 80°C
(heating and air-conditioning off) INACTIVE OR ACTIVE, depending on the engine temperature.
ACTIVEWhen the coolant reaches 102°C, the injection computer commands the low-speed
relay of the fan assembly 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.
– Disconnect the high speed relay of the fan assembly, check it is functioning correctly
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 high-speed fan assembly relay:
– connection 3FB of component 234.
Check the continuity and the absence of interference resistance on the following
connection:
– connection code 3JP between components 234 and 120.
Check the continuity and the absence of interference resistance on the following
connection:
– Connection code 49B between components 234 and 262.
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.
INACTIVEWhen the injection computer no longer requests cooling, the status ET144 changes to
INACTIVE. The fan assembly should then switch off.
AFTER REPAIRCarry out a road test, then check with the diagnostic tool.

STATUS DEFINITIONACTIVE: This status indicates that the thermoplunger is supplied.
INACTIVE: This status indicates that the thermoplunger is not supplied.
NOTESStatus only available on certain Vdiag48 (depending on vehicle equipment).
INACTIVEStatuses ET205, ET206, ET207 are INACTIVE with the ignition on and the engine
stopped, or when the engine is warm.
ACTIVEStatuses 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:
DF032 Thermoplunger 1 relay control circuit.
DF033 Thermoplunger 2 relay control circuit.
DF034 "Heating element 3 relay control circuit".

DESCRIPTION OF THE PROCESS
Particle filter regeneration takes place in 3 stages (values given as a guide only):
–Heating phase: the engine speed is fixed or fluctuating around 2000 rpm.
This phase lasts between 8 and 14 minutes, until the coolant temperature exceeds 70°C.
–Regeneration phase: the speed is fixed or varies around 2000 rpm. Engine injection is retarded. The exhaust
fumes rise in temperature and burn the soot retained in the particle filter. Then the combustion of the soot stored
in the particle filter causes the particle filter upstream temperature to increase, possibly reaching 600°C
depending on the amount of soot in the particle filter. This phase lasts 28 minutes.
–Cooling phase: the engine speed decreases to 1250 rpm then increases to 1750 rpm.
Engine injection returns to normal and the exhaust gases cool the particle filter.
This phase lasts 3 minutes.
The procedure lasts at least 40 minutes, and varies depending on the time taken to reach a coolant temperature
of 70°C.
VALIDATING THE REGENERATION PROCESS:
At the end of regeneration, a message appears to announce whether the regeneration was successful:
●Particle filter regeneration finished:
Consult PR1012 Weight of soot after regeneration. If PR1012 is less than 15 g, the particle filter regeneration
completed correctly. If PR1012 is greater than 15 g, a second particle filter regeneration must be performed using
the command in the diagnostic tool and choose command SC017.
