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.

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

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.

ET238SYNCHRONISATION
STATUS
DEFINITIONSynchronisation is carried out during the engine starting phase. The camshaft position
sensor and the TDC sensor are synchronised. Once this synchronisation has been
carried out, it enables the computer to identify cylinder n°1 and to ascertain the precise
position of the cylinder's top dead centre.
Synchronisation also allows the computer to determine the injection strategy.
NOTESSpecial notes:
Only perform these tests if the parameters do not correspond with the system
operation programming.
Conformity check with engine stopped and ignition on, or engine running, and engine coolant
temperature > 80°C
COMPLETEDStatus ET238 is DONE when the engine is started. The computer has identified
cylinder no. 1 and has identified the exact top dead centre position. Injection
phasing and engine management are now possible, and the engine should be
working properly.
NOT
COMPLETEDStatus ET238 is NOT COMPLETED when the engine has been stopped with the
+ after ignition feed on.
If status ET238 remains NOT COMPLETED after an attempted start, consult the
interpretation of fault DF195 Camshaft sensor/engine speed consistency.
