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.

Sensor electrical conformity
"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.

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.

STATUS
DEFINITIONYES: This status indicates that the immobiliser code has been programmed.
NO: This status indicates that the immobiliser code has not been programmed.
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
"YES"Status ET341 is YES if dialogue is possible between the UCH computer and the
injection computer and the key code is recognised
.
The engine is only authorised to start if the code is correctly recognised by the UCH
computer and statusET003 Engine immobiliser is INACTIVE.
In the event of a fault, (see 87B, Passenger compartment connection unit,
Conformity check).
"NO"Status ET341 is NO if dialogue is not possible between the UCH computer and the
injection computer (status ET003 remains ACTIVE).
This fault may be caused by incorrect key programming or a lack of key programming.
In this case, refer to the UCH fault-finding note (see 87B, Passenger compartment
connection unit) and follow the key programming procedure.
If the key programming is not the cause, run a multiplex network test (see 88B,
Multiplexing) and check that dialogue between the UCH and the injection
computer is possible.
If dialogue is not established, contact Techline.
