ABSENT
NOTESIgnition on
If the ignition is not switched on, the status ET001 must be ABSENT.
As soon as the ignition is switched on, the computer should be supplied with power. The status ET001 becomes
PRESENT.
If this status remains locked on ABSENT, follow the procedure below:
Check the status of fuse FM3 (30A) in the engine fuse and relay box.
Check the continuity and absence of any interference resistance on the following connection:
– connection code 3AA between components 120 and 983.
If the connection is faulty and there is a repair procedure (see Technical Note 6015A, Repairing electrical
wiring, Wiring: Precautions for repair), repair the wiring, otherwise replace it.
Check the condition of the engine management computer connector (see Wiring Diagram Technical Note,
Mégane II ph2, Scénic II ph2, component code 120).
If the connector or connectors are faulty and 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, contact the Techline.
PRESENT
NOTESIgnition on
Normal operating condition.
The computer is correctly supplied after the ignition has been switched on.
AFTER REPAIRCarry out a road test, then check with the diagnostic tool.

YESThe air conditioning authorisation only changes to YES if:
– the air conditioning request has been made by the driver (air conditioning switch in
AC or AUTO position with minimum ventilation),
– the engine is not under full load,
– the air conditioning system is not faulty.
NOStatus ET004 remains NO under the following conditions:
– Vehicle stopped with the ignition on,
– faults present in the air conditioning circuit,

ET143
CONTINUED
Sensor electrical conformity
ACTIVEWhen the coolant reaches 99°C, the injection computer commands the low-speed
relay of the fan assembly, 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.
Disconnect the low speed and high speed relays, check their operation 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 low-speed relay of the fan
assembly:
– Connection 3FB of component 700.
Check the continuity and the absence of interference resistance on the following
connection:
– Connection code 49L between components 700 and 321.
Check the continuity and the absence of interference resistance on the following
connection:
– Connection code 49B between components 262 and 321.
Check the continuity and the absence of interference resistance on the following
connection:
– Connection code 3JN between components 700 and 120.
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.
INACTIVEIf 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 must 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.

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.
