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,
– no air conditioning request made by the driver,
– engine under full load.
If status ET004 remains NO then the air conditioning should be authorised. Check:
– that the air conditioning compressor starts correctly,
– the air conditioning system supply fuses,
– the presence of refrigerant in the air conditioning circuit,
If the fault is still present, check the air conditioning computer faults (see 62B, Air
conditioning).
AFTER REPAIRDeal with any other faults. Clear the fault memory.
Switch off the ignition and carry out a road test followed by a test with the diagnostic
tool.

Sensor electrical conformity
NOT DETECTEDIf the vehicle is not fitted with cruise control/speed limiter function buttons, status
ET042 is permanently NOT DETECTED. This confirms that the cruise control/speed
limiter function is not present on the vehicle.
If the vehicle is fitted with cruise control or speed limiter function buttons and the main
switch is in the rest (or neutral) position and the injection computer has just been
programmed or reprogrammed, then status ET042 is NOT DETECTED.
To activate the cruise control or speed limiter function, press the main switch in the
cruise control position and then in the speed limiter position.
Return to rest position
For status ET042: the tool displays INACTIVE.
If not, several steps must be checked:
1. return to the multiplex network test page on the CLIP application. Repeat the
multiplex network test. Re-establish dialogue with the injection computer. Check
ET042. If ET042 is INACTIVE, the injection computer has detected the various
positions of the main switch. The cruise control/speed limiter is active.
2. If status ET042 is still NOT DETECTED, check that the vehicle's owner has not
had the cruise control/speed limiter function disabled in the past. Contact the
Techline.
AFTER REPAIRCarry out a road test, then check with the diagnostic tool.

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.

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 statuses do not correspond with the system
programming functions.
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
PERFORMEDStatus ET238 is NOT COMPLETED if the engine has been stopped with the + after
ignition on.
If status ET238 remains NOT COMPLETED after an attempted start, consult the
interpretation of fault DF195 Camshaft sensor/engine speed consistency.
