ET014FAN ASSEMBLY NO. 1 CHECK
STATUS DEFINITIONRUNNING: This status indicates that the fan assembly is engaged.
STOPPED: This status indicates that the fan assembly is not engaged.
NOTESSpecial notes:
Only perform these tests if the statuses 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
RUNNINGThe low-speed engine fan is supplied in three scenarios:
– the engine coolant temperature is greater than 89°C,
–the air conditioning is operating,
– the injection computer has system faults that could lead to the engine overheating.
When the low-speed fan assembly is supplied:
–status ET014 Fan assembly 1 check becomes RUNNING.
–status ET143 Low speed fan unit relay control becomes ACTIVE.
Conformity check with engine stopped and ignition on
STOPPEDThe low-speed fan assembly stops when:
– the engine coolant temperature is less than 89°C,
– the air conditioning is not switched on by the driver.

ET144
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.

PR053SPEED REQUESTED BY HEATING/AIR CONDITIONING
PARAMETER
DEFINITIONThis parameter indicates the engine's speed of rotation with air conditioning in rpm.
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
Indicates the engine's speed of rotation with air-conditioning in rpm.
PR035 = 0 rpm.
Conformity check with engine running, engine coolant temperature > 80°C
The speed requested by the air-conditioning is increased and varies around 850 rpm.

SC001WRITE SAVED DATA
NOTESTo use this command, first save the data with the SC003 Save computer data
command.
The writing is carried out after the computer has been reprogrammed or replaced.
Ignition on and engine stopped.
Validating this command writes the data saved using command
SC003 Save computer data.
The data is as follows:
– injector codes,
– the egr valve data programming;
options available on the vehicle and managed by the computer (e.g. air conditioning);
This data will configure the computer and will prevent:
– engine malfunction after (re)programming or replacing the computer;
– faulty interpretation of information provided by the CLIP tool.
