AC AUTHORISED
NOTESOnly perform the tests if the statuses do not correspond with the system programming
functions.
YES
NO
The 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.
The status ET004 remains at NO" in 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 at NO then the air conditioning should be authorised, check:
– that the air conditioning compressor is activated correctly,
– the air conditioning system feed fuses,
– for gas in the air conditioning circuit,
– the gas pressure value is consistent at idle speed.
If the fault is still present, check the air conditioning computer for faults (See 62A, Air
conditioning).
AFTER REPAIRCarry out a road test followed by another check with the diagnostic tool.

PRE-POSTHEATING UNIT CONTROL
NOTESOnly perform the tests if the statuses do not correspond with the system programming
functions.
YES
NO
When the vehicle is started from cold, the injection computer controls the pre/postheating
unit so that the vehicle can be started.
Status ET007 changes to YES a few seconds after the ignition is switched on and during
pre/postheating.
If the vehicle does not start and status ET007 changes to YES, check:
–the F2 (70A) supply fuse on the preheating unit,
– the resistance of the heater plugs.
Replace any plugs with a resistance greater than 2 Ω.
If the vehicle starts and the status ET007 remains YES during the engine functional
stage, refer to the interpretation of faults:
DF017 Preheating relay control circuit.
DF025 Pre-postheating unit diagnostic connection.
After the engine is started and preheating, the injection computer should stop the pre/
postheating unit operating.
Status ET007 Should change to NO.
In the event that the vehicle does not start and status ET007 remains at NO, check the
continuity and the absence of interference resistance of the following connections:
Injection computer grey 32-track connector C, track A4 Track 9 preheating
unit
Injection computer grey 32-track connector C, track E2 Track 8 preheating
unit
Repair if necessary.
If the fault is still present, refer to the interpretation of faults:
DF017 Preheating relay control circuit.
DF025 Pre-postheating unit diagnostic connection.
AFTER REPAIRCarry out a road test followed by another check with the diagnostic tool.

In the event that the low-speed engine fan does not work, refer to the UPC fault finding note.
STOPPED
The low-speed fan assembly stops when:
– the engine coolant temperature is below 89°C,
– no air conditioning request made by the driver.
IMPORTANT!WARNING
If the UPC does not detect the injection computer frames, the low-speed engine
fan assembly is supplied until the battery is completely discharged.
In the event that the low-speed engine fan assembly is defective, the high-speed
engine fan assembly will then be activated.

ET042
CRUISE CONTROL/SPEED LIMITER
STATUS DEFINITION
NOT DETECTED: This status indicates that the cruise control or speed limiter function
is not present on the vehicle.
INACTIVE: This status indicates that the cruise control/speed limiter main On/Off
switch is in the rest (or neutral) position.
SPEED LIMITER: This status indicates that the driver has used the main switch to
select the speed limiter.
CRUISE CONTROL: This status indicates that the driver has used the main switch to
select the cruise control.
NOTESSpecial notes:
Only perform these tests if the statuses do not correspond with the system
programming functions.
NOT
DETECTED
If the vehicle does not have cruise control or 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, 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
The tool displays status ET042 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 status ET042.
If ET042 is INACTIVE, the injection computer has detected the various positions of the
main switch. The cruise control/speed limiter is activated.
2 If ET042 is NOT DETECTED, check that the owner of the vehicle has not, sometime
in the past, asked for the cruise control/speed limiter function to be deactivated.
Contact the Techline.
AFTER REPAIRDeal with any faults.
Carry out a road test followed by another check with the diagnostic tool.

(CONTINUED 1)
INACTIVE
When the main switch is in rest position (or neutral), status ET042 is INACTIVE.
If CRUISE CONTROL or SPEED LIMITER appears despite the main button being in the
rest position (or neutral), carry out the following operations:
Check the connections of the cruise control/speed limiter main switch.
Check for + 12 V APC on the main switch connector.
– Connection code AP43 of component 1081 (Mégane II)
– Connection code AP43 of component 1546 (Scénic II)
Disconnect the main switch and with it in the rest position, check the insulation between:
– Connection codes AP43 and 3FX of component 1081 (Mégane II)
– Connection codes AP43 and 3PD of component 1081 (Mégane II)
– Connection codes AP43 and 3FX of component 1546 (Scénic II)
– Connection codes AP43 and 3PD of component 1546 (Scénic II)
Check the continuity between connections AP43 and 3PD of component 1081
(Mégane II) and component 1546 (Scénic II) in the speed limiter position.
Check the continuity between connections AP43 and 3FX of component 1081
(Mégane II) and component 1546 (Scénic II) in the cruise control position.
If these checks are not in order, replace the switch.
Check the insulation, continuity and the absence of interference resistance on the
following connections:
– Connection code 3FX,
– Connection code3PD.
Between components 1081 and 120 (Mégane II)
Between components 1546 and 120 (Scénic II)
Also check the engine management computer connectors.
If there is a repair method (see Technical Note 6015A, Repairing electrical wiring,
Wiring: Precautions for repair), repair the wiring, otherwise replace it.
AFTER REPAIRDeal with any faults.
Carry out a road test followed by another check with the diagnostic tool.
