AC AUTHORISED
NOTESSpecial notes:
Only perform these tests if the statuses do not correspond with the system
programming functions.
YES
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.
Status ET004 remains at 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 is activated correctly,
–the air conditioning system supply fuses,
–the presence of refrigerant in the air conditioning circuit,
–that the refrigerant fluid pressure value is consistent at idle speed.
If the fault is still present, check the climate control computer faults (see 62C, Air
conditioning).
AFTER REPAIRCarry out a road test followed by a complete test with the diagnostic tool.

PREHEATING UNIT CONTROL
NOTESSpecial notes:
Only perform these tests if the statuses do not correspond with the system
programming functions.
YES
When the vehicle is started from cold, the injection computer controls the pre-
postheating unit so that the vehicle can be started.
Status ET007 becomes YES a few seconds after the ignition is switched on and during
pre/postheating.
If the vehicle does not start and status ET007 becomes YES, check:
–the F2 (70A) supply fuse on the preheating unit, located on the power supply fuse
plate in the engine connection unit, below the Protection and Switching Unit,
–the resistance of the heater plugs.
Replace any plug whose resistance is not below 2 Ω.
If the vehicle starts and status ET007 remains YES during the engine operating phase,
refer to the interpretation of faults:
–DF017 Preheating relay control circuit.
–DF025 Preheating unit diagnostic connection.
After the engine is started and the preheating phase, the injection computer should stop
the pre-postheating unit operating.
Status ET007 should become NO.
In the event that the vehicle does not start and status ET007 remains NO, check the
continuity and absence of interference resistance of the following connections:
Injection computer Track A4 grey
32-track connector CTrack 9 preheating unit
Injection computer Track E2 grey
32-track connector CTrack 8 preheating unit
Repair if necessary.
If the fault is still present, refer to the interpretation of faults:
–DF017 Preheating relay control circuit.
–DF025 Preheating unit diagnostic connection.
AFTER REPAIRCarry out a road test followed by a complete test with the diagnostic tool.

CRUISE CONTROL/SPEED LIMITER
NOTESSpecial notes:
Only perform these tests if the statuses do not correspond with the system
programming functions.
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, the main switch
is in 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 page about testing the multiplex network with the CLIP program.
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 active.
2 - If status ET042 is still 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 REPAIRSwitch off the ignition and carry out a road test followed by a test with the diagnostic
tool.

CONTINUED 1
INACTIVEWhen 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 speed limiter position.
Check the continuity between connections AP43 and 3FX of component 1081
(Mégane II) and component 1546 (Scénic II) in 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 code 3PD.
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: Repair precautions), repair the wiring, otherwise replace it.
AFTER REPAIRSwitch off the ignition and carry out a road test followed by a test with the diagnostic
tool.
