NOTESNo faults should be present or stored.
Check that configuration LC035 Child safety lock is WITH, if not perform configuration
using specific command SC016 Child safety lock (see Configurations and
programming). Status only visible if Vdiag 4C, 4D, 4F and 50 UCH.
Use Wiring Diagrams Technical Note for MEGANE II or SCENIC II.
IMPORTANT
After disconnecting the battery, there may be an inconsistency between a request on the switch and the status of
one or two lock(s).
In this case, deactivate and reactivate the switch until the warning light comes on when the switch is pressed.
Check the condition and connection of the lock connector (broken, bent, oxidised tabs).
If the connector is 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 the condition and connection of the PP2 connector of the UCH (tabs broken, bent, oxidised).
If the connector is 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 earth on connection MZ of component 139 or on connection MAQ of component 138.
If the connector is 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 the insulation, continuity and the absence of interference resistance on the following connections:
●Connection code 87A between components 645 and 139.
●Connection code 87B between components 645 and 138.
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 it.
Replace the faulty lock.
If the fault is still present, contact Techline.
AFTER REPAIRCarry out another fault finding check on the system.
Clear the stored faults.
Deal with any other faults.

Warning:
Use Workshop Repair Manual 364 (Mégane II) or 370 (Scénic II) or refer to the
pressure label attached to the driver's door to obtain the recommended pressures for
the tyres actually installed on the vehicle.
If, after comparing with the manufacturer's data (see MR 364 (Mégane II) or MR 370 (Scénic II), 35A), the
recommended pressures stored in the UCH do not conform, reprogram the recommended pressures using
command VP005 Enter recommended pressures (see Configurations and programming).
If the recommended pressures cannot be entered properly, contact Techline.

NOTESCheck the voltage of the battery.
Start the fault finding procedure with the ignition off and the vehicle locked.
When the vehicle is unlocked, the instrument panel should light up for a moment.
If not, carry out fault finding on the multiplex network and instrument panel.
Use Wiring Diagrams Technical Note for MEGANE II or SCENIC II.
The vehicle should switch to timed power (approximately 20 minutes) after the driver's door is opened (ET053
Driver's door).
If the timed supply is not triggered, try by:
–pressing the Start button (ET070 Start button), or
–turning on the hazard warning lights (ET085 "Hazard warning lights button"), or
–switching on the side lights (ET081 Lighting switch position).
If correct, run status fault finding for the faulty component.
If not correct, apply ALP No dialogue with the UCH.
The vehicle goes into accessories feed mode when the Start button is pressed (timed power active).
If it does not conform, check the operation of the Start button using status ET070 Start button and apply the fault
finding procedure associated with this status if necessary.
If the Start button operates correctly, use the fault finding procedure for status ET075 + accessories feed present.
Run fault finding and check the condition of the connectors of the + battery housing (Power fuses), of the power
board (maxi fuses), of the Protection and Switching Unit (UPC), of the Passenger Compartment Fuse and
Relay Box, of the Passenger Compartment Fuse and Relay Box option, and of the relay boards.
Check the condition and connection of the connectors on the UCH and the connectors on the UPC.
Check for + 12 V on connections BTP and 13AC of component 645.
Check for earth on connections 13E and NAM of component 645.
If one of the connectors is faulty and there is a repair procedure (see Technical Note 6015A, Electrical wiring
repair, Wiring: Precautions for repair), repair the connector, otherwise replace the wiring.
If the fault is still present, contact the Techline.
AFTER REPAIRCarry out a complete check with the diagnostic tool.

ALP41The vehicle does not start and the after ignition feed fails with the
card in the card reader
NOTESCheck the voltage of the battery.
First carry out a function fault finding check.
Switching to + accessories feed should work.
If not deal with ALP39 Accessories feed not activated first.
Check that the start-up conditions are met:
It can be checked while attempting to start if the immobiliser warning light:
–Remains on, meaning that the steering lock is not recognised.
–Remains on for 3 seconds and flashes at 4 Hz, meaning the card is not recognised.
It can also be checked while trying to start; if the Start button flashes, the card
has not been detected or recognised.
If the message "Insert card" is displayed on the instrument panel.
Insert the card in the card reader and run the special command SC005 Check card:
If the message "The inserted card cannot be detected or is not fully inserted into the card reader.
Check the card and the condition of the card reader. If the fault is still present, consult the fault finding for the
customer complaint in the fault finding manual (ALP41 for MEGANE II and ALP21 for CLIO III)" appears, try one
of the other vehicle's cards or a card from another MEGANE II vehicle.
–If the message appears again, apply the fault finding procedure for DEF014 Card reader circuit CC.0.
–If the message has disappeared and the result of the test is accessible, replace the defective card.
Check that status ET120 Card recognised by vehicle is definitely YES:
If ET120 Card recognised by vehicle is NO, the card does not belong to the vehicle or is damaged.
Check that status ET012 Card allocated to vehicle is definitely YES:
If ET012 Card allocated to vehicle is NO, the card is no longer allocated to the vehicle: re-allocate the vehicle's
cards using the special command SC006 Card allocation.
If the fault is still present, contact the Techline.
If the message "Insert card" is not displayed on the instrument panel.
Make sure statuses:
–ET008 Blank central unit is NO.
–ET071 Steering column lock blank is NO
See the procedure for these statuses if necessary.
Check that status ET110 UCH request to injection or UPC becomes START after a starting request is made
when the start conditions are met.
If everything is correct, run fault finding on the UPC.
If the fault is still present, contact the Techline.
AFTER REPAIRCarry out a complete check with the diagnostic tool.
