ALP39 Accessories feed not activated
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.

ALP40 Forced after-ignition feed fails
NOTESCheck the voltage of the battery.
Carry out a fault finding procedure on the function.
Test with the other card.
Switching to + accessories feed should work.
If not deal with ALP39 Accessories feed not activated first.
It can be checked while trying to activate after ignition feed if the verlog indicator 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.
Review of the procedure for forcing after ignition feed:
+ accessories supply off, card in the card reader, starting conditions not met and after
pressing and holding the Start button (approximately 5 seconds).
Make sure that there is no Insert card message on the instrument panel.
Check that status ET008 Blank UCH is NO.
Refer to the procedure for this status if necessary (Blank UCH).
Check that status ET110 UCH request to UPC or injection becomes + after ignition feed after a request for
forced after ignition.
If everything is correct, run fault finding on the UPC.
Make sure the steering column lock functions properly by checking in particular that:
–statuses:
–ET071 Steering column lock blank is NO.
–ET072 Steering column lock is UNLOCKED.
–ET073 Steering column lock sensor signal is UNLOCKED.
See the procedure for these statuses if necessary.

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.

ALP42The vehicle does not start, the after ignition feed fails in hands-
free mode but works with the card in the card reader
NOTESFirst carry out a function fault finding check.
Test with the other card.
Switching to + accessories feed should work.
If not deal with ALP39 Accessories feed not activated first.
Check that the start-up conditions are met:
Check that the tailgate is detected as closed by the UCH using status ET050 Tailgate/
Boot.
Carry out the tests with the other cards allocated to the vehicle.
The card may be inhibited or the vehicle was not unlocked electrically: unlock by pressing the card button and
check if the hands-free starting fault is still present.
If the hands-free starting fault affects only one card:
Check that the card battery has been inserted the right way round. If the battery is flat or an incorrect model is being
used, replace the battery. If not, replace the faulty card.
If the hands-free starting fault affects every card:
Make sure the UCH is properly configured for hands-free operation. Reconfigure if necessary.
Make sure that the cards belong to the vehicle and are properly configured by running command SC005 Check
card.
If the cards belong to the vehicle but are incorrectly configured, program the cards.
Run command AC037 Transmitter aerial fault finding and see if a fault appears.
In the event of a present or stored fault, refer to the procedure for it.
If the vehicle is fitted with a tyre pressure monitor (Scénic II only), check that the external UCH aerial is correctly
connected.
Run command AC036 Interior aerial test and check the card coverage zone.
The card reader starts to flash as soon as a card is detected in the coverage zone.
The card should not be detected by the internal aerials when it is outside the vehicle.
If not correct, apply the relevant fault finding procedure for each command.
This mode allows of a Mégane hands-free type card to be detected as present, but not recognised.
Check the part number of the UCH and that it is hands-free.
If the fault is still present, contact the Techline.
AFTER REPAIRCarry out a complete check with the diagnostic tool.
