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.

ALP46 Steering lock fails
NOTESCheck for any faults on the steering lock.
Check the battery voltage. It should be between 9 V and 16 V.
Check the validity of parameter PR008 "Vehicle speed".
Check for any faults in the Airbag computer (impact detected) and ABS/ESP
computers.
Reminder: In hands-free mode, the steering column lock is locked as soon as the
ignition is switched off.
With the card in the reader, the steering column lock is locked after the ignition is
switched off as soon as the card is removed from the reader.
The conditions for a drop in + after ignition feed without the steering column locking are:
–the card is present in the card reader,
–over 20 minutes passing with the card in the card reader after the engine has stopped,
–the vehicle speed is not zero,
–power being requested by the steering column lock too frequently.
With regard to vehicles fitted with UCH computer Vdiag 4F or above:
–the Renault card is removed from the card reader when the vehicle is in forced + after ignition feed,
–3 mins have elapsed following a starting failure due to an engaged gear,
–the Renault card is removed from the card reader following a starting failure due to an engaged gear,
–a front door is open following a starting failure due to an engaged gear and the card is not in the reader.
Check that these conditions are not present.
Check the consistency of statuses ET072 Steering column lock and ET073 Steering column lock signal.
In the event of a fault, see the procedure for these statuses in the UCH section.
Check that the steering column lock belongs to the vehicle using status ET248 Steering column lock immobiliser
code.
If the fault is still present, contact the Techline.
AFTER REPAIRCarry out a complete check with the diagnostic tool.
