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.
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.

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.
