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.
