ALP33 Locking fault in hands-free mode
NOTESCheck that there is no APC or card in the card reader.
Conduct the tests with the other cards allocated to the vehicle.
First carry out a function fault finding check.
Make sure all the doors are fully closed (check that the interior lights are off or switch
on the ignition to check that no door is open from the instrument panel symbol).
Visually check that the lock buttons are not stuck in the down position.
Check that one of the cards has not been disabled (locked in the vehicle), activate the
+ after ignition feed with this card and attempt to unlock again with it.
If the fault only affects one card, replace the faulty card.
Make sure statuses ET058, ET059 and ET060 indicating a press on the lock button for each door or the boot
become active when the button is pressed.
Test all the lock buttons.
See the section for dealing with the status(es) concerned.
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 have a faulty configuration, 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.
Run the following commands and check the card coverage zone on each side of the vehicle:
AC032 Driver's side external aerial test
AC033 Passenger's side external aerial test
AC034 Boot external aerial test.
The card reader starts to flash as soon as a card is detected in the coverage zone.
The maximum distance from the vehicle is 1.5 m.
If not correct, apply the fault finding procedure associated with each command.
This mode enables a Mégane hands-free card to be detected in the coverage zone of the vehicle or that of
another vehicle.
Configure the UCH in hands-free function (see Configurations and programming).
If the fault is still present, contact Techline.
AFTER REPAIRCarry out a complete check using the diagnostic tool.
