ALP27 Locking/unlocking fault when pressing card button.
NOTESCheck that there is no APC or card in the card reader.
Check that no opening element is detected as open by the UCH (look at the symbol on
the instrument panel).
First carry out a function fault finding check.
Test with the other card.
Check the condition of the battery (inserted the wrong way round, flat, incorrect
model).
If the fault is still present after having carried out a test with the other card, it could be that:
–There may be radiofrequency interference in the area (ET066 Card button press received is NO for both
cards). Move the vehicle to try again.
–The UCH which has just been replaced does not have the correct part number (external or internal UCH
aerial). Use the correct UCH part number.
–If the vehicle is a Scenic II fitted with a tyre pressure monitoring system, check that the external UCH aerial
is connected correctly.
–Check that the UCH for the vehicle is not blank. Check that the UCH on the vehicle has not been used on
another vehicle.
Check that statuses ET066 Card button press received and ET067 Card button press recognised are YES
after pressing the card's lock or unlock button.
If not, apply the fault finding procedures for those statuses.
Check that statuses ET066 Card button press received and ET067 Card button press recognised are YES
after pressing the card's lock or unlock button.
If not, apply the fault finding procedures for those statuses.
Check that status ET014 Control power level is not APC.
If not, apply the fault finding procedures for this status.
Check that statuses ET041 Opening rear screen, ET042 Passenger's door, ET050 Tailgate/Boot, ET051 Rear
