Statuses available for the locking function:
System operation may be viewed using statuses ET045 RF frame received, ET066 Card button press received
and ET067 Card button press recognised.
The statuses of the doors detected by the UCH as open or closed are displayed using statuses ET053 Driver's door,
ET042 Passenger's door, ET051 Rear left-hand door, ET052 Rear right-hand door, ET050 Tailgate/boot and
ET041 Opening rear screen (if fitted to the vehicle).
The power supply level on the vehicle can be viewed using ET014 Power supply level requested.
d/ Boot-only locking/unlocking by pressing the "toggle boot status" button:
The boot alone may be locked/unlocked by pressing the "toggle boot status" button on the Renault card ("open
tailgate" symbol), if the card is less than 50 m from the vehicle (this distance varies according to the environment and
the battery power). The RF reception aerial is inside the UCH (except Scenic II fitted with the SSPP function).
Pressing the toggle boot status button on the Renault card starts the boot-only locking/unlocking procedure. When
the toggle boot status button is pressed, the card sends a 433 MHz encrypted signal to the UCH (315 MHz in Japan).
If the UCH authenticates the Renault card, it will authorise or inhibit opening of the boot depending on the previous
status (locked or unlocked).
Conditions required:
–The Renault card button must be pressed within the area covered by the card's radio frequency signal (this distance
varies according to the environment and the battery power).
–No + after ignition feed on the vehicle.
–No card in the card reader.
The statuses available for the boot-only unlocking/locking function (and for the opening rear screen if fitted)
are:
System operation may be viewed using statuses ET045 RF frame received, ET066 Card button press received
and ET067 Card button press recognised.
The open or closed status of the boot as seen by the UCH can be checked using status ET050 Tailgate/boot.
The status of the tailgate opening request is visible using status ET062 Tailgate opening request.
The open or closed status of the opening rear screen (if fitted) as seen by the UCH can be checked using status
ET041 Opening rear screen.
The status of the request to open the rear screen (if fitted) can be checked using status ET062 Rear screen opening
request.
The power supply level on the vehicle can be viewed using ET014 Power supply level requested.
e/ Principle of the identifier code:
The Renault card is authenticated by the UCH by transmission of a "rolling code" for the access function. The code
transmitted automatically increases incrementally each time the card is pressed.
To allow for the case where the signal is not received by the UCH, a table of 1024 accepted codes has been created.
The UCH and the Renault card can become desynchronised if the limit of 1024 possible presses is exceeded, that is
the customer has pressed more than 1024 times outside the reception zone.
If the Renault card does become desynchronised (code transmitted by the Renault card is outside the acceptance
limit of the UCH), the user can access his vehicle using the emergency insert. Resynchronisation is performed when
the vehicle is started with the card in the card-reader, or by removing/replacing the card battery.
