2427982 - E3040 CENTRAL LOCKING - Description (High setup)
Description
The door locks are operated simultaneously
by:
- the key;
- the door handles;
- driver door buttonns
- remote control.
The remote control key has 3 buttons which
make it possible to operate the central locking system: one button
for unlocking the doors, one for locking the vehicle and one for releasing
the boot;The locks are equiped with an additional
motor that performs the dead lock function.The DEAD-LOCK function makes it possible
to mechanically disconnect the door interior opening handles and
the safety knob so that the door cannot be opened from the inside (e.g.
after the glass has been broken in a theft attempt). It is impossible
to get out of the passenger compartment once the dead-lock function
has been applied.The Dead Lock function is engaged by turning
the mechanical key a second time within 1 second of locking the
doors or via remote control at the time the door is locked. In the latter
case, the lock key is pressed within 1 second of the first press.In general, the door/boot lock/release strategy
is governed by the Body Computer while the door and boot control
units control the lock motors in accordance with commands transmitted
by the Body Computer.Lock operation is managed by the Body Computer,which
monitors lock status via signals from switches on the locks (the
same signals are used for light timing). The lock command is therefore
executed only with all the doors properly closed and the locks released. conversely,
the 'release' command is only issued when the locks are locked;The Body Computer also manages dead-lock
function deactivation (the release operation requires preliminary
dead-lock deactivation)The two door lock/release button are located
on the driver door control unit and work in the same way as the
controls sent via key.The LED to the side of the driver's
door safety catch issues the following signals:
- Catches locked: the LED lights up for 3 seconds. If, when
the locks are locked some of the doors or the boot is not properly
shut, then the LED will flash at 3 Hz for 3 seconds;
- Dead-lock engagement: after the dead-lock has been engaged,
the LED will flash twice for 0.5 seconds and then swith to the deterrent
signal (with alarm function present).
- Unlocking the locks: the LED goes out
The instrument panel downloads a door status
signal from the CAN network and turns on the door open warning light
If one of the doors or the boot or bonnet lid is open and the speed
is above 4 Km/h then an acoustic signal is emitted.A special instrument panel feature can be
used to decide whether to release all doors or only the driver side
front door while all other doors and the boot remain locked.A special instrument panel feature can be
used to enable/disable the door lock beyond a set speed threshold
(20 km/h). In this case the Body Computer activates the door lock beyond
the set threshold.If the doors are locked by this function,
the user can still release the doors and they will not be locked
even if the speed exceeds 20 km/h.Similarly, the doors will not be released
if speed drops below 20 km/h with the doors locked.It is possible to select the boot
release operating mode using the special setup:
- boot release controlled by central locking: the status
of the boot follows the status of the door locks;.
- independent boot release: the boot is locked when the
doors are locked, whilst it is possible to unlock it independently
of the unlocking of the doors. See E3045 BOOT AND FUEL FLAP OPENING.
The doors are automatically released if
the inertia switch is activated: the instrument panel receives a
signal from the switch, lights up the relevant warning light and
communicates the activation to the Body Computer via the CAN network.The door lock circuit is protected by a
special fuse located in the unit under the dashboard.The remote control receiver aerial is connected
directly to the Body Computer which contains the electronics for
the actual receiver.
