DESCRIPTION

The simultaneous operation of the front door locks takes place via:

- the remote control;

- the key inserted in the pawl on the driver's door;

- the locking/unlocking button in the controls in the centre of the dashboard.

The remote control unit has 3 buttons that allow control of the central locking system: a button for unlocking the doors, one for locking the vehicle and one for releasing the boot

    See descriptions 7005 PASSENGER COMPARTMENT FRONT SIDE DOORS

The door unlocking/locking management strategy is carried out by the Body Computer which controls the effective status of the locks by means of the signals that arrive from the switches in the actual locks: in this way, the locking command is only carried out if the doors are properly shut and the locks unlocked; conversely, the unlocking command is only carried out if the locks are locked.

The locks are equipped with an additional motor for the dead lock function which allows the mechanical unlocking of the interior door opening handles so that it is no longer possible to open the door from the inside (for example, after a window has been broken during a theft attempt)

The dead lock function is switched on at the time the doors are locked or by pressing the remote control twice.

An LED on the load compartment locking/unlocking button in the dashboard gives the following signals:

- locking of the locks: the LED lights up for 3 seconds. If some of the doors are not properly shut at the time when the locks are locked, the LED flashes at 3 Hz for 3 seconds;

- dead lock activation: the LED flashes twice for 0.5 seconds;

- unlocking the locks: the LED goes out.

The instrument panel acquires the door status signal via the CAN and lights up the doors open warning light and, at the same time, the information is shown on the display; in addition, if one of the doors is open and the speed of the vehicle exceeds around 4 km/h, an acoustic warning is also emitted.

A special setup in the instrument panel can be used to activate or exclude the Autoclose function, i.e. the automatic central locking whilst the vehicle is moving. This function allows the automatic locking of the doors to be activated when the speed exceeds 20 km/h.

The doors are automatically unlocked if the FPS is operated: the instrument panel receives an impact signal from the Air Bag control unit, lights up the warning light and notifies the Body Computer via the CAN.

All the door locking motors are protected by a dedicated fuse in the Body Computer.
