199001295 - E3040 CENTRAL LOCKING - DESCRIPTION (5 door)

DESCRIPTION

The simultaneous operation of the four door locks takes place via:- the remote control;- the key inserted in the catch on the driver''s door;- the locking/unlocking button in the centre console.The remote control unit has 3 buttons that allow the operation 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

LOW specifications are equipped with a simple mechanical key with a fixed insert without a remote control.

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 and the key pawl (only drive''s door). in this way, the "locking" command is only carried out if all the doors are properly shut and the locks unlocked; conversely, the "unlocking" command is only carried out if the locks are locked;The locks have an additional motor that carries out the dead lock function which allows the interior door opening handles to be mechanically disconnected so that it is no longer possible to open the door from the inside (for example, after having broken the glass in a theft attempt); the dead lock function also inhibits the operation of the door locking/unlocking buttons in the dashboard.The dead lock function is switched on at the time the doors are locked or by pressing the remote control twice.A LED on the door lock/release key on the facia emits the following signals:- locking of the locks: the LED lights up for 3 seconds. If some of the doors or the boot 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 or the boot or the bonnet is open and the speed of the vehicle exceeds around 4 km/h, an acoustic warning is also emitted.The boot unlocking operating mode can be selected still using the special setup in the instrument panel:- assisted boot unlocking: the tailgate is considered as a fifth door to all intents and purposes;- independent boot unlocking: the boot is locked when the doors are locked, whilst it can be unlocked independently of the unlocking of the doors.    See E3046 BOOT OPENINGThe doors are automatically unlocked if the inertia switch is operated: the instrument panel receives a signal from the switch, lights up the appropriate warning light and notifies the Body Computer via the CAN.The door lock motors are protected by a special fuse on the Body Computer.
