CENTRAL LOCKING - DESCRIPTION

Low setup, Right hand drive

DESCRIPTION

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

- TEG the remote control;

- the locking/unlocking button in the centre console.

The TEG remote has 3 buttons which 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 5520 ENGINE STARTING

The door unlocking/locking management strategy is carried out by the door control unit which controls the effective state of the locks through the signals arriving from the switches in the actual locks and the emergency key pawl (driver''s door only) in this way the "locking" command is only carried out with all the doors properly shut and the locks unlocked; conversely, the "unlocking" command is only carried out with the locks 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.

An LED next to the two above mentioned controls makes 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.

It is possible, using the special setup in the instrument panel, to select whether to unlock all the doors or only the driver''s front door, whilst all the other doors and the boot remain locked.

It is possible to enable/disable the locking of the doors above a certain speed threshold (20 km/h) using the special setup in the instrument panel: in this case the Body Computer implements the locking of the doors when this threshold is exceeded. When the speed returns below this level, the doors and the boot remain locked; later on, when one of the doors is opened, the function is re-enabled and, if the threshold is exceeded, the doors are locked once again.

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 E3045 BOOT AND FUEL FLAP OPENING - DESCRIPTION

The 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 central locking circuit is protected by a specific fuse located in the junction unit under the dashboard.
