CENTRAL LOCKING - Description

Description

The door locks are operated simultaneously by:

• the key;
• the door handles;
• driver door buttonns
• remote control.
• Passive Entry function, if present

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 come with an auxiliary motor that is used for the Dead-lock function. The Dead Lock 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: once the Dead-Lock is activated, it is not possible to leave the passenger compartment). 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 remote control receiver aerial is connected directly to the Body Computer which contains the electronics for the actual receiver.

Passive entry

Description

The RF aerial-receiver sends the Passive Entry control unit a door opening/closing signal in the same way as a conventional remote control. for further details. See E7018 PASSIVE ENTRY

Description

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 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 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 before switching to a deterrent signal (with alarm function present). 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). *-Deterrence (with alarm function present).: once the signal that the doors are locked is over, the LED will flash at 0.8 Hz to indicate that the vehicle is locked (deterrent function). The deterrent function is also implemented if one or more of the doors or the boot is not properly closed. *-Catch release: the led goes off.

The door lock circuit is protected by a special fuse located in the unit under the dashboard.

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 re-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.

The fuel flap opening strategy is controlled directly by the driver door control unit because it is linked to driver door status.

Right hand drive

Description

The door locks are operated simultaneously by:

• the key;
• the door handles;
• driver door buttonns
• remote control.
• Passive Entry function, if present

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).

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.
