2427986 - E3040 CENTRAL LOCKING - Description (Low setup)

Description

The door locks are operated simultaneously by:

• the key;
• the door handles;
• driver door buttonns
• the 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;In general, the door/boot lock/release strategy is governed by the Body Computer while the door and boot control units (located in the driver's door) 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 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;
• 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.
