3023310 - E3040 CENTRAL LOCKING - Description (3 porte, Guida a destra)

Description

The door locks are operated simultaneously by:

  • the key;
  • the door handles;
  • the button on the dashboard;
  • the remote control.

Lock operation is managed by the Body Computer, which controls:

  • the actual state of the locks by means of the signals which arrive from the switches located on the locks themselves (signals also used for timing the lights): in this way, the 'lock' command is only issued when all the doors are properly closed and the locks released; conversely, the 'release' command is only issued when the locks are locked;
  • the switch position. If this position does not agree with the action carried out (e.g. if after the lock command a door is open), a repulsion command is issued, i.e. the opposite manoeuvre is carried out to realign all the locks.
  • several consecutive and complete lock/release manoeuvres: if the control unit detects at least 10-11 manoeuvres within 25 seconds - the system cuts in to limit the manoeuvres: the system remains inhibited in the unlock position for 30 seconds
  • if the battery voltage falls below 8-10 V during a lock/release operation, the system suspends the operation. If battery voltage is lower than 8 V at the outset, no command is issued.
The signals coming from the door (and boot) open switches together - when the ignition is on - switch on the specific warning light on the instrument panel. The remote control receiver aerial is connected directly to the Body Computer which contains the electronics of the receiver proper: the remote control in the key has two separate buttons: one controls the door lock, the other the release (a third button controls the boot release  See E3046  BOOT OPENING ). If within 60 seconds from the lock release command issued via the remote control, the user has not shown his intention to take possession of the car (opening of doors and/or boot and ignition turned on), the locks are automatically LOCKED.The door lock/release button is located on the central panel: if the doors are closed, pressing the button releases them; vice versa if they are open, they are locked; an LED at the back of the button also comes on.The door lock circuit is protected by a special fuse located in the unit under the dashboard.
