Electric door lock operation

ELECTRIC DOOR LOCK OPERATION

When the driver's door key (1) is turned or the sill button (2) is depressed to lock the drivers door, it mechanically locks the door latch (3) and triggers the latch switch (4) below the door lock. The latch switch makes an earth signal to the door locking control unit (5). When the control unit senses the earth signal, it operates the door lock motors (6) in the passenger doors thus locking them.

When the key is turned or the sill button is raised to unlock the driver's door mechanically, it again triggers the latch switch. The latch switch makes an earth signal to the door locking control unit. When the control unit senses this earth signal, it switches battery supply to operate the door lock motors (6) in the passenger doors thus unlocking them.

Note: There is no electric locking on the taildoor.
