Central Locking System Component Overview: Notes
Central locking functions electronically.
Actuators in doors are integrated in the door lock and have 2 motors.
Actuators cannot be replaced separately.
The first motor locks the door and the second motor locks the interior door mechanism (Safe function).

After an accident in which the airbag deploys, the central locking control module opens any doors which were locked.
