Door Locks: Security: Description: General
The security system is split into three elements: the locking system, the alarm system and the immobilization system. The locking and alarm systems are controlled by the Body Control Unit (BCU). The immobilization system is controlled by a dedicated ECU. The arming and disarming of the alarm system is linked to the activation of the locking system. The immobilization system operation is independent of both the locking and the alarm systems.
