Central Locking System: Notes

The central locking system ZV involves the actuation/evaluation of the doors, trunk and fuel filler flap. The central locking facilities of the doors are equipped with double lock functions and operate in accordance with the two-motor principle.

The door modules control the central locking facilities of the front doors. The basic body module controls the central locking in the rear area.

The central locking system consists of the following control points:

• Driver's door lock cylinder
• Center-lock button
• Remote control key
• Trunk lock cylinder

The system can be additionally unlocked via the crash sensor and forced release is possible by means of the "key inserted" signal in the CAS. A function is triggered when a status change at the respective input is detected. If several new ZV commands are given while a command is being carried out, only the last command will be subsequently executed. The CAS is the central locking master and is responsible for enabling all central locking procedures in the vehicle.

The central locking can assume following statuses:

Status	Explanation
Unlocked	All locks are in the unlocked position. Outer and inner door handles are operational.
Selective Unlocked	The driver's door is unlocked. All other locks are in the lock position.
Locked	All locks are in the lock position. Outer door handle not operational, inner door handle operational.
Secured	All locks are in the lock position. Outer and inner door handles are not operational.
