Signalling To Anti-Theft Alarm System (Via CAN)

The DWA is not part of the Central Locking system but it does require commands and signals from it. For this purpose, the DWA monitors the status of doors, hood, trunk and terminal status.

The DWA monitors the tilt sensor and the ultrasonic interior protection sensor by itself.

The DWA is armed by each valid locking (ZS) command. Optical feedback is provided by an LED, which signals the status of the DWA. The tilt and interior sensors are deactivated if a ZS command is initiated again within a specific period (10 s) after the first arming of the DWA.

The CAS forwards this information to the K-CAN P and K-CAN S. The DWA is disarmed by each double-unlocking command. The luggage compartment can also be accessed while the DWA is armed via remote control without the alarm being activated.

The alarm is activated if the trunk lid is opened mechanically using the emergency lock cylinder while the DWA is armed.

Scope of DWA monitoring from the Central Locking system:

• Door contacts
• Engine-hood contact
• Trunk-lid contact
• Tampering, driver's-door lock cylinder
