Visual alarm via lighting system (hazard warning lights)
The alarm can be encoded according to the country concerned.
Brief description of components
The anti-theft alarm system receives input signals from the following components:
-
4 microwave sensors
The microwave sensors monitor the vehicle interior. Movement is detected if the reflection (echo) of the
microwaves changes. The sensitivity of the microwave sensors is adapted for different conditions (e.g. vehicle
model, installation location of microwave sensors).

-
Tilt alarm sensor
The tilt alarm sensor monitors the vehicle's horizontal position (inclination in longitudinal and lateral directions).
The signal from the tilt alarm sensor is evaluated by the DWA control unit. The tilt alarm sensor detects when the
vehicle is raised or towed away and triggers a DWA alarm.

The following control units are involved in the anti-theft alarm system:
-
DWA control unit
The software for the DWA is integrated in the emergency power siren. The DWA control unit in the emergency
power siren controls the anti-theft alarm.
The microwave sensors are connected to the alarm system control unit by a single-wire bus (K bus). The DWA
control unit is connected to the K-CAN.

-
Car Access System (CAS)
The CAS monitors the central locking system.
The bonnet contact switch is connected to the CAS. The bonnet is thus monitored (open or closed). The CAS
feeds the signal to the DWA control unit in the emergency power siren via the K-CAN. The CAS supplies the
following signals:
•
Boot-lid unlocking via remote control
•
Key in ignition starter switch or terminal 15 ON
•
Status of convenience opening/closing
•
Authentication by CAS as protection against manipulation
-
Driver's door module (TMFA) and front-passenger door module (TMBF)
The door modules provide information about the position of the door contacts. The signal is fed to the DWA
control unit in the emergency power siren via the K-CAN. The driver's door module also provides the signal from
the lock cylinder.
-
Body basic module (KBM)
The body basic module monitors the boot lid (open or closed). The signal is fed to the DWA control unit in the
emergency power siren via the K-CAN.
When the boot-lid lock is mechanically unlocked with the key, the DWA alarm is triggered.
-
Light module (LM)
The light module actuates the lighting system for the visual DWA alarm. The DWA control unit feeds the
triggering signal to the light module via the K-CAN.
The following actuators are actuated for the anti-theft alarm system:
-
Emergency power siren with integrated tilt alarm sensor (SINE)
SBT Anti-theft alarm system E63/E64
