Antitheft Alarm System (DWA): Notes

The DWA electronics are integrated in the following control modules:

• Sedan, Coupe and Touring: Interior protection control module
• Convertible: Control module for siren with tilt sensor

The DWA electronics evaluate the signals relevant to the alarm system and decide whether the alarm should be triggered. The control module is connected to the data bus K-CAN SYSTEM, across which it receives the signals of the CAS, junction box electronics and footwell module control modules.

In the convertible, an additional separate DWA data bus is connected at the siren with tilt sensor control module. The signals between the DWA electronics and microwave sensors are transferred across this data bus.
