DWA: Anti-theft alarm system
For the DWA control unit, the FZD control unit is the interface to the K-CAN.
The DWA control unit receives messages about the doors and engine hood as well as the boot lid (e.g. closed,
open) via the K-CAN.
The DWA control unit evaluates the signals from the ultrasonic interior motion sensor.
The messages from the DWA are looped through the roof control panel. This means that the cables for the
anti-theft alarm system are routed through the roof control panel housing.
Messages from the DWA control unit are fed via a direct wire to the DWA LED. The DWA control unit is
connected to the siren with tilt alarm sensor via the K-bus.
