The anti-theft system on the F01/F02 is equipped with an ultrasonic interior
movement detector for monitoring
the vehicle interior. The ultrasonic interior movement detector USIS is fully
integrated in the FZD.
The anti-theft system is equipped with an ultrasonic interior movement detector.
The ultrasonic interior
movement detector has been fully integrated into the FZD.
The door switches (6, 7, 11, 12, Hall-effect sensors) are monitored by the
footwell module (13). As soon as the
status of a Hall-effect sensor changes, the ultrasonic interior movement
detector (14) receives that information
via the K-CAN2. If the anti-theft system is activated, an alarm is triggered.
The hood switch (1) is monitored by the Car Access System 4 (2). If the status
changes, an alarm is triggered in
the same way.
Opening of the trunk lid is monitored by the Junction Box electronics (4). If
the status of the trunk-lid switch
(10) changes, it triggers an alarm.
