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.
