Alarm System
The alarm system detects and warns of any attempts to break in or tamper with the vehicle. The system is installed in various types of vehicles in different country specific versions.
The antitheft alarm system, integrated in the CAN-Sine, communicates with the components via the KCAN or via the DWA bus. The DWA of the E63 is equipped with multiplex microwave sensors, the Can-Sine and the DWA LED.
For the first time at BMW, MuW (multiplex microwave sensors) sensors are fitted in the E63.





The advantages of these MuW sensors are:
^ Interior protection
^ Effective MuW sensor detection during interior monitoring
^ No false alarms triggered by MuW sensors during interior monitoring
The processor in the Can-Sine features diagnostic capabilities and can be encoded. The MuW sensors assume the secondary functions and the CAN-Sine the main control unit function.
The E63 is not equipped with the Ultrasonic interior movement detector USIS. The DWA logic and the emergency current siren with integrated tilt alarm sensor have been combined to form one unit, i.e. the CAN-Sine.
