The alarm system monitors the contacts on the doors, the tailgate and the engine compartment lid as well as the status of the tilt sensor and the interior monitoring.
The anti-theft alarm system consists of the ultrasonic interior movement detector (USIS) with ultrasonic interior sensors and the siren with tilt alarm sensor. The siren with tilt alarm sensor is connected via the LIN bus with the FZD control unit.
The ultrasonic interior movement detector is an ultrasonic interior sensor that detects movement in the vehicle interior and reports it to the FZD.
The software of the alarm system is integrated in the FZD control unit. This means the FZD control unit controls anti-theft alarm system.
