Trunk lid switch

The status of the trunk lid switch is analysed by the Junction Box electronics and signalled to the ultrasonic interior movement detector. When the trunk lid is closed, the Junction Box electronics receives a low signal (approximately 0 V). If the trunk lid is unlocked when the anti-theft system is activated, the signals from the trunk lid switch, ultrasonic interior movement detector and tilt sensor are initially suppressed.

The signals are also suppressed if the trunk lid is unlocked using the ID transmitter when the anti-theft system is activated. The trunk lid switch is reinstated as part of the vehicle monitoring system 6 seconds after the lid is closed. Once there are no other doors open and the trunk lid is closed, the initialization procedure for the ultrasonic interior movement detector and the tilt sensor starts.

Because of the manipulation prevention system, unlocking the luggage compartment with the aid of the mechanical key when the DWA is activated will cause an alarm to be triggered.
