Anti-Theft - Active: Overview
Anti-Theft - Active
Overview
The active anti-theft system is available with three different levels of vehicle protection depending on market specification:
- Hinged panel sensing
- Hinged panel and intrusion sensing
- Hinged panel, intrusion and inclination sensing.
The CJB (central junction box) automatically arms and disarms the active anti-theft system when it functions the central locking system. For additional information, refer to Handles, Locks, Latches and Entry Systems Locations
Depending on market specification two modes of protection are used: perimeter mode and volumetric mode.
Perimeter mode
Perimeter mode, monitors the security of the hinged panels, which include:
- all doors,
- luggage compartment lid, and
- engine compartment lid.
When perimeter mode is active, the CJB monitors the panel ajar switches in the latch mechanisms of the hinged panels.
Volumetric mode
In volumetric mode the CJB monitors the interior of the vehicle for movement using an ultrasonic sound wave sensor.
If the battery backed sounder incorporates an inclination sensor the vehicle will also be monitored for unauthorized tilting; for example towing or jacking.
