Intrusion Detection Module

WARNING: This page does not describe the selected car, but rather 7 other vehicles, including the 2015 Jaguar XF, 2014 Jaguar XF, 2013 Jaguar XF, 2012 Jaguar XF, and 2011 Jaguar XF. However, it is still accessible from the selected car via links, so may be relevant.

The intrusion detection module comprises an ultrasonic sound wave sensor which monitors the vehicle's interior.

The intrusion detection module is activated with volumetric mode which in turn is enabled when the vehicle is double locked. The vehicle can be locked and alarmed with the module de-activated if a pet is to be left in the vehicle for example by single-locking the active anti-theft system. The intrusion detection modules can also be de-activated by deselecting the 'Alarm Sensors' option in the 'Vehicle Settings' screen on the Touch Screen Display.

NOTE: The Touch Screen method of de-activation of the intrusion detection module is only for one arm cycle, it will revert to active once the engine is next started.

When the volumetric mode is active and the vehicle battery voltage falls below 9 volts, the CJB will ignore any inputs from the intrusion detection module to prevent false alarm activation.
