Principles Of Operation: Arming

WARNING: This page is about a different car, the 2011 Jaguar XKR, 2011 Jaguar XK, 2010 Jaguar XKR, and 2010 Jaguar XK. However, it is still accessible from the selected car via links, so may be relevant.

On vehicles without intrusion detection modules and a tilt sensor, the active anti-theft system is armed in the perimeter mode when the vehicle is either locked or double locked.

On vehicles fitted with intrusion detection modules, the system has two modes of operation; perimeter mode and volumetric mode.

Perimeter Mode

Perimeter mode only monitors the hinged panels and validity of the remote handset/smart key in the start control module. Perimeter mode is activated by a single press of the lock button on either the smart key or the door handle lock button on vehicles with the passive entry system.

Volumetric Mode

Volumetric mode monitors the vehicle interior for intrusion. If the vehicle is fitted with a battery backed sounder which incorporates a tilt sensor, the vehicle attitude is also monitored when volumetric mode is active. Volumetric mode is activated by a second press of the lock button on either the Smart Key or the door handle lock button on vehicles with the passive entry system. The second press of either lock button must occur within 3 seconds of the first press. The second press of the lock button also activates the perimeter mode double locking feature.

The central junction box (CJB) arms the active anti-theft system when it locks or double locks the vehicle providing the following conditions are met:

All doors, liftgate and hood are closed
The smart key is not sensed inside the vehicle
The central junction box (CJB) is not in transit mode.

When the vehicle has successfully completed its locking routine, confirmation will be given by a long single flash of the turn signal indicators to indicate the locked condition. If double locking is activated then confirmation will be given by a double flash of the turn signal indicators, one flash for locked and one long flash for double locked. In certain markets an audible warning is emitted to confirm arming or double locking.
