Anti-Theft - Active (G1818046): Operation: Alarm

WARNING: This page is about a different car, the 2020 Jaguar XE and 2019 Jaguar XE. However, it is still accessible from the selected car via links, so may be relevant.

When the alarm is triggered, the BCM/GWM activates audible and visual warnings. The audible warnings are produced by the security sounders - Passive sounder or the BBUS and vehicle horns (market dependent). Visible indications are produced using the turn signal indicators.

The BCM/GWM activates the security sounders - Passive sounder or the BBUS and vehicle horns (market dependent) and the visual indications for 30/60 seconds, depending on the market. The activation is stopped for 10 seconds and, if the alarm trigger is still present, the BCM/GWM will cycle again for 30/60 seconds. This will be repeated for up to a maximum of 10 cycles per trigger source (3 cycles in certain markets) of 30/60 seconds for any one arming period. The BCM/GWM will ignore the trigger cause if the 10 cycles (3 cycles in certain markets) have been completed and the alarm trigger is still present or until it receives a disarm signal.

NOTE: If the BBUS (Battery Back Up Sounder) is triggered due to tamper detection, the visual indication using the turn signal indicators is not activated.

The alarm can be triggered by any of the hinged panels being opened or doors unlocked, the volumetric sensor detects a movement inside the vehicle, the tilt sensor detects vehicle movement or an ignition tamper is detected (invalid smart key).
