Volumetric Sensor - If Equipped

The volumetric sensor is located in a central position in the front overhead console. The volumetric sensor comprises 3 sensors which allow the passenger compartment of the vehicle to be monitored. The Body Control Module/Gateway Module (BCM/GWM) provides a permanent power supply for the volumetric sensor. The volumetric sensor signals are transmitted to the BCM/GWM on a Local Interconnect Network (LIN) bus connection.

Double Locking Vehicles 

The volumetric sensors are activated when the vehicle is double locked. The vehicle can be locked and alarmed with the volumetric sensors deactivated. This can be achieved by single locking the anti-theft active system or by deactivating the alarm sensors in the Instrument Cluster (IC) settings menu.

In certain markets (Benelux) the volumetric sensors (if equipped) are activated on single locking as a market requirement.

When volumetric sensors are active and the startup battery voltage falls below 9V, the Body Control Module/Gateway Module (BCM/GWM) ignores any inputs to prevent false alarm activation.

The BCM/GWM ignores the signals from the volumetric sensor for the first 15 - 30 seconds to allow time for the passenger compartment to settle and prevent false alarm activation.

If the tailgate is opened via the smart key, the volumetric sensor and the tilt sensor are inhibited until the tailgate is closed.
