Principles Of Operation: Notes

The active anti-theft system arms and disarms in conjunction with the locking and unlocking of the central locking system. Refer to Handles, Locks, Latches and Entry Systems article.

Depending on the configuration of the central junction box (CJB), the active anti-theft system can be armed and disarmed when the locking system is activated with the Smart Key. Visual and audible confirmation of the arming and disarming is provided by the direction indicators and the BBUS.

On vehicles not fitted with the interior motion sensor and BBUS, the anti-theft alarm system is armed in the perimeter mode when the vehicle is either single or double locked.

On vehicles with the interior motion sensor the anti-theft alarm system is armed in one of two modes:

• Single Locking: only the hinged panels are monitored.
• Double Locking: the hinged panels the vehicle interior, and if the BBUS is incorporated the vehicle attitude, are monitored.

When the vehicle is double-locked, the central junction box (CJB) sends an arming signal to the BBUS and interior motion sensor. If the central junction box (CJB) does not receive an acknowledgment signal from the BBUS and the interior motion sensor, the central junction box (CJB) disables the associated alarm feature for the remainder of the armed cycle.
