Anti-Theft - Active System Operation

The active anti-theft system is available with three different levels of vehicle protection depending on market specification:
Hinged panel sensing
Hinged panel and intrusion sensing
Hinged panel, intrusion and inclination sensing.
The system is controlled by software in the CJB and RJB and indicates a trigger condition: Visually, using the direction indicators, and
Audibly, using the vehicle horn and either a passive or active sounder to indicate a trigger condition.

The passive sounder takes the form of an anti-theft disc horn located at the rear of the engine compartment on the LH side. The active sounder takes the form of a battery backed sounder located in the same position.

Depending on market specification, the battery backed sounder may be fitted with an inclination sensor. Both types of battery
backed sounder are visually identical and can only be identified by their part number. Both are also intelligent units, and
communicate to the CJB over a LIN (local interconnect network) bus connection.

Monitoring of the hinged panels is carried out using switches located in each door latch assembly, the engine-compartment-lid
latch assembly, and the luggage-compartment-lid latch assembly. The condition of the switches is monitored by the CJB.

Monitoring of front door lock status is carried out using switches located in the door latch mechanisms. The condition of the
switches is monitored by the front door modules and transmitted to the CJB over the medium speed CAN (controller area
network) bus.

Monitoring of the cabin interior is carried out using an intrusion detection module mounted behind the roof console. The
intrusion detection module comprises an ultrasonic sound wave sensor to determine if there is movement within the cabin.
Information from the intrusion detection module is communicated to the CJB over a LIN bus connection.
CAUTIONS:

The intrusion detection module electrical connections, particularly those to the sensors mounted in the roof console, are
very delicate and must be handled with care.


The intrusion detection module is an electro-statically sensitive part and should only be handled in an electro-statically
controlled environment.
When armed, the active anti-theft system can be triggered in one of the following ways:
A door ajar switch indicates a door has been opened.
The engine compartment lid or luggage compartment lid ajar switches indicate that either has been opened.
Either front door latch mechanism indicates a door has been unlocked.
The emergency key blade is used to open either the LH front door or luggage compartment.
The CJB or RJB are disconnected (this may result in only a partial trigger).
An attempt is made to start the engine without a valid signal from the Smart Key.
Refer to: Anti-Theft - Passive (419-01B Anti-Theft - Passive, Description and Operation).

The battery backed sounder is disconnected (partial trigger only).
The vehicle battery is disconnected on a vehicle fitted with a battery backed sounder (partial trigger only).
The inclination sensor detects a change in vehicle attitude.
The intrusion detection module detects movement within the cabin.



Door Modules Component Description

The door modules provide the interface between the door latch-motors, the door latch-switches and the CJB. The door modules
provide door switch status information and enable the door latch-motors on request from the CJB or the keyless vehicle
module.

Keyless Vehicle Module

The keyless vehicle module interfaces with the Central locking, Radio Frequency (RF) receiver and collects RF signal information
which is transmitted from the Smart Key. This information is translated into commands which are passed on the medium speed
CAN bus to the:

CJB,
RJB,
door modules, and
instrument cluster.
The keyless vehicle module also monitors:
2 interior antennae,
1 luggage compartment antenna,
a rear bumper antenna, and
4 door handle antennae if the passive entry system is fitted.

On vehicles with passive entry, the additional fast latch motors are controlled via the keyless vehicle module and the locking
status is passed to the CJB on the medium speed CAN bus.

Instrument Cluster

The instrument cluster controls the alarm indicator, and in conjunction with the ECM (engine control module), the engine
immobilization. The ECM controls the engine crank and fuel functions and the instrument cluster processes the valid
transponder information.

Alarm Indicator

The alarm indicator is a LED (light emitting diode) located in the body of the sunload/light sensor. When the ignition is off the
indicator gives a visual indication of the active anti-theft system to show if the alarm system is active or not active. Operation
of the alarm indicator is controlled by the instrument cluster which varies the flash rate of the LED to indicate the system
status of the alarm and the immobilization systems.

When the ignition is on, the indicator provides a visual indication of the status of the passive anti-theft (engine
immobilization) system. If the immobilization system is operating correctly, the LED will be illuminated for 3 seconds at
ignition on and then extinguish. If a fault exists in the immobilization system, the LED will be either permanently illuminated
or flashing for 60 seconds. This indicates that a fault exists and fault code has been recorded. After the 60 second period the
LED will flash at different frequencies which indicate the nature of the fault.
Refer to: Anti-Theft - Passive (419-01B Anti-Theft - Passive, Description and Operation).
Passive Anti-Theft Horn

The passive anti-theft horn is hardwired to the CJB which activates the horn when the alarm is triggered.

Battery Backed Sounder

Operation of the battery backed sounder is controlled by the CJB on the LIN bus. The sounder is also connected with a
permanent battery supply via the CJB. An integral, rechargeable battery powers the sounder if the battery power supply from
the CJB is interrupted.

Dependant on vehicle, a incitation sensor is incorporated into the battery backed sounder, to monitor vehicle attitude, see
Inclination Sensor.

Inclination Sensor

The CJB monitors the inclination sensor and will activate the alarm system if the vehicle is being raised.

Intrusion Detection Module

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.
