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-
