DESCRIPTION AND OPERATION Mobilisation
The vehicle can be mobilised using any one of the
following processes:
1.Placing the handset in close proximity to the
starter switch with the starter switch turned on
(normally achieved by placing the key in the
starter switch, providing the key and handset are
attached).
NOTE: Under normal circumstances the
remobilisation of the vehicle will not be
apparent.
2.Pressing unlock button on handset.
3.Pressing lock button on handset with starter
switch turned on.
4.Entry of EKA code using the key.
NOTE: Any attempt to start the vehicle
using the key (detached from the handset)
will be unsuccessful. Use one of the above
methods.
See Warning indicators.
Volumetric protection
When the vehicle is locked using the handset both
perimetric and volumetric protection are activated
providing there is no mislock condition.
Perimetric protection
The vehicle is always perimetrically protected when
the alarm is armed using the handset. Perimetric
protection only, can be achieved if the vehicle is
locked using the key.
NOTE: The handset should ALWAYS be
used for unlocking the vehicle. If the
handset fails to unlock the vehicle
See
Repair, Handset.
Battery backed-up sounder (BBUS)
The sounder provides audible indication of alarm
status including:
Anti-theft warnings;
Confirmation of access to built-in test.
NOTE: Disconnecting the vehicle battery
will result in the alarm sounding if the
correct procedure has not been followed.
See Repair, Battery.
Alarm horn
The horn provides audible indication (as BBUS) of
alarm status.
NOTE: Disconnecting the vehicle battery
will have no effect on the horn.
Engine immobilisation warning light (EIWL)
NOTE: Under normal circumstances the
light will not illuminate.
The light will only illuminate (after 2 seconds) if the
handset is detached from the key (or the handset
fails) and an attempt is made to start the vehicle.
Anti-theft alarm indicator light
The light flashes to indicate the alarm status.
If the alarm system is fully armed, the light will flash
rapidly for 10 seconds and then settle to the slow
(anti-theft deterrent) flash.
If the alarm system is perimetrically armed, the light
will intermittently flash rapidly for 10 seconds and then
settle to the slow (anti-theft deterrent) flash.
If the alarm system is partially armed, the light will
NOT emit the slow flash until 10 seconds after arming
(to allow the cause to be investigated).
If the vehicle has been left unlocked, providing the
driver's door is closed, the light will flash slowly
indicating immobilisation. If the driver's door is open,
the light will remain illuminated.
Emergency key access (EKA)
The emergency key access code should be entered in
accordance with the instructions in the Owner's
Handbook.

DESCRIPTION AND OPERATION ANTI-THEFT ALARM BUILT-IN TEST (96 MODELS)
NOTE: The handset should be detached
from the key to allow perimetric testing of
the alarm system. The system will
automatically switch to volumetric testing if the
handset is in close proximity to the starter switch.
The built-in test procedure can be accessed providing
the following conditions exist:
Alarm disarmed.
Ignition off.
Doors unlocked.
Bonnet[hood] closed.
The test mode can be entered by completing the
following instructions within 5 seconds:
1.Open bonnet.
2.Turn starter switch on.
3.Open driver's door (far enough to activate
switch).
4.Turn starter switch off.
5.Turn starter switch on.
If the test mode has been correctly accessed, the
sounder/horn will operate briefly and the anti-theft
alarm indicator and hazard warning lights will flash.
Perimetric tests
The anti-theft alarm indicator light and the hazard
warning lights will flash when:
1.Door switches are activated;
2.The bonnet is opened;
3.Sill switches are activated;
4.Key switches are activated.
NOTE: Operation of key switches can be
verified by turning the key in the relevent
direction so as not to simultaneously
activate the sill switch. If the key switch changes
state, the change should be detected but the sill
switch will not be activated.
Volumetric tests
Press the unlock button or move the handset close to
the starter switch to disable perimetric testing and
enable volumetric testing. If movement is detected
within the vehicle by the ultrasonic sensor it will be
indicated by flashing the anti-theft alarm indicator and
hazard warning lights.
NOTE: Exit anti-theft alarm built-in test by
turning starter switch to the off position.

REPAIR HANDSET INITIALISATION
NOTE: New handsets are supplied in pairs.
If a new handset is required, it will require
initialisation to the ECU using the
following procedure:
1.Starting conditions: ignition off, doors unlocked,
bonnet switch depressed.
2.Carry out instructions 3. to 9. within 8 seconds.
3.Switch ignition ON.
4.Switch ignition OFF.
5.Lock doors.
6.Unlock doors.
7.Release bonnet switch.
8.Switch ignition ON.
9.Switch ignition OFF.
If alarm is correctly accessed, horn will sound and
LED will light. It is now possible to programme two
handsets of correct frequency to vehicle alarm ECU.
This must be carried out within two minutes.
10.Press and hold down button on first handset until
dash LED flashes.
11.Repeat instruction 10. for second handset.
12.The LED will extinguish if both handsets have
been initialised correctly.CENTRAL DOOR LOCKING
Where electrically operated central door locking is
fitted, locking or unlocking the drivers door from
outside by key operation, or from the inside with the
sill knob automatically locks or unlocks the passenger
and rear doors.
Front and rear passenger doors can be independently
locked or unlocked from inside the vehicle by sill knob
operation but can be overidden by further operation of
the driver's door locking control.
On rear doors, where side facing fold down seats are
fitted, a child safety lock is provided which can be
mechanically pre-set to render the interior door
handles inoperative.
Failure of a door actuator will not affect the operation
of the remaining doors and the door with the
inoperative actuator can still be locked or unlocked
manually.
The actuator unit fitted to the driver's door is the
master actuator and is identified from the actuators
fitted to the passenger and rear doors by having a
white connecting link, whereas the passenger and
rear door actuators have grey coloured connecting
links.
NOTE: Actuator units are non-servicable, if
a fault should occur replace the unit with a
new one.
