DESCRIPTION AND OPERATION VEHICLE ALARM SYSTEM BUILT-IN TEST
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 closed.
With assistance, 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 door
switch).
4.Turn starter switch 'off'.
5.Turn starter switch 'on'.
If the test mode has been correctly accessed, the
alarm sounder/horn will operate briefly and the
anti-theft alarm indicator and direction indicator lamps
will flash.
Perimetric tests
The anti-theft alarm indicator light and direction
indicator lamps will flash when:
1.Door switches are activated.
2.The bonnet is opened.
3.Key switches are activated.Volumetric tests
Press the LH (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
the anti-theft alarm indicator and direction indicator
lamps will illuminate.
NOTE: Exit the anti-theft alarm built-in test
by turning the starter switch to the 'off'
position.
If the previously described conditions are not achieved
during the built-in test procedure, this would indicate a
fault in the alarm system. Before undertaking detailed
fault diagnosis procedures, first make visual checks of
components such as a faulty door switch or blown
alarm system fuse.
