an activation component. If after 3
seconds any input signal not in CLOSED
status is excluded (this is acknowledged
by the DWA LED) preventing false alarm
activation.
If the DWA is armed a second time
within 10 seconds, the tilt sensor and
interior protection sensor are also
excluded as alarm activation
components. This function is useful for
preventing false alarm activation if the
vehicle is transported on a train or flat
bed truck.
While armed the trunk can be opened
without the alarm being triggered as
follows:
If opened with the trunk remote
button via the FZV, the GM V
prevents the alarm from activating.
(This feature is customizable under
the Car Memory function.)
If opened with the key at the trunk
lock cylinder, the trunk key position
switch signals the GM V and in the
same manner prevents the alarm
from activating.
In either case, when the trunk is
returned to the CLOSED position, it
will no longer activate the alarm.
Alarm operation
When the alarm is triggered, the siren
will sound for 30 seconds. At the same
time the headlight low beams and
hazard lights will flash for 5 minutes.
The GM V signals the Light Center
Switch (LSZ) via the K-bus to flash the
lights. Following an alarm trigger, the
system will reset and trigger again if
further tampering is done to the vehicle.
