Chrysler 2005 Sebring, Service Manual, Page: 587 / 3204

NOTE: The VTSS will not arm by pushing down the
door lock mechanism. This will manually override
the system.
For Door Cylinder Lock Switch Removal and
Installation, refer to Electrical, Power Locks, Door
Cylinder Lock Switch, Removal, and Installation.
If the VTSS is triggered, the horn will pulse, head-
lamps/marker lamps will flash, and the VTSS warn-
ing lamp will flash. If the BCM determines the
threat to be false and the VTSS is not triggered
again, the system will shut down and rearm itself
after three minutes. If a trigger is still active, the
alarm will continue for an additional 15 minutes
without the horn. The VTSS monitoring portion of
the system is split into two sections.
ARMING THE VTSS
(1) With the key removed from the ignition lock
and any door open (excluding decklid), actuate one of
the following:
•
Power door lock button to LOCK,
•
Key fob LOCK button
•
Door lock key cylinder to locked position.
(2) Close all opened doors. decklid can remain
open.
NOTE: If the decklid is open, it will not be secure.
Once the decklid is closed, a separate 16 second
counter will start. Once 16 seconds has been
reached, the decklid will then be secure, providing
a VTSS disarm request has not been received dur-
ing the 16 second decklid arming period.
(3) After the last door is closed, an arming time-
out period of sixteen seconds will start, then the
VTSS will become armed.
(4) If a 16 second time-out sequence was in process
and a new arm signal was actuated, the 16 second
time-out will restart from the time of the second
actuation.
If the LED indicator does not illuminate at all
upon final door closure, it indicates that the system
is not arming.
The current VTSS status armed or disarmed shall
be maintained in memory to prevent battery discon-
nects from disarming the system.
TRIGGERING THE VTSS
After the VTSS is armed, the following actions will
trigger the alarm:
•
Opening any door.
•
Turning the ignition to the ON, ACC, or
UNLOCK position.
•
Opening decklid without first receiving a RKE
input or decklid key input.
CAUTION: The VTSS indicator LED will trigger and
engine will continue to run if the vehicle is
equipped with SKIS and the proper key is used to
start the vehicle. This condition will occur if the
VTSS has been triggered. If valid key is used, VTSS
will disarm
SENTRY KEY IMMOBILIZER SYSTEM
The SKIS includes keys from the factory which are
pre-programmed. Each SKIM will recognize a maxi-
mum of eight Sentry Keys. If the customer would
like to own additional keys other than those provided
with the vehicle, they can be purchased from any
authorized dealer. These keys must be programmed
to the SKIM on the vehicle in order for the system to
recognize them as valid keys. This can be done by
the dealer with a DRB III
!
scan tool or by a cus-
tomer if this feature is available in their market and
they have two (2) valid keys already available to
them. Refer to the Service Procedures portion of this
system for additional details. The SKIS performs a
self-test each time the ignition switch is turned to
the ON position and will store Diagnostic Trouble
Codes (DTC’s) if a system malfunction is detected.
The SKIS can be diagnosed and any stored DTC’s
can be retrieved using a DRB III
!
scan tool as
described in the appropriate Body Diagnostic Proce-
dures manual.
