GENERAL INFORMATION
JUMP-STARTING, VEHICLE EQUIPPED
WITH THEFT SECURITY SYSTEM . After the
booster battery has been connected, the Theft System
must be turned OFF. Using the key, lock then un-
lock either front door. This turns the Theft System
OFF and the remainder of the Jump-Starting proce-
dure can be followed. If this procedure is not followed, the Theft System
electronics will prevent the engine from starting. If a new Powertrain Control Module is installed,
the engine has to be cranked 20 times before the
alarm system activated. This passive system is designed to protect against
whole vehicle theft. The system monitors vehicle
doors, hood, trunk key cylinder, and ignition action
for unauthorized operation. The alarm activates by
sounding the horn, flashing the park and tail lamps,
and providing an engine kill feature (Fig. 1). Passive arming occurs upon normal vehicle exit,
open door, lock with power locks, close door. The SET
lamp in the panel will flash for 15 seconds, indicat-
ing that arming is in progress. If no monitored sys-
tems are activated during this period, the system
will arm. If the hood or trunk key cylinder switches
are not sensed by the system. The SET lamp will re-
main lit during the arming process, although the sys-
tem will still arm. The system is to be considered as
an active armed system when using the Remote Key-
less Entry. If the SET lamp does not illuminate at all
upon door closing it indicates that the system is not
arming. Passive disarming occurs upon normal vehicle en-
try unlocking either door with the key, or unlocking
using the Remote Keyless transmitter. This disarm-
ing will also halt the alarm once it has been acti-
vated. Whenever the battery is disconnected and recon-
nected, the Vehicle Theft Security System enters
power up alarm mode which flashes the park and tail
lamps and prevents the engine from running. To exit
this mode, the system must be disarmed as men-
tioned above. A tamper alert exists to notify the driver that the
alarm had been activated, and the alarm has since
timed-out for more than 18 minutes. This alert con-
sists of 3 horn pulses when the vehicle is disarmed. The alarm system will not arm if the doors are
manually locked, providing a manual override of the
alarm.
WHAT WILL TRIGGER THE SYSTEM
One of the following actions will trigger the system
while it is armed. Without properly disarming sys-
tem, by using the key or the remote transmitter. (1) Opening the HOOD.
(2) Opening any DOOR.
(3) Removing the TRUNK KEY CYLINDER.
(4) Turning the IGNITION ON.
(5) The ignition switch can be turned to the acces-
sory position without triggering alarm system.
SYSTEM SELF-TESTS
A diagnostics mode is available in the system to
verify operation of all monitored switches or circuits.
To enter diagnostics, cycle the ignition key to the ac-
cessory position 3 times, leaving the key in this po-
sition. Upon entering diagnostics, the park and tail lamps
will begin flashing to verify their operation. In addi-
tion, the horn will sound twice to indicate that the
trunk key cylinder is in its proper position. Return-
ing the ignition to the OFF position will stop the
lamps from flashing while keeping the system in di-
agnostics. While in diagnostics mode, a horn pulse should oc-
cur at each of the following events indicating proper
operation: (1) Beginning with all doors closed, open then close
each door. The horn will sound when the door ajar
switch closes, and then again when the switch opens.
There must b e a 1 second delay between closing and
opening the switch. (2) Open, then close the hood. The horn will sound
when the hood is opened, and again when it is closed.
