GENERAL INFORMATION
cycle the ignition switch. To transfer back to dealer
storage mode, the DRBIII must be used, the IOD
fuse removed, and the ignition switch cycled. Some-
times the instrument cluster doesn't transmit a
message upon change of the IOD fuse. By cycling
the ignition, this causes the cluster to transmit the
message, thereby ensuring the RKE module has
received the most recent IOD status.
3.6.1 VEHICLE THEFT SECURITY SYSTEM
The VTSS monitors the vehicle doors, decklid,
hood and the interior of the vehicle (via the intru-
sion sensor) for unauthorized operation. The alarm
activates by sounding the siren, flashing the turn
indicators and the VTSS indicator in the instru-
ment cluster. Locking the doors with the door lock
switch (through following a normal exit sequence of
opening the door, pressing the lock button, and
closing the door), the door cylinder lock switches or
the RKE transmitter arms the system. During the
16 second arming process the VTSS indicator will
flash quickly and when the system is armed will
slow down. The system will not arm if the hood is
open (switch is grounded). Once the system is
armed, the door cylinder unlock switches may not
be used to disarm the alarm system. The only way
to disarm the system is to use the RKE transmitter
or turn the ignition on with a valid Sentry key.
All of the sensors for the VTSS system can be
monitored using the DRBIII . The DRBIII is also
useful to determine the cause of a customer com-
plaint of the alarm going off with no apparent
reason.
3.6.2 POWER DOOR LOCKS
3.6.2.1 CENTRAL LOCKING
This feature allows the customer to lock/unlock
all vehicle doors with the key from either front door
cylinder lock switch. The customer can choose to
program this feature to unlock all doors with one
turn of the key or open the driver door only with the
first turn of the key and open the other doors with
the second turn. Altering the operation of the un-
lock function via the key cylinder switch from one
turn to two turns will also alter the operation of the
RKE transmitter from one press to two presses.
3.6.2.2 ROLLING (AUTOMATIC) DOOR
LOCKS
All vehicle doors are locked automatically once
the vehicle reaches a speed of 15 mph and all doors
are closed. This feature can be also be enabled/
disabled by the customer.
3.6.2.3 DOOR LOCK INHIBIT
This feature disables the door lock command from
the interior door lock switch whenever the dirver
door is open and the key is in the ignition. This
prevents the driver from locking the keys in the
ignition when using the power door locks. This
feature is inoperable if the IOD fuse is not installed.
3.6.2.4 POWER DECKLID RELEASE
Electrically releases the decklid upon two presses
of the RKE transmitter decklid release button. This
feature is disabled once the speed of the vehicle is
greater than 5 mph. This feature may be altered
with the DBRIII to allow the decklid to be released
with one press of the RKE transmitter decklid
release button. The decklid can also be released
from the switch in the glove box.
3.6.2.5 PANIC MODE (IF EQUIPPED)
Upon activation of the panic function, the head-
lamps and park lamps flash in an alternating
manner, the horn pulses every second and the
courtesy lamps are turned on. The panic mode
allows normal nightime driving by allowing the
headlamps and park lamps to be on steady when
the headlamp switch is in the on position. Panic
mode is activated immediately by pressing the
panic button once. It does not disarm the VTSS or
unlock the doors. It is canceled by pressing the
button a second time, reaching vehicle speed
greater than 15 mph or after 3 minutes has elapsed
in panic mode. Once panic mode has been activated
there is a 2-second delay before it will turn off. Once
it is cancelled there is a 2-second delay before it can
be reactivated. This is to avoid the problem of
deactivating and immediate reactivating due to
multiple button presses.
3.7 VEHICLE COMMUNICATION
The Programmable Communication Interface or
PCI Bus is a single wire multiplexed network capa-
ble of supporting binary encoded messages shared
between multiple modules. The PCI bus circuit is
identified as D25 and is violet with a yellow tracer.
The modules are wired in parallel. Connections are
made in the harness using splices. The following
modules are used on 2001 PL:
•
Airbag Control Module
•
Left Side Impact Airbag Control Module
•
Right Side Impact Airbag Control Module
•
Controller Antilock Brake
•
Power Control Module
•
Radio
•
CD Changer
