more information on the features, use and operation
of all of the power distribution system components.
POWER DISTRIBUTION CENTER (PDC)
All of the electrical current distributed throughout
this vehicle is directed through the standard equip-ment Power Distribution Center (PDC). The molded
plastic PDC housing is located in the left front corner
of the engine compartment, just behind the air
cleaner housing and left of the battery (Fig. 1). The
PDC housing has a molded plastic cover. The PDC
cover is easily removed for service access and has a
convenient fuse and relay layout label affixed to the
inside surface of the cover to ensure proper compo-
nent identification.
The PDC housing is secured to the left inner
fender well an indexing pin and one screw. All of the
PDC outputs are through the integral engine com-
partment wire harness.
All of the current from the generator cable connec-
tion goes to the battery through a 140 ampere fusible
link that is secured with a nut to the positive battery
cable terminal. The PDC houses up to ten six fuse
cartridges, which replace all in-line fusible links. The
PDC also houses up to twelve blade-type fuses, up to
three full International Standards Organization
(ISO) relays, and up to eight mini International
Standards Organization (ISO) relays. Internal con-
nection of all the PDC circuits is accomplished by an
intricate network of hard wiring and bus bars. Refer
toPower Distributionin the Component Index of
Group 8W - Wiring Diagrams for complete circuit

engine compartment wire harness. If the PDC is
faulty or damaged, the engine compartment wire har-
ness assembly must be replaced.
FUSE BLOCK
An electrical Fuse Block is located in the left end
of the instrument panel (Fig. 2). It serves to simplify
and centralize numerous electrical components, as
well as to distribute electrical current to many of the
accessory systems in the vehicle.
The Fuse Block is positioned on a mounting
bracket up and under the left instrument panel. It is
secured by two screws. The fuse block is concealed
behind the left instrument panel end cap. The left
end cap is a snap-fit access cover that conceals the
fuse block fuses. A fuse layout placard is on the back
of the end cap to ensure proper fuse identification.
The fuse block houses blade-type fuses and auto-
matic resetting circuit breakers (Fig. 3). Internal con-
nection of all the fuse block circuits is accomplished
by an intricate network of hard wiring and bus bars.
Refer toJunction Blockin the Component Index of
Group 8W - Wiring Diagrams for complete circuit
diagrams.
The fuses and circuit breakers are available for
service replacement. The fuse block unit cannot be
repaired and is only serviced as an assembly. If any

DESCRIPTION AND OPERATION
INTRODUCTION
All doors can be locked or unlocked electrically by
operating the switch on either front door panel.
When the door lock switch is activated the Remote
Keyless Entry Module provides power to the door
lock motors through relays internal to the module.
The Remote Keyless Entry (RKE) Module also con-
trols the Vehicle Theft Security System (VTSS).
All doors can be locked or unlocked mechanically
and independently with their respective locking
knobs. The front doors can also be unlocked by actu-
ation of the inside remote door handle.
The RKE Module has three modes of operation
including customer usage mode, dealer lot storage
mode, and shipping mode. The customer usage mode
provides full functionality of the module and is the
mode in which the RKE module should be operating
when used by the customer. Dealer lot storage mode
and shipping modes are reduced power modes meant
to extend vehicle battery life during shipping and
storage in the dealer lot. Dealer lot storage mode pro-
vides limited VTSS and power door lock functions,
but disables the Remote Keyless Entry (RKE) func-
tions. This mode is intended to be used when the
vehicle is on the dealer lot to provide VTSS coverageof the vehicle while minimizing battery drain. Ship-
ping mode disables all normal functions (i.e. power
door locks, RKE, and VTSS) of the module, and is
intended to be used when the vehicle is shipped from
the assembly plant.
NOTE: The dealer must remove the module from
ªShip Modeº and place the RKE Module into either
the ªDealer Lotº storage or ªCustomer Usageº
modes of operation after receiving the vehicle from
the assembly plant. Refer to Group 8Q-Vehicle
Theft/Security Systems, Switching Operating
Modes/Configuring a New Module under Service
Procedures.
CENTRAL LOCKING/UNLOCKING
The door locks can be locked or unlocked electri-
cally via the exterior door key cylinders to provide
the central locking/unlocking feature. The central
locking/unlocking feature incorporates a customer
programmable ``Double activation unlockº feature
which operates in the following manner: When
enabled, the first turn of the key cylinder to the
UNLOCK position (toward the front of the vehicle)
will mechanically unlock the door whose key cylinder
is being turned. A second turn of the key cylinder to
the UNLOCK position (within five seconds of the

DESCRIPTION AND OPERATION
INTRODUCTION
The system allows locking and unlocking of vehicle
door(s), deck lid release, and panic by remote control
using a hand held radio frequency transmitter (Fig.
1). The module must be in the customer usage mode
of operation for the remote keyless entry system to
function.
The receiver may receive signals from up to four
transmitters. Each transmitter has its own code, and
the code is programmed and stored into RKE module
memory. If a transmitter is replaced or additional
transmitters are added, the codes for all units have
to be reprogrammed into the RKE module memory. If
a receiver module is replaced, the transmitter codes
must be stored in the new receiver memory (by per-
forming the steps for programming transmitters).The RKE module is capable of retaining all transmit-
ter codes when power is removed from the module.
Operation of the Remote Keyless Entry system
works in a similar manner to the central locking/un-
locking feature. With the double activation unlock
feature enabled, the first press of the transmitter
UNLOCK button will electrically unlock the driver
door, and a second press of the UNLOCK button
(within five seconds of the first) will unlock all vehi-
cle doors. With the double activation feature dis-
abled, all vehicle doors will unlock upon the first
press of the transmitter UNLOCK button. The vehi-
cle is locked electrically by pressing the transmitter
LOCK button once, regardless of the state of the dou-
ble activation unlock feature. The vehicle is shipped
with the double activation unlock feature enabled.
The deck lid can be unlatched manually via the
key cylinder from outside the vehicle, or by depress-
ing the deck lid release button on the RKE transmit-
ter twice (within five seconds).
The RKE module has three modes of operation
including customer usage mode, dealer lot storage
mode, and shipping mode. The customer usage mode
provides full functionality of the module and is the
mode in which the RKE module should be operating
when used by the customer. Dealer lot storage mode
and shipping modes are reduced power modes meant
to extend vehicle battery life during shipping and
storage in the dealer lot. Dealer lot storage mode pro-
vides limited VTSS and power door lock functions,
but disables the Remote Keyless Entry (RKE) func-
tions. This mode is intended to be used when the
vehicle is on the dealer lot to provide VTSS coverage
of the vehicle while minimizing battery drain. Ship-
ping mode disables all normal functions (i.e. power
door locks, RKE, and VTSS) of the module, and is
intended to be used when the vehicle is shipped from
the assembly plant.

NOTE: The dealer must remove the module from
ªShip Modeº and place the RKE Module into either
the ªDealer Lotº storage or ªCustomer Usageº
modes of operation after receiving the vehicle from
the assembly plant. Refer to Group 8Q-Vehicle
Theft/Security Systems, Switching Operating
Modes/Configuring a New Module under Service
Procedures.
REMOTE KEYLESS ENTRY SYSTEM
The system allows locking and unlock of vehicle
door(s) and deck lid by remote control using a hand
held radio frequency (RF) transmitter. The vehicle
speed must be less than five miles per hour before
the deck lid can be unlatched with the transmitter.
The receiver may receive signals from four transmit-
ters. Each transmitter has its own code and the code
has been stored in memory. If the transmitter is
replaced or other transmitters are added, the code for
each unit must be learned.
REMOTE KEYLESS ENTRY TRANSMITTER
The transmitter has four buttons for operation
(Fig. 1). They are LOCK, UNLOCK, DECK LID
RELEASE, and PANIC.
²The UNLOCK button will unlock the driver door
and enable illuminated entry. Pushing and releasing
the button once will unlock the driver door. Pushing
and releasing the button two times within a five sec-
ond period will unlock all doors (double unlock acti-
vation enabled).
²Upon pressing the LOCK button, the horn will
sound a short chirp (if enabled) and flash the park
lamps to notify that the all door lock signal was
received and acted upon. Illuminated entry is can-
celled and the interior lamps are faded to off.
²Pushing and releasing the DECK LID
RELEASE button twice within a five second period
will actuate the decklid release solenoid, causing the
deck lid to be slightly ajar. If so desired, the decklid
may be set to release after one button push by the
dealer. For procedures on programming with the
DRB IIItscan tool, refer to the proper Body Diagnos-
tic Procedures Manual.
²Pushing the PANIC button will cause the panic
alarm to sound for three minutes, until the panic
button is pressed a second time, or until the vehicle
reaches a speed of 15 mph.
HORN CHIRP TOGGLE
Once the transmitters have been programmed, the
horn chirp can be enabled/disabled by sending the
horn chirp toggle operation code to the RKE Module.
This can be done using a DRB IIItscan tool or by
the customer. The horn chirp will enter the oppositestate of its current programmed state by receiving
this operation code. The RKE module is responsible
for keeping track of the horn chirp status.

DESCRIPTION AND OPERATION
INTRODUCTION
The Vehicle Theft/Security System (VTSS) is
designed to protect against whole vehicle theft. The
system monitors vehicle doors, hood, trunk key cylin-
der, and ignition for unauthorized operation.
The VTSS activates:
²Sounding of the horn.
²Flashing of the park lamps.
²Flashing of the headlamps.
The RKE Module has three modes of operation
including customer usage mode, dealer lot storage
mode, and shipping mode. The customer usage mode
provides full functionality of the module and is the
mode in which the RKE Module should be operating
when used by the customer. Dealer lot storage mode
and shipping mode are reduced power modes meant
to extend vehicle battery life during shipping and
storage in the dealer lot. Dealer lot storage mode pro-
vides limited VTSS and power door lock functions,
and disables the Remote Keyless Entry (RKE) func-
tions. This mode is intended to be used when the
vehicle is on the dealer lot to provide VTSS coverage
of the vehicle while minimizing battery drain. Ship-
ping mode disables all normal functions of the mod-
ule with the exception of communications over the
vehicle's PCI bus, and is intended to be used when
the vehicle is shipped from the assembly plant. The
dealer must remove the module from shipping modeand place it into either the dealer lot storage or cus-
tomer usage modes of operation.
NOTE: The dealer must remove the module from
ªShip Modeº and place the RKE Module into either
the ªDealer Lotº storage or ªCustomer Usageº
modes of operation after receiving the vehicle from
the assembly plant. Refer to Switching Operating
Modes/Configuring a New Module under Service
Procedures in this section.
VEHICLE THEFT/SECURITY SYSTEM (VTSS)
In the customer usage mode of operation, the sys-
tem is armed when the vehicle is locked using the:
²Power door lock switches.
²Remote Keyless Entry (RKE) transmitter.
After the vehicle is locked and the last door is
closed, the circular red VTSS indicator in the instru-
ment cluster will flash quickly for 16 seconds, indi-
cating that arming is in progress. If no monitored
systems are activated during this period (excluding
the hood and trunk key cylinder), the system will
arm. After 16 seconds, the LED will continue to flash
at a slower rate indicating the system is armed.
If the hood ajar switch and/or trunk key cylinder
switch(s) are not sensed by the system, the indicator
LED will remain lit during the arming process,
although the system will still arm. If the VTSS indi-
cator does not illuminate at all upon door closing it
indicates that the system is not arming.
PLVEHICLE THEFT/SECURITY SYSTEM 8Q - 1

VTSS disarming occurs upon normal vehicle entry
by unlocking either door via the key cylinders or
RKE transmitter, or by starting the vehicle with a
valid Sentry Key. This disarming will also halt the
alarm once it has been activated.
A tamper alert exists to notify the driver that the
system had been activated. This alert consists of 3
horn pulses when the vehicle is disarmed.
The VTSS will not arm by mechanically locking the
vehicle doors. This will manually override the sys-
tem.
In the dealer lot storage mode of operation, all of
the above descriptions of the VTSS are true with the
following exceptions:
²Remote Keyless Entry functions are disabled,
and cannot be used for arming/disarming the VTSS.
²The VTSS indicator is non-operational.
SENTRY KEY IMMOBILIZER SYSTEM (SKIS)
The Sentry Key Immobilizer System (SKIS) is
designed to provide passive protection against unau-
thorized vehicle use by preventing the engine from
operating while the system is armed. The primary
components of this system are the Sentry Key Immo-
bilizer Module (SKIM), the Sentry Key transponder,
the Vehicle Theft/Security System (VTSS) indicator
LED, and the Powertrain Control Module (PCM).
The SKIM is installed on the steering column near
the ignition lock cylinder. The transponder is located
under the molded rubber cap on the head of the igni-
tion key. The VTSS indicator LED is located in the
instrument cluster.
The SKIS includes three valid Sentry Key tran-
sponders from the factory, one being a valet key. This
is so the customer can self program new keys if one
is lost. If the customer wishes, additional non-coded
blank Sentry Keys are available. These blank keys
can be cut to match a valid ignition key, but the
engine will not start unless the key transponder is
also programmed to the vehicle. The SKIS will recog-
nize no more than eight valid Sentry Key transpon-
ders at any one time.
The SKIS performs a self-test each time the igni-
tion 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 can be retrieved using a DRB
llltscan tool as described in the proper Body Diag-
nostic Procedures Manual.
SENTRY KEY IMMOBILIZER MODULE (SKIM)
The Sentry Key Immobilizer Module (SKIM) (Fig.
1) contains a Radio Frequency (RF) transceiver and a
central processing unit, which includes the Sentry
Key Immobilizer System (SKIS) program logic. The
SKIS programming enables the SKIM to programand retain in memory the codes of at least two, but
no more than eight electronically coded Sentry Key
transponders. The SKIS programming also enables
the SKIM to communicate over the Programmable
Communication Interface (PCI) bus network with the
Powertrain Control Module (PCM), the instrument
cluster and/or the DRB IIItscan tool.
The SKIM transmits and receives RF signals
through a tuned antenna enclosed within a molded
plastic ring formation that is integral to the SKIM
housing. When the SKIM is properly installed on the
steering column, the antenna ring is oriented around
the circumference of the ignition lock cylinder hous-
ing (Fig. 1). This antenna ring must be located
within eight millimeters (0.31 inches) of the Sentry
Key in order to ensure proper RF communication
between the SKIM and the Sentry Key transponder.
For added system security, each SKIM is pro-
grammed with a unique ªSecret Keyº code and a
security code. The SKIM keeps the ªSecret Keyº code
in memory and sends the code over the CCD data
bus to the PCM, which also keeps this code in its
memory. The SKIM also sends the ªSecret Keyº code
to each of the programmed Smart Key transponders.
The security code is used by the assembly plant to
access the SKIS for initialization, or by the dealer
technician to access the system for service. The
SKIM also stores in its memory the Vehicle Identifi-
cation Number (VIN), which it learns through a PCI
bus message from the PCM during initialization.
The SKIM and the PCM both use software that
includes a rolling code algorithm strategy, which
helps to reduce the possibility of unauthorized SKIS
