designed to provide safe, reliable, centralized and
convenient to access distribution of the electrical cur-
rent required to operate all of the many standard
and optional factory-installed electrical and electronic
powertrain, chassis, safety, comfort and convenience
systems. At the same time, these systems were
designed to provide centralized locations for conduct-
ing diagnosis of faulty circuits, and for sourcing the
additional current requirements of many aftermarket
vehicle accessory and convenience items.
These power distribution systems also incorporate
various types of circuit control and protection fea-
tures, including:
²Fuses
²Fuse cartridges
²Fusible links
²Automatic resetting circuit breakers
²Relays
²Flashers
²Timers
²Circuit splice blocks.
The power distribution system for this vehicle con-
sists of the following components:

²Fuse Block
Following are general descriptions of the major
components in the power distribution system. Refer
to the owner's manual in the vehicle glove box for
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
diagrams.

The fusible link, fuses and relays are available for
service replacement. The PDC unit cannot be
repaired and is only serviced as a unit with the
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
circuit or the fuse block housing is faulty or dam-
aged, the entire fuse block and instrument panel
wire harness assembly must be replaced.

first turn) will cause all vehicle doors to unlock elec-
trically. When this feature is disabled, all vehicle
doors will be unlocked electrically upon the first turn
of a key cylinder to the UNLOCK position. The vehi-
cle is locked electrically by turning the key cylinder
to the LOCK position once, regardless of the state of
the double activation unlock feature.
POWER DOOR LOCKS
The Remote Keyless Entry (RKE) Module actuates
the power door lock relays when a door lock switch is
activated. If the door lock switch is pressed for longer
than eight consecutive seconds, the RKE module will
de-energize the door lock motors.
The system includes the rolling door locking fea-
ture. The vehicle is shipped with the system enabled.
When the system is disabled the door locks will work
by use of the door lock switches and the Remote Key-
less Entry system only. When the rolling door lock
system is enabled, the RKE module will automati-
cally lock all the vehicle doors when all of the follow-
ing conditions are met:
²All doors are closed
²The vehicle speed exceeds 15 +/- 1 mph.
²The throttle position sensor tip-in is greater
than 10 +/- 2 degrees.
The RKE module will automatically re-lock all
doors if the above conditions are met and if any of
the doors become ajar and then closed again.
The enabling/disabling of the rolling door lock fea-
ture is customer programmable, as well as program-
mable with the DRB IIItscan tool.
The power lock motors are also equipped with a
thermal protection system which prevents the motors
from burning out. The motors may chatter if they are
continuously activated.
CHILD PROTECTION LOCKS
The child protection locks are on the rear doors
only. The lock, when engaged, will disable the inside
door handle from opening the door. The lock is part
of the latch/lock assembly. The lock is engaged by
moving a lever that is located on the rearward inside
edge of the door.
DOOR LOCK INHIBIT
With the key in the ignition switch and the driver
door open, the Remote Keyless Entry (RKE) Modulewill ignore the command to lock the power door locks
via the interior driver door lock switch. Once the key
is removed, or the driver door is closed, the RKE
module will allow the power door locks to lock via the
interior door lock switches.
DIAGNOSIS AND TESTING
DOOR LOCK MOTOR
(1) Make certain battery is in normal condition
and fuses powering the RKE module aren't blown
before circuits are tested.
(2) To determine which motor is faulty, check each
individual door for electrical lock and unlock or dis-
connect the motor connectors one at a time, while
operating the door lock switch.
(3) In the event that none of the motors work, the
problem maybe caused by a shorted motor, a bad
switch or a bad relay internal to the RKE module.
Disconnecting a defective motor will allow the others
to work.
(4) To test an individual door lock motor, discon-
nect the electrical connector from the motor.
(5) To lock the door, connect a 12 volt power source
to one pin of the lock motor and a ground wire to the
other pin.
(6) To unlock the door, reverse the wire connec-
tions at the motor pin terminals.
(7) If these results are NOT obtained, replace the
motor.
DOOR LOCK SWITCH
(1) Remove the switch from its mounting location,
and disconnect from vehicle wiring harness. Refer to
Door Lock Switch Removal and Installation in this
section.
(2) Using an ohmmeter, refer to Door Lock Switch
Resistance Test table to determine if switch resis-
tance is correct in the Lock and Unlock switch posi-
tions. Refer to Group 8W-Wiring Diagrams for
harness connector pin-outs.

DESCRIPTION AND OPERATION (Continued)

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.
DIAGNOSIS AND TESTING
REMOTE KEYLESS ENTRY MODULE
For procedures on diagnosing and testing the RKE
Module's RKE functions, refer to the proper Body
Diagnostic Procedures Manual.
DECKLID RELEASE SOLENOID
(1) Confirm operation of RKE transmitter(s) by
actuating Lock and Unlock functions.
(2) Confirm lead is connected to deck lid release
solenoid.
(3) Unplug lead, and use an ohmmeter to verify
continuity of connection between pin 2 of the harness
connector and ground. Refer to Group 8W-Wiring
Diagrams for Connector Pin-Outs.
(4) Connect test light to pin 1 of the harness con-
nector and actuate decklid release button on trans-
mitter. Refer to Group 8W-Wiring Diagrams for
Connector Pin-Outs.
(5) If test light comes on, the wiring circuit
between the RKE module and the solenoid is func-
tional, and the decklid solenoid should be replaced.
(6) If test light does not come on, refer to the
proper Body Diagnostic Procedures Manual for fur-
ther troubleshooting information.
SERVICE PROCEDURES
HORN CHIRP TOGGLE
The toggling of the horn chirp (between enabled

DRB lllTPROGRAMMING
When using the DRB IIItscan tool, select:
(1) ªTheft Alarmº
(2) ªVTSSº
(3) ªMiscellaneousº
and then the desired function.
CUSTOMER PROGRAMMING
Using a transmitter programmed to the RKE Mod-
ule, the status of the horn chirp may be toggled by
the customer.
NOTE: The RKE Module is responsible for keeping
track of the horn chirp status; thus this procedure
does not need to be repeated for each transmitter
programmed to the system.

memory to determine whether a valid key is in the
ignition lock cylinder.
The Sentry Key transponder cannot be repaired
and, if faulty or damaged, it must be replaced.
SENTRY KEY IMMOBILIZER SYSTEM
INDICATOR LAMP
The Sentry Key Immobilizer System (SKIS) uses
the Vehicle Theft Security System (VTSS) indicator
LED to give an indication when the SKIS is faulty or
when the vehicle has been immobilized due to the
use of an invalid ignition key. The LED is controlled
by the instrument cluster circuitry based upon mes-
sages received from the Sentry Key Immobilizer
Module (SKIM) through the Body Control Module
(BCM) on the Programmable Communication Inter-
face (PCI) bus.
The SKIM sends messages to the instrument clus-
ter, via the BCM, to turn the LED on for about three
seconds when the ignition switch is turned to the ON
position as a bulb test. After completion of the bulb
test, the SKIM sends PCI bus messages to keep the
LED off for a duration of about one second. Then the
SKIM sends messages to the instrument cluster cir-
cuitry to turn the LED on or off based upon the
results of the SKIS self-tests. If the VTSS indicator
LED comes on and stays on after the bulb test, it
indicates that the SKIM has detected a system mal-
function and/or that the SKIS has become inopera-
tive. If the SKIM detects an invalid key when the
ignition switch is turned to the ON position, it sends
messages to the instrument cluster to flash the VTSS
indicator LED.
The SKIM can also send messages to the instru-
ment cluster to flash the LED and to generate a sin-
gle audible chime tone. These functions serve as an
indication to the customer that the SKIS has been
placed in its ªCustomer Learnº programming mode.
See Sentry Key Immobilizer System Transponder
Programming in this group for more information on
the ªCustomer Learnº programming mode.
The VTSS indicator LED uses a replaceable Light
Emitting Diode (LED) on the instrument cluster elec-
tronic circuit board. Refer to Group 8E - Instrument
Panel Systems for Cluster Lamp Removal and Instal-
lation. If the VTSS indicator LED comes on and
stays on after the bulb test function, diagnosis of the
SKIS should be performed with a DRB IIItscan tool
and the proper Body Diagnostic Procedures Manual.
TRIGGERING THE VTSS
After the VTSS is armed, any of the following will
trigger the system:
²Opening any door.
²Opening the hood.
²Removing the trunk lock cylinder.²Turning the ignition to the RUN/START position
with an invalid Sentry Key.
NOTE: The ignition switch can be turned to the
accessory position without triggering the alarm sys-
tem.
