PASSENGER SEAT SWITCH
DESCRIPTION
Vehicles equipped with power seats utilize a eight-
way power seat switch. This eight-way power seat
switch features two knobs ganged together on the
outboard seat cushion side shield (Fig. 5).
The switch is secured to the back of the seat cush-
ion side shield with two screws. However, the control
knobs for the seat switch unit must be removed
before the seat switch can be removed from the side
shield.
The power seat switch cannot be repaired. If one
switch is damaged or faulty, the entire power seat
switch unit must be replaced.
OPERATION
The power seat tracks can be adjusted in eight dif-
ferent ways using the power seat switches. See the
owner's manual in the vehicle glove box for more
information on the power seat switch functions and
the seat adjusting procedures.
When a power seat switch control knob or knobs
are actuated, a battery feed and a ground path are
applied through the switch contacts to the power seat
track or recliner adjuster motor. The selected
adjuster motor operates to move the seat track or
recliner through its drive unit in the selected direc-
tion until the switch is released, or until the travel
limit of the adjuster is reached. When the switch is
moved in the opposite direction, the battery feed and
ground path to the motor are reversed through the
switch contacts. This causes the adjuster motor to
run in the opposite direction.No power seat switch should be held applied in any
direction after the adjuster has reached its travel
limit. The power seat adjuster motors each contain a
self-resetting circuit breaker to protect them from
overload. However, consecutive or frequent resetting
of the circuit breaker must not be allowed to con-
tinue, or the motor may be damaged.
DIAGNOSIS AND TESTING - PASSENGER SEAT
SWITCH
(1) Remove switch, refer to Switch Removal and
Installation in this section.
(2) Using an ohmmeter, perform the Seat Switch
Continuity Test table and (Fig. 6). If there is no con-
tinuity at any of the switch positions, replace switch.

RECLINER MOTOR
DESCRIPTION
The eight-way power seat option includes an elec-
trically operated seat back recliner mechanism. The
only visible evidence of this option is the separate
power seat recliner switch control knob that is
located on the outboard seat cushion side shield, just
behind the other power seat switch control knob.
The power seat recliner unit is mounted in the
place of a seat hinge on the outboard side of the seat
(Fig. 8). The upper hinge plate of the power seat
recliner mechanism is secured with screws to the
seat back frame and is concealed beneath the seat
back trim cover and padding. The lower hinge plate
and the motor and drive unit of the power seat
recliner mechanism is secured with screws to the
seat cushion frame, and is concealed by the outboard
seat cushion side shield.
The power seat recliner cannot be repaired. If the
unit is faulty or damaged, it must be replaced. Refer
toBucket Seat Reclinerin Body for the service
procedure.
OPERATION
The power seat recliner includes a reversible elec-
tric motor that is secured to the lower hinge plate of
the recliner unit. The motor is connected to a gearbox
that moves the upper hinge plate of the power seat
recliner through a screw-type drive unit. The driver
side power seat recliner motor used on models
equipped with the optional memory system also has
a position potentiometer integral to the motor assem-
bly, which electronically monitors the motor position.

POWER SEAT TRACK
DESCRIPTION
The eight-way power seat options include a single
electrically operated power seat track unit located
under each front bucket seat (Fig. 9). The power seat
track unit replaces the standard equipment manual
seat tracks. The lower half of the power seat track is
secured at the front with two bolts to the floor panel
seat cross member, and at the rear with two bolts to
the floor panel. Four nuts secure the bottom of the
seat cushion frame to four studs on the upper half of
the power seat track unit.
The power seat track unit cannot be repaired, and
is serviced only as a complete unit. If any component
in this unit is faulty or damaged, the entire power
seat track unit must be replaced. Refer toBucket
Seat Track Adjusterin the Body section of the ser-
vice manual for the procedure.
OPERATION
The power seat track unit includes three reversible
electric motors that are secured to the upper half of
the track unit. Each motor moves the seat adjuster
through a combination of worm-drive gearboxes and
screw-type drive units. Each of the three driver side
power seat track motors used on models equipped
with the optional memory system also has a position
potentiometer integral to the motor assembly, which
electronically monitors the motor position.
The front and rear of the seat are operated by two
separate vertical adjustment motors. These motors
can be operated independently of each other, tiltingthe entire seat assembly forward or rearward; or,
they can be operated in unison by selecting the
proper power seat switch functions, which will raise
or lower the entire seat assembly. The third motor is
the horizontal adjustment motor, which moves the
seat track in the forward and rearward directions.
DIAGNOSIS AND TESTING - POWER SEAT
TRACK
Following are tests that will help to diagnose the
hard wired components and circuits of the power seat
system. However, if the vehicle is also equipped with
the optional memory system, these tests may not
prove conclusive in the diagnosis of the driver side
power seat. In order to obtain conclusive testing of
the driver side power seat with the memory system
option, the Programmable Communications Interface
(PCI) data bus network and all of the electronic mod-
ules that provide inputs to, or receive outputs from
the memory system components must be checked.
The most reliable, efficient, and accurate means to
diagnose the driver side power seat with the memory
system option requires the use of a DRBtscan tool
and the proper Diagnostic Procedures manual. The
DRBtscan tool can provide confirmation that the
PCI data bus is functional, that all of the electronic
modules are sending and receiving the proper mes-
sages on the PCI data bus, and that the memory sys-
tem is receiving the proper hard wired inputs and
relaying the proper hard wired outputs to perform its
driver side power seat functions.
WARNING: SOME VEHICLES ARE EQUIPPED WITH
SEATBACK MOUNTED AIRBAGS. BEFORE
ATTEMPTING TO DIAGNOSE OR SERVICE ANY
SEAT OR POWER SEAT SYSTEM COMPONENT
YOU MUST FIRST DISCONNECT AND ISOLATE THE
BATTERY NEGATIVE CABLE. THEN WAIT TWO MIN-
UTES FOR THE SYSTEM CAPACITOR TO DIS-
CHARGE BEFORE FURTHER SYSTEM SERVICE.
THIS IS THE ONLY SURE WAY TO DISABLE THE
AIRBAG SYSTEM. FAILURE TO DO SO COULD
RESULT IN ACCIDENTAL AIRBAG DEPLOYMENT
AND POSSIBLE PERSONAL INJURY.
Actuate the power seat switch to move all three
power seat track adjusters in each direction. The
power seat track adjusters should move in each of
the selected directions. If a power seat track adjuster
fails to operate in only one direction, move the
adjuster a short distance in the opposite direction
and test again to be certain that the adjuster is not
at its travel limit. If the power seat track adjuster
still fails to operate in only one direction, refer to
Power Seat Switchin the Diagnosis and Testing
section of this group. If the power seat track adjuster

PASSENGER AIRBAG
DESCRIPTION
WARNING: NEVER DISASSEMBLE THE PASSEN-
GER AIRBAG, THE PASSENGER AIRBAG HAS NO
SERVICEABLE PARTS.
The Passenger Airbag is located beneath the
instrument panel and pad assembly. The airbag is
mounted to the back side of the instrument panel
reinforcement.
The instrument panel top pad is the most visible
part of the passenger airbag system. Located under
the instrument panel top pad are the airbag door, the
passenger airbag cushion and the airbag cushion
supporting components.
The passenger airbag includes a magnesium hous-
ing within which the cushion and inflator are
mounted and sealed.
Following a passenger airbag deployment, the pas-
senger airbag and the instrument panel must be
replaced. The passenger airbag cannot be repaired,
and must be replaced if deployed or damaged in any
way.
OPERATION
The passenger airbag is equipped with two infla-
tors, each with three levels of pressure output. The
inflators seal the hole in the airbag cushion so it can
discharge the gas it produces directly into the cush-
ion when supplied with the proper electrical signal.
Following an airbag deployment, the airbag cushion
quickly deflates by venting this gas through the
cushion material towards the instrument panel.
The passenger airbag is secured with screws to the
instrument panel beneath the instrument panel top
pad and above the glove box opening. The instrumentpanel top pad above the glove box opening conceals
the airbag door and a predetermined hinge line
beneath its decorative cover. Upon airbag deploy-
ment, the top pad will bend at the hinge line and the
door will fold back out of the way onto the top of the
instrument panel.
WHEN THE FRONT AIRBAG SYSTEM IS
DEPLOYED BECAUSE OF A COLLISION, THE
FOLLOWING MUST BE REPLACED:
²COMPLETE STEERING COLUMN ASSEMBLY
²LOWER STEERING COUPLER
²STEERING WHEEL
²STEERING COLUMN CLOCK SPRING
²DRIVER AIRBAG COVER/HORN SWITCH
²DRIVER AIRBAG
²PASSENGER AIRBAG
²UPPER INSTRUMENT PANEL WITH PAD
CARE OF UNDEPLOYED AIRBAGS
Airbags must be stored in their original special
container until used for service. At no time should a
source of electricity be permitted near the inflator on
the back of an airbag. When carrying or handling an
undeployed airbag, the trim side of the airbag should
be pointing away from the body to minimize possibil-
ity of injury if accidental deployment occurs. Do not
place undeployed airbag face down on a solid surface,
the airbag will propel into the air if accidental
deployment occurs.
STANDARD PROCEDURE - DEPLOYED
PASSENGER AIRBAG CLEAN UP
Roll or fold the passenger airbag towards the
instrument panel surface and close the door over the
folded bag. Then tape the door shut.
Use a vacuum cleaner to remove any residual pow-
der from the vehicle interior. Work from the outside
in to avoid kneeling or sitting in a contaminated
area. Vacuum the heater and A/C outlets as well. If
HVAC was in RECIRC mode at time of airbag
deployment, operate HVAC blower on low speed/heat
and vacuum powder residue expelled from the heat
outlets. Multiple vacuum cleaning may be necessary
to decontaminate the interior of the vehicle.
SERVICE OF DEPLOYED AIRBAG
If a Passenger Airbag has been deployed, but not
due to a collision, replace the following:
²Passenger Airbag
²Upper instrument panel with pad
The component above must be replaced because
they cannot be reused. Inspect the heat duct near the
passenger airbag for any damage replace as neces-
sary. Replace any other passenger airbag system
components if damaged.
8O - 6 RESTRAINTSRS
OCCUPANT RESTRAINT CONTROLLER (Continued)

If the driver applies the brakes, canceling auto-
matic speed control operation with the transaxle still
in THIRD gear, the TCM maintains this gear until
the driver opens the throttle at least 6 degrees to
avoid an inappropriate upshift. The upshift is also
delayed for 2.5 seconds after reaching the 6 degrees
throttle opening in anticipation that the driver might
open the throttle enough to require THIRD gear.
This will avoid unnecessary and disturbing transmis-
sion cycling. If the automatic speed control RESUME
feature is used after braking, the upshift is delayed
until the set speed is achieved to reduce cycling and
provide better response.
DIAGNOSIS AND TESTING - ROAD TEST
Perform a vehicle road test to verify reports of
speed control system malfunction. The road test
should include attention to the speedometer. Speed-
ometer operation should be smooth and without flut-
ter at all speeds.
Flutter in the speedometer indicates a problem
which might cause surging in the speed control sys-
tem. The cause of any speedometer problems should
be corrected before proceeding. Refer to the Instru-
ment Panel and Gauges for speedometer diagnosis.
If a road test verifies an inoperative system, and
the speedometer operates properly, check for:²A Diagnostic Trouble Code (DTC). If a DTC
exists, conduct tests per the Powertrain Diagnostic
Procedures service manual.
²A misadjusted brake (stop) lamp switch. This
could also cause an intermittent problem.
²Loose or corroded electrical connections at the
servo. Corrosion should be removed from electrical
terminals and a light coating of Mopar Multipurpose
Grease, or equivalent, applied.
²Leaking vacuum reservoir.
²Loose or leaking vacuum hoses or connections.
²Defective one-way vacuum check valve.
²Secure attachment at both ends of the speed
control servo cable.
²Smooth operation of throttle linkage and throttle
body air valve.
²Conduct electrical test at PCM.
²Failed speed control servo. Do the servo vacuum
test.
CAUTION: When test probing for voltage or conti-
nuity at electrical connectors, care must be taken
not to damage connector, terminals or seals. If
these components are damaged, intermittent or
complete system failure may occur.

VEHICLE THEFT SECURITY
DESCRIPTION
VEHICLE THEFT SECURITY SYSTEM
The Vehicle Theft Security System (VTSS) is
designed to protect against whole vehicle theft. The
system monitors vehicle doors, hood, liftgate, and
ignition action for unauthorized operation. The alarm
activates:
²Sounding of the horn
²Flashing of the park and tail lamps
²Flashing of the headlamps
²An engine kill feature (without SKIS)
SENTRY KEY IMMOBILIZER SYSTEM
The Sentry Key Immobilizer System (SKIS) is
available as a factory-installed option on this vehicle.
It is designed to provide passive protection against
unauthorized vehicle use by disabling the engine,
after two (2) seconds of running, whenever an invalid
key is used to start the vehicle. The SKIS is active
whenever the ignition is on and does not require any
customer intervention. The primary components of
the system are the Sentry Key Immobilizer Module
(SKIM), Sentry Key (ignition key w/ a transponder
molded into the head), indicator light, Body Control
Module (BCM), and the Powertrain Control Module
(PCM). The SKIM is mounted to the steering column
with the molded, integral antenna mounted on the
light halo surrounding the ignition lock cylinder. The
indicator light, is located in the message center.
OPERATION
VEHICLE THEFT SECURITY SYSTEM
Upon failure of proper SKIM communication to the
PCM, the PCM will shut off fuel after two seconds ofrun time. The engine will not re-crank on the key
cycle that the failure occurred, a full key down
sequence must be performed for the engine to crank
again. After six consecutive fuel shut-offs, the engine
will no longer crank on subsequent key cycles. The
failure must be corrected and a valid communication
process between the SKIM and the PCM must occur
for the engine to crank and start again.
The electronics for the VTSS are part of the Body
Control Module (BCM). The system is armed when
the vehicle is locked using the:
²Power door lock switches (with any door ajar)
²Remote Keyless Entry transmitter.
²Door Cylinder Lock Switches.
For vehicles equipped with SKIS, the doors do not
have to be locked to enable the fuel shut off feature.
After the vehicle is locked and the last door is
closed, the set LED indicator in the top cover will
flash quickly for 16 seconds, indicating that arming
is in progress. If no monitored systems are activated
during this period, the system will arm. The LED
will extinguish unless the liftgate is open. If the lift-
gate is open, the LED will flash at a slower rate.
This indicates that the system is armed. If fault is
detected on any key cylinder input, the indicator
LED will remain solid during the arming process,
although the system will still arm. If the indicator
LED does not illuminate at all upon door closing it
indicates that the system is not arming.
Passive disarming occurs upon normal vehicle
entry by unlocking either door with the ignition key/
remote transmitter. This disarming will also halt the
alarm once it has been activated.
A tamper alert exists to notify the driver that the
VTSS had been activated. This alert consists of 3
horn pulses when the vehicle is disarmed.
RSVEHICLE THEFT SECURITY8Q-1

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.
If the VTSS is triggered, the horn will pulse, head-
lamps/marker lamps will flash, and the VTSS warn-
ing lamp will flash. If BCM determines the threat to
be false and the VTSS is not triggered again, the sys-
tem will shut down and rearm itself after three min-
utes. 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. The engine compartment sec-
tion and the passenger compartment section. If a
malfunction occurs in the engine compartment sec-
tion, the passenger compartment section would still
arm and function normally.
NOTE: If hood is not secure during the arming
sequence, the lamp will stay lit and not flash. The
system will arm with hood not secured (hood ajar
switch closed) and the liftgate open (liftgate ajar
switch closed). System will not arm if passenger
compartment is not secure (all switches closed)
ARMING THE VTSS - METHOD A
(1) With the key removed from the ignition lock
and any door open (excluding liftgate), actuate one of
the following:
²Power door lock button to LOCK,
²Key fob LOCK button
²Door lock key cylinder to locked position.
(2) Close all opened doors. Liftgate can remain
open.
(3) After the last door is closed, an arming time-
out period of sixteen seconds will start, then the
VTSS will become armed.
ARMING THE VTSS - METHOD B
Actuating the key fob transmitter LOCK button,
key locking the front doors or liftgate with the doors
closed and the ignition locked will begin the arming
time-out period. If method A, 16 second time-out
sequence was in process when method B was actu-
ated, the 16 second time-out will restart from the
time of the second actuation.
If the security lamp 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:
²Opening any door.
²Opening the hood
²Turning the ignition to the ON, ACC, or
UNLOCK position.
²Opening liftgate without first receiving a RKE
input or liftgate 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 IIItscan 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 IIItscan tool as
described in the appropriate Body Diagnostic Proce-
dures manual.
