OCCUPANT RESTRAINT
CONTROLLER
DESCRIPTION
The front driver and passenger airbag system is
designed to reduce the risk of fatality or serious
injury, caused by a frontal impact of the vehicle.
The Occupant Restraint Controller (ORC) contains
the impact sensor and energy reserve capacitor. It is
mounted on a bracket, under the instrument panel,just forward of the storage bin. The ORC monitors
the system to determine the system readiness. The
ORC contains on-board diagnostics and will light the
AIRBAG warning lamp in the message center when a
problem occurs.
OPERATION
The impact sensor provides verification of the
direction and severity of the impact. One impact sen-
sor is used. It is located inside the Occupant
Restraint Controller (ORC). The impact sensor is an
accelerometer that senses deceleration. The decelera-
tion pulses are sent to a microprocessor which con-
tains a decision algorithm. When an impact is severe
enough to require airbag protection, the ORC micro-
processor sends a signal that completes the electrical
circuit to the driver and passenger airbags. The
impact sensor is calibrated for the specific vehicle
and reacts to the severity and direction of an impact.
REMOVAL
NOTE: Diagnose the ORC using the service/diag-
nostic manual.
(1) Disconnect and isolate the battery negative
cable.
(2) Remove storage bin from instrument panel.
Refer to Body, Instrument Panel, Storage Bin,
Removal.

WARNING: DO NOT INSTALL ORC IF MOUNTING
LOCATION IS DEFORMED OR DAMAGED.
CAUTION: Use correct screws when installing the
ORC.
(1) Install the ORC assembly into vehicle.
(2) Connect the wire connector to the ORC.
(3) Install three bolts holding ORC to floor
bracket. Torque bolts to 7.3 - 9.6 N´m (65 to 85 in.
lbs.)
(4) Install the storage bin onto the instrument
panel. Refer to Body, Instrument Panel, Storage Bin,

OPERATION
The Transmission Control Module (TCM) first
senses that the speed control is set. If the set speed
is exceeded by more than 4 mph (6.5 km/hr) and the
throttle is closed, the TCM causes the transaxle to
downshift to THIRD gear. After downshifting, the
automatic speed control resumes normal operation.
To ensure that an upshift is appropriate after the set
speed is reached, the TCM waits until the speed con-
trol system opens the throttle at least 6 degrees
before upshifting to OVERDRIVE again.
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 Cluster 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 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
ignition housing. 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 of
run 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.

SKIM in addition to being cut to match the mechan-
ical coding of the ignition lock cylinder. Refer to Elec-
trical, Vehicle Theft Security, Transponder Key,
Standard Procedure - Transponder Programming.
The Sentry Key's transponder is within the range
of the SKIM's transceiver antenna ring when it is
inserted into the ignition lock cylinder. When the
ignition switch is turned to the ON position, the
SKIM communicates with the Sentry Key via a radio
frequency (RF) signal. The SKIM determines if a
valid key is present based on the information it
receives from the Sentry Key. If a valid key is
detected, that fact is communicated to the PCM via
the PCI bus and the vehicle is allowed to continue
running. If an invalid key is received by the PCM or
no status at all is communicated, the vehicle will
stall after two (2) seconds of running. The indicator
light will be flashing at this point. The Sentry Key's
transponder can not be repaired. If it is faulty or
damaged, it must be replaced.
Common communication problems:
²Two transponder keys too close together.
²Speed Pass too close to transponder key.
Solid indicator that there is a system failure.
²Loss of PCM communication.
²Failed antenna circuit.
STANDARD PROCEDURE - TRANSPONDER
PROGRAMMING
USING A DRB IIITSCAN TOOL
All Sentry Keys included with the vehicle are pre-
programmed to work with the Sentry Key Immobi-
lizer System (SKIS) when it is shipped from the
factory. The Sentry Key Immobilizer Module (SKIM)
can be programmed to recognize up to a total of eight
Sentry Keys. When programming a blank Sentry Key
transponder, the key must first be cut to match the
ignition lock cylinder of the vehicle for which it will
be used. The vehicle's four digit PIN code will be
required to complete this task since you will need it
to enter the Secured Access Mode in the SKIM. The
following steps must be completed using a DRB IIIt
scan tool:
(1) Insert the blank key into the ignition and turn
it to the RUN position.
(2) Using a DRB IIItscan tool, select9Theft
Alarm,99SKIM,99Miscellaneous,9and then9Program
New Key.9
(3) Enter the four digit PIN code using the DRB
IIItscan tool. When programming is completed, the
SKIM will exit Secured Access Mode and the DRB
IIItscan tool will display the results of your attempt
to program the key. One of five distinct results may
be displayed. All five are listed below:
²(Programming Successful(is displayed if the
Sentry Key programming is successful.
²(Learned Key in Ignition(is displayed if the
key in the ignition has already been programmed
into that vehicle's SKIM.
²(Eight Keys Already Learned (At The Maxi-
mum) Programming Not Done(is displayed if
eight keys have already been programmed into the
SKIM. In this case, if a new key needs to be added
due to a lost or defective key, the9Erase All Keys9
command (which requires entering the Secured
Access Mode) has to be performed. Following the
9Erase All Keys9command, all keys that will be used
to operate the vehicleMUSTbe reprogrammed to
the SKIM.
²(Programming Not Attempted(is displayed
after an9Erase All Keys9function is executed.
²(Programming Key Failed(is displayed if fur-
ther diagnosis is required.
To learn additional keys, turn the ignition OFF,
remove the learned key, insert the next new blank
key, and repeat the steps from the beginning.
ªCUSTOMER LEARNº MODE
This feature is only available on domestic vehicles
or those which have a U.S. country code designator.
This procedure requires access to at least two valid
Sentry Keys. If two valid Sentry Keys are not avail-

able, Sentry Key programming will require the use of
a DRB IIItscan tool.
The steps required to program Sentry Keys with
two valid Sentry Keys follows:
(1) Obtain the blank Sentry Key(s) that need to be
programmed. Cut the keys to match the ignition lock
cylinder mechanical key codes.
(2) Insert one of the two valid Sentry Keys into the
ignition switch and turn the ignition switch to the
ON position.
(3) After the ignition switch has been in the ON
position for longer than three seconds, but no more
than fifteen seconds, cycle the ignition switch back to
the OFF position. Replace the first valid Sentry Key
in the ignition lock cylinder with the second valid
Sentry Key and turn the ignition switch back to the
ON position. The second valid Sentry Key must be
inserted within 15 seconds of removing the first valid
Sentry key.
(4) About ten seconds after the completion of Step
3, the indicator light will start to flash and a single
audible chime tone will sound to indicate that the
system has entered the9Customer Learn9program-
ming mode.
(5) Within sixty seconds of entering the9Customer
Learn9programming mode, turn the ignition switch
to the OFF position, replace the valid Sentry Key
with a blank Sentry Key transponder, and turn the
ignition switch back to the ON position.
(6) About ten seconds after the completion of Step
5, a single audible chime tone will sound and the
indicator light will stop flashing and stay on solid for
three seconds and then turn off to indicate that the
blank Sentry Key has been successfully programmed.
The SKIS will immediately exit the9Customer
Learn9programming mode and the vehicle may be
started using the newly programmed Sentry Key.
These steps must be completed in their entirety for
each additional Sentry Key to be programmed. If any
of the above steps are not completed in the given
sequence, or within the allotted time, the SKIS will
exit the9Customer Learn9programming mode and
the programming will be unsuccessful. The SKIS will
also automatically exit the9Customer Learn9pro-
gramming mode if:
²It sees a non-blank Sentry Key when it should
see a blank.
²If it has already programmed eight (8) valid
Sentry Keys.
²If the ignition switch is turned to the OFF posi-
tion for more than about fifty (50) seconds.NOTE: If you attempt to start the vehicle while in
ªCustomer Learnº mode (LED flashing), the vehicle
will behave as though an invalid key is being used
(i.e. the engine will stall after two (2) seconds of
running). No faults will be logged.
NOTE: Once a Sentry Key has been programmed to
a particular vehicle, it cannot be used on any other
vehicle.
VTSS/SKIS INDICATOR LAMP
DESCRIPTION
The Sentry Key Immobilizer System (SKIS) uses
an indicator light to convey information on the status
of the system to the customer. This light is shared
with the Vehicle Theft Security System (VTSS). The
light is located in the Message Center. The indicator
light is controlled by the Body Control Module (BCM)
based upon messages it receives from the Sentry Key
Immobilizer Module (SKIM) on the PCI bus.
OPERATION
The BCM performs a four second bulb check,
regardless of SKIM messages. After the bulb check,
the lamp is controlled according to SKIM messages.
Then, the SKIM sends messages to the BCM to oper-
ate the light based upon the results of the SKIS self
tests. The light may be actuated in two possible
ways, flashing or on solid. If the light comes on and
stays on solid after a power-up test, this indicates
that the SKIM has detected a system malfunction. If
the SKIM detects an invalid key when the ignition
switch is moved to the ON position, it sends a mes-
sage on the PCI bus to the BCM, to flash the light.
The SKIM can also send a message to flash the light
and generate a single audible chime at the same
time. These two events occurring simultaneously
indicate that the SKIS has been placed into the9Cus-
tomer Learn9mode. Refer to Electrical, Vehicle Theft
Security, Transponder Key, Standard Procedure -
Transponder Programming for more information on
the9Customer Learn9mode. If the light comes on
and stays on after the power-up test, diagnosis of the
SKIS should be performed using a DRB IIItscan tool
and the appropriate Body Diagnostic Procedures
manual. The light is not a serviceable component.

OPERATION
FRONT WIPER/WASHER SYSTEM
The windshield washer circuit is protected by a 15
amp Cartridge Fuse located in the IPM. The wiper
motor has permanent magnetic fields. The speeds are
determined by current flow to the appropriate set of
brushes inside the motor. The current flow is con-
trolled by the multi-function switch. The high speed/
low speed relays are located in the IPM. The speed
sensitive intermittent wiper is controlled by the Body
Control Module (BCM). The intermittent mode, with
the vehicle traveling greater than 10.4 mph, has a
range of 0.5 to 18 seconds. With the vehicle traveling
less than 10.4 mph, the time delay doubles to a
range of 1 to 36 seconds. The wiper arms will park at
the base of the windshield just above the cowl cover
after the wiper switch is turned OFF.
The windshield wiper motor and linkage is located
in an integral wiper unit at the rear of the engine
compartment. The wiper unit must be removed to
gain access to the wiper motor.
REAR WIPER/WASHER SYSTEM
When continuous rear wiper operation is required,
the BCM will provide ignition ON voltage to the rear
wiper motor. When the wiper switch is turned OFF,
the BCM provides circuit ground to operate the
motor until the wipe cycle is complete and the wiper
arm returns to the base of the rear window.
When intermittent rear wiper mode is selected, the
wiper motor will cycle every 7 seconds. The intermit-
tent delay time is also adjusted based upon vehicle
speed. With the vehicle traveling greater than 50
mph, the cycle changes to every 5 seconds.
DIAGNOSIS AND TESTING
DIAGNOSIS AND TESTING - FRONT WIPER
SYSTEM
The windshield wiper system operates in several
modes:
²Low and high speed normal wipe²Speed sensitive intermittent wipe
²Wipe after wash
²Park (switch OFF)
The windshield wiper circuits are continuously
monitored and controlled by the Body Control Mod-
ule (BCM). If a problem occurs in the electronic com-
ponents, wiring, switch (except integral motor park
switch) and wiper motor a Diagnostic Trouble Code
(DTC) will be stored in the BCM memory. DTC's can
be retrieved using a DRB IIItscan tool. Refer to the

FRONT WIPER ARMS
STANDARD PROCEDURE - FRONT WIPER ARM
ALIGNMENT
(1) Verify wiper blade element condition and wiper
arm spring tension. Run wipers in low speed mode
while applying water to the windshield. Observe the
wiper blade that is chattering or skipping across the
windshield. If the wiper element is not rolling over
when the wiper direction reverses, align the wiper
arm. The extension bar portion of the wiper arm
must be twisted in the proper direction to allow the
wiper element to roll over when the direction
reverses.
(2) Place two small adjustable wrenches placed 50
mm (2 in.) apart on the wiper arm extension rod.
(3) Twist the extension rod slightly in the opposite
direction that the element is laying on the wind-
shield while holding the wrench closest to the pivot
stationary.
