DRIVER AIRBAG
DESCRIPTION
The color-keyed, injection molded, thermoplastic
driver airbag protective trim cover is the most visible
part of the driver airbag (Fig. 18). The driver airbag
is located in the center of the steering wheel, where
it is secured with two screws to the armature of the
horn switch within the hub cavity of the four-spoke
steering wheel. Concealed beneath the driver airbag
trim cover are the folded airbag cushion, the airbag
cushion retainer, the airbag housing, the airbag infla-
tor, and the retainers that secure the inflator to the
airbag housing (Fig. 19). The airbag cushion, hous-
ing, and inflator are secured within an integral
receptacle molded into the back of the trim cover.

The airbag used in this model is a Next Genera-
tion-type that complies with revised federal airbag
standards to deploy with less force than those used
in some prior models. A radial deploying fabric cush-
ion with internal tethers is used. The airbag inflator
is a solid fuel, pyrotechnic-type unit with four studs
and is secured by four hex nuts to four studs on the
airbag cushion retainer ring to the back of the
stamped metal airbag housing. A keyed connector
receptacle on the driver airbag inflator connects the
inflator initiator to the vehicle electrical system
through a yellow-jacketed, two-wire pigtail harness of
the clockspring.
The driver airbag and trim cover unit cannot be
repaired, and must be replaced if deployed, faulty, or
in any way damaged.
OPERATION
The driver airbag is deployed by electrical signals
generated by the Airbag Control Module (ACM)
through the driver airbag squib circuit to the initia-
tor in the airbag inflator (Fig. 20). When the ACM
sends the proper electrical signal to the initiator the
electrical energy generates enough heat to initiate a
small pyrotechnic charge which, in turn, ignites
chemical pellets within the inflator. Once ignited,
these chemical pellets burn rapidly and produce a
large quantity of inert gas. The inflator is sealed to
the back of the airbag housing and a diffuser in the
inflator directs all of the inert gas into the airbag
cushion, causing the cushion to inflate. As the cush-
ion inflates, the driver airbag trim cover will split at
predetermined breakout lines, then fold back out of
the way. Following an airbag deployment, the airbag
cushion quickly deflates by venting the inert gas
towards the instrument panel through filtered vents
within the fabric used to construct the back (steering
wheel side) panel of the airbag cushion.
Some of the chemicals used to create the inert gas
may be considered hazardous while in their solid
state before they are burned, but they are securely

out and connector of the vehicle wire harness located
within the driver side front seat riser.
The seat belt switch cannot be adjusted or repaired
and, if faulty or damaged, the entire driver side seat
belt buckle unit must be replaced.
OPERATION
The seat belt switch is designed to control a path
to ground for the seat belt switch sense input of the
Electro-Mechanical Instrument Cluster (EMIC). The
seat belt switch contact is actuated by the seat belt
latch plate being inserted in to the buckle. When the
seat belt latch plate is inserted into the buckle far
enough to be engaged by the seat belt buckle latch,
the switch leaf contact opens the seat belt switch
sense circuit ground path; and, when the seat belt
latch plate is released and extracted from the seat
belt buckle latch the switch leaf contact is released,
closing the circuit to ground.
The seat belt switch is connected is series between
ground and the seat belt switch sense input of the
instrument cluster. The seat belt switch receives
ground at all times through its pigtail wire connec-
tion to the vehicle wire harness from another take
out of the vehicle wire harness. An eyelet terminal
connector on the vehicle wire harness ground take
out is secured under a nut to a ground stud located
on the floor panel within the driver side front seat
riser. The seat belt switch may de diagnosed using
conventional diagnostic tools and methods.
SEAT BELT TENSIONER
DESCRIPTION
Front seating position seat belt tensioners supple-
ment the standard driver and optional passenger air-
bags for all versions of this model. When equipped,
the seat belt tensioner is integral to the front seat
belt and retractor units, which are secured to the
inner B-pillars of the vehicle (Fig. 38). Each retractor
is concealed beneath the molded plastic B-pillar trim.
The seat belt tensioner consists primarily of a tubu-
lar steel housing, a piston, a cable, a torsion bar, and
a small pyrotechnically activated gas generator. All of
these components are located on one side of the
retractor spool on the outside of the retractor housing
except for the torsion bar, which serves as the spin-
dle upon which the retractor spool rotates. The seat
belt tensioner is controlled by the Airbag Control
Module (ACM) and is connected to the vehicle elec-
trical system through a dedicated take out of the
vehicle wire harness by a keyed, snap-fit molded
plastic connector insulator to ensure a secure connec-
tion.
The seat belt tensioner cannot be repaired and, if
faulty or damaged, the entire front seat belt and
retractor unit must be replaced. If the front airbags
have been deployed, the seat belt tensioners have
also been deployed. The seat belt tensioner is not
intended for reuse and must be replaced following a

WARNING: To avoid personal injury or death, on
vehicles equipped with airbags, disable the supple-
mental restraint system before attempting any
steering wheel, steering column, airbag, seat belt
tensioner, or instrument panel component diagno-
sis or service. Disconnect and isolate the battery
negative (ground) cable, then wait two minutes for
the system capacitor to discharge before perform-
ing further diagnosis or service. This is the only
sure way to disable the supplemental restraint sys-
tem. Failure to take the proper precautions could
result in accidental airbag deployment.
WARNING: To avoid personal injury or death, during
and following any seat belt service, carefully
inspect all seat belts, buckles, mounting hardware,
retractors, and anchors for proper installation, oper-
ation, or damage. Replace any belt that is cut,
frayed, or torn. Straighten any belt that is twisted.
Tighten any loose fasteners. Replace any belt that
has a damaged or inoperative buckle or retractor.
Replace any belt that has a bent or damaged latch
plate or anchor plate. Never attempt to repair a seat
belt component. Always replace damaged or faulty
seat belt components with the correct, new and
unused replacement parts listed in the
DaimlerChrysler Mopar Parts Catalog.
(1) Position the seat belt turning loop height
adjuster onto the inner B-pillar (Fig. 42).

B-pillar. (Refer to 23 - BODY/INTERIOR/B-PILLAR
TRIM - INSTALLATION).
(7) Reconnect the battery negative cable.
SIDE CURTAIN AIRBAG
DESCRIPTION
Optional side curtain airbags are available for this
model when it is also equipped with dual front air-
bags. These airbags are passive, inflatable, Supple-
mental Restraint System (SRS) components (Fig. 43).
This system is designed to reduce injuries to the
vehicle occupants in the event of a side impact colli-
sion.
Vehicles equipped with side curtain airbags have
two individually controlled curtain airbag units.
These airbag units are concealed and mounted above
the front door openings where they are each secured
to one of the roof side rails. Each folded airbag cush-
ion is contained within a channel in the molded plas-
tic garnish molding that extends along the roof rail
from the A-pillar at the front of the vehicle to just
behind the B-pillar. A tether extends down the A-pil-
lar from the front of the airbag cushion, where it is
secured to the base of the pillar near the belt line
with a screw.
The hybrid-type inflator for each airbag is con-
nected to the airbag cushion by a tubular manifold.
The inflator bracket and the airbag cushion channel
are located with a stamped metal lug to a bore in the
roof rail, then secured with screws at the A-pillar in
the front and the B-pillar in the rear. A two-wire pig-
tail wire is routed from the airbag inflator down the
B-pillar where it connects the unit to a take out of
the vehicle body wire harness with a keyed and
latched connector insulator.
The side curtain airbag unit cannot be adjusted or
repaired and must be replaced if deployed, faulty, or

VEHICLE THEFT SECURITY
DESCRIPTION
A vehicle theft alarm with a battery powered siren
is available as an option and includes interior moni-
toring, anti-tow away protection and rear window
monitoring based on the heater wires. The alarm is
automatically activated when the central locking sys-
tem is operated.
The alarm will sound when any of the following
occur:
²A door is opened
²A door is unlocked from inside the vehicle
²The hood is opened
²The vehicle is raised at the front or rear
²The trailer wire harness is disconnected
²Movements inside the vehicle
²The central locking is unlocked by a key at any
other door than the driver's door
The alarm is functional about 30 seconds after the
vehicle is locked using the RKE transmitter or the
key in the driver's door. Activation is indicated by the
indicator lights flashing three times and the warning
lamp flashing in the switch. If persons or animals
remain in the locked vehicle, the operator should
switch off the interior monitor to avoid a false alarm.
OPERATION
The anti-theft alarm is activated/deactivated by
locking/unlocking the vehicle with the remote trans-
mitter or with the key at the driver's door. The key
must be held in the locking position for more than
two seconds. Activation is indicated by the turn sig-
nal lights flashing once. Unlocking the vehicle at one
of the other doors will trigger an alarm.
The interior monitoring system included in the
anti-theft alarm is based on ultrasonics and triggersan alarm if an object intrudes the interior of the
vehicle or if any movement is detected inside the
vehicle. For proper and effective protection, all win-
dows and the sunroof must be closed.
To switch off the interior monitoring system and /
or the anti-tow away protection, a switch with LED
indicator light is provided in the switch panel. An
alarm button enables the operator to trigger an
alarm manually and to lock all doors if they are
closed. Triggering an alarm makes the horn sound
and the turn signals flash until the alarm is switched
off.
The anti-theft alarm control unit includes a gradi-
ent indicator as anti-tow away protection. The gradi-
ent indicator triggers an audible and visual alarm if
the vehicle is lifted (to tow away or to remove the
wheels). The alarm remains effective even if the bat-
tery is disconnected as the horn is powered by its
own battery. The interior monitoring system should
be switched off if people and/or animals are left in
the vehicle.

SENTRY KEY REMOTE ENTRY
MODULE
DESCRIPTION
The Sentry Key Remote Entry Module (SKREEM)
(Fig. 2) performs the functions of the Sentry Key
Immobilizer Module (SKIM) and the Remote Keyless
Entry (RKE) module.
SENTRY KEY IMMOBILIZER
The Sentry Key Immobilizer System (SKIS)
authenticates an electronically coded Transponder
Key placed into the ignition and sends a valid/invalid
key message to the Engine Control Module (ECM)
based upon the results. The ªVALID/INVALID KEYº
message communication is performed using a rolling
code algorithm. A ªVALID KEYº message must be
sent to the ECM within two seconds of ignition ON
to free the engine from immobilization. This Control-
ler Area Network (CAN) data bus message is sent to
the ECM after first going through the SKREEM. The
SKREEM is located behind the instrument cluster
and has a separately mounted antenna ring mounted
around the ignition cylinder (Fig. 3) which picks up
the transponder key signal.

REMOTE KEYLESS ENTRY (RKE)
The RKE transmitter uses radio frequency signals
to communicate with the Sentry Key Remote Entry
Module (SKREEM). The SKREEM is hardwired to
the Central Timer Module (CTM). When the operator
presses a button on the transmitter, it sends a spe-
cific request to the SKREEM. In turn, the SKREEM
sends the appropriate request to the CTM to unlock
the vehicle doors.
OPERATION
SENTRY KEY IMMOBILIZER
The Sentry Key Remote Entry Module (SKREEM)
receives an encrypted Radio Frequency (RF) signal
from the transponder key which is read by the
remotely mounted antenna ring at the ignition cylin-
der. The SKREEM then decrypts the signal and
broadcasts the requested remote commands to the
appropriate modules in the vehicle over the Control-
ler Area Network (CAN) data bus. A valid transpon-
der key ID must be incorporated into the RF signal
in order for the SKREEM to pass the message on to
the appropriate modules.
Automatic transponder key synchronization is done
by the SKREEM if a valid transponder key is
inserted into the ignition cylinder, and the ignition is
turned ON. This provides a maximum operation win-
dow for RKE functions.
Each Sentry Key Remote Entry System (SKREES)
consists of a SKREEM, an antenna ring mounted
around the ignition cylinder, and a transponder key.
Each system has a secret key code unique to that
system. The secret key is electronically coded in the
SKREEM and in all programmed transponder keys.
It is used for immobilization and RKE functions for
data security. In addition, each transponder key will
have a unique identification.
REMOTE KEYLESS ENTRY
After pressing the lock button on the RKE trans-
mitter, all of the door locks will lock, the illuminated
entry will turn off (providing all doors are closed),
and the VTSS (if equipped) will arm. After pressing
the unlock button, on the RKE transmitter, one time,
the driver door lock will unlock, the illuminated
entry will turn on the courtesy lamps, and the VTSS
(if equipped) will disarm. After pressing the unlock
button a second time, the remaining door locks will
unlock.
The SKREEM is capable of retaining up to 8 indi-
vidual access codes (8 transmitters). If the PRNDL is
in any position except park, the SKREEM will dis-
able the RKE. Use a diagnostic scan tool or the cus-
tomer programming method to program the RKE
system. However, the SKREEM will only allow RKE
programming when the ignition is in the ON posi-
tion, the PRNDL is in park position, and the VTSS
(if equipped) is disarmed.

TRANSPONDER KEY
DESCRIPTION
The Sentry Key Immobilizer System (SKIS) which
communicates with the Sentry Key Remote Entry
Module (SKREEM), uses a transponder chip that is
integral to each key fob (Fig. 6). Ignition keys are
supplied with the vehicle when it is shipped from the
factory. The transponder chip is located within the
Remote Keyless Entry (RKE) fob.
OPERATION
Each Sentry Key has a unique transponder identi-
fication code permanently programmed into it by the
manufacturer. Likewise, the Sentry Key Remote
Entry Module (SKREEM) has a unique ªSecret Key9
code programmed into it by the manufacturer as
well. When a Sentry Key is programmed into the
memory of the SKREEM, the SKREEM stores the
transponder identification code from the Sentry Key,
and the Sentry Key learns the ªSecret Keyº code
from the SKREEM. Once the Sentry Key learns the
ªSecret Keyº code of the SKREEM, it is also perma-
nently programmed into the transponder's memory.
The Sentry Key's transponder is within the range
of the SKREEM's transponder ring when it is
inserted into the ignition lock cylinder. When the
ignition switch is turned to the ON position, the
SKREEM communicates with the Sentry Key via a
radio frequency (RF) signal. The SKREEM deter-
mines if a valid key is present based on the informa-
tion it receives from the Sentry Key. If a valid key is
detected, that fact is communicated to the Engine
Control Module (ECM) via the Controller Area Net-
work (CAN) data bus and the vehicle is allowed to
continue running. If an invalid key is received by theECM or no status at all is communicated, the vehicle
will stall after two (2) seconds of running. The indi-
cator 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 ECM communication.
²Failed transponder ring circuit.

DESCRIPTION
HOW TO USE WIRING DIAGRAMS
DaimlerChrysler Corporation wiring diagrams are
designed to provide information regarding the vehi-
cles wiring content. In order to effectively use the
wiring diagrams to diagnose and repair
DaimlerChrysler Corporation vehicles, it is important
to understand all of their features and characteris-
tics.
Diagrams are arranged such that the power (B+)
side of the circuit is placed near the top of the page,
and the ground (B-) side of the circuit is placed near
the bottom of the page (Fig. 1).
All switches, components, and modules are shown
in the at rest position with the doors closed and the
key removed from the ignition (Fig. 2).Components are shown two ways. A solid line
around a component indicates that the component is
complete. A dashed line around the component indi-
cates that the component is being shown is not com-
plete. Incomplete components have a reference
number to indicate the page where the component is
shown complete.
It is important to realize that no attempt is made
on the diagrams to represent components and wiring
as they appear on the vehicle. For example, a short
piece of wire is treated the same as a long one. In
addition, switches and other components are shown
as simply as possible, with regard to function only.
SYMBOLS
International symbols are used throughout the wir-
ing diagrams. These symbols are consistent with
those being used around the world (Fig. 3).
