POWER WINDOWS
DESCRIPTION
The power window system allows each of the door
windows to be raised and lowered electrically by
actuating a switch on the center console. A master
switch on the front of the center console allows the
driver to raise or lower each of the passenger door
windows and to lock out the individual switches on
the rear of the center console from operation. The
power window system receives battery feed through
fuse 13 in the Power Distribution Center (PDC), only
when the ignition switch is in the RUN or ACCES-
SORY position.
OPERATION
WINDOW SWITCH
The power window switches control the battery
and ground feeds to the power window motors. Both
of the rear door power window switches receive their
battery and ground feeds through the circuitry of the
front window switch. When the power window lock-
out switch is in the Lock position, the battery feed
for the rear door window switches is interrupted.
WINDOW MOTOR
Front door window lift motors use permanent type
magnets. The B+ and ground applied at the motor
terminal pins will cause the motor to rotate in one
direction. Reversing current through the motor ter-
minals will cause the motor to rotate in the opposite
direction.
Refer to the appropriate wiring information. The
wiring information includes wiring diagrams, proper
wire and connector repair procedures, details of wire
harness routing and retention, connector pin-out
information and location views for the various wire
harness connectors, splices and grounds.

An occupant restraint system is standard factory-
installed safety equipment on this model. Available
occupant restraints for this model include both active
and passive types. Active restraints are those which
require the vehicle occupants to take some action to
employ, such as fastening a seat belt; while passive
restraints require no action by the vehicle occupants
to be employed (Fig. 1).
ACTIVE RESTRAINTS The active restraints for
this model include:
²Front Seat Belts- Both front seating positions
are equipped with three-point seat belt systems
employing a lower B-pillar mounted inertia latch-
type retractor, height-adjustable upper B-pillar
mounted turning loops, a traveling lower seat belt
anchor secured to the outboard side of the seat
frame, and a traveling end-release seat belt buckle
secured to the inboard side of the seat frame. Both
front seat belt buckles include an integral Hall-effect
seat belt switch that detects whether its respective
seat belt has been fastened.
²Rear Seat Belts- All three rear seating posi-
tions are equipped with three-point seat belt sys-
tems. The outboard seating position belts employ a
lower C-pillar mounted inertia latch-type retractor, a
fixed position upper C-pillar mounted turning loop,
and a fixed lower seat belt anchor secured to the
floor panel. The rear seat center seating position belt
has an inertia latch-type retractor that is integral to
the rear seat back panel, and a cable from the seat
back latch locks the center belt retractor spool unless
the seat back is fully latched. The rear seat center
seating position belt lower anchor is secured to the
floor panel. All three rear seat belts have fixed end-
release seat belt buckles secured to the floor panel, a
single buckle unit on the right side and a double
buckle unit on the left side.
²Child Seat Tether Anchors- All vehicles are
equipped with three, fixed-position, child seat tether
anchors. Two anchors are integral to the back of the
right rear seat back panel, and one is integral to the
left rear seat back panel.
PASSIVE RESTRAINTS The passive restraints
available for this model include the following:
²Dual Front Airbags- Multistage driver and
front passenger airbags are available for this model.
This airbag system is a passive, inflatable, Supple-
mental Restraint System (SRS) and vehicles with
this equipment can be readily identified by the ªSRS
- AIRBAGº logo molded into the driver airbag trim
cover in the center of the steering wheel and also
into the passenger airbag door on the instrument
panel above the glove box (Fig. 2). Vehicles with the
airbag system can also be identified by the airbag
indicator, which will illuminate in the instrument
cluster for about seven seconds as a bulb test eachtime the ignition switch is turned to the On position.
A pyrotechnic-type seat belt tensioner is integral to
the driver side front seat belt retractor mounted on
the lower B-pillar of all models equipped with dual
front airbags.
²Side Curtain Airbags- Optional side curtain
airbags are available for this model when it is also
equipped with dual front airbags. This airbag system
is a passive, inflatable, Supplemental Restraint Sys-
tem (SRS) and vehicles with this equipment can be
readily identified by a molded identification trim but-
ton with the ªSRS - AIRBAGº logo located on the
headliner above each B-pillar (Fig. 2).
The supplemental restraint system includes the
following major components, which are described in
further detail elsewhere in this service information:
²Airbag Control Module- The Airbag Control
Module (ACM) is also sometimes referred to as the
Occupant Restraint Controller (ORC). The ACM is
located on a mount on the floor panel transmission
tunnel, below the center of the instrument panel.
²Airbag Indicator- The airbag indicator is inte-
gral to the ElectroMechanical Instrument Cluster
(EMIC), which is located on the instrument panel in
front of the driver.
²Clockspring- The clockspring is located near
the top of the steering column, directly beneath the
steering wheel.
²Driver Airbag- The driver airbag is located in
the center of the steering wheel, beneath the driver
airbag trim cover.
²Driver Knee Blocker- The driver knee blocker
is a structural unit secured to the back side of and
integral to the instrument panel steering column
opening cover.
²Front Impact Sensor- Two front impact sen-
sors are used on vehicles equipped with dual front
airbags, one left side and one right side. One sensor

KJRESTRAINTS 8O - 3
RESTRAINTS (Continued)

is located on the back side of each vertical member of
the radiator support.
²Passenger Airbag- The passenger airbag is
located on the instrument panel, beneath the passen-
ger airbag door on the instrument panel above the
glove box on the passenger side of the vehicle.
²Passenger Knee Blocker- The passenger knee
blocker is a structural reinforcement that is integral
to and concealed within the glove box door.
²Seat Belt Tensioner- The seat belt tensioner
is integral to the driver side front seat belt retractor
unit on vehicles equipped with dual front airbags.
²Side Impact Airbag Control Module-Two
Side Impact Airbag Control Modules (SIACM) are
used on vehicles with the optional side curtain air-
bags, one left side and one right side. One SIACM is
located behind the B-pillar trim near the base of each
B-pillar.
²Side Curtain Airbag- In vehicles equipped
with this option, a side curtain airbag is located on
each inside roof side rail above the headliner, and
extends from the A-pillar to just beyond the C-pillar.
The ACM, both SIACMs, and the EMIC each con-
tain a central processing unit and programming that
allow them to communicate with each other using
the Programmable Communication Interface (PCI)
data bus network. This method of communication is
used by the ACM for control of the airbag indicator
on all models equipped with dual front airbags.
(Refer to 8 - ELECTRICAL/ELECTRONIC CON-
TROL MODULES/COMMUNICATION - DESCRIP-
TION).
Hard wired circuitry connects the supplemental
restraint system components to each other through
the electrical system of the vehicle. These hard wired
circuits are integral to several wire harnesses, which
are routed throughout the vehicle and retained by
many different methods. These circuits may be con-
nected to each other, to the vehicle electrical system,
and to the supplemental restraint system compo-
nents through the use of a combination of soldered
splices, splice block connectors, and many different
types of wire harness terminal connectors and insu-
lators. Refer to the appropriate wiring information.
The wiring information includes wiring diagrams,
proper wire and connector repair procedures, further
details on wire harness routing and retention, as well
as pin-out and location views for the various wire
harness connectors, splices and grounds.
OPERATION
ACTIVE RESTRAINTS The primary passenger
restraints in this or any other vehicle are the stan-
dard equipment factory-installed seat belts. Seat
belts are referred to as an active restraint because
the vehicle occupants are required to physically fas-ten and properly adjust these restraints in order to
benefit from them. See the owner's manual in the
vehicle glove box for more information on the fea-
tures, use and operation of all of the factory-installed
active restraints.
PASSIVE RESTRAINTS The passive restraints
system is referred to as a supplemental restraint sys-
tem because they were designed and are intended to
enhance the protection for the vehicle occupants of
the vehicleonlywhen used in conjunction with the
seat belts. They are referred to as passive systems
because the vehicle occupants are not required to do
anything to make them operate; however, the vehicle
occupants must be wearing their seat belts in order
to obtain the maximum safety benefit from the facto-
ry-installed supplemental restraint systems.
The supplemental restraint system electrical cir-
cuits are continuously monitored and controlled by a
microprocessor and software contained within the
Airbag Control Module (ACM) and, on vehicles
equipped with the side curtain airbags, both Side
Impact Airbag Control Modules (SIACM). An airbag
indicator in the ElectroMechanical Instrument Clus-
ter (EMIC) illuminates for about seven seconds as a
bulb test each time the ignition switch is turned to
the On or Start positions. Following the bulb test,
the airbag indicator is turned on or off by the ACM
to indicate the status of the supplemental restraint
system. If the airbag indicator comes on at any time
other than during the bulb test, it indicates that
there is a problem in the supplemental restraint sys-
tem electrical circuits. Such a problem may cause air-
bags not to deploy when required, or to deploy when
not required.
Deployment of the supplemental restraints
depends upon the angle and severity of an impact.
Deployment is not based upon vehicle speed; rather,
deployment is based upon the rate of deceleration as
measured by the forces of gravity (G force) upon the
impact sensors. When an impact is severe enough,
the microprocessor in the ACM or the SIACM signals
the inflator unit of the airbag module to deploy the
airbag. The seat belt tensioner is provided with a
deployment signal by the ACM in conjunction with
the driver airbag. During a frontal vehicle impact,
the knee blockers work in concert with properly fas-
tened and adjusted seat belts to restrain both the
driver and the front seat passenger in the proper
position for an airbag deployment. The knee blockers
also absorb and distribute the crash energy from the
driver and the front seat passenger to the structure
of the instrument panel. The seat belt tensioner
removes the slack from the driver side front seat belt
to provide further assurance that the driver is prop-
erly positioned and restrained for an airbag deploy-
ment.

DIAGNOSIS AND TESTING - SUPPLEMENTAL
RESTRAINT SYSTEM
Proper diagnosis and testing of the supplemental
restraint system components, the PCI data bus, the
data bus message inputs to and outputs from the
ElectroMechanical Instrument Cluster (EMIC), the
Airbag Control Module (ACM), or the Side Impact
Airbag Control Module (SIACM) as well as the
retrieval or erasure of a Diagnostic Trouble Code
(DTC) from the ACM or SIACM requires the use of a
DRBIIItscan tool. Refer to the appropriate diagnos-
tic information.
WARNING: ON VEHICLES EQUIPPED WITH AIR-
BAGS, DISABLE THE SUPPLEMENTAL RESTRAINT
SYSTEM BEFORE ATTEMPTING ANY STEERING
WHEEL, STEERING COLUMN, DRIVER AIRBAG,
PASSENGER AIRBAG, SEAT BELT TENSIONER,
FRONT IMPACT SENSORS, SIDE CURTAIN AIRBAG,
OR INSTRUMENT PANEL COMPONENT DIAGNOSIS
OR SERVICE. DISCONNECT AND ISOLATE THE
BATTERY NEGATIVE (GROUND) CABLE, THEN
WAIT TWO MINUTES FOR THE SYSTEM CAPACI-
TOR TO DISCHARGE BEFORE PERFORMING FUR-
THER DIAGNOSIS OR SERVICE. THIS IS THE ONLY
SURE WAY TO DISABLE THE SUPPLEMENTAL
RESTRAINT SYSTEM. FAILURE TO TAKE THE
PROPER PRECAUTIONS COULD RESULT IN ACCI-
DENTAL AIRBAG DEPLOYMENT AND POSSIBLE
PERSONAL INJURY.
STANDARD PROCEDURE
STANDARD PROCEDURE - HANDLING
NON-DEPLOYED SUPPLEMENTAL RESTRAINTS
At no time should any source of electricity be per-
mitted near the inflator on the back of a non-de-
ployed airbag or seat belt tensioner. When carrying a
non-deployed airbag, the trim cover or airbag cushion
side of the unit should be pointed away from the
body to minimize injury in the event of an accidental
deployment. If the airbag unit is placed on a bench or
any other surface, the trim cover or airbag cushion
side of the unit should be face up to minimize move-
ment in the event of an accidental deployment. When
handling a non-deployed seat belt tensioner, take
proper care to keep fingers out from under the
retractor cover and away from the seat belt webbing
where it exits from the retractor cover. In addition,
the supplemental restraint system should be dis-
armed whenever any steering wheel, steering col-
umn, seat belt tensioner, driver airbag, passenger
airbag, front impact sensor, side curtain airbag, or
instrument panel components require diagnosis or
service. Failure to observe this warning could result
in accidental airbag deployment and possible per-
sonal injury.
All damaged, faulty or non-deployed airbags and
seat belt tensioners which are replaced on vehicles
are to be handled and disposed of properly. If an air-
bag or seat belt tensioner unit is faulty or damaged
and non-deployed, refer to the Hazardous Substance
Control System for proper disposal. Dispose of all
non-deployed and deployed airbags and seat belt ten-
sioners in a manner consistent with state, provincial,
local and federal regulations.
SUPPLEMENTAL RESTRAINT STORAGE
Airbags and seat belt tensioners must be stored in
their original, special container until they are used
for service. Also, they must be stored in a clean, dry
environment; away from sources of extreme heat,
sparks, and high electrical energy. Always place or
store any airbag on a surface with its trim cover or
airbag cushion side facing up, to minimize movement
in case of an accidental deployment.
STANDARD PROCEDURE - SERVICE AFTER A
SUPPLEMENTAL RESTRAINT DEPLOYMENT
Any vehicle which is to be returned to use follow-
ing a supplemental restraint deployment, must have
the deployed restraints replaced. In addition, if the
driver airbag has been deployed, the clockspring
must be replaced. If the passenger airbag is
deployed, the passenger airbag door and both passen-
ger airbag mounting brackets must be replaced. If a
side curtain airbag has been deployed, the complete

PASSENGER AIRBAG
DESCRIPTION
The rearward facing surface of the injection
molded, thermoplastic passenger airbag door is the
most visible part of the passenger airbag (Fig. 23).
The passenger airbag door is located above the glove
box opening in front of the front seat passenger seat-
ing position on the instrument panel. The integral
upper mounting flange is secured with five screws
and the lower mounting flange with six screws to the
instrument panel structural support. The passenger
airbag door includes an integral air conditioning
panel outlet housing and an integral side window
demister outlet. An integral stamped metal bracket
that reinforces the upper airbag door mounting
flange is secured to the back of the door unit with
heat stakes. The upper airbag door fasteners and
mounting flange are concealed beneath the instru-
ment panel top cover, while the lower fasteners and
mounting flange are concealed beneath a bezel on the
instrument panel above the glove box opening.
Located behind the passenger airbag door within
the instrument panel is the passenger airbag unit
(Fig. 24). The passenger airbag unit used in this
model is a multistage, Next Generation-type that
complies with revised federal airbag standards to
deploy with less force than those used in some prior
models. The passenger airbag unit consists of a
molded, glass-filled nylon plastic housing, a molded
plastic inner airbag cushion cover, the airbag cush-
ion, and the airbag inflator. The airbag housing con-tains the airbag inflator, while the inner cover
contains the folded airbag cushion. The inner cover
completely encloses the airbag cushion and is perma-
nently retained to the housing. The passenger airbag
unit is secured by two screws on each side to two
stamped metal mounting brackets that are fastened
with screws to the instrument panel structural sup-
port. The airbag cushion is constructed of a coated
nylon fabric. The airbag inflator is a dual-initiator,
hybrid-type unit that is secured to and sealed within
the airbag housing. A short four-wire pigtail harness
with a keyed, yellow connector insulator connects the
two inflator initiators to the vehicle electrical system
through a dedicated take out and connector of the
instrument panel wire harness.
The passenger airbag cannot be repaired, and must
be replaced if deployed, faulty, or in any way dam-
aged. The passenger airbag door and the passenger
airbag mounting brackets are available for separate
service replacement.
OPERATION
The multistage passenger airbag is deployed by
electrical signals generated by the Airbag Control
Module (ACM) through the passenger airbag squib 1
and squib 2 circuits to the two initiators in the air-
bag inflator. By using two initiators, the airbag can
be deployed at multiple levels of force. The force level
is controlled by the ACM to suit the monitored
impact conditions by providing one of three delay
intervals between the electrical signals provided to
the two initiators. The longer the delay between
these signals, the less forcefully the airbag will
deploy.

(SKIS). Following are paragraphs that briefly
describe the operation of each of these two sub-
systems.
VEHICLE THEFT ALARM The Body Control Mod-
ule (BCM) is used on this model to control and inte-
grate many of the electronic functions and features
included in the Vehicle Theft Alarm (VTA). The BCM
receives hard wired inputs indicating the status of
the door ajar switches, the door cylinder lock
switches, the ignition switch, the tailgate ajar switch,
the tailgate cylinder lock switch, the flip-up glass
ajar switch, the power lock switches and, in vehicles
built for certain markets where it is required, the

VEHICLE THEFT SECURITY (Continued)

SECURED ACCESS METHOD
The Secured Access method applies to all vehicles.
This method requires the use of a DRBIIItscan tool.
This method will also require that you have access to
the unique four-digit PIN code that was assigned to
the original SKIM. The PIN codemustbe used to
enter the Secured Access Mode in the SKIM. This
PIN number may be obtained from the vehicle owner,
from the original vehicle invoice, or from the
DaimlerChrysler Customer Center. Refer to the
appropriate diagnostic information for the proper
Secured Access method programming procedures.
CUSTOMER LEARN METHOD
The Customer Learn feature is only available on
domestic vehicles, or those vehicles which have a
U.S. country code designator. This programming
method also requires access to at least two valid Sen-
try Keys. If two valid Sentry Keys are not available,
or if the vehicle does not have a U.S. country code
designator, the Secured Access Methodmustbe used
to program new or additional valid keys to the SKIM.
The Customer Learn programming method proce-
dures are as follows:
(1) Obtain the blank Sentry Key(s) that are to be
programmed as valid keys for the vehicle. Cut the
blank key(s) to match the ignition switch lock cylin-
der 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 switch 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 in the lock cylinder within fifteen seconds
of removing the first valid key.
(4) About ten seconds after the completion of Step
3, the SKIS indicator in the instrument cluster will
start to flash and a single audible chime tone will
sound to indicate that the system has entered the
Customer Learn programming mode.
(5) Within sixty seconds of entering the Customer
Learn programming 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 SKIS
indicator will stop flashing, stay on solid for three sec-
onds, then turn off to indicate that the blank Sentry
Key has been successfully programmed. The SKIS will
immediately exit the Customer Learn programmingmode and the vehicle may now be started using the
newly programmed valid Sentry Key.
Each of these steps must be repeated and com-
pleted in their entirety for each additional Sentry
Key that is to be programmed. If the above steps are
not completed in the given sequence, or within the
allotted time, the SKIS will exit the Customer Learn
programming mode and the programming will be
unsuccessful. The SKIS will also automatically exit
the Customer Learn programming mode if it sees a
non-blank Sentry Key transponder when it should
see a blank, if it has already programmed eight (8)
valid Sentry Keys, or if the ignition switch is turned
to the Off position for more than about fifty seconds.
NOTE: If an attempt is made to start the vehicle
while in the Customer Learn mode (SKIS indicator
flashing), the SKIS will respond as though the vehi-
cle were being started with an invalid key. In other
words, the engine will stall after about two seconds
of operation. No faults will be set.
NOTE: Once a Sentry Key has been programmed as
a valid key to a vehicle, it cannot be programmed
as a valid key for use on any other vehicle.
