DESCRIPTION
A dual front airbag system is standard factory-in-
stalled safety equipment on this model. The airbag
system is a passive, inflatable, Supplemental
Restraint System (SRS) and vehicles with this equip-
ment can be readily identified by the ªSRS - AIR-
BAGº 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. 1). Vehicles with the airbag sys-
tem can also be identified by the airbag indicator,which will illuminate in the instrument cluster for
about seven seconds as a bulb test each time the
ignition switch is turned to the On position.
The dual front airbag system consists of the follow-
ing major components, which are described in further
detail elsewhere in this service manual:
²Airbag Control Module- The Airbag Control
Module (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.
BR/BERESTRAINTS 8O - 1

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 molded plastic structural unit secured to the
back side of and integral to the instrument panel
steering column opening cover.
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 Airbag On/Off Switch- The pas-
senger airbag on/off switch is located in a dedicated
opening in the upper right corner of the instrument
panel cluster bezel, to the right of the center panel
outlets of the climate control system.
²Passenger Knee Blocker- The passenger knee
blocker is a structural reinforcement that is integral
to and concealed within the glove box door.
The ACM and the EMIC each contain a central
processing unit and programming that allow them to
communicate with each other using the Chrysler Col-
lision Detection (CCD) data bus network. This
method of communication is used for control of the
airbag indicator on all models. (Refer to 8 - ELEC-
TRICAL/ELECTRONIC CONTROL MODULES/
COMMUNICATION - DESCRIPTION).
Hard wired circuitry connects the airbag system
components to each other through the electrical sys-
tem of the vehicle. These hard wired circuits are
integral to several wire harnesses, which are routed
throughout the vehicle and retained by many differ-
ent methods. These circuits may be connected to each
other, to the vehicle electrical system, and to the air-
bag system components through the use of a combi-
nation of soldered splices, splice block connectors,and many different types of wire harness terminal
connectors and insulators. 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
The airbag system is referred to as a supplemental
restraint system because it was designed and is
intended to enhance the protection for the front seat
occupants of the vehicleonlywhen used in conjunc-
tion with the seat belts. It is referred to as a passive
system because the vehicle occupants are not
required to do anything to make it work. The pri-
mary passenger restraints in this or any other vehi-
cle are the standard equipment factory-installed seat
belts. Seat belts are referred to as an active restraint
because the vehicle occupants are required to physi-
cally fasten and properly adjust these restraints in
order to benefit from them. The vehicle occupants
must be wearing their seat belts in order to obtain
the maximum safety benefit from the factory-in-
stalled airbag system.
The airbag system electrical circuits are continu-
ously monitored and controlled by a microprocessor
and software contained within the Airbag Control
Module (ACM). An airbag indicator in the ElectroMe-
chanical Instrument Cluster (EMIC) lights for about
seven seconds as a bulb test each time the ignition
switch is turned to the On or Start positions. Follow-
ing the bulb test, the airbag indicator is turned on or
off by the ACM to indicate the status of the airbag
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 airbag system electrical cir-
cuits. Such a problem may cause the airbags not to
deploy when required, or to deploy when not
required.
The clockspring on the top of the steering column
allows a continuous electrical circuit to be main-
tained between the stationary steering column and
the driver airbag inflator, which rotates with the
steering wheel. The passenger airbag on/off switch
allows the passenger side airbag to be disabled when
circumstances necessitate that a child, or an adult
with certain medical conditions be placed in the front
passenger seating position. Refer to the owner's man-
ual in the vehicle glove box for specific recommenda-
tions concerning the specific circumstances where the
passenger airbag on/off switch should be used to dis-
able the passenger airbag.

RESTRAINTS (Continued)

Deployment of the airbags depends upon the angle
and severity of the impact. The airbag system is
designed to deploy upon a frontal impact within a
thirty degree angle from either side of the vehicle
center line. 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 airbag system impact sensor, which is
integral to the ACM. When a frontal impact is severe
enough, the microprocessor in the ACM signals the
inflator units of both airbag modules to deploy the
airbags. During a frontal vehicle impact, the knee
blockers work in concert with properly fastened 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.
Typically, the driver and front seat passenger recall
more about the events preceding and following a col-
lision than they have of the airbag deployment itself.
This is because the airbag deployment and deflation
occur so rapidly. In a typical 48 kilometer-per-hour
(30 mile-per-hour) barrier impact, from the moment
of impact until both airbags are fully inflated takes
about 40 milliseconds. Within one to two seconds
from the moment of impact, both airbags are almost
entirely deflated. The times cited for these events are
approximations, which apply only to a barrier impact
at the given speed. Actual times will vary somewhat,
depending upon the vehicle speed, impact angle,
severity of the impact, and the type of collision.
When the ACM monitors a problem in any of the
airbag system circuits or components, it stores a
fault code or Diagnostic Trouble Code (DTC) in its
memory circuit and sends an electronic message to
the EMIC to turn on the airbag indicator. Proper
testing of the airbag system components, the
Chrysler Collision Detection (CCD) data bus, the
data bus message inputs to and outputs from the
EMIC or the ACM, as well as the retrieval or erasure
of a DTC from the ACM requires the use of a
DRBIIItscan tool. Refer to the appropriate diagnos-
tic information.
See the owner's manual in the vehicle glove box for
more information on the features, use and operation
of all of the factory-installed passenger restraints,
including the airbag system.

DIAGNOSIS AND TESTING - AIRBAG SYSTEM
Proper diagnosis and testing of the airbag system
components, the PCI data bus, the data bus message
inputs to and outputs from the ElectroMechanical
Instrument Cluster (EMIC) or the Airbag Control
Module (ACM), as well as the retrieval or erasure of
a Diagnostic Trouble Code (DTC) from the ACM
requires the use of a DRBIIItscan tool. Refer to the
appropriate diagnostic information.
WARNING: ON VEHICLES EQUIPPED WITH AIR-
BAGS, DISABLE THE AIRBAG SYSTEM BEFORE
ATTEMPTING ANY STEERING WHEEL, STEERING
COLUMN, OR INSTRUMENT PANEL COMPONENT
DIAGNOSIS OR SERVICE. DISCONNECT AND ISO-
LATE THE BATTERY NEGATIVE (GROUND) CABLE,
THEN WAIT TWO MINUTES FOR THE AIRBAG SYS-
TEM CAPACITOR TO DISCHARGE BEFORE PER-
FORMING FURTHER DIAGNOSIS OR SERVICE. THIS
IS THE ONLY SURE WAY TO DISABLE THE AIRBAG
SYSTEM. FAILURE TO TAKE THE PROPER PRE-
CAUTIONS COULD RESULT IN ACCIDENTAL AIR-
BAG DEPLOYMENT AND POSSIBLE PERSONAL
INJURY.
STANDARD PROCEDURE - HANDLING
NON-DEPLOYED AIRBAGS
At no time should any source of electricity be per-
mitted near the inflator on the back of a non-de-
ployed airbag. 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 sur-
face, the trim cover or airbag cushion side of the unit
should be face up to minimize movement in the event
of an accidental deployment. In addition, the airbag
system should be disarmed whenever any steering
wheel, steering column, or instrument panel compo-
nents require diagnosis or service. Failure to observe
this warning could result in accidental airbag deploy-
ment and possible personal injury.
All damaged or faulty and non-deployed driver or
passenger airbags which are replaced on vehicles are
to be returned. If an airbag unit is faulty or damaged
and non-deployed, refer to the parts return list in the
current DaimlerChrysler Corporation Warranty Poli-
cies and Procedures manual for the proper handling
and disposal procedures.
AIRBAG STORAGE
An airbag must be stored in its original, special
container until it is used for service. Also, it must be
stored in a clean, dry environment; away from
sources of extreme heat, sparks, and high electricalenergy. 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 AN
AIRBAG DEPLOYMENT
Any vehicle which is to be returned to use follow-
ing an airbag deployment, must have both airbags,
the driver airbag trim cover, the clockspring, and the
steering column assembly replaced. These compo-
nents are not intended for reuse and will be damaged
or weakened as a result of an airbag deployment,
which may or may not be obvious during a visual
inspection. Other vehicle components should be
closely inspected, but are to be replaced only as
required by the extent of the visible damage
incurred.
CLEANUP PROCEDURE
Following an airbag deployment, the vehicle inte-
rior will contain a powdery residue. This residue con-
sists primarily of harmless particulate by-products of
the small pyrotechnic charge used to initiate the pro-
pellant used to deploy the airbags. However, this res-
idue may also contain traces of sodium hydroxide
powder, a chemical by-product of the propellant
material that is used to generate the nitrogen gas
that inflates the airbag. Since sodium hydroxide pow-
der can irritate the skin, eyes, nose, or throat, be
sure to wear safety glasses, rubber gloves, and a
long-sleeved shirt during cleanup (Fig. 2).

(9) Turn the ignition switch to the Off position for
about fifteen seconds, and then back to the On posi-
tion. Observe the airbag indicator in the instrument
cluster. It should light for six to eight seconds, and
then go out. This indicates that the airbag system is
functioning normally and that the repairs are com-
plete. If the airbag indicator fails to light, or lights
and stays on, there is still an active airbag system
fault or malfunction. Refer to the appropriate diag-
nostic information to diagnose the problem.
SPECIAL TOOLS
SPECIAL TOOLS - AIRBAG SYSTEM
AIRBAG CONTROL MODULE
DESCRIPTION
The Airbag Control Module (ACM) is concealed
underneath the plastic ACM trim cover (automatic
transmission) or center console (manual transmis-
sion), directly below the instrument panel in the pas-
senger compartment of the vehicle. The ACM is
secured with screws to a mounting bracket located
under the instrument panel center support bracket
on the floor panel transmission tunnel. The ACM
contains an electronic microprocessor, an electronic
impact sensor, an electromechanical safing sensor,
and an energy storage capacitor. The ACM is con-
nected to the vehicle electrical system through a take
out and connector of the instrument panel wire har-
ness.
The ACM cannot be repaired or adjusted and, if
damaged or faulty, it must be replaced.
OPERATION
The microprocessor in the ACM contains the airbag
system logic circuits, and it monitors and controls all
of the airbag system components. The ACM also uses
On-Board Diagnostics (OBD) and can communicate
with other electronic modules in the vehicle as well
as with the DRBIIItscan tool using the Chrysler
Collision Detection (CCD) data bus network. This
method of communication is used for control of the
airbag indicator in the ElectroMechanical InstrumentCluster (EMIC) and for airbag system diagnosis and
testing through the 16-way data link connector
located on the lower left edge of the instrument
panel. (Refer to 8 - ELECTRICAL/ELECTRONIC
CONTROL MODULES/COMMUNICATION - OPER-
ATION). The ACM microprocessor continuously mon-
itors all of the airbag system electrical circuits to
determine the system readiness. If the ACM detects
a monitored system fault, it sets an active Diagnostic
Trouble Code (DTC) and sends messages to the
EMIC over the CCD data bus to turn on the airbag
indicator. (Refer to 8 - ELECTRICAL/INSTRUMENT
CLUSTER/AIRBAG INDICATOR - OPERATION). If
the airbag system fault is still present when the igni-
tion switch is turned to the Off position, the DTC is
stored in memory by the ACM. However, if a fault
does not recur for a number of ignition cycles, the
ACM will automatically erase the stored DTC.
The ACM receives battery current through two cir-
cuits, on a fused ignition switch output (run) circuit
through a fuse in the Junction Block (JB), and on a
fused ignition switch output (start-run) circuit
through a second fuse in the JB. The ACM is
grounded through a ground circuit and take out of
the instrument panel wire harness. This take out has
a single eyelet terminal connector secured by a nut to
a ground stud located on the forward extension of the
left front fender wheel housing in the engine com-
partment. Therefore, the ACM is operational when-
ever the ignition switch is in the Start or On
positions. The ACM also contains an energy-storage
capacitor. When the ignition switch is in the Start or
On positions, this capacitor is continually being
charged with enough electrical energy to deploy the
airbags for up to one second following a battery dis-
connect or failure. The purpose of the capacitor is to
provide backup airbag system protection in case
there is a loss of battery current supply to the ACM
during an impact. The capacitor is only serviced as a
unit with the ACM.
Two sensors are contained within the ACM, an
electronic impact sensor and a safing sensor. The
electronic impact sensor is an accelerometer that
senses the rate of vehicle deceleration, which pro-
vides verification of the direction and severity of an
impact. A pre-programmed decision algorithm in the
ACM microprocessor determines when the decelera-
tion rate as signaled by the impact sensor indicates
an impact that is severe enough to require airbag
system protection. When the programmed conditions
are met, the ACM sends an electrical signal to deploy
the airbags. The safing sensor is an electromechani-
cal sensor within the ACM that is connected in series
between the ACM microprocessor airbag deployment
circuit and the airbags. The safing sensor is a nor-
mally open switch that is used to verify or confirm

CLOCKSPRING
DESCRIPTION
The clockspring assembly is secured with two inte-
gral plastic latches onto the steering column lock
housing near the top of the steering column, behind
the steering wheel. The clockspring consists of a flat,
round molded plastic case with a stubby tail that
hangs below the steering column and contains a con-
nector receptacle and a long pigtail wire with connec-
tor that face toward the instrument panel. Within
the plastic housing is a spool-like molded plastic
rotor with a large exposed hub. The upper surface of
the rotor hub has a large center hole, two large flats,
two auto-locking tabs, and three short pigtail wires
with connectors that face toward the steering wheel.
The lower surface of the rotor hub has two integral
turn signal cancelling cam lobes. Within the plastic
case and wound around the rotor spool is a long rib-
bon-like tape that consists of several thin copper wire
leads sandwiched between two thin plastic mem-
branes. The outer end of the tape terminates at the
connector receptacle and pigtail wire that face the
instrument panel, while the inner end of the tape
terminates at the pigtail wires on the hub of the
clockspring rotor that face the steering wheel.
Service replacement clocksprings are shipped pre-
centered and with a piece of tape covering the
engaged auto-locking tabs. The auto-locking tabs
secure the centered clockspring rotor to the clock-
spring case during shipment, but these tabs are auto-
matically disengaged once the clockspring is installed
on the steering column. (Refer to 8 - ELECTRICAL/
RESTRAINTS/CLOCKSPRING - STANDARD PRO-
CEDURE - CLOCKSPRING CENTERING).
The clockspring cannot be repaired. If the clock-
spring is faulty, damaged, or if the driver airbag has
been deployed, the clockspring must be replaced.
OPERATION
The clockspring is a mechanical electrical circuit
component that is used to provide continuous electri-
cal continuity between the fixed instrument panel
wire harness and the electrical components mountedon or in the rotating steering wheel. On this model
the rotating electrical components include the driver
airbag, the horn switch, the speed control switches,
and the remote radio switches if the vehicle is so
equipped. The clockspring case is positioned and
secured to the upper steering column lock housing by
two integral plastic latches. The connector receptacle
on the tail of the fixed clockspring housing connect
the clockspring to the vehicle electrical system
through a take out with connector from the instru-
ment panel wire harness. The lower clockspring pig-
tail on the tail of the clockspring housing connect the
clockspring driver airbag circuits to a separate take
out and connector of the instrument panel wire har-
ness located near the lower instrument panel rein-
forcement, below the steering column. The
clockspring rotor is movable and is keyed to the hub
of the steering wheel by two large flats that are
molded into the rotor hub. The two lobes on the
lower surface of the clockspring rotor hub contact a
turn signal cancel actuator of the multi-function
switch to provide automatic turn signal cancellation.
The pigtail wires on the upper surface of the clock-
spring connect the clockspring to the horn switch, the
two speed control switches, and the remote radio
switches on vehicles that are so equipped.
Like the clockspring in a timepiece, the clockspring
tape has travel limits and can be damaged by being
wound too tightly during full stop-to-stop steering
wheel rotation. To prevent this from occurring, the
clockspring must be centered when it is installed on
the steering column. Centering the clockspring
indexes the clockspring spool to the movable steering
components so that the tape can operate within its
designed travel limits. However, if the clockspring is
removed from the steering column or if the steering
shaft is disconnected from the steering gear, the
clockspring spool can change position relative to the
movable steering components and must be re-cen-
tered following completion of the service or the tape
may be damaged. Service replacement clocksprings
are shipped pre-centered and with the auto-locking
tabs engaged. A piece of tape covers the auto-locking
tabs to discourage tampering. These auto-locking
tabs should not be disengaged until the clockspring
