DIAGNOSIS AND TESTING - AIRBAG SYSTEM
Proper diagnosis and testing of the airbag system
components, the Chrysler Collision Detection (CCD)
data bus, the data bus message inputs to and out-
puts 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 diagnos-
tic information.

STANDARD PROCEDURE
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, faulty, or non-deployed airbags which
are replaced on vehicles are to handled and disposed
of properly. If an airbag unit is faulty or damagedand non-deployed, refer to the Hazardous Substance
Control System for proper disposal. Dispose of all
non-deployed and deployed airbags in a manner con-
sistent with state, provincial, local and federal regu-
lations.
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 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 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).
WARNING: IF YOU EXPERIENCE SKIN IRRITATION
DURING CLEANUP, RUN COOL WATER OVER THE
AFFECTED AREA. ALSO, IF YOU EXPERIENCE
IRRITATION OF THE NOSE OR THROAT, EXIT THE
VEHICLE FOR FRESH AIR UNTIL THE IRRITATION
CEASES. IF IRRITATION CONTINUES, SEE A PHYSI-
CIAN.
Begin the cleanup by removing both airbags from
the vehicle. Refer to the appropriate service removal
procedures.

CAUTION: All damaged, faulty, or non-deployed air-
bags which are replaced on vehicles are to handled
and disposed of properly. If an airbag unit is faulty
or damaged and non-deployed, refer to the Hazard-
ous Substance Control System for proper disposal.
Dispose of all non-deployed and deployed airbags
in a manner consistent with state, provincial, local
and federal regulations.
Next, use a vacuum cleaner to remove any residual
powder from the vehicle interior. Clean from outside
the vehicle and work your way inside, so that you
avoid kneeling or sitting on a non-cleaned area. Be
certain to vacuum the heater and air conditioning
outlets as well (Fig. 3). Run the heater and air con-
ditioner blower on the lowest speed setting and vac-
uum any powder expelled from the outlets. You may
need to vacuum the interior of the vehicle a second
time to recover all of the powder.
STANDARD PROCEDURE - VERIFICATION TEST
The following procedure should be performed using
a DRBIIItscan tool to verify proper airbag system
operation following the service or replacement of any
airbag system component.

(1) During the following test, the battery negative
cable remains disconnected and isolated, as it was
during the airbag component removal and installa-
tion procedures.
(2) Be certain that the DRBIIItscan tool contains
the latest version of the proper DRBIIItsoftware.
Connect the DRBIIItto the 16-way Data Link Con-
nector (DLC). The DLC is located on the driver side
lower edge of the instrument panel, outboard of the
steering column (Fig. 4).
(3) Turn the ignition switch to the On position and
exit the vehicle with the DRBIIIt.
(4) Check to be certain that nobody is in the vehi-
cle, then reconnect the battery negative cable.
(5) Using the DRBIIIt, read and record the active
(current) Diagnostic Trouble Code (DTC) data.
(6) Next, use the DRBIIItto read and record any
stored (historical) DTC data.
(7) If any DTC is found in Step 5 or Step 6, refer
to the appropriate diagnostic information.
(8) Use the DRBIIItto erase the stored DTC data.
If any problems remain, the stored DTC data will not
erase. Refer to the appropriate diagnostic informa-
tion to diagnose any stored DTC that will not erase.
If the stored DTC information is successfully erased,
go to Step 9.
(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

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 stamped steel mounting
bracket located under the instrument panel center
support bracket on the floor panel transmission tun-
nel. The ACM contains an electronic microprocessor,
an electronic impact sensor, an electromechanical saf-
ing sensor, and an energy storage capacitor. TheACM is connected to the vehicle electrical system
through a take out and connector of the instrument
panel wire harness.
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 Instrument
Cluster (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.

PASSENGER AIRBAG ON/OFF
SWITCH
DESCRIPTION
The passenger airbag on-off switch is standard
equipment on this model when it is not equipped
with a full size rear seat. This switch is a single pole,
single throw switch with a single integral red Light-
Emitting Diode (LED), and a non-coded key cylinder-
type actuator. The switch is located in the upper
right corner of instrument panel cluster bezel, near
the center of instrument panel to make the Off indi-
cator visible to all front seat occupants. When the
BR/BERESTRAINTS 8O - 23
PASSENGER AIRBAG (Continued)

switch is in its installed position, the only compo-
nents visible through the dedicated opening of the
cluster bezel are the switch face plate and nomencla-
ture, the key cylinder actuator, and a small round
lens with the text9Off9imprinted on it. The ªOnº
position of the switch is designated by text imprinted
upon the face plate of the switch, but is not illumi-
nated. The remainder of the switch is concealed
behind the switch face plate and the instrument
panel cluster bezel.
The passenger airbag on-off switch housing is con-
structed of molded plastic and has three integral
mounting tabs. These mounting tabs are used to
secure the switch to the back of the molded plastic
switch face plate with three small screws. The
molded plastic face plate also has three integral
mounting tabs that are used to secure the switch and
face plate unit to the instrument panel carrier with
three additional screws. Two short pigtail wires with
molded plastic connector insulators exit the back of
the switch housing and connect the switch to the
vehicle electrical system through two dedicated take
outs of the instrument panel wire harness. The har-
ness take outs are equipped with molded plastic con-
nector insulators that are keyed and latched to
ensure proper and secure switch electrical connec-
tions. The passenger airbag on/off switch cannot be
adjusted or repaired and, if faulty or damaged, the
switch must be replaced.
OPERATION
The passenger airbag on/off switch allows the cus-
tomer to turn the passenger airbag function On or
Off to accommodate certain uses of the right front
seating position where airbag protection may not be
desired. See the owner's manual in the vehicle glove
box for specific recommendations on when to enable
or disable the passenger airbag. The Off indicator of
the switch will be illuminated whenever the switch is
turned to the Off position. The ignition key is the
only key or object that should ever be inserted into
the switch. The on/off switch requires only a partial
key insertion to fully depress a spring-loaded locking
plunger. The spring-loaded locking plunger prevents
the user from leaving the key in the switch. The key
will be automatically ejected when force is not
applied. To actuate the passenger side airbag on/off
switch, insert the ignition key into the switch key
actuator far enough to fully depress the plunger and
rotate to the desired switch position. When the
switch key actuator is rotated to its clockwise stop
(the key actuator slot will be aligned with the Off
indicator lamp), the Off indicator is illuminated and
the passenger airbag is disabled. When the switch is
rotated to its counterclockwise stop (the key actuator
slot will be in a vertical position), the Off indicatorwill be extinguished and the passenger airbag is
enabled.
The passenger airbag on/off switch is connected in
series between the Airbag Control Module (ACM) and
the passenger airbag inflator unit. When the switch
is in the On position, the switch connects the ACM
directly to the passenger airbag inflator. When the
switch is in the Off position it interrupts the inflator
circuits, but replaces the normal resistance in these
circuits with an internal resistor. Thus, the ACM is
unable to distinguish the mode of the switch and still
sends an electrical signal as though it were deploying
the passenger airbag when it detects a sufficient
impact. However, the switch position should not be
changed while the ignition switch is in the On posi-
tion, as the ACM may detect a fault, record a Diag-
nostic Trouble Code (DTC), and illuminate the Airbag
indicator in response to a momentary open it senses
in the passenger airbag inflator circuits as the on/off
switch changes states.

SEAT BELT SWITCH
DESCRIPTION
The seat belt switch is a small, normally closed,
single pole, single throw, leaf contact, momentary
switch. Only one seat belt switch is installed in the
vehicle, and it is integral to the buckle of the driver
seat belt buckle-half, located near the inboard side of
the driver side front seating position. The seat belt
switch is connected to the vehicle electrical system
through a two-wire pigtail wire and connector on the
seat belt buckle-half, which is connected to a wire
harness connector and take out of the body wire har-
ness.
The seat belt switch cannot be adjusted or repaired
and, if faulty or damaged, the entire driver seat belt
buckle-half 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).
When the driver side seat belt tip-half is inserted in
the seat belt buckle, the switch opens the path to
ground; and, when the driver side seat belt tip-half is
removed from the seat belt buckle, the switch closes
the ground path. The switch is actuated by the latch
mechanism within the seat belt buckle. The EMIC
monitors the driver seat belt switch status, then con-
trols the seatbelt indicator and sends hard wired
chime requests to the Central Timer Module (CTM)
based upon that input.
The seat belt switch receives ground through its
pigtail wire connection to the body wire harness from
another take out of the body wire harness. An eyelet
terminal connector on that ground take out issecured under a nut to a ground stud on the left
lower B-pillar (standard cab models) or the left lower
cowl side inner panel (club cab and quad cab models).
The seat belt switch is connected in series between
ground and the seat belt switch sense input of the
EMIC.
DIAGNOSIS AND TESTING - SEAT BELT
SWITCH
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.

the seat belt switch from the seat belt switch pigtail
wire connector located near the floor panel under the
driver side front seat cushion. Check for continuity
between the seat belt switch sense circuit and the
ground circuit cavities in the seat belt switch pigtail
wire connector. There should be continuity with the
driver side seat belt tip-half and buckle-half unfas-
tened, and no continuity with tip-half and buckle-half
fastened. If OK, go to Step 2. If not OK, replace the
faulty driver side seat belt buckle-half unit.
(2) Check for continuity between the ground cir-
cuit cavity in the body wire harness connector for the
seat belt switch and a good ground. There should be
continuity. If OK, go to Step 3. If not OK, repair the
