GENERAL INFORMATION
Each vehicle is equipped with lamps used for illumi-
nating and indicating purposes. A circuit must have a
good ground to be complete. Circuit ground occurs
when the lamp socket makes contact with the metal
body. On vehicles with plastic lamps, a wire between
the socket and the body makes the grounds. When changing lamp bulbs, check the socket for
corrosion. If corrosion is present, clean contacts with a
wire brush and coat the inside of the socket with
Mopar tMulti-purpose Grease or equivalent.
CAUTION: Do not touch the glass of halogen bulbs
with fingers or any possibly oily surface, reduced
bulb life will result.

GENERAL INFORMATION
AA-BODY
The Illuminated Entry System (on AA Body) actu-
ates the interior courtesy and/or dome lamps (except
for the illuminated ignition switch) by lifting either
front door exterior handle. Lamp illumination is terminated 35 seconds ( 68
seconds later when battery voltage is normal), or by
turning the ignition switch to the run position,
whichever occurs first. When testing the system, all
vehicle doors must be closed to prevent the door jam
switches from activating the courtesy/dome lamps. Front door handle switches (Fig. 1), and the Illumi-
nated Entry Module (located behind and above the
glove box (Fig. 2) are used to control the system.
Depending on vehicle options, as many as six dif-
ferent electrical components/relays are located above
the glove box. The Illuminated Entry Module will be
the one mounted the closest to the outside of the in-
strument panel. The Module bracket is also used to
commonly mount the Power Door Lock Inhibitor Re-
lay, if equipped. Service procedures for door related components can
be found in Group 23, Body.

TEMPTING TO DIAGNOSE, REMOVE OR INSTALL
THE AIR BAG SYSTEM COMPONENTS, YOU MUST
FIRST DISCONNECT AND ISOLATE THE NEGATIVE
(GROUND) BATTERY CABLE. FAILURE TO DO SO
COULD RESULT IN ACCIDENTAL DEPLOYMENT
AND POSSIBLE PERSONAL INJURY. WHEN AN UNDEPLOYED AIR BAG ASSEMBLY
IS TO BE REMOVED FROM THE STEERING
WHEEL, DISCONNECT BATTERY GROUND CA-
BLE AND ISOLATE. ALLOW SYSTEM CAPACI-
TOR TO DISCHARGE FOR TWO MINUTES THEN
BEGIN AIR BAG SYSTEM COMPONENT RE-
MOVAL. Vehicles equipped with a Air Bag System must be
inspected every three years or 30,000 miles / 48,000
Km. To inspect system use Passive Restraint System
Diagnostic Procedures Manual. If the Air Bag Module Assembly is defective and
non-deployed, refer to Chrysler Motors current re-
turn list for proper handling procedures.
WARNING: REPLACE AIR BAG SYSTEM COMPO-
NENTS WITH CHRYSLER MOPAR TSPECIFIED RE-
PLACEMENT PARTS. SUBSTITUTE PARTS MAY
VISUALLY APPEAR INTERCHANGEABLE, BUT IN-
TERNAL DIFFERENCES MAY RESULT IN INFERIOR
OCCUPANT PROTECTION.
THE FASTENERS, SCREWS, AND BOLTS, ORIG-
INALLY USED FOR THE AIR BAG COMPO-
NENTS, HAVE SPECIAL COATINGS AND ARE
SPECIFICALLY DESIGNED FOR THE AIR BAG
SYSTEM. THEY MUST NEVER BE REPLACED
WITH ANY SUBSTITUTES. ANYTIME A NEW
FASTENER IS NEEDED, REPLACE WITH THE CORRECT FASTENERS PROVIDED IN THE SER-
VICE PACKAGE OR FASTENERS LISTED IN THE

GENERAL INFORMATION
AIR BAG MODULE
The air bag module is the most visible part of the
system (Fig 1). It contains the air bag cushion and
its supporting components. The air bag module con-
tains a housing to which the cushion and inflator are
attached and sealed.
The inflator assembly is mounted to the back of the
module housing. When supplied with the proper elec-
trical signal the inflator assembly will produce a gas
and discharges it directly into the cushion. A protec-
tive cover is fitted to the front of the air bag module
and forms a decorative cover in the center of the
steering wheel. The air bag module is mounted di-
rectly to the steering wheel.
Fig. 1 Air Bag Passive Restraint System
Ä RESTRAINT SYSTEMS 8M - 1

FRONT IMPACT SENSORS
The driver air bag system is a safety device de-
signed to reduce the risk of fatality or serious injury,
caused by a frontal impact of the vehicle. The impact sensors provide verification of the di-
rection and severity of the impact. Three impact sen-
sors are used. One is called a safing sensor. It is
located inside the diagnostic module which is
mounted on the floor pan, just forward of the center
console. The other two sensors are mounted on the
upper crossmember of the radiator closure panel on
the left and right side of the vehicle under the hood. The impact sensors are threshold sensitive switches
that complete an electrical circuit when an impact
provides a sufficient G force to close the switch. The
sensors are calibrated for the specific vehicle and re-
act to the severity and direction of the impact.
CLOCKSPRING
The clockspring is mounted on the steering column
behind the steering wheel, and is used to maintain a
continuous electrical circuit between the wiring har-
ness and the driver's air bag module. This assembly
consists of a flat ribbon-like electrically conductive
tape which winds and unwinds with the steering
wheel rotation.
DIAGNOSTIC MODULE
The Air Bag System Diagnostic Module (ASDM)
contains the safing sensor and energy reserve capac-
itor. The ASDM monitors the system to determine
the system readiness. The ASDM will store sufficient
energy to deploy the air bag for only two minutes af-
ter the battery is disconnected. If both front impact
sensors are open the air bag could be deployed up to
9.5 minutes after the battery is disconnected. The
ASDM contains on-board diagnostics, and will illumi-
nate the AIR BAG warning lamp in the cluster when
a fault occurs.
STORAGE
The air bag module must be stored in its original
special container until used for service. Additionally,
it must be stored in a clean, dry environment, away
from sources of extreme heat, sparks, and sources of
high electrical energy. Always place or store the
module on a surface with the trim cover facing up to
minimize movement in case of accidental deploy-
ment.
HANDLING LIVE MODULE
At no time should any source of electricity be per-
mitted near the inflator on the back of the module.
When carrying a live module, the trim cover should
be pointed away from the body to minimize injury in
the event of accidental deployment. In addition, if
the module is placed on a bench or other surface, the plastic trim cover should be face up to minimize
movement in case of accidental deployment. When handling a steering column with an air bag
module attached, never place the column on the floor
or other surface with the steering wheel or module
face down.
DEPLOYED MODULE
The vehicle interior may contain a very small
amount of sodium hydroxide powder, a byproduct of
air bag deployment. Since this powder can irritate
the skin, eyes, nose or throat, be sure to wear safety
glasses, rubber gloves and long sleeves during
cleanup (Fig. 2).
If you find that the cleanup is irritating your skin,
run cool water over the affected area. Also, if you ex-
perience nasal or throat irritation, exit the vehicle
for fresh air until the irritation ceases. If irritation
continues, see a physician.
CLEANUP PROCEDURE
Begin the cleanup by putting tape over the two air
bag exhaust vents (Fig. 3) so that no additional pow-
der will find its way into the vehicle interior. Then
remove the air bag and air bag module from the ve-
hicle. Use a vacuum cleaner to remove any residual pow-
der from the vehicle interior. Work from the outside
in so that you avoid kneeling or sitting in a un-
cleaned area. Be sure to vacuum the heater and A/C outlets as
well (Fig. 4). In fact it's a good idea to run the blower
on low and to vacuum up any powder expelled from
the plenum. You may need to vacuum the interior of
the car a second time to recover all of the powder. Place the deployed bag and module in your auto-
motive scrap.

SERVICE OF DEPLOYED AIR BAG MODULE
After an air bag has been deployed, the air bag
module and clockspring must be replaced because
they cannot be reused. Other air bag system compo-
nents are replaced if damaged.
SCHEDULED MAINTENANCE INSPECTION
Vehicles equipped with a Air Bag System must be
inspected every three years or 30,000 miles / 48,000
Km. The following items should be inspected. (1) Inspect components for damage or deteriora-
tion. (a) If the air bag module housing shows signs of
physical damage or abuse, replace the module. (b) Check that both front impact sensors are
properly installed to the upper crossmember of the
radiator closure panel. Repair as required.
(2) Check the air bag warning lamp for proper op-
eration as follows: (a) Turn ignition switch to the ON position, the
air bag warning lamp should light. If not, test the system using the DRB II and Passive Restraint
System Diagnostic Procedures Manual. Repair as
required.
(b) The air bag warning lamp lights, but fails to go
out after ten seconds. Test the system using the DRB
II and Passive Restraint System Diagnostic Proce-
dures Manual. Repair as required. (c) Erasing of fault codes is not required.
AIR BAG SYSTEM CHECK
WARNING: BEFORE BEGINNING ANY AIR BAG SYS-
TEM CHECK PROCEDURES, REMOVE AND ISOLATE
THE BATTERY NEGATIVE (-) CABLE (GROUND)
FROM THE VEHICLE BATTERY. THIS IS THE ONLY
SURE WAY TO DISABLE THE AIR BAG SYSTEM.
FAILURE TO DO THIS COULD RESULT IN ACCIDEN-
TAL AIR BAG DEPLOYMENT AND POSSIBLE PER-
SONAL INJURY.
WHEN AN UNDEPLOYED AIR BAG ASSEMBLY IS
TO BE REMOVED FROM THE STEERING WHEEL,
DISCONNECT BATTERY GROUND CABLE AND
ISOLATE. ALLOW SYSTEM CAPACITOR TO DIS-
CHARGE FOR TWO MINUTES, THEN BEGIN AIR
BAG REMOVAL. (1) Disconnect the battery negative cable and iso-
late. (2) Remove forward console or cover as necessary.
(3) Connect DRB II to ASDM diagnostic 6-way con-
nector, located at right side of module. (4) Turn the ignition key to ON position. Exit vehicle
with DRB II. Use the latest version of the proper
cartridge. (5) After checking that no one is inside the vehicle,
connect the negative battery cable. (6) Using the DRB II, read and record active fault
data. (7) Read and record any stored faults.
(8) Refer to the Passive Restraint Diagnostic Test
Manual if any faults are found in steps 6 and 7. (9) Erase stored faults if there are no active fault
codes. If problems remain, fault codes will not erase. (10) With the ignition key in the ON position, make
sure no one is in the vehicle. (11) From the passenger side of vehicle, turn the
ignition key to OFF then ON and observe the instru-
ment cluster air bag lamp. It should go on for 6 to 8
seconds, then go out; indicating system is functioning
normally. If air bag warning lamp either fails to light,
blinks on and off or goes on and stays on, there is
a system malfunction. Refer to the Passive Re-
straint Diagnostic Test Manual to diagnose the
problem.
