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.

(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

GENERAL INFORMATION
WARNING: ON VEHICLES EQUIPPED WITH AN AIR
BAG REFER TO THE AIR BAG PORTION OF THIS
SECTION FOR STEERING WHEEL OR SWITCH RE-
MOVAL AND INSTALLATION PROCEDURES.
BUZZER SYSTEM
The seat belt warning system uses both visual and
audible signals. A combined seat belt and key warn-
ing buzzer with a red light on the instrument panel. The system will always illuminate the seat belt
warning lamp for four to eight seconds when the ig-
nition switch is turned to the ON position. Also, only
if the driver does not fasten his seat belt, the buzzer
will sound during the same time interval. Passenger
belts are not connected to the system. A timed buzzer-relay is used to operate the system
for the time period. It consists of a time delay mech-
anism and buzzer assembly. Only the driver's seat
belt buckle has a switch that is connected to the sys-
tem.
CHIME WARNING/REMINDER SYSTEM
The chime warning/reminder system is similar in
operation to the buzzer system except for a more
pleasant sounding tone. This chime type tone sounds
for all three warning/reminder conditions; namely
headlamps left on, keys left in ignition and fasten
seat belt.
TIMED BUZZER-RELAY TESTÐAP BODY
PREPARATION
(1) Remove timed buzzer-relay (Fig. 1).
(2) Connect one end of a jumper wire to a 12 volt
supply. (3) Connect a test lamp equipped with a number
194 lamp or equivalent, between terminal number 3
of relay and ground. (4) Ground terminals 2 and 5 of relay.
TEST
(1) Connect 12 volt jumper wire to terminal num-
ber 4 of timed buzzer-relay, look at test lamp and lis-
ten for buzzer. (2) Test lamp should come on and buzzer should
sound for four to eight seconds and then both should
go off; if not, replace timed buzzer-relay. (3) If operation is okay, check all wiring in vehicle
for opens, shorts, or poor connections.
SEAT BELT BUCKLE SWITCH TEST BUZZER
SYSTEM
Test timed buzzer-relay. If it checks OK, check the
wiring between seat belt buckle and ground. The
wire that goes to terminal 5 of relay from buckle
switch, refer to Fig. 2 and 3. If they check out okay,
replace buckle switch.
CHIME WARNING/REMINDER SYSTEM TEST
FASTEN SEAT BELTS
To test the fasten seat belts function, turn the ig-
nition switch to the ON position with the driver's
seat belt unbuckled. The seat belt warning lamp
should light for four to eight seconds and the tone
should sound three to five times.

HEADLAMPS LEFT ON
To test the headlamps left on function, turn head-
lamps on with drivers door open. Chime should
sound until headlamps are turned off or drivers door
is closed.
KEY LEFT IN IGNITION
To test the key left in ignition function, insert key
into the ignition and open drivers door. Chime
should sound until key is removed from ignition or
drivers door is closed.
