5. Remove passenger air bag assembly from vehicle.
Refer to “Passenger Air Bag Assembly Removal ” in
this Section 9J–3.
6. Clear a space on the ground approximately 183 cm
(six feet) in clearance where the fixture with attached
air bag assembly is to be placed for deployment. A
paved outdoor location where there is no activity is
preferred. If an outdoor location is not available, a
space on the shop floor where is no activity and
sufficient ventilation is recommended. Ensure that no
loose or flammable objects are within the deployment
area.
7. Place the 5–8840–2420–0 on the bench vice. This is
necessary to provide sufficient stabilization of the
fixture during deployment.
8. Attach the passenger air bag assembly in the
5–8840–2420–0. An air bag assembly must be
mounted such that the bag will deploy upward.
SECURELY HAND–TIGHTEN ALL FASTENERS
PRIOR TO DEPLOYMENT.

9. Stretch the SRS Deployment Harness and pigtail
adapter from the air bag assembly to its full length.
10. Place a power source near the shorted end of the
SRS deployment harness. (Recommended
application: 12 volts minimum, 2 amps minimum. A
vehicle battery is suggested.)
11. Connect the air bag assembly to the pigtail adapter on
the SRS deployment harness. The SRS Deployment
Harness shall remain shorted and not be connected
to a power source until the air bag is to be deployed.
The air bag assembly will immediately deploy the air
bag when a power source is connected to it.
NOTE: Ensure that the pigtail adapter is firmly seated into
the air bag assembly connector. Failure to fully seat the
connectors may leave the shorting bar located in the air
bag assembly connector functioning (shorting the
deployment circuit) and may result in nondeployment of
the air bag assembly.
12. Verify that the area around the passenger air bag
assembly is clear of all people and loose or flammable
objects.13. Verify that the passenger air bag assembly is firmly
and properly in 5–8840–2420–0.
14. Notify all people in the immediate area of your
intention to deploy the passenger air bag assembly.
The deployment will be accompanied by a substantial
noise which may startle the uninformed.
15. Separate the two banana plugs on the SRS
deployment harness.
NOTE: When air bag deploys, the rapid gas expansion
will create a substantial noise. Notify all people in the
immediate area that you intend to deploy the air bag
assembly.
WARNING: DEPLOYMENT HARNESS SHALL
REMAIN SHORTED AND NOT BE CONNECTED TO A
POWER SOURCE UNTIL THE AIR BAG IS TO BE
DEPLOYED. THE AIR BAG ASSEMBLY WILL
IMMEDIATELY DEPLOY THE AIR BAG WHEN A
POWER SOURCE IS CONNECTED TO IT.
CONNECTING THE DEPLOYMENT HARNESS TO
THE POWER SOURCE SHOULD ALWAYS BE THE
LAST STEP IN THE AIR BAG ASSEMBLY
DEPLOYMENT PROCEDURE. FAILURE TO FOLLOW
PROCEDURES IN THE ORDER LISTED MAY RESULT
IN PERSONAL INJURY.
16. Connect the SRS deployment harness wires to the
power source to immediately deploy the air bag
assembly. Recommended application : 12 volts
minimum, 2 amps minimum. A vehicle battery is
suggested.
17. Disconnect the SRS deployment harness from the
power source.
18. Short the two SRS deployment harness leads
together by fully seating one banana plug into the
other.
19. In the unlikely event that the passenger air bag
assembly did not deploy after following these
procedures, proceed immediately with Steps 24
through 26. If the passenger air bag assembly
deployed as intended, proceed with Steps 20 through
23.
20. Put on a pair of shop gloves and safety glasses to
protect your hands and eyes from possible irritation
and heat when handling the deployed air bag
assembly.
After the air bag assembly has been deployed, the
surface of the air bag may contain a powdery residue.
Th is p ow de r con sis ts prim a r ily of c or n sta r ch ( u sed to
lubricate the bag as it inflates) and by products of the
chemical reaction. Sodium hydroxide dust (similar to
lye soap) is produced as a by product of the
deployment reaction. The sodium hydroxide then
quickly reacts with atmospheric moisture and is
converted to sodium carbonate and sodium
bicarbonate (baking soda). Therefore, it is unlikely
that sodium hydroxide will be present after
deployment.
WARNING: SAFETY PRECAUTIONS MUST BE
OBSERVED WHEN HANDLING A DEPLOYED AIR
BAG ASSEMBLY. AFTER DEPLOYMENT, THE
METAL SURFACES OF THE AIR BAG ASSEMBLY
WILL BE HOT. ALLOW THE AIR BAG ASSEMBLY TO

carbonate and sodium bicarbonate (baking soda).
Therefore, it is unlikely that sodium hydroxide will be
present after deployment.
(Driver air bag assembly)
After the air bag assembly has been deployed, the
surface of the air bag may contain solid particulate. This
solid particulate consists primarily of by products of the
chemical reaction, Potassium Chloride and copper metal
dust. Compounds of Potassium Borate, Strontium
Chloride, Copper Chloride, and Ammonium Chloride may
be found in amounts of about 1 % (each) of the total
particulate.
Deployment Outside Vehicle (Pretensioner
Seat Belt Assembly)
Deployment outside the vehicle is proper when the
vehicle is to be returned to service. This includes, for
example, situations in which the vehicle will be returned to
useful service after a functionally or cosmetically deficient
pretensioner seat belt assembly is replaced. Deployment
and disposal of a malfunctioning pretensioner seat belt
assembly is, of course, subject to any required retention
period.
For deployment of a live (undeployed) pretensioner seat
belt assembly outside the vehicle, the deployment
procedure must be followed exactly. Always wear gloves
and safety glasses during this deployment procedure until
a deployed pretensioner seat belt assembly is scrapped
or until an undeployed pretensioner seat belt assembly is
shipped. Before performing the procedures you should
be familiar with servicing the system and with proper
handling of the pretensioner seat belt assembly.
Procedures should be read fully before they are
performed.
The following procedure requires use of SRS deployment
harness with appropriate pigtail adapter. Do not attempt
procedure without adapter.
WARNING: FAILURE TO FOLLOW PROCEDURES IN
THE ORDER LISTED MAY RESULT IN PERSONAL
INJURY. NEVER CONNECT DEPLOYMENT
HARNESS TO ANY POWER SOURCE BEFORE
CONNECTING DEPLOYMENT HARNESS TO THE
PRETENSIONER SEAT BELT ASSEMBLY.
DEPLOYMENT HARNESS SHALL REMAIN
SHORTED AND NOT BE CONNECTED TO A POWER
SOURCE UNTIL THE PRETENSIONER SEAT BELT IS
TO BE DEPLOYED. THE PRETENSIONER SEAT

Service Precautions for SRS
Component Service
CAUTION: When fasteners are removed, always
reinstall them at the same location from which they
were removed. If a fastener needs to be replaced, use
the correct part number fastener for that application.
If the correct part number fastener is not available, a
fastener of equal size and strength (or stronger) may
be used. fasteners that are not reused, and those
requiring thread locking compound will be called
out. The correct torque value must be used when
installing fasteners that require it. If the above
conditions are not followed, parts or system damage
could result.
WARNING: WHEN PERFORMING SERVICE ON OR
AROUND SRS COMPONENTS OR SRS WIRING,
FOLLOW THE PROCEDURES LISTED BELOW TO
TEMPORARILY DISABLE THE SRS. FAILURE TO
FOLLOW PROCEDURES COULD RESULT IN
POSSIBLE AIR BAG DEPLOYMENT, PERSONAL
INJURY OR OTHERWISE UNNEEDED SRS REPAIRS.
The SDM in Driver–Passenger SRS can maintain
sufficient voltage to cause a deployment for up to 15
seconds after the ignition switch is turned “OFF,” the
battery is disconnected, or the fuse powering the SDM is
removed.
Many of the service procedures require removal of the
“C–21” fuse, and disconnection of the air bag assembly
from the deployment loop to avoid an accidental
deployment. If the air bag assembly is disconnected from
the deployment loop as noted in the “Disabling the SRS”
procedure that follows, service can begin immediately
without waiting for the 15 second time period to expire.
Disabling The SRS
Removal
Turn the ignition switch to “OFF” and turn the steering
wheel so that the vehicle’s wheels are pointing straight
ahead.
1. Remove SRS fuse “C–21” from left dash side lower
fuse block or disconnect battery.
2. Disconnect yellow 2–pin connector at the base of
steering column.
3 . R e m o v e g l o v e b o x a s s e m b l y ; R e f e r t o “ P a s s e n g e r a i r
bag assembly replacement” in this section.
4. Disconnect passenger air bag assembly yellow 2–pin
connector behind the glove box assembly.
CAUTION: W i t h t h e “ C – 2 1 ” f u s e r e m o v e d a n d
ignition switch “ON,” the “AIR BAG” warning lamp
will be “ON.” This is normal operation and does not
indicate an SRS malfunction.
Enabling The SRS
Installation
Turn ignition switch to “LOCK” and remove key.
1. Connect yellow 2–pin connector passenger air bag
assembly.2. Install glove box assembly. Refer to “Passenger Air
Bag Assembly Replacement” in this section.
3. Connect yellow 2–pin connector at the base of the
steering column.
4. Install “AIR BAG” fuse “C–21” to left dash side lower
fuse block or connect battery.
Turn ignition switch to “ON” and verify that the “AIR BAG”
warning lamp turn on 3.5 seconds and then turns “OFF.” If
it does not operate as described, perform the “SRS
Diagnostic System Check” in this section.
Handling / Installation / Diagnosis
1. Air bag assembly should not be subjected to
temperatures above 93
C (200F).
2. Air bag assembly, and SDM should not be used if they
have been dropped from a height of 100 centimeters
(3.28 feet) or more.
3. When a SDM is replaced, it must be oriented with the
arrow on the SDM pointing toward the front of the
vehicle. It is very important for the SDM to be located
flat on the mounting surface, parallel to the vehicle
datum line. It is important that the SDM mounting
surface is free of any dirt or other foreign material.
4. Do not apply power to the SRS unless all components
are connected or a diagnostic chart requests it, as
this will set a diagnostic trouble code.
5. The “SRS Diagnostic System Check” must be the
starting point of any SRS diagnostics. The “SRS
Diagnostic System Check” will verify proper “AIR
BAG” warning lamp operation and will lead you to the
correct chart to diagnose any SRS malfunctions.
Bypassing these procedures may result in extended
diagnostic time, incorrect diagnosis, and incorrect
parts replacements.
Inspections Required After An Accident
CAUTION: C e r t a i n S R S c o m p o n e n t s m u s t b e
