You should wear gloves and safety glasses. After the
pretensioner seat belt has been deployed, the surface of
the pretensioner seat belt cylinder may heating up.
Air Bag Assembly and/or Pretensioner
Seat Belt Scrapping Procedure.
During the cause of vehicle’s useful life, certain situations
may arise which will necessitate the disposal of a live air
bag and/or pretensioner seat belt. (This information
covers proper procedures for disposing of a live air bag
assembly and/or pretensioner seat belt.)
Before a live air bag assembly can be dispose off, it must
be deployed.
A live air bag assembly and/or pretensioner seat belt
must not be disposed of though normal refuse channels.
WARNING: FAILURE TO FOLLOW PROPER
SUPPLEMENTAL RESTRAINT SYSTEM (SRS) AIR
BAG ASSEMBLY DISPOSAL PROCEDURES CAN
RESULT IN AIR BAG DEPLOYMENT WHICH MAY
CAUSE PERSONAL INJURY. AN UNDPLOYED AIR
BAG ASSEMBLY MUST NOT BE DISPOSED OF
THROUGH NORMAL REFUSE CHANNELS. THE
UNDEPLOYED AIR BAG ASSEMBLY CONTAINS
SUBSTANCES THAT CAN CAUSE SEVERE ILLNESS
OR PERSONAL INJURY IF THE SEALED CONTAINER
IS DAMAGED DURING DISPOSAL. DISPOSAL IN
ANY MANNER INCONSISTENT WITH PROPER
PROCEDURES MAY BE A VIOLATION OF LOCAL
LAW.
In situations which require deployment of a live air bag
assembly, deployment may be accomplished inside or
outside the vehicle. The method employed depends
upon the final disposition of the particular vehicle, as
noted in “Deployment Outside Vehicle” and “Deployment
Inside Vehicle” in this section.
Cautions About Air Bag Deployment And
Disposal
Failure to follow proper procedures could result in
erroneous air bag deployment which may cause personal
injury be sure to follow proper procedures.
1. Turn off (Lock) the ignition switch and disconnect the
minus terminal of the battery, then start the work 15 or
more sec later. (Air bag is designed to work by the
back-up power source even if the battery power
source is cut off at vehicle collision).
2. Be sure not to disassemble the air bag.
3. Do not give an impact to the air bag and bring the air
bag close to magnet. (The air bag could deploy
unexpectedly).4. Place the air bag with its trim cover up.
5. Do not let the air bag deploy directly on the floor. (The
air bag may be blown off 2
3 m (6.5 or 10 feet)).
6. Be sure to install the air bag firmly to a deployment
tool (fixing tool).
7. Set a battery 10 m (33 feet) or more away from the air
bag.
8. Before disconnecting air bag harness, ground the
worker by touching the vehicle outer panel with bare
hand.
9. When connecting or disconnecting the harness, do
not work just in front of the air bag.
10. As deployment gives rise to big sound, warn the
people around against it. Further, try to reduce the
sound by covering the steering wheel or tires, and
shut the vehicle windows in case of deployment
inside the vehicle.
11. As deployment generates smoke, select a well
ventilated place. (In case of deployment indoors,
avoid deployment just under a fire alarm, smoke
sensor, and fluorescent lamps).
12. Be careful not to inhale the smoke after deployment.
13. If part of the vehicle glass is damaged, cover the
vehicle with a car cover to prevent the glass from
braking at the time of deployment.
14. Do not touch the air bag immediately after
deployment, since it remains hot for 30 minutes.
15. Do not water the air bag immediately after
deployment.
16. Wear safety glasses and gloves throughout the work
and wash the glasses and gloves after the work.
17. Do not reuse the removed air bag for another vehicle.
(Deployment characteristic is different with vehicle
types).
Deployment Outside Vehicle (Driver Air
Bag 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
air bag assembly is replaced. Deployment and disposal
of a malfunctioning air bag assembly is, of course, subject
to any required retention period.
For deployment of a live (undeployed) air bag assembly
outside the vehicle, the deployment procedure must be
followed exactly. Always wear safety glasses during this
deployment procedure until a deployed air bag assembly
is scrapped or until an undeployed air bag assembly is
shipped. Before performing the procedures you should
be familiar with servicing the SRS and with proper
handling of the air bag assembly. Procedures should be
read fully before they are performed.
The following procedure requires use of 5–8840–2468–0
SRS deployment harness with appropriate pigtail
adapter. Do not attempt procedure without
5–8840–2468–0 adapter.
WARNING: FAILURE TO FOLLOW PROCEDURES IN
THE ORDER LISTED MAY RESULT IN PERSONAL
INJURY. NEVER CONNECT DEPLOYMENT

SUPPLEMENTAL RESTRAINT SYSTEM 9J–20
13. Wash your hands with mild soap and water afterward.
NOTE: The remaining steps are to be followed in the
unlikely event that the air bag assembly did not deploy
after following the above procedures.
14. Ensure that the SRS deployment harness has been
disconnected from the power source and that its two
banana plugs have been shorted together by fully
seating one banana plug into the other.
827RW055
15. Disconnect the pigtail adapter from the air bag
assembly.
WARNING: WHEN STORING A LIVE AIR BAG
ASSEMBLY OR WHEN LEAVING A LIVE AIR BAG
ASSEMBLY UNATTENDED ON A BENCH OR OTHER
SURFACE, ALWAYS FACE THE BAG UP AND AWAY
FROM THE SURFACE. THIS IS NECESSARY SO
THAT A FREE SPACE IS PROVIDED TO ALLOW THE
AIR BAG TO EXPAND IN THE UNLIKELY EVENT OF
ACCIDENTAL DEPLOYMENT. FAILURE TO FOLLOW
PROCEDURES MAY RESULT IN PERSONAL INJURY.
16. Temporarily store the air bag assembly with the bag
facing up, away from the surface upon which it rests.
066RW030
Deployment Inside Vehicle (Vehicle
Scrapping Procedure)
Deployment inside vehicle is proper when the vehicle is to
be destroyed or salvaged for component parts. This
includes, but is not limited to, the following situations:
1. The vehicle has completed its useful life.
2. The vehicle has been damaged beyond repair in a
nondeployment type accident.
3. The vehicle has been stripped or damaged beyond
repair in a theft.
4. The vehicle will be salvaged for component parts to
be used on a vehicle with a different Vehicle

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

Service Precautions
WARNING: SAFETY PRECAUTIONS MUST BE
FOLLOWED WHEN HANDLING A DEPLOYED AIR
BAG ASSEMBLY. AFTER DEPLOYMENT, THE AIR
BAG ASSEMBLY SURFACE MAY CONTAIN A SMALL
AMOUNT OF SODIUM HYDROXIDE, A BY–PRODUCT
OF THE DEPLOYMENT REACTION, THAT IS
IRRITATING TO THE SKIN AND EYES. MOST OF THE
POWER ON THE AIR BAG ASSEMBLY IS
HARMLESS. AS A PRECAUTION, WEAR GLOVES
AND SAFETY GLASSES WHEN HANDLING A
DEPLOYED AIR BAG ASSEMBLY, AND WASH YOUR
HANDS WITH MILD SOAP AND WATER
AFTERWARDS.
WARNING: WHEN CARRYING A LIVE AIR BAG
ASSEMBLY, MAKE SURE THE BAG AND TRIM
COVER ARE POINTED AWAY FROM YOU. NEVER
CARRY AIR BAG ASSEMBLY BY THE WIRES OR
CONNECTOR ON THE UNDERSIDE OF MODULE. IN
THE CASE OF AN ACCIDENTAL DEPLOYMENT, THE
BAG WILL THEN DEPLOY WITH MINIMAL CHANCE
OF INJURY. WHEN PLACING ALIVE AIR BAG
ASSEMBLY ON A BENCH OR OTHER SURFACE,
ALWAYS FACE BAG AND TRIM COVER UP, AWAY
FROM THE SURFACE. NEVER REST A STEERING
COLUMN ASSEMBLY ON THE STEERING WHEEL
WITH THE AIR BAG ASSEMBLY FACE DOWN AND
COLUMN VERTICAL. THIS IS NECESSARY SO THAT
A FREE SPACE IS PROVIDED TO ALLOW THE AIR
BAG ASSEMBLY TO EXPAND IN THE UNLIKELY
EVENT OF ACCIDENTAL DEPLOYMENT.
OTHERWISE, PERSONAL INJURY COULD RESULT.
NOTE: In the event deployment has occurred, inspect
coil assembly wire for any signs of scorching, melting or
any other damage due to excessive heat. If the coil has
been damaged, replace it.
Removal
1. Disable the SRS (Refer to “Disabling the SRS” in this
section).
2. Loosen the air bag assembly fixing bolts from behind
the steering wheel assembly using a TORX
d r i v e r o r
equivalent until the air bag assembly can be released
from steering wheel.
