23. Verify that the inside of the vehicle and the area

surrounding the vehicle are clear of all people and
loose or flammable objects.

24. Stretch the driver and passenger deployment

harness to their full length.

25. Completely cover windshield area and front door

window openings with a drop cloth, blanket or similar
item. This reduces the possibility of injury due to
possible fragmentation of the vehicle’s glass or
interior.

26. Notify all people in the immediate area that you intend

to deploy the air bags. The deployment will be
accompanied by a substantial noise which may
startle the uninformed.

27. Separate the two ends of the driver deployment

harness wires.

WARNING: DEPLOYMENT WIRES SHALL REMAIN
SHORTED AND NOT BE CONNECTED TO A POWER
SOURCE UNTIL THE AIR BAG IS 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 WIRES TO THE POWER SOURCE
SHOULD ALWAYS BE THE FINAL STEP IN THE AIR
BAG ASSEMBLY DEPLOYMENT PROCEDURE.
FAILURE TO FOLLOW PROCEDURES IN THE
ORDER LISTED COULD RESULT IN PERSONAL
INJURY.

NOTE: When the 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 bags.

28. Connect the driver deployment harness wires to a

power source to immediately deploy the driver air bag
assembly. Recommended application: 12 volts
minimum, 2 amps minimum. A vehicle battery is
suggested.

29. Separate the two ends of the passenger deployment

harness wires.

30. Connect the passenger deployment harness wires to

a power source to immediately deploy the passenger
air bag assembly. Recommended application: 12
volts minimum, 2 amps minimum. A vehicle battery is
suggested.(Driver air bag assembly) 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 an air
bag assembly has been deployed, the surface of the
air bag may contain a powdery residue. This powder
consists primarily of cornstarch (used 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.(Passenger air bag
assembly) The passenger inflator requires no special
precaution after deployment. 95% of the particulate
emission are potassium chloride (KLC), which is
commonly sold as an edible salt–substitutes. even if
water is applied. Post deployment products are
relatively pH neutral. Disposing the inflator by burying
it in a landfill will not products any hazardous
products. As with any dusty environment, safety
goggles, dust mask and gloves should be worn.

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 VERY HOT. ALLOW THE AIR BAG
ASSEMBLY TO COOL BEFORE HANDLING ANY
METAL PORTION OF IT. DO NOT PLACE THE HOT
DEPLOYED AIR BAG ASSEMBLY NEAR ANY
FLAMMABLE OBJECTS. FAILURE TO FOLLOW
PROCEDURES COULD RESULT IN FIRE OR
PERSONAL INJURY.

After an air bag assembly has been deployed, the
metal canister and surrounding areas of the air bag
assembly will be very hot. Do not touch the metal
areas of the air bag assembly for about 30 minutes
after deployment. If the deployed air bag assembly
must be moved before it is cool, wear gloves and
handle by the air bag or trim cover.

31. Short the driver deployment harness wires by twisting

together one end from each. Repeat this procedure
for the passenger deployment harness.

32. Carefully remove drop cloth from vehicle and clean off

any fragments or discard drop cloth entirely.

33. Disconnect driver deployment harness and

passenger deployment harness from vehicle and
discard.

34. In the unlikely event that either or both of the air bag

assemblies did not deploy after following these
procedures, proceed immediately with Steps 36
through 37. If the air bag assembly deployed, proceed
to step 35.

35. With both air bags deployed, the vehicle may be

scrapped in the same manner as a non–SRS
equipped vehicle.

NOTE: The remaining steps are to be followed in the
unlikely event that the air bag assembly did not deploy
after following these procedures.

36. Remove the undeployed air bag assembly (s) from

the vehicle. For driver air bag assembly refer to in the
“Passenger Air Bag Assembly Removal” in this
manual.

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 AND TRIM
COVER UP, 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 COULD
RESULT IN PERSONAL INJURY.

37. Temporarily store the air bag assembly with the air

bag opening facing up, away from the surface upon
which it rests.

Deployed Air Bag Assembly Handling

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.
This powder consists primarily of cornstarch (used 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.

J–41433 SRS Driver/Passenger Load Tool

901RS146

The SRS Driver/Passenger Load Tool J–41433 is used
only when called for in this section. It is used as a
diagnostic aid and safety device to prevent inadvertent air
bag assembly deployment.
The load tool has three yellow connectors attached to its
case.
The three small connectors are electrically functional and
serve as resistive load substitutions.
No more than two connectors are used at any time. One
of the small connectors is used to substitute for the load of
the driver air bag assembly when it is connected at the top
of the column to the SRS coil assembly. Another small
connector is used to substitute for the load of the driver air
bag assembly and the SRS coil assembly when it is
connected at the base of the column to the SRS wiring
harness. The third small connector is used to substitute
for the load of the passenger air bag assembly when
connected to the passenger air bag assembly harness
connector.
By substituting the resistance of the load tool when called
for, a determination can be made as to whether an inflator
circuit component is causing system malfunction and
which component is causing the malfunction. The load
tool should be used only when specifically called for in the
diagnostic procedures.

J–39200 DVM

901RS153

The J–39200 DVM is the preferred DVM for use in SRS
diagnosis and repair. However, J–34029—A may be
used if J–39200 is not available. No other DVMs are
approved for SRS diagnosis and repair.

Scan Tool
