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.

38. 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.

39. Separate the two ends of the passenger deployment

harness wires.

40. 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
gasses 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 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.
(Passenger 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 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.

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.

41. Short the driver deployment harness wires by

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

42. Carefully remove drop cloth from vehicle and clean

off any fragments or discard drop cloth entirely.

43. Disconnect driver deployment harness and

passenger deployment harness from vehicle and
discard.

44. 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.

45. 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.

46. 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
section.

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.

47. 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 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.

Special Tools

WARNING: TO AVOID DEPLOYMENT WHEN
TROUBLESHOOTING THE SRS, DO NOT USE
ELECTRICAL TEST EQUIPMENT SUCH AS A
BATTERY–POWERED OR AC–POWERED
VOLTMETER, OHMMETER, ETC., OR ANY TYPE OF
ELECTRICAL EQUIPMENT OTHER THAN THAT
SPECIFIED IN THIS MANUAL. DO NOT USE A NON
POWERED PROBE–TYPE TESTER.
INSTRUCTIONS IN THIS MANUAL MUST BE
FOLLOWED CAREFULLY, OTHERWISE PERSONAL
INJURY MAY RESULT.

5–8840–2421–0 (J–41433) SRS Driver/
Passenger Load Tool

The Supplemental Restraint System (SRS) Driver/
Passenger Load Tool 5–8840–2421–0 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 four 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.

5–8840–0285–0 (J–39200) DVM

The 5–8840–0285–0 Digital Multimeter (DVM) is the
preferred DVM for use in SRS diagnosis and repair.
However, 5–8840–0366–0 may be used if 5–8840–
0285–0 is not available. No other DVMs are approved
for SRS diagnosis and repair.

Scan Tool

The Tech 2 is used to read and clear SRS Diagnostic
Trouble Codes (DTCs). Refer to the Tech 2 Operator's
Manual for specific information on how to use the Tech
2.

5–8840–0385–0 (J–35616–A) Connector
Test Adapter Kit

The 5–8840–0385–0 Connector Test Adapter Kit must
be used whenever a diagnostic procedure requests
checking or probing a terminal. Using the appropriate
adapter will ensure that no damage to the terminal will
occur from the Digital Multimeter (DVM) prove, such as
spreading or bending. The adapter will also give an
idea of whether contact tension is sufficient, helping to
find an open or intermittent open due to poor terminal
contact.

5–8840–2468–0 (J–42986) SRS Deployment
Tool

The 5–8840–2468–0 Supplemental Restraint System
(SRS) Deployment Tool must be used for deployment of
the undeployed air bag.

901RX046

5–8840–2429–0 (J–42987) SRS Adapter For
Load Tool

The J–42987 SRS Adapter be used for connect
previous load tool to new SRS system when inspect
