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
BELT ASSEMBLY WILL IMMEDIATELY DEPLOY THE
PRETENSIONER SEAT BELT WHEN A POWER
SOURCE IS CONNECTED TO IT. WEAR GLOVES
AND SAFETY GLASSES THROUGHOUT THIS
ENTIRE DEPLOYMENT AND DISPOSAL
PROCEDURE.
1. Turn ignition switch to “LOCK”, remove key.
2. Remove the pretensioner seat belt assembly from
vehicle. Refer to “Pretensioner Seat Belt Removal” in
this manual.
3. Prepare SRS deployment harness.
901HV009
4. Short the two SRS deployment harness leads
together by fully seating one banana plug into the
other. SRS deployment harness shall remain shorted
and not be connected to a power source until the
pretensioner seat belt is to be deployed.
5. Place the pretensioner seat belt assembly on a work
bench or other surface away from all loose or
flammable objects.
WARNING: WHEN FIXING THE DEPLOYMENT
DEVICE OF PRETENSIONER SEAT BELT, THE
DEPLOYMENT DEVICE SHOULD BE FIXED AWAY
FROM OTHER PERSON
6. Clear a space on the ground about 183 cm (six feet) in
diameter where the pretensioner seat belt assembly
is to be deployed. 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 there
is no activity and sufficient ventilation is
recommended. Ensure no loose or flammable
objects are within the deployment area.
7. Stretch the SRS deployment harness and pigtail
adapter from the pretensioner seat belt assembly to
its full length.
8. 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.
9. 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 belt
assembly will immediately deploy the pretensioner
seat belt when a power source is connected to it.
10. Verify that the area around the pretensioner seat belt
assembly is clear of all people and loose or flammable
objects.
11. Notify all people in the immediate area that you intend
to deploy the driver air bag. The deployment will be
accompanied by a substantial noise which may
startle the uninformed.
12. Connect the pretensioner seat belt to the pigtail
adapter on the SRS deployment harness.
