10B-66 AIR BAG SYSTEM
Deployment/Activation Outside Vehicle
Use this procedure when the vehicle itself is used again (only the
air bag (inflator) module(s) and seat belt pretensioner(s) are dis-
posed).
1) Turn ignition switch to “LOCK”, position remove key and put
on safety glasses.
2) Check that there is no open, short or damage in special tool
(deployment harness). If any faulty is found, do not use it
and be sure to use new deployment harness.
Special tool
(A) : 09932-75030
3) Short (1) the two deployment harness leads together by fully
seating one banana plug into the other.
4) Remove air bag (inflator) module(s) and seat belt preten-
sioner(s) from vehicle, referring to SECTION 3C1, 10B and
10A. WARNING:
Deployment harness shall remain shorted and not be
connected to a power source until the air bag is to be
deployed and seat belt pretensioner is to be activated.
WARNING:
Always carry live air bag (inflator) module with trim
cover away from you.
When storing a live air bag (inflator) module or when
leaving a live air bag (inflator) module unattended on a
bench or other surface, always face the bag and trim
cover up and away from the surface. As the live pas-
senger air bag (inflator) module must be placed with its
bag (trim cover) facing up, place it on the workbench
with a slit (1) or use the workbench vise (2) to hold it
securely at its lower mounting bracket (3).
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.
