HANDLING AND STORAGE
SDM
Never attempt disassembly of SDM.
When storing SDM, select a place where neither high tem-
perature nor high humidity is anticipated and oil, water and
dust are kept off.
If SDM has been dropped, replace it with a new one.
If installation part of SDM was damaged, repair that part
completely before reinstallation.
All SDM and mounting bracket fasteners must be carefully
torqued and the arrow must be pointed toward the front of
the vehicle to ensure proper operation of the air bag system.
WARNING:
Never power up air bag system when SDM is not rigidly
attached to the vehicle. Otherwise, personal injury may
result.
CAUTION:
After detecting one time of such collision as to meet
deployment conditions, the SDM must not be used. Refer
to “AIR BAG DIAGNOSTIC SYSTEM CHECK” when
checking the SDM.

DEPLOYMENT/ACTIVATION OUTSIDE VEHI-
CLE
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 3C, 10B and
10. 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.
