WARNING!
During service procedures, be very careful
when handling a Sensing and Diagnostic
Module (SDM).
Be sure to read “Precautions on Service and
Diagnosis of Air Bag System” before starting
to work and observe every precaution during
work. Neglecting them ma y result in personal
injury or inactivation of the air bag system
when necessary.

Removal
1) Disconnect negative cable at battery.
2) Disable air bag system referring to “Disabling Air Bag System”.
3) Remove center console box referring to “Console Box Components in Section 9H”.
4) Disconnect SDM connector (1) from SDM (2).

Deployment / Activation Outside of Vehicle
When you intend to return the vehicle to service, deploy
the air bag (inflator) module(s) or activate seat belt
pretensioner(s) outside of the vehicle.1) Turn ignition switch to LOCK position and remove key.
2) Wear safety glasses during this deployment / activation procedure.
3) Check that there is no open, short or damage in special tools (deployment harness (A) and adapter
cable (B)). If any faulty is found, do not use it and be
sure to use new special tool.
Special tool
(A): 09932-75031
(B): 09932–76510
4) Short two deployment harness leads (1) together by fully seating one banana plug into the other.
WARNING!
Deployment harness (A) shall remain shorted
and not be connected to 12 volts vehicle
battery till you are ready to deploy air bag
module or activate seat belt pretensioner.

5) Remove air bag (inflator) module(s) or seat belt pretensioner(s) from vehicle referring to “Driver Air
Bag (Inflator) Module Re moval and Installation”,
“Passenger Air Bag (Inflator) Module Removal and
Installation”or “Front Seat Belt Removal and
Installation in Section 8A”.
WARNING!
• For handing and storage of live air bag (inflator) module, select place where
ambient temperature below 65 °C (150 °F),
without high humidity and away from
electric noise.
• Always carry live air bag (inflator) module with trim cover away from you.
• When storing live air bag (inflator) module or when leaving live air bag (inflator)
module unattended on bench or other
surface, always face trim cover up and
away from surface. As the live passenger
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). It is also
prohibited to place anything on top of the
trim cover and stack air bag (inflator)
modules. This is necessary so that free
space is provided to allow air bag (inflator)
module to expand in the unlikely event of
accidental deployment.
Failure to follow procedures may result in
personal injury.

Deployment / Activation Inside of Vehicle
When the vehicle will be destroyed, or salvaged for
component parts, deploy the air bag modules and/or
activate seat belt pretensioners installed on vehicle.
NOTE
If equipped with the seat belt pretensioners,
activate both side of seat belt pretensioners
at the same time when using special tool (C).

1) Turn ignition switch to LOCK position, remove key
and put on safety glasses.
2) Remove all loose objects from front seats and instrument panel.
3) Disconnect air bag (inflator) module or seat belt pretensioner connector as follows.
• For driver and passenger air bag (inflator) module [A]
Remove glove box from instrument panel and
disconnect driver and passenger air bag (inflator)
module connector (1).
• For side-air bag (inflator) module [B] Disconnect side-air bag (inflator) module
connectors (2) under front seat cushion.
• For side curtain-air bag (inflator) module [C] Remove rear pillar trim and disconnect side
curtain-air bag (inflator) module connectors (3).
• For seat belt pretensioners (right and left) [D] Remove both side (driver and passenger side)
center pillar lower trim an d disconnect seat belt
pretensioner connectors (4).
4) Confirm that each air bag (inflator) module and/or seat belt pretensioners is securely mounted.
