WARNING!
Never attempt to measure the resistance of
the seat belt pretensioners. It is very
dangerous as the electric current from the
tester may activate pretensioner.

• Never attempt to disassemble the seat belt
pretensioners (retractor assembly).
• If any abnormality is found, be sure to replace it with
new one as an assembly.
• When an abnormality is noted as existing in the live (inactivated) seat belt preten sioner, be sure to activate
it before discarding it.
• When grease, cleaning agent oil, water, etc., got on the seat belt pretensioners (r etractor assembly), wipe
it off immediately with a dry cloth.
• If seat belt pretensioner was dropped from a height of 30 cm (1 ft) or more, it should be replaced with a new
one as an assembly.
WARNING!
• For handling and storage of a live seat belt pretensioner, select a place where the
ambient temperature below 65 °C (150 ° F),
without high humidity and away from
electric noise.
• Never carry the seat belt pretensioner by webbing.
• When placing a live seat belt pretensioner on the workbench or other surface, be sure
not to lay it with its exhaust hole (1)
provided side facing down. It is also
prohibited to put something on its face
with an exhaust hole (1) or to put a seat
belt pretensioner on top of another.
Otherwise, personal injury may result.

Deployed Air Bag (Inflator) Module and Activated
Seat Belt Pretensioner
WARNING!
• The air bag (inflator) module and seat belt
pretensioner immediately after
deployment/activation is very hot. Wait for
at least 30 minutes to cool it off before
proceeding the work.
• Do not apply water, oil, etc. to deployed air bag (inflator) module and to activate seat
belt pretensioner.
• After an air bag (inflator) module 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. As with
many service procedures, gloves and
safety glasses should be worn.
• Wash your hands with mild soap and water after completing the work.

Refer to the procedure described under “Deployed Air
Bag (Inflator) Module and Activated Seat Belt
Pretensioner Disposal” for disposal.
Air Bag Wire Harness and Connector
Air bag wire harness is includ ed in main harness (1),
instrument panel harness (4), floor harness (3) and seat
harness (5). Air bag wire harness can be identified easily
as the part of connector side wire harness is covered
with a yellow protection tube. Be very careful when
handling it.

Inspection of Intermittent and Poor
Connections
S7RS0B8204048
Most intermittents are caused by faulty electrical
connections or wiring. When a check for proper
connection is requested in a diagnostic flow, perform
careful check of suspect circuits.
If any abnormality is found, repair or replace as a wire
harness assembly.
• Poor mating of connector halves, or terminals not fully seated in the connector body (backed out).
• Dirt or corrosion on the terminals. The terminals must be clean and free of any foreign material which could
impede proper terminal contact.
However, cleaning the terminal with a sand paper or
the like is prohibited.
• Damaged connector body, exposing the terminals to moisture and dirt, as well as not maintaining proper
terminal orientation with the component or mating
connector.
• Improperly formed or damaged terminals. Check each connector terminal in problem circuits
carefully to ensure good contact tension by using the
corresponding mating terminal included in the
connector test adapter kit (special tool).
If contact tension is not e nough, reform the terminal to
increase contact tension or replace it.
Special tool
(A): 09932-76010 Connector test adapter kit • Poor terminal-to-wire connection.
Check each wire harness in problem circuits for poor
connection by shaking it by hand lightly. If any
abnormal condition is found, change the wire harness
assembly or component parts with new ones.
• Wire insulation which is rubbed through, causing an intermittent short as the bare area touches other
wiring or parts of the vehicle.
• Wire broken inside the insulation. This condition could cause a continuity check to show a good circuit, but if
only 1 or 2 strands of a multi-strand-type wire are
intact, resistance could be far too high.

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.

• Never carry seat belt pretensioner by webbing.
• When placing seat belt pretensioner on workbench or other surface, be sure to lay
it with its exhaust hole (1) side facing up. It
is also prohibited to put something on seat
belt pretensioner.
Otherwise, personal injury may result.

6) Set air bag (inflator) module or seat belt pretensioner
as follows.
• For driver air bag (inflator) module
a. Clear space (3) on ground about 185 cm (6 ft) in diameter where driver air bag (inflator)
module (1) is set for deployment. Paved,
outdoor location where there is no activity is
preferred. If outdoor location is not available,
use space on shop floor where there is no
activity and sufficient ventilation is provided.
Ensure no loose or flammable object exists
within deployment area.
b. Place driver air bag (inflator) module (1) with its vinyl trim cover facing up (2) on ground in
step a.
[A]: Always carry air bag (inflator) module with trim cover (air bag opening) away from body.
[B]: Always place air bag (inflator) module on workbench with trim cover (air bag opening) up, away from loose objects.
