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.

• When an open in air bag wire harness, damaged wire harness, connector or terminal is found, replace wire
harness, connectors and terminals as an assembly.
• When installing it, be careful so that the air bag wire harness is not caught or does not interfere with other
parts.
• Make sure air bag system grounding point (2) is clean and ground is securely fastened for optimum metal-to-
metal contact. Poor grounding can cause intermittent
problems that are difficult to diagnose.Precautions on Disposal of Air Bag and Seat
Belt Pretensioner
S7RS0B8200003
Do not dispose of the live (undeployed) air bag (inflator)
modules and the live (inactivated) seat belt
pretensioners.
When disposal is necessary, be sure to deploy / activate
the air bag and seat belt pretensioner according to
deployment / activation procedure described in “Air Bag
(Inflator) Module and Seat Belt Pretensioner Disposal”.
WARNING!
Failure to follow proper air bag (inflator)
module and seat belt pretensioner disposal
procedures can result in air bag deployment
and pretensioner activation which could
cause personal injury. Undeployed air bag
(inflator) module and inactivated seat belt
pretensioner must not be disposed of
through normal refuse channels.
The undeployed air bag (inflator) module and
inactivated seat belt pretensioner contain
substances that can cause severe illness or
personal injury if the sealed container is
damaged during disposal.
General Description
Air Bag System ConstructionS7RS0B8201001
With the air bag system which includes front air bags,
side curtain-air bag and side-air bags for both the
driver’s and passenger’s sides as well as the seat belt
pretensioners, the sag of the s eat belt is taken up (for
seat belt with pretensioner), the driver air bag (inflator)
module is deployed from th e center of the steering
column and the passenger air bag (inflator) module from
the top of the instrument panel in front of the front
passenger seat in occurrence of a front collision with an
impact larger than a certain set value to supplement
protection offered by the driver and front passenger seat
belts.
Side-air bag (inflator) module is deployed from the side
of the seat back in occurrence of a sideward collision
with an impact larger than a certain set value.
Side curtain-air bag (inflator) module is deployed from
the roof side in occurrence of a sideward collision with
an impact larger than a certain set value.

Diagnostic Information and Procedures
Air Bag Diagnostic System CheckS7RS0B8204001
WARNING!
To avoid deployment when troubleshooting
the air bag system, do not use electrical test
equipment such as a battery powered or AC
powered voltmeter, ohmmeter, etc., or any
type of electrical equipment other than that
specified in this manual. Do not use a non-
powered probe type tester.
Instructions in this manual must be followed
carefully, otherwise personal injury may
result.
CAUTION!
The order in which DTCs are diagnosed is
very important. Failure to diagnose the DTCs
in the order specified may result in extended
diagnostic time, incorrect diagnosis and
incorrect parts replacement.
The diagnostic procedures used are designed to find
and repair air bag system malfunctions.
To get the best results, it is important to use the
diagnostic flow and follow the sequence in the following.1) Perform the “Air Bag Diagnostic System Check Flow”.
(The “Air Bag Diagnostic System Check Flow” must
be the starting point of any air bag system diagnosis.
The “Air Bag Diagnostic System Check Flow” checks
for proper “AIR BAG” warning right operation
through “AIR BAG” warning right and whether air
bag DTCs exist.)
2) Refer to the proper diagnost ic flow as directed by the
“Air Bag Diagnostic System Check Flow”.
(The “Air Bag Diagnostic System Check Flow” will
lead you to the correct flow to diagnose any air bag
system malfunctions. Bypassing these procedures
may result in extended diagnostic time, incorrect
diagnosis and incorrect parts replacement.)
3) Repeat the “Air Bag Diagnostic System Check Flow” after any repair or diagnostic procedures have been
performed.
(Performing the “Air Bag Diagnostic System Check
Flow” after all repair or diagnostic procedures will
ensure that the repair has been made correctly and
that no other malfunctions exist.)
