Front Seat Belt InspectionS6RW0D8106003
WARNING!
• Never attempt to disassemble or repair the
seat belt pretensioner (retractor). If any
abnormality is found, be sure to replace it
with new one as an assembly.
• Be sure to read “Precautions on Service
and Diagnosis of Seat Belt”, before
starting to work and observe every
precaution during work. Neglecting them
may result in personal injury or
unactivation of the seat belt pretensioner
when necessary.
• Never measure resistance of pretensioner
or disassemble it. Otherwise, personal
injury may result.

CAUTION!
If seat belt pretensioner (retractor) was
dropped from a height of 30 cm (1 ft) or more,
it should be replaced.

Seat belts and attaching parts can affect the vital
components and systems of a vehicle.
Therefore, they should be inspected carefully and
replaced with genuine parts only.
Seat Belt
• The seat belt webbing or strap should be free from
damage.
Retractor (with Seat Belt Pretensioner)
1) Let the seat belt retract fully to confirm its easy
retraction.
• The retractor should lock webbing when pulled
quickly.
• The front seat belt retractor (1) should pass the
inspection and should lock webbing even when
tilted (approx. 15°) toward the fore and aft or right
and left directions.2) Check retractor (1) with seat belt pretensioner
appearance visually for following symptoms and if
any one of them is applicable, replace it with a new
one as an assembly.
• Pretensioner has activated.
• There is a crack in seat belt pretensioner
(retractor).
• Seat belt pretensioner (retractor) is damaged or a
strong impact (e.g., dropping) was applied to it.
Anchor Bolt
• Anchor bolts should be torqued to specification.
Belt Latch
• It should be secure when latched.
Seat Belt Buckle Switch
Check driver side seat belt switch and passenger side
seat belt switch for continuity by using ohmmeter.

• 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 pretensioner, be sure to activate
it before discarding it.
• When grease, cleaning agent oil, water, etc., got on
the seat belt pretensioners (retractor 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 included in main harness (1),
instrument panel harness (4), floor harness (3), seat
harness (5) and curtain air bag harness (6). 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.
