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.

Rear Seat Belt Removal and InstallationS6RW0D8106005
WARNING!
Be sure to read “Precautions on Service and
Diagnosis of Seat Belt” before starting to
work and observe every precaution during
work.

Removal
1) Fold rear seats referring to “Folding Rear Seats” in
Owners Manual.
2) Remove rear side sill scuff (1), quarter lower trim (2)
and quarter upper trim (3).
3) Remove rear seat belt referring to “Rear Seat Belt
Components”.Installation
Reverse removal procedure for installation noting the
following.
• Seat belt anchor bolts should have an unified fine
thread (7/16-20 UNF). Under no circumstances
should any different sized or metric screw threads be
used.Rear Seat Belt InspectionS6RW0D8106006
WARNING!
Be sure to read “Precautions on Service and
Diagnosis of Seat Belt” before starting to
work and observe every precaution during
work.

• Check the rear seat belt in the same way as “Front
Seat Belt Inspection”.
• As to seat belts with A-ELR, check them as follows.
– With vehicle at stop, pull seat belt all the way out,
let it retract a little and try to pull it. It should not be
pulled out, that is, it should be locked where
retracted.
– Let seat belt retract to its original state. Next, pull it
half way out, let it retract a little and try to pull it
again. It should be pulled out smoothly, that is it
should not be locked at this time.

The air bag system is designed to activate only in severe
frontal “a” and sideward “b” collisions. It is not designed
to activate in rear impacts, rollovers, or minor frontal and
sideward collisions, since it would offer no protection in
those types of accidents.

Diagnostic Information and Procedures
Air Bag Diagnostic System CheckS6RW0D8204001
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.
• When measurement of resistance or
voltage is required in the flow, use a tester
along with a correct terminal adapter from
special tool (Connector test adapter kit).
• When a check for proper connection is
required, refer to “Inspection of
Intermittent and Poor Connections”.
• If an open circuit in the air bag wire
harness damaged, connector or terminal is
found, replace the wire harness,
connectors and terminals as an assembly.

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 light operation through
“AIR BAG” warning light and whether air bag DTCs
exist.)
2) Refer to the proper diagnostic 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.)
