KEY CODING
KEY USAGE AND IDENTIFICATION
Key is used for ignition and door lock cylinder. Keys are cut on
both edges to make them reversible.
Key identification is obtained from five character key code
stamped on key code tag. Using this key code, key code cutting
combination can be determined from a code list (available to own-
ers of key cutting equipment from suppliers).
If key codes are not available from records or tags, key code can
be obtained from the right hand door lock cylinder (if lock has not
been replaced). Lock cylinders supplied by the factory as service
parts are unmarked.
If original key is available, key code cutting combination can be
determined by laying key.

REMOVAL
1) Disconnect negative battery cable at battery.
2) Disable air bag system. Refer to “DISABLING AIR BAG SYSTEM” of “SERVICE PRECAUTIONS” under
“ON-VEHICLE SERVICE” in Section 10B.
3) Remove center pillar lower trim.

INSPECTION
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
Its webbing or strap should be free from damage.
Retractor assembly
It should lock webbing when pulled quickly.
The front seat belt retractor assembly (1) should pass the
above inspection and should lock webbing even when tilted
(approx. 15°) toward the fore and aft or right and left direc-
tions.
Check retractor assembly (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 assem-
bly.
Pretensioner has activated.
There is a crack in seat belt pretensioner (retractor assem-
bly).
Wire harness or connector (2) is damaged.
Seat belt pretensioner (retractor assembly) 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. WARNING:
Never measure resistance of pretensioner or disassem-
ble it. Otherwise, personal injury may result.
CAUTION:
If seat belt pretensioner (retractor assembly) was
dropped from a height of 30 cm (1 ft) or more, it should
be replaced.

RESTRAINT SYSTEM 10-7
INSTALLATION
Install in reverse order of removal, 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.
Connect Yellow connector (1) for seat belt pretensioner
securely and fit seat belt pretensioner connector onto body.
a) Connect connector
b) Lock connector with lock lever
Enable air bag system. Refer to “ENABLING AIR BAG SYS-
TEM” under “SERVICE PRECAUTIONS” in Section 10B.

10B-50 AIR BAG SYSTEM
LIVE (INACTIVATED) SEAT BELT PRETENSIONER
Special care is necessary when handling and storing a live (inac-
tivated) seat belt pretensioners.
Also, when the seat belt pretensioners activate, gas is generated
and the seat belt (1) is retracted into the retractor assembly (2)
quickly.
Note, therefore, that if they activate accidentally, the seat belt pre-
tensioners and other object(s) around them may be thrown
through the air.
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 (inacti-
vated) 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 immedi-
ately 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:
When placing a live air bag (inflator) module on bench or
other surface, always face the bag up, away from the sur-
face. 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 a free space is provided to
allow the air bag to expand in the unlikely event of acci-
dental deployment.
Otherwise, personal injury may result.

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.
