10A-4 SEAT BELT
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
The seat belt webbing or strap should be free from damage.
Fully extend the seat belt to make sure there are no twists or tears
in it.
Retractor assembly
Let the seat belt retract fully to confirm its easy retraction.
The retractor assembly should lock webbing when pulled quickly.
The retractor assembly should lock webbing even when tilted
(approx. 15) toward the fore and aft or right and left directions.
Anchor bolt
Inspect all seat belt anchor bolts to verify that they are secure.
All anchor bolts should be secure and torqued to specification.
Belt latch
Belt latch should be secure when latched.
Inspect the seat belt buckle, ensuring that it locks and unlocks
easily.
After buckling the seat belt, tug sharply on the belt, checking that
the buckle remains locked.
Warning system
Check driver side seat belt strap switch for continuity by using ohm-
meter.
Without inserted buckle tongue to buckle catch:
Terminal ªAº and ªBº: Continuity
With inserted buckle tongue to buckle catch:
Terminal ªAº and ªBº: No continuity ()
As to seat belts with ALR (other than driver side seat belt), check
them as follows in addition to above check.
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.

AIR BAG SYSTEM 10B-3
GENERAL DESCRIPTION
With the air bag system which includes air bags for both the driver's
and passenger's sides as well as the seat belt pretensioners (if
equipped), the sag of the seat belt is taken up, the driver air bag (in-
flator) module is deployed from the 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.
The air bag system is designed to activate only in severe frontal col-
lisions. It is not designed to activate in rear impacts, side impacts,
rollovers, or minor frontal collisions, since it would offer no protec-
tion in those types of accidents.

AIR BAG SYSTEM 10B-7
Special Tool (Air Bag Driver/Passenger Load Tool)
(B): 09932-75010
This tool is used only when called for in this section. It is used as
a diagnostic aid and safety device to prevent inadvertent air bag (in-
flator) module deployment and seat belt pretensioner activation.
The load tool has three connectors attached to its case are electri-
cally functional and serve as resistive load substitutions.
No more than two connectors are used at any time.
One of connectors (ªAº: BASE OF COLUMN) is used to substitute
the load of the driver air bag (inflator) module and the contact coil
assembly when it is connected at the base of the column to the air
bag wire harness.
Another connector (ªBº: STEERING WHEEL) is used to substitute
the load of followings.
Driver air bag (inflator) module when it is connected at the top of
the column to the contact coil assembly.
Passenger air bag (inflator) module when it is connected to the
air bag harness connector for passenger air bag (inflator) module.
Driver and passenger seat belt pretensioner when it is connected
to air bag harness connector for driver and passenger seat belt
pretensioner.
The third connector (ªCº: PASSENGER INFLATOR) is not used.
By substituting the resistance of the load tool when called for, a de-
termination can be made as to whether an inflator circuit compo-
nent is causing system malfunction and which component is caus-
ing the malfunction.
The load tool should be used only when specifically called for in the
diagnostic procedures.
