GENERAL DESCRIPTION
Seat belt with ELR
The seat belt with Emergency Locking Retractor (ELR) is designed so that it locks immediately (to prevent the web-
bing from being pulled out of the retractor any further) when any of the following items is detected as exceeding
each set value; speed at which the webbing is pulled out of the retractor, acceleration or deceleration of the vehicle
speed, and inclination.
Seat belt with A-ELR
The automatic and emergency locking retractor (A-ELR) works as an Emergency Locking Retractor (ELR) till its
webbing is pulled all the way out and then on as an Automatic Locking Retractor (ALR) till it is retracted fully.
ALR: Automatically locks when the webbing is pulled out from the retractor and allowed to retract even a little.
Then the webbing can not be pulled out any further, unless it is wound all the way back into the retractor, which
releases the lock and allows the webbing to be pulled out.
Driver and front passenger side air bags
The driver and front passenger side air bags are components of the air bag system. In occurrence of a front collision
with an impact larger than a certain set value, they are activated by the ignition signal from SDM to supplement
protection offered by the driver and front passenger seat belts.

the driver air bag (inflator) module is deployed from the center of the steering column

the passenger air bag (inflator) module from the top of the instrument panel in front of the front passenger seat

rized SUZUKI dealer. Refer to ªAir Bag System Components and Wiring Location Viewº under ªGener-
al Descriptionº in air bag system section in order to confirm whether you are performing service on
or near the air bag system components or wiring. Please observe all WARNINGS and ªService Precau-
tionsº under ªOn-Vehicle Serviceº in air bag system section before performing service on or around
the air bag system components or wiring. Failure to follow WARNINGS could result in unintentional
activation of the system or could render the system inoperative. Either of these two conditions may
result in severe injury.

Technical service work must be started at least 90 seconds after the ignition switch is turned to the
ªLOCKº position and the negative cable is disconnected from the battery. Otherwise, the system may
be activated by reserve energy in the Sensing and Diagnostic Module (SDM).
CAUTION:
When fasteners are removed, always reinstall them at the same location from which they were re-
moved. If a fastener needs to be replaced, use the correct part number fastener for that application. If
the correct part number fastener is not available, a fastener of equal size and strength (or stronger) may
be used. Fasteners that are not reused, and those requiring thread-locking compound, will be called
out. The correct torque value must be used when installing fasteners that require it. If the above proce-
dures are not followed, parts or system damage could result.

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.

WARNING:

Service on or around the air bag system components or wiring must be performed only by an autho-
rized SUZUKI dealer. Please observe all WARNINGS and ªService Precautionsº under ªOn-Vehicle
Serviceº in this section before performing service on or around the air bag system components or
wiring. Failure to follow WARNINGS could result in unintended activation of the system or could ren-
der the system inoperative. Either of these two conditions may result in severe injury.

The procedures in this section must be followed in the order listed to disable the air bag system tem-
porarily and prevent false diagnostic trouble codes from setting. Failure to follow procedures could
result in possible activation of the air bag system, personal injury or otherwise unneeded air bag sys-
tem repairs.

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.

AIR BAG WIRE HARNESS AND CONNECTORS
Air bag wire harness can be identified easily as it 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 all air bag system grounding points are clean and
grounds are securely fastened for optimum metal-to-metal con-
tact. Poor grounding can cause intermittent problems that are dif-
ficult to diagnose.
DISPOSAL
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 the air bag according to deployment
procedure described under ªAir Bag (Inflator) Modules Disposalº
and to activate the pretensioner according to activation procedure
described under ªSeat Belt Pretensioners Disposalº.
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.
