mality is found, be sure to replace it with new one as an assembly.
Be sure to read “SERVICE PRECAUTIONS”, before starting to work and observe every precaution
during work. Neglecting them may result in personal injury or unactivation of the seat belt preten-
sioner when necessary.

3. Retractor assembly 6. Retractor assembly upper mounting bolt
: After tightening lower bolt, tightening upper bolt

10-6 RESTRAINT SYSTEM
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.
4) Disconnect Yellow connector for seat belt pretensioner.
a) Release locking of lock lever.
b) After unlocked, disconnect to connector.
5) Remove front seat belts from the vehicle.
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.

10-8 RESTRAINT SYSTEM

Check the rear seat belt in the same way as “INSPECTION” of “FRONT SEAT BELT”.
INSTALLATION
Install the rear seat belt observing the same precautions as “INSTALLATION” of “FRONT SEAT BELT”. WARNING:
Be sure to read “SERVICE PRECAUTIONS” before starting to work and observe every precaution dur-
ing work.

Service on or around the air bag system components or wiring must be performed only by an
authorized SUZUKI dealer. Please observe all WARNINGS and “Service Precautions” under “On-
Vehicle Service” in this section before performing service on or around the air bag system compo-
nents or wiring. Failure to follow WARNINGS could result in unintended activation of the system or
could render 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
temporarily 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 system repairs.
CAUTION:
When fasteners are removed, always reinstall them at the same location from which they were
removed. 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
conditions are not followed, parts or system damage could result.

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 pretension-
ers (if equipped), the sag of the seat belt is taken up (for seat belt
with pretensioner), the driver air bag (inflator) 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
collisions. It is not designed to activate in rear impacts, side
impacts, rollovers, or minor frontal collisions, since it would offer
no protection in those types of accidents.

DIAGNOSIS
DIAGNOSTIC TROUBLE CODE (DTC)
The AIR BAG DIAGNOSTIC SYSTEM CHECK must always be the starting point of any air bag system diagno-
sis. The AIR BAG DIAGNOSTIC SYSTEM CHECK checks for proper “AIR BAG” warning lamp operation and
checks for air bag diagnostic trouble codes (DTCs) using on-board diagnosis function or SUZUKI scan tool.
USE OF SPECIAL TOOL
You should be familiar with the tools listed in this section under the heading SPECIAL TOOLS. You should be
able to measure voltage and resistance. You should be familiar with proper use of a scan tool such as Air Bag
Driver/Passenger Load Tool, Connector Test Adapter Kit and the Digital Multimeter.
Special tool
(A) : 09932-76010 (Connector Test Adapter Kit)
This must be used whenever a diagnostic procedure requests
checking or probing a terminal.
Using the appropriate adapter in the special tool will ensure that
no damage to the terminal will occur from the multimeter probe,
such as spreading or bending. TERMINAL CIRCUIT TERMINAL CIRCUIT

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 equip-
ment 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.
