WARNING:
For vehicles equipped with Supplemental Restraint (Air Bag) System with seat belt pretensioner:
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 air bag system section before performing service on or around the air bag sys-
tem 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.
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
procedures are not followed, parts or system damage could result.

ON-VEHICLE SERVICE
SERVICE PRECAUTIONS
SERVICE AND DIAGNOSIS
Before servicing or replacing seat belts, refer to following precautionary items.
Seat belts should be normal relative to strap retractor and buckle portions.
Keep sharp edges and damaging objects away from belts.
Avoid bending or damaging any portion of belt buckle or latch plate.
Do not bleach or dye belt webbing. (Use only mild soap and lukewarm water to clean it.)
When installing a seat belt anchor bolt, it should be tightened by hand at first to prevent cross-threading and
then to specified torque.
Do not attempt any repairs on retractor mechanisms or retractor covers. Replace defective assemblies with
new replacement parts.
Keep belts dry and clean at all times.
If there exist any parts in question, replace such parts.
Replace belts whose webbing is cut or otherwise damaged.
Do not put anything into trim panel opening which seat belt webbing passes through.
For Seat Belt with Pretensioner
Refer to “SERVICE AND DIAGNOSIS” of “SERVICE PRECAUTIONS” under “ON-VEHICLE SERVICE” in Sec-
tion 10B.
DISABLING AIR BAG SYSTEM
Refer to “DISABLING AIR BAG SYSTEM” of “SERVICE PRECAUTIONS” under “ON-VEHICLE SERVICE” in
Section 10B.
ENABLING AIR BAG SYSTEM
Refer to “ENABLING AIR BAG SYSTEM” of “SERVICE PRECAUTIONS” under “ON-VEHICLE SERVICE” in
Section 10B.
HANDLING AND STORAGE
Refer to “HANDLING AND STORAGE” of “SERVICE PRECAUTIONS” under “ON-VEHICLE SERVICE” in Sec-
tion 10B.
DISPOSAL
Refer to “DISPOSAL” of “SERVICE PRECAUTIONS” under “ON-VEHICLE SERVICE” in Section 10B. WARNING:
If replacing seat belt is necessary, replace buckle and ELR (or webbing) together as a set. This is for
the reason of ensuring locking of tongue plate with buckle.
If these parts are replaced individually, such a locking condition may become unreliable. For this rea-
son, SUZUKI will supply only the spare buckle and ELR (or webbing) in a set part.
WARNING:
When performing service on or around air bag system components or air bag system wiring, disable
the air bag system. Refer to “DISABLING AIR BAG SYSTEM” of “SERVICE PRECAUTIONS” under
“ON-VEHICLE SERVICE” in Section 10B.
Failure to follow procedures could result in possible air bag activation, personal injury or unneeded
air bag system repairs.

INTERMITTENTS AND POOR CONNECTIONS
Most intermittents are caused by faulty electrical connections or
wiring. When a check for proper connection is requested in a
diagnostic flow table, perform careful check of suspect circuits for:
Poor mating of connector halves, or terminals not fully
seated in the connector body (backed out).
Dirt or corrosion on the terminals. The terminals must be
clean and free of any foreign material which could impede
proper terminal contact.
However, cleaning the terminal with a sand paper or the like
is prohibited.
Damaged connector body, exposing the terminals to mois-
ture and dirt, as well as not maintaining proper terminal ori-
entation with the component or mating connector.
Improperly formed or damaged terminals.
Check each connector terminal in problem circuits carefully
to ensure good contact tension by using the corresponding
mating terminal included in the connector test adapter kit
(special tool).
If contact tension is not enough, reform it to increase contact
tension or replace.
Special tool
(A) : 09932-76010 (Connector Test Adapter Kit)
Poor terminal-to-wire connection.
Check each wire harness in problem circuits for poor con-
nection by shaking it by hand lightly. If any abnormal condi-
tion is found, change the wire harness assembly or
component parts with new ones.
Wire insulation which is rubbed through, causing an intermit-
tent short as the bare area touches other wiring or parts of
the vehicle.
Wire broken inside the insulation. This condition could cause
a continuity check to show a good circuit, but if only 1 or 2
strands of a multi-strand-type wire are intact, resistance
could be far too high.
If any abnormality is found, repair or replace as a wire harness
assembly.

CAUTION:
Be sure to perform AIR BAG DIAGNOSTIC SYSTEM CHECK before starting diagnosis according to
flow table.
When measurement of resistance or voltage is required in this table, use a tester along with a cor-
rect terminal adapter from special tool (Connector test adapter kit).
When a check for proper connection is required, refer to INTERMITTENT AND POOR CONNEC-
TIONS in this section.
If there is open circuit in the air bag wire harness, connector or terminal is found damaged, replace
the wire harness, connector and terminal as an assembly.
