The adapter will also give an idea of whether contact tension is
sufficient, helping to find an open or intermittent open due to poor
terminal contact.
Special tool
(B) : 09932-75010 (Air Bag Driver/Passenger Load Tool)
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
(inflator) module deployment.
The load tool has three connectors attached to its case which are
electrically functional and serve as resistive load substitutions.
No more than two connectors are used at any time.
One of connectors (“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.
Another connector (“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.
The third connector (“PASSENGER INFLATOR”) is not used.
By substituting the resistance of the load tool when called for, a
determination can be made as to whether an inflator circuit com-
ponent is causing system malfunction and which component is
causing the malfunction.
The load tool should be used only when specifically called for in
the diagnostic procedures.
1. Connector for contact coil and driver air bag (inflator) module
(Located near the base of the steering column)
2. Connector for driver, passenger air bag (inflator) module and driver and
passenger seat belt pretensioners
3. Not used

ON-VEHICLE SERVICE
SERVICE PRECAUTIONS
SERVICE AND DIAGNOSIS
WARNING/CAUTION labels are attached on each part of air bag system components (SDM, air bag (inflator)
modules and seat belt pretensioners). Be sure to follow the instructions.
Many of service procedures require disconnection of “AIR BAG” fuse and air bag (inflator) module(s) (driver
and passenger) from initiator circuit to avoid an accidental deployment.
Do not apply power to the air bag system unless all components are connected or a diagnostic chart
requests it, as this will set a diagnostic trouble code (DTC).
The “AIR BAG DIAGNOSTIC SYSTEM CHECK” must be the starting point of any air bag diagnostics. The
“AIR BAG DIAGNOSTIC SYSTEM CHECK” will verify proper “AIR BAG” warning lamp operation and will
lead you to the correct table to diagnose any air bag malfunctions. Bypassing these procedures may result
in extended diagnostic time, incorrect diagnosis, and incorrect parts replacements.
Never use air bag component parts from another vehicle.
If the vehicle will be exposed to temperatures over 93°C (200°F) (for example, during a paint baking pro-
cess), remove the air bag system components beforehand to avoid component damage or unintended sys-
tem activation.
When handling the air bag (inflator) modules (driver and passenger), seat belt pretensioners (driver and
passenger) or SDM, be careful not to drop it or apply an impact to it. If an excessive impact was applied
(e.g., SDM is dropped, air bag (inflator) module is dropped from a height of 90 cm (3 ft) or more, seat belt
pretensioner (retractor assembly) is dropped from a height of 30 cm (1 ft) or more), never attempt disassem-
bly or repair but replace it with a new one.
When using electric welding, be sure to disconnect air bag (inflator) module connectors (driver and passen-
ger) and seat belt pretensioner connectors (driver and passenger) respectively.
When applying paint around the air bag system related parts, use care so that the harness or connector will
not be exposed to the paint mist.
Never expose air bag system component parts directly to hot air (drying or baking the vehicle after painting)
or flames. WARNING:
If the air bag system and another vehicle system both need repair, Suzuki recommends that the air
bag system be repaired first, to help avoid unintended air bag system activation.
Do not modify the steering wheel, dashboard or any other on or around air bag system compo-
nents. Modifications can adversely affect air bag system performance and lead to injury.
Failure to follow procedures could result in possible air bag system activation, personal injury or
unneeded air bag system repairs.
WARNING:
When performing service on or around air bag system components or air bag wiring, follow the proce-
dures listed in the following pages to temporarily disable the air bag system.
Failure to follow procedures could result in possible air bag system activation, personal injury or
unneeded air bag system repairs.

–Check wire harness and connector for damage or tight-
ness.
If any faulty condition is found in above checks, replace faulty
part.
Contact coil and combination switch assembly
–Check wire harness and connectors for damage or tight-
ness.

cause in itself. (There is a gap between SDM and SDM
plate, or it cannot be fixed securely.)
–Check that connector or lead wire of SDM has a scorching,
melting or damage.
–Check SDM connector and terminals for tightness.
–Check SDM sets a diagnostic trouble code (Refer to “DTC
CHECK”.) and the diagnostic table leads to a malfunction-
ing SDM.
If any faulty condition is found in above checks, replace.
Instrument panel member and reinforcement
–Check for any distortion, bending, cracking or other dam-
age.
If any faulty condition is found in above checks, replace.
Passenger air bag (inflator) module
–Check for dents, cracks, damage or fitness.
–Check trim cover for cracks or deformities.
–Check harness and connector for damage or tightness.
If any faulty condition is found in above checks, replace.
