WARNING:
For vehicles equipped with Supplemental Restraint (Air Bag) System:
Service on and around the air bag system components or wiring must be performed only by an
authorized SUZUKI dealer. Refer to “Air Bag System Components and Wiring Location View” under
“General Description” in air bag system section in order to confirm whether you are performing ser-
vice on or near the air bag system components or wiring. Please observe all WARNINGS and “Ser-
vice Precautions” under “On-Vehicle Service” 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
“LOCK” 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).
When body servicing, if shock may be applied to air bag system component parts, remove those
parts beforehand. (Refer to Section 10B.)
NOTE:
For the descriptions (items) not found in this section, refer to the same section of the Service Man-
ual mentioned in the FOREWORD of this manual.
Fasteners are important attaching parts in that they could affect the performance of vital compo-
nents and systems, and/or could result in major repair expense. They must be replaced with one of
the same part number of with an equivalent part if replacement becomes necessary.
Do not use a replacement part of lesser quality or substitute a design. Torque values must be used
as specified during reassembly to assure proper retention of these parts.

General Description
SEAT BELT WITH ELR
The seat belt with Emergency Locking Retractor (ELR) is designed so that it locks immediately (to prevent the
webbing 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.
SEAT BELT WITH PRETENSIONER (IF EQUIPPED)
The seat belt with ELR and a pretensioner has a pretensioner mechanism which operates in linkage with the air
bag in addition to the above described ELR. The pretensioner takes up the sag of the seat belt in occurrence of
a front collision with an impact larger than a certain set value, thereby enhancing restraint performance.
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 col-
lision with an impact larger than a certain set value, they are activated by the ignition signal from SDM to supple-
ment 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
For more information, refer to Section 10B “Air Bag System”.

WARNING:
For vehicles equipped with Supplemental Restraint (Air Bag) System:
Service on and around the air bag system components or wiring must be performed only by an

conditions may result in severe injury.
Technical service work must be started at least 90 seconds after the ignition switch is turned to the
“LOCK” 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
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.

AIR BAG SYSTEM 10B-9
Air Bag Diagnostic System Check
The diagnostic procedures used in this section are designed to find and repair air bag system malfunctions.
To get the best results, it is important to use the diagnostic flow tables and follow the sequence listed below.
1) Perform the AIR BAG DIAGNOSTIC SYSTEM CHECK FLOW TABLE.
(The AIR BAG DIAGNOSTIC SYSTEM CHECK FLOW TABLE must be the starting point of any air bag sys-
tem diagnosis.
The AIR BAG DIAGNOSTIC SYSTEM CHECK FLOW TABLE checks for proper “AIR BAG” warning lamp
operation through “AIR BAG” warning lamp and whether air bag diagnostic trouble codes exist.)
2) Refer to the proper diagnostic table as directed by the AIR BAG DIAGNOSTIC SYSTEM CHECK FLOW
TABLE.
(The AIR BAG DIAGNOSTIC SYSTEM CHECK FLOW TABLE will lead you to the correct table to diagnose
any air bag system malfunctions. Bypassing these procedures may result in extended diagnostic time, incor-
rect diagnosis and incorrect parts replacement.)
3) Repeat the AIR BAG DIAGNOSTIC SYSTEM CHECK FLOW TABLE after any repair or diagnostic proce-
dures have been performed.
(Performing the AIR BAG DIAGNOSTIC SYSTEM CHECK FLOW TABLE after all repair or diagnostic pro-
cedures will ensure that the repair has been made correctly and that no other malfunctions exist.)
FLOW TABLE TEST DESCRIPTION
STEP 1 : Check that “AIR BAG” warning lamp lights.
STEP 2 : Check that “AIR BAG” warning lamp lights.
STEP 3 : Check diagnosis switch circuit.
STEP 4 : Check that “AIR BAG” warning lamp flashes 6 times after ignition switch is turned ON.
STEP 6 : Check that history codes are in SDM memory. (using SUZUKI scan tool)
STEP 7 : Check that history codes are in SDM memory. (using monitor coupler)
STEP 9 : Check that current code is in SDM memory. (using SUZUKI scan tool)
STEP 10 : Check that current code is in SDM memory. (using monitor coupler)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.
CAUTION:
The order in which diagnostic trouble codes are diagnosed is very important. Failure to diagnose the
diagnostic trouble codes in the order specified may result in extended diagnostic time, incorrect diag-
nosis and incorrect parts replacement.

AIR BAG SYSTEM 10B-11
DTC Check
Using SUZUKI scan tool
1) Turn ignition switch to OFF position.
2) After setting cartridge to SUZUKI scan tool, connect it to
data link connector (DLC) located on underside of instru-
ment panel at driver’s seat side.
Special tool
(A) : SUZUKI scan tool
3) Turn ignition switch to ON position.
4) Read DTC according to instructions displayed on SUZUKI
scan tool and print it or write it down. Refer to SUZUKI scan
tool operator’s manual for further details.
If communication between scan tool and SDM is not possi-
ble, proceed to Diagnostic Flow Table E (Serial data check
circuit).
5) After completing the check, turn ignition switch to OFF posi-
tion and disconnect SUZUKI scan tool from data link connec-
tor (DLC).
Not using SUZUKI scan tool
1) Check that malfunction indicator lamp (“AIR BAG” warning
lamp) comes ON when ignition switch is turned to ON posi-
tion.
If it does not come “ON”, proceed to Diagnostic Flow Table B
(“AIR BAG” warning lamp circuit).
2) Using service wire, ground diagnosis switch terminal in mon-
itor coupler.
3) Read DTC from flashing pattern of malfunction indicator
lamp (“AIR BAG” warning lamp). (Refer to DTC TABLE.)
If lamp does not indicate DTC, proceed to Diagnostic Flow
Table D (Diagnosis switch terminal circuit check).
4) After completing the check, turn ignition switch to OFF posi-
tion and disconnect service wire from “AIR BAG” monitor
coupler.
