CONNECTOR “Q06” (SDM connector)
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.

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.

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

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.)

NOTE:
When 2 or more codes are indicated, the lowest numbered code will appear first.
Current DTC and history DTC can be identified by lighting and flashing of “AIR BAG” warning lamp
as follows. However, if a multiple number of DTC’s are set an even one of them is a current DTC,
“AIR BAG” warning lamp remains on after ignition switch is turned ON. Therefore, it is not possible
to identify any of them as to whether it is a current one or a history one. (But use of SUZUKI scan
tool will make identification possible.)
Current DTC is set.
(Abnormality exists at present.)History DTC is set only.
(Faulty condition occurred once
in the past but normal condition
is restored at present.)

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.
