DIAGNOSTIC TROUBLE CODE (DTC) CHECK
[Using SUZUKI scan tool]
1) Turn ignition switch OFF.
2) After setting cartridge to Tech 1, connect it to data link connector
(DLC) located on underside of instrument panel at driver's seat
side.
Special Tool
(A): 09931-76011 (Tech 1)
(B): Mass storage cartridge
(C): 09931-76030
3) Turn ignition switch ON.
4) Read DTC according to instructions displayed on Tech 1 and
print it or write it down. Refer to Tech 1 operator's manual for fur-
ther details.
5) After completing the check, turn ignition switch OFF and discon-
nect Tech 1 from data link connector (DLC).
[Not using SUZUKI scan tool]
1) Check that malfunction indicator lamp (ªAIR BAGº warning
lamp) comes ON when ignition switch is turned ON.
If it does not come ªONº, proceed to ªTable Bº on p.10B-18.
2) Using service wire, ground diagnosis switch terminal in monitor
coupler.
3) Read DTC from flashing pattern of malfunction indicator lamp
(ªAIR BAGº warning lamp). (Refer to ªDiagnostic Trouble Code
Tableº on p.10B-14 and 10B-15.)
4) After completing the check, turn ignition switch OFF and discon-
nect service wire from ªAIR BAGº monitor coupler.

2) Connect Tech 1 to data link connector (DLC) in the same manner
as when making this connection for DTC check.
Special Tool
(A): 09931-76011 (Tech 1)
(B): Mass storage cartridge
(C): 09931-76030
3) Turn ignition switch ON.
4) Erase DTC according to instructions displayed on Tech 1.
Refer to Tech 1 operator's manual for further details.
5) After completing the check, turn ignition switch OFF and discon-
nect Tech 1 from data link connector (DLC).
6) Perform ªDiagnosis Trouble Code (DTC) Checkº and confirm
that normal DTC (NO CODES) is displayed and not malfunction
DTC.
NOTE:
If DTC 51 or DTC 71 is stored in SDM, it is not possible to
clear DTC.
[Not using SUZUKI scan tool]
1) Turn ignition switch ON and wait about 6 seconds or more.
2) Using service wire, repeat shorting and opening between diag-
nosis switch terminal and ground terminal on ªAIR BAGº monitor
coupler 5 times at about 1 second intervals.
3) Perform ªDiagnosis Trouble Code (DTC) Checkº and confirm
that normal DTC (DTC 12) is displayed and not malfunction
