DIAGNOSTIC TROUBLE CODE (DTC) CLEARANCE
[Using SUZUKI scan tool]
1) Turn ignition switch OFF.
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
DTC.
NOTE:
If DTC 51 or DTC 71 is stored in SDM, it is not possible to
clear DTC.
