2001 SUZUKI GRAND VITARA Panel

AIR BAG SYSTEM 10B-3
General Description
With the air bag system which includes air bags for both the
driver’s and passenger’s sides as well as the seat belt pretension-
ers (if equipped), the sag of the seat belt is taken up (for seat belt
with pretensioner), the driver air bag (inflator) module is deployed
from the center of the steering column and the passenger air bag
(inflator) module from the top of the instrument panel in front of
the front passenger seat in occurrence of a front collision with an
impact larger than a certain set value to supplement protection
offered by the driver and front passenger seat belts.
The air bag system is designed to activate only in severe frontal
collisions. It is not designed to activate in rear impacts, side
impacts, rollovers, or minor frontal collisions, since it would offer
no protection in those types of accidents.

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.
