NOTE:
Upon completion of inspection and repair work, perform following items.
Reconnect all air bag system components, ensure all components are properly mounted.
Repeat AIR BAG DIAGNOSTIC SYSTEM CHECK to confirm that the trouble has been corrected.
Step Action Yes No
1 1) Set parking brake.
2) Note combination meter when ignition
switch is turned ON.
Does the “BRAKE” indicator (warning lamp)
come ON?Go to step 2.“BLK/WHT” wire, “IG
METER” fuse or J/B
(between ignition switch
and combination meter)
open or short to ground
2 1) With ignition switch OFF, disconnect SDM.
2) Check electrical connection check mecha-
nism.
Is it in good condition?Go to step 3. Repair electrical connec-
tion check mechanism.
3 1) Disconnect SDM.
2) Check proper connection to SDM at termi-
nal “Q06-2”.
3) If OK then check voltage from “Q06-2” ter-
minal of SDM connector to body ground
with ignition switch ON.
Is it 8 V or more?Substitute a known-good
SDM and recheck.Go to step 4.
4 1) Remove combination meter. Refer to COM-
BINATION METER in SECTION 8.
2) Check proper connection to combination
meter at “YEL/BLK” terminal for “AIR BAG”
warning lamp and to SDM at terminal “Q06-
2”.
3) If OK then check resistance between “YEL/
BLK” wire terminal of combination meter
connector (16-pin connector) and “Q06-2”
terminal of SDM connector.
Is resistance 1 Ω or less?Go to step 5. Repair high resistance or
open in “YEL/BLK” wire
circuit (between combina-
tion meter and SDM).

6 1) Remove and inspect “AIR BAG” bulb.
Is bulb good?Substitute a known-good
combination meter and
recheck.Replace bulb. Step Action Yes No

TABLE TEST DESCRIPTION
STEP 1 : An improper connection to the data link connector (DLC) will prevent communications from being
established.
STEP 2 : This test checks whether it is possible to communicate with other control module.
STEP 3 : This test checks for an open in “BLU” circuit (in air bag harness).

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.
Step Action Yes No
1 1) Make sure that SUZUKI scan tool is free from malfunc-
tion and correct cartridge for air bag system is used.
2) Ignition switch OFF.
3) Check proper connection of SUZUKI scan tool to DLC.
Is connection in good condition?Go to step 2. Properly connect SUZUKI
scan tool to DLC.
