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.

terminal of SDM connector and body
ground with ignition switch ON.
Is it 8 V or more?Go to step 3.“RED” wire (between “AIR
BAG” fuse and SDM con-
nector) open “BLK/YEL”
wire (between ignition
switch and “AIR BAG”
fuse) open or short to
ground
3 1) Disconnect 16-pin connector from combina-
tion meter. Refer to COMBINATION

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).
