1) Disconnect combination meter connector “G28” referring 

to “Combination Meter Removal and Installation in 
Section 9C”.

2) Check proper connection to combination meter at “YEL/

BLK” terminal for “AIR BAG” warning lamp and to SDM 
at terminal “G47-18” or “G46-7”.

3) If OK, then check resistance between “YEL/BLK” wire 

terminal of combination meter connector “G28” and 
“G47-18” terminal [A] or “G46-7” terminal [B] of SDM 
connector.

Special tool

 or less?

Substitute a known-
good SDM and recheck. 
If “AIR BAG” warning 
lamp remain lighting, 
replace combination 
meter.

“YEL/BLK” wire 
(between combination

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.

Check and correct the 
following possible 
cause. 

• Open circuit in 

“BLK/YEL” or “PPL/
RED” wire. 

• Short 

circuit between “BLK/
YEL” or “PPL/RED” and 
ground. 

• “METER” fuse 

blown.

2

1) Disconnect SDM connector “G46” or “G47”.
2) Note combination meter when ignition switch is turned 

ON.

Does the “AIR BAG” warning lamp come ON?

Substitute a known-
good SDM and recheck.

“YEL/BLK” circuit 
shorted to power circuit. 
If OK, replace 
combination meter.

Yes

No

1

Inspect connection between diagnostic switch terminal on 
“AIR BAG” monitor coupler and body ground with service 
wire.

Are they connected securely with service wire?

Go to Step 2.

Properly connect 
diagnostic switch 
terminal on “AIR BAG” 
monitor coupler and 
body ground with 
service wire.

2

1) Disconnect SDM connector from SDM.
2) Check for proper connection at “PPL” wire (“G47-14” 

terminal or “G46-12” terminal of SDM connector and 
“G34-2” terminal of “AIR BAG” monitor coupler (1)) 
terminals.

3) If OK, then measure resistance between “G47-14” 

terminal [A] or “G46-12” terminal [B] and “G34-2” 
terminal.

Special tool
(A):  09932–76010 

Is resistance 1 

Ω

 or more?

Check “PPL” wire 
terminals. If OK, repair
