NOTE
Upon completion of inspection and repair work, perform the following items.
• Reconnect all air bag system components and ensure all components are properly mounted.
• Repeat “Air Bag Diagnostic System Check” to confirm that the trouble has been corrected.

“AIR BAG” Warning Right Does Not Come ONS7RS0B8204008
Wiring Diagram6 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 right and to SDM at
terminal “L29-2”.
3) If OK, then check resistance between “YEL/BLK” wire terminal of combination meter connector “G28” and
“L29-2” terminal of SDM connector.
Special tool
(A): 09932-76010
Is resistance 1
Ω or less? Substitute a known-
good SDM and recheck.
If “AIR BAG” warning
right remain lighting,
replace combination
meter.
“YEL/BLK” wire
(between combination
meter and SDM
connector) open or
short to ground.
