Is it connected securely?
YES -
Go to Step 4.
NO -
Correct connector "G01" securely.

4.
Check for loose connection of SDM connector "G47" or "G46".

YES -
Go to Step 5.
NO -
Correct connector "G47" or "G46" securely.

5. Disconnect SDM connector "G47" or "G46".
Check proper connection to SDM at terminal "G47-16" or "G46-11".
If OK, then check voltage between "G47-16" terminal [A] or "G46-11" terminal [B] of SDM connector and body ground with ignition switch ON.

Is resistance 1 ohms or less?
YES -
Substitute a known-good SDM and recheck. If "AIR BAG" warning light remain lighting, replace combination meter.
NO -
"YEL/BLK" wire (between combination meters and SDM connector) open or short to ground.

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 Air Bag Diagnostic System Check:Except Advanced Air Bag
to confirm that the trouble has been corrected.
