“AIR BAG” Warning Light Does Not Come ONS6RW0D8204008
Wiring Diagram
Refer to ““AIR BAG” Warning Light Comes ON Steady”.
Troubleshooting
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.

Step Action Yes No
1Was “Air Bag Diagnostic System Check Flow” performed?Go to Step 2. Go to “Air Bag
Diagnostic System
Check Flow”.
2Combination meter power feed circuit check
1) Set parking brake.
2) Note combination meter when ignition switch is turned
ON.
Does the “BRAKE” indicator (warning light) come ON?Go to Step 3. Check combination
meter power and
ground circuit referring
to “C-1 Combination
Meter Circuit Diagram
(Meter) in Section 9A”.
3“AIR BAG” warning light circuit check
1) Disconnect SDM connector “L04”.
2) Note combination meter when ignition switch is turned
ON.
Does the “AIR BAG” warning light come ON?Substitute a known-
good SDM and recheck.Go to Step 4.
4“AIR BAG” warning light circuit check
1) Disconnect SDM connector “L04”.
2) With ignition switch turned ON, measure voltage
between “L04-02” terminal and body ground.
Special tool
(A): 09932–76010
Is measured voltage 0 V?Replace combination
meter.Repair “YEL/BLK”
circuit for short to power
circuit.
