Solution

1. Preparation

Gather tools: OBD-II scanner, socket set, multimeter, and a flathead screwdriver.
Ensure the vehicle is parked on a level surface, and the ignition is turned off.
Disconnect the negative battery terminal to avoid accidental deployment of the airbags.

2. Retrieve and Address Error Codes

Connect the OBD-II scanner to the vehicle’s diagnostic port.
Turn the ignition to the "ON" position without starting the engine.
Retrieve any airbag-related error codes and note them for further troubleshooting.
Clear the codes and see if the airbag warning light returns after a restart.

3. Inspect Wiring and Connectors

Remove the seat cushion if necessary to access the wiring under the seats.
Visually inspect all connectors for corrosion or loose connections.
Use a multimeter to check for continuity in the wiring leading to the airbag system.
Repair or replace any damaged wires or connectors as needed.

4. Check and Replace Fuse

Locate the fuse box and identify the airbag fuse using the owner's manual.
Inspect the fuse for continuity; replace it with a new one if blown.
Reconnect the battery terminal and check if the warning light is still illuminated.

5. Test Seat Belt Sensors

Inspect the buckle sensors for proper operation by pressing and releasing the buckle while observing the dashboard indicator.
If faulty, replace the seat belt buckle assembly.
