Solution

1. Preparation

Gather necessary tools: OBD-II scanner, vehicle manual, and safety equipment (e.g., gloves).
Ensure the vehicle is parked on a level surface with the ignition off.

2. Connect OBD-II Scanner

Locate the OBD-II port under the dashboard on the driver's side.
Connect the OBD-II scanner to the port and turn the ignition key to the "ON" position without starting the engine.

3. Read and Clear Fault Codes

Follow the scanner's menu to read stored fault codes.
Make a note of the codes for reference.
Use the scanner's function to clear the codes and reset the airbag light.

4. Check Airbag System

If the light does not turn off, visually inspect airbag components such as the steering wheel airbag, passenger airbag, and side airbags for any signs of damage.
Reconnect any loose connectors or wires associated with the airbag system.

5. Recheck Fault Codes

After the inspection and any necessary reconnections, repeat the process to read fault codes.
Confirm that no new codes have appeared and the airbag light is off.
