Solution

1. Preparation

Gather necessary tools: OBD-II scanner, multimeter, socket set, and a torque wrench.
Ensure the vehicle is parked on a level surface and the ignition is off.

2. Scan for Error Codes

Connect the OBD-II scanner to the vehicle’s diagnostic port.
Turn the ignition to the ON position (do not start the engine).
Retrieve and record any error codes that appear related to the airbag system.

3. Inspect Fuses

Locate the fuse box (usually under the dashboard or in the engine compartment).
Identify the airbag system fuse and visually inspect it.
Replace any blown fuses with new ones of the same amperage.

4. Inspect Connectors

Disconnect the battery (negative terminal first) to prevent accidental airbag deployment.
Remove seat covers if needed to access airbag connectors under the seats.
Check for secure connections and any signs of corrosion. Clean or repair as necessary.
Reconnect the battery.

5. Check Seatbelt Buckle Switches

Test the seatbelt buckle switches with a multimeter to ensure they are functioning properly.
Replace faulty switches if they do not show continuity when engaged.

6. Reset the Airbag System

After making any necessary repairs, reconnect the battery.
Use the OBD-II scanner to clear any stored error codes.
Turn the ignition ON and check if the airbag light remains illuminated.
