1. Locate the fuse box, refer to the owner's manual for the exact location.
2. Remove the fuse cover and identify the airbag fuse using the diagram.
3. Use a multimeter to test the fuse for continuity. If blown, replace it with a new fuse of the same amperage.
4. Reinstall the fuse cover and turn the ignition on to check if the airbag light is still illuminated.

3. Inspect Airbag Connectors

Sub-steps:
1. Disconnect the battery by removing the negative terminal to ensure safety.
2. Remove the seats if necessary to access the airbag connectors.
3. Inspect connectors for corrosion, loose connections, or broken pins. Clean and secure any loose connections.
4. Reconnect the connectors and reinstall the seats if removed. Reconnect the battery.

4. Scan for DTCs and Clear Codes

Sub-steps:
1. Using the OBD-II scanner, plug it into the vehicle's diagnostic port.
2. Access the airbag system and read any stored DTCs.
3. Note any codes and research them for specific repair procedures if necessary.
4. Clear the codes using the scanner and check if the airbag light remains off after a test drive.
