If codes indicate a specific fault (e.g., a faulty sensor), replace or repair the identified component.
For seatbelt issues, ensure that all seatbelt connections are secure and functioning properly.
If a blown fuse is identified, replace it with the correct amperage rating as specified in the owner's manual.

4. Clear Codes

With the issue resolved or addressed, re-connect the OBD-II scanner.
Follow the scanner’s instructions to clear the error codes from the airbag system.
Disconnect the scanner once the codes have been cleared.

Reconnect the negative battery terminal.
Turn on the ignition and check to see if the airbag warning light has turned off.
Start the vehicle and perform a quick test drive to ensure the light remains off.
