Remove the driver's seat (if necessary) using a socket set, taking care not to damage the connectors underneath.
- Sub-steps:
  - Disconnect battery (as stated).
  - Remove the seat bolts and lift the seat out carefully.
Check the airbag harness connector and ensure it is securely connected.
Inspect for any frayed wires or corrosion.

3. Replace Faulty Components

If any blown fuses were found earlier, replace them with the correct amperage fuse.
If error codes indicated a faulty airbag module or sensor, replace the necessary component.
- Sub-steps:
  - Disconnect connectors and remove the faulty module following the manufacturer's repair manual.
  - Install the new module, ensuring all connectors are properly fitted.

4. Clear Error Codes

Reconnect the battery.
Use the OBD-II scanner to clear any error codes and reset the airbag system.
Verify that the airbag light turns off after clearing codes.

5. Reassemble and Test

Reinstall the driver's seat if it was removed.
Ensure all trim panels are properly reinstalled.
Test drive the vehicle to ensure the airbag light remains off.
