Sub-steps:
1. Remove the lower dashboard panel and trim around the steering column using trim removal tools.
2. Locate the seatbelt connectors and inspect for any damage or looseness; reconnect or replace as necessary.
3. Look for the airbag module, typically located under the dashboard, and check for corrosion or loose connections. Secure or replace as needed.
4. Use a multimeter to test the resistance of the airbag circuits; ensure readings are within manufacturer specifications.

3. Reconnect Battery and Reset System

Sub-steps:
1. Reconnect the negative battery terminal securely.
2. Use the OBD-II scanner to clear any existing airbag fault codes.
3. Perform a system check to ensure all components are functioning correctly.

4. Final Inspection and Reassembly

Sub-steps:
1. Reassemble the lower dashboard panel and any trim pieces removed during the inspection.
2. Ensure all screws and fasteners are tightened to the manufacturer’s torque specifications.
3. Perform a visual inspection of the dashboard lights; ensure the airbag warning light is no longer illuminated.
