Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative terminal of the battery and allow a few minutes for the system to discharge.
Ensure the vehicle is on a flat surface and secured with wheel chocks.

2. Retrieve and Clear Error Codes

Connect the OBD-II scanner to the vehicle's diagnostic port.
Retrieve any stored trouble codes related to the airbag system.
Note the codes for reference, then clear them to see if the light reappears after a test drive.

3. Inspect Wiring and Connectors

Remove the lower steering column cover to access the airbag wiring.
Visually inspect all connectors leading to the airbag control module and sensors for corrosion or damage.
Re-seat any loose connectors and repair any damaged wiring using electrical tape or heat-shrink tubing.

4. Test Airbag Components

Use a multimeter to test the resistance of the airbag circuits and ensure they are within specification.
Check the seatbelt pretensioners for proper operation and replace if faulty.

5. Reassemble and Test

Reattach all connectors and wiring properly.
Reinstall the steering column cover.
Reconnect the negative battery terminal.
Start the vehicle and check for the airbag light; perform a test drive to verify that the warning light does not reappear.
