Solution

1. Preparation

Gather necessary tools: OBD-II scanner, socket set, and multimeter.
Ensure the vehicle is parked on a level surface with the ignition turned off.
Disconnect the negative battery terminal to prevent accidental deployment of airbags.

2. Retrieve and Clear Codes

Reconnect the battery terminal.
Plug the OBD-II scanner into the vehicle's diagnostic port located under the dashboard.
Turn the ignition key to the "ON" position without starting the engine.
Follow the scanner prompts to retrieve any airbag-related diagnostic trouble codes (DTCs).
If codes are present, note them for further inspection. Clear the codes using the scanner.

3. Check for Faulty Components

If the airbag light returns after clearing codes, inspect the airbag connectors and wiring harnesses under the seats and dashboard.
Use a multimeter to test continuity in the airbag circuit, ensuring there are no breaks or shorts.
Replace any damaged connectors or wiring as necessary.

4. Final Verification

Reconnect the negative battery terminal.
Start the vehicle and check if the airbag light remains off.
Test drive the vehicle to monitor if the light re-illuminates during operation.
