Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the vehicle’s battery and ensure it has been off for at least 10 minutes to avoid accidental airbag deployment.
Tools required: OBD-II scanner, socket set, multimeter, screwdrivers.

2. Address Fault Codes

Connect the OBD-II scanner and retrieve stored airbag fault codes.
Document the codes and research specific issues related to them.
Clear the codes and see if they return after a test drive.

3. Inspect Airbag System Components

Remove the driver's side airbag cover using a screwdriver or socket.
Carefully disconnect the airbag connector. Inspect for corrosion or damage.
If the airbag light persists, inspect the airbag control module located under the dashboard.
Check for loose or damaged wiring in the airbag system.

4. Repair or Replace Components

If any damaged components are identified (e.g., connectors, control module), replace them with OEM parts.
Ensure all connections are secure and clean before reassembly.
Reinstall the airbag cover and reconnect the battery.

5. Final Testing

Reconnect the battery and turn on the ignition to check if the airbag light remains off.
Perform a test drive to verify the airbag system's functionality.
