Solution

1. Preparation

Gather tools and materials: OBD-II scanner, vehicle manual, and safety gear (gloves, goggles).
Ensure the vehicle is parked on a level surface with the engine off and keys removed from the ignition.

2. Connect OBD-II Scanner

Locate the OBD-II port, usually found under the dashboard near the driver’s seat.
Plug the OBD-II scanner into the port.
Turn the ignition to the "ON" position without starting the engine.

3. Read and Clear Codes

Follow the scanner instructions to access the airbag system.
Record any error codes displayed for reference.
Use the scanner to clear the codes from the airbag control module.

4. Inspect Airbag System Components

Visually check all airbag connections, especially at the seatbelt tensioners and airbag modules.
If any connections are loose or damaged, reconnect or replace them as necessary.

5. Test and Verify

Reconnect the vehicle battery if it was disconnected during inspection.
Start the vehicle and check if the airbag light remains off.
If the light is still illuminated, further investigation may be necessary.
