Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, multimeter
Ensure the vehicle is parked on a flat surface with the ignition turned off.
Disconnect the vehicle battery for safety, allowing it to rest for at least 10 minutes to discharge any residual voltage.

2. Access the Airbag Control Module

Locate the airbag control module, usually under the driver's seat or in the center console.
Use a socket set to remove any panels or coverings obstructing access to the module.

3. Inspect and Connect

Visually inspect the airbag control module connectors for corrosion or damage.
Reconnect any loose or damaged connectors and ensure they click into place securely.

4. Reset the Airbag Light

Reconnect the vehicle battery.
Use the OBD-II scanner to connect to the vehicle's onboard system.
Navigate to the airbag section on the scanner and select the option to clear fault codes.
Confirm the reset process and wait for the scanner to finish.

5. Verify Operation

Start the vehicle and observe the dashboard for the airbag light.
If the airbag light remains off, the system has been successfully reset.
