Solution

1. Preparation

Gather necessary tools: OBD-II scanner, socket set, and possibly a multimeter.
Ensure the vehicle is in a safe, well-ventilated area and the engine is turned off.
Disconnect the vehicle's battery, starting with the negative terminal to prevent any electrical shorts.

Connect the OBD-II scanner to the vehicle's diagnostic port.
Turn the ignition to the "On" position without starting the engine.
Access the airbag module using the scanner and retrieve any stored fault codes.
Follow the scanner's prompts to clear any fault codes and reset the airbag light.

3. Reconnect Battery

After clearing the codes, reconnect the negative battery terminal.
Ensure the connection is secure and there are no loose wires.
