Solution

1. Preparation

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

2. Inspect Airbag System

Locate the airbag connectors under the driver's seat.
Carefully disconnect the connectors and inspect for any damage or corrosion.
Use a multimeter to check for continuity in the wiring if necessary.

3. Reset the Airbag System

If no issues are found with the connectors, reconnect them securely.
Reconnect the negative battery terminal.
Use the OBD-II scanner to clear any stored airbag codes:
- Plug the scanner into the OBD-II port.
- Turn the ignition to the "ON" position (do not start the engine).
- Follow scanner prompts to clear the DTCs from the airbag system.

4. Test the System

Start the engine and observe the airbag light.
If the light turns off after a few seconds, the reset was successful.
