Solution

1. Preparation

Gather necessary tools: OBD-II scanner, socket set, and safety glasses.
Ensure the vehicle is parked on a flat surface with the ignition off.
Disconnect the negative battery terminal and wait at least 10 minutes to allow the system to reset.

2. Use OBD-II Scanner

Reconnect the negative battery terminal.
Turn the ignition key to the "ON" position without starting the engine.
Connect the OBD-II scanner to the vehicle’s diagnostic port (usually located under the dashboard).
Follow the scanner instructions to read and clear the airbag codes.

3. Inspect Airbag Components

Check the connectors under the front seats and the steering wheel for proper connection.
If any connectors are loose or corroded, firmly reconnect or clean them as necessary.
Look for any signs of deployment or damage to the airbags.

4. Check Fuses

Locate the fuse box (usually under the dashboard or in the engine compartment).
Identify the airbag fuse using the diagram on the cover or in the owner’s manual.
Inspect the fuse and replace it if it is blown.
