Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface, and the ignition is off.
Disconnect the vehicle's battery and wait at least 10 minutes to avoid accidental airbag deployment.

2. Scan for Error Codes

Connect the OBD-II scanner to the vehicle's diagnostic port.
Turn on the ignition (without starting the engine) and scan for error codes.
Note down any codes and refer to a service manual for specific error code definitions.

3. Inspect Wiring and Connectors

Remove the front seat(s) if necessary for better access.
Visually inspect wiring and connectors for any signs of wear, corrosion, or loose connections.
Reconnect or replace any damaged connectors or wiring.

4. Check Airbag Fuse

Locate the fuse box and identify the airbag fuse using the diagram on the cover.
Use a fuse puller or pliers to remove the fuse and visually inspect it.
Replace the fuse with one of the same amperage if it is blown.

5. Test Seat Belt Sensors

Inspect the seat belt sensors for any foreign objects or damage.
Disconnect and reconnect the seat belt sensor connectors to ensure a good connection.
Replace faulty sensors if necessary.

6. Reconnect Battery and Clear Codes

Reconnect the vehicle's battery.
Use the OBD-II scanner to clear any stored error codes.
Turn on the ignition and check if the airbag light remains off.
