Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to ensure safety while working on the airbag system.
Allow the vehicle to sit for at least 10 minutes after disconnecting the battery to prevent accidental deployment of airbags.

2. Inspect and Replace Fuses

Locate the fuse box (usually under the dashboard or in the engine compartment).
Identify the airbag fuse using the diagram on the fuse box cover.
Use a fuse puller or needle-nose pliers to remove the fuse.
Inspect the fuse; replace it if it is blown with one of the same amperage.

3. Check Wiring and Connectors

Remove the driver's seat to access the airbag connectors underneath (if necessary).
Visually inspect all wiring for fraying, corrosion, or disconnections.
Reconnect any loose connectors and repair any damaged wiring using electrical tape or heat-shrink tubing.

4. Inspect the Seat Occupancy Sensor

If applicable, check the seat occupancy sensor under the passenger seat.
Ensure the connector is secured and the sensor is functioning correctly.
Replace the sensor if it is faulty.

5. Reconnect Battery and Reset System

Reconnect the negative battery terminal.
Use the OBD-II scanner to clear any error codes stored in the system.
Start the vehicle and check if the airbag warning light remains off after a short drive.
