Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, multimeter, safety gloves.
Disconnect the vehicle battery and allow it to sit for about 10 minutes to discharge any residual power before working on the airbag system.

2. Inspect and Replace Fuses

Locate the fuse box (refer to the owner’s manual for the exact location).
Remove the fuse panel cover and locate the airbag fuse.
Use the multimeter to test the fuse for continuity; replace if blown with a fuse of the same amperage.

3. Check Wiring and Connectors

Visually inspect wiring harnesses connected to the airbag system, including under the seats and in the steering wheel.
Look for frayed wires, loose connections, or corrosion.
Reconnect any loose connectors and repair any damaged wiring as necessary.

4. Seat Sensor Inspection

Check the seat occupancy sensor connectors underneath the front seats.
If a sensor is faulty, consider replacing it according to the manufacturer's specifications.

5. Clear Trouble Codes

Reconnect the battery.
Use the OBD-II scanner to clear any trouble codes.
Start the vehicle and observe if the airbag light remains illuminated.
