Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface with the ignition turned off.
Disconnect the negative battery terminal to prevent accidental deployment of airbags.

2. Scan and Clear Fault Codes

Connect the OBD-II scanner to the vehicle's diagnostic port.
Retrieve and note all airbag-related fault codes.
Clear the fault codes from the system and observe if they reappear after a short drive.

3. Inspect Wiring and Connectors

Remove the front seats if necessary to access the wiring harnesses.
Visually inspect all connectors for corrosion or damage, particularly under the seats and steering column.
Reconnect any loose connectors securely and repair any damaged wires.

4. Check Seat Occupancy Sensor

If applicable, remove the passenger seat to access the seat occupancy sensor.
Inspect the sensor and its connections for wear or damage.
Replace the sensor if it is found to be faulty or if the connections are compromised.

5. Reassemble and Test

Reinstall any components removed during inspection.
Reconnect the negative battery terminal.
Start the vehicle and check if the airbag light remains illuminated.
