Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to prevent accidental airbag deployment.
Allow the vehicle to sit for at least 10 minutes to ensure system discharge.

2. Inspect Airbag Wiring and Connectors

Locate the airbag connectors under the seats and dashboard.
Carefully disconnect each connector and check for bent pins or corrosion.
Clean any corrosion with electrical contact cleaner and reconnect securely.

3. Check Seatbelt Switches

Remove the seat covers or access panels to expose the seatbelt buckle switches.
Test the switches for continuity using a multimeter.
Replace any faulty switches as necessary.

4. Inspect Airbag Control Module

Locate the airbag control module, typically found under the center console or near the driver's seat.
Visually inspect the module for any signs of damage or loose connections.
Ensure all harnesses connected to the module are secure.

5. Clear Fault Codes

Reconnect the negative battery terminal.
Use the OBD-II scanner to clear any stored airbag fault codes.
Start the vehicle and observe if the airbag warning light remains off.
