Solution

1. Preparation

Gather tools such as an OBD-II scanner, multimeter, socket set, and a torque wrench.
Disconnect the negative battery terminal to prevent accidental airbag deployment.
Allow the vehicle to sit for at least 10 minutes after disconnecting the battery.

2. Retrieve and Analyze Error Codes

Use the OBD-II scanner to connect to the vehicle’s diagnostic port.
Record any error codes related to the airbag system and refer to a service manual for their meanings.

3. Inspect Airbag System Components

Check connectors under the seats and dashboard for loose or damaged wiring.
Inspect the airbag module and ensure all connections are secure.
If any connectors are found to be damaged, repair or replace them as necessary.

4. Test Seatbelt Switch

Locate the seatbelt switch connector.
Use a multimeter to check for continuity when the seatbelt is buckled and unbuckled.
Replace the seatbelt switch if it does not function correctly.

5. Reconnect Battery and Clear Codes

Reconnect the negative battery terminal.
Use the OBD-II scanner to clear any stored airbag codes.
Ensure all tools and equipment are removed from the vehicle interior.

6. Final Inspection

Start the vehicle and observe the airbag light.
If the light remains off, perform a test drive to ensure airbag system functionality.
