Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, multimeter, trim removal tools.
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 Address Error Codes

Use the OBD-II scanner to read any stored airbag fault codes.
Document the codes and refer to the service manual for specific troubleshooting related to the retrieved codes.
Clear the codes to see if the light returns after addressing the issues.

3. Inspect and Repair Wiring

Remove the necessary trim panels to access the airbag wiring harness.
Check for frayed wires, poor connections, or damaged connectors.
- If damaged, repair or replace the affected wiring.
Ensure all connectors are securely fastened and free of corrosion.

4. Seatbelt and Airbag Component Inspection

Inspect the seatbelt buckle switches for proper functionality.
Replace any faulty seatbelt buckle switches if necessary.
Check the condition of the airbag modules and their connectors.
- If any modules are found to be non-functional, replace them according to specifications.

5. Reassembly and Testing

Reattach any trim panels removed during the inspection.
Reconnect the negative battery terminal.
Perform a system check by turning the ignition to the "On" position and observing if the airbag light goes off after a few seconds.
If the light remains illuminated, further diagnosis may be required.
