Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, wire connectors, and electrical tape.
Ensure the vehicle is parked on a flat surface with the ignition off and the key removed.

2. Retrieve Trouble Codes

Connect the OBD-II scanner to the vehicle's diagnostic port.
Turn the ignition to the "ON" position without starting the engine.
Read and record any airbag-related trouble codes.

3. Inspect Wiring and Connectors

Remove the front seats if necessary to access the wiring underneath.
Check the connectors at the seat belt and airbag for corrosion or damage.
Use a multimeter to test continuity in the wiring harness.

4. Replace Faulty Components

If any components such as connectors, sensors, or the airbag control module are found faulty, replace them with OEM parts.
Ensure all connectors are securely attached and free of corrosion.

5. Clear Codes and Test

After repairs, use the OBD-II scanner to clear any stored airbag trouble codes.
Start the vehicle and verify that the airbag light is no longer illuminated.
