Solution

1. Preparation

Gather tools and materials: OBD-II scanner, multimeter, socket set, and replacement parts as needed.
Ensure the vehicle is parked on a level surface with the ignition off. Disconnect the negative battery terminal to prevent accidental deployment of airbags.

2. Retrieve Diagnostic 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 displayed on the scanner.

3. Inspect Fuses and Wiring

Locate the fuse box and check the airbag system fuses using a multimeter for continuity.
If a fuse is blown, replace it with the same amperage rating.
Inspect the wiring harnesses for moisture, corrosion, or loose connections.

4. Check Seat Belt Pretensioners

Remove the seat cushions if necessary to access the seat belt pretensioners.
Inspect the pretensioner and its connector for damage.
Replace any faulty pretensioners with new OEM parts.

5. Reset Airbag Light

After repairs, reconnect the negative battery terminal.
Use the OBD-II scanner to clear the trouble codes and reset the airbag light.
Ensure that the scanner indicates that all codes have been successfully cleared.
