Solution

1. Preparation

Gather tools and equipment: OBD-II scanner, torque wrench, and any necessary replacement parts.
Ensure the vehicle is parked on a level surface with the ignition off.
Disconnect the negative battery terminal and wait for at least 10 minutes before proceeding to ensure airbag system power is discharged.

2. Use OBD-II Scanner

Connect the OBD-II scanner to the vehicle's diagnostic port, usually located under the dashboard near the steering column.
Turn the ignition to the "ON" position without starting the engine.
Navigate to the airbag module section on the scanner.
Read and note any fault codes present.

3. Clear Fault Codes

Follow the OBD-II scanner instructions to clear the fault codes.
After clearing, turn the ignition off for a few seconds, then turn it back to the "ON" position.
Observe if the airbag light remains off. If it does not, further diagnosis may be required.
