Solution

1. Preparation

Gather necessary tools such as an OBD-II scanner, socket set, and a flathead screwdriver.
Ensure the vehicle is parked on a flat surface and the ignition is turned off.
Disconnect the vehicle’s battery and wait for at least 10 minutes to ensure all capacitors discharge, which helps prevent accidental airbag deployment.

2. Access the Airbag Module

Remove the necessary trim panels to access the airbag control module, usually located under the dashboard or near the center console.
Use a socket set to remove any screws or bolts securing the trim.

3. Clear Diagnostic Codes

Reconnect the battery and turn the ignition to the "On" position without starting the engine.
Connect the OBD-II scanner to the vehicle's diagnostic port and follow the scanner’s instructions to clear any DTCs related to the airbag system.
After clearing the codes, turn off the ignition.

4. Verify System Functionality

Turn the ignition back to the "On" position and check if the airbag warning light is still illuminated.
If the light remains off, proceed to reassemble any trim pieces removed earlier.

5. Reassemble

Reinstall any trim panels that were removed to access the airbag module, ensuring all screws and clips are secure.
