Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is in a safe and stable position (parked on a level surface).
Disconnect the negative terminal of the battery to prevent accidental airbag deployment.

2. Retrieve and Address DTCs

Use an OBD-II scanner to read the stored error codes from the airbag control module.
Document the codes for reference.
If codes are related to faulty components (e.g., seat belt tensioners, crash sensor), replace the defective parts as needed.

3. Clear Airbag Codes

With the OBD-II scanner still connected, navigate to the airbag control module.
Select the option to clear or reset the diagnostic trouble codes.
Follow the prompts on the scanner to complete the code clearing process.

4. Reconnect Battery

Reconnect the negative terminal of the battery.
Ensure the connection is secure and stable.

5. Verify System Functionality

Turn on the ignition and observe the airbag warning light.
The light should illuminate briefly and then turn off, indicating that the system is functioning properly.
