Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to prevent accidental airbag deployment.
Ensure the vehicle is in a safe and level working environment.

2. Scan and Clear Codes

Use an OBD-II scanner to read airbag-related fault codes.
Note any codes that appear and clear them from the system to check if they return.

3. Inspect Components

Airbag Control Module:
- Locate the airbag control module (typically under the driver’s seat or center console).
- Check for loose connections or damaged wiring.
Seatbelt Pretensioners:
- Inspect seatbelt pretensioners for proper operation and check connections.

4. Repair or Replace Faulty Components

If any fault codes point to specific components (e.g., a faulty airbag module or seatbelt pretensioner), proceed to replace those components.
Ensure all connections are secure and free of corrosion.

5. Reconnect Battery and Test

Reconnect the negative battery terminal.
Start the vehicle and observe if the airbag light remains off after a short drive.
