Solution

1. Preparation

Tools Required: OBD-II scanner, a flathead screwdriver, and a 10mm socket wrench.
Ensure the vehicle is parked on a flat surface, and the engine is turned off. Disconnect the negative battery terminal and wait for at least 15 minutes to allow the system to discharge.

2. Scan for Codes

Connect the OBD-II scanner to the vehicle’s diagnostic port, typically located under the dashboard.
Turn the ignition key to the "ON" position without starting the engine.
Follow the scanner prompts to retrieve any airbag-related trouble codes. Write down any codes for reference.

3. Clear Codes

With the OBD-II scanner still connected, navigate to the option to clear or erase codes.
Confirm the action and wait for the scanner to complete the process.
Once cleared, disconnect the scanner.

4. Reconnect Battery

Reconnect the negative battery terminal securely.
Ensure all connections are tight and proper.

5. Test the System

Start the vehicle and observe the dashboard for the airbag light.
The airbag light should illuminate briefly and then turn off, indicating the system is functioning correctly.
