Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, socket set, torx screwdriver, and safety gloves.
Ensure the vehicle is parked on a level surface and the ignition is turned off. Disconnect the battery by removing the negative terminal to avoid accidental deployment of airbags.

2. Retrieve and Clear Codes

Connect the OBD-II scanner to the vehicle's diagnostic port.
Turn the ignition to the "On" position without starting the engine.
Follow the scanner's prompts to read the diagnostic trouble codes (DTCs).
Write down any codes for reference.
Clear the codes using the OBD-II scanner's "Erase" function.

3. Reconvene Connections

Reconnect the negative battery terminal securely.
Check all airbag connectors to ensure they are properly seated and free from corrosion.
If any connections were loose, reseat them and ensure they are secure.

4. Reset Airbag System (If Necessary)

If the airbag light remains on after clearing the codes, use the OBD-II scanner to perform a reset function specific to the airbag system, if supported by the tool.
Follow the scanner's instructions to complete the reset.

5. Final Check

Reconnect the battery and start the vehicle.
Allow the vehicle to run for a few minutes and check if the airbag light remains off.
If the light comes back on, further diagnosis may be required.
