Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface with the engine turned off and the keys removed from the ignition.

2. Disconnect the Battery

Use a socket wrench to loosen the negative battery terminal clamp.
Remove the clamp and ensure it does not come into contact with the battery terminal.
Wait at least 10 minutes before proceeding to allow any residual current to dissipate.

3. Access the Airbag System

Depending on the specific issue, access the airbag control module located under the dashboard or the driver's seat.
Use a Torx screwdriver to remove screws securing any panels that may obstruct access.

4. Check Connections

Visually inspect and reconnect any loose or damaged wiring and connectors related to the airbag system.
Ensure that seat belt tensioners and airbag connectors are secure.

5. Reconnect the Battery

Reattach the negative battery terminal clamp and tighten it securely.
Ensure no tools or loose items are left in the engine compartment.

6. Reset Airbag Light

Reconnect the diagnostic tool to the OBD-II port.
Follow the tool’s prompts to clear error codes and reset the airbag light.
Confirm that the airbag light remains off after clearing the codes.
