Solution

1. Preparation

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

2. Disconnect the Battery

Using a socket wrench, disconnect the negative terminal of the battery to prevent accidental deployment of the airbag.
Wait at least 10 minutes before proceeding to allow the system to discharge.

3. Access Airbag System Components

Remove the necessary trim pieces around the steering wheel or dashboard to access the airbag control module and connectors.
Carefully locate the airbag module, usually found beneath the steering column or behind the dashboard.

4. Reset the Airbag Light

Reconnect any disconnected connectors securely.
If applicable, use an OBD-II scanner to clear any stored airbag-related DTCs, which may include selecting the airbag system and executing a “clear codes” command.
If a manual reset is required, consult the service manual for specific reset instructions based on the identified DTCs.

5. Reconnect the Battery

Once the reset is complete, reconnect the negative terminal of the battery.
Ensure it is tightened properly to avoid any intermittent connections.

6. Reassemble Components

Reinstall any removed trim pieces carefully, ensuring that all clips and fasteners are securely in place.

7. Test the System

Start the vehicle and check if the airbag light remains illuminated.
If the light turns off, the reset was successful.
