1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the ignition is off.
Disconnect the negative battery terminal to prevent accidental deployment of the airbags.

2. Access Airbag Module

Remove the lower dashboard panel or trim piece to access the airbag control module (usually located under the steering column or in the passenger footwell).
Use a socket set to remove any screws or bolts holding the panel in place.

3. Check Connections

Inspect the connectors leading to the airbag module for any corrosion or loose connections.
Reconnect any loose connectors and ensure that all wiring is secure.

4. Reset Airbag Light

Reconnect the negative battery terminal.
Use the OBD-II scanner to clear any stored airbag fault codes again.
Turn the ignition to the "ON" position without starting the engine and wait for a few seconds. Observe if the airbag light turns off.

5. Reassemble Components

Reinstall the lower dashboard panel or trim piece.
Ensure all screws and bolts are tightened to the manufacturer's specifications.
