Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface, and the ignition is off.
Disconnect the vehicle's battery and wait for at least 15 minutes to allow any residual power to drain.

2. Accessing the Airbag Control Module

Remove the driver's side lower dash cover using a screwdriver or socket set.
Locate the airbag control module, usually positioned near the steering column or under the seat.

3. Resetting the Airbag Light

Reconnect the battery.
Use the OBD-II scanner to connect to the vehicle's diagnostic port.
Access the airbag control module section on the scanner.
Follow the prompts to clear any stored error codes.

4. Final Checks

Turn the ignition on (do not start the engine) and observe the airbag light.
If the airbag light remains off, the reset was successful. If it stays illuminated, further diagnostics may be needed.
