Solution

1. Preparation

Gather tools such as an OBD-II scanner.
Ensure the vehicle is in a safe, level area and the engine is off.

Press the start/stop button without pressing the brake pedal to turn on the electrical systems.
Use the OBD-II scanner to connect to the vehicle’s diagnostic port (usually located under the dashboard).
Navigate to the brake system module on the scanner menu.
Select the option to clear or reset the brake warning light.
Disconnect the scanner once the reset is complete.

4. Test the System

Start the vehicle and check if the brake warning light is still illuminated.
