Solution

1. Preparation

Gather tools: OBD-II scanner, socket set, brake fluid (if necessary).
Ensure the vehicle is parked on a level surface and the engine is off.
Wear safety gloves and goggles.

2. Check Brake Fluid Level

Open the hood and locate the brake fluid reservoir.
Inspect the fluid level; it should be between the "MIN" and "MAX" markings.
If low, top off with the appropriate brake fluid type as specified in the owner’s manual.

3. Resetting the Brake Warning Light

Connect the OBD-II scanner to the vehicle’s diagnostics port.
Turn the ignition to the "ON" position without starting the engine.
Navigate the scanner menu to find the option for "Read Codes" and confirm no active DTCs related to the brake system are present.
If codes are present, address them before resetting.
Select the option to "Clear Codes" or "Reset Warning Light" and confirm the action.

4. Verify Brake System Performance

Start the vehicle and check the brake warning light.
Test the brakes by pressing the pedal to ensure proper function.
Drive the vehicle at a low speed and test for any abnormal behavior.
