Solution

1. Preparation

Ensure the vehicle is parked on a level surface and set the parking brake.
Gather necessary tools and parts.

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" marks.
If low, top off with the recommended brake fluid (DOT 3 or DOT 4, depending on specifications).

3. Inspect for Leaks

Visually inspect the brake lines, calipers, and connections for any signs of fluid leaks.
If any leaks are found, replace the damaged components as necessary.
Clean any spilled brake fluid immediately, as it can damage paint.

4. Scan for Fault Codes

Connect an OBD-II scanner to the vehicle's diagnostic port.
Retrieve any brake-related fault codes and document them.
Clear the fault codes after addressing any issues indicated.

5. Reset the Brake Warning Light

After completing any necessary repairs or topping off fluids, turn the ignition to the "On" position without starting the engine.
Wait for approximately 10 seconds to allow the system to reset.
Start the engine and check if the brake warning light is still illuminated.
