Solution

1. Preparation

Tools Required: OBD-II scanner, flashlight, basic hand tools (sockets, wrenches), multimeter, brake cleaner.
Safety Warnings: Ensure the engine is cool before inspecting. Disconnect the battery if working on electrical components.

2. Address Fluid Leaks

Identify the Leak: Clean the area around potential leaks and run the engine to observe where fluids are coming from.
Repair or Replace: If oil or coolant is leaking, replace gaskets or hoses as necessary. Use proper seals and torque specifications.

3. Brake System Inspection and Maintenance

Remove Wheel: Use a jack to lift the vehicle and remove the wheel to access brake components.
Inspect Brake Pads and Rotors: Check for excessive wear. Replace pads if they are below the manufacturer's recommended thickness or if they show signs of burning.
Reassemble: Reinstall the wheel and lower the vehicle once repairs are completed.

4. Electrical System Repair

Inspect Wiring: Look for damaged or melted wires. Repair or replace any damaged wiring with heat-resistant materials.
Test Components: Use a multimeter to check the voltage at electrical components. Replace faulty components as needed.

5. Cooling System Maintenance

Check Coolant Levels: Ensure the coolant is at the proper level. Refill with the manufacturer-recommended coolant if necessary.
Inspect Radiator and Hoses: Replace any damaged hoses and ensure the radiator is free from obstructions.
