Solution

1. Preparation

Gather tools: flashlight, OBD-II scanner, socket set, multimeter, and safety gloves.
Park the vehicle on a flat surface, turn off the engine, and allow it to cool down.

2. Inspect and Clean Components

Check Engine Oil and Coolant:
- Remove the engine oil dipstick and check the oil level. Add oil if low, and inspect for burnt or contaminated oil.
- Check the coolant reservoir for proper levels. Top off if necessary with the recommended coolant type.
Inspect Brake System:
- Remove the wheel to access the brake components.
- Inspect brake pads and rotors for excessive wear or overheating. Replace worn brake pads or rotors if needed.
- Clean the caliper and brake components with brake cleaner.

3. Address Electrical Issues

Inspect Wiring:
- Examine visible wiring and connectors for any signs of damage or melting. Repair or replace any damaged wiring.
Check Battery Connections:
- Ensure battery terminals are clean and tight. Corrosion should be cleaned using a mixture of baking soda and water.

4. Fluid Leaks and Overheating

Identify Leaks:
- Clean the area where fluid leaks are observed and monitor for new leaks after the vehicle has been driven.
Replace Faulty Components:
- If any fluid leaks are identified (e.g., oil or coolant), replace the damaged seals, gaskets, or hoses.
