Solution

1. Preparation

Gather tools and safety equipment.
Tools Required: Gloves, safety glasses, OBD-II scanner, socket set, jack and jack stands.
Safety Warnings: Ensure the vehicle is on a flat surface and the engine is cool before beginning work.

2. Addressing Engine Issues

Inspect for Leaks:
- Clean any areas with a burning smell to identify the source.
- Check for oil leaks around the valve cover and oil pan.
Replace Worn Components:
- If oil leaks are found, replace gaskets or seals as necessary.
- Ensure all fluids are topped up.

3. Brake System Inspection

Remove Wheel:
- Use a jack to raise the vehicle and secure it with jack stands.
- Remove the wheel to access the brake components.
Inspect Brake Pads and Rotors:
- Check for wear on pads; replace if less than 1/8 inch thick.
- Examine rotors for scoring or overheating; replace if necessary.
Reassemble:
- Reinstall the wheel and lower the vehicle.

4. Electrical System Check

Inspect Wiring:
- Look for frayed wires or melted insulation near electrical components.
Replace Damaged Wires:
- Cut and splice new wire sections as needed.
- Use electrical tape or heat shrink to seal connections.
