Solution

1. Preparation

Tools Required: Safety goggles, gloves, flashlight, and a jack with jack stands.
Ensure the vehicle is parked on a flat surface and the engine is cool before beginning any work.

2. Inspect and Clean Engine Components

Sub-steps:
- Open the hood and visually inspect for any burnt wires, hoses, or components.
- Check for oil leaks around the valve cover and oil pan. If leaks are found, clean the area and replace the faulty gaskets.
- Use a degreaser to clean any oil or debris from the engine to prevent further burning smells.

3. Brake System Inspection

Sub-steps:
- Raise the vehicle using a jack and secure it with jack stands.
- Remove the wheel to gain access to the brake components.
- Inspect brake pads and rotors for excessive wear or damage. Replace pads or rotors if they are worn down or burnt.
- Ensure that brake fluid is at the appropriate level and is clean; replace if it appears contaminated.

4. Transmission Fluid Check

Sub-steps:
- With the engine running, check the transmission fluid level using the dipstick.
- If the fluid is low, top it off with the manufacturer's recommended fluid type. If burnt, drain and replace the fluid.
- Inspect for any leaks around the transmission cooler lines.
