Solution

1. Preparation

Tools Required: Socket set, OBD-II scanner, fluid catch pan, rags, and a flashlight.
Ensure the vehicle is parked on a level surface and the engine is cool before starting repairs.

2. Inspect and Clean Engine Components

Sub-steps:
1. Open the hood and visually inspect the engine for any burnt wiring or hoses.
2. Check for oil leaks around the engine and oil pan. Clean any areas that show signs of oil leakage.
3. If any wires are burnt, replace the damaged wiring using appropriate gauge wire and connectors.

3. Check and Replace Fluids

Sub-steps:
1. Check the engine oil level and condition. If the oil appears burnt or is low, drain and replace with the correct type and viscosity of engine oil.
2. Inspect and replace the coolant if it shows signs of contamination or is low.
3. If the transmission fluid is burnt, drain and replace it with the manufacturer-recommended fluid.

4. Brake Inspection and Repair

Sub-steps:
1. Inspect brake pads and rotors for excessive wear. Replace pads if they are worn down or damaged.
2. Check for any issues with the brake calipers that could cause them to stick.
3. If dragging brakes are found, service or replace the affected brake components.

5. Reassemble and Test

Sub-steps:
1. Reassemble any components removed during inspection.
2. Start the engine and allow it to idle while monitoring for any new smells or sounds.
3. Take the vehicle for a short test drive to verify that the burning smell is resolved.
