Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, multimeter, inspection mirror, coolant pressure tester
Ensure the vehicle is parked on a flat surface and the engine is cool before starting any work.
Disconnect the battery to prevent electrical shorts.

2. Inspect and Clean

Sub-steps:
1. Open the hood and visually inspect the engine for burnt wires or damaged components.
2. Use an inspection mirror to check hard-to-see areas.
3. Clean any oil or coolant spills that could be causing the burning smell.

3. Electrical Inspection

Sub-steps:
1. Reconnect the battery and turn the ignition to the "on" position without starting the engine.
2. Use a multimeter to check the voltages at critical electrical connections for irregularities.
3. Tighten any loose connections and replace damaged wiring or components as needed.

4. Fluid Checks and Replacement

Sub-steps:
1. Check engine oil and coolant levels; top off or replace as necessary.
2. If the oil is burnt or contaminated, perform an oil change using manufacturer-recommended oil.
3. If coolant is low, inspect hoses and the radiator for leaks; repair or replace as necessary.

5. Brake System Inspection

Sub-steps:
1. Inspect brake pads and rotors for wear and overheating signs.
2. Replace any worn brake components and ensure brake fluid is at the proper level.
