Solution

1. Preparation

Tools Required: OBD-II scanner, infrared thermometer, socket set, safety goggles, gloves.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to prevent electrical shorts during inspection.

2. Inspect and Clean the Engine Compartment

Sub-steps:
1. Visually inspect the engine bay for any oil leaks or burnt components.
2. Clean any spilled fluids using an appropriate degreaser.
3. If any burnt wiring is discovered, mark the area for replacement.

3. Check and Replace Engine Oil (if necessary)

Sub-steps:
1. Remove the oil dipstick and check the oil level; add oil if low.
2. If oil appears burnt (dark and thick), drain and replace with manufacturer-recommended oil.
3. Change the oil filter during the oil change to ensure clean oil circulation.

4. Inspect and Service the Brakes

Sub-steps:
1. Remove the wheel to access the brake components.
2. Inspect brake pads, calipers, and rotors for signs of overheating or wear.
3. Replace any worn brake pads or damaged components as necessary.

5. Repair or Replace Damaged Wiring
