Solution
1. Preparation
  • Tools Required: Socket set, OBD-II scanner, multimeter, flashlight, brake cleaner, shop towels.
  • Park the vehicle on a flat surface and turn off the engine. Allow it to cool down if it has been running.
  • Disconnect the battery to ensure safety while inspecting electrical components.
2. Inspect and Clean Engine Components
  • Oil Inspection:

    • Remove the oil dipstick to check oil level and condition.
    • If oil appears burnt or is low, change the oil and replace the oil filter.
  • Coolant Check:

    • Open the hood and inspect the coolant reservoir for proper levels and leaks.
    • If the level is low, inspect hoses and the radiator for leaks and replace if necessary.
3. Brake System Assessment
  • Brake Inspection:
    • Remove the wheel to access the brake components.
    • Check the brake pads and rotors for excessive wear or overheating; replace as needed.
    • Ensure calipers are functioning correctly and not sticking.
4. Electrical System Examination
  • Wiring and Components:
    • Inspect visible wiring for signs of melting or damage.
    • Check fuses and replace any that are blown.
    • Test electrical components with a multimeter to ensure proper function.
5. Reassemble and Test
  • Reinstall any components removed for inspection.
  • Reconnect the battery and start the vehicle.
  • Monitor for any unusual smells or sounds during a test drive.
