Solution

1. Preparation

Tools Required:
- OBD-II scanner
- Socket set
- Wrench set
- Multimeter
Ensure the vehicle is parked on a level surface and the engine is cool. Disconnect the battery to avoid electrical hazards.

2. Inspect and Clean Engine Bay

Remove any debris or foreign materials in the engine bay.
Check for oil or coolant leaks; clean any spills to prevent burning smells.
If any burnt wiring is found, proceed to replace the affected wiring.

3. Fluid Change (if necessary)

Oil Change:
- Drain the old oil and replace with new oil according to manufacturer's specifications.
- Replace oil filter as well.
Coolant Replacement:
- Drain the old coolant and refill with the recommended coolant type, ensuring no air bubbles remain in the system.

4. Brake Inspection and Replacement (if required)

Remove the wheel to access the brake components.
Inspect brake pads and rotors for excessive wear (less than 3mm thickness indicates replacement).
Replace brake pads and machine or replace rotors as necessary, ensuring to follow torque specifications during reassembly.

5. Electrical Repair (if necessary)

Identify any damaged wiring or connectors and replace them with parts that meet OEM specifications.
Use a multimeter to confirm that all electrical connections are functioning correctly.
