Solution

1. Preparation

Gather tools: socket set, OBD-II scanner, multimeter, coolant tester, and safety goggles.
Ensure the vehicle is parked on a flat surface and the engine is cool before starting work.

2. Inspect Engine Components

Sub-step 1: Open the hood and visually inspect the wiring harness for damaged insulation or burnt wires.
Sub-step 2: Check for leaking fluids; inspect hoses and connections for wear and tear.
Sub-step 3: Look for signs of oil or coolant leaks that may have reached hot engine components.

3. Change Fluids if Necessary

Sub-step 1: If the engine oil is burnt, drain the old oil using a socket set and replace it with the manufacturer-recommended oil (5W-20 for Honda Civic).
Sub-step 2: If coolant is contaminated, drain the old coolant and refill with a 50/50 mix of Honda Long Life Coolant and distilled water.
Sub-step 3: Dispose of old fluids properly at a recycling center.

4. Repair or Replace Faulty Components

Sub-step 1: If damaged wiring is found, repair the wiring using electrical tape or replace it as necessary.
Sub-step 2: Replace any faulty hoses or components that are leaking.
Sub-step 3: If brake components are found to be burnt, replace the brake pads and inspect rotors.

5. Reassemble and Test

Sub-step 1: Reinstall any components removed for inspection and ensure all connections are secure.
Sub-step 2: Start the engine and monitor for any smells or leaks.
Sub-step 3: Take the vehicle for a short test drive to ensure the issue has been resolved.
