Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, multimeter, flashlight
Ensure the vehicle is parked on a level surface and the engine is cool before starting.
Disconnect the negative battery terminal to ensure safety while working.

2. Inspect and Identify the Source of Smell

Sub-step 1: Open the hood and visually inspect for any signs of smoke or burning components.
Sub-step 2: Use a flashlight to check for oil leaks around the engine and oil pan.
Sub-step 3: Check the brake system by looking at the brake pads and rotors for excessive wear or overheating.
Sub-step 4: Examine electrical wiring for melted insulation or burnt connectors.

3. Addressing Identified Issues

If oil leaks are found:
- Sub-step 1: Identify the leak source (e.g., valve cover gasket, oil filter).
- Sub-step 2: Replace the faulty gasket or filter and top off any lost oil.
If brake components are overheated:
- Sub-step 1: Replace worn brake pads and inspect rotors for warping or damage.
- Sub-step 2: Bleed the brake system if necessary to ensure proper function.
If electrical issues are present:
- Sub-step 1: Replace any damaged wiring or connectors identified.
- Sub-step 2: Check electrical components (e.g., alternator) for proper function.
