Solution

1. Preparation

Gather tools: OBD-II scanner, socket set, multimeter, and flashlight.
Ensure the vehicle is parked on a level surface and the engine is cool.

2. Engine Inspection

Sub-step 1: Open the hood and visually inspect the engine for signs of oil leaks or burnt components.
Sub-step 2: Check all belts for signs of wear, fraying, or burning.
Sub-step 3: Look for any signs of electrical shorts, such as melted wires or burnt connectors.

3. Brake System Inspection

Sub-step 1: Inspect brake pads and rotors for excessive wear or overheating.
Sub-step 2: Check for any abnormal burning smell coming from the wheel wells, which may indicate stuck calipers or dragging brakes.
Sub-step 3: Spin the wheels to ensure they turn freely without resistance.

4. Electrical System Check

Sub-step 1: Use a multimeter to check the voltage at the battery and ensure it is within the normal range (12.4 to 12.7 volts when the engine is off).
Sub-step 2: Check the fuses and relays for any signs of damage or burning.

5. Fluid Level Check

Sub-step 1: Inspect the coolant level in the reservoir; add coolant if low.
Sub-step 2: Check transmission fluid and power steering fluid levels; top off as necessary.
