Solution

1. Preparation

Tools Required: Socket set, wrenches, OBD-II scanner, multimeter, flashlight.
Ensure the vehicle is parked on a level surface and the engine is off and cool.
Disconnect the battery to prevent electrical shorts.

2. Inspect Engine Components

Sub-steps:
1. Open the hood and visually inspect for any signs of burnt oil or fluid around the engine.
2. Check the condition of belts and hoses; replace any that show cracks or significant wear.
3. Look for frayed wiring or burnt connectors, particularly around the alternator and starter.

3. Check Fluid Levels

Sub-steps:
1. Inspect the engine oil level using the dipstick and add oil if necessary.
2. Check the coolant level in the reservoir; top off if low, and inspect for leaks.

4. Electrical System Inspection

Sub-steps:
1. Use a multimeter to test the battery voltage; it should read between 12.4 to 12.7 volts.
2. Inspect the alternator for proper functioning by checking voltage output while the engine is running (should be around 13.8 to 14.4 volts).

5. Resolve Identified Issues

Replace any damaged belts, hoses, or electrical components identified during inspection.
If oil or coolant leaks are found, repair the source of the leak and replace any affected fluids.
