Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, multimeter, coolant pressure tester.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to avoid electrical shorts.

2. Inspect and Replace Fluids

Oil Inspection:
1. Remove the oil dipstick and check oil level and condition.
2. If oil is low or burnt, drain the old oil using an oil catch pan.
3. Replace with the manufacturer-recommended engine oil.
Coolant Inspection:
1. Check the coolant reservoir for appropriate levels.
2. If low, inspect for leaks in hoses and the radiator.
3. Refill with the manufacturer-specified coolant and bleed the system if necessary.

3. Brake Component Inspection

Remove the wheel and inspect brake pads and rotors for excessive wear or overheating.
Replace any worn brake components as needed.
Ensure caliper slides and pins are lubricated to prevent sticking.

4. Electrical Inspection

Visually inspect engine wiring harnesses for burnt or damaged insulation.
Use a multimeter to check for continuity and shorts in electrical connections.
Repair or replace any damaged wiring or connectors.

5. Reassemble and Test

Reconnect the battery and ensure all tools are removed from the engine bay.
Start the engine and monitor for any unusual smells or noises.
Test drive the vehicle to confirm the issue is resolved.
