Solution

1. Preparation

Gather tools: OBD-II scanner, socket set, multimeter, fluid containers, rags.
Ensure the vehicle is parked on a level surface and engine is cool.
Disconnect the battery to prevent any electrical shorts.

2. Inspect and Clean Components

Engine Components:
- Remove engine covers if necessary.
- Visually inspect the engine for burnt wiring, damaged hoses, or oil leaks.
- Clean any spilled oil with rags.
Cooling System:
- Inspect hoses and radiator for leaks. Replace any damaged hoses or radiator.
- Flush the cooling system if contamination is found.

3. Brake Inspection

Remove the wheel and tire assemblies.
Inspect brake pads and rotors for excessive wear or overheating.
Replace worn brake components as necessary.

4. Transmission Fluid Check

Locate the transmission dipstick.
Remove the dipstick and check fluid level. If low, top off with manufacturer-recommended transmission fluid.
If fluid smells burnt, consider a transmission fluid change.

5. Electrical Inspection

Visually inspect all visible wiring for signs of damage or wear.
Use a multimeter to check for proper voltage in critical components.
Repair or replace any damaged wiring.
