Solution

1. Preparation

Gather tools and parts needed for inspection and repair.
Ensure the vehicle is parked on a flat surface and the engine is cool.
Disconnect the battery to prevent electrical shorts if working on wiring.

2. Engine Inspection

Inspect for Leaks:
- Check for oil, coolant, or other fluid leaks around the engine.
- Use a flashlight to illuminate dark areas.
Clean Surfaces:
- Wipe down any dirty or oily surfaces to identify active leaks more easily.

3. Brake Inspection

Remove Wheel:
- Use a socket set to remove lug nuts and take off the wheel for access.
Examine Brakes:
- Inspect brake pads for wear; replace if less than 3mm thick.
- Check rotors for scoring or overheating discoloration.
- Replace brake components if necessary.

4. Electrical Inspection

Inspect Wiring:
- Look for frayed, burnt, or melted wires in the engine bay.
- Repair or replace damaged wiring as needed.
Check Fuses:
- Inspect relevant fuses in the fuse box for any signs of damage or blown fuses.
