Solution

1. Preparation

Gather tools and materials: OBD-II scanner, socket set, multimeter, brake cleaner, shop towels, and safety gloves.
Ensure the vehicle is parked on a level surface and the engine is cool.

2. Address Fluid Leaks

Sub-steps:
1. If any fluid leaks are found, determine the source (e.g., oil pan, coolant hoses).
2. Replace any damaged hoses or seals as necessary.
3. If oil is leaking onto hot engine components, clean the area with brake cleaner and shop towels to prevent further burning smells.

3. Inspect and Replace Brake Components

Sub-steps:
1. Remove the wheel to access the brakes.
2. Inspect the brake pads and rotors for wear. Replace the brake pads if they are worn down to the indicators.
3. Ensure the calipers are functioning properly. If they are sticking, they may need to be serviced or replaced.
4. Reassemble the wheel and lower the vehicle.

4. Electrical Inspection

Sub-steps:
