Solution

1. Preparation

Tools Required: Socket set, pliers, OBD-II scanner, multimeter, fluid catch pan.
Safety Warnings: Disconnect the battery before working on electrical systems; allow the engine to cool before opening the hood.

2. Addressing Fluid Leaks

Sub-steps:
1. If any fluid leaks are detected, identify the source (e.g., oil pan, radiator, hoses).
2. Tighten any loose connections or replace damaged hoses.
3. If necessary, replace the leaking component (e.g., radiator, oil filter, or hose).

3. Inspecting and Replacing Brake Components

Sub-steps:
1. Remove the wheel where the burning smell is strongest.
2. Inspect brake pads and rotors for signs of wear or overheating.
3. Replace pads if they are worn down or if the rotors are warped or damaged.

4. Electrical System Inspection

Sub-steps:
1. Visually inspect all wiring and connectors in the engine bay for damage or wear.
2. Use a multimeter to check for short circuits or grounding issues.
3. Replace any damaged wires or connectors.

5. Coolant System Check

Sub-steps:
1. Inspect the radiator and coolant hoses for leaks or damage.
2. Ensure the radiator cap is functioning properly and seals tightly.
3. If low on coolant, refill with the appropriate type and mixture as specified in the owner's manual.
