Solution

1. Preparation

Gather tools and parts needed for inspection and repair.
Tools Required: OBD-II scanner, multimeter, socket set, jack and jack stands, brake cleaner, safety glasses, gloves.
Safety Warnings: Ensure the vehicle is on a flat surface and in park with the engine off before beginning any inspection.

2. Identify and Repair Fluid Leaks

Inspect all areas of the engine for oil, coolant, or other fluid leaks.
If a leak is found:
1. Clean the area with brake cleaner to remove spilled fluids.
2. Replace worn seals or gaskets as necessary.
3. Refill fluids to the appropriate levels.

3. Brake System Inspection

Remove the wheel to access the brake components.
Inspect brake pads and rotors:
1. Check pads for thickness; replace if below spec.
2. Inspect rotors for warping or scoring; replace if damaged.
3. Clean the brake components using brake cleaner.
Reassemble the braking system securely.

4. Electrical Inspection

Check all visible wiring in the engine bay:
1. Look for any signs of wear, fraying, or burn marks.
2. Repair or replace damaged wiring as necessary.
Test electrical components with a multimeter to ensure proper function.

5. Final Checks

After repairs, ensure all components are secure and fluids are at proper levels.
Test drive the vehicle to ensure the burning smell has dissipated and no new smells arise.
