Solution

1. Preparation

Tools Required: Socket set, OBD-II scanner, multimeter, brake pad gauge.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery for safety before starting repairs.

2. Identify Source of Burning Smell

Inspect Components:
- Check for leaking fluids (oil, coolant, brake fluid) that may be burning on hot engine parts.
- Look for damaged electrical components or wires.

3. Address Brake Issues (if applicable)

Remove Wheel:
- Use a jack to lift the vehicle and secure it with jack stands.
- Remove the wheel using a socket set.
Inspect Brake Pads and Rotors:
- Check brake pads for wear; replace if they are thin or damaged.
- Inspect rotors for scoring or overheating; machine or replace as necessary.

4. Replace Damaged Components

Fluid Leaks:
- If a fluid leak is identified, replace the affected hose or seal (e.g., oil filter, coolant hose).
Electrical Repairs:
- If damaged wires are found, cut out the damaged section and splice in new wire, ensuring proper insulation.

5. Reassemble and Reconnect

Reinstall any components removed during inspection and repair.
Reconnect the battery and ensure no tools are left in the engine bay.
