Solution

1. Preparation

Tools Required: Gather an OBD-II scanner, socket set, visual inspection tools (flashlight), and a multimeter.
Safety Warnings: Disconnect the battery before working on electrical systems and allow the engine to cool before inspection.

2. Inspect and Identify the Source

Lift the Vehicle: Use a jack and jack stands to safely lift the vehicle for undercarriage inspection.
Look for Fluid Leaks: Examine the ground beneath the vehicle for any fluid leaks (oil, transmission fluid, etc.) and trace the source.
Check Brake System: Remove the wheel to inspect the brake components for excessive wear or overheating.
- Sub-steps:
  - Measure brake pad thickness; replace if less than manufacturer specifications.
  - Check brake rotor condition for warping or discoloration.
Examine Engine Compartment:
- Visually inspect wiring harnesses for damage or melted insulation.
- Check for any signs of oil leaks around engine seals or gaskets.
Scan for Codes: Connect the OBD-II scanner and record any error codes. Address issues indicated by the codes.

3. Repair or Replace Affected Components

Replace Worn Brake Components: If brake pads or rotors are found to be worn, replace them with OEM or equivalent parts.
Repair Electrical Wiring: If any damaged wiring is found, repair or replace the affected sections of the harness.
Fix Fluid Leaks: Replace any gaskets, seals, or hoses that are leaking and causing the burning smell.
Replace Drive Belts: If belts are worn or frayed, remove and replace them with new ones, ensuring proper tension.
