Solution

1. Preparation

Tools Required: OBD-II scanner, flashlight, basic hand tools (socket set, wrenches), safety gloves, and safety glasses.
Ensure the vehicle is parked on a level surface and the engine is off. Allow the engine to cool if previously running.

2. Check for Fluid Leaks

- Replace any damaged components as necessary.

4. Examine Brake Components

Sub-steps:
- Jack up the vehicle and remove the wheels to access the brake components.
- Inspect the brake pads for wear and ensure they are not excessively worn or sticking.
- If calipers are found to be sticking, replace or rebuild them.

5. Assess the Exhaust System

Sub-steps:
- Inspect the exhaust system from the engine to the tailpipe for any cracks, dents, or loose connections.
- Check for any signs of burnt insulation or components near the exhaust.
- Repair or replace any damaged exhaust parts.

6. Reassemble and Test

Sub-steps:
- Reinstall any components removed during inspection.
- Reconnect the battery if it was disconnected.
- Start the vehicle and monitor for any burning smells or other symptoms.
