Solution

1. Preparation

Tools Required: Socket set, OBD-II scanner, brake cleaner
Ensure the vehicle is parked on a level surface and the engine is off. Allow the engine to cool if it has been running.

2. Inspect and Clean Engine Components

Sub-steps:
1. Open the hood and visually inspect for oil or fluid leaks around the engine and oil pan.
2. Clean any spills with brake cleaner to prevent further burning smells.
3. Check the oil level using the dipstick and top off with the manufacturer-recommended oil if low.

3. Brake Inspection and Replacement

Sub-steps:
1. Remove the wheel to access the brake components.
2. Inspect brake pads for wear; if less than 3mm remaining, replace them.
3. Check rotors for scoring or overheating signs; replace if necessary.
4. Reassemble wheel and torque lug nuts to manufacturer specifications.

4. Transmission Fluid Check

Sub-steps:
1. Locate the transmission dipstick (if equipped) and remove it.
2. Check the fluid level and condition; it should be reddish and not burnt.
3. If low or burnt, drain the fluid and replace it with the recommended type, ensuring to replace the filter if applicable.

5. Exhaust System Inspection

Sub-steps:
1. Inspect the exhaust system for any loose connections or signs of damage.
2. Look for any holes or rusted areas that could cause exhaust gases to leak.
3. Repair or replace damaged sections of the exhaust as necessary.
