Solution

1. Preparation

Gather tools and parts required for inspection and repairs.
Ensure the vehicle is parked on a flat, stable surface and the engine is cool.
Disconnect the battery to avoid any electrical hazards.

2. Inspect and Replace Fluids

Engine Oil:
- Remove the oil dipstick and check the oil level and condition.
- If low or dirty, drain the old oil using an oil pan, replace the oil filter, and refill with manufacturer-recommended oil.
Transmission Fluid:
- Locate the transmission dipstick and check the fluid level.
- If necessary, drain and replace the fluid as per the service manual specifications.

3. Brake System Inspection

Remove the wheel to access the brake assembly.
Inspect brake pads and rotors for wear. Replace if they show signs of excessive wear or glazing.
Check for brake fluid leaks around calipers and hoses.

4. Exhaust System Check

Inspect the exhaust manifold and pipes for any signs of leaks or damage.
Repair or replace any damaged components, ensuring a proper seal to eliminate the burning smell.

5. Electrical System Assessment

Examine wiring harnesses and connectors for any signs of wear or overheating.
Replace any damaged electrical components and ensure all connections are secure.
