Solution

1. Preparation

Gather tools and materials: socket set, wrench set, OBD-II scanner, multimeter, and a flashlight.
Ensure the vehicle is parked on a flat surface and the engine is cool before starting.

2. Inspect and Replace Fluids

Check Engine Oil:
- Pull the dipstick and check the oil level; add oil if low.
- If oil appears burnt (dark color and burnt smell), change the oil and filter.
Check Coolant Level:
- Open the radiator cap and check coolant level; refill with manufacturer-recommended coolant if low.
- Check for leaks in hoses and connections; replace any damaged hoses.

3. Inspect and Replace Components

Brakes:
- Remove the wheel to access brake components.
- Inspect brake pads for wear; replace if less than 3mm thick and check caliper movement.
Wiring and Electrical Components:
- Examine wiring for signs of melting or fraying.
- Replace any damaged wiring or connectors as needed.

4. Clear Codes and Test Drive

Use the OBD-II scanner to clear any error codes.
Test drive the vehicle to ensure that the burning smell does not return and monitor for any warning lights.
