Hello. Welcome to Just Answer. Please allow me to assist you. I do not think you have any fuse issues. If the check engine light is on, that indicates that you have a problem with something in either the engine electrical system or the emission control system. Traditionally, when the check engine light comes on, it also causes the VSC and the SLip indicator to illuminate also. SInce the other lights are flashing, you may have two different issues at the same time. To speculate on the actual cause of the issue would be guessing, The proper way to determine the issue would be to take the vehicle to a shop where a technician can scan the car with a computer test-box. This will extract important information as to why the lights are illuminated. A lot of auto parts stors (Pe Boys/NAPA/Autozone, etc) perform this service for free (so they can sell you th eparts you need). That would be the recommendation I have for you on thsi request. Once you have the causes for the lights coming on known, it will be very easy to determine the next steps and possible replacement of a failed part. One thing that can and will cause these lights to come on (and there is nothing wrong with the vehicle) is a fuel filler cap that is not as tight as you can make it. There is a sensor that measures the pressure of the gasoline vapor in the tank. If the cap is loose, even just a tiny bit, there will be no pressure in the tank and the sensor that measures this will turn on the lights.
