One of the worst things that can happen is when you go out to your car to start it only to find that it won’t crank or that it doesn’t run like it should, then you might want to consider the computer. The computer of the car tells the engine and other parts of the car what it needs to do in order to run correctly. You need to look up the latest software updates online before resetting the computer. You will need a reprogrammer. One end will be connected to a port near the steering wheel while another will be connected to a port on your computer. Your computer will download the new software that will be sent to the car. It will take about 30 minutes to reprogram the car, giving your car a new brain to work with.
