The second lesson of our course on auto diagnostics is devoted to the principles of building an engine management system. For convenience, we have divided it into two parts. In the first part, you will learn what a control system is for and how it is built. We will consider the main components of such systems: namely, control units and sensors. We will also examine in detail everything that an auto diagnostician needs to know about them. And in the second part, we will continue to talk about the main components of control systems and take a detailed look at actuators and their features. We will also talk about communication lines and the nuances of modern control systems. In the second part, we will get closer to the answer to the question: why do you need to know all this and why does a diagnostician need an auto scanner.
