Diagnosis is an integral part of any repair, whether it's an engine or suspension. The mechanic must first figure out what exactly needs to be disassembled and replaced. You can make a diagnosis, for example, by eye: they examined the part, thought, made the right conclusions and go ahead, to work. Or choose the “poke method” - I tried to twist it here, if it didn’t work out, then you can try to adjust something else and so on. But the most accurate readings are computer diagnostics of the engine.
In order to produce it, you will need special equipment for engine diagnostics, which will reveal almost all car malfunctions. For this work, motor testers or scanners are provided. With the help of the first device, various quantities are checked and measured. The scanner is an external computer that is connected to a special connector using a cable. After that, information about the error codes that occur in the car is read. It is also possible to control the actuators. Computer diagnosticsengine can be produced both on stationary and portable equipment.
When a car is sent to identify the causes of any malfunctions in the system, it is worth remembering that even the simplest problem requires at least half an hour of scanning by a scanner. Often there are situations when an inexperienced mechanic, having made one check, declares that the computer diagnostics of the engine showed a malfunction of some kind of sensor. And as a result, it turns out that they simply forgot to connect it, and the problem remains not found.
Often, motorists are mistaken in thinking that simply erasing the error code when performing computer engine diagnostics will fix the problem. However, this is absolutely not the case. When doing this, the error will still occur at every start, since the electronic control unit (ECU) checks every time the engine is turned on, and can distribute codes as random or static. In order for the problem not to arise, it is enough to simply fix the problem after stopping the engine, thereby the error will no longer occur, and the code will be erased from the ECU memory.
In order for computer diagnostics of a car engine to be considered accurate, a motor tester is used. This is a device that processes various information using one or more processors. The motor tester shows various light signals that need to be interpreted into a vehicle diagnosis. This work is more often done by skilled and knowledgeable people.specialists. When using it, the time for diagnostics increases by 2-3 times.
From this it follows that engine diagnostics is a rather difficult process, you should not demand quick work from specialists. Of course, they can do this, but in a short period of time, the information will turn out to be “fake”. Therefore, it is worth considering what is more profitable: to wait a couple of hours and find out the exact problem, or to pay big money and do nothing.

Engine diagnostics is a set of measures to identify deviations in the operation of components that can disable an expensive unit. All necessary tests are included in the full cost of the service. However, to reduce the price, the masters reduce the established list
Auto: computer diagnostics and equipment
All modern electronic control systems that are designed to control the car are equipped with self-diagnosis, designed to inform the driver about malfunctions. Many motorists have noticed the Check Engine indicator illuminating when the key is turned. It goes out a second after starting the engine. If the system detects a malfunction in the vehicle, the indicator will not turn off. In this case, computer diagnostics is required for your car

Almost every car owner had to deal with such a problem as increased noise when driving a car. Often this problem can cause not only discomfort for the driver and passengers, but also lead to an accident. Therefore, if you notice extraneous noise while driving a car, you need to determine its source as soon as possible
