Computer diagnostics of the engine - the solution of many problems

Diagnosis is an integral part of anyrepair, whether it be an engine or a suspension. The mechanic first has to figure out what exactly needs to be disassembled and replaced. You can make a diagnosis, for example, on the eye: examined the detail, thought, made the right conclusions and forward, for the work. Or choose the "method of poking" - tried to twist here, if it did not work, then you can try to adjust something else and so on. But the most accurate in the testimony is the computer diagnostics of the engine.

In order to produce it, you needspecial equipment for the diagnosis of the engine, which will detect almost all the malfunctions of the car. 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, which connects to a special connector, using a cable for this. After that, information about the error codes that occur in the car is read. It is also possible to control the actuators. Computer diagnostics of the engine can be made both on stationary and on portable equipment.

When the car is sent for reasonsany malfunctions in the system, it is worth remembering that even the most simple problem requires at least half an hour of scanning by the scanner. Often, there are situations when an inexperienced mechanic, after making one check, states that the computer diagnostics of the engine has shown a malfunction of some sensor. As a result, it turns out that they just forgot to connect it, and the problem remains unresolved.

Often car enthusiasts are mistaken, thinking thatsimple erasing of the error code, when computer diagnostics of the engine is performed, will correct the problem. However, this is absolutely not the case. When executing this action, the error will still occur at each startup, as the electronic control unit (ECU) checks each time the engine is turned on and can distribute the codes either randomly or static. In order for the problem not to arise, it is enough after the motor has been stopped to fix the problem, thereby the error will no longer occur and the code will be erased from the computer's memory.

To computer diagnostics of the enginecar was considered accurate, use a motor tester. It is a device that processes various information using one or more processors. The motor tester shows various light signals that need to be interpreted in the diagnosis of the car. This work is more often done by skilled and knowledgeable experts. With its use, the time for diagnosis is increased by 2-3 times.

It follows that the diagnosis of the enginerather difficult process, it is not necessary to require experts to work quickly. Of course, they can do it, but in a short period of time and the information will be "fake". Therefore, it is worthwhile to think about what is more advantageous: wait a couple of hours and find out the exact problem or pay a lot of money and do nothing.
