Diagnostics of the car

The days when the master could determine the damage, as they say, "by ear", are gone in past. Not tricky electrical equipment such as a tester and a control bulb are very weak assistants in the repair of modern vehicles.

What to do, if the car is gradually transformed from a "mechanical miracle" in an electronic device. That is why it’s better to talk to electronics on its "own" language. That's why we need computer diagnostics. It remains only to find out when and why ...

Something computer diagnostics was really a great gimmick. But since technological progress has started to displace from our garages and streets soviet car mastodons, diagnostic equipment has become commonplace for a modern service center. And it is quite natural.

As evidenced by the brutal truth of life, nothing is eternal, and the more that created the automotive industry. In addition, it is no secret that much damage begins with small problems that sometimes it is very difficult to determine without special equipment. Such faults can, for example, include malfunctions the coolant temperature sensor, air flow and temperature, and many other similar devices. The principle behind their normal work should follow the system on-board computer, alerting the driver of all the identified failures. But often it happens that a small change in terms of vibrations are perceived as acceptable and there were problems go unnoticed.

Computer diagnostics does not suffer in such compromises and therefore is able to test not only the work of all electronic systems and control units, but also, through the analysis of all the data, determine the actual state of the mechanical components and parts.

Diagnosis is a process that is quite complex and consistently covers all the vital systems of the vehicle, such as engine control, powertrain, safety systems (including anti-lock brakes, traction control, a system of exchange rate stability, the system of distribution of braking forces, emergency brake, electronic differential lock) , climate control, instrument panel, cruise control, air suspension, immobilizer, parking, navigation, and so on).

In addition, the diagnostics of each node also is held in a deep and multi-layered way. For example, while engine testing conducted: systems testing, engine control, diagnosis of the fuel system control filling of cylinders, number of revolutions of the analysis, and so on. While rigorous verification the errors are eliminated at all.

After the test data have been collected, the computer analyzes them by comparing them to the existing database, and generates an optimal plan to eliminate the identified faults. In addition, you can familiarize yourself with the report on identified errors and failures, as well as proposals for the repair or replacement of defective components and assemblies.

Computer diagnostics can not only quickly and accurately identify possible failure, but also to make an overall assessment of the technical condition of the car.

Experts advise to take computer diagnostics regularly and at least the terms specified in the operating manual of your vehicle. And if you suspect poor performance of any system, it is necessary to carry it out, and graphics. Timely detection of malfunctions allows you not to go to serious malfunctions, and thus save money on major repairs and extend the life of your machine.

Diagnostics of the car is particularly important when buying a car with mileage. In this case, the technical condition, which can be accurately determined in the process of diagnosis, not only determines the real value of the vehicle-specific, but generally the feasibility of its acquisition.

As a rule, all the cars being prepared for sale, are subject to special pre-training, which aims to hide from potential buyers, "weak" places. And if the external evaluation of the state lies only on your shoulders, the technical control diagnostic equipment indispensable tool.

It is possible that even if the car is in good condition, his "body" does not carry the symptoms of a disease, which is able to easily grow into big damage. Or worse, the wear of one of the units is at a critical level and needs to be replaced in the coming time.

There is one important caveat, which often forget the owners of modern cars. During operation in the vehicle anyway, errors occur and high failure information, which enters the electronic control unit as defined error codes and settle there. Even after this failure is corrected, the code remains in memory and can easily lead to malfunction of the different systems.

During the diagnosis all the accumulated error in the computer memory shall be canceled and the normal operation of the unit. Besides, if you want to, when to have a special card can diagnose your car, which will be recorded all the results of each of your check. This allows not only to monitor the dynamics of changes in the technical condition of the car with the passage of time, but also facilitate the process of identifying problems and speed up the repair process.
