Almost all modern cars are equipped with a car computer. This device, PC-like, consists of a small box with drivers, memory and processor. It is the on-board computer that we owe information about errors on the dashboard, through which we know, it's time to contact the service center.
Computer diagnostics - help in troubleshooting
At one hundred specialist connects a special diagnostic tool to the car's computer. It reads error information from auto PC memory, which are visible as codes. In Europe, universal error codes are used for all machines, but deciphering them requires special knowledge, also worth considering, that some brands may have certain differences.
It is not recommended to conduct computer diagnostics on your own, and entrust this work to the master. Let's give an example, at car engine diagnostics code P0100 reports a mass air flow error. In some vehicles, this error can lead to the activation of the emergency engine operation. (speed is limited to 3.000 thousand. rev / min), in others - a complete stop of the TK. However, it is worth noting, that there could be many reasons, eg:
- dirty sensor,
- open or short circuit in the sensor,
- rusty wires,
- bad grounding,
- bent terminals, etc..
Computer diagnostics also allows you to identify malfunctions, responsible for increased toxicity of exhaust gases, such as:
- before or after ignition;
- limited catalytic converter conversion efficiency;
- fuel system leak;
- malfunction of electronic systems and sensors, косвенно управляющих системами двигателя автомобиля…
Knowing the possible sources of the problem, the service master can narrow the field of action, making troubleshooting much faster.
With the help of computer diagnostics, you can also check the brakes and other security systems. for example, a flashing airbag light may indicate a malfunction:
- driver airbags,
- passenger airbags,
- seat belt pretensioners,
- driver's side airbag,
- passenger side airbag,
- driver side impact sensor,
- датчика бокового удара пассажира…
How view, little information about the error itself. To solve the problem, special knowledge in the field of mechanics is also required..
Diagnostics before buying a new car
It's not just that car that's worth diagnosing, which you already have, but also that, which you are planning to buy. Before buying a new car, it is worth visiting a service station with it so that an expert can check it. Connecting the car to a computer before buying it will allow you to identify possible malfunctions and check the general technical condition, without parsing it. The test will reveal possible malfunctions of all vehicle systems.
Компьютерная диагностика также позволяет выявить “хитрости” недобросовестных продавцов, such as:
- speedometer reset;
- connecting non-working ABS controls to the oil pressure light;
- mounting emulators of broken systems;
- covering up a serious collision, computer fixed car (CrashData).
Computer diagnostics is a fast and non-invasive way to check the technical condition of the car and identify faults.. but remember, the computer test is only a clue to the mechanic about the nature of the problem with the car. Even the best diagnostic tools cannot replace human knowledge and skills., necessary for car repair. Carry out a quality running gear diagnostics, suspension and shock absorbers, engine and other systems you can in the Stop-and-Go service station: Kiev, Naberezhno-Pecherska road, 7BUT.
