It's no secret that the most reliable way to identifymalfunction is computer diagnostics of a car. Thanks to the use of special tools, it is possible to accurately determine and even prevent a malfunction in any part and system of the machine. And so that computer equipment can read data and determine error codes, there is a diagnostic connector inside the car. About him and will be discussed today.
Внешне диагностический разъем («Приора ВАЗ» в том including) resembles a kind of outlet, which is connected to a special wire connecting the car with computer equipment. And this cord is not simple, but diagnostic. It costs a lot of money - about 4-5 thousand rubles. If you connect a conventional wire from an extension cord, you cannot get any data. We will talk about them a little later, and as for the connectors themselves, each manufacturer completes their cars with different devices. All of them differ in their form and are placed in the cabin in different ways. And if the computer equipment can be connected absolutely to any car, be it “Lada Grant” or “Outlander”, then the diagnostic connector and plug must be purchased for each car.
In the car system, it is simply indispensable.Without this device it is impossible to make a full diagnosis, even if you have a plug and software. Connect all this stuff will be nowhere, so the connector must always be in good condition. It is a connecting node that transmits information and error codes from the computer through the cord to the screen of the monitor of diagnostic equipment.
All automotive connectors are manufactured onindividual workshops using special technical tools and equipment. Black ABS plastic is often used as the case material on such products. The pin connector conforms to the OBD II standard. Silver or tin is applied on top of it. The latest material is most often covered diagnostic connector VAZ and "Volga". All these devices are manufactured on a special mold using special technologies.
To date, there are three main cords that are connected to the diagnostic connector:
All of them are equally effective and can transmit information with high accuracy. Unlike connectors, cords can be used on several vehicles, that is, to be universal.
It is worth noting that the more car is equippedelectronics, the more expensive its diagnostic equipment. So, the price of connectors for imported cars is about 5-10 thousand rubles. 2 times cheaper are the devices for modern VAZs of the Priory and Largus type. The cheapest diagnostic connector is in the old Volg and the VAZ classics, although it is not clear why they are needed there and how they relate to computer diagnostics. They cost from 140 to 300 rubles, but considering how Soviet machines were stuffed with electronics, there is no use for them.
