The information presented above (how to diagnose a car yourself) is only a slightly open door to the world of computer auto diagnostics. Improvement electronic devices Car maintenance requires the driver to be able to identify faults on their own, because this not only saves money, but also prevents serious breakdowns. Yes, you can contact a car service or service station and fix the problem. Sometimes you have to do this. But at least you can find out where the breakdown is so that you can talk to the mechanic in an understandable language.
Let you first learn how to read error codes from the on-board computer. The next stage of development may be an increased understanding of the diagnostic process, which could become a source of business. After all, auto diagnostic services have become in demand.
New on-board computers contain information about the operation of absolutely all components and mechanisms. A modern driver must be able to work with car scanners and software, which are described in this article.
Nowadays, every car, even if it is presented in a minimal configuration, has an on-board computer. There are also numerous electronic devices in the form of sensors that monitor the state of all systems and, in case of malfunction, signal this. However, it is extremely difficult for an ordinary user to figure out what’s going on based on an error code or other not entirely clear information. Therefore, you often have to send your car to a service center, where they can tell you the cause of the breakdown. The car diagnostic program is an excellent help for those who want to independently understand the cause of a breakdown or error and not go to a car service center, wasting their time and money. Special scanners are used for this. OBD 2 - devices that can be connected to on-board computer car. Then they connect to a laptop, tablet or smartphone, on which the same program for car diagnostics is installed. Integration occurs through USB, Wi-Fi or Bluetooth.
Necessary components for self-diagnosis of a car
To check the electronic component of a car, you need to have three components available: a device like OBD 2, one of the above gadgets and, in fact, the program. Popular ELM 327 and a number of other devices like OBD 2 are equipped with their own software. But it has a number of disadvantages. For example, programs for diagnosing an ELM327 car are extremely complex and incomprehensible to the average person who does not have special knowledge to the user. They are not adapted for the Russian-speaking user and are often simply unfriendly, which cannot be said about third party software. Free programs for car diagnostics can be found on the Internet. Now it is possible to download many of similar applications on any platform, from Windows to Mac OS and Android . This article will talk about the most popular and successful solutions for all current operating systems. Therefore, anyone can easily choose what suits them best.
The best programs based on iOS devices (Apple products)
iPhoneApplication
This program is now the most popular among all aimed at iOS . There is the possibility of diagnosing a car using i Phone and iPad.

An absolute plus is mobility, thanks to which you are not tied to a specific place; you can scan your car anywhere and at any time. Also very solid functionality: the ability to scan the gearbox, temperature indicators, oil level, airbag status and much more turns your smartphone into a powerful vehicle control center. We can agree that this is very convenient: nothing superfluous, except for two phone buttons.
DashCommand
Undoubtedly, worthy program for car diagnostics - the same excellent functionality as its older brother in the camp iOS . A friendly and beginner-friendly interface - what the built-in programs lack, is present here, which cannot be ignored. Interestingly, this program even has an automatic calculation of the cost of the trip, for which you only need to enter the cost per liter. This program is also compatible with other operating systems; in particular, it can be downloaded for Android.
Both programs can be found in i Tunes . But there is one small drawback. It lies in the fact that the program is not adapted for Russian-speaking car owners. However, it is intuitive, so this minus may seem insignificant.
Android application: Torque
This car diagnostic program is the absolute leader among systems on Android . With its help, you can easily diagnose a car by installing the program on mobile device By Bluetooth communications. It has very wide functionality, which makes it a flagship in its segment. Speedometer, tachometer, torque - all this can be checked in real time without any problems. Very user-friendly interface and many up-to-date functions make this application best when used Android . A special and pleasant nuance will be support for the Russian language, which will make diagnosing and managing the program’s functionality even easier.
The best Windows programs
ScanTool
It is impossible not to say something about this kind of programs in general. Even though they Lately are outdated, but they still have certain advantages in front of their mobile brothers. The main thing, perhaps, is security. That is, if someone wants to hack the device from the outside, it will be much more difficult for them to do so. USB cable is safer than wireless connections, because the attacker needs to directly penetrate the car’s interior.
Scan tool - a program for which is the best on this operating system. No wonder it is the most popular. The advantages of this program: intuitive interface, very broad functionality, large database where the decoding of all system errors, there is support for the Russian language.
MyTester
The peculiarity of this program is that it is specialized for domestic cars. IfIf you need a program for diagnosing a VAZ car, then this application will best choice. Wide functionality and support for the Russian language are positive aspects programs.
This article presented all best programs for vehicle diagnostics for any system and any requirements. Having familiarized yourself with them, you can easily find faults without contacting a car service center.
Our technical support
.
