List of programs for ELM327 adapters. This page presents free programs for car diagnostics using the elm327 adapter. All elm327 programs are divided into groups depending on which device you will be running diagnostics on. There are programs for a computer or laptop (Windows), elm 327 programs for android devices (smartphone or tablet), for iOS (iPhone, iPad), as well as for smartphones based on Windows Phone. Thus, in this section there are programs for any device and for any type of ELM327 adapter, be it USB, Wi Fi or Bluetooth adapter.

All elm327 programs are sorted by ease of use and functionality. Those. The higher the program, the better it is and the more recommended it is for use. If the application from the beginning of the list does not suit you for some reason, or they do not support your car, try the following programs.

Why do you need car diagnostics?

To put it as simply as possible - in order to understand why the alarming yellow or, even worse, red light on the instrument panel came on. Namely, an indicator indicating a sudden breakdown or malfunction of the engine, transmission, fuel supply system, ignition, gas distribution, air conditioning, etc.

All these processes in the car are controlled by an electronic control unit (ECU). It collects data from several dozen sensors, processes it and transmits commands to executive nodes. In case of malfunctions, it is signaled by an indicator, for example, Check Engine.

To understand which component or unit is damaged, the car is diagnosed using an Android application or a computer program. This service is successfully performed at any service station, but you can also do it yourself. Save a few thousand rubles, at a minimum.

In our opinion, it is possible to use Android or IOS based applications for car diagnostics. However, if the scan produces serious error codes (a malfunction in the engine or transmission), it is advisable to repeat the procedure with professional technicians.

For scanning, you can also use special devices, for example, an inexpensive multi-brand Rokodil ScanX scanner.

The main advantages of this particular adapter are its compatibility with most cars produced in 1993 and accurate diagnostics of all components and assemblies. It is also worth noting the presence of Bluetooth version 4.2, which will allow you to connect the device not only to Windows or Android, but also to iOS

Passenger

The passenger version of the Lada Largus (R90) is a car for towns and rural areas, designed for out-of-town travel and for business trips. It is suitable for daily trips around the city, as well as for long trips; transportation of large cargo is also not difficult. The car has a larger internal size, which allows the use of an additional row of seats, while maintaining comfortable seating for up to 7 adult passengers. Thanks to the folding seats, the Lada Largus can simply be transformed into a car for a family tourist trip.

Cargo

Van model Lada Largus (F90) - can be used to transport goods around town or rural areas; This modification of the car is aimed at people who are engaged in commerce.

From an engineering point of view, the body of the Lada Largus car is manufactured at the world level. After hardness tests, it was found that the base of the body has a hardness of 18,000 Nm/degree. This is a very good result for a car of this model. The body system meets European safety requirements.

Power units

The Lada Largus car is equipped with 2 types of power units from Renault - a 16-valve and 1.6-liter engine with a power of 77 kW with a manual 5-speed gearbox and an 8-valve 1.6-liter engine with a power of 64 kW. All engines meet the highest environmental requirements of Euro 4.

The main plastic parts for the car will be supplied by foreign companies: front bumper, door trim, device panel, moldings, etc. These suppliers deliver the main parts for Renault, and then they will supply parts for other AVTOVAZ cars, which are manufactured in Russia on the B0 platform.

How to use such programs?

In defense of programs for reading car errors for Android, we emphasize that they are much easier to use than software for a PC. How is the scan carried out?

• Make sure that your smartphone has a Bluetooth module;

• Download the car diagnostics application for Android in Russian (below we provide a list of the best);
• Scanning is carried out using a special connector (scanner, adapter), which is connected to the car via the OBD 2 connector. The output is designed to transfer data from the car’s on-board computer to software for reading error codes (a program on a PC or a smartphone with Android). The scanner is connected to the operating system of the head unit via Bluetooth or Wi-Fi (the first is preferable). The adapter is quite inexpensive - about 1500-3000 rubles, you can also order it for $10 from Aliexpress. Scanners with the elm327 chip are very popular; they integrate perfectly with programs for car diagnostics via Android.

• So, the adapter is connected to the OBD2 port. The connector is most often located under the steering wheel, but can be moved to another sector. The shape is trapezoidal, with 16 contacts (difficult to confuse with something else).
• After connecting the scanner to the connector, you should synchronize it with Android. Turn on Bluetooth on your phone and start searching for devices. Once the OBD2 module is detected, connect to it. If prompted for a password, enter 0000 or 1234 (or look for the password in the scanner instructions);
• Now start the car;
• Launch the car diagnostic program for Android in Russian;
• Further actions depend on the program, but, in general, all you need to do is run the diagnostics and wait for its results;

• The latter are issued in the form of codes. To check errors, you need to decipher them using tables from the Internet or in the program itself.

How to use

Before purchasing an adapter, make sure it is compatible with your car. After purchasing the adapter, it is important to correctly connect the scanner to the connector. As a rule, the OBD 2 connector is located in the passenger compartment under the dashboard. Models before 2006 usually have a 12 pin connector (GM), and to connect the scanner you will need a 16 pin adapter.

Information on the location of the connectors is presented in the table and photo below.
