Programs for free diagnostics of Russian cars

FiatECUScan

The FiatECUScan program is intended for car enthusiasts who want to diagnose electronic control units (ECUs) of cars produced by Italian companies Fiat, Alfa Romeo and Lancia via the K-Line or ELM327 interface.

A selection of programs that give car owners the opportunity to independently diagnose them, without contacting service centers. Here are the easiest to use applications, which, however, require the user to have at least basic knowledge about the device of the car. All programs from the selection work only with a special adapter that reads data from vehicle electronic control units using the OBD II protocol. Similar adapters can be purchased on online trading platforms, as well as in automotive stores. Usually they have a fairly “democratic” price, not comparable to the cost of service at a service station.

First of all, we recommend the OBD Auto Doctor program - it is a universal tool that works with a wide variety of makes and models of cars. The program reads error codes from the ECU, deciphers them and allows you to reset them with one touch. It can also display the dynamic parameters of the vehicle in real time and promptly report problems. If necessary, OBD Auto Doctor even allows you to turn your Android device into an on-board computer.

Another solution with similar functionality is Car Scanner. This is one of the most intuitive diagnostic wizards that works even with the cheapest Chinese adapters and collects much more information than its analogues. Also among the advantages of the application, we note a well-organized interface and a minimum number of restrictions in the free version.

Whatever they say about foreign cars, VAZ is the most famous and popular brand in Russia and the CIS countries. The attention to him is special. Whether it’s a “bucket with nuts” or not is a separate issue. In this article we will touch only on the applied aspects related to the diagnostics of cars on the assembly line of the Volzhsky Automobile Plant. In particular, software.

Types of ELM327 auto scanner for diagnostics

The ELM327 auto scanner interacts with the OBDII system and transmits data from the on-board computer to the device. Works through:

• USB connection;
• wireless WiFi;
• bluetooth

To work with the scanner, you must install a special application. Utilities are divided into types, depending on the device for their installation.

What cars is the scanner compatible with?

To determine which car scanner is suitable for a personal car, it is enough to determine the data exchange protocols. To do this, you need to look at the OBD-2 block and clarify which contacts are present on it:

• The presence of pin 7 (K-Line) indicates that the ISO 9141-2 protocol is used for diagnostics. Such diagnostic connectors are used in cars made in Asia and Europe.
• Pins 4, 5, 7, 15 and 16 indicate the ISO14230-4KWP2000 protocol, which is commonly used on Daewoo, KIA, Hyundai, Subaru STi and some Mercedes models.

Android programs

All programs for diagnosing Russian cars for Android support Bluetooth, Wi-Fi, USB. Compatible with ELM327 scanner.

Meaning and decoding of codes

During self-diagnosis of a VAZ 2115 with an injector, only numbers or flashes that code the error will be shown on the instrument panel. When reading trouble codes from an electromechanical instrument cluster, it is necessary to record the number of flashes and calculate error numbers from them. Their purposes can be deciphered using a special list. Most of these faults can be resolved independently by replacing failed sensors.

Self-diagnosis codes

When performing diagnostics, it is necessary to take into account that the number on the screen may indicate two summed errors. For example, 9 indicates the presence of two faults - numbered 1 and 8.

An example of error 14 appearing on the panel

Table of decoding codes for flashes calculated during diagnostics.

The data obtained allows you to quickly find the faulty element and eliminate the cause of the error.

The video from the Garage channel shows diagnostics on a VAZ 2115 using a scanner and laptop.

Controller errors

The most common controller errors encountered during diagnostics are listed in the table.

Reset errors

After self-diagnosis, finding out the cause of the problem and correcting the breakdown, the errors can be reset.

To do this, go to the error viewing menu, press the odometer reset key and wait a few seconds. The number 0 will light up on the screen - the error has been reset. In this case, data about problems is stored in the unit’s memory and must be deleted. If left, the “Check Engine” light will light up in the instrument cluster. In addition, self-diagnosis may not read all electrical system errors; the error removal procedure will show whether a more detailed analysis of the vehicle’s electronics is needed.

To reset the error, do the following:

If the symbol remains illuminated, there is an ongoing problem with some sensor or wiring in the vehicle. It can only be found out using a special scanner. It is necessary to conduct additional diagnostics to determine the problem node. Then carry out repairs and clear any existing errors using a computer diagnostic program for the ECU.

Resetting errors on cars with an electromechanical instrument cluster is carried out by disconnecting the negative terminal of the battery from the on-board network for 10 seconds. The ignition must be turned off.

Programs for iPhone

Utilities for installation on iOS support Wi-Fi, which is very important when diagnosing from an iPhone. There are few such developments, but they are quite functional.

InCarDoc IPhone

Only suitable for vehicles that support OBD-II function. Works in real time.

Diagnoses parameters:

• speed;
• fuel consumption;
• revolutions;
• pressure.

Reads errors, saves parameters, clears errors. Determines the VIN number of the body, determines coordinates with GPS support. You can install the program by downloading it from the App Store.

Engine Link

One of the most popular utilities for iPhones. Works with many cars. There is a diagnostic function for diesel engine control units. Suitable for reading by ELM327 scanner (Wi-Fi version). What the program can do:

• tests emissions;
• work in real time;
• reads and resets OBD fault codes;
• displays sensor data and engine characteristics;
• MPG to calculate fuel consumption in real time;
• Full custom PID support.

Supports OBD-II and EOBD. To use the program, you need compatibility with ELM Bluetooth Low Energy (for iPhone 4 and later versions) or a Wi-Fi adapter.

Additional work

For more detailed diagnostics, inspect the car for body damage. Be sure to check the level of all technical fluids. Inspect the suspension and steering for any play. Compression must . Its values ​​should range from 9.5 to 11 atmospheres.

In this case, the readings of all cylinders should be approximately the same. The significant difference between them serves as a reason to take a closer look at the motor. You also need to check the condition of the battery . The voltage should be about 12.7 - 13.5 V (it varies). As an additional check, it would be useful to check the valve adjustments. Clamping one or more valves will result in an engine power error. To avoid digging up the injector in vain, it is better to check the condition of the valves in advance. Check the functionality of the spark plugs and high-voltage coils (high-voltage coils).

How to connect to iPhone or iPad

To get your own diagnostic center to check the operation of a vehicle, it is not necessary to connect to the scanner via Bluetooth. More modern ELM models are equipped with a Wi-Fi module, which allows you to use almost any portable device to receive data.

Let's look at how to establish such a connection:

• Connect the scanner to the connector in the car.
• Go to the section responsible for wireless connection settings and select the “CLKDevices” network.
• There will be a blue arrow on the right that you need to click on.
• In the window that appears, you need to enter the IP address and router information: 192.168.0.11. You also need to specify the standard subnet mask: 255.255.255.0.
• Just below you need to specify port 35000.

This completes the setup. Knowing how to use the ELM 327 scanner, it is enough to install any application for quick diagnostics and enter the same IP and port parameters in its settings.

However, it is worth considering that difficulties may arise when setting up private scanners.

Difficulty connecting the adapter to the VAZ ECU

VAGCOM, K-Line adapters are designed for direct connection to the ECU via a 16-pin OBD-II connector. It began to be installed on VAZ cars after 2002. Some models are equipped with a 12 pin connector. It is not compatible with the adapter connector. The solution is simple: purchase a GM12 adapter or a K-Line adapter in an OBD1 (GM12) housing.

Programs for diagnostics of VAZ 2107, 2108, 2109, 2199, 2110, 2111, 2112, 2113, 1214, 2115

What programs and scanners are used to diagnose a VAZ with a GM12 and OBD2 connector?

The programs for diagnosing VAZ are completely different, but they often use programs that are different from each other, and the point here is not even the year of manufacture of the car or the shape of the connector, be it GM12 (also called OBD1) or the usual OBD2. The point is rather that cars with a GM12 connector are more often diagnosed with a scanner manufactured by the Russian company Master Kit BM9213M or its analogues. And newer cars are more often diagnosed with the ELM327 scanner. For this reason, let's talk a little about scanners.

The BM9213M scanner is quite suitable for OBD2 diagnostics, but the ELM327 scanner is more often used for this connector. Programs for diagnosing VAZ may be the same to work with both scanners.

Scanner for diagnosing VAZ, Lada and other brands of cars with OBD2 ELM327

To make it at least a little clearer, the ELM327 can be used without problems with VAZ cars with Bosch ECU firmware 7.9.7, which has been installed since 2011. To operate this scanner with cars with lower firmware, you need to use a special pinout of wires from the connector to the scanner or another scanner, for example BM9213M. To learn how to connect the ELM327 to a car with firmware released earlier than 2011 or with a GM12 connector, as well as the programs used for this, see the video below

ELM327 is still the most universal scanner currently produced, suitable for diagnosing the entire family of VAZ cars with injection engines - 2107, 2108, 2109, 2199, 2110, 2111, 2112, 2113, 1214, 2115
