Repairing modern vehicles is a rather troublesome task, which will certainly require serious financial investments. Therefore, many motorists prefer to do various small jobs like replacing relays, sensors, light bulbs, spark plugs, and so on, on their own. In order to promptly identify the problem that has arisen, special devices called auto scanners were developed. This design is a block with a special connector through which it is connected to the vehicle’s on-board computer. The scanner has special software installed, with which it is possible to decipher error codes and diagnose the malfunction.

Difficulty of the material:
Most modern Russian cars of the VAZ and LADA family are equipped with an electronic control unit, as well as an on-board computer. Thanks to such electronics, the use of diagnostic equipment is becoming increasingly important.
The presence of all kinds of sensors on important components (engine, electrical, gearbox) allows you to monitor parameters, as well as accurately determine the type of malfunction. All information read by such sensors is sent to the ECU, then the data is converted into numbers using standardized protocols and transmitted to diagnostic equipment via the OBD2 connector. Then, using the software, the parameters and values of the sensors are displayed on the external display.
The OBD2 diagnostic adapter reads and deletes errors , and depending on the capabilities and cost, such a car scanner can solve other problems, including chip tuning.
In this article we will consider and select suitable scanners for diagnosing VAZ cars, as well as programs for them. In addition, we will familiarize ourselves with the theory and provide recommendations for performing independent self-diagnosis.
Regularity of auto diagnostics
It is recommended to periodically, but at least once a quarter, carry out computer diagnostics of your car.
Programs for auto diagnostics via laptop
Computer diagnostics is impossible without the use of special programs that provide data decoding and display information. Below we will look at the main representatives of software for scanners.

What is checked during diagnostics, and on which cars is this possible?
LADA manufacturers are constantly improving their models, while simultaneously improving technical and technological equipment. The only exceptions are models without an ECU, before 1996.
Problems may also arise when diagnosing cars before 2000, but in any case, these models have a connector, you will need adapters (from 12 pin to 16 pin), or use a VAG 12 pin adapter cable.
Computer diagnostics are possible on the following VAZ models:
- 2104 - 2107 (including until 2007);
- 21053 - 21074 from 2010 (euro3);

Types of equipment used to check LADA
A list of diagnostic devices used not only in specialized car services, but independently, for example, in a garage. • Odometer correctors, with setting mileage values; • Models that support protocols, by reading information, erasing errors, codes are deciphered: ELM327 USB / Bluetooth / Wi-Fi running on the elm327 chip; • Vag adapter (cable) for later versions of the ECU and 12 pin pads; • Testers whose work is organized on the basis of oscilloscopes.
Diagnostic devices that support combination with ABS and SRS units, as well as using a CAN bus, are in demand.
Modern popular models
The best diagnostic scanners compatible with the VAZ have been selected for review. We pay attention to the following samples:
Scan Tool Pro
Scan Tool Pro is a compact adapter without an external environment, built on a universal microprocessor elm327 (basic) Chip version v.1.5 (PIC18F25k80). This diagnostic OBD2 scanner is used in conjunction with a laptop or smartphone; it has Wi-Fi and Bluetooth versions.
Engine control unit Lada Granta
As mentioned at the beginning of the article, Granta received new “brains” with CAN support (M74CAN). This innovation is capable of integrating “brains” with alarms and radios with a CAN bus.
They often install a “Standard” controller with Itelma number 11186-1411020-22: This ECU is not compatible with earlier VAZ models. In early VAZs, for example, Priora, the ECU came with a K-channel for data transmission.
Location of the ECU for Granta:
The “brains” are located at the bottom of the front panel, or rather under the glove compartment. It will be better visible if viewed from the passenger seat. The ECU is hidden by sound insulation and upholstery, so it will not be easy to get it out.
ECU firmware:
Serial firmware should indicate an optimized dynamic version for the 1.6-liter 8-valve Granta with an “M74” controller and an exhaust gas emission standard of “EURO-2”.
ECU chip tuning allows you to physically disable the second oxygen sensor (“lambda probe”) along with the catalyst. If this version of the firmware is implemented, this will lead to a significant increase in the dynamic capabilities of Granta.
To find out what firmware the control unit has, use the OpenDiag application, together with a diagnostic adapter connected to the OBD2 connector.
Methods for diagnosing ECUs and errors on Lada Granta via OBD2
Self-diagnosis
On Grant, the ECM with the M74 controller has built-in self-diagnosis that detects malfunctions. The ECM detects the problem, then the “Check Engine” light comes on and the error identification begins. Then the code is saved in memory and shown on the dashboard.
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.
Location of diagnostic connectors and recommended auto scanners:
| No. | Brand VAZ | Connector location | Suitable and recommended scanners + program |
| 1 | 2105, 2107 (with injector) | On the left side of the steering column | VAG-Adapter + Adapter 12 pin + OpenDiag Mobile |
| 2 | 2108, 2109 | Below the storage shelf, in the center. | |
| 3 | VAZ 2113, 2114, 2115 | In the cigarette lighter area, approximately 10-12 cm lower. | Scan Tool Pro + 12 pin adapter + OpenDiag Mobile |
| 4 | VAZ 2110, 2111, VAZ 2112 | On the right side in relation to the steering column, under the dashboard. | |
| 5 | Lada Priora, Kalina, | In the opening located behind the glove compartment. | Scan Tool Pro 2022 + OpenDiag Mobile |
| 6 | Lada Vesta | Located under the steering column on the left, on the left near the handle for opening the hood, under the mounting block | |
| 7 | Lada Largus | Inside the glove compartment on the back wall and closed with a protective cap | |
| 8 | Lada Granta | Right above the cigarette lighter. |

EconTool ELM327 for Nissan
EconTool ELM327 for Nissan is another one of the best diagnostic programs for OBD2. Intended exclusively for petrol Nissan vehicles up to 2008 (but also works with newer vehicles). It is free, providing the same options as other similar programs, but when purchasing the PRO version it opens up an additional feature: it allows you to read and reset errors.
Attention: the utility is not suitable for diesel Nissan models!
Depending on the type of design, a car diagnostic scanner can be:
Autonomous. In appearance it resembles a walkie-talkie. It connects to the car's diagnostic block and reads information directly from the electronic control unit.
Adaptive. This car scanner is small in size (up to 10 cm). It can be connected to any portable device. You can decrypt data using the Internet.
diagnostic scanner for home use. New models download software updates and drivers on their own. It's comfortable.
A scanner for a car can be of three types:
Dealer. This equipment is produced by the manufacturer. It's not cheap, but it offers maximum functionality. You only need to choose a scanner for your car brand; it is not compatible with other models.
Vintage. A professional device, its price varies from 300 to 1000 dollars. It is also used only for certain brands of cars, but there are fewer functions than at the dealership.
Multi-brand or amateur. The most common option for home use. A scanner for a car does not have to be selected individually for your car brand; these devices interact with most systems and are easily integrated into the control unit.
What else should you pay attention to if you want to buy a car scanner?
Number of functions performed. The better the software, the more tasks you can perform using the device.
Interface. The scanner should have a clear display and simple controls.
Connection. As a rule, via Wi-Fi and Bluetooth, but wired models can also be found on sale.
Important! If you are working with a professional scanner, carefully read the operating instructions. Such gadgets are often equipped with a “reprogramming” function, which can disrupt the standard settings of the on-board computer.
