Diagnostic connector for Lada Granta: where is it located?

The OBD port has been actively used in cars all over the world since the beginning of the 21st century.
The AvtoVAZ concern began installing an OBDII port in its models, starting with the Lada Kalina. By the way, before this period the tenth family had a 12-pin plug. Note: the Granta diagnostic connector does not require access devices, since it is quite possible to detect and use it blindly. For example, on a Lada Kalina, to connect, you should remove the plug next to the gearshift lever.

The purpose of the car diagnostic connector is to quickly exchange data with diagnostic devices. This makes it possible to both read and delete error codes and adjust some presets in RAM. In addition, it is possible to read the current value of the sensor identifiers specified on the Lada Granta. However, in order to be able to use these functions, you must first know where the diagnostic connector itself is located.

Search for OBD-2 on Lada Granta

Sitting on the front right seat, you need to find the glove compartment lid.
Place your hand underneath the lid and move it to the left towards the center console.
Your hand should now rest on the diagnostic connector.

As a visual reference, look at the vent cover located at the front passenger footwell. Above it is the plug we are interested in. By the way, it is not necessary to look at the port itself, since it will not be difficult to detect from the driver’s seat. The main thing is to know the place where you will be looking.

Grant diagnostic connector: where is it located?

The OBD port has been actively used in cars all over the world since 2001 . AvtoVAZ began installing OBDII on its models starting with Kalina - before that, a 12-pin plug was installed on the tenth family.

The photo shows an example of an installed ELM327 scanner.

The Grant diagnostic connector does not require tools for access - it can be found and used “blindly”. On Kalina, to connect, you will need to remove the plug near the gearshift lever.

Looking for OBD2 on Grant:

Sitting in the front right seat, we find the glove compartment lid;
Place your hand on the bottom edge of the lid and move it to the left to the center console;
Your hand will rest on the diagnostic connector.

As a visual reference, we look at the ventilation grille at the feet of the front passenger - the required plug is located above it.

It is not necessary to look at the port itself - it is easy to find from the driver's seat. The main thing is to know where to look.

Using the connector

The main options for using OBD-2 in the Lada Granta include:

connecting a scanner to check the machine and deal with errors;
installation/connection of an on-board computer, for example, Multitronics or State.

Connecting an on-board computer to a Lada Granta car will have a useful effect, because in this way it will be possible to:

monitor the engine temperature;
receive error codes as soon as they occur;
forcefully start the cooling fan.

How to use the diagnostic block

.
Directly to destination. To diagnose a car using an adapter that is connected to a computer or phone, or to a special diagnostic device. 2
.
For the purpose of having fun. Connect the adapter and install the Torque program on your phone, connect to it using a Bluetooth connection, and you can view the data online. And if you have a phone with GPS, then you can measure acceleration to 100 km/h, time to cover a section, etc. 3
. View engine temperature. Since the first versions of the car did not have an engine temperature indication on the instrument panel, many owners used a diagnostic connector to connect on-board computers, which show many parameters, including engine temperature. And since most Grant owners complain about the low operating temperature of the engine, on-board computers are a very popular solution to this problem. Self-diagnosis allows you not only to find errors present in the unit’s memory, but also to save the owner financial resources. To implement the process, you can use a regular laptop, the memory of which already contains a pre-purchased scanning program. Within 1-2 minutes, this software will check the car system and provide results for all parameters of the engine and other components, and indicate where the fault is located.

Self-diagnosis Grants

To diagnose the Lada Grant, a standard K-Line adapter is not enough. It provides for the installation of an electrical control unit of a different configuration than on other VAZ vehicles, and it requires a special adapter. Today, the most popular is the use of the ELM-327 diagnostic adapter and various software for it, for example, ScanMaster, Torque.

It’s worth looking at what the ELM-327 adapter looks like in specialized literature or on the Internet.

Specialists on official servers use the dealer scanner DST-14T. It is unlikely that you will be able to perform diagnostics on Grant yourself, since this is not a simple procedure. It includes software and hardware components, and not just connection via K-Line. It is important to be able to compare the device readings with real circumstances.

Advantages of an auto scanner

“Scanmatik-2” was appreciated even by professional diagnosticians. Having tried this kit once, car enthusiasts were pleasantly surprised that for a relatively low price it allows you to work with a full fleet of domestic cars and an impressive part of foreign ones. When working with the diagnostic kit of this model, you can also use a wireless interface to connect the system to a computer (Bluetooth).

The OBD-2 connector on Grant regularly supplies power to the diagnostic adapter. In extreme cases, the Scanmatik-2 adapter can be powered from the cigarette lighter. In general, the device is very convenient for performing diagnostic procedures yourself. It even has surge protection. If, for example, you apply current from the cigarette lighter when the system does not need it, nothing bad will happen.

Every device has pros and cons. Many car thieves know how to use the diagnostic connector for their own selfish purposes. As a rule, the diagnostic block is used by criminals to disable the standard immobilizer. A common solution to this problem is to replace the standard block with a “re-pinned” one, with a different arrangement of contacts.

The adapter consists of a “male” (fake connector) and a “female” (standard connector), which is previously removed. It will not be possible to connect standard diagnostic equipment to the new connector without such an adapter, but the chances of saving the car from theft are increased. That's all. Good luck!

Electric power steering

When the EPS diagnostic light comes on or the electric power steering switches on/off after a certain period of time, you first need to check the EPS using the diagnostic connector. Open Diag (application) together with an OBD-2 adapter or scanners will help here:

Scanmatic;
Motor Master;
ScanDoc.

The diagnostic process is designed to indicate where errors are located and decipher them for further repair based on the type of malfunction. In addition, it is quite possible to perform the check without a scanner:

There is an 8-pin connector (black) under the ignition switch under the steering wheel. It is necessary to dismantle the casing at the steering column (unscrew the fastening screws from below).
Insert the paper clip, closing the two contacts.
Turn on the ignition and observe the warning lamp.
The first signal will be the continuous burning of the lamp (“1”).
It is necessary to count subsequent short signals, that is, if there are 3 short ones, then “3”.
In our case, the code “13” should be formed.

Frequently asked questions about auto diagnostics via a computer or smartphone

Engine diagnostics

The capabilities of engine diagnostics via the OBD2 connector depend on the scanner and software. For example, a simple amateur adapter ELM327, together with the OpenDiag application on a smartphone, allows you to read engine errors and decipher them, as well as view temperature sensors and engine speed, both at idle and while driving in real time.

We provide documentation for engines with electronically controlled throttle valves that meet toxicity standards. Read the files by running engine diagnostics.

ABS diagnostics via OBD2 connector

If problems arise with the ABS, before changing or manually diagnosing the problem, read the errors according to the instructions provided. Checking for errors will show you not only the condition of the sensors, but also the wires and connectors.

Diagnostic kit Scanmatik-2

Diagnostic kit "Scanmatik-2"

There is also a Scanmatic-2 diagnostic kit available for free sale, which is quite suitable for the Granta connector circuit (a laptop is required). A diagnostic program is also included in the kit. On the manufacturer’s official website, the price for the set is 13,700 rubles. Car enthusiasts call this system the best for domestic cars. Suppose you need to do the diagnostics yourself. First, load the laptop and install the desired program. Next, connect the USB cable to the computer. Go to Windows Device Manager. A new COM port should appear there.

We are waiting for the Scanmatik diagnostic program to start. We set the above-mentioned port in its settings. We connect the adapter to the diagnostic connector using the OBD-2 cord (OBD-2 and USB cords are connected using the included adapter). The OBD cable indicator LED should glow green if the connection is established correctly. After connecting in the diagnostic program, you need to open the “Engine” tab and click on the “Auto-detection” button. The diagnostic program will search for the “brain” of the car engine.
