Selecting and installing an on-board computer on the Lada Granta

Description

The on-board computer on the Grant is easy to select and install. This car has an OBD-2 diagnostic connector, to which the BC is connected using a standard connector (usually included in the kit). There is a model BC State x1, which are installed instead of a button plug in the panel. The connecting wires are connected to the diagnostic block (located near the front passenger's left leg). Universal on-board computers are installed on the dashboard or windshield. There are also models installed instead of a radio.

This is the best thing that has ever been created in Togliatti. Harmony, originality, budget price - this is the Lada Granta 2190. The car replaced three “classic” models - VAZ 2107, Kalina and Samara. Not a high price is the main priority of this model. To do this, the company used technology that allows you to reduce the number of parts that make up the car. For example, the front part consists of only three parts, and the instrument panel consists of 40 parts. The Lada Granta is 22 centimeters longer than the Kalina and has 5 mm less ground clearance. The car is already arousing great interest, and the queues for it are huge.

It would take a lot of time to list all the advantages of the car, but still, how can we not mention the spacious interior and beautiful modern panel from Renault Logan. There is enough space for a tall driver, there is enough space both above the head and on the sides. The seats are better in shape and design, and have an upright seating position. The same front panel now has a stylish dark color, round ventilation holes, and laconic shapes. The steering wheel contains three spokes, just like foreign cars.

The doors also acquired a more complete composition and meaningful design. The beautiful door handles finally began to resemble themselves. Large side mirrors provide good visibility, and this is very important for drivers. It will probably be interesting to many, but it was in the Lada Granta that another interior detail appeared, which had never been on VAZ cars before, these are two cup holders.

The package can be found in three versions: Standard, Norma, Luxury. The “Standard” kit contains manual windows and unpainted bumpers. And the “Norma” kit also contains an airbag for the driver, an electric tailgate, an on-board computer, and an alarm system. The “Lux” package contains full power accessories, heated mirrors, air conditioning, heated front seats, airbags, ABS+BAS. Each configuration has its own engine, all of them with a volume of 1.6 liters, but with a power of 80, 90, and 98 horsepower.

Whatever one may say, the Lada Granta is a modern car, which is distinguished by a spacious interior, a new panel, seats, and a large trunk. And although technically the car is far from perfect, it is a new and most importantly affordable product.

State Uni Comp 620 in Lada Granta

The “simplest” on-board computer for the Lada Granta is the BC STATE X1-G. It is compatible with ITELMA M74, M75 units, as well as BOSCH ME17.9.7. The connection is made to the OBD connector, which is located in the cabin. No additional power is required. We will look at how to install it, as well as how to update the firmware. Sometimes you need to update it immediately to get compatibility with a new car. Therefore, read the review carefully.

Alternative installation option for Lada Granta

Know that the on-board computer on the Lada Granta can be installed in a non-standard way. The idea is to “hide” the wires.

Second connection diagram

Let's implement the scheme shown in the photo. Let's take the power and ground from the emergency light button, and let everything else be standard. Connect to the button wires and use T-connectors for this - they can withstand a current of 100-200 mA (which is what is required).

So we had to remove the hazard warning button and connect to two wires. Then we run the cable to the OBD connector and use the terminals included in the kit.

The wires will be invisible

The standard connector (terminal block) had to be disassembled. But how great everything looks now!

We update the BC firmware ourselves

First of all, you will need to buy a USB-K-Line adapter. The software you will need is firmware, a program to install it, and a driver for the adapter. If you already have all this, assemble a diagram as in the photo.

Only three wires are used

Note that toggle switch T1 is closed “at the request” of the program itself. The rest of the time it will be open.

A computer can also act as a power source - just connect to the Molex connector. And for the BC, a terminal block removed from a computer cooler (2 pcs.) is suitable.

Update process

First, connect the adapter to the USB port. Install the driver. Make a note of which “virtual COM port” will be used. Then proceed like this:

1. The program is launched for execution. Select the firmware (the “Folder” button);
2. Select the COM port number (the “Port” button);
3. Press the button with the lightning bolt. The message “Turn on power” will appear. On the BC press any key and then close the toggle switch.

The procedure will take a couple of minutes. A progress bar will be shown in the window.

Where can I download the software?

Let's say we want to buy an on-board computer for the Lada Granta, not flash it. Go to the website and select the desired category. Then we find our BC (X1-G), click on the photo and see the product page. It will contain a link to the program and the firmware file.

The situation is more difficult with the driver. We need a USB-COM driver. If you purchased an adapter with a “BM” chip, do the following:

1. Go to the manufacturer's website ();
2. Open the “Drivers” tab;
3. Go to the “VCP Drivers” tab;
4. Select the required file (there are versions for different OSes), download it.

About energy consumption

The BC STATE model X1 G consumes 0.015 Amps when in standby mode. The rest of the time the current can reach 200 mA. In practice it is difficult to obtain a value exceeding 170-180 mA. For comparison:

• Good (expensive) signaling, standby mode - 10-15 mA;
• Conventional signaling with a key fob - 25 mA;
• Alarm in the “Disarmed” mode – 100-300 mA.

In general, our BC is quite “gluttonous”, but not as much as an alarm system.

Functionality on board the vehicle

The manufactured models of onboard vehicles for the Lada Granta have a wide information memory and are equipped with a monitor. This significant advantage is beneficial even for drivers with poor vision and women who are not very confident in the functioning of the car. In this regard, the on-board computer can help the car owner. He points to:

• travel time;
• fuel consumption at different speeds and driving rates, up to a liter;
• average speed levels and gasoline costs per trip;
• residual quantity in the fuel tank;
• speed when starting the car;
• speed when driving until the engine is completely warmed up;
• engine heating level to avoid overheating;
• various problems with Lada mechanisms;
• timely heating and drying of candles;
• temperature in the cabin and outside.

In addition to these functions, the on-board computer on the Lada Granta has volatile memory, a malfunction indicator, a supervisor (warning about unplanned vehicle movement, unswitched headlights and direction indicators) and afterburner. The latter resets the memory when switching to the gas pedal when accelerating the Lada to its original settings when using gasoline no lower than 95.

The standard on-board computer of the Lada Grant, namely the State X1 M (Multi-Set) model, is considered the highest priority on-board computer for the Lada family. Compact dimensions allow it to be built into the instrument panel in the recess of the button cover. If a car owner wants to buy a State on-board computer, then, in addition to the device, the kit will include instructions and wiring.

The filling of the State X1 M model consists of a built-in trip computer, in which all the necessary information on the operation and diagnosis of Lada mechanisms will be processed.

A diagnostic tester can provide a lot of information about the car's condition.

Basic functions of the device

Installing a radio in the
Lada Granta On-board drivers for the Lada Granta have high information memory and a small monitor, except for the “State” model, which only has a digital display. This makes it easier for people with poor eyesight and those who are unfamiliar with the nuances of engine operation to monitor all the processes that accompany its stable operation. BC will help the car owner by pointing out the following parameters:

• total travel time;
• detailed fuel consumption at different speeds;
• average speed indicators and excessive fuel consumption;
• remaining fuel in the gas tank;
• speed of start of movement;
• engine temperature;
• malfunctions of components and mechanisms;
• temperature inside and outside the car;
• on-board network voltage;
• crankshaft rotation speed (engine speed).

The on-board computer has a volatile memory and the ability to control the anti-theft system - the Lada Granta immobilizer. The on-board vehicle has a built-in supervisor, a fault indicator, and a “afterburner” function - the ability to reset the memory after starting the engine.

The functionality of even the simplest on-board computer is much broader than the standard one installed on the Grant. The discrepancy between the readings of the factory and alternative devices can reach more than 30%.

Some on-board drivers can additionally control lighting, stove operation, clock, calendar and alarm clock, and automatic window closers. You can plan your trip route based on the BC readings. It also allows you to use various navigation installation options and can warn you about low fuel levels or exceeding the permissible speed limit.

Most devices allow you to independently diagnose the operation of different car systems. The device can read ECU error codes without using any equipment. The explanation is presented in the accompanying documentation for each device. Such functionality will allow you not only to save on a trip to a specialized center, but also to identify problems, preventing serious malfunctions from occurring.

On-board unit installation

If you buy a State device for a Lada Granta after purchasing the car itself, you can install it yourself. At the same time, you do not need to worry about the supposed “failure” of the warranty of the purchased car, since the Lada panel has a corresponding connector for such an on-board device. When installing it, the panel will not be disturbed or damaged.

The on-board computer is installed by releasing the recess in the panel from under the button cover. The State on-board computer with the wiring already connected to it is inserted into the freed niche. The end of the wiring is brought out and connected to the diagnostic block below, near the passenger seat, where the passenger's foot is usually located.

Not too high a price, compactness, ease of use, ease of installation - these are significant factors for buying a State on-board computer for a Lada and making the operation of the car completely convenient and safe. A video on how to operate the on-board computer will help you get acquainted with the device in more detail.

However, the VAZ 2190 car can be equipped with other similar computer installations, for example, Multitronics routers. Their various modifications are considered universal, since they allow the driver to attach and install them in places where it is convenient for the car owner (on the windshield, inside, on the panel, etc.).

During installation, you will need to remove the dashboard to cut the appropriate hole.

Installing the Multitronics on-board computer on Granta in the Din-place (in the panel) will be complicated by the fact that here you will have to very carefully route the wiring to the diagnostic block. In this case, it will be necessary to remove the dashboard and make holes for the wires. In this case, it is convenient to use a heated knife to minimize the deformation of the panel. The wires must be secured in the panel itself to avoid the noise they make when the car is moving. It is better to secure the on-board computer to the panel with liquid nails.

After the on-board connector is connected to the diagnostic block, it is necessary for the computer to identify all on-board settings. If this does not happen within a certain time, it is necessary to change the computer firmware so that it supports the CAN protocol. Therefore, this will require reflashing the Multitronics, and this is already a significant disadvantage.

Computer capabilities State 219 X-6 Grant

Like any State computer, this on-board computer has a number of important and useful functions that help the car owner in operating his car. These features include the following functions.

Tropic

Tropical function to adjust the temperature at which the cooling fan turns on. Particularly important in hot summers to prevent engine overheating.

Working with HBO

MK State 219 X6 is designed so that it can work with cars that have LPG installed. To accurately display the readings of an engine running on gas, the computer settings provide correction of the flow rate when running on gas.

Software Update

If necessary, the owner of this bookmaker can update the software. All the necessary information on how to do this is indicated in the instructions for the State 219 X-6 and on the manufacturer’s website.

BC State 219 X-6 is installed on VAZ 2190 (Lada Granta) and VAZ 2117 (Lada Kalina-2).

Versatile alternative

Of course, thanks to their various mounting locations, Multitronics on-board routers can compete with the States. Powered by a 32-bit processor, multitronics are precise and fast in operation. If a car enthusiast has the opportunity to buy such an on-board computer, then the car will be under excellent control thanks to functions such as:

• a large number of diagnostic protocols, including extended ones;
• transfer and save all driving statistics to a personal computer;
• voice accompaniment;
• parking radars, etc.

All of the above functions of the State on-board vehicle have been added to the multitronics. In addition, the latter have easy setup for operation and a convenient user interface. But due to all this, the price will be much higher than that of a compact and more suitable State Grant.

Initially, it was possible to buy on-board computers for the Lada Granta only from the official one. Since sales of this car started at the end of 2011, for some time the unavailability of additional equipment for the Lada made it not very popular among car enthusiasts. However, it is now possible to buy on-board computers for Grants from official dealers and various suppliers of automotive products and equipment.

EUR - electric power steering

If the EPS diagnostic light comes on or the EPS periodically turns off/on, you should first check the electric power steering through the diagnostic connector.

The same Open Diag application, together with a diagnostic OBD2 adapter, will help with this, or

other scanners: Scanmatic, ScanDoc, Motor-Master. The diagnostic process boils down to identifying errors, decoding them and further repairs according to the type of malfunction.

The check can also be performed without a scanner, in this way:

1. Under the steering wheel, near the ignition switch, you should find an 8-pin black connector. You will need to dismantle the casing at the steering column (unscrew the fastening screws from the bottom).
2. Next, insert a paperclip and close the two contacts, as in the first photo at the beginning of the article. (these are contacts No. 6 and No. 7).
3. Turn on the ignition and look at the control lamp.
4. The first signal is a long lamp burning - “1”
5. Next, we count the subsequent short signals, if there are 3 short ones then “3”.
6. In our case, the result was code “13”.
