An on-board computer is a device that can increasingly be found not only in foreign, but also in domestic cars. The Lada Granta in the “Norma” and “Lux” trim levels is no exception (owners of a car in the “Standard” trim level can buy it additionally, although the price is quite high). It gives the user many amenities that make driving and monitoring the car’s performance much more comfortable. Today we’ll talk about what the on-board computer is that comes with the Lada Granta, and we’ll look at the errors that the user may encounter.
What device is used on the VAZ 2190
The Lada Granta is equipped with a standard on-board computer, called “State X1 M”, which works thanks to the E-Gas system. The main element of the device is a trip computer with an output to the display. It displays indicators such as:
- Amount of fuel.
- The amount of mileage a car can travel on the remaining fuel.
- Travel time.
- Distance traveled.
- Fuel consumption meter.
Thanks to this, you will know exactly how long you are driving and how critically empty your tank is.
The on-board computer installed in the Lada Granta car is equipped with a diagnostic tester, which contains system diagnostic codes. In addition, thanks to it you can obtain information about the engine temperature and adjust its parameters. It also contains data on the position of the damper, the voltage in the car’s electrical network, as well as a tachometer and speedometer.
Under the hood of the Lada Grant, which is equipped with this device, there are sensors. In case of any violations, all information will be displayed on the on-board computer, which will warn you about them. In particular, you may receive warnings:
- about overheating;
- about problems in the electrical circuit;
- about speeding.
In addition, the device is equipped with a supervisor who is always ready to remind the driver that his lights or turn signals are not turned off. In addition, it will immediately give a signal if the car begins to move forward or backward on its own.
On-board computer firmware Grants
You can update the software yourself. To do this, you will need a USB-K-Line cable, the firmware itself, a diagram of the Lada Granta ECU, an installation program and a driver for connecting to the adapter.
BC connection diagram for firmware
Schema collection algorithm:
- Take 3 wires.
- Switch T1 is closed as required by the program.
- The computer serves as the power source; just connect to Molex. For the on-board device, you can use the terminal block from the cooler.
- Connect the adapter to the USB port and install the driver. Next, you need to remember the port number you are using.
The firmware process looks like this:
- The program starts and the firmware is selected.
- The desired port is selected.
- Click on the lightning icon, after the “Turn on power” message appears, you need to press any button and start the firmware protocol, this will take several minutes.
To download all the software necessary for flashing the firmware, just go to the official website of the manufacturer of the Lada Granta on-board computer. You can also find all the necessary drivers there.
Basic device errors
Setting up such an on-board computer is not something extremely difficult; detailed instructions are always attached to it. If some points are not clear to you, you can always find a video of this process. At the same time, the device can also upset you with an error, despite the fact that there is not always time to look for instructions. Here's an example of a few common device errors you may encounter along the way:
- P0030, 0031, 0032. Errors in the oxygen sensor before the heater. In this case, the on-board computer checks for an open circuit, as well as a possible short circuit to the ground or to the on-board network, respectively;
- P0036, 0037, 0038. In this case, you will be signaled by a sensor located behind the heater. The description of the errors is similar to the previous ones;
- P0112.0113. Intake air temperature sensor signal. In this case, we are talking about too low or high signal, respectively;
- P0116, 0117, 0118. Alert from the coolant temperature sensor. The code signals either that the signal is out of range, or that the readings are too low or too high;
- P0122, 0123. In this case, throttle valve sensor No. 1 signals you, notifying you that the signal level is too high or low.
Setting up and unlocking
You can unlock the onboard vehicle using the same firmware. Setting up the device is a simple task if you follow the instructions included with the device. You can also find out the answer to your question on the manufacturer’s official website or watch training videos.
Using the instructions, you can not only quickly set up the device, but also find out the codes of all possible errors. This will help to diagnose the malfunction in time and take measures to eliminate it.
In comparison with the standard BC on the Granta dashboard, any other on-board vehicle will be distinguished by its expanded functionality. You can do without them, but in this case, if you need to diagnose the car, you will have to contact a service center. By installing an on-board computer, the owner of the Grant can independently monitor all engine operation processes, diagnose malfunctions and activate some parameters.
The question of purchasing an additional on-board computer for the Lada Granta is asked by a category of owners who are not satisfied with the low information content of the standard dashboard. Armed with the goal of acquiring this device, you should carefully select the appropriate controller for a specific modification of the VAZ model. The market is not replete with goods of this type, but you should work hard to choose the right one and install the trip computer into the panel of the Lada Granta yourself. The instructions will help you with this.
Functionality on board the vehicle
All existing models of on-board aircraft are quite informatively equipped. This advantage is beneficial for people with poor vision and especially for women who do not understand the operation of engine systems.
The router can easily point to parameters such as:
- Fuel consumption in various driving modes;
- Average speed and amount of fuel consumed during the entire trip;
- Travel time;
- Engine temperature both before and after warming up;
- Temperature outside and inside the car;
- Malfunctions of various vehicle systems;
- Warm up and dry spark plugs when required.
By the way, if the device cannot decipher errors in engine operation, but only shows its number, then the malfunction can be diagnosed using a list of codes.
In addition to the above, the computer has non-volatile memory and an indicator that the headlights or turn signals are on.
Basic functions of the device
On-board vehicles 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
The STATE model provides for installation of the router directly on the instrument panel, which prevents the warranty of a new car from being violated in the event of damage to the trim. Installation is carried out by removing the plug under the button, then installing a device with connected wiring in the free space. The other end of the wire is connected to the diagnostic connector. This device also has a built-in tester that allows you to monitor the condition of the electrical circuit, which helps to anticipate a possible short circuit in the wiring.
Installing the device into a standard connector
Low cost, ease of operation, and compactness are quite convincing arguments for purchasing the STAT X1 device for your car. This will make using the car convenient and safe.
Options for installing BC in Lada Granta
Any of the existing onboard devices can be installed and connected independently, regardless of the modification of the car. The exception is computer models in the “Lux” configuration - they are initially installed at the factory with a multimedia system, navigator, and audio system. The “State” X1 M device can be added to the “Standard” and “Norma” configurations.
An important advantage of the “State” X1 M is its compact size. The device is installed instead of a button cover. The kit includes the device, wires and instructions. Installation will not cause much difficulty. You need to take out the plug, place the computer in it, connecting it to the connector. Then, in accordance with the pinout, connect the second end of the wiring with the block to the diagnostic connector located on the bottom left side of the panel. In addition to the State X1 M, Multitronics are often installed on Lada Granta. You can attach it wherever it is convenient for the driver - on the dashboard, on the rearview mirror. The main difficulty is connecting the wiring, since it needs to be hidden. If you install the device on a panel, you will first have to remove its front side and make a hole for the wires, for example, using a heated knife. Then the BC visor is glued to “liquid nails” type glue.
Versatile alternative
You can install other models of devices on the Lada VAZ 2190 car. A good alternative in this regard would be the Multitronics router. Various types of device housing allow it to be installed in any place convenient for the driver. However, when mounting grants into the dashboard, it may be difficult to pull the wiring to the diagnostic block. The panel will need to be removed and holes drilled, which may void the machine's warranty. If the device cannot determine the specified settings, it will need to be reflashed, and this can already be attributed to the disadvantages of the model.
Multitronix has a very convenient user interface and simple settings, as well as clarity and speed in operation. Naturally, under the supervision of such an “assistant” the car will always be under vigilant control. Its price will be higher than that of the STAT on-board vehicle, which is more adapted to the Grant.
Since the release of the Lada VAZ 2190 for sale began at the end of 2011, it was quite difficult to initially purchase some electronic components for this car. This circumstance slightly slowed down the growth of the popularity of this car. However, today you can buy a router for a VAZ 2190 from almost any supplier of automotive products.
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.
How to install the device?
By purchasing the “State” controller model, the owner becomes able to install the device independently after purchasing the Lada Granta; detailed instructions will help with this. This eliminates concerns about loss of warranty service, since the Lada Granta panel is already equipped with the appropriate connector from the factory. After installing the controller, the entire list of electrical devices integrated into the panel is not damaged.
Installation is carried out after removing the factory plug in the designated place on the panel. This device with the attached wiring is installed inside the niche that appears. The end part of the controller cable is brought out to the location of the diagnostic block and connected to its connector. The diagnostic socket is located in the lower part near the passenger seat.
The on-board computer has gained popularity due to the presence of such important and balanced consumer qualities as:
- relatively low price;
- compact dimensions;
- ease and accessibility of installation for the vast majority of Grant owners.
Having decided to purchase this particular model, the owner of the Lada Granta ensures comfortable and safe operation of his “iron horse”.
Video instructions about the operating features of this controller will allow you to study this device in sufficient detail. But more than one “State” can be equipped with a LADA Granta panel. Among alternative products, you should consider the Multitronics model. Various versions of this device are endowed with versatility due to the possibility of their installation in the places of the car’s interior that the owner likes (windshield, panel, etc.).
Installing this option in the Din socket of the panel causes some difficulties due to the need for careful routing of the wiring to the place where the diagnostic block “habits”. For these purposes, it will be necessary to dismantle the dashboard to make technological holes for the wiring “route”. It is recommended to resort to these manipulations using a heated knife, which will avoid noticeable deformations of the panel. The wiring should be firmly fixed to the inner surface of the panel in order to prevent the noise it creates when moving. The case itself, which has a standard computer, is best attached to the panel using liquid nails.
After connecting the router cables to the diagnostic block connector, the device must be adapted to the network, which implies determining a complete list of on-board settings. If this process is not observed for some time, the firmware version should be changed in order to provide it with the ability to support protocols in the “CAN” format.
