What does error 10 mean?
The driver of the VAZ 2114 sees error codes on the dashboard under the speedometer.
In the list of error codes 10 on the VAZ 2114, injector 8 valves do not exist. However, its appearance on the display is not uncommon. It means adding two known codes. To make sure that code 10 is not a glitch that arose as a result of errors stored in the computer’s memory, they can be reset by disconnecting the car’s power supply terminal from the battery. A de-energized control unit will clear the information stored in it. And if, while the car is moving, error 10 in the VAZ 2114 appears again, then you will have to understand its cause.
For reference, we provide a table of codes 1-9, which can also turn out to be independent problems, or consist of codes that are similar in meaning. For example, the number 5 on the display indicates a problem with the temperature controller, and at the same time can be composed of codes 1 and 4.
What to do if the on-board computer on the VAZ-2115 stops working
Sometimes it happens that even though the car is in full working order, the on-board computer completely refuses to work. What to do in this case?
Of course, you can try to fix the problem yourself. But it’s still much better if a real specialist does this. It is he who will be able to reliably determine the cause of the device malfunction.
But before going to the service center, the first thing to do is check fuse F3, which could simply have blown. It is installed in the power supply circuit of the VAZ-2115 processor. If, after replacing the fuse, the on-board computer still shows no signs of life, you can also check the connectors connected to it. We repeat that if you are not an electrician, and generally do not have much knowledge of electronics, this task should be entrusted to a professional.
Remember, any malfunction that the on-board computer shows can be eliminated, just like a breakdown of the on-board computer itself. But, as they say, it is better to prevent a problem than to solve it later. Therefore, each car should be kept in good condition, undergo technical inspection on time and replace spare parts that are out of order. Among other things, it is better not to allow spare parts to break at all, but to replace them as they wear out. Only in this case will driving the car be safe from a technical point of view, and during the trip there will be no emergency situations associated with improper operation of the car.
The serviceability of your car is a guarantee of the safety of both the driver and passengers.
How to fix error 10?
Car service specialists check error 10 with an OBD-2 scanner. Since low voltage in the network is a consequence of weak battery charging, first check its charge level. Every self-respecting car owner is recommended to have a multimeter to monitor the condition of electrical wiring, leads, contact connections and the battery itself. Sometimes VAZ 2114 on-board computers provide erroneous information. This happens because the sensors going from the battery to the computer have “intermediaries” in which the voltage is lost. Therefore, to ensure that the readings are correct, the battery should be measured directly, preferably with a digital multimeter. It is more convenient to use and has less distortion than the traditional one. The voltage in the battery is measured first with the engine running. Normally, the readings should be 13.5-14 V. If it reads 14.2 V or higher, then the battery is discharged and the generator is overloaded to maintain the required voltage. If the multimeter shows a voltage of 13-13.4 V when the engine is running, it means that the battery is not fully charged, and therefore the generator is not working well. The alternator brush may be worn out and require replacement. Pictured: worn generator brushes. New brushes must protrude no less than 5 mm.
If the battery voltage shows less than 11 V when the engine is not running, then the battery is discharged, and before diagnosing the fuel sensor, it must be charged and make sure that the generator is working normally.
It should be taken into account that in cold weather the measuring device may show increased voltage in the vehicle's electrical network for the reason that the battery may have discharged a little overnight due to sub-zero temperatures, or the electronics have reacted to the lower air temperature and are putting more charge into the battery . There is nothing wrong with increased battery voltage. As soon as the electrical consumers turn on, the voltage will equalize.
In addition to the charging state, it is also necessary to inspect the terminals for the presence of oxidation. If necessary, they are cleaned. After making sure the condition of the battery, charging it if necessary, after checking the generator and its brushes, you should again reset all indicators by de-energizing the computer. If the error does not disappear or it changes to number 2, or 0460, you should proceed to checking the fuel level sensor circuit. For this you will also need a multimeter. During the check, it is necessary to inspect the contacts on the FLS itself, ring the wiring coming from it for a short circuit or break. It is also necessary to inspect the sensor itself. It is located next to the submersible fuel pump under the gas tank cap.
And to get to it, you have to remove the rear passenger seat.

Tips and tricks
As you can see, the on-board computer of the VAZ 2115 or VAZ 2114 is connected in the same way as many other devices in the car (for example, a car radio). At the same time, the advantage is that a suitable VAZ 2114 BC or an on-board computer on a VAZ 2115 can be installed in an existing standard place in the car. This means that you can avoid the need to install the device with a separate remote housing.
By the way, if difficulties arise and it is not possible to install an on-board vehicle on a VAZ for one reason or another, a solution can be found on specialized forums or contact an experienced specialist. However, as practice shows, all operations are often standard, that is, special skills and knowledge are not required. The main thing is to carefully study the instructions.
How to Reset the On-Board Computer of a VAZ 2114
Operating instructions for the VAZ-2115 on-board computer
Cars manufactured on the territory of the Russian Federation are equipped with a computer. The first on-board computer appeared on the VAZ-2114. In simple terms, the on-board computer can be considered a kind of electronic reference book on the condition of the car. The driver needs it in order to understand the condition of his car, as well as what faults have appeared in it.
The first on-board computers on domestic cars performed the following functions:
- Controlling the amount of fuel poured into the tank.
- An approximate calculation of the distance that can be driven with the remaining fuel in the tank.
- Monitoring the temperature of the coolant in the engine, as well as preventing it from overheating.
The modern on-board computer on the VAZ-2115 is designed for:
- transmitting information about indicators “online”;
- displaying information on the information panel;
- reflections of route parameters, such as current fuel consumption, travel time, number of kilometers traveled, etc.;
- diagnostics of the engine condition with subsequent display of errors on the on-board computer screen.
Among other things, depending on the vehicle’s configuration, its on-board computer may receive the following data:
- information about the time of the next vehicle maintenance;
- information about the need for adjustments to certain vehicle functions;
- warning about the need to renew the insurance policy;
- information from the organizer;
- parameters at which the cooling system fan will automatically turn on.
Operating principle of the on-board computer
Cars such as the VAZ-2109 were equipped with devices that acted as routers. Let us remember that these were carburetor cars. But the VAZ-2114 and 2115 began to be equipped with injection power plants, which required the use of a completely different type of device.
Therefore, the main functions of the on-board computer on these cars are diagnostics, as well as control of the operation of almost all vehicle systems.
The principle of operation of the on-board computer on the VAZ-2115 is as follows:
- acceptance of signals using the control unit, their subsequent processing and output of the necessary information to the computer display;
- the ability to make some adjustments;
- processing of signals received from systems that are not controlled by the controller. If an abnormal situation occurs in the car, a sound signal will be sent to the on-board computer, and error information will appear on its screen.
Brief instructions for use
The on-board computer in question is a structurally complex electronic design capable of performing about 500 options. The STATE variation is interfaced with the VAZ 2114 ECU, which ensures normal operation of the device. To use the computer correctly, you should study the purpose and functionality of the BC control buttons located on the dashboard.
It is not necessary to keep in mind the decoding of all the codes; you just need to print them out and take them with you. Important notices:
- 2
– excessive voltage in the on-board network; - 3
– problems with the fuel indicator; - 4
– signals a violation of the temperature regime of the power unit; - 6
– indicates engine overheating; - 7
– critical decrease in pressure in the lubrication system; - 8
– violations in the brake unit; - 9
– battery discharge.
It happens that the BC issues codes incorrectly due to the failure of a sensor. However, you should not ignore checking the car, since, most often, the activation of errors indicates a malfunction. After fixing the problem, you should reset the processor. This procedure is performed by turning on and holding the daily mileage button.
