Author: Ivan Baranov

Following the example of foreign automobile companies, it introduces advanced technologies into its vehicles. One such example is an on-board computer, designed to detect a malfunction in the machine using a digital code. We invite you to find out how the on-board computer of the VAZ 2115 is diagnosed - the error codes will also be deciphered in this article.

VDO Panel Errors and Fault Codes

All fuel-injected VAZ 2110, 2111 and 2112 cars have a function such as self-diagnosis of the instrument cluster and even detection of certain errors with codes displayed on the display.
To start this function, you need to hold down the daily mileage reset button and turn on the car's ignition. So that you don’t have to think for a long time about what and how to do, I advise you to watch the detailed video review that I recorded for this topic. The video was made using the example of a VAZ 2112.

As for decoding errors, I will try to make a text description of them below to make it more clear and accessible to everyone.

Video “How to check a Niva Chevrolet car before buying?”

The Two in Niva channel published a video that clearly demonstrated instructions for self-diagnosis of errors.

Few people know that the Chevrolet Niva has a self-diagnosis function that produces basic error codes that can be used to quickly find and fix vehicle problems. It is not difficult to carry out this procedure yourself; just press the odometer button firmly and turn on the ignition at the same time. The arrows on the speedometer will creep up, after pressing again, an information message about the firmware version will be displayed, and the next time, all error codes will appear on the monitor, naturally, if there are malfunctions in the car.

Error codes for the VDO combination on the instrument panel of the VAZ 2110

• If 0 remains, then there are no errors
• When 1 appears, it indicates a microprocessor malfunction
• Open circuit of the fuel level indicator sensor
• Error 4 - increased supply voltage of the on-board network over 16 Volts
• Error 8 - low voltage, less than 8 Volts
• In case of several malfunctions, a number may be issued simultaneously, which will be the sum of the above codes, for example 6 (2+4), 10 (2+8), 12 (4+8) or 14 (2+4+8)

To be honest, these fault codes are not particularly useful. If we compare it with the readings of special on-board computers, such as STAT, then there is, of course, tens of times more useful information and various data. But we’ll talk about this sometime in future articles.

My devices also turn off when you drive and there is some kind of sound, the fuel level also floats, they blow me exactly the same, nothing helped and I looked at the mass on the handbrake, also zero

On my instruments it shows 3456 on top and 78 on the bottom, what does this mean, please tell me

Engine 21124 16 valve

Hello ! Help with the problem, I came to the car yesterday, everything worked, before that I cleaned the injectors. The next day the car started up, but after running for 3-5 seconds it stalled and no more spark, no steering wheel sensor, changed it, then I relieve the pressure in the ramp and try to start it, it starts for 4 seconds and stalls. Where to dig?

Please tell me. I'm getting error 78. VAZ 21124 16v europanel 2007

Hello, my VAZ 10, 8 valves had error 14, I cleared it, do I need to go for diagnostics?

Hello, My VAZ 2110 car will not start. I barely started it with a tugboat, the idle doesn’t work and the throttle doesn’t work, but I need to rev it up, what should I do? Tell me. And error 8 shows how to find this malfunction.

VAZ 2112 16-valve, during self-diagnosis it displays error 818.2... help save what is being done)

Hello, the VAZ 2112 stopped starting, the on-board computer shows error 43210

Who can tell me what error number 8 is?

1 Microprocessor error 2 Fuel gauge sensor circuit error 4 High voltage 8 Low voltage 12 Indicator lamp diagnostic circuit faulty 13 No oxygen sensor/LAMDA probe signal 14 Coolant temperature sensor signal high 15 Coolant temperature sensor signal low 16 On-board voltage too high network 17 Low voltage on-board network 19 Incorrect crankshaft position sensor signal 21 High signal level of the throttle position sensor 22 Low level of the throttle position sensor signal 23 High level of the intake air temperature sensor signal 24 No signal from the vehicle speed sensor 25 Low level of the intake temperature sensor signal air 27 High signal level of the CO potentiometer 28 Low signal level of the CO potentiometer 33 High signal level of the mass air flow sensor For GM NIVA: High signal level of the absolute pressure sensor 34 Low signal level of the mass air flow sensor For GM NIVA: Low signal level of the absolute sensor pressure 35 Idle speed deviation 41 Incorrect phase sensor signal 42 Malfunction of the electronic ignition control circuit 43 Incorrect knock sensor signal 44 Lean mixture 45 Rich mixture 49 Vacuum loss diagnostics 51 EPROM error 52 RAM error 53 No CO potentiometer sensor signal For GM NIVA : increased voltage 54 No signal from the octane corrector sensor 55 Depletion at high engine load For GM NIVA: error in the electronic control unit 61 Degradation of the oxygen sensor/LAMDA probe

Errors persist until they are reset manually! Also mistakes add up! Those. If you have errors 8 and 14, the display will show error 22.

Please help, I stood there warming up for about five minutes, suddenly the car stalled, it started on its own, then, too, at first Troila played with rpms of 1000-1500 and stalled again, and as soon as you press the gas it immediately stalls

The crankshaft sensor or the crankshaft itself may also be the crankshaft gear

Hi, I do everything as in the video, but the diagnostics are not performed, it just switches the mileage to daily and that’s it.

Sergey, press this button on the panel and hold it while turning the ignition key, everything will show there

Did you install a relay on the starter? They have this disease; when the mafon is on or the lighting is on, it does not turn.

Car VAZ 2112 07 1.6 8 cl. After starting the engine when cold, it starts to swarm and check for troubles! I turn it off, start it up again and everything is perfect. Bortovik writes error 4 and 8.

Hello, the error light is on 8 VAZ 2112 1.6 16kl.

Often the CHECK light comes on after 3-4 minutes of operation, and then goes out after 10-15 minutes. I tried to look at the error code - “0” was displayed all the time. There is no noticeable difference in sound and traction. Car - Lada 111, 8 valves, injector. Traveled 60 thousand km. Gasoline A92 at OKKO gas station.

VAZ 2115i 2001, please tell me why, during self-diagnosis from the LCD panel, errors are not displayed for me, this is after all the tests that the system carries out (raising the arrows, indicator lamps, etc.), after which I need to press the reset button again, The version number is displayed and then errors, but there is nothing of this, even though the check light is on. Help someone who knows or has encountered a similar situation. Thank you!

Help me please. VAZ 2112 16 class. It starts normally, doesn’t pull at all, I press the gas more than 1500 and a half thousand. Doesn't pick up speed, starts to stall. The timing belt seems to be all right. I checked the injectors and they are clean. I do not know what to do…

Try looking at the fuel pump or sensors on it.

I had this on a VAZ 2111 model with engines 2112. In general, it picked up speed to 2.5 and began to triple. the problem is in the brain. I flashed my brains and that's it. but they told me my brain might die. but I was lucky.

hi umena es car Citroen C5 2003 garit sweetheart check pazhalusto tell me how zbrosits

Ask yourself for brains so that you can write in Russian.

First, go to school and learn a little)))

Good afternoon. tell. starts well. it works clean in reverse. When I release the throttle (gas) pedal, the engine speed does not immediately drop. and sometimes the idle speed fluctuates

VAZ 2112 temperature warms up to 50-60 degrees and stalls and starts only after 3 hours. The computer shows error 27 and 31, what does this mean, please tell me.

Most likely it is the ignition module. I had this happen, only the temperature rose to 85 and died.

Decoding codes

Now we suggest that you familiarize yourself with the decoding of the combinations. Why errors may occur and how to eliminate them can only be found out as a result of diagnostics.

The elm327 channel published a video showing the diagnostic procedure for a Chevrolet Niva using a special adapter and an Android-based mobile phone.

Common mistakes

First, let's look at deciphering frequently occurring problems that occur in the Chevrolet Aveo in the back of the T250, T300, Niva and other models.

Engine

Let's consider the malfunctions encountered in the operation of power units.

Error 8 on VAZ 2110.8 valves

VAZ error codes 2110

are presented in numerical designation on the screen, and they are transmitted from the phase sensors to the on-board vehicle. This is comfortable, but a novice driver will not be able to understand anything and will not be able to figure out how to use this equipment. But it is necessary to know and be able to do this, because the system, thanks to the integrated self-diagnosis function, will help to identify a malfunction at an early stage, which means it is possible to remove it in time.

You can diagnose the condition of car systems using 2 methods. Let's start with the first one, which does not provide for the introduction of additional equipment.

To start the self-diagnosis function, you need to press the button, which resets the mileage for one day. Turn on the ignition. You will see how the arrows on the devices begin to move from one position to another. This means that the diagnostics of the VAZ 2110 and information has begun to flow from the phase sensors to the ECU. After the process, the RAM will transmit numbers to the display that will show the state of the car’s accounting systems.

VAZ car 2110

When the self-diagnosis is completed and the number 0 is displayed, this means that what remains to be done with the vehicle is in order for our client and all other accounting software systems work as expected:

• if 1 is displayed, this indicates that there are problems with the processor or the RAM is failing;
• 4 — high voltage in the network, more than 16 V;
• if 8, then low.

If there is not one fault, but several, then a figure equal to the sum of the defects will be displayed. If 6 lights up, then this will mean the sum of the numbers 2 and 4. If 14, then most likely there are three malfunctions at once, specifically 4, 4 and 8.

The most common diagnostics that is available to the driver without the use of additional equipment. It will help to identify some faults and also show the condition of the components and allows you to conduct accounting (software) of the VAZ 2110 by and large. However, to specifically identify all defects and decipher information coming from phase sensors, additional tools are needed. For example, the STATE on-board vehicle, which provides more than just data.

Video “Control unit error 1602”

In this video, the author talks about the power failure error on the ECU of a VAZ Priora car.

Error codes - malfunctions of the electric power steering ESD on the Lada Priora VAZ 2170 2171 2172 (Lada Priora)

The first character means the following:

• B – code is intended for body systems, i.e. AIRbags, central locking, electric windows
• C - code is intended for the chassis system, namely the Priora chassis
• P - code is intended for the engine and its operation and / or automatic gearbox (automatic transmission);
• U - code is intended for interaction between electronic units of Lada Priora

Tuning and repair of VAZ 2110

Hello dear visitors of the site vaz2110-remont.ru. The topic of this article will be diagnostics of the tidy on the VAZ 2110, 2111, 2112.

In order to start the self-diagnosis mode of instrument clusters, you must turn on the ignition while holding down the button that resets the daily mileage.

How to understand that the mode has started? Everything is very simple, the oil pressure lights, the battery icon, the fuel warning light and the Chek light will start to light up. In this case, all arrows begin to move from the initial position to the maximum, and this process is repeated. This way you can check the operation of all light bulbs, instruments, and arrows.

Go ahead and press the button to reset the daily mileage. In this case, the arrows return to their initial position, and the firmware version will appear on the on-board computer screen. In our case, this is version 1.1.

When we press the button to reset the daily mileage, an error code will appear.

To reset this error, you need to press and hold the button that resets the daily mileage. Until the error resets to 0.

To check that the errors have been reset, we repeat the procedure: enter the mode - diagnostics of the VAZ 2110 device (while turning on the ignition, press and hold the button that resets the mileage); Press the mileage reset button three times and look at the on-board screen. It should show 0.

We decided on this. But now we need to find out what kind of error we identified during the self-diagnosis of the instrument clusters. A table is presented to you for this purpose.

Enabling and disabling APS-4

The immobilizer, even if it is activated, does not interfere with the operation of any car alarm that you decide to connect additionally. The only thing is that autostart will be impossible with it. It is possible to install a crawler or activate the Valet mode. But in the second case, the engine can be started with a blank, and in the first case, you will need to hack the alarm system.

Shutdown procedure

Of course, here we are looking at how Valet mode is turned on. It will be easy to use:

1. Turn on the ignition without disarming the car;
2. The diode starts blinking;
3. The “red” key fob is brought to the reader, and the ignition is turned off while holding the key fob;
4. The diode will light continuously and the standard alarm buzzer will sound;
5. Remove the key fob;
6. 3-5 seconds after step 3, the diode will start flashing intermittently;
7. Within 10 seconds, install the key fob on the reader again;
8. The standard alarm will produce a sound signal lasting one second, the diode will light continuously;
9. The key fob is removed and the ignition is turned on within 10 seconds;
10. The buzzer emits a short signal and the ignition is turned off.

Errors on the VAZ 2110 on-board computer: note to owners of “Ten”

VAZ 2110 error codes are presented numerically on the display, and they are transmitted from phase sensors to the on-board computer. This is convenient, but a novice driver will not understand much and will not be able to figure out how to use this equipment. But you need to know and be able to do this, since the system, thanks to the built-in self-diagnosis function, will help to identify a malfunction in the early stages, which means it is possible to eliminate it in a timely manner.

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.

Diagnostics

There are two ways to diagnose the condition of car systems. Let's start with the first one, which does not involve the use of additional equipment.

To start the self-diagnosis function, you need to press a button that resets the mileage for the day. Turn on the ignition. You will see how the arrows on the instruments begin to move from one position to another. This means that the diagnostics of the VAZ 2110 has been launched and information has begun to flow from the phase sensors to the ECU. After the process is completed, the RAM will transmit numbers to the display that will show the state of the car’s systems.

Decoding combinations

When the self-diagnosis is completed and the number 0 is displayed, this means that everything is in order with the vehicle and all systems are working as expected:

• if 1 is displayed, this indicates that there are problems with the microprocessor or the RAM is failing;
• 4 — high voltage in the network, more than 16 V;
• if 8, then low.

If there is not one fault, but several, then a figure equal to the sum of faults will be displayed. If 6 lights up, then this will mean the sum of the numbers 2 and 4. If 14, then most likely there are three malfunctions at once, namely 2, 4 and 8.

The simplest diagnostics that is available to the driver without the use of additional equipment. It will, of course, help identify some faults, as well as show the condition of the components and systems of the VAZ 2110 as a whole. But to specifically identify all faults and decipher information coming from phase sensors, additional tools are needed. For example, the on-board computer STATE, which provides more data.

Air and fuel system problem codes

P0030 means that the sensor cable, which is responsible for heating the oxygen, has broken. The break is located before the exhaust gas neutralization system. If the cable of the same sensor is shorted to ground, then code P0031 occurs. If there is a break in the circuit after the neutralizer, the number 6 will appear at the end of the code. Code P0112 is a weak signal from the sensor, which is responsible for the air temperature; if there is a strong signal, then code P0113 appears.

If there are problems with a weak throttle signal, then code P0122 appears, and a strong one - P0123. If there is a problem with the oxygen device, then error P 0130 appears. With P0133, the response to the mixture comes slowly; if error P0134 occurs, the device does not work.

If there is a lot of air in the fuel, then the code is 0171, and if it is 72, there is a lot of gasoline in the mixture. Code P0201-P0204 indicates damage to the injectors and their cables. If there is a code 0217, then the engine is heating up; if it is 0230, there is a malfunction in the fuel pump. With codes from P0261 to P0272, problems need to be looked for in the injectors.

Diagnostics using additional tools

To diagnose cars, including the VAZ 2110, various equipment is used, which is connected to a special connector. Thanks to this equipment, which is not particularly complicated or expensive, you can get a complete picture of the condition of the car.

The service station uses a personal computer to which data from phase sensors is transmitted via a special cable.

Adapter for car diagnostics

Bluetooth devices have appeared on the market that allow diagnostics using a smartphone, tablet or laptop.

They work according to the scheme. The device is connected to the connector, the ignition is turned on and the diagnostic process begins. The data comes from phase sensors to the ECU. From it to a mobile device on which specialized software must first be installed.

This makes it possible not only to obtain more data, but also to present it in a more visual form. This method allows a driver, even with little experience in operating a car (in our case, a VAZ 2110), to obtain all the data about his car.

But most drivers prefer to carry out diagnostics at a service station. So that you are aware of the data that the on-board computer produces through RAM from the phase sensors, we will present the transcripts of common errors.

Comments and reviews

P may also indicate a failure of the system sensor. P This code indicates a malfunction in the immobilizer.

Please note that if error P is not corrected for a long time, the car may simply not start at one point, since the immobilizer will simply block it. We hope the description of these transcripts has been helpful to you. If necessary, you can always ask your question to the specialists of our website.
