Error checking VAZ 2110 8 valves injector self-diagnosis

Decoding VAZ 2110 error codes and measures to eliminate them

Many VAZ 2110 car owners, especially those who have no accumulated experience in driving and repairing the “tens”, fall into a slight panic if “CHECK” suddenly lights up on a seemingly serviceable car, and the on-board computer begins to generate an error.
They are usually expressed using the letter P and a numeric four-digit code. Naturally, error codes for the VAZ 2110 are not difficult to find in special tables in order to understand in which system the cause should be looked for. However, the decoding is often very vague, and it is not clear what to do next?

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.

Electronics

Let's look at some especially annoying error codes, which, as if they don’t affect the speed, but constantly remind you that something may be wrong with the VAZ 2110. These include:

• error 1621, warning the driver that the RAM is disabled, that is, code 1621 indicates that the controller is not working, which means that errors are not read, you remain in the dark about what is happening with the systems of your car. Most often, when drivers see the numbers 1621, they ignore them, reset the RAM error (remove the terminal from the battery for a couple of minutes, then put it back on) and drive on. But, after turning off the car and starting it again, they see the same ill-fated code 1621. You can try to carefully inspect the twist near the ECU (to ground), and perhaps additionally solder the factory crimp. However, often even contacting specialists does not help; code 1621 remains on until the RAM memory is changed;
• Sometimes it happens that the injector light comes on. This is especially observed in winter, and when the engine warms up well, the light goes out. Although this is not so scary, it is somewhat unnerving, and the light bulb breaks down if it burns for a long time. It’s better to contact a service center where they can update the firmware, then the light bulb will stop bothering you.

Ideas for tuning and modifying the shield

How can you improve the tidy in the “Ten”:

1. By installing a new trim on the console. This type of tuning is the simplest, since you just need to install a trim on top. However, it will not improve the dashboard itself in any way, only its upper part.
2. In the VAZ 2110 you can install a dashboard from Priora; in general, the selection of tuned, ready-to-use dashboards is quite large. When installing a device in 2110 from another car, you will have to partially redo some connectors and connect new devices. But in general there is nothing difficult about this.
3. Installation of new scales on sensors. Scales can be downloaded from the Internet, found in a store, or developed independently. The alteration procedure in this case will be more complicated - you will have to remove the shield and disconnect the arrows from the instruments, this will take time. After installing the new scales, the arrows must be correctly installed, otherwise the speedometer and other sensors may malfunction.
4. Installation of LED lighting in the tidy. You can simply replace standard light bulbs with LED ones, or purchase a diode strip and solder it into the shield. But keep in mind that if the light bulb fails, it can be replaced without any problems, which cannot be said about the LED strip. If it burns out, you will have to unsolder the tape and install a new one in its place. Although the service life of the LED strip is quite long.
5. If you install diode lamps, then you can additionally paint the numbers on the scales, as well as the arrows of the sensors, with fluorescent paint. The fact is that combining these two types of tuning will allow you to achieve a truly high-quality and beautiful result. Under LED lighting, arrows painted with luminescent paint will glow much brighter.

Crankshaft and camshaft

• code 0335 indicates a malfunction of the crankshaft position sensor. Therefore, when you see 0335 on the computer, you need to check whether the signal is coming from this sensor. If you find that the signal is weak, you can help by changing the air flow if it is excessive (above the maximum). After this, error 0335 should disappear;
• When you see error 0340, you know that the camshaft position sensor is most likely faulty. Although in fact, even if 0340 is displayed, the camshaft itself may be in good condition, the car is working as usual. But when the numbers 0340 do not disappear while the engine is running, this unit should be carefully inspected.

You can read more about the operation of the crankshaft sensor in this material: https://vazweb.ru/desyatka/dvigatel/datchik-kolenvala.html

Electrical equipment

Malfunctions of the electrical equipment of the VAZ 2110 should be responded to as quickly as possible. By the way, this can be signaled by code 1602, although its decoding sounds like a loss of on-board power supply voltage in the RAM.

Sometimes it is enough to reset error 1602, and it will not appear again. Some people call these numbers “good”; 1602 may appear after the battery is disconnected, due to a voltage surge when starting the engine (for example, in cold weather). However, if 1602 “pops up” constantly, you need to look for a network break.

First, try to clean the battery terminals and secure them well. Did not help? Check the circuit, starting from the “+” of the battery, be sure to check the fuse, fuse link.

Oxidized battery terminals

And also inspect the mass of the ECU, TPS. There are cases when code 1602 appears due to the fact that the security alarm blocks the controller circuit, and it issues this as an error every time. You should contact the installer of your alarm system.

How to reset the error?

You can delete the error code from the memory of the VAZ control unit by disconnecting the terminal from the battery.

The reset procedure is performed as follows:

1. The vehicle's ignition system is activated, but the power unit does not start.
2. The engine compartment of the vehicle opens. Using a wrench, loosen the screw that secures the terminal clamp on the negative output of the battery.
3. After about one minute the contact is reconnected.
4. The engine compartment of the car is closed, the ignition system in the car is turned off.
5. The car engine is starting. If the “Check” indicator remains lit on the dashboard, it should disappear on its own after a few kilometers.

Idling

Code 0505 indicates a malfunction of the idle air control. Moreover, 0505 is most often “issued” when the engine is started with the gas pedal pressed. This often affects drivers who switched from a carburetor VAZ 2110 to an injection one.

However, 0505 also occurs if the ignition module, spark plugs are faulty, there are broken wires, or the engine speed is not the one set by the XX regulator.

Idle speed control

If you notice popping noises in the muffler, this may also indicate displacement of the crankshaft ring gear. Code 0505 can be displayed either alone or with 0300 (missing cylinders).

Other problems

Carrying out vehicle diagnostics makes it possible to decipher fault codes in the control relays of various components, road terrain sensors, fuel mixture saturation and some other indicators. The designations are numbered as follows after “P”:

• 0500, 0501, 0506, 0511 – problems with the speed and idle speed sensor;
• 0560, 0562, 0563 – differences in on-board network voltage;
• 0615, 0616, 0617 – problems with the additional starter relay;
• 0627, 0628, 0629 – signal about a malfunction of the fuel pump relay;
• 0645, 0646, 0647 – displays problems with the compressor clutch;
• 0685, 0686, 0687 – short circuit to the main relay circuit;
• 0691, 0692 – fan element malfunction;
• 1123, 1124, 1127, 1128 – substandard mixture in idle mode;
• 1301, 1302, 1303, 1304 – critical misfire in the cylinders;
• 1410, 1425, 1426 – problems in the absorber purge valve circuit;
• 1513, 1514 – open circuit in the idle speed regulator circuit;
• 1602, 1606, 1616, 1617 – violation of the rough road sensor readings;
• 2301, 2303, 2305, 2307 – short circuit to the cylinder ignition coils.

Throttle valve

The on-board computer issues two unpleasant errors - 0122 and 0123 when there is a problem with the throttle sensor. Moreover, 0122 will be displayed if the signal level of this sensor is low, and 0123 – if it is high.

Both one and the other, naturally, are not good. Especially if the on-board computer readings are accompanied by increased idle speeds, jerks at low speeds and dips. In this case, replacing the sensor does not always help.

Throttle position sensor

If codes 0122, 0123 are issued, be sure to check the signal and power wires for breaks, and also pay attention to whether there is any leakage through the injector rings. Remember: the main enemies of DPZD are engine washing and also the manufacturing plant, since there are a lot of defects here.

The following material is devoted to common malfunctions of the throttle position sensor: https://vazweb.ru/desyatka/pitanie/drosselnaya-zaslonka.html

Oxygen sensor

For some reason, it is quite difficult to find code 0525 in the decoding tables, but this is simply an error in the oxygen sensor, otherwise called a lambda probe. And if you see 0525 on the display again, it means that not everything is in order with the oxygen content in the exhaust.

This sensor is not installed on all VAZ models; it sends a signal to the engine regarding how much oxygen should be in the fuel system. That this sensor does not cope with its duties is evidenced by:

• increased fuel consumption;
• unstable work at XX;
• loss of power, lack of "response".

Lambda probe of the new Bosch model
In principle, the lambda probe should be changed after approximately 60 thousand mileage, but this can happen earlier, especially considering the quality of our gasoline. Therefore, it may display 0525, warning that it is time to replace the oxygen sensor.

Additional panel

The additional front panel of the new-style BSK control has indicators:

• An oil can is shown. If the light works, check the oil level;
• An icon lights up, which, with some imagination, can be “identified” as working wipers. This indicates that there is not enough windshield washer fluid in the tank;
• Conventional image of a thermometer over a container with liquid - high temperature of antifreeze;
• A crossed out light, which the arrow points to, is a sign that the brake light or parking lights are not working;
• If the light with the image of a wheel with brake pads lights up, it is quite possible that the pads are worn out and require replacement;
• The sign of a man with a seat belt indicates that the seat belt should be fastened.

Error Diagnosis Methods

In 2022, errors on the VAZ 2110 on-board computer can be identified in two ways.

1. Self-diagnosis. The method is feasible thanks to a special option in the on-board computer. The principle is that the system shows faults in the main circuits and mechanisms. The advantage is that there is no need for additional equipment or special programs - everything that is needed is already “hardwired” into the on-board computer. The disadvantages include the low accuracy of the readings.
2. With the help of auxiliary equipment. This type of procedure is characterized by high accuracy of the read data. Thanks to a third-party analyzer, you can find out exactly where the breakdown occurred, which simplifies the repair process. An obvious disadvantage is the need to connect a computer with a special program. Such equipment is present only in specialized service stations.

Self-diagnosis VAZ 2110: error codes

To enable self-diagnosis mode, the driver or technician will need to perform a certain sequence of actions.

1. Turn off the engine ignition.
2. Press the daily mileage reset button and, without releasing it, turn on the ignition. In this case, all digital cells should light up on the display.
3. Click on any module control button twice.
4. The device will display the error number.

If everything is done correctly, one of the following symbols will light up on the device:

• 2 – critical excess of the rated voltage of the on-board network, a short circuit of the main line or loaded components is possible;
• 3 – a similar error on the instrument panel of the VAZ 2110 indicates that the gasoline level sensor is damaged or there are problems in the sensor’s power supply; to check, you can replace the part with a new one and ring the circuit;
• 4 - error 4 VAZ 2110 indicates that the antifreeze temperature sensor is broken or its wiring is broken, the problem is resolved in the same way;
• 5 – the thermometer designed to measure the temperature outside is faulty;
• 6 – the engine is very overheated, you need to stop and wait for it to cool down, and there should be a sound signal (add antifreeze/water into the radiator);
• 7 – the lubricant pressure in the crankcase compartment of the engine is below the established norm, the losses must be urgently replenished;
• 8 – error 8 VAZ 2110, interpretation shows that the brake system is damaged, possibly a drop in the fluid level in the expansion tank or severe wear of the pads;
• 9 – the battery is completely discharged, the element needs to be charged or replaced with a new module;
• E – software failure of the on-board computer firmware; complete diagnostics with a scanner and qualified repairs in a workshop will help here.

Also, error 14 VAZ 2110 or another two-digit number will indicate the presence of two problems. Usually, with such a picture, the ciphers are summed up. For example, error 10 VAZ 2110 may indicate problems in circuits No. 4 and 6.

How to reset errors on a VAZ 2110

Typically, the procedure is carried out after repairing the unit for which the fault code is responsible. In this case, the symbol does not disappear - it must be forcibly reset. This is done quite simply. The user is required to enter the service mode (hold down the daily mileage button), then double-click on any control. After completing the manipulations, a code will appear on the display. To eliminate this, the daily mileage button is pressed for 3-4 seconds and the system is reset. The machine exits the dialog box automatically after 30 seconds of inactivity.

Description and location of indicators and instruments on the panel

Let's start with a description and designation of the instrument panel icons and symbols in 21102:

1. Engine coolant temperature controller; this sensor determines the temperature of the engine as a whole. Thanks to the device, it is possible to promptly detect overheating of the power unit.
2. Tachometer. This controller is designed to display crankshaft speed readings.
3. The left turn signal indicator always flashes when the turn is turned on.
4. Left right turn signal. Icons numbered 3 and 4 blink synchronously when the light alarm is turned on.
5. Speedometer. Thanks to the speedometer, the driver can know how fast his car is moving.
6. A controller for the volume of remaining fuel in the tank, which helps the driver navigate when to refuel. If there are about 5-7 liters of fuel left in the tank, a yellow indicator in the form of a gas pump will light up next to the sensor. Do not operate a car with a yellow light on regularly, as this can lead to failure of the fuel pump.
7. The gas station indicator, which we described above.
8. Light symbol for turning on the side lights.
9. The brake system performance symbol appears on the instrument panel when the engine is running if there is not enough brake fluid in the expansion tank. The problem may be due to a leak.
10. High beam activation icon.
11. Clock setting regulator with switch. Can be used to switch between daily and total mileage data.
12. At the bottom of the instrument cluster there is a small screen that displays data on the vehicle's kilometers traveled.
13. A light bulb that lights up when the light alarm is activated.
14. Check Engine symbol. Its appearance indicates that the control unit has detected a problem with the motor. It is advisable to turn off the power unit and identify the breakdown, which is often caused by the inoperability of auxiliary sensors.
15. Clock screen. When the regulator is switched, it may display data on the outside air temperature if such a sensor is installed.
16. This instrument lamp indicates a detected malfunction in the battery charging system. The cause may be a loose, worn or broken generator set drive belt. It may also indicate a malfunction of the unit itself, damage to the power circuit and other problems in its operation.
17. Handbrake activation icon.
18. The symbol in the form of an oil can indicates an insufficient level of engine fluid pressure in the internal combustion engine. When it appears, you need to turn off the car engine and find the cause, which is usually an oil leak from the system.
19. The air damper icon is placed only on carburetor engines (the author of the video is the In the Garage channel).

Features of the old and new dashboard

Over the decades of production of the VAZ 2110, the dashboard has undergone certain changes. Therefore, devices can be divided into two groups - devices of the old and new models. It should be noted that these dashboards are not interchangeable, since they have different electrical connection diagrams, as well as designs of the central console in the cars. Moreover, both types of devices are characterized by different shapes, but as for the location of sensors and indicators, in fact it is almost the same.

Over time, devices began to be equipped with backlight brightness controls. In addition, digital odometers (mileage meters) were not used on old-style dashboards; they began to be installed much later. At first, the odometer was mechanical (author - proVAZ-2110 channel).

Diagnostics using a scanner

The method involves connecting an external computer with the program installed. This opens up more opportunities for car diagnostics. In this case, error codes for VAZ 2110 and VAZ 2112 consist of 5 characters.

• P – failure or malfunction of the power plant, transmission;
• B – body systems are damaged;
• C – a problem has been detected in the vehicle’s chassis;
• U – violation of pairing of different modules.

• 0 – general value;
• 1/2 – manufacturer code;
• 3 – reserve.

• 1-2 – violation in the air-fuel mixture supply devices;
• 3 – malfunction of the ignition units;
• 4 – atmospheric emissions control device;
• 5 – malfunction of the engine speed or engine speed meters;
• 6 – failures in electronics;
• 7-8 – malfunction of the gearbox module;
• 9-0 – reserve unit.

The last two digits give the serial number of the breakdown and its location.

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.

VAZ 2110 car

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.

Possible mistakes

VAZ 2110 injector error

Errors can relate to various parts of the car:

• ​ Sensors. Temperature sensors are most often affected.
• ​ Injectors (see VAZ 2110 injectors and their cleaning). Mostly, problems are observed due to an open circuit, as a result of which the injectors cannot light up in time.
• ​ Engine. Engine problems usually appear after driving a car for a long time. The most common mistake is overheating.
• Valves.
• ​ Fans. If they do not work with all their strength, the machine overheats. Therefore, errors of incorrect fan operation lead to errors with engine overheating.
• ​ Relay.
• ​ Controller.

Decoding codes

Let's look at the most common VAZ 2110 injector error codes that the system produces:

• ​ P0101. In this case, there is a problem with the air sensor. When such a code appears on the on-board computer screen, you should check whether the sensor is really damaged.

Note: during the test, air must not be consumed more than the permissible norm.

• ​ P0113. This means that the intake air temperature sensor is faulty. It is important to check whether the temperature exceeds the norm.
• ​ P0116. If this code appears on the ECU screen, then there is a problem with the antifreeze temperature control sensor. First of all, you need to check whether the sensor is actually working poorly, and only after that take the car to a car service center.

Note: if the temperature is below the required value, then this defect must be eliminated urgently, otherwise it can lead to harmful consequences.

• ​ P2135. In this case, the error indicates an incorrect throttle position. The signal between the sensors may have weakened, so they cannot correctly indicate its location. If after diagnostics it is discovered that the voltage of one sensor is higher by a threshold compared to the other, then repair cannot be avoided.
• ​ P2122. One of the accelerator pedal sensors shows too low values. At the same time, it also exhibits extremely low voltage. You need to check the voltage in the sensor using a voltmeter. If necessary, replace the faulty sensor.
• ​ P0201. In this case, there may be a break in the injector control circuit. It is necessary to diagnose the drivers, as it is possible that the error is generated due to them.
• ​ P0130. It is necessary to check whether the signal circuit is intact.

Note: some action must be taken if the voltage in the circuit is lower or higher than normal.

• ​ P0133. If for some reason the signal lasts longer than necessary, the on-board computer will display this exact error. The cause of this malfunction is the response from the alarm system is too slow.
• ​ P0030. You need to check if there is an open circuit in the heater circuit. If necessary, perform driver diagnostics.
• ​ P0171. Perhaps the heating mixture has become too lean. Therefore, the driver must check whether its contents are too lean. If the heat transfer is higher than normal, then this needs to be corrected and the defects eliminated.
• ​ P0172. It is necessary to check the leanness of the mixture.
• ​ P0217. The engine has overheated. It is necessary to monitor the increase in temperature in it.

Note: if the temperature here is above the threshold value, then repairs are urgently needed, otherwise the engine may soon boil right on the road.

• ​ P0300. When ignited, toxic gases may be released. In fact, they are always emitted, but they are successfully removed through the exhaust pipe. Moreover, if for some reason there are gaps in the system, then toxic substances can get directly into the car’s interior.
• ​ P0326. The knock sensor may not always work. You should check whether its signal level is too low. If necessary, regulate and normalize this level.
• ​ P0335. The crankshaft position sensor is faulty. You need to check if there is a signal coming from the sensor. If the signal is low, the air flow should be changed if it is above the maximum value.
• ​ P0340. The camshaft position sensor is faulty. You should check if there is a signal.

Note: Problems generally occur when the sensor signal does not change while the engine is running.

• ​ Z0351. There may be a break in the circuit. In the primary circuit, the current does not reach the optimal level.

Prevention of breakdowns of electrical appliances

To prevent breakdowns of electrical circuits, you must follow a number of simple rules.

1. Periodically check the contact connectors for oxidation or overheating. Rust disrupts the passage of impulses, which can be read by instruments as damage to the unit.
2. Once a year, treat contacts with special oils. Lubricants prevent moisture from entering metals, which prolongs their service life.
3. Replace dry wires in a timely manner. Cracked insulation can cause a short circuit.

Errors on the VAZ 2110 (2112) panel provide the user with complete information about the condition of the vehicle’s components and assemblies. If you know the decryptions, the driver can independently fix the breakdown of the vehicle electronics.

Car diagnostics

The appearance of a lit “Check Engine” lamp on the instrument cluster signals the driver that a problem has arisen in the vehicle’s electrical system. You need to understand that checking the vehicle yourself and at a service station can give different results. Special equipment available to professionals will allow more accurate detection of faults.

Self-diagnosis

On a VAZ 2115, the owner can do independent diagnostics and find out what errors are stored in the memory of the engine control unit. The procedure is carried out by calling up fault codes on the dashboard or using a diagnostic adapter.

To carry out diagnostics on the electronic instrument panel, you must perform a certain sequence of actions:

1. Sit in the driver's seat of the car, insert the key into the ignition and press the daily mileage reset button located on the instrument cluster.
2. Turn the lock key to the ignition switch position.
3. Release the key, starting the self-diagnosis process. Visually, this will look like turning on the backlight, all signal lamps, possible symbols on the LCD screens and testing the instruments (the arrows will move across the entire scale in both directions).
4. Press the key again and release. The second press displays the software version of the instrument cluster on the screen located under the speedometer (inscription like Uer x. x).
5. Press the key again, after which the errors in the memory will be displayed on the screen.

Instrument cluster VAZ 2115, the button is located on the right side of the speedometer

The driver can perform self-diagnosis on the electromechanical panel and the “January-4” control unit according to the following sequence:

1. Turn off the ignition.
2. Open the diagnostic connector cover located on the center console.
3. Connect contact B to the negative terminal of the battery (to the body). Contact A, connected to the engine crankcase, is suitable for this.
4. Turn on the ignition. The “Check Engine” lamp will flash code 12, which means the diagnosis has begun. The light signals are given as follows - a long flash, then a pause (about 2 seconds), two short flashes, a long pause (about 3 seconds). Signal 12 is sent three times. If there is no signal, the diagnostic system is inactive or faulty. After this, the Check Engine light will flash and list the errors in memory. Each code is repeated three times. If there are no errors in the memory, code 12 will continue to be transmitted.

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.

Description of the VAZ 2110 dashboard buttons

Well, let’s immediately move on to the description of the buttons on the dashboard of the VAZ 2110.

Instrument panel of a VAZ 2110 car - the buttons located on it are marked on the arrows

As you can see from the screenshot, there are only 4 buttons on the instrument panel of the VAZ 2110 - let's move on to their description.

1. Button to turn on/off the front fog lights.
2. Turn on/off outdoor lighting.
3. Heated rear window
4. Button for turning on/off the rear fog lights.

In addition to the buttons located on the dashboard, there are others that are located under the stove, next to the radio in the cabin. Let's find out their functions:

Instrument panel VAZ 2110 - description of the buttons next to the stove

Many VAZ 2110 owners wonder why these 4 buttons, which are located on the dashboard under the stove, are needed. The answer will seem rather banal to you:

These buttons actually do not play any function; I think the engineers working on the ten wanted to add electric windows to the car, but for some reason they forgot to do this.

Okay, it was a joke! In fact, these buttons are responsible for the following:

1. Turning recirculation on/off
2. Button for installing additional equipment (for example, power windows)
3. Turning the hazard warning lights on/off
4. Button for installing additional equipment (for example, power windows)

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

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

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.

What does Code P0102 mean?

This diagnostic trouble code (DTC) is a generic transmission code, which means it applies to OBD-II equipped vehicles equipped with a mass air flow sensor. Including vehicles such as Toyota, Infiniti, Nissan, Jaguar, Audi, Mercedes, Dodge, Hyundai, Chevy, Ford, etc. General repair steps may vary depending on the make/model.

The mass air flow sensor is installed in the engine air intake downstream of the air filter, and is used to measure the volume and density of air drawn into the engine.

The air flow sensor itself only measures a portion of the incoming air, and this value is used to calculate the total volume and density of the incoming air.

The ECU uses these readings along with other sensor parameters to ensure the correct fuel is being delivered at all times for optimal power and fuel efficiency.

DTC P0102 indicates that a low input signal has been detected in the sensor or circuit. The control unit sees that the actual MAF frequency signal is not within the normal expected range of the calculated value and causes an error.

Some mass air flow sensors also contain a temperature sensor, which is also used by the ECU for optimal engine operation.

What does error 8 mean on the VAZ-2114 instrument panel and how to fix it

The VAZ-2114 is based on mechanics, so for many drivers it comes as a real surprise that the car has self-diagnosis.
This allows you to avoid checking the operation of the machine at a service station using expensive equipment; the fault can be determined with your own hands at any convenient time, and then quickly eliminated. Diagnostics of the VAZ-2114 involves displaying an error code on the on-board screen, which indicates a specific breakdown. Error 8, displayed on the panel, stands for insufficient voltage in the machine network. We will tell you how to fix the problem, but first we will teach you how to enable self-diagnosis of the VAZ-2114.

How to diagnose the error?

There are two options for diagnosing a VAZ car - testing using the instrument panel and using a computer. The second option is considered more accurate, but its implementation will require a special program and a cable for connecting to the diagnostic connector.

Checking using a computer is done like this:

1. The diagnostic wire is connected to the laptop. Its second end must be connected to the OBD2 connector in the Lada car. The location of this block differs depending on the car model; this nuance must be clarified in the service manual.
2. A diagnostic program is launched on the computer, which allows you to decipher error codes. To start the test, press the corresponding button.
3. The diagnostic process begins. Depending on the utility, the program can separately check the operation of the engine, transmission or electronics.
4. After the test is completed, combinations of faults will appear on the computer screen that need to be deciphered. Depending on the program, a description of the error may also be displayed immediately.

Instructions for self-diagnosis of VAZ-2114

To enable self-diagnosis in a domestic car, take the driver’s seat and sequentially perform the following manipulations:

1. Find the odometer key on the instrument panel, press and do not release.
2. At this time, turn the key in the ignition, setting format 1.
3. The odometer key can now be released.
4. Observe what changes occur on the instrument panel, namely the arrows should jump.
5. Press the odometer key again and release it again, after which numbers indicating the firmware of the vehicle’s on-board computer are visible on the speedometer.
6. All that remains is to press the odometer key a third time, and then remove your hand, and the display of a combination of faults on the screen will not take long. Please note that at a service station the error consists of 4 digits; if you diagnose it yourself, it assumes 2 digits.

SELF-DIAGNOSTICS OF THE KALINA/PRIORA INSTRUMENT COMBINATION

1. With the ignition off, press the “Reset” button (reset daily mileage). While holding the button, turn on the ignition.
2. The instrument panel will go into self-diagnosis mode, all segment positions will light up on the display, all indicators will light up, and the arrows will travel the full path.
3. Using the control button on the right steering column switch, we switch between modes (self-diagnosis, firmware version, error codes).
4. To reset errors, you need to be in error mode and press and hold the “Reset” button for more than 3s.
5. The diagnostic mode exits automatically after inactivity for 20-30 seconds.

Decoding error codes in the dashboard:

• 2-increased voltage of the on-board network;
• 3-fuel level sensor error (if a break in the sensor circuit is detected within 20s);
• 4-error of the coolant temperature sensor (if an open circuit of the sensor is detected within 20s);
• 5-outside temperature sensor error (if there are no sensor readings within 20s, indication on the LCD is “-C”);
• 6-engine overheating (the criterion for triggering the acoustic alarm has been met);
• 7-emergency oil pressure (the criterion for triggering the acoustic alarm is met);
• 8-defect of the brake system (the criterion for triggering the acoustic alarm is met);
• The 9-battery is discharged (the criterion for triggering the acoustic alarm is met);
• E-determination of an error in a data packet stored in EEPROM.

What does error 8 mean and how to fix it

Error 8, reflected on the on-board computer of the VAZ-2114, means low voltage on the on-board network. Reasons that can cause a decrease in voltage in the VAZ-2114:

• the battery is almost completely discharged;
• erasing or “freezing”, lack of adequate operation of the brushes on the generator.

That is, you can remove error 8 and correct problems in the operation of the VAZ-2114 by charging the car battery or replacing the brushes on the generator, and all this can be done without turning to specialists, in your own garage with your own hands.

Reasons for error 8

Knowing what error number 8 on the instrument panel means, it is easy to determine the reasons for its occurrence. There are only two main reasons. This is a discharged or faulty battery or a failed generator.

For the latter, this most often indicates the need to replace the brushes, since the old ones are already worn out. In addition, the code may occur in such cases as:

• Poor contact at the battery terminals or generator contacts;
• Damage to battery or generator wires.

Sometimes an error indicates other problems. But this happens very rarely.

You can determine the exact reason for this behavior of the car on your own. First, you should visually inspect the battery and generator and their contacts. You may notice oxides and other defects on the terminals and connectors. There is often visible damage to the wiring. The battery terminals may not be properly tightened. In rare cases, you may notice that the battery is swollen.

It is useful to check what the voltage is in the on-board network on the dashboard. You need to pay attention at what point it decreases or constantly remains low. You should also diagnose the battery and generator with a multimeter in voltmeter mode.

Battery diagnostics is performed as follows:

• Set the measuring device to voltmeter mode. Select a voltage of about 20 Volts;
• Connect the black probe to the negative terminal of the battery, and the red one to the positive terminal.
• Evaluate the device readings. If the battery is charged, the display should show at least 12 volts.

If the value is lower, then the battery needs to be charged. If after this, it does not charge completely or discharges quickly, it should be tested with a load fork. This can be done independently or at a car service center.

You should also check the operation of the generator. To do this you need:

• Take a multimeter and set it to voltmeter mode, set the voltage to approximately 20 Volts;
• Connect the black probe to the negative of the battery, and the red one to the positive;
• Start the power unit and wait until the speed stabilizes;
• Evaluate the value on the device display. During normal operation of the generator, it should be at least 13.5 Volts. If the multimeter shows a figure less than the specified one, the generator is not charging the battery well or is not charging at all.

How to charge a VAZ-2114 battery yourself

You need to know how to charge a VAZ-2114 battery not only if self-diagnosis shows error 8. Correct and timely charging of the battery will extend its life. To do this, follow the recommendations of experts:

1. Remove the battery and carefully go over it with a cloth, your task is to thoroughly clean it from dirt. Focus on the top of the piece.
2. Now check the electrolyte load indicators. According to service station workers, the electrolyte level should be between the minimum and maximum icons located on the battery case. If the electrolyte is not enough, it must be added to the norm.
3. Charge the battery when the plugs are turned out with a current of 5.5 A. Also monitor the density of the electrolyte.
4. While charging, the battery can reach a temperature of 40 degrees, this is the maximum allowable value. However, experts believe that even this figure is too high - it is necessary to lower it to 27 degrees by interrupting battery charging.
5. When should charging be completed? If a large volume of gas comes from the battery, the electrolyte voltage and its density are kept constant. 3 measurements are taken as a basis.
6. If the density is different, then it needs to be adjusted. The increased density can be reduced by adding distilled liquid to part of the material. If it is low, use the method of adding electrolyte with increased density.
7. When the adjustment has been made, do not remove the battery from charging for up to half an hour, then turn it off and check the electrolyte readings after half an hour. If the material level is too high, use a rubber blower to remove excess material.

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.

How to replace generator brushes

To get rid of error 8, which occurred in the VAZ-2114 due to worn alternator brushes, follow these instructions:

1. Remove the wiring harness.
2. Disconnect the rubber cap from the terminals of the plus wires, which is designed to protect the part. To do this, unscrew the wire fixing nut and remove the wires from the generator housing.
3. Remove the black casing, made of plastic, by disconnecting 3 fasteners on spring mechanisms located along the perimeter of the block.
4. Find the regulator responsible for adjusting the voltage and use a Phillips head screwdriver to unscrew it.
5. All that remains is to pull out the regulator along with the brushes attached to it, and then disconnect the wire block.
6. Now replacing the brushes will not be difficult.
7. Installation of the updated VAZ-2114 voltage generator is carried out according to the same instructions, but in reverse order.

Removal and modification

Here's a quick look at the device and control panel icons. If for some reason she refuses, don’t immediately panic. Most often, the reason is the absence of contacts in some place in the wiring. But of course, if you wish, you can completely change or tune the panel.

For example, remove the cover and replace the light bulbs with brighter LEDs. Such a panel works brighter and the signals sent by the car will be more noticeable to the driver. If desired, you can install a more solid europanel, which will transform the interior. To remove the panel you need:

1. Disconnect the “-” wire from the battery;
2. Remove the shield by unscrewing the screws;
3. Remove the fastenings of the control panel to the trim, remove the instrument cluster from the socket;
4. Remove the glass mask;
5. Disconnect the wires from the block;
6. Make changes to the instrument panel or replace it with a new one. Reassemble everything in reverse order.
