Decoding error codes Lada 4×4 (VAZ 2121, 2131)

April 30, 2020 Lada.Online 52 040 8

The fault indicator (Check Engine) on Lada 4×4 cars (VAZ 21214, 21314) is located in the instrument cluster. When the warning light turns on, it signals to the driver that the on-board diagnostic system has detected a malfunction of the ECM and the vehicle continues to move in emergency mode. To determine the cause, you should use a diagnostic tool, with which you can read error codes and decipher them according to the table below.

To carry out repair and maintenance work on the vehicle's engine management system, a diagnostic tool should be used. In service centers this can be a DST; for self-diagnosis, an ELM327 OBD-II scanner (price about 200 rubles, see the AliExpress catalog) and a smartphone with installed software (for example, OpenDiag), or an on-board computer installed in the car, are suitable for self-diagnosis.

VAZ error codes - table with a list of all errors

Very often, various errors occur in VAZ cars, and in fact, it is not necessary to go to a mechanic to diagnose them; it is enough to read the error code and look at its value in the error table.

The error codes are the same and apply to the following VAZ brands:

1118 Kalina, 2104, 21041, 2105, 2107, 21074, 2109, 21093, 21099, 2110, 21102, 21103, 2111, 2112, 2113, 2114, 21114, 21124, 21 15 with engine injector 8 and 16 valves, 21150 , 21154, 2131, 2170 Priora, 2190 Granta, 2123, 21214, 2131 Niva;

Self-diagnosis

If it is not possible to check with a special device, then this can be done using self-diagnosis, which will help to quickly identify all problems associated with the operation of the car. To do this, press the odometer button and turn on the ignition. The speedometer needle will begin to rise to the top; by pressing again, information about the firmware will appear on the screen, and by pressing again, all existing errors will appear.

Let's take a closer look at the Chevrolet Niva error codes with decoding:

During self-diagnosis, error 8 and error 14 often appear, the first informs about problems in the brake system, and the second is related to fuel consumption, quite often this is a system glitch, but in any case you need to replace the sensor responsible for these mechanisms, or reset the memory by resetting the battery terminals.

As practice shows, knowing how to perform an independent check is very useful, since this knowledge helps to quickly identify a malfunction and eliminate it in a timely manner.

VAZ error table

1. On a car with the engine turned off, disconnect the connector with contacts from the controller. Then you need to turn on the ignition, but do not start the power unit. You will need a multimeter to check the voltage between the contact elements.
2. The sensor connector is equipped with five pins, counting from left to right when viewed from the side of the air flow from the filter. Between contacts 2 and 3, the nominal voltage should be 10 volts, between 3 and 4 - 5 V. If there are deviations, the user needs to diagnose the integrity of the electrical circuit for breaks and current leakage.
3. At normal values, the ignition is turned off and the resistance between the “ground” and the fifth pin number is checked. The resulting parameter should be about 4-6 kOhm. If the value obtained is 0 Ohm, the sensor must be replaced; the problem may also be a short to ground. If the resistance parameter is 100 kOhm, then the cause must be sought in a break in the power supply circuit or in the engine control unit.

• regular use of low-quality fuel;
• violation of air intake tightness;
• lack of spark;
• damage or physical wear of cylindrical devices.

If replacing the fuel does not help, it is necessary to diagnose the air intake system. It is necessary to tighten the fastening clamps, change the air filter element and check the pressure in the rail (the normalized indicator is no more than 2.8 atm). It is also necessary to perform diagnostics:

• high-voltage wires connected to the defective cylinder;
• spark plugs;
• check for possible oxidation at the cable connection points.

Diagnostics of high-voltage wires is carried out using a tester; it is necessary to check the resistance. If the obtained value is more than 10 kOhm, then the cables must be replaced. You also need to check the integrity of the spark plugs and make sure that there is no carbon deposits on their tips. If the described actions did not help determine the cause, the cylinders are diagnosed. The user needs to check the compression level, which should be approximately the same in each device. If the obtained values ​​differ by more than 0.5 atm, then the power unit needs to be tested in more detail.

What's the result?

Ease of use and accessibility allow adapters for the diagnostic connector to significantly simplify the procedure for checking a car, reading and decoding ECU errors. It is also worth noting that the error can be quickly reset without having to disconnect the battery terminals, erase a critical error, etc.

Finally, we would like to add that among the commercially available adapters, there are devices that may not read errors recorded in the ABS unit and Airbag airbag modules. In other words, information on these items may not be available. For this reason, before purchasing an adapter, it is necessary to separately clarify the possibility of reading errors from the memory of the above and other ECM modules by one or another device.

Chevrolet Niva error codes: decoding and description of meanings

The popular Russian-made model is very widespread in the CIS countries due to its optimal cost and increased cross-country ability, which is critically important in the conditions of domestic operation. Motorists buy cars for off-road travel and small towns, where the quality of roads leaves much to be desired.

The disadvantages of the car include weak wiring - when the load increases to the design limit, on-board electronic systems often fail, which causes software failures. Chevy Niva error codes appear on the dashboard display or are detected using special equipment, but the common thing is that they all indicate a malfunction of a specific component.

What and how can you check the lambda?

Catalytic converter overheating. If the lambda is faulty, an incorrect signal is sent to the ECU. This may cause the catalyst to malfunction. It overheats until it turns red and fails.

Indirect signs of sensor malfunctions are unstable operation at low speeds, increased fuel consumption and low dynamics. It must be remembered that these external signs accompany malfunctions of the injection system and malfunctions of the ignition system.

As a result of a failed sensor, the quality of the fuel mixture entering the combustion chamber deteriorates, which disrupts the smooth operation of the engine.

If you find it difficult to determine the malfunction of the exhaust system of your car, then the best way to solve the problem is to contact a car service center in Nagorny to identify the malfunction and repair the exhaust system of your car.

Chevrolet Niva error diagnosis

The most reliable way to identify what is wrong with a car is to diagnose electrical appliances and equipment. The procedure allows you to accurately identify breakdowns and quickly repair your car.

There are two ways to detect a problem in a car.

Self-diagnosis VAZ 2123

The simplest procedure allows the motorist to independently identify the damaged area and repair the damage. Thanks to the successful firmware of the on-board computer, some errors are displayed on the standard display. In this case, nothing happens on its own - you will need to perform several steps manually:

• turn off the engine and turn off the ignition;
• find the daily mileage reset button on the dashboard and press it;
• at the same time turn the key in the starting cylinder;
• if everything is done correctly, all the indicators on the dashboard will light up, and the instrument arrows will make a full circle and return to their place;
• at the same time, the firmware version of the on-board computer will be reflected on the built-in display;
• The next press of the key will display a network error.

If the manipulations are correct, one of the indicated codes will appear on the display, and each Niva Chevrolet error number will be responsible for its own section of the highway:

• 0 – error 0 Niva Chevrolet indicates that there are no problems in the on-board circuits; most likely, the breakdown is purely mechanical in nature;
• 1 – standard error of the Niva Chevrolet ECU – the processor is not working correctly;
• 2 – for a Chevrolet Niva, error 2 indicates a lack of power to the gas tank float;
• 4 – malfunction of the battery or generator; a critical excess of the rated voltage of more than 16 volts was detected in the on-board circuits;
• 8 – has the opposite meaning; on a Chevrolet Niva, error 8 indicates an excessive voltage drop in the wiring due to a deep discharge of the battery or a malfunction of the generator;
• 12 – error 12 Chevrolet Niva reports a breakdown of the control indicator;
• 13 – signal transmission from the lambda probe is disrupted, you need to check the device and main power lines;
• 14 – on Niva Chevrolet, error 14 indicates a critical antifreeze temperature, the system requires cooling, otherwise the power unit may boil;
• 15 – the motor is too cold for normal operation, usually the error disappears after a good warm-up or replacement of the sensor;
• 19 – malfunction of the DPKV, the encoding indicates an incorrect speed of rotation of the unit;
• 21/22 – the throttle position differs from the calculated values ​​up/down;
• 23/25 – the air mixture on the intake manifold is excessively cooled or overheated;
• 24 – open circuit of the speedometer, accompanied by a lack of response of the instrument needle to the driver’s manipulations;
• 27/28 – incorrect display of the actual amount of exhaust from the calculated value;
• 33/34 – Mass air flow sensor, the indicators of the device are overestimated or underestimated, relative to the actual state of the system;
• 35 – incorrect operation of the engine at idle, you need to check the correctness of the mixture formation settings;
• 41 – the phase distribution sensor or DPRV has detected an open circuit or the data received is erroneous;
• 42 – multiple misfires were detected, the system turned off the fuel supply to the damaged cylinders;
• 43 – the detonation channel sensor generates an error;
• 44/45 – fuel mixture is too rich/lean; you need to check the fuel lines for mechanical damage;
• 49 – the vacuum gauge is out of order or overloaded;
• 51 – ROM has failed, or there is a breakdown in the power cables;
• 52 – RAM is not working correctly, damaged, no power;
• 53 – the adsorber purge valve is faulty;
• 54 – octane corrector controller is de-energized or broken;
• 55 – the calculated load on the internal combustion engine differs from the established one;
• 61 – the oxygen quantity controller in the intake system transmits incorrect data to the computer.

At the same time, you need to accurately understand that, for example, when error 10 is on the display, the Chevrolet Niva tells the driver that there are several problems (standard, unambiguous codes are summed up).

You should also know that Niva Chevrolet self-diagnosis errors do not reflect the exact location of the breakdown. Codings can only show the section of the wiring where you need to look for the cause of the malfunction. Also, these encryptions may be the result of a software failure after an unsuccessful wash or disconnection of the battery. To obtain more accurate data, the user needs to connect a special diagnostic scanner.

Other reasons

Reasons not directly related to the condition of the engine control and regulation systems may include problems with air supply systems, exhaust gas outlet systems, and fuel quality.
The condition of the intake system is affected by the conditions in which the vehicle is operated. When driving in dusty areas, the air filters should be replaced more often than the manufacturer recommends.

When the filter is “clogged,” the combustible mixture in the engine combustion chambers becomes depleted. Incomplete combustion of fuel occurs, or, as they say, the engine overflows. Soot forms on the spark plugs and the traction characteristics of the engine deteriorate.

If during operation the fastening of the intake system elements becomes loose, air leaks occur, exhaust gas recirculation systems do not work properly, the fuel mixture becomes lean due to excess air, and the engine does not develop full power. In this situation, it is necessary to check the condition of the fastening of the intake manifold and carburetor.

Exhaust system

Attention! If the car has a catalyst, then start checking the exhaust system with it. Check the condition of the lambda probe, the condition of the catalyst, whether it is “clogged” (due to poor quality fuel, carbon deposits may form on it). If the catalyst is faulty, exhaust gases will not completely exit the cylinders, which will lead to poor filling of the combustion chambers with the air-fuel mixture and a decrease in engine power.

If the seal of the exhaust manifold to the cylinder block is broken, exhaust gases will leak into the engine compartment, which can lead to engine overheating and incorrect operation of electronic systems. This problem can be corrected by tightening the manifold or replacing the gaskets under the intake manifold.

The engine spark plugs will tell you about bad fuel: if there is a red coating on the spark plug contacts and the “skirt” of the central electrode, then the fuel is good. Black carbon deposits on the spark plug indicate low quality fuel with a high content of impurities. The presence of soot impairs the quality of the spark plug.

Sometimes drivers say: the engine pulls poorly, the car does not reach maximum speed. Where to look for reasons? There may be several of them: - severe overheating of the engine; - faulty ignition system: the ignition setting is broken (ignition is too early or late); the centrifugal ignition timing regulator has become stuck; there is a malfunction in the vacuum ignition timing regulator; - insufficient filling of the cylinders with the working mixture; - interruptions in engine operation; - loss of compression in the cylinders; - entry of a lean working mixture into the cylinders.

If the engine does not develop full power, then it is best to check the serviceability of the ignition system. Note that if the ignition is too late, the engine loses throttle response and overheats. A significant reduction in power occurs due to the fact that the mixture does not have time to burn at the moment when the piston is in. m.t.

The combustion of the mixture continues as the piston moves downward; this is easy to determine by touching the exhaust manifold with your hand. It will be too hot because some of the mixture will burn when released. Too early ignition also has a harmful effect on engine operation, when the combustible mixture ignites prematurely and the force of the gases acts towards the piston, which moves towards the engine. m.t.

At the same time, frequent and loud metallic knocks are heard in the engine, the engine is prone to fuel detonation, does not work well at low speeds, and sometimes backfires when starting with the crank. Having established that power is lost due to ignition being too early or late, adjust it.

If it is not possible to achieve the desired results by adjusting the ignition timing, it means that there is a malfunction in the automatic ignition timing adjustment devices; centrifugal or vacuum regulators. It must be remembered that the centrifugal regulator regulates ignition timing only depending on the engine speed.

It usually starts working at 400-600 engine rpm. If malfunctions occur in the centrifugal regulator (weakening of the springs or sticking of weights), this will lead to disruption of the ignition timing. If the regulator weights jam, the ignition timing will remain the same at both low and high speeds.

Meanwhile, for high speeds, the ignition timing should be earlier. Late ignition at high speeds will cause a decrease in power and increase fuel consumption. If the regulator springs are weakened and the weights disperse completely, then even at low speeds there will be a large ignition advance, which will also lead to excessive fuel consumption and a decrease in power.

Usually the serviceability of the centrifugal regulator is checked using a synchronograph. But, as a rule, there are no instruments on the way. However, the operation of the centrifugal regulator can still be checked. How it's done? Without removing the distributor from the engine, you need to move the breaker lever and turn the cam by hand in the direction of rotation of the shaft until it stops.

The weights are moving apart. Release the cam and it will return to its original position under the force of the weight springs. If jamming is detected, it must be eliminated and the weakened springs replaced with new ones. From the above it is clear that the centrifugal regulator regulates the ignition timing only depending on the speed.

But on the way, the car has to move along different roads - flat and with inclines. Let us assume that when driving at a constant speed both on a flat road and on an uphill road, the centrifugal regulator will only provide the same ignition timing. While the engine load and throttle opening are significantly greater when driving on an uphill road, the ignition timing should be less than on a flat road when driving at the same speed.

The ignition timing is adjusted when the throttle opening (engine load) changes by a vacuum regulator. It may have the following malfunctions: - loss of spring elasticity; - air leakage into the spring plane; - jamming of the ball bearing of the breaker panel. When the vacuum regulator spring is weakened, at low and medium loads the ignition timing increases.

If air is sucked into the cavity where the spring is located (if the diaphragm is damaged), then the ignition timing will decrease at low loads. If there is too much air leakage, the vacuum regulator does not work at all. The vacuum regulator may also fail due to a stuck ball bearing on the breaker panel.

Like a centrifugal regulator, a vacuum regulator is usually checked for serviceability using a synchronograph. On the way, you can check it in the simplest way: rock the breaker panel on the bearing and make sure there is no excessive clearance, and also determine whether there is an increase in the gap between the panel finger and the diaphragm rod, and whether the rod itself is jumping off.

If you create a vacuum in the vacuum regulator tube disconnected from the carburetor, then if it is in good condition, the breaker panel should turn in the opposite direction of rotation of the cam. Having discovered that both advance angle regulators are working properly and the ignition is set correctly, the reason for the decrease in power must be sought in insufficient filling of the cylinders with the working mixture.

This may be caused by the throttle valve sticking on the axle (not opening it completely). You should check the throttle valve drive and, if necessary, remove jamming and clean the axle. Then make sure the air filter is working properly. If it is dirty, disassemble it, wash it and, if necessary, change the oil.

It is advisable to check the serviceability of the valves and springs of the gas distribution mechanism; in case of violation of the gaps or breakage (loss of elasticity) of the valve springs, weak and broken springs should be replaced, the gap should be adjusted. Insufficient filling of the cylinders with the working mixture can occur when the needle valve of the float chamber is stuck, a faulty muffler, the use of the wrong grade of fuel, as well as in the case of a large deposits of tar and coke in the intake pipe.

A common cause of incomplete engine power is the entry of a lean mixture into the cylinders. Reasons for the formation of a lean mixture: - the jets and channels in the carburetor are clogged, contamination (water freezing) of the fuel lines in the power system has occurred. Rinse and blow out the jets and channels, blow out dirty fuel pipes, and if necessary, clean them with wire; - stuck fuel pump valves or clogged sump mesh, a small rupture of the diaphragm.

First, eliminate the jamming of the fuel pump valves, wash the filter element and mesh, and replace the torn diaphragm with a new one or restore the functionality of the old diaphragm in the manner described earlier; - air leaks at the junction of carburetor parts, the carburetor flange with the intake pipe, the intake pipe flanges with the cylinder block due to loosening of fastenings, as well as damage to gaskets.

You can find the location of the leak using a match or soap foam. The flame of a match, brought to the intended place of suction, is deflected towards the gap, and a window is formed in the soap foam. Air leaks are eliminated by tightening the nuts or bolts, as well as replacing the corresponding sealing gaskets; - wear of the fuel pump drive lever, clogging of the air holes of the fuel tank filler plug, jamming of the air damper.

These defects are eliminated as follows: faulty parts of the fuel pump are replaced with new ones, the air holes of the plug are cleaned, the length of the choke control cable is checked and, if necessary, adjusted. Relatively often, the reason for a decrease in engine power is a drop in compression in the cylinders.

Diagnostics using third-party equipment

More precisely, errors on Chevy Niva can be identified by connecting additional equipment. The technique is more technically complex, but allows us to determine the cause of a breakdown or failure with minimal error. In this case, the sequence of actions is as follows:

• turn off the engine;
• find the contact connector under the dashboard, the connector is located at the bottom of the steering column;
• connect the configured computer to the ECU output;
• turn on the ignition;
• follow the program instructions.

If all actions are performed correctly, all available information and any errors in the form of encrypted codes will be displayed in the desktop window.

There are also specialized scanners designed specifically for Chevrolet NIVA. Dealer devices are connected to the place of the standard signaling unit through an output cable.

Separately, we should highlight modern devices designed to connect a smartphone to a car, while reading encodings and controlling operating modes occurs directly from the gadget’s display.

At the same time, you should know what the encodings displayed during diagnostics mean. The code consists of several elements.

• P – the motor electronics have failed;
• C – there are problems with the chassis;
• B – interior space, a problem has been detected;
• U – there are problems when establishing pairing of on-board systems.

The next element is a single digit:

• 0 – OBD 2;
• 1-2 – standard code of the manufacturer;
• 3 – reserve part of electrical equipment.

The following digit determines the exact serial number of the line in which the defect was detected:

• 0 – exhaust system device;
• 1-2 – violation of the fuel or air supply device to the engine;
• 3 – ignition does not work correctly;
• 4 – additional equipment control;
• 5 – monitoring the engine idle state;
• 7-8 – transmission and chassis design.

You can learn more about where the VAZ camshaft sensor is located and how to replace it in a garage from the video below (the author of the video is Vitashka Ronin).

The Chevrolet Niva diagnostic connector helps you obtain information about how most units work, into which special equipment is connected via Bluetooth or a cable. Therefore, if you want to conduct independent diagnostics, it is important to know where it is.

The connector in the Niva is located under the steering wheel on the right side, and the pinout itself is under the dashboard on the driver’s side. To check the on-board computer, you need to use special equipment that transmits all the necessary information to the laptop. Data transfer is carried out using a COM port into which a K-LINE type connector is installed.

When connecting, errors may appear on the laptop screen. At this moment, there is no need to worry, since the appearance of such messages may be due to a lack of communication with the device itself. You should also check whether the standard anti-theft system is installed; if so, check the adapter itself. If there is a standard location, then it is connected to the diagnostic line between the ECU and the immobilizer. And if it is missing, a plug is installed in its place. To restore communication between the contacts, a jumper is installed, as shown in the picture below:

Depending on the year of manufacture of the model, the connectors may differ from each other.

Chevrolet Niva error reset

The standard procedure for resetting the controller occurs only after all faults have been completely corrected, otherwise annoying encryption will appear again. The procedure is performed in two available ways.

1. Disconnect the battery from the on-board network for 10-15 minutes. The controller will completely reboot and return to factory default settings.
2. In the BC menu, enter the “errors” service, press the daily mileage reset button and wait for the sound signal from the car, and horizontal lines should appear on the display.

The most common Niva Chevrolet computer errors are found in 90% of car diagnostic cases. There are also a large number of rare failures that are not included in the list due to their low prevalence.

What does the Check Engine Light mean?

Sometimes it can be a very minor problem - for example, a loose gas cap or a faulty catalyst. However, you should not ignore the indicator signals under any circumstances, as this can result in serious problems.

The Check indicator may light up for various reasons.

Sometimes the cause of the indicator light may be poor fuel quality. So don’t be surprised if, after refueling at an unfamiliar gas station, you see the Check Engine light flashing.

Typically the indicator is located on the car's dashboard under the engine speed indicator. It is indicated by a schematic engine or a rectangle with the inscription Check engine or simply Check. In some cases, instead of an inscription, a lightning symbol is depicted.

Is it possible to continue driving while the light is on?

The brake pads are worn out, it's time for the next maintenance, the speed is switched incorrectly, low-quality fuel is used, the on-board voltage has dropped - all this can cause the Check indicator to light up. First of all, you should check the motor. If the reason for the signal to turn on is due to engine malfunctions, it is dangerous to continue driving.

The problem is aggravated by the fact that it is impossible to independently determine the malfunction of a modern internal combustion engine by smell or color. You should contact professionals who will use a scanner to identify the malfunction, if, of course, there is one.

Look at the article in the new section “Computer Diagnostics”. She is now the top in the news.

In general, the corresponding error code will pop up.

I have this problem: there is gas in the field (GIG 3L), so it has 2 modes, automatic (with an oxygen sensor) and manual ("bypassing" the sensor), so for some reason it doesn’t matter, I started driving on gas (in automatic mode), it just flies on gasoline, so I think it could be an oxygen sensor. How to check it?

Do-it-yourself lambda decoy for Shniva

Outdated sensor models are easily deceived, and setting the resistance is quite simple. The resistor connection diagram is shown above. To install the “add-on”, the sensor wire is broken and an additional element is soldered in.

Difficulties arise with cars after 2010 release. The software of such cars has already been updated and such manipulations will not lead to a positive result. Car enthusiasts have come up with a new way to trick the controller. To do this, a special unit is soldered to the sensor, which collects data from the sensitive element and, after processing, sends it to the BC.

A similar device can be found on the Internet; along with the snag, a diagram of its connection and assembly of the entire module is supplied.
