Error codes for Lada Kalina: self-diagnosis of the on-board computer and decoding 0504, 0830, as well as p0441, 0036 and others

Lada Kalina is already equipped from the factory with a special on-board computer mounted directly into the instrument panel. Thanks to this, you can react as quickly as possible and diagnose the problem that has arisen. There is a self-diagnosis mode for this. Unless the previous owner was motivated by selfish goals and “turned out” these light bulbs, in which case they need to be replaced.

The video shows entering the diagnostic mode of the on-board computer on the Lada Kalina:

Errors are shown as a digital code and in this article we will tell you how to read them correctly and make the right decision.

Diagnosis of errors

When you begin to notice something unusual in the behavior of your car, or there are obvious problems in its operation, then it certainly makes sense to have it diagnosed. Naturally, the OBD-II diagnostic connector will show errors most efficiently and accurately, however, not everyone has sockets to control this connector and has to use the standard one.

In order to enter self-diagnosis mode, you must:

Turn off the ignition.
Click on the daily vehicle mileage button.
Then, continuing to hold it, turn the key in the lock.
Thanks to this, all available indicators will light up, and the dial indicators will go into self-test mode and show data from zero to maximum.
When this happens, use the button located on the steering column switch and use it to switch the data on the instrument panel.
To read the fault codes, we need the last one - the third screen. Unambiguous error codes will be displayed there.

Error codes (decoding)

These are the most common error codes that can appear if there is a malfunction on the Lada Kalina.

Code	Decoding
2	Exceeding the voltage level in the vehicle's on-board network.
3	Malfunction of the gasoline level sensor in the fuel tank. Possible circuit break.
4	When this code appears, the car owner needs to pay attention to the operation of the antifreeze temperature sensor. There is also a possibility of a circuit break.
5	There is a problem with the outside temperature sensor.
6	The control unit has detected engine overheating. It is recommended to deal with this problem before further operation of the car.
7	Emergency lubricant pressure in the internal combustion engine is reported.
8	If you see this code on the dashboard, then you need to check the functionality of the brake system. The on-board computer recorded an error or breakdown in its operation.
9	The on-board computer reports that the battery charge is too low. It is recommended to perform a more thorough check of the battery.
E	An error has been reported in the data packet stored in the EEPROM.

Checking the system using special equipment

If the system is checked through a diagnostic block using OBD-II, then the code combination will consist of four characters, preceded by a letter at the very beginning.

P - indicates a problem with the engine or transmission.
C - displayed when an error occurs in the “running”.
B - when such a letter designation appears, you should pay attention to the serviceability of the central locking system, airbags, and power windows.

The second digit means:

0 – common code for OBD-II;
1 – number of the car manufacturer;
2 – number of the car manufacturer;
3 – reserve code.

The third character refers directly to the type of failure:

1 – malfunction in the air supply system and fuel system.
2 – similar to code “1”.
3 – failures and malfunctions in the ignition system.
4 – auxiliary control.
5 – malfunctions during idle operation.
6 – malfunction of the ECU or its circuit.
7 and 8 – malfunction in the transmission.

In order to delete the error code that appears from memory, you need to hold down the daily mileage button and hold it in this position for more than –4 seconds.

Decoding error codes Kalina 1.6 8 and 16 valves

Many owners of this model will be interested in knowing how error codes for Kalina 1.6 8 and 16 valves are deciphered. The on-board computer installed in the car not only controls the operation of the car's systems, but can perform self-diagnosis and inform the driver about any malfunctions in the car. This significantly increases safety and increases the service life of machine components and assemblies. Every driver of this model must be able to deal with emerging alarms in a timely manner.

Decoding error codes for Kalina 1.6 8 and 16 valves will be shown in this article.

You can make a printout and take it with you. If suddenly an alarm signal appears during a trip, it will be much easier for the driver to make the right decision about what to do in the situation that has arisen, continue the trip or wait for help from specialists. The system works in such a way that errors from problems that arise are stored by the on-board computer. They can be read later using special diagnostic equipment.

How to perform diagnostics yourself?

Sometimes even the most reliable and smart cars malfunction during operation. This can fully be attributed to Kalina. The on-board computer of this model is capable of analyzing the current situation and telling the driver about problems. You can test the car in specialized centers or yourself. There is a possibility of errors during self-diagnosis, but it is advisable to carry it out.

Self-check procedure:

Turn off the ignition;
It is necessary to press the daily mileage button and hold it in this position for some time;
While holding this button, turn on the ignition;
After this, all the indicators on the dashboard should move, they should travel from the zero mark to the maximum. Now you should press the button on the steering column wiper switch. This makes it possible to display readings on the dashboard.

Self-diagnosis mode on Kalina 2

Self-diagnosis of the instrument panel on the 2nd generation

What is a liquid crystal display or indicator? liquid crystal display, or LCD for short, is a flat-shaped display based on liquid crystals. So, it was not in vain that I started with LCD indicators, since we will talk about the LCDs installed in the Lada Kalina.

An indicator installed on the dashboard displays information processed by the on-board computer. The amount of information displayed depends on the vehicle configuration.

This screen displays the following information:

1. Current time or number of the suggested manual transmission gear (or automatic transmission mode);

2. It also shows the total mileage of the vehicle or mileage during one day(s);

3. Displays data on the external temperature or one of the indicators (the latter depends on the vehicle configuration);

4. Fuel level.

In order to start the self-testing mechanism in a Lada Kalina car, you must:

1. The battery must be connected;

2. It is necessary to hold down the car daily mileage reset button and turn on the ignition

Diagnostics using the dashboard

It is advisable for the owner of the Russian model we are considering to remember all the error codes that may periodically occur in the system. In addition, it is recommended that you learn how to diagnose the dashboard yourself. It is designed to reflect error codes that occur in the electronic components of the Lada Kalina.

To start the diagnostic process, you will need to press a button that records the daily mileage. While holding it, turn on the ignition by turning the appropriate key. If this manipulation is performed correctly, the arrows on the scales of the speedometer, tachometer and auxiliary indicators will begin to move along a circular path, moving from the initial to the final position.

Upon completion of this movement of the arrows, the owner will need to switch the screen to another mode. This will be done by a special button located on the wiper switch under the steering wheel. Pressing displays a picture with performance indicators of a wide range of devices controlled by the ECU. The software version of the complex is also displayed here - self-diagnosis.

After updating the information three times, the error codes themselves appear on the device, expressed in digital form.

Let's look at the list of errors by number:

The “E” symbol deserves special attention, which indicates the presence of errors contained in the “EEPROM”. Each malfunction, including error 4 and error 8, requires attention from the car owner.

Troubleshooting

The Lada Kalina has a central control unit for the injection engine and vehicle electrical system. Problems that arise during the operation of electronic and electrical systems are recorded by the unit in the form of errors and stored in memory. If there are such problems, the orange Check Engine light on the panel lights up. Some errors can be displayed on the screen installed on the instrument cluster and deciphered.

Code analysis allows you to accurately determine the incorrectly operating element and repair or replace this unit. You can check for problems more deeply and thoroughly by connecting a special scanner to the diagnostic connector. The diagnostics and list of errors are the same on a 16-valve car and on a car with a simpler 8-valve engine.

Step-by-step self-diagnosis

Checking for errors in the ECU and displaying their numbers on the dashboard is called self-diagnosis. This procedure is not complicated and can be easily done independently.

In this case, the owner of a Lada Kalina 1118 station wagon or sedan must perform the following actions:

Get behind the wheel of a Lada Kalina car and press the daily mileage reset button on the instrument cluster (Reset).
Turn on the ignition while holding the button pressed.
The instrument cluster will switch to test mode, during which the full backlight will turn on, all indicator lamps will turn on, and the device arrows will begin to move smoothly in both directions along the scale.
Using the button on the right lever of the steering column switch, you can sequentially change menu items, including self-diagnosis of devices, software version (firmware, inscription like Uer x. x) and error codes in the unit’s memory.
It is necessary to look at the codes recorded in the ECM and determine their meaning.
To exit the self-diagnosis mode, you need to wait about 30 seconds without performing any actions.

Kalina steering column switch button

The modernized Kalina 2 has a slightly different instrument panel design. The procedure for displaying errors is similar; codes appear in the top line of the display as a three-digit number. Below the indicator line, information about the vehicle's serial number is displayed (looks like a six-digit number).

It is important to note that sensor problems are recorded in memory only if there is a long-term absence of a communication signal with the device (more than 20 seconds). For short-term breaks there will be no error, although there is a malfunction in the car.

Fixing breakdowns

After the diagnostic procedure, and determining why the VAZ Kalina 8 valves are capricious, it is necessary to completely check the entire line of the unit, which is indicated by the decoding of the index. This must be done by testing the main line and replacing the blocks with known good ones. Additionally, the specifics of operation should be taken into account - due to constant shaking on broken roads, the standard terminals can become loose, which provokes a breakdown in contact. In this case, the computer will also indicate the presence of a malfunction. In order to prevent this, experienced craftsmen recommend treating connectors with special impregnations that repel water and carry out preventive maintenance in a timely manner.

Decoding combinations

Errors read on the standard panel of the on-board computer can be deciphered using the table. It is useful to print out such information and carry it with you in the glove box, since breakdown of car sensors can happen on the road. Many problems can be corrected only during repair work in a car service center. Knowledge of the decoding will allow the owner to control the process of repairing his car.

Self-diagnosis codes

When diagnosing, you can read the fault codes listed in the table from the instrument panel. Please note that several errors may be displayed simultaneously during the verification process.

Below is a complete list of self-diagnosis errors.

Code on screen	Decoding
2	Excess voltage in the on-board electrical network
3	No signal in the circuit from the fuel level sensor
4	No signal from the internal combustion engine temperature sensor
5	The signal from the sensor measuring the air temperature outside the car is not detected
6	Raising the engine temperature above the permissible level
7	Critically low oil pressure in the engine lubrication system
8	Brake fluid leak or failure of the system's electronic components
9	Excessive reduction in battery voltage
E	EEPROM data error

Controller errors

For more complete diagnostics, the car needs to be checked with a KKL VAG-COM for 409.1 scanner. To do this, you need the scanner itself and a laptop with the pre-installed Diagnostic Tool v. 1.3.1., which allows you to view all the vehicle’s operating parameters and find out possible problems. Error codes received by such devices will consist of four numbers and a letter located in front of the numbers.

It should be remembered that each letter is responsible for a certain part of the machine components:

B - indicates errors in the electronic components of the car body (window lifters, microclimate);
C - errors in chassis components (power steering);
P - malfunctions in the engine or automatic transmission control systems.

The video, shot by the author of CompsMaster, clearly demonstrates the connection of a test laptop to the diagnostic connector and shows the functionality of the program.

Another way to control the ECM is the additional on-board computer State, which is connected directly to the diagnostic connector and installed on the center console. This device is capable of reading almost all operating parameters of various vehicle systems. There are several types of State computers, which are selected according to the model of the ECM unit.

In addition, one of the most common errors on the Lada Kalina is P 0441, indicating an insufficient volume of air supplied to purify the absorber. This problem causes the check lamp to come on after prolonged driving and does not affect the driving performance of the car. Malfunction P 1602 is no less common; it signals a loss of voltage to the ECM and is recorded in memory after the battery is disconnected.

Errors in lambda probes and their heating systems are common. For example, 0036, which indicates a failure of the electrical heating of the sensor. The solution to this problem is to replace the sensor or install a decoy. As changes are made to the design of cars and new options become available, the list of error codes for the Lada Kalina is constantly expanding.

Secondary parameters of motor operation

Engine idle speed test results

Throttle Position (THR) value. This parameter is determined by a special sensor. If the throttle position value shows an error and malfunction, the car owner may notice some jerks with “dips” while driving. An increase in the number of idle revolutions will also indicate the presence of a problem. This parameter should be checked with the ignition on, but it is not recommended to start the engine itself. When you gradually press the gas pedal, the readings on the monitor should smoothly increase to 90%. It should be taken into account that it is impossible to achieve 100% - this is predetermined by the manufacturers. The sensor is considered operational if the procedure was successful. Idle speed should show 0%.
Crankshaft and its rotation frequency (FREQ). The diagnostic figure will be displayed on the screen by a special crankshaft position sensor. The malfunction is easy to notice even without diagnostic equipment, because the engine simply will not start. Indicators from the sensor normally vary in the range from 800 to 840 rpm.
Limit of uneven crankshaft rotation (LUMS_W). This figure should not exceed 4 rpm. Otherwise, you can be sure that there are misfires in the cylinders. With such a malfunction, it’s time to check the spark plugs and high voltage wires.
Ignition timing (UOZ). Data from several sensors are combined into one indicator and calculated by the electronic control unit. The value varies from 6 to 15.

This is the way to check engine operation using a diagnostic connector and special equipment. Digital code records are formed from symbolic symbols of car faults. They can be seen on the dashboard dial.

Reset errors

If necessary or after correcting problems, the driver can delete the error from the control unit’s memory. To do this, you need to activate the service mode, enter the error codes menu and press the Reset button, which should be held for at least 3 seconds. After this time, the codes will be discarded. Deletion is indicated by a message like “——” on the instrument cluster screen.

Controller errors can be reset using software. Typically, this procedure is carried out during regular vehicle maintenance.

conclusions

It turned out that finding and eliminating the cause of error 4 in Lada Kalina is quite simple. Although deciphering error codes requires specialized knowledge, you can find the necessary information in this article.

The Lada Kalina car is equipped with an on-board computer that allows you to quickly diagnose any problems that may arise. Thanks to the control unit, you can find out about car breakdowns thanks to the read codes. In this article we will tell you what the most common Kalina error codes are and how to diagnose it yourself.

What to do?

Let's look at ways to eliminate the main faults that cause the check on Kalina to light up (8 and 16 valves) in the same sequence as the causes of the problem.

A broken oxygen sensor requires replacement. If this malfunction is ignored for a long time, the catalyst will become a further victim. As a result, subsequent repairs will cost a tidy sum.

In case of insufficient tightness of the gas tank closure, the cap is checked for cracks and tightness. If the check goes out after a certain distance after intensive screwing, then the problem has been resolved. It should be remembered that the tank cap needs to be changed from time to time.

If the catalyst is faulty, fuel consumption increases significantly and engine thrust decreases. Definitely, in this case the check will remind you of this. To fix the problem, you will need to replace the catalyst. It is better to entrust this expensive procedure to experienced craftsmen, since delay is fraught with more serious problems with the need to invest significant funds.

Timely replacement of spark plugs will prevent the Check Engine sensor from lighting up due to contamination or wear. Experts advise changing these elements after 25,000-30,000 km. mileage High-voltage wires require similar attention, the failure of which can also cause the activation of the check indicator.

On Kalina 8 and 16 valves, replacing the mass fuel flow sensor does not pose a serious problem. Although you can drive with a faulty element for quite a long time, fuel consumption and the blinking of the check mark will remind you of the need to install a new part. This procedure will not take much time and will not require significant funds. Timely replacement of the air filter continues the life of the sensor in question.

Trouble P0441 - Evaporative Emission System - Incorrect Purge Flow

Trouble code P0441 indicates a problem with the evaporative emission system. Other error codes may also appear along with this code.

What does P0441 mean?

Trouble code P0441 indicates that the ECM has detected incorrect purge flow in the evaporative emission control system. If the purge flow is incorrect, the Check Engine Light will illuminate on the vehicle's dashboard. The ECM uses a vacuum switch to determine purge flow.

Causes of error P0441

Missing or damaged fuel tank cap
Vacuum switch malfunction
Damage to the fuel vapor recovery system tubes
Short circuit or broken wires
Blockage of the fuel vapor recovery system
Fuel vapor leak
Purge valve malfunction

What are the symptoms of a P0441 code?

Typically, when the P0441 error appears, drivers do not notice any signs of its occurrence at all. In rare cases, you may smell fuel inside or outside the vehicle.

How does a mechanic diagnose a P0441 code?

First, the mechanic will connect the OBD-II scanner to the vehicle's diagnostic port and read all the stored data and error codes.
He will then clear the error code from the ECM and test drive the vehicle.
If P0441 appears again, have a mechanic visually inspect the evaporative emission system.
The mechanic will then check the fuel pressure sensor in the fuel tank for damage.
He will also check the fuel cap.
He will then check the operation of the vacuum switch and purge valve.
If no problem is found, the mechanic will perform a thorough check of the evaporative emission system to check for leaks.

Common errors when diagnosing code P0441

The most common mistake when diagnosing a P0441 code is not following the diagnostic protocol, as well as not performing a smoke leak test.

Also, mechanics often assume that the problem is a damaged fuel cap, but do not perform thorough diagnostics to verify this. It is imperative to check the fuel tank cap for leaks, for example using a vacuum tester.

How serious is P0441?

Error P0441 is not considered very serious. However, it should be noted that if the Check Engine Light comes on, the vehicle will most likely fail an emissions test. Also, when this error appears, drivers may smell fuel.

What repairs can fix the P0441 code?

Replacing the fuel tank cap
Repairing a leak in the fuel vapor recovery system
Repair or replace damaged evaporative emission system components
Replacing the purge valve
Vacuum switch replacement
Repair or replacement of wires

Additional comments for troubleshooting P0441

To properly diagnose the P0441 trouble code, a mechanic will need an advanced OBD-II scanner. It is necessary to check the operation of the vacuum switch and purge valve, as well as to carry out certain tests.

In some cases, a smoke leak test may be necessary to detect a leak in the evaporative emission system. This test can help detect even the smallest fuel vapor leak. The fuel tank shall not be completely empty or completely full during this test.

What is the essence of this system

"Toyota": error codes and decoding

Kalina's automatic fault diagnosis system includes several devices. The display displays information that is processed by all devices. To prevent car owners from having to independently service their cars, manufacturers do not try to talk about the location of the devices and their decoding. This is explained quite simply: if a car owner who does not have the proper experience decides to repair the Lada Kalina on his own and without the advice of specialists, seeing error 0441 on the display, then he can only worsen the technical condition of his “four-wheeled friend.”

Since the Lada Kalina does not have an on-board computer, the owner will only be able to visually familiarize himself with the code number, and he will have to guess the location of the breakdown on his own. In order to avoid mistakes when repairing your car, experts recommend knowing each code by heart in order to promptly eliminate any type of malfunction.

Old spark plugs and high voltage wires

If the engine light comes on, you need to check the spark plugs. They perform an important function; they participate in the ignition of fuel in the engine. If the spark plugs are faulty, then the spark is not supplied to the gasoline mixture. If there is no spark, the car may not start or the engine may not operate properly. Incorrect operation of the spark plugs leads to small tremors.

Car service specialists recommend replacing spark plugs after 25-30 thousand kilometers, especially if the car is old. However, the service life of spark plugs is directly influenced by the quality of the fuel and driving style. Faulty spark plugs are usually very noticeable.

The car starts with difficulty.
Fuel consumption increases.
The catalyst fails.

Check the fuel filler cap

Many drivers, in most cases, when the “check engine” indication appears, will think about serious problems in the car’s engine, but will not even think to check the tightness of the fuel system, which may be compromised due to a defect or an insufficiently tightened fuel tank cap. This is a very common reason for the appearance of the “Check” engine icon.

Reason for the error: Leakage of the fuel system due to the passage of air through the filler cap of the fuel tank will increase the vehicle's fuel consumption, to which the vehicle's diagnostic system will generate an engine error by turning on the "Check engine" indication on the vehicle's instrument panel.

What needs to be done: If, when the “Check” indication appears, your car has not lost power, and there are no audible signs of engine damage (engine knocking, humming, creaking, etc.), then first check the gas tank for leaks. Your gas cap may be cracked or not tightened enough. If the cap was not tightened enough, then after tightening it all the way, continue driving the car for a while to see if the engine error disappears. To prevent a check engine light from appearing for this reason, check your fuel filler cap regularly. Remember that the cover must be replaced with a new one periodically!

Failure of the fuel tank, failure of the neutralizer

When the check engine light comes on, the owner of a Lada Kalina with an 8-valve engine first of all aims to find faults directly in the engine. However, the reason can sometimes “lurk” elsewhere. The glow of the symbol is caused by a loss of tightness in the fuel circuit. Even a loose tank cap can cause this situation.

Depressurization of the system involves the penetration of an additional portion of air into the circuit. In this case, a symptom such as an increase in fuel consumption appears, and the correct functioning of the engine itself is also disrupted.

When the owner of a Lada Kalina does not detect any extraneous sounds in the engine or other deviations in its operation, but the lamp on the dashboard still continues to glow, then the first step is to make sure that the gas tank cap is tight. Quite often there are situations in which drivers, in a frantic rush, forget to check that the cap is correctly and securely seated after refueling.

If after such a check the lamp on the dashboard “refuses” to go out, then you need to continue searching for other reasons. What to do when the catalyst “announces” its malfunction? This important component of the exhaust system serves to neutralize the flow of exhaust gases. It is no secret that a huge number of substances harmful to the surrounding atmosphere accumulate in the exhaust system during engine operation. Due to the presence and functioning of the neutralizer, the level of their emissions is reduced significantly.

Among the main signs of a breakdown of the catalyst in Lada Kalina, 2 experts highlight the factor of reduced engine power. This also manifests itself in worsening dynamics.

As already noted, a common reason for the neutralizer to become unusable is the breakdown of the lambda probe in the Lada Kalina 2. Also, worn-out spark plugs can significantly shorten the “life” of the exhaust circuit element considered here.

As a result of the influence of these factors, a significant decrease in the effect of gas neutralization is observed. Oxides accumulate inside the component, which over time leads to overheating and the risk of catalyst destruction. Operating a car with such a breakdown is undesirable, since incorrect operation of the engine will not allow the unit to develop the declared characteristics. Over time, a neutralizer that has become unusable can cause damage to the power plant, so timely replacement of this component is a more rational and cheaper measure compared to engine overhaul. To replace it, you will need to contact a service center, since it is unlikely that you will be able to carry out the repair procedure yourself.

Let us remind you that the keys to a long service life of the neutralizer are:

timely replacement of spark plugs;
use of high-quality fuel;
correct operation of the lambda probe.

Another factor if the check light is on is the failure of the sensor responsible for the mass flow of air sucked into the intake manifold. This malfunction is characterized by a decrease in the engine power level and the failure of the unit to start smoothly when cold.

Why can the mass air flow sensor fail? One of the reasons for this annoying situation is the untimely replacement of the filter element in the air intake circuit. The motor itself is unlikely to suffer from a faulty state of the sensor, other than the indicated loss of power parameter. However, the owner will refuel more, due to the increase in consumption provoked by this fact. The price of the mass air flow sensor is not exorbitant, so it is not advisable to delay replacement. The repair procedure itself is not difficult to perform. This can also be done at the service center during scheduled maintenance.

Replacing lamps - nuances

Sometimes it is difficult to say which light bulb on model 2114 has lost its functionality. In this case, everything is pulled out and checked with a multimeter. For this:

set the tester to ohms;
Press one probe against the side of the base, and the second against the blotch installed at its lower end;
If the arrow moves, then the filament coil is working.

It is important to remember that the described procedure is not suitable for diode lamps. A different operating principle is used here.

The multimeter must be switched to diode testing mode. The probes are connected in the same way, but during testing they change places - in one direction the current flows without restrictions, and in the other direction it is not allowed to pass at all.

A tester is required for one reason - the light bulb is very small and it is almost impossible to determine the serviceability of the filament purely by eye. The measuring device helps to quickly cope with the task.

Experienced car enthusiasts advise replacing all the lamps at once after disassembling the instrument panel, because they are inexpensive. Otherwise, there is a risk that one or more old ones will soon burn out, and all the work will have to be done again.

When the new lamps are installed, return the instrument panel to the interior, connect the wires to it, but do not fix it. Further:

turn on the ignition;
check how the backlight and indicators (handbrake, turn signals, etc.) function.

If everything turns out to be in order, then fasten the panel with screws.

How to choose the right service for diagnostic and repair work

In the age of computer technology, information about self-diagnosis behavior is widely available. Private salons and services are not uncommon, as are craftsmen working on the road. If a problem arises with the operation of your car, it is important to understand whether you can fix the problem yourself or whether it is better to seek the help of a professional. Not all workshops have licensing documents from the manufacturer or certification to provide services. The result of dishonest work will be poor functioning of the ECU or other components of the diagnostic system.

You have every right to demand documentation confirming the qualifications and professional level of employees, their ability to handle special equipment and the electronic system of the car. For computer diagnostics, it is important to have the appropriate equipment, for example, a stand with which work is carried out in parallel with a laptop. It is thanks to the stand that the information will be more accurate and a comprehensive picture of the condition of the machine will be revealed. You should not pay money to specialists who offer the service of flashing the on-board computer or controller to change the technical characteristics of the car.

Many modern cars have the ability to independently read electrical system problems. Error codes on Kalina, after decoding, can reduce the time required to find a faulty unit in the electrical wiring.
