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.

Diagnostics

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

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

Decoding combinations

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

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

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

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

Diagnostics using additional tools

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

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

Adapter for car diagnostics

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

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

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

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

Decoding combinations

If problems arise with electrical equipment, they must be corrected immediately. Error code 1602 will indicate that not everything is in order in this matter.

Sometimes error 1602 can simply be reset and does not appear in the future. Socialists call such data “good.”

Error 1602 sometimes appears if:

• the battery was disconnected for some time;
• there was a voltage surge when starting the engine, for example, in cold weather.

But if error code 1602 appears all the time, you need to check the entire network. Perhaps there is a break. If error code 1602 constantly appears, you can try cleaning the battery terminals. Check if they are securely fastened. Didn't help, error 1602 still appears? Check the circuit. You need to start from the positive terminal of the battery. Start with the electrical fuse and fuse link.

Decoding fault codes for Lada 2110 for 8 and 16 valves: table

The code that is displayed on the device usually consists of one or two digits. The VAZ 2110 has computer diagnostics available, which allows you to display errors consisting of letters and more numbers as visible on the panel. The list of codes that you most often encounter during self-diagnosis is presented in the table below. Decoding of five-digit codes is available on the screen of a special scanner.

Error 1

The motor control unit is faulty. The reason lies in the oxidation of the contact connector or its breakdown. If the module is broken, you will have to reflash it.

Code 2

Evidence of increased voltage in the car network. Battery operation needs to be checked.

Code 3

The electrical circuit of the fuel level sensor has failed. This is due to broken wires or poor contact.

Code 4

If the check shows this error, look for the reason in the antifreeze controller and its wiring.

Code 5

The external temperature controller is faulty. The reason may be a bad connection or it will need to be replaced.

VAZ 2110: error 6

The motor has overheated. You need to turn it off and wait for it to cool down.

Error 7

The engine fluid pressure has reached an emergency level. The sensor may be faulty.

Error 8: Lada 2110

The voltage in the machine network has dropped below the permissible level. The problem lies in the contacts, wiring integrity or improper battery operation.

The battery is discharged and requires recharging.

Fault 10

Occurs when the wiring is broken and there is a subsequent voltage drop in the fuel level sensor system.

Breakdown 12

The diagnostic power line of the indicator located on the instrument panel may not function properly.

Breakdown 14

If the error appears on a VAZ 2110 16 cl, it means that there is an increased signal from the antifreeze temperature sensor. Often the problem can be corrected by cleaning the contacts, but sometimes the controller may need to be replaced.

VAZ 2110: code 45

The mixture in the cylinders is too rich. The sensor may need to be replaced.

Error 0102

Occurs when the signal level in the mass air flow sensor circuit is too low. If error 102 is visible, then most likely the culprit is damaged insulation or poor contact.

0103 - malfunction

Occurs if the signal in the same circuit, on the contrary, is too high. The reason is the same as in the previous case. Attention should be paid to the reliability of the connection between pins 7 and 12 of the injection system harness pads.

Code 0113

P 0113 indicates that the intake air temperature sensor has failed. Faulty contacts or oil contamination of the indicator are to blame.

Breakdown 0118

Appears if the coolant temperature sensor signal is too high. The reasons for the failure are the same as in the previous case.

Fault 0122

Appears when the signal in the throttle position sensor circuit is too low. The reason is a lack of voltage due to a damaged wire.

P0123 - error

The throttle position sensor “A” produces an increased signal level. To fix it, you need to replace the controller's electrical connector or repair the wires.

P0134 - code

The oxygen sensor does not produce a signal. Occurs due to damaged wire insulation, poor contact or air leaks.

Fault 0171

It speaks of an excessively lean mixture and occurs when the lambda probe begins to fail. The reason lies in air leaks or cracks in the crankcase ventilation pipes. A broken air temperature sensor may be to blame.

Breakdown P0172

An over-enriched mixture is supplied to the cylinders. Occurs due to incomplete combustion of fuel. The reasons are poor performance of spark plugs, oxygen sensor or air flow controller.

Code 0300

Appears when the piston stroke has not occurred in one of the cylinders. Occurs due to damage to the insulation on the wires or moisture getting into the connectors or oil into the electronics.

Code 301

Indicates misfire in the first cylinder. The reason is air leaks, broken elements of the fuel supply system or ignition module. An insulation breakdown often leads to this result.

Fault 0327

Associated with a reduced signal from the knock sensor. The reason is problems with contacts, but sometimes a sensor failure is to blame.

Breakdown 0328

Indicates an increased signal from the knock sensor. The reasons for the appearance of the code are often the same as in the previous case.

Breakdown 0335

Indicates an incorrect signal from the crankshaft position sensor. Faulty wiring and resistance are to blame. In some cases, code 335 indicates a sensor failure.

Error P0340

Problems in the camshaft position sensor circuit. Except in rare cases, 340 indicates a problem with the wiring or electronic control unit.

Code P0343

Appears when contacts are oxidized or insulation is broken in the camshaft position sensor circuit.

Occurs if abnormal voltage values ​​are observed from the battery. Corrosion of the terminals, damaged wiring or breakdown of the generator is to blame.

Error 0562

Indicates low voltage in the vehicle's on-board network. The reasons for the occurrence are the same as in the previous case.

Breakdown 0501

Incorrect speed sensor readings:

• failures in the CAN bus;
• wiring faults;
• Speed ​​sensor drive malfunction.

The reason is a broken speedometer - this is where you should start checking.

0601 - error

Appears when there are problems with the internal memory of the motor control module. Indicates problems with the module or low voltage in the network, the cause is local wiring failures and global generator malfunctions.

Code 0603

It indicates a failure of the external RAM. Most often it is enough to erase it. If it appears again, the internal test controller will need to be replaced.

Code 1135

Occurs if problems are detected in the fuel mixture sensor circuit. The reason for this may lie either in a short circuit or a malfunction of the device.

Error 1206

Occurs in the power unit system and indicates a cylinder miss. A number of reasons can lead to its appearance, ranging from a vacuum leak to an ignition malfunction. When it appears, it is better to contact a service station.

The cause and elimination of the problem is complicated by the fact that, due to the characteristics of the circuit, it is difficult to localize the location of the breakdown. It is necessary to carry out diagnostics, since a malfunction will lead to accelerated wear of electronic systems.

Error 1621

RAM code P1621 occurs when the electronic control unit is disconnected from the network, electrical interference or a malfunction of the ECU itself. It is recommended to check the contacts.

Error P2110

Indicates serious problems with throttle control. The damper itself will need to be replaced.

Step-by-step instructions for diagnosing a VAZ-2110 with your own hands

To carry out computer diagnostics of a VAZ-2110 car, it is recommended to contact specialized car services that have all the necessary equipment at their disposal. However, this approach has several significant drawbacks. Firstly, the procedure for identifying faults in a service station can be quite expensive. Secondly, unscrupulous technicians have a bad habit of embellishing the results obtained and claiming faults that actually do not exist.

That is why in this article we will look at how to do computer diagnostics of a VAZ-2110 with your own hands, provide detailed step-by-step instructions and help you minimize costs.

Crankshaft and camshaft

So:

• 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:

What is needed to diagnose a VAZ-2110

So, to check your car for faults, identify injector failures and on-board computer errors, you will need the following:

• an adapter designed to connect the ECU (electronic control unit of a car) with a PC, as well as display all the results obtained on the display of a tablet, smartphone or laptop. When purchasing an adapter, you should definitely take into account all the features of the car, since these devices are not universal. For VAZ-2110 cars, the ELM327 model would be an excellent choice;
• a cable that allows the adapter to be connected to a personal computer and the vehicle’s diagnostic connector. Its length should be no more than 5 meters, so be sure to take this requirement into account when choosing equipment for diagnostics;
• laptop or tablet. Many experts strongly recommend using a portable laptop computer, which will provide you with complete freedom of action in the process of carrying out diagnostic work;
• software. Its most current version can be easily found on the website of the adapter manufacturer or on specialized websites dedicated to the diagnosis and repair of the VAZ-2110.

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:

Features of computer diagnostics of a car

How is diagnostics carried out using all the equipment and software listed above? A detailed description of this procedure will help you answer this question:

• diagnostic software transmits a request to the car controller via the adapter;
• the controller, in turn, provides all the necessary information about the state of the main on-board systems of your car;
• the software analyzes the data and displays the result in the most readable form;
• Using information on the Internet, you decipher error codes obtained as a result of diagnostics and identify problems with certain components and mechanisms of the car.

Data is transferred to the computer via the ODB II protocol. It has a number of disadvantages, but the VAZ-2110 is quite suitable for diagnosing a car, since domestic cars are equipped with significantly less electronic equipment than modern imported equipment.

Main types of computer diagnostics

The adapter, which is connected to the on-board computer system and your laptop (or tablet), allows you to carry out the following types of diagnostic work:

• assessment of the technical condition of the engine. It will allow you to find out why the power unit suddenly loses its original power, and will also help you understand why fuel consumption increases and problems arise with starting the engine;
• suspension diagnostics, which is simply necessary if problems arise with the maneuverability of the car, tires wear unevenly, or extraneous sounds appear while driving;
• checking the condition of the automatic transmission. You will not need this function, since the VAZ-2110 is equipped with “mechanics”. However, it is of great importance for diagnosing other machines.

How to independently diagnose a VAZ-2110

The last question that remains to be addressed in our article is the sequence of diagnostics of the VAZ-2110. It looks like this:

• connect the adapter to the ODB diagnostic connector, which is located under the steering column;
• turn on the tablet or laptop, on the screen of which the diagnostic results will be displayed;
• turn on the car ignition. To check the engine and suspension, as well as to display the necessary information on the display, a mandatory power supply to the on-board network of the machine is required;
• launch the software and get the results of diagnostic procedures;
• We decipher error codes and determine malfunctions of certain components and mechanisms of the car.

As you can see, there is nothing complicated in self-diagnosis of the VAZ-2110. You can easily navigate all its intricacies without having the appropriate knowledge and skills, you will be able to identify existing problems without contacting car services, and you will be able to significantly reduce the financial costs of servicing your car.

Computer diagnostics

For computer diagnostics of the VAZ 2110, you will need a KKL adapter (other names 2KL, KL, K-line).

More often this adapter is found under the name “VAG Com 409.1 KKL”. In this abbreviation, “VAG Com 409.1” is the name of the program that comes on the disk along with the cable. This program is intended for diagnosing Audi, WV - it will not be useful to us.

To connect the VAZ 2110 to a computer, download and install the OpenDiag program.

In general, there are quite a large number of programs for connecting a VAZ using a KKL adapter, you can install everything and choose the one you like. OpenDiag is a free program, the project is in constant development. New blocks are constantly being added and functionality is expanding. The program almost completely implements diagnostics of ECUs of VAZ family cars, as well as support for many ECUs of the GAZ/UAZ/ZAZ families.

How can you tell if your car is faulty?

There is a special lamp on the instrument panel with the inscription CHECK ENGINE. When you turn on the ignition, it lights up, and until you start the engine, a special program reads data from all systems and components of the car, thus transmitting data to the on-board computer to identify faults.

After you start the engine, the lamp should go out, but if it stays on for another 10 seconds, it means that some problems have been identified and error codes have been entered into the on-board computer programs. Communication with the controller is carried out using the diagnostic block.

VAZ 2110: rich mixture error

If the air-fuel mixture is over-rich, the following codes appear:

Malfunction - lean mixture

RAM Error 2110: What is it?

Codes related to the operation of the ECU.

Calculation of codes

Most often, diagnostic program codes are “deciphered” using a special device. However, on VAZs it is not so difficult to do it yourself.

ECU January 4 for VAZ 2110

The diagnosis itself goes like this:

• Connect contact “B”, which has the diagnostic block and “ground”;
• Turn the ignition key to the third position, do not start the car;
• First, the aforementioned “CHECK ENGINE” lamp flashes code 12 three times in a row. It, in fact, does not signal any malfunction, but simply shows that the diagnostic programs are working. On the VAZ 2110 this happens in this order: the lamp blinks briefly once (which should be considered the designation of number 1). After a pause of at least two seconds, it flashes twice in a row (two). So we got the number two. And this is repeated three times so that the driver can understand these signs;
• Now you need to be careful not to miss any faults. After the diagnostic program has declared its serviceability, it will begin to display error codes, if any. In the same way - flashes and pauses.

Installing a new adapter

Modern adapters elm 327 with the OBD-II program (puncture) are suitable for the VAZ 2110 . You can also install them yourself. First you need to purchase an elm 327 and a cable for it. You already know the location of the diagnostic connector. Be sure to study the instructions, which indicate the pinout of the block and the location of each connector.

Connection diagram for ELM327 to 12 PIN diagnostic block

The pad can be removed quite easily. Insert your own cable into each connector of the block, making sure that the pinout of the elm 327 complies with the manufacturer’s instructions. Check that each connector is connected correctly and each cable is in the correct place. After this, the block is installed in its place.

Connecting the diagnostic connector to the block

Fault detection programs for elm 327 can be downloaded on the Internet, many of them in a free version. Now your VAZ is ready to detect errors in various car systems, and you can always download error codes from us.
