Lada Kalina comes off the VAZ assembly line with a built-in central electronic control unit and an injection engine. All problems that arise in electrical and electronic systems are recorded by the control unit, stored in memory, and issued as a digital code.
Some errors are displayed on the screen of the combined instruments, and a more in-depth search for errors and their decoding is carried out by external devices, such as scanners or using computer diagnostics. Third-party devices are connected via the diagnostic connector. The fault codes on an 8 valve vehicle are identical to those on a 16 valve vehicle, with some additions.
Self-diagnosis
Before contacting a car service, you can independently determine in which of the nodes or on which of the highways the malfunction occurred. This can be done using self-diagnosis, when errors occurring in the electronic control unit are displayed on the control panel. Maybe you can fix it yourself, or at least understand what you are faced with and what to expect when contacting specialists.
This is a simple procedure. It is enough to reset the instrument data of the daily mileage by holding the Reset button and turning on the ignition. The devices will switch to test mode, during which the indicator lamps and backlights will light up, and the device arrows will move back and forth along the scales. On the steering column lever, on the right, menu items are switched, in which there is a self-diagnosis mode for devices. Information about the software version and digital error codes stored in the memory of the control unit will appear on the screen.
There are tables for deciphering errors. Exit from the self-diagnosis mode occurs within the next 30 seconds, during which no manipulations need to be performed.
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.
Deciphering error codes during self-diagnosis
Error code | Error interpretation |
2 | The on-board computer indicates that the network voltage is higher than permissible. It is necessary to check the power supply circuit and start the starter, check the battery and generator connections. |
3 | Failure of the fuel level sensor installed in the gas tank. Reasons: thinning of the contact group track due to friction of the slider, broken circuit, faulty float inside the tank. |
4 | Incorrect data is provided from the coolant sensor. Sources of malfunction: oxidation of connector contacts, low battery, damaged power circuit. |
5 | The outdoor temperature readings obtained from the sensor device do not correspond to real values. Sources of problems: water or dirt on the sensor, faulty electronics control device, poor contact. |
6 | Engine overheating detected. Sources of the problem: the thermostat or sensor has become unusable, the radiator or cooling line is clogged, the seal of the cooling system is broken, a defect in the fan. |
7 | There is insufficient oil pressure in the unit's lubrication system. Malfunctions: oil is leaking from under the rubber filter gasket, breakdown of the engine oil sump, unreliable attachment of the block to the oil pressure sensor, sensor wiring is damaged, the oil pump is out of order, the engine crankshaft liners are worn out. |
8 | Signal about inoperability of the brake system or leakage of brake fluid. Reasons: insufficient level of brake fluid in the reservoir, wear of brake pads, discs, drums. |
9 | Low battery signal. Check the electrolyte level, charge the battery. |
E | an error in the data packet embedded in the volatile memory chip. Reason: worn out EEPROM cells. |
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.
Diagnostics using third-party devices
For a more detailed check of the vehicle's performance, scanners and computers are used. They are connected to the diagnostic electrical connector (socket) located on the standard panel. Malfunctions are issued in the form of a standard set of alphanumeric codes, consisting of one letter and four numeric designations. The letter indicates specific nodes in which the malfunction occurred.
B - detects problems with electronics inside the cabin;
C - indicates defects in the chassis design;
P - errors in the engine control module or transmission;
U - loss of communication between electronic modules.
The letter designation is followed by four characters:
- the first character indicates a standard code established by engineers at the Automobile Association;
- the second character records personal codes set by manufacturers;
- the third character indicates which system the malfunction occurred in:
1-2 - in the fuel and air system;
- in the ignition system;
- in a secondary emission control system;
- in the speed control controls or when the load is off (XX);
- on-board computer system and wiring;
7-8 - errors in the operation of the gearbox;
9.0 - reserve;
- the fourth and fifth symbols are considered together to more accurately locate the point of failure.
How are errors diagnosed?
If problems and unusual malfunctions begin to appear in the usual operation of your car, think about carrying out diagnostics of the systems. Remember that not every machine has special pads for working with a specific professional connector, so it makes sense to use a standard connector. Why is code combination analysis so important? It is displayed on the on-board computer monitor, clearly demonstrating the problem and its location, which helps the owner to quickly carry out repair work. For a more detailed scanning of the breakdown, you can connect a special device - a scanner connected to the connector.
Self-diagnosis of the car
The system makes adjustments independently, automatically. Its structure includes other electronic devices. Thanks to special ECU sensors, the device’s memory receives information, including faults (shown in the form of numerical combinations). Most often, manufacturing companies are reluctant to provide complete information about the designation of codes and ciphers, as they consider professional inspection and care to be of better quality than independent care.
Experts recommend contacting the Lada service center to avoid fraud. Most cars are equipped with a bot controller - a unit that processes the information received by the sensors and displays it on the monitor. The Lada model does not have such a device, so it is appropriate to use scanning equipment. Let's take a closer look at the process itself:
- turn on the ignition, press “Reset” (needed in order to reset the mileage for the last day), hold it for a while;
- A self-diagnosis mode, segment icons, and indicators will appear on the instrument panel. The arrows will start moving;
- you need to switch between selected modes using a button located under the steering wheel on the right side;
- press the “errors” mode, reset them - hold down the above button for a little more than 3 seconds;
- Return from the set mode will occur automatically if the device is in idle mode.
How to diagnose via the dashboard
Diagnostics can be performed via the instrument panel. In order to start the verification process, it is recommended to click the button for recording the car mileage per day. Hold it a little and slowly turn on the ignition. If the manipulation is performed correctly, the instrument panel arrows (tachometer, speedometer, other indicators) will move in a circle, shifting from beginning to end. When the process is complete, switch the screen to another position using the button on the wiper adjustment surface (located at the bottom of the steering wheel). When you press it, an icon with the operating parameters of the ECU devices will appear on the instrument panel. One more thing: software with the inscription “self-diagnosis” always appears.
Diagnostics using a computer
For self-diagnosis, you can also use a laptop or PC. It is convenient to use a tablet. All you need is a USB cable to connect to the device and a previously installed testing program. There are a variety of firmwares, for example, a service for VAZ, developed specifically for certain car models (including Kalina). Connect the cable to the special connector located under the gearbox using the lever. Exact location: place above the cigarette lighter. The algorithm is like this:
- install the service on the device;
- in front of the lever, open the plastic cover, open the K-Line outlet;
- connect the wire to the block. Connect the first edge to the connector, the second to the gadget;
- You can start diagnostics and check the connection. Go to the “Tasks” menu, click the “Hardware” tab, view the connection. If it is, continue testing;
- start the firmware process. Monitor the reading of codes by the service; if this does not happen, click the “File” button, click the “diagnostics” field. A table with fault codes will pop up on the screen;
- There is a “parameters” button in the menu, which indicates the general condition of the car. If you need to view faults, click the “Codes” button.
When all the information is displayed on the monitor, it needs to be decrypted. The next steps are clear: a reference book or technical table is used, and the problem is resolved using the information provided.

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
Read also: Nissan Pathfinder low beam lamp
3. Then, after turning on the LCD indicator, you need to press the “mileage” button again once. The indicator display will then show the program version;
4. Error codes, if any, will be displayed in the top two lines;
5. In order to return the system to working condition, there are two ways:
•press any of the buttons on the control panel;
•wait 15-30 seconds. and the system itself will return to working condition, however, when choosing this option, you do not need to press the buttons.
Below is a breakdown of the codes that may appear on the panel:
1. Code 2 – on-board network overvoltage;
2. Code 3 – fuel level indicator (open circuit);
3. Code 4 – coolant temperature indicator, also an open circuit;
4. Code 5 – the external air temperature sensor has failed;
5. Code 6 – engine overheating;
6. Code 7 – oil pressure level is too low;
7. Code 8 – the vehicle’s brake system has broken down;
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.
