Error codes that are logged as errors by the engine control module memory belong to a specific type of diagnostic information. The interpretation of codes is useful for any owner, including the owner of a Lada Kalina.
Through these encrypted information units, the process of self-diagnosis of all on-board electronic components in the car is carried out. This is very useful because it provides the ability to identify a malfunction before a critical failure of a system component occurs.
Carrying out diagnostics on Lada Kalina
When the usual operation of your own car begins to be accompanied by the appearance of problematic symptoms, and various types of problems arise, then you should think carefully about how important it is at the moment to carry out diagnostic measures for all systems.
It is always useful to remember that you can always use a standard connector, since not every car has special devices that allow you to work with a professional and specific connector.
- It is very important to analyze code combinations, since in this case both the problem itself and its location are clearly represented by displaying a message on the monitor.
- This is a good help for the car owner, who can then carry out the appropriate replacement or repair. A scanner is attached to the connector for convenience. It makes scanning the problem the most extensive and detailed.
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 license 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 machine’s condition 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.

Self-diagnosis
Adjustment actions are carried out automatically by the system without outside help, for which it is equipped with all the necessary electronic devices. Special purpose sensors transmit data to memory, including numerical combinations that indicate faults.
In most cases, the designation of codes is not always fully provided for when care and inspection activities are carried out by professionals.
To avoid being hooked by scammers, you should use the services of service specialists whenever possible.
The Lada model does not have an on-board controller, which provides information to the monitor device after it has been processed. Therefore, scanning techniques are used in practice for these purposes.
The process looks like this:
- After turning on the “ignition” function, you will need to press “Resert” and hold it for a while. Thus, the mileage for the last twenty-four hours will be reset;
- The dashboard will display both the self-diagnosis mode and indicator symbols along with the “icons” of the sections. The arrows will begin to move;
- On the right side under the steering wheel is located in order to be able to switch the desired mode;
- After pressing the “errors” mode, they must be reset once, after which this button must be held down for more than three seconds;
- When the device is no longer used, it automatically returns from the selected mode.
Location of the ECU in Lada Kalina
The electronic control unit is located under the center console on the driver's side. To access it, just remove the protective panel. It is worth noting that the location for the ECM was chosen very poorly. The ECU under the console often fills with coolant, because the heater radiator and hoses are in close proximity. Therefore, many motorists strive to move it to a safer place as soon as possible.
Dashboard. Diagnostics
You can perform diagnostic steps using the dashboard. The verification process starts after clicking on the button, which is designated - fixing the distance traveled in twenty-four hours.
Hold it lightly and slowly turn on the ignition function.
- If the manipulations are carried out correctly, then all indicator devices, including both the speedometer and the tachometer, will make a full circular rotation from the initial position to the final one.
- Once the process is complete, the screen switches. For this purpose, there is a button located below the steering wheel, on the surface where the adjustment for the wipers is located.
If you click it, an icon will appear that displays the operating parameters of the instrument devices. In addition, an additional software tool will be displayed, where there is the inscription “self-diagnosis”.
Diagnosing the block
After dismantling the liquid-filled module, we inspect it. To do this, take a screwdriver with a star tip and unscrew the 4 small screws. Next, we slowly remove the control board, with which we also perform a thorough visual inspection.
The most common reason for device failure in such a situation is a burnt-out output key of the Lada Kalina ignition coil control circuit. Repair won't help here. After such a malfunction occurs, the engine begins to function on only two cylinders, and in some situations it is not able to start at all. This is where qualified service will come to the rescue. Specialists will dismantle the damaged component, wash and dry it.
The second common cause is burnout of the board itself. This fact is revealed quite simply. There will be a characteristic darkening of the surface of the board, which will eliminate all doubts.
Will repairing the ECU help in this case? The answer can only be heard in a specialized workshop. From experience, we note that the probability of help from repairs tends to zero. Will need replacement.
Sometimes there is a situation related to minor damage to the ECU circuit. In this case, the owner can get away with little expense. To “reanimate” the module, you will need to perform a number of repair procedures, namely:
- wipe the device with a dry cloth;
- apply repeated washing with WD-40 and blow with a stream of compressed air;
- rinse again, but with alcohol and also blow with an air stream;
- Dry (thoroughly) for at least 2 hours.
Some Lada Kalina owners believe that replacing the ECU is a faster and more cost-effective process compared to washing and drying. Experience has shown that the situation is the opposite. Here the determining role is given to the price factor. The new ECU will require considerable financial resources from the owner of LADA Kalina. The situation is aggravated by the undesirability of installing used “brains”. Often, a used version of the unit will be cheaper, but there is a likely risk of it not working.
Fault codes. Decoding
Four characters indicate the error code. The letter designation that is displayed in front of them is the local designation of the place where the malfunction occurred.
I designate these signs as follows:
- “B” indicates problems in the body part, such as electrics, windows up and down, central locking, airbag malfunction;
- “C” is associated with problems in the chassis or more minor ones in the suspension. It may also turn out that the electric power steering has failed;
- “P”, as the symbol most often encountered during the control process, means that either the transmission has broken down or the reason is in the power unit.
The number located after the letter designation is associated with:
- The standard OBD code is 2 – “0”;
- The sign of the company that produced the car is “1”;
- Icon ;
- The code designation of the reserve is “3”.
As for the third symbol, it is this that indicates the malfunction and its type:
- The detected malfunction in the fuel unit or in the air supply system is “1”. Designation of the system's response to the fact that there is too much voltage inside the on-board compartment;
- “2” indicates that the fuel system is not in order. The problem in this case turns out to be the fuel tank sensor. In addition, it may indicate that a break has occurred in both the sensors and their circuits;
- The on-board computer device detects system malfunctions for the ignition as “3.”;
- Auxiliary control is designated "4". This includes regulating functions for the system, along with coolant temperature;
- If there are problems with a malfunction in the external temperature indicator, this is indicated by “5”. The vehicle will be checked at idle speed;
- Malfunction in the electrical circuit – “6”. Notification using an acoustic indicator that the engine has overheated;
- The computer will indicate the transmission and the breakdown in it as “7” or “8”. The pressure is in this case at a dangerous level for the oil. It could also mean a minor problem with the brake system;
If the battery is discharged, this will be indicated by the number “9”.
Basic design of the self-diagnosis system
The automatic fault diagnosis system on the Lada consists of several devices. It is the information received from them that we later see as fault codes. Typically, the manufacturer does not recommend self-service to car owners and therefore the location of some of them is not disclosed.
This is done so that dishonest people cannot, for example, “twist” mileage figures or somehow change engine characteristics before selling the car. For the same reason, it is recommended that servicing of the self-diagnosis system be carried out only at official service stations that have the appropriate permission from the vehicle manufacturer.
In addition, another element of the automatic diagnostic system is the on-board computer. It is he who processes the information collected by the sensors, which we then read as Lada Kalina error codes. At the same time, there are different versions of such systems that allow, for example, to visually represent the location of detection of a particular defect.
Unfortunately, Kalina does not have such a computer, and its owner can only see a digital designation of a particular malfunction. That is why every car owner needs to remember the errors of the Kalina on-board computer by heart in order to take timely measures to eliminate this or that malfunction.
