Lada Kalina

About Model

Production of Lada Kalina began in 2004. The model range is represented by three types of bodies: station wagon, hatchback and sedan. The design of the cars is modern, wedge-shaped front end, smooth lines of the body and flat sidewalls add elegance.

"Kalina" has a spacious interior and a modern interior. Light plastic is used in the decoration, thanks to which the interior seems more comfortable. The front panel is made of hard plastic, but visually it looks great. The front seats are equipped with longitudinal adjustment, the rear row of seats can be folded in a ratio of 60:40. The station wagon trunk is adapted to carry large loads, which cannot be said about the luggage compartments of the hatchback and sedan.

The first models were completed with 1.6 liter petrol engines.

The car was produced in three configurations: "norm", "standard" and "norm +". The package includes two front airbags, electric power steering, belt pretensioners and force limiters, as well as ABS.

In 2013, there was a complete update of the Lada Kalina lineup. Has changed appearance car, it began to look more dynamic. The outlines of the line of doors, wheel arches, bumpers, hood, fenders and trunk have been transformed. Changed the location of the headlights, now they are higher.

The equipment has also been updated, the cheapest “standard” includes an airbag for the driver. The more expensive "norm" includes two airbags, ABS with a boost system emergency braking, air conditioning, audio system with Bluetooth and USB interface, as well as heated front seats. The top-end luxury version includes climate control, an audio system with a seven-inch LCD display, power windows on all doors and heated front seats.

Diagnostics of the Kalina engine is carried out by testing all systems and mechanisms in order to assess their performance, as well as to detect hidden defects and malfunctions.

Engine diagnostics is carried out sequentially, in several stages. First, a mechanical check of the condition of the electrical wiring, fuses and spark plugs, the reliability of the connection of connectors and pipelines is performed. The condition of units, components and mechanisms, sensors, filters, pumps, etc. is assessed.

After that, the identified malfunctions are eliminated, and then computer diagnostics of the ignition, fuel supply, lubrication, cooling and exhaust systems are carried out. First of all, the software is identified and the performance of electronic components, ignition coils, indicators, sensors, etc. is checked. in static mode.

After elimination of all malfunctions and malfunctions, computer diagnostics of the running engine is carried out.

Analysis of the results of computer diagnostics and drawing up a troubleshooting plan is carried out after printing the protocols.

Features of the operation of engines "Kalina":

The frequency of maintenance is 15 thousand kilometers.

The service life before the first repair of engines with the replacement of rings is 120-130 thousand km and 220-240 thousand km before the second.

CPG and shafts are working properly for at least 300 thousand kilometers.

Sometimes there may be failures of the sensors of the injection system.

TPS (throttle position) and DMRV (mass air flow) sensors often fail.

Diagnostics of the running gear Lada "Kalina"

Experts from Renault and Nissan companies took part in the development of the Kalina chassis. Most of the details and mechanisms of the "VAZ" suspension have been modernized and improved. Thanks to this, the smoothness of the ride, stability and controllability of the car has significantly increased.

The front suspension "Kalina" is made according to an independent scheme with telescopic shock absorbers, coil springs, transverse lower arms, stretch marks and anti-roll bars.

The rear suspension is based on two trailing arms, shock absorbers and helical coil springs.

The steering is reinforced with a rigid mount, thanks to which information content has increased. The car is easy to control in all modes.

Regular diagnostics of the Kalina chassis allows you to constantly monitor the performance of components and mechanisms, evaluate their suitability for operation, and also identify various malfunctions, breakdowns and defects. In the process of diagnostics, testing of the front and rear suspension, steering, brake system, and vehicle transmission is carried out.

Connector for machine motor diagnostics

Lada Kalina has a diagnostic connector when equipped with a self-diagnosis system, which is now installed on almost all modern cars. The presence in cars of such a connector is associated with the tightening of the rules for checking at technical inspections.

That is why the manufacturers of Lada Kalina began to equip the car's electronic systems with some diagnostic functions. Thanks to the connector, the diagnostic scanner can be connected to any brand of car, and also makes it possible to connect the appropriate devices for mileage cheating.

General characteristics of engine diagnostics

The purpose of the diagnostic connector is to allow you to connect the vehicle's control units and main components with a diagnostic scanner. Connectors have a certain number of pins, each of which has its own function and performs a specific task.

Engine diagnostics is carried out in order to identify hidden problems and defects, as well as to assess the performance of each mechanism.

Before checking the engine with a connector, you should subject the Lada Kalina car to other diagnostic methods. First, a mechanical check of visible parts (wiring, fuses and spark plugs) is performed and the condition of all important vehicle components is assessed. Only after this inspection and elimination of all identified faults, electronic diagnostics is carried out.

First check the fuses

Diagnostics Lada Kalina, which can be carried out using a connector.

1. View and read codes, identify errors.
2. Assessment of the operation of the control system, clarification of its characteristics.
3. Delete the results of previous checks.
4. Analysis of indicators of oxygen sensors.
5. Obtaining diagnostic data while driving.

Diagnosing an injection car only seems complicated and incomprehensible. Many people think that this is a job for trained and experienced craftsmen, but you can check the operation of control systems yourself.

Self-diagnosis of the car Lada Kalina

In any modern control unit, namely the one on Kalina, there is a fairly powerful self-diagnosis system based on programming. This greatly facilitates troubleshooting even for an inexperienced car owner.

The electronic control unit is a mini-computer that performs special tasks:

• processing of signals received from sensors;
• calculation of control effects according to given algorithms;
• management of correction mechanisms.

Self-diagnosis begins by connecting the diagnostic tester to the vehicle controller. This makes it easy to get diagnostic data and errors. Instead of a tester, you can use a special program by downloading it for free on any suitable resource.

To carry out diagnostics yourself, you need to purchase a K-line diagnostic adapter that supports the KWP200 protocol. It transfers data from the machine to the computer. For this, the Lada Kalina car has a special connector, which can be found next to the gear lever under the cover. At Kalina, the location of the diagnostic connector is the most successful compared to other models. The adapter should be connected to this connector.

The adapter for the connector comes with a special driver and software. The COM port that appears in the program must be rearranged to the numbers 1,2, 3 or 4. These are the numbers with which the standard Kalinovsky connector works.

After connecting the diagnostic connector and equipment, turn on the ignition and start the program. If everything is done and connected correctly, the system will display a message that the connection has been established. Now you can start diagnosing.

What are standard options

Diagnostic procedure

Each engine has its own standard parameters. These are technical specifications that determine the normal operation of the motor. These parameters are compared with the values ​​obtained during the diagnostics. All measurements are taken with the engine running. idling.

The presence of errors that have been stored in the vehicle's memory is the so-called DTC parameter. What kind of errors these are can be established when deciphering their codes, which are easy to find on any resource on the Internet. There are entire tables with interpretations of error codes.

But the engine may have failures and malfunctions and not give errors. For example, if the idle speed is too high, the control unit considers that the driver has pressed the gas pedal, does not perceive the situation as an error and, of course, does not issue it during diagnostics.

If during engine diagnostics all measured parameters differ from the typical ones by no more than 20%, then the motor is working normally. Units and parts whose performance exceeds the specified value can be considered faulty.

Key Performance Indicators

A complete analysis of engine operation will be checked

1. Battery voltage level (UACC). To carry out the test, all the most powerful sources of energy consumption must be turned on. If the voltage indicator on the diagnostic screen is less than it should be, you will have to check all electrical circuits separately. Normal values ​​are 14 to 14.5 V.
2. Mass air flow (AIR). The indicator determines the mass air flow sensor. Without diagnostic equipment, it is not possible to check the air flow. To obtain the value, you need to press the gas pedal so that the number of revolutions is 5000. With a working sensor, the indicator rises to a level of 200-250 kg / h.
3. Injection pulse duration (INJ). This is the time that fuel is injected into the cylinder while each injector is open. Higher than normal values ​​indicate that the nozzles are most likely clogged and clogged. To fix the problem, the parts should be flushed. Causes can also be a clogged fuel filter or a pump failure. To accurately diagnose the problem, press the gas pedal. Normally, the indicators should be from 3 to 5 in a calm, idle state and from 15 to 20 when gassed.
4. Oxygen index before catalyst (ALAM1). It should not exceed 0.7 V and, reaching this figure, go back down. This indicates the correct operation of the feedback.
5. Number of controller steps idling(FSM). In another way - the idle speed control sensor. It is a stepper electric motor with a plug in the form of a cone fixed on the shaft. When the engine is idling, this figure is 40-60 steps, while gasping - from 150 to 180 steps.
6. Estimated fuel consumption (QT). For a complete diagnosis, check the pressure in the fuel rail and the voltage in the spark plugs. It does not hurt to check the compression on the cylinders and find out the CO. However, for all these measurements, in addition to the diagnostic connector and standard equipment, you will need another, expensive device and the connection of experienced professionals to work. Therefore, here we will have to limit ourselves to one indicator: from 0.6 to 0.9 l / h at idle.

On a Kalina car, the diagnostic connector performs important functions. Almost all modern cars are equipped with an electronic control unit and a self-diagnosis system. It is a mini-computer programmed to perform certain functions. The tightening of the rules during the passage of TO led to the emergence of special devices. Equipped with electronic systems, Lada Kalina also received a diagnostic connector.

The main purpose of such a connector is to provide communication between car control units and a diagnostic scanner or laptop. Thanks to this, you can independently diagnose all car systems through a laptop at home. To do this, you just need to connect the gadget to the connector using a special adapter, then the diagnostic program starts.

Self-diagnosis of Kalina

When diagnostics are made with their own hands, Lada Kalina undergoes a full check, which begins with the selection of equipment:

• notebook;
• adapter (there is wired and Bluetooth, any will do);
• diagnostic program.

Next, we look for the connector located in the car. In Lada, it is located in a fairly convenient place, next to the gearshift lever. It is closed by a plastic cover on small latches. I would like to note that manufacturers are improving, and Lada Kalina 2 has received an even more convenient diagnostic connector, there is no need to even bother with latches. Just plug and play.

When the connector is found, connect the adapter to it. This should be done with the ignition off. If the adapter is wired, connect the other end of the cable to the laptop's USB connector.

We launch a special program for diagnostics. It requires the installation of drivers. We select in the options "set up a connection", we are all connected. Now we turn on the ignition, and the diagnosis of Lada Kalina can be considered started. Everything is extremely simple even for an inexperienced car owner.

Carrying out diagnostics on your own, you need to understand that there are standard boundaries for the indicators of car systems. And we focus on them in order to understand whether all the components and parts of the car are working properly. All measurements are made with the engine running at idle. And only such indications are compared with the technical characteristics of the normal operation of the car.

If the changes in indicators have deviations from the standard within 20%, then the operation of all systems is normal. When deviations exceed 20%, the components and parts in which this was found are considered faulty and require repair or replacement.

During the operation of the car, errors may occur that are fixed by the system.

Usually, when the control unit detects an error, the check engine indicator lights up. And this means that in order to understand what's wrong, you need to diagnose the engine.

Each possible error is assigned a code by which it can be deciphered. On the web pages you can find detailed analysis each code and understand what the fixed error is. The diagnostic program has a special section where these errors can be viewed.

The system does not always recognize a violation in operation and generates an error. Ongoing engine diagnostics will not show this problem. Therefore, during the check, you need to carefully monitor deviations in the operation of systems from the norm.

Having a diagnostic connector, Kalina has become even more convenient to maintain. Now that all the necessary data has been received, turn off the ignition. In the program, select the option "break the connection" and disconnect the adapter from the connector. This completes the diagnostics.

Diagnostic indicators

Before diagnosing the Lada Kalina engine through a connector, it is required to perform a visual inspection and a mechanical check and assess the condition of the main components of the machine.

Electronic diagnostics is aimed at identifying hidden malfunctions in order to evaluate each unit and part separately. With its help, we can analyze the performance of oxygen sensors, characterize and evaluate the operation of the control system, check for recorded errors, view the results of previously performed checks and delete them, and even receive data from a moving car, which is an important point, since many deviations in operation can only be detected in conditions of full load on the car.

Engine performance indicators include:

1. Battery voltage level (UACC). To check, simultaneously turn on all energy consumers in the car. The norm for the voltage indicator is within 14-14.5 V. If it is less, you need to check all electrical circuits separately.
2. Mass air flow (AIR). To check it, they press on the gas, bringing the engine speed to 5 thousand, if the value of the indicator has increased to 200-250 km / h, the mass air flow sensor is working.
3. Injection pulse duration (INJ). Check the discrepancy with the norm, simply by pressing the gas. It is considered optimal that the indicator fluctuate at idle about 3-5, and when you press the gas - 15-20. If it's higher than normal, then there's a problem.
4. Oxygen index (ALAM1). Its value should not be higher than 0.7 V. When it reaches this mark, the air should return, this will indicate that the feedback is working properly.
5. The idle speed control (FSM) steps should be around 40-60 when adding throttle, 150-180.
6. Estimated fuel consumption (QT). It includes several indicators, the verification of which requires special equipment and the participation of a professional. Therefore, at home, you can determine only one of them. At idle, its fluctuation will be 0.6-0.9 l / h.

The diagnostic connector is multifunctional. It helps to find a large number of problems and fix them in a timely manner, and this is an important point for the normal operation of the car.
