Today, all the owners of Lada Kalina are interested in the question: why does the electric power steering on Kalina not work? After all, this car began to be produced back in November 2004, with electric power steering as standard. A ten-year anniversary has passed, but according to motorists, this problem still exists.

The electric booster consists of an electric motor, a force transmission mechanism and an electronic control system. The operation of the electric booster is controlled by an electronic unit with three special sensors that must quickly determine the speed of the car, engine speed and the necessary effort to turn the front wheels.

During the start of the engine with a starter, the electric power steering (EUR) does not work. It turns on only from the moment of reaching 400 rpm crankshaft and stops working when the car accelerates over 60 km. at one o'clock.

Symptoms

Why the electric power steering does not work on Kalina is impossible to figure out right away. However, in most cases of malfunction (EUR), a light depicting a steering wheel with an exclamation mark should light up on the instrument panel. After that, the specialists of the VAZ automobile plant recommend moving to a car service at low speed.

Why at low speed? Because the first years of production (EUR) by the Makhachkala plant, he had the peculiarity of turning the driving wheels of the car as much as possible to the left or right and independently fixing himself in this position.

No need to talk about the consequences.. But even if the emergency light on the dashboard does not light up, the steering wheel may begin to crackle and beat with large tremors, or you will feel that (EUR) at times turns off and on on its own, for no apparent reason at all.

The electric motor and mechanical part (EUR) rarely cause complaints, but the electrics and electronics require a detailed study of breakdowns.

Debriefing

Electronic control unit (ECU) for electric power steering, fixed in an unfortunate place, under the radiator of the heater stove. Any leakage in this part causes wetness (ECU), after which you will feel that the power steering is not working and the steering wheel has become heavy.

If while driving you notice that the tachometer or speedometer needle is at zero and does not move, be sure that (EUR) your car is not working. This is because these devices and (EUR) are activated from the same sensors.

Most often on Kalina,. Buying a new sensor and replacing it solves this problem. There are very frequent cases when replacing sensors does not help, (EUR) still does not work. Start methodically probing the entire circuit of wires related to the system (EUR).

And the poor quality of production connecting plugs and blocks, independently break the electrical circuits at the most inopportune moment.

Power steering Kalina, misbehaves with on-board voltage fluctuations. If, instead of 15 Volts, it gives out less than 30, then the electronic control unit, power steering may also refuse to work.

The purpose of the EUR, as you know, is to provide a more comfortable driving experience. Relatively not so long ago, domestic-made cars began to be equipped with this type of power steering. What is an electric power steering on a Lada Kalina car, what malfunctions are typical for it and how to replace the assembly, read below.

Components of the electric power steering and the principle of its operation

On a Lada Kalina car, the electric power steering is a special unit that connects to the steering system and allows for soft and smooth operation of the steering wheel. Due to the fact that the car has an installed electric booster, traction when turning the steering wheel will be of better quality, respectively, the driver will need to exert less effort.

As for the design of the device itself, according to the standard, it consists of:

• first of all, the electric power steering circuit includes an electric motor;
• an equally important component is the control unit;
• reduction device;
• the system is also equipped with three controllers - torque, speed, and rotation of the crankshaft.

Kalina's electric power steering system, as you can see, is generally simple in design. Despite its simplicity, even such a device makes it possible to obtain all the necessary data and provide easier vehicle control. An on-board computer is used to control the functioning of the node. It should be noted that the node itself does not always function. It comes into operation when the number of revolutions reaches 400 per minute and turns off if the vehicle speed is more than 60 km / h.

In accordance with the connection scheme, such restrictions allow for the most optimal properties and enable the driver to drive Kalina in the interval considered the most difficult. In addition, such features were introduced by the manufacturer for security reasons. After all, when driving at high speed, the operation of the steering rack with electric power is more dangerous. As we have already reported, the use of this node makes the steering wheel more sensitive, respectively, this can lead to certain risks when driving at high speed. So when driving at a speed of more than 60 km / h, the device turns off automatically, making the overall movement of the driver in the car safer.

EUR malfunctions and subsequent device diagnostics

As mentioned above, installing an electric power steering on Kalina involves the use of a device that is quite simple in design. Accordingly, the repair of the unit and troubleshooting in general is not a particularly complicated procedure. But it should be noted that the scheme for connecting the EUR, namely the location of the node, was not chosen by the manufacturer very well. This is because the installation of the EUR is carried out under the heater radiator. So when using the car in the winter season, the node will be affected by various temperatures, in particular, their difference.

This is what largely affects the breakdown of the node and, as practice shows, in fact this happens quite often. The failure of the electric power steering is associated with the appearance of problems in the operation of the vehicle control and the appearance of various malfunctions.

As a rule, the failure of the mechanism contributes to:

• lack of impulse from the speed controller;
• failure of the system control unit;
• too low voltage in the on-board network of the vehicle;
• the permissible threshold of the unit's revolutions has been exceeded.

At the bottom right is an indicator in the form of a steering wheel with an exclamation mark - it indicates a malfunction of the EUR

These factors, as practice shows, contribute to the breakdown of the mechanism. As for diagnostics, it is carried out by the Kalina control unit independently during the launch of the node and analysis of the health of all systems. If any of the components does not transmit the corresponding signal, the control unit automatically enters it into the list of non-working devices. Relevant information can be seen on the control panel. In particular, if we are talking about the failure of the EUR, then an orange indicator in the form of a steering wheel with an exclamation mark will appear on the tidy.

In accordance with the service manual, the manufacturer claims that the problem of a node malfunction should be resolved in the near future. Therefore, the car owner needs to drive at a reduced speed to the nearest maintenance and repair repair station. But this is all - official data, in fact, things are somewhat different.

As a rule, the appearance of an indicator on the control panel does not imply the need for repair, usually its appearance indicates a malfunction in the unit. We can talk about both malfunctions in the operation of the power circuits, and the breakdown of one of the controllers. As practice shows, in most cases, the appearance of a light bulb on the shield does not affect the functioning of the unit as a whole (the author of the video is the CompsMaster channel).

In fact, a breakdown is considered a problem, in which the steering sensitivity will be too low. This kind of malfunction usually occurs quite often and, as a rule, they need to be addressed really immediately. Otherwise, if the problem is ignored, it can lead to sad consequences. To quickly solve the problem, first of all, it is necessary to dismantle the fuse located to the left of the steering wheel. Thanks to this, you will be able to get to the nearest service station for repairs.

VAZ employees claim that the EUR is beyond repair. If it breaks, it must be replaced!

Electric power steering replacement

The procedure for replacing a node in a Lada Kalina car should be carried out exclusively by experienced specialists. In the event that the warranty period for your vehicle has not expired, then, of course, to fix the problem, you must contact an authorized dealer. If the warranty for the car is no longer covered, and, as you know, the cost of repairs can be quite high, you can try to solve the problem by replacing the assembly. But before proceeding to its elimination, it must be taken into account that the replacement procedure itself is not very simple. So if you don't have the technical knowledge, experience, and skills to do this task, it's best not to even attempt it.

Always remember that incorrect actions during the repair can lead not only to a complete failure of the system, but also to a rather complicated and expensive repair of the unit. So the installation of an electric amplifier should be carried out only after you have studied all the components, details and features of the system. In this case, first of all, you need to familiarize yourself with the connection diagram of the node. To dismantle the system, you will have to partially disassemble the center console, namely the panel installed under the steering wheel. You will need to disconnect all the wires that go to the node.

As practice shows, the installation of a new node in most cases may not be required, since usually the problem can be solved by taking preventive measures. In fact, one of the most common problems in the operation of the knot is knocking. This knock usually occurs when turning the steering wheel and in most cases it is accompanied by a squeak. To solve the problem of such a plan, it will only be enough to lubricate the assembly. If this does not help, then further you will need to make a more thorough diagnosis or replace the node.

Sorry, there are currently no surveys available.

Video "Instructions for replacing the electric power steering with Kalina"

A detailed step-by-step video instruction regarding the replacement of a node in a Lada Kalina car is shown in the video below (the author of the video is Sergey Tsapyuk's channel).

The electric power steering in Lada Kalina is designed to provide increased comfort while driving. The car itself has been present on the domestic market recently, but managed to acquire significant popularity. The car is quite practical and convenient, which allows it to have a wide army of fans. The cost of the model is low, which ensures favorable positioning in the market against rivals in the class. In this article, we will talk about the problem and how to fix them.

What does Kalina's power steering consist of?

This unit is an independent device included in the Lada Kalina steering mechanism. It allows the driver to turn the steering wheel without much effort, and also ensures the softness and smoothness of the moving parts of the steering system.

Structurally, this mechanism cannot be attributed to complex nodes. The electric power steering has the following parts:

• electric motor;
• gearbox block;
• control module;
• sensors that monitor the moment, speed and number of revolutions made by the crankshaft.

The on-board controller Lada Kalina continuously monitors the operation of this amplifier and controls its operation, but malfunctions occur and many car owners are very interested in how to fix them. The mechanism is switched on at engine speeds of 400 rpm. When the speed indicator exceeds 60 km per hour, the electric amplifier ceases to function. This is done for the sake of safety, because at high speeds the driver must have confident feedback on the steering wheel, which the “light” steering wheel is not able to provide. With an increase in speed, a gradual decrease in the magnitude of the force in the mechanism is observed.

EUR malfunctions and their diagnostics

Despite the simplicity of the design of the unit we are considering, if there is a need for repair, it is difficult to carry it out, there are different malfunctions and the methods of elimination are often complex. An important "aggravating" circumstance is not the best location for the mechanism. The manufacturer placed this module directly under the radiator of the LADA Kalina saloon heating circuit.

Operation in cold weather has a temperature effect on the electric power steering. Over time, this factor causes malfunctions in the amplifier. This phenomenon is very common for Lada Kalina. If the unit fails, the driver immediately feels the weight of driving at low speeds. The most common factors leading to malfunctions of an electric amplifier can be grouped into the following areas:

• the speed sensor "does not respond" and does not send signals to the computer;
• the on-board network “suffers” with low voltage;
• the maximum speed has exceeded the allowable limit;
• the control module has failed.

The indicated malfunctions and solutions will be discussed below. When the ignition is turned on, the ECU independently performs diagnostics of the amplifier system for possible failures and malfunctions. If there is no signal from any of the sensors, the on-board controller automatically identifies this sensor as faulty, which is indicated by the corresponding lamp on the display of the front panel of the passenger compartment. This indicator looks like a steering wheel with an exclamation mark and is highlighted in orange.

The instructions attached by the factory to the LADA Kalina car require immediate repair if a malfunction occurs in the mechanism of the electric reinforcement of the steering unit, especially when the amplifier is turned off. In such a situation, the driver should go to the service at low speed. Practice shows that this development of events does not always take place. An orange symbol on the dash may not indicate the need for repair procedures. It indicates the presence of a problem in one of the structural components of the system. Sometimes failures can occur in the supply circuit or one of the sensors is out of order. These situations do not affect the functionality of the node in any way, and management control remains active.

If the steering wheel, after highlighting the indicated symbol, has lost sensitivity, then a malfunction of this kind is considered quite dangerous, since it interferes with the normal functioning of the mechanism as a whole, it is also bad when the amplifier is turned off. Such problems often arise and really require urgent attention. Ignoring this state of affairs can be associated with sad consequences for the LADA Kalina car. In order to quickly respond to the problem that has arisen, we quickly remove the fuse located in the panel block on the left side of the steering wheel. This measure eliminates causing further harm to the electrical amplification system, since it completely deactivates it. You can go to the repair site, but you will need to apply more effort to the steering wheel, because the amplifier is now not functioning.

About the qualified replacement of the electric amplifier

If there is a need to replace the mechanism when the EUR does not work, we recommend contacting experienced craftsmen. When the car is under warranty, the most rational measure would be to contact the dealer network in order to eliminate the problem.

There are situations that do not allow resorting to the above two methods for eliminating an amplifier malfunction that has appeared. Then the only solution would be to replace the worn-out mechanism with your own hands.

We will immediately make a reservation that the replacement process, if the EUR does not work, is characterized by sufficient complexity. For its successful implementation, experience and the possession of a special tool are required. Unqualified replacement actions can aggravate the scale of the breakdown, which will entail a significant waste of funds for more expensive repairs in the service environment.

Before the immediate replacement procedure, we recommend that you carefully study the entire list of features and actions if the EUR does not work. Here you will need to delve into the connection diagram of the node, which will avoid damage to the electrical components of the mechanism.

To remove the amplifier, partial disassembly of the front panel Lada Kalina is necessary. After that, the device itself must be disconnected from the entire list of supply wires. Sometimes owners repair the electric power steering, avoiding the need to replace with a new unit. As a rule, after a complex of restoration works, regular devices work no worse than their new counterparts.

A common malfunction is the occurrence of a knock that is clearly heard by the driver from under the panel or the amplifier turns off. Such a phenomenon may be accompanied by a characteristic creak that occurs during the implementation of rotational actions with the LADA Kalina steering wheel. Usually this situation is solved by using a special lubricant. If such an action does not bring the expected result, then a more detailed diagnosis of the amplification mechanism will be required.

To install the electric power steering in the seat of the Lada Kalina, you will need to stock up on care and patience. All cable connectors must be firmly seated, and the device itself must be securely fastened. Only then can you proceed to the reassembly of the previously dismantled front panel components.

Often refuses to work both on new Lada Kalina cars and on cars with high mileage. If there is a problem on the dashboard, a yellow error in the form of a steering wheel with an exclamation mark lights up. It indicates a malfunction or failure of the electric power steering. It should be borne in mind that the yellow color indicates that the problem is not critical and you can drive a car without the help of an electric booster. In case of its failure, it is better to pull out the EUR fuse, which is located to the left of the steering wheel.

Repair of the electric power steering viburnum must be carried out for various reasons.

The main causes of a malfunction of the electric power steering:

• Malfunctions in the electric power steering itself. When the ignition is turned on, the EUR does not pass self-control and turns itself off so as not to interfere with the driver and not cause emergency situations on the road. In such a situation, repairs will be quite expensive and with a valid warranty it is better to use it.
• Malfunctions of the speed sensor, which is a fairly common cause. In such a situation, repairs will be inexpensive and you can do it yourself. The fact is that the EUR does not work with a constant force that is applied to the steering rack. It only works at full power when the car is running at low speed or standing still. When accelerating the car, the electric power steering reduces the effort on the steering rack, thereby the driver can better control the course of the car. Thus, the higher the speed, the less the EUR works, helping these drivers. The EUR reads the vehicle speed from the speedometer, which receives data from the speed sensor. Sometimes the sensor breaks down and gives incorrect information. As a result, the EUR turns off, because it does not know the speed of the car. After that, the EUR error lights up on the dashboard. In this case, the repair of the viburnum electric power steering is carried out by replacing the sensor.

To avoid premature repair of the viburnum electric power steering, timely diagnostics should be carried out to identify problems in its functioning and evaluate its performance.
