For the first time russian car industry installed electric power steering on Lada Kalina. At the first stages, it worked extremely unstable, up to a complete shutdown. Later, they tried to eliminate the shortcomings, but the EUR remained a weak link and periodically fails, as evidenced by the exclamation mark on the panel. This is evidenced by the feeling of a heavy steering, and it becomes difficult to turn with one hand.

The principle of operation of the electric booster is to reduce the force that needs to be applied when turning the steering wheel. The Kalina electric power steering control unit uses sensors to calculate the operation of the electric motor at the current speed and torque. Thus, giving a signal about the effort with which you need to help the driver when cornering. After all, it does not work constantly and needs to be adjusted by the block.

Why the Kalina electric amplifier may not work

The main reason lies in the electric power steering. When ignited, the system self-diagnostics occurs and if the mechanism does not pass it, a signal is turned on, signaling a malfunction. The color of the signal indicates the degree of danger. The red light is on, an urgent need to fix the problem. If the color is yellow, the operation of the vehicle is possible, but it is worth taking safety measures. There may be several reasons why the electric power steering on Kalina does not work: malfunction of the speed sensor; malfunction of the torque sensor; speed exceeds 60 km / h; engine speed less than 400 per minute; failure in the control unit; poorly soldered contacts; insufficient voltage. 1 ... The electric power steering on Kalina turns off after 60 km / h. Therefore, consider this point, it is set in system unit and is not a breakdown. The Priora's electric power steering is switched off at a speed of 110 km / h. Also, the EUR does not work on low revs engine. If the value is less than 400 rpm, it is inactive. 2 ... This is programmatically scheduled inactivity. It is needed to give information to the steering wheel at high speed and reduce the wear of the mechanism.

How to understand the blinking indicator where to look for the cause

✔ one long beep and one short - the electric amplifier is operational; ✔ one long and two short - no engine speed signal; ✔ one long and three short - the torque controller is out of order or power is missing; ✔ one long and four short flashes - problems in the operation of the EUR electric motor; ✔ one long and five short - the steering shaft position controller is out of order; ✔ one long and six short - the motor rotor position controller is out of order; ✔ one long and seven short - power supply problems - the voltage is either too high or very low; ✔ one long and eight short - the control module of the electric amplifier is out of order; ✔ one long and nine short - breakdown of the speed controller.

Before removing the amplifier, you must remove all the steering column switches. Remove the steering rack pad and dismantle the devices, remembering to disconnect the connectors from the power supply.

1 ... After removing the switches, you will need to dismantle the lower cross member dashboard... To do this, you need to click on the fasteners with which the connector with the wires is fixed, and then disconnect the wiring from the control module. When these steps are completed, you can disconnect the connector from the switches. The system bracket is secured with nuts, you will need to unscrew them with a wrench. 2 ... Thereafter steering rack you will need to carefully lower it down. To do this, you will need to locate the bolt that holds the gimbal to the booster shaft. This bolt must be unscrewed, but when unscrewing it will be necessary to fix the nut, this will prevent it from turning. When the bolt is removed, the fastener will need to be released, after which intermediate shaft neatly dismantled. 3 ... At this stage, we recommend marking the position of the shaft and gears, for this you can use a marker. This step is very important because it will prevent possible problems with further installation. In the event that the marks on the shafts do not match, this may cause malfunctions in the amplifier. When dismantling, be careful not to damage the wiring, as this will also lead to the inoperability of the EUR. 4 ... When the unit is dismantled, it will need to be disassembled and the faulty elements replaced. Further installation is carried out in the reverse order.

For the first time, the Russian car industry has installed an electric power steering on Kalina. At the first stages, it worked extremely unstable, up to a complete shutdown. Later, they tried to eliminate the shortcomings, but the EUR remained a weak link and periodically fails, as evidenced by the exclamation mark on the panel. This is evidenced by the feeling of a heavy steering wheel, and it becomes difficult to turn with one hand.

The principle of operation of the electric booster is to reduce the force that needs to be applied when turning the steering wheel.

Thus, giving a signal about the effort with which you need to help the driver when cornering. After all, it does not work constantly and needs to be adjusted by the block.

Reasons for disconnection

The main reason lies in the electric power steering. When the system is ignited, a self-diagnosis of the system takes place and if the mechanism does not pass it, a signal is turned on, signaling a malfunction. The color of the signal indicates the degree of danger. The red light is on, an urgent need to fix the problem. With a yellow color, vehicle operation is possible, but it is worth taking safety measures. There may be several reasons why the electric power steering on Kalina does not work:

• malfunction of the speed sensor;
• malfunction of the torque sensor;
• speed exceeds 60 km / h;
• engine speed less than 400 per minute;
• failure in the control unit;
• poorly soldered contacts;
• insufficient voltage.

Software shutdown

1. The electric power steering on Kalina turns off after 60 km / h. Therefore, take into account this point, it is set in the system unit and is not a breakdown. turns off at a speed of 110 km / h.
2. Also, the EUR does not work at low engine speeds. If the value is less than 400 rpm, it is inactive.

This is programmatically scheduled inactivity. It is needed to give information to the steering wheel at high speed and reduce the wear of the mechanism.

Electric booster malfunctions

In the case when it is impossible to immediately check the cause of the failure of the electric power steering on Kalina, it is necessary to remove the fuse from the block. This is necessary to prevent a sudden activation of the mechanism, which leads to emergency situations.

A direct indicator of a malfunction of the speed sensor in the electric power steering of Kalina is an inoperative speedometer, as well as an illuminated exclamation mark on the dashboard. It may not work for several reasons. Check appearance the sensor, if it gets covered with dirt, just clean it. See if the metal shavings are magnetized and remove them too.

If this does not help, then the sensor is probably out of order. These sensors are now inexpensive and can be found in many auto parts stores. We do the same for the torque sensor. But where is the speed sensor? It is usually located in the gearbox housing, see the photo on the left.

Another reason for the malfunction of the Kalina electric power steering is the generator. To operate the control unit, you need a voltage of 13.6 V, if you have less, change the voltage regulator (chocolate bar) on it.

Also, the contacts could simply be disconnected due to poor-quality soldering. You can either disassemble and solder the contacts or give it to the service.

If the matter is in the control unit, it is difficult to solve this problem on your own, it will either be lost in the service, or you will have to buy a new one.

Diagnostic Scanner

In order not to guess about the cause of the malfunction of the electric power steering, you can connect to the diagnostic port. There are two options, either buy a scanner with a monitor, or connect to a laptop via a cable, after downloading the software to the device.

The second option is cheaper and preferable, as it gives complete information about your car. The error codes can be found on the internet.

Fuse box

The weak link of the electric power steering on Kalina is the fuse box, if something does not work, it is worth checking them. To get to them, you need to open the dashboard to the left of the steering wheel. To do this, pull the upper part towards you and the latch will open.

Check if the fuse works, if it fails, replace it. It is very simple to check, see the integrity of the thread inside the fuse. Changing the 50 amp relay to 30 amp will also help.

Outcome

In newer versions of Kalina, electric amplifiers from Hyundai are installed, which has a positive effect on its reliability. However, there are thousands of cars left with the domestic version, which crashes and breaks down from time to time. Now it will be easier for you to repair the electric power steering on Kalina with your own hands. The main thing to remember is that not every disconnection of the amplifier is a breakdown. And you can find the problem yourself and fix it, but somewhere you have to go to the service.

The purpose of the EUR, as you know, is to provide more comfortable control vehicle... Not so long ago cars domestic production began to be equipped with this type of power steering. What is an electric power steering on the Lada Kalina car, what malfunctions are typical for it and how to replace the unit, read below.

Components of the electric power steering and how it works

On a Lada Kalina car, the electric power steering is a special unit that connects to the steering system and allows for a soft and smooth operation of the steering wheel. Due to the fact that the car has an installed electric amplifier, the traction when turning the steering wheel will be of higher quality, respectively, the driver will need to apply 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;
• gear device;
• the system is also equipped with three controllers - torque, speed, and crankshaft rotation.

The Kalina 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 a simpler control of the vehicle. To control the functioning of the node, it is used on-board computer... 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 over 60 km / h.

In accordance with the connection diagram, such restrictions allow providing the most optimal properties and enable the driver to drive Kalina in the interval considered the most difficult. In addition, such features were implemented by the manufacturer for safety reasons. After all, when driving on high speed the operation of the electric power steering rack is more dangerous. As we already reported, using this node does steering wheel more sensitive, accordingly, 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 driver's overall movement in the car safer.

EUR malfunctions and subsequent diagnostics of the device

As mentioned above, the installation of an electric power steering on Kalina implies the use of a device that is quite simple in design. Accordingly, the repair of the unit and the identification of malfunctions in general is not a particularly difficult procedure. But it should be noted that the very scheme of 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 winter time year, the node will be affected by various temperatures, in particular, their difference.

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

As a rule, failure of the mechanism is facilitated by:

• 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 speed limit of the unit has been exceeded.

At the bottom right there 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 unit and the analysis of the health of all systems. If any of the components does not transmit the corresponding signal, the control unit automatically adds it to the list of inoperative devices. The 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 instruction manual, the manufacturer claims that the problem of the unit malfunction should be resolved as soon as possible. Therefore, the car owner needs to move at a reduced speed to the nearest repair, maintenance and repair station. But this is all - official data, in fact, the situation is 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 operation of the unit. We can talk about both malfunctions in the operation of power circuits, and a breakdown of one of the controllers. As practice shows, in most cases, the appearance of a light bulb on the dashboard 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 is too low. Malfunctions of this kind usually appear quite often and, as a rule, they need to be resolved really immediately. Otherwise, if you ignore the problem, it can lead to sad consequences. To quickly solve the problem, you first need to dismantle the fuse located to the left of the steering wheel. Thanks to this, you can get to the nearest service station for repairs.

VAZ employees claim that the EUR cannot be repaired. If it breaks down, replace it!

Replacing the electric power steering

The procedure for replacing a unit in a Lada Kalina car should be carried out exclusively by experienced specialists. In case if warranty period your transport has not expired, then of course, to fix the problem you need to contact official dealer... If the car's warranty no longer applies, and, as you know, the cost of repairs can be quite high, you can try to solve the problem by replacing the unit. But before proceeding to its elimination, it is necessary to take into account that the replacement procedure itself is not particularly simple. So if you don't have the technical knowledge, experience and skills to accomplish this task, then it's best not to even try to complete 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 unit repair. 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 node connection diagram. To dismantle the system, you will have to partially disassemble the center console, namely the panel mounted under the steering wheel. You will need to disconnect all wires that go to the node.

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

Sorry, there are currently no polls available.

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

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

The electric power steering in Lada Kalina is designed to provide increased comfort while driving. The car itself is on domestic market is present 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 the background of competitors in the class. In this article, we will talk about the malfunction 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 gear. It allows the driver to turn the steering wheel effortlessly, and also provides a soft and smooth operation of the moving parts of the steering system.

Structurally this mechanism cannot be classified as complex nodes. The electric power steering has the following parts:

• electric motor;
• reducer 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 functioning of this amplifier and controls its operation, but malfunctions occur and many car owners are very interested in how to eliminate them. The mechanism is switched on at a motor speed of 400 rpm. When the speed indicator exceeds 60 km per hour, the electric amplifier stops functioning. This is done for the sake of safety, because at high speeds the driver must have a confident feedback on the steering wheel, which the "light" steering wheel cannot provide. With an increase in speed, a gradual decrease in the magnitude of the effort 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 out it, there are different malfunctions and methods of elimination are often complex. An important "aggravating" circumstance is not the best location of the mechanism. The manufacturer placed this module directly under the radiator of the interior heating circuit LADA Kalina.

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

• the speed sensor "does not respond" and does not send signals to the ECU;
• the on-board network "suffers" from low voltage;
• the maximum speed has exceeded the permissible limit;
• the control module has become unusable.

We will discuss the indicated malfunctions and remedies further. When the ignition is turned on, the computer independently performs diagnostics of the amplifier system for possible failures and malfunctions. If there is no signal from any of the sensors, then the on-board controller automatically identifies this sensor as faulty, about which the corresponding lamp immediately lights up on the display on the front panel of the passenger compartment. This indicator looks like a rudder with an exclamation mark and is highlighted in orange.

The instructions supplied by the factory to the LADA Kalina car suggest urgent repairs if a malfunction is detected in the electric power steering mechanism, 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 illuminated on the tidy may not imply 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 in any way affect the functionality of the node, and control control remains active.

If the steering wheel has lost sensitivity after illuminating the indicated symbol, then a malfunction of this kind is considered quite dangerous, since it creates obstacles to 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 intervention. Ignoring this state of affairs can have dire consequences for car LADA Kalina. In order to promptly respond to the problem that has arisen, we quickly remove the fuse located in the panel block to the left of the steering wheel. This measure prevents further damage to the electrical amplification system, since it completely deactivates it. You can go to the place of repair, however, you will need to apply more force to the steering wheel, because the amplifier is no longer 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 indicated two methods of eliminating the amplifier malfunction that has appeared. Then the only solution would be to replace the broken mechanism with your own hands.

Let's make a reservation right away that the replacement process, if the EUR does not work, is characterized by sufficient complexity. For its successful implementation, experience and possession of special tool... Unqualified replacement actions can aggravate the scale of the breakdown, which will entail a significant waste of funds on more expensive repairs under service conditions.

Before the direct 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 unit, which will avoid damage to the electrical components of the mechanism.

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

A common malfunction is the occurrence of a knock, which is clearly heard to the driver from under the panel, or the amplifier is turned off. This phenomenon can be accompanied by a characteristic squeak that occurs during rotational actions with the steering wheel of LADA Kalina. 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 Lada Kalina seat, you need to be careful and patient. All cable connectors must be firmly seated and the device secured firmly. Only then can you proceed to reassembling the previously dismantled front panel components.

The electric power steering is a device designed to provide a more comfortable driving experience. Not so long ago, domestically produced cars began to be equipped with amplifiers. EUR in the car Lada Kalina - what are the malfunctions for him, which are and are most used effective ways elimination? Read about it below.

Causes of EUR breakdown

One of the main reasons why the electric power steering on Kalina can be turned off is the breakdown of the device itself. When the ignition is turned on, the system automatically performs diagnostics, which subsequently does not pass. As a result, the electric power steering does not work due to its own shutdown, which undoubtedly negatively affects the comfort when driving.

Repairing an electric power steering can be quite expensive, so if Kalina is still under warranty, it makes sense to have your ESD repaired by a dealer. In the event that the system has completely failed, you must first turn off the power. In this case, the engine torque will be perceived by the steering element (rack) bypassing the amplifier.

Another reason why the electric booster does not work is the failure of the speed sensor, it is he who is responsible for the operation of the system in various driving modes. The EUR works at full power only when driving at minimum speed. When the transport accelerates, the force that the system creates on the rail is reduced, and this is what the speed controller is responsible for. Do-it-yourself EUR repair implies self-replacement sensor, the cost of such an element is not high today.

If the speed sensor, directly connected to the speedometer, breaks down, then incorrect data is sent to the unit that controls the EUR. The system automatically turns off, at this moment a diode indicator appears on the control panel, which informs the driver about a device malfunction. In order not to face the need to repair the amplifier, it is enough to diagnose with a paper clip in time. Thanks to diagnostics, the motorist will be able to find out about all the problems that are present in various mechanisms and transport units.

Let's summarize this point - for what reasons the electric amplifier refuses to work:

1. There is no signal from the speed sensor. The problem may lie both in the failure of the regulator and in wiring faults.
2. Highly low level voltage in the car wiring. It is necessary to measure the voltage and solve the problem.
3. The permissible motor speed has been exceeded.
4. The control unit is out of order. Repair will help to solve the problem, but usually, if a breakdown occurs, the unit has to be changed.

Dismantling the electric booster

1. If you decide to repair the electric power steering, then first of all it is necessary to dismantle the steering column switches. Further, it is necessary to disconnect all pads with wires from the control panel - if necessary, for this you need to unscrew three self-tapping screws. A Phillips screwdriver is used for this.
2. After completing these steps, you can remove the control panel lower cross member. To do this, press down on the clips that secure the wiring block, then disconnect them from the system control unit. Only after these actions can you disconnect the block from the switches themselves.
3. The bracket itself is fixed with several nuts, they are unscrewed.
4. The entire steering column must be carefully lowered. It is required to find a screw that fixes the cardan to the shaft of the unit. This screw is unscrewed, while you need to hold the nut to prevent it from turning. After dismantling the screw, the terminal retainer must be pushed apart, then the intermediate shaft is carefully removed. To avoid problems in installation, the location of the shaft, as well as the gears, must be marked with a marker. If the marks on the shafts are not aligned, this will lead to problems in the operation of the system. Do not damage the wiring when removing the electric amplifier.
5. As for the installation, the procedure is carried out in the reverse order (the author of the video is Murzik Bely).

EUR error on the dashboard

If an electric power steering error appears on the instrument panel, this may indicate a system breakdown or its incorrect operation. In this case, the electric amplifier can be fully working. The error appearing on the dashboard is on yellow... This indicates that it is possible to use the machine with, but certain safety measures will need to be observed.

If the device shuts down completely, more effort will be required to operate the machine. To turn off the EUR, it is enough to remove the fuse responsible for its operation. If you notice that the system is not working correctly, then it is better to dismantle the fuse and solve the problem.

If you notice that the indicator light on the control panel lights up only when the ignition is turned on, and after starting the engine it goes out, then you should not worry. When the ignition is activated, the system diagnoses all components and mechanisms, so the appearance of the indicator is normal. But if the lamp stays on even after starting the engine, then this indicates a problem.
