DIY electric power steering repair

In detail: do-it-yourself repair of an electric power steering viburnum from a real master for the site my.housecope.com.

Electric power steering is installed on Lada Kalina cars. Its design is very simple, it consists of one unit, so even a "standard" ESD machine can be installed without any problems. It contains no liquid, which means it is easy to maintain. But it is worth paying attention to the experience of foreign manufacturers who try not to install EUR in their cars. This mechanism has a peculiarity: it can operate at both low and high speed. The second option is undesirable, since the slightest movement by the steering wheel can cause the car to be carried into a ditch or to the side of the road.

The Lada electric power steering circuit provides for the operation of the mechanism at different speeds, and when driving, it either functions or turns off. The malfunction lies in the fact that the EUR stops in some kind of state. It is forbidden to use the car until the breakdown is repaired. A yellow lamp on the dashboard will alert you of the problem. It depicts an exclamation mark and a steering wheel. If the malfunction lies in the EUR unit, and there is no way to eliminate it, you should remove the fuse, which is responsible for the operation of the electric amplifier. It should be borne in mind that EMUR can refuse not only on old, but also on new Kalina, which did not have time to go through the running-in.

Here is this useful auto node

The main cause of the malfunction lies directly in the electric amplifier. When the ignition is turned on, a self-diagnosis of the system occurs, which the mechanism does not pass. As a result, the EUR is simply turned off, and this affects the convenience of driving. Repairing the device can cost a pretty penny, so if the car is still under warranty, it is better to have it serviced by a dealer. If the amplifier has completely failed, turn off the power. In this case, the steering rack will take the torque bypassing the electromechanical amplifier.

Another common malfunction is the breakdown of the speed sensor. It is this sensor that is responsible for the operation of the electric booster at different speeds. The EUR works at full power only when driving at a very low speed. When accelerating, there is a decrease in the force created by the amplifier on the rail. The speed sensor is responsible for such an operation algorithm. It is not difficult to replace it yourself, so the repair will cost a small amount.

If the speed is higher, then EMUR works less, since it is not needed. For this reason, on Kalina with electric power steering, control at high speed is the same as in the "standard" configuration model without this device. If the speed sensor connected to the speedometer fails, the electric power steering control unit receives incorrect data. As a result, the EUR turns off, and the driver sees a yellow indicator on the dashboard, notifying of an error in the electric booster.

But unexpected repairs and system failures can be avoided. It is enough to undergo diagnostics in a timely manner. It will show all the problems that are present in the components of the car. This is the easiest and surest way to get rid of problems. If the EUR breaks down, you will have to remove it and carry out repairs or replacement. It is dismantled with a steering column. This requires a 13 wrench, Phillips and flathead screwdrivers.

Before starting the dismantling, it is necessary to set the wheels in a straight position and remove the negative terminal from the battery.

The first step is to get rid of the steering column switches. After that, disconnect all pads with wires from the dashboard.If it is necessary to dismantle the ignition lock, unscrew the 3 self-tapping screws with a Phillips screwdriver. Next, the lower cross member of the dashboard is removed. After that, press the clips of the wiring harness blocks and disconnect them from the EMUR control unit. And only now you can disconnect the block directly from the steering column switches.

How is the unit located in the car

The bracket is secured with 4 nuts that need to be unscrewed. The entire steering column is then gently lowered to the floor. Find the bolt that secures the cardan to the steering shaft. Unscrew it with a 13 key, while keeping the nut from turning in the same way. The bolt is removed and the terminal connection is opened with a strong flat-blade screwdriver. The intermediate shaft is carefully removed. It is recommended to mark with a marker the location of the shafts and gears relative to each other. Further, the necessary repairs to the electric power steering are carried out and the assembly of the unit begins.

Be careful not to damage the wiring during dismantling. Mark the location of the shafts and gears as precisely as possible so that later on there will be no inconvenience when turning the steering wheel. The installation of the EUR is carried out using the same tools, only in the reverse order. The most important thing is to match all the marks on the shafts. The help of a partner will not be superfluous.

Place the lower joint on the pinion shaft in advance. First, connect the intermediate cardan directly to the steering shaft, then use a 13 socket wrench to unscrew the nut designed to tighten the intermediate shaft. Remove the bolt and carefully disconnect the upper hinge from the lower one. The first step is to install the lower hinge, after which the shaft is rotated until the hole in the upper hinge is located for the bolt in the lower part of the shaft. Now it remains only to connect the hinges and tighten with a bolt. Then connect the connectors and fit the cladding panels.

The on-board computer will signal a malfunction of the EUR

Owners of a Kalina car with an installed electric power steering enjoy pleasant and convenient control, but run the risk of encountering a problem - the "EUR error" lamp lit up. The reason for this can be either a complete system failure or its incorrect operation. It is worth noting that the sensor glows yellow, not red. This means that you can operate a car without a working electric power steering Lada Kalina, observing some precautions.

More effort will have to be applied to the steering wheel if you turn off the EMUR completely. This can be done quite simply by removing the fuse responsible for powering the control unit. If the power steering does not work or some strange phenomena are observed in its behavior, it is better to remove the fuse and go through a full diagnosis of the car's systems, which will show the cause of the breakdown. Driving without an electric booster can be tricky. Out of habit, the steering wheel seems too tight, but in fact it is the same as on the Kalina of the "standard" configuration.

There are two reasons for EMUR failure: a malfunction of the speed sensor or a breakdown in the control unit. The first problem is solved very quickly, it can be done even in a garage. In the second case, you will have to remove the control unit and contact an experienced electrician to install a new one. If the warranty is valid, it is necessary to show the car to specialists in a car service.

If you still want to remove and install the control unit yourself, you only need a Phillips screwdriver from the tools. First, all plastic panels under the steering wheel are dismantled to facilitate access to the unit. And remember to disconnect the battery to avoid wiring problems. The plastic trim, which is located at the bottom of the panel, is secured with three screws. They must be unscrewed and the cover removed.

The view of the control unit itself opens after dismantling the cover.All plugs must be disconnected from the EMUR control unit. The block itself is attached with two bolts. Unscrew them and carefully pull the box down to avoid damaging anything. Remember that the block is still attached to the record. The box should be just above the pedals. Only after that you need to unscrew the three bolts that will pull the control unit to the plate. Now all that remains is to screw the new control unit onto the plate and carefully install everything in the reverse order. Fasten the box with two bolts, then connect all the plugs, after which you can start assembling the cladding panels.

Electric power steering on Kalina serves to increase driver comfort. With it, you can easily turn the steering wheel with one finger, even in a stationary car. It is convenient and practical, as parking with such a system turns out to be much easier and safer. The electric booster device includes:

brushless electric motor;
reducer;
Control block.

The electric motor is under the steering wheel. A worm is installed on its shaft, which meshes with a plastic gear. The electronic unit controls the operation of the entire system, using the data that give out:

torque sensor;
speed sensor;
crankshaft speed sensor.

After collecting the data, the control unit regulates the supply voltage that is supplied to the electric motor. The lower the vehicle speed, the more voltage is supplied to the electric motor.

The lamp indicating a malfunction of the electric booster on Kalina lights up as soon as the ignition is turned on. After starting the engine, it goes out. This is a normal operation of the system, and in the event of a breakdown, even after starting the motor, the lamp continues to burn.

Reasons for the failure of the electric amplifier.

There is no signal from the speed sensor.
Critically low voltage in the on-board network.
The permissible value of the engine speed has been exceeded.
Control unit malfunction.

To repair the EUR, the steering wheel and part of the torpedo are dismantled

In the first three cases, the failure of the EUR on Kalina is eliminated quite simply. Either tighten the alternator belt or apply less force when pressing on the accelerator pedal.

A malfunction of the control unit is a reason to visit a diagnostician, who will conduct a high-quality inspection and identify a breakdown. Moreover, some problems can be eliminated by an electrician, and some are fatal, and only replacing the entire unit will help.

Electric power steering Kalina greatly simplifies the movement of the car and makes it enjoyable to operate. Lada Kalina not so long ago appeared on the modern car market, but has already become widely known and gained immense popularity among the population. This fact is due to the practicality of this machine and its convenience. In addition, the cost of such a brand favorably distinguishes it from the background of other cars. This effect was achieved due to the presence of many additional parts included in the design of the machine, which not only simplify the use of the machine, but also make this process more comfortable.

The electric power steering on Kalina is a special device that is connected to the steering wheel systems and ensures its smooth and soft operation. This solution allows you to rotate the steering wheel without much effort. The very design of the EUR is quite simple and consists of only a few parts:

electric motor;
reducer;
Control block;
torque sensor;
speed sensor;
crankshaft speed sensor.

EUR is a fairly simple system. But even such a design of it allows the device to receive all the necessary information to ensure the movement of the machine. The control over the operation of the device is carried out directly by the on-board computer, which is included in the factory configuration of Lada Kalina.The electric power steering turns on when the speed is 400 rpm, and turns off when it exceeds 60 km / h. Such frames provide the best performance and allow you to drive the car in the most difficult period. In addition, such indicators are determined by the manufacturer based on safety considerations, since the operation of the ESD at high speeds is associated with a certain risk.

As mentioned above, connecting the device makes the steering wheel extremely sensitive, which can be a big problem at high speeds. That is why when 60 km / h is exceeded, the amplifier is turned off by the system, making it more static and safe.The design of the EUR is quite simple, which makes it quite easy to repair. But its location was not chosen by the manufacturer very well. The electric amplifier module is fixed directly under the stove radiator. Therefore, during the operation of the device, especially in winter, it is periodically exposed to temperature effects. Which is one of the reasons for its failure. Unfortunately, such a development of events is observed quite often. Failure to operate the EUR is associated with the emergence of some difficulties in driving and the appearance of certain malfunctions. In most cases, the following factors are responsible for malfunctions:

lack of speed sensor signal;

low voltage in the power supply network of the car;

the maximum value of the system revolutions has been exceeded;

the control unit is defective.

All these factors lead to the failure of the device. Diagnostics of a similar condition is carried out by the car independently as a result of starting the system and turning on the on-board computer, which checks the health of all systems. In the absence of a signal from any element, the computer automatically considers it to be faulty, which displays the appropriate information on the dashboard. If the electric power steering does not work, then a special orange light in the shape of a steering wheel with an exclamation mark lights up on the screen. The manufacturer's instruction states that the failure of the EUR provides for urgent repair. For this, the driver must move at low speed to the service station to carry out the appropriate action. In practice, the situation is slightly different. Image - DIY electric power steering repair

In most cases, an illuminated dashboard light does not at all imply a repair. It shows the presence of any malfunction in the EUR assemblies. This can be either a malfunction in the power circuits, which implies a device connection diagram, or a failure of one of the sensors. At the same time, this fact has absolutely no effect on the control over the control of the car. The real problem is problems that affect the sensitivity of the steering wheel and prevent it from working properly. These problems arise quite often and require an immediate response, since ignoring them can lead to dire consequences. To quickly neutralize such a problem, remove the fuse, which is located on the left side of the steering wheel. This step will allow you to get to the repair site without interference, although driving will become a little more difficult.

A defective EUR will not affect the steering wheel and interfere with the control of the machine.

Replacing the electric power steering should be carried out only by experienced craftsmen, and if the warranty period for Lada Kalina has not yet expired, then the best solution would be to contact the dealer network to solve the problem. If the warranty has expired, and it is difficult to collect additional funds for a qualified repair of the device, then the way out of this situation is to install an electric power steering with your own hands. It should be borne in mind that this procedure is rather complicated.Therefore, without some preparation and the presence of technical skills, it is not worth it. Unqualified actions can result not only in a complete system failure, but also in more complex and expensive repairs. Therefore, the installation of the EUR should be done only after studying all the details and features of the car networks. In such a situation, the device connection diagram will become an indispensable assistant and will allow you to perform the necessary actions more clearly.

To remove a faulty electric booster, it is necessary to partially disassemble the panel located under the steering wheel and disconnect all the wires going to the device. The installation of a new electric power steering may not be necessary, since there is a high probability that after carrying out some preventive measures, the old device will work no worse than the new one. One of the most common problems of this type is a knock on the power steering, accompanied by a squeak when the wheel itself is turned. In such a situation, the EUR lubricant can solve the problem. If this step did not help, then the device requires more detailed diagnostics or a complete replacement.The installation of the EUR requires some care. All wires must be connected, the device itself is installed in its proper place, and the steering column is assembled back.Electric power steering is a device designed to provide more comfortable driving. Not so long ago, domestically produced cars began to be equipped with amplifiers. EUR in the car Lada Kalina - what are the types of malfunctions for it, what are the most effective ways of elimination? Read about it below.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. At full power, the EUR functions only when driving at minimum speed. When the transport is accelerated, the force that the system creates on the rail is reduced, and this is what the speed regulator is responsible for. Do-it-yourself repair of the EUR involves the independent replacement of the 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 carry out diagnostics 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:

There is no signal from the speed sensor. The problem can lie both in the failure of the regulator and in wiring faults.

Very low voltage level in the car wiring. It is necessary to measure the voltage and solve the problem.

The permissible motor speed has been exceeded.

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.

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 you need to remove the ignition switch, then for this you need to unscrew three self-tapping screws. A Phillips screwdriver is used for this.

After completing these steps, you can dismantle the lower cross member of the control panel. To do this, press on the clips that secure the wiring block, and then disconnect them from the system control unit. Only after these steps can you disconnect the block from the switches themselves.

The bracket itself is fixed with a few nuts, they are unscrewed.

The entire steering column must be carefully lowered. It is required to find the 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 released, 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. Never damage the wiring when removing the electrical amplifier.

As for the installation, the procedure is carried out in the reverse order (the author of the video is Murzik Bely).

If an error of the electric power steering appears on the instrument panel, then this may indicate a breakdown of the system or its incorrect operation. In this case, the electric amplifier can be fully working. The error appearing on the dashboard is yellow. This indicates that it is possible to use the machine even when the EUR is not working, 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 goes out after starting the engine, 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.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. 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. Image - DIY electric power steering repair

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;
the engine speed is less than 400 per minute;
failure in the control unit;
poorly soldered contacts;
insufficient voltage.

The electric power steering on Kalina turns off after 60 km / h. Therefore, consider this point, it is set in the system unit and is not a breakdown. Electric power steering "Priora" is disabled at a speed of 110 km / h.
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.

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 the appearance of the sensor, if it gets covered with dirt, just clean it. See if the metal shavings are magnetized and remove them as well.

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 found 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 send them 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 soldered in the service, or you will have to buy a new one.

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.

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.

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 malfunctions 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 electric power steering is a unit used to provide more comfortable driving. Not so long ago, domestic-made cars began to be equipped with EUR, in particular, in this article we will talk about Ladakh Kalina.What malfunctions of the EUR Kalina can happen and what are the ways of troubleshooting? Look for answers to these and other questions below.

Why does the electric power steering on Lada Kalina not work or turn off, for what reasons does the steering wheel with the EUR knocks, wedges and bites? To repair the system with your own hands, you need to know how diagnostics are carried out and what reasons precede the breakdown. Most often, the failure of the amplifier is due to the breakdown of the unit itself. Malfunctions of such a plan are eliminated by thoroughly checking the system to identify the exact problem.

As practice shows, often the inoperability of the electric booster is associated with a breakdown of the speed controller, since this sensor provides activation and deactivation of the EUR in different driving modes. The amplifier on Kalina works if the car is moving at low speed. When the speed starts to increase, the amplifier is automatically turned off, which allows for safer control of the machine when driving at high revs.

So, briefly about the reasons for the inoperability of the EUR:

The speed controller is out of order or the control unit does not receive a signal from it. In this case, the reason may lie both in the breakdown of the sensor, and in damage to the wiring or poor contact of the controller with the on-board network.
The voltage in the vehicle's electrical system has dropped. The reasons can be different, ranging from a dead battery and an inoperative generator and ending with the use of inappropriate electrical equipment in the car.
The permissible number of revolutions of the crankshaft has been exceeded.
Incorrect operation or failure of the control module. Depending on the reason, the control unit may need to be repaired; more detailed diagnostics must be done.

To check the amplifier in a car, you need to dismantle the plastic trim on the steering column, for this unscrew the bolts securing it from below.

Then you will need to get to the 8-pin plug, its pinout is as follows:

the blue contact is connected to the ignition switch, this is a 12 volt power supply;
the red-brown contact is the tachometer connection cable;
the gray contact goes to the auto speed controller;
white-pink wire - amplifier control indicator;
black and yellow contact is a diagnostic line;
the next contact is empty, the wire is not connected to it;
brown contact is mass;
empty.

More accurate results will be obtained by checking the amplifier using a scanner. But since such equipment can usually only be found at a service station, you can try to check the operation of the system with a paper clip.

To check, you need to do the following:

The ignition is switched off first.
Then, using a paper clip, it is necessary to close the contacts numbered 6 and 7 of this plug, while the plug itself does not need to be dismantled.
Next, the ignition must be turned on.
After completing these steps, the EUR breakdown indicator located in the dashboard will start blinking, by the number of blinks, you can determine the system breakdown (video author - Gosha Vakhromeev).

one long and one short signal - the electric amplifier is in good order;
one long and two short - no engine speed signal;
one long and three short - out of order or no power supply to the torque controller;
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 need to dismantle all the steering column switches. Remove the steering rack pad and dismantle the devices, remembering to disconnect the connectors from the power supply.

How to remove the EUR with your own hands:

The appearance of a knock in the work of the EUR is associated with the need to tighten the steering rack.

How to do it right:

How and with what to lubricate the amplifier?

Litol can be used as a lubricant, the procedure is as follows:

First you need to remove the plastic casing, for this unscrew the bolts that secure it. Use a Phillips screwdriver to unscrew. It is also advisable to dismantle the dashboard lower cross member located under the steering wheel.
Next, unscrew the two bolts that fix the amplifier itself, for this you need a 13 spanner. After that, the column can be released downward.
Unscrew another bolt, after which you can do the lubrication directly.
First, the steering wheel is turned to the left as far as it will go. The lubricant is poured into a 10 cc syringe and sprayed into the resulting hole. You need to throw out all 10 cubes.
Then the steering wheel turns to the right until it stops - the syringe is again directed into the hole, all the lubricant is sprayed out.
After that, the steering wheel should be turned to the middle position and again sprayed with grease into the hole.
Further, the steering wheel must be turned in different directions until it stops several times. The lubrication operation is repeated one more time.
Then all the components are assembled in reverse order.

How to properly repair the electric power steering on a Lada Kalina car and what mistakes cannot be made in this case - detailed instructions are given in the video (video by CompsMaster).

Many owners of Lada Kalina and Lada Granta are familiar with the problem of the appearance of extraneous noise when turning the steering wheel (with short swaying) or when driving on an uneven road. If the car is equipped with a geared electric power steering (EUR) produced in Makhachkala (catalog number 11186-3450008-00), then the reason may be in it. This EUR is not installed on the Lada Priora. It is noteworthy that there is no knock on the EUR (gearless) produced in Kaluga or MONDO. We will tell you how to fix this problem.

The main reason for the appearance of knocking on the electric power steering is backlashthat appears during the operation of the vehicle. If the knocks resemble drum roll, then most likely it is the bearings that are poorly tightened. Most often, the smallest of the three bearings of the electric drive rotor, which is located at the top of the conical part of the EUR housing, strumbles. You just need tighten the adjusting nut (do not overdo it, otherwise the bearing will break).In some versions of the electric power steering, there is no adjusting nut, and if you disassemble the amplifier, you will notice adjusting washers between the bearing and the gear. In this case, the backlash can be reduced by using installation of additional washerschoosing them empirically. It should be borne in mind that the thicker the gasket, the tighter the steering wheel will rotate, and too small a thickness of the washers will cause the EUR to knock.

With such a modification, the electric power steering will have to be removed and disassembled. The most difficult thing will be to divide the electric amplifier into two halves. When reassembling, remember to apply grease... Do not strip the threads during assembly, they are weak.

If there is a metallic knock when you turn the steering wheel all the way in both directions, then most likely you are just bumping into the end of the steering rack. In this case, there is no cause for concern.

In some cases, you cannot do without electric power steering repair, replacement of worn-out parts with new ones.The cardinal way to get rid of knocking is remove the EUR at all, or replace it on gearless.

Not always, a knock when turning the steering wheel can be caused by an electric booster, sometimes extraneous noise occurs due to the steering rack or column.

Electric power steering is a problematic place for Lada Kalina. Surely, this is due to the fact that the domestic auto industry only recently got acquainted with the EUR. "Avtovaz" did not have time to learn how to make good-quality steering systems. So repair of electric power steering on Kalina is still a frequent practice... But it is best for specialists to deal with it.

Amateurishness will be inappropriate here - it can only aggravate the situation. The steering system is an important unit, on the serviceability of which the efficiency of driving and, of course, safety depends.

Repairing the electric power steering on Kalina is a demanding job that requires certain knowledge in the field of EUR. And since the minimum number of motorists possesses such knowledge, then, in case of problems, the drivers go to the service station, which is fundamentally correct.

Despite the fact that the repair of the EUR requires contacting a car service, you can detect the first symptoms of a malfunction yourself.

The viburnum on the front panel has a special yellow indicator, which, in the event of a breakdown of the electric amplifier, lights up and reports an error in the system. If it caught fire, then you have another reason to visit the nearest auto repair shop. But it should be noted right away that the yellow indicator does not indicate a critical malfunction, but only signals the occurrence of a malfunction, which allows you to drive the car, but without the participation of the EUR.

If the electric power steering has completely failed, then it is better to stop immediately and pull out his fuses... In Kalina, they are on the left side of the steering wheel. Theoretically, in case of malfunctions, the EUR should turn off on its own. However, once at a time it is not necessary. Therefore, to be sure, it is still worth taking care of the fuses.

The main problem that causes a breakdown of the electric power steering is a malfunction of the speed sensor.

The EUR installed on Kalina does not work with constant effort applied to the steering rack. The amplifier starts working at full strength only when the car is moving at low speed or arriving at rest. When accelerating, the efforts of the amplifier on the steering rack are reduced. That is, the lower the speed of movement, the more the EUR starts to work.
