How dangerously weird electric power steering is, especially VAZ ones - data from 2022

Electric power steering is designed to make driving life easier. It helps to turn the steering wheel in a parking lot without putting much effort; in modern cars it prevents accidents and makes driving easier. It is more reliable and better than the hydraulic booster, but it still breaks down, although less often. Let's look at the main malfunctions in the operation of the electric amplifier and how they manifest themselves in order to be prepared for repair costs.

Battery problems

Based on this, we can draw the first conclusions about the cause of the breakdown. A common cause of malfunction is low voltage in the on-board network. The fact is that for the amplifier to function, a supply voltage of 13.5V is required.

First of all, we test the battery, if everything is fine with it, then we’ll look into it further. The problem may have occurred when you removed the battery for charging. To make the electric booster work again, turn the wheels to the extreme position and back 5-6 times, very often this is enough to resume operation.

Wiring fault

In the case when the battery is in order, we look at the wiring; weather conditions, frost, rain or heat may be associated factors. If the electric power steering on a Priora turns off when weather conditions change, then this is a clear sign of a wiring fault. Check the soldering and insulation of the winding; a short circuit may occur.

The Priora's electric power steering does not work all the time. The maximum load on the electric motor occurs at low or no speed, and the minimum at high speed. So, in the Priora, at a speed of 110 km/h, the electric booster is completely turned off. At the same time, feedback to the steering wheel becomes maximum. The Kalina electric power steering switches off already at 60 km/h.

Chip errors

When a situation is observed that the wheels turn on their own, the reason is the electronic filling of the Priora electric power steering control unit. As mentioned above, quality was sacrificed for the sake of economy. Now the situation with this seems to have improved and everything has been finalized, but if suddenly you feel that the steering wheel is starting to move by itself, go for repairs.

If, along with the electric power steering, the speedometer also fails, then you need to look at the speed sensor. It was either simply dirty or broken. The same applies to the torque sensor installed on the amplifier. Clean them well and check their functionality.

Don’t forget to reset errors on the on-board computer; this can be done in several ways.

1. Remove the terminal from the battery, wait a few seconds and put it back, the error should go away.
2. Using a computer, the corresponding software can be found on the Internet.

Fuse box location

If you suspect that a fuse has blown and you want to check it, then the question arises: where is the Priora electric power steering fuse located? The control mounting block is located to the left of the steering wheel. Its opening scheme is simple. All you need to do is turn the three latches 90˚ and remove the cover, as shown in the photo, and you get to the brain stuffing of the car.

Here you can check and replace the failed fuse, then close the lid by pressing it tightly and snapping the three latches back 90˚ in the opposite direction.

You can carry out diagnostics and minor repairs to the Priora's electric power steering with your own hands. To do this, it is enough to determine what caused the failure and fix the problem, following our advice. It is better to entrust a complete replacement of the electric amplifier to professionals.

Electric power steering is a component used to provide more comfortable driving. Not so long ago, domestically produced cars began to be equipped with EUR, in particular, in this article we will talk about Lada Kalinas. What malfunctions can occur with the Kalina EUR and what troubleshooting methods are there? Find answers to these and other questions below.

Conclusion

Installing an EUR on Granta Standard is completely justified and necessary. To prevent breakdowns and incorrect operation of the mechanism, order services from certified service stations, where they provide a quality guarantee.

Negative reviews addressed to the EUR are caused by violation of operating conditions by the owners and unprofessional installation.

The electric power steering in the Lada Kalina is designed to provide increased comfort while driving. The car itself has only recently appeared on the domestic market, but has managed to gain considerable 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 compared to competitors in the class. In this article we will talk about malfunctions and ways to eliminate them.

Causes of EUR failure

Why does the electric power steering on the Lada Kalina not work, turns off and refuses to work, what are the signs of a steering wheel with power steering knocking, jamming, biting or squeaking? To repair the system yourself, you need to know how diagnostics are carried out and what causes precede the breakdown. Most often, the failure of the amplifier is caused by a breakdown of the unit itself and the amplifier fails. Problems of this type are resolved by thoroughly checking the system to identify the exact problem.

As practice shows, often the inoperability of the electric amplifier (failure) is associated with a breakdown of the speed controller.

• the steering wheel is jammed,
• jams
• becomes tight
• and others

Because the speed controller sensor ensures activation and deactivation of the electric power steering under different driving modes. The amplifier on Kalina works if the car is moving at low speed. When the speed begins to increase, the booster automatically turns off, allowing for safer machine control when driving at high speeds.

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

1. The speed controller has failed or the control unit does not receive or disappears a signal from it. In this case, the reason may lie in either a breakdown of the sensor, damaged wiring, or poor contact of the controller with the on-board network.
2. The voltage in the vehicle's electrical network has decreased. The reasons can be different, ranging from a dead battery and an inoperative generator to the use of inappropriate electrical equipment in the car.
3. The permissible crankshaft speed has been exceeded.
4. Incorrect operation or failure of the control module. Depending on the cause, the control unit may need to be repaired; more detailed diagnostics need to be done.

About qualified electric amplifier replacement

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

There are situations that do not allow you to resort to these two methods of eliminating an amplifier malfunction. Then the only solution will be to manually replace the mechanism that has become unusable.

Let us immediately make a reservation that the replacement process if the EUR does not work is characterized by sufficient complexity. To carry it out successfully, you will need experience and the possession of special tools. Unqualified replacement actions can aggravate the scale of the breakdown, which will entail a significant waste of money on more expensive repairs in service conditions.

Before the actual replacement procedure, we recommend that you carefully study the entire list of features and actions if the ESD 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, partial disassembly of the front panel of the Lada Kalina is necessary. After this, 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 it with a new unit. 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 that clearly comes to the driver from under the panel or the amplifier turns off. This phenomenon may be accompanied by a characteristic squeak that occurs during rotational actions with the LADA Kalina steering wheel. This situation is usually 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 be attentive and patient. All cable connectors must be tightly seated, and the device itself must be firmly secured. Only after this can you proceed to the reassembly of the previously dismantled front panel components.

Diagnostics

To check the amplifier in a car, you need to remove the plastic trim on the steering column; to do this, unscrew the bolts securing it from the bottom.

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 12 volt power;
• the red-brown contact is the connection cable to the tachometer;
• the gray contact goes to the car speed controller;
• white and pink wire - amplifier control indicator;
• black-yellow contact is a diagnostic line;
• the next contact is empty, the wire is not connected to it;
• brown contact is ground;
• empty.

Dismantling and disassembling the electric amplifier

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

How to remove the EUR with your own hands:

1. After removing the switches, you will need to dismantle the lower cross member of the dashboard. To do this, you need to press the fasteners that secure the connector with wires, and then disconnect the wiring from the control module. Once these steps are completed, you can disconnect the connector from the switches.
2. The system bracket is secured with nuts; you will need to unscrew them with a wrench.
3. After this, the steering rack will need to be carefully lowered down. To do this, you will need to find the bolt that secures the driveshaft to the booster shaft. This bolt must be unscrewed, but when unscrewing, you will need to fix the nut, this will prevent it from turning. When the bolt is removed, the fastening will need to be loosened, after which the intermediate shaft will be carefully removed. At this stage, we recommend marking the position of the shaft and gears; you can use a marker for this. This step is very important because doing it will prevent possible installation problems in the future. If the marks on the shafts do not match, this may cause problems with the amplifier. When dismantling, be careful not to damage the wiring, as this will also lead to the inoperability of the ESD.
4. When the unit is dismantled, it will need to be disassembled and the failed elements replaced. Further editing is done in reverse order (the author of the video is Murzik Bely).

Do-it-yourself electric power steering repair for Lada Kalina

DIY lambda probe repair

With the use of electric power steering on modern cars, driving has become much easier and more comfortable, and the ability to maneuver at low and high speeds has increased. However, with the increase in comfort, the prices for servicing such complex equipment have also increased. That is why repairing the electric power supply yourself is the most profitable option.

Lada Kalina cars are equipped with both an electric and mechanical amplifier drive. Despite all the differences, both types of drives have one thing in common - they are a common unit that can be quickly dismantled, followed by replacement and repair.

All ESD malfunctions are divided into electrical and mechanical.

Electrical faults of the electric booster

When troubleshooting electrical problems, be sure to remove the terminal from the battery. This procedure must be performed during any electrical work in the car.

Operation failure

It happens that when you turn the key in the ignition switch, the icon indicating a malfunction in the EUR turns on again. A possible malfunction is a breakdown of the amplifier drive motor. It is possible to fix such a malfunction yourself if you have electrical knowledge. If you are unable to repair the electric motor, it is recommended to replace it with another one.

Operation failure may also occur in the following cases:

• The fuse has blown. However, it is recommended to replace the fuse only after eliminating the cause of its blown. The fuse is designed to protect the electrical circuit from short circuits. When the wires are shorted, they heat up and the fuse link melts, breaking the electrical circuit. There is probably an overlap of wires in the circuit and their further short circuit. Eliminate the cause and only then change the fuse.
• Poor contact at the connections, resulting in a lack of power in the amplifier circuit. Correct the contacts or clean the wire connections.

Speed ​​sensor

One of the most vulnerable elements of the system is the speed sensor. This is an electrical device that is designed to control the electric drive of the amplifier at various speeds.

The fact is that using ESD at high speed can cause an accident, since the slightest rotation of the steering wheel will lead to the car being driven off the road. This sensor reads the speedometer and, as speed increases, weakens the power steering effect. Thus, it turns out that at high speed the power steering operates in the same way as when using a mechanical amplifier.

The main malfunction of the sensor is its failure. If the sensor fails, the amplifier circuit does not receive speedometer readings and the amplifier is turned off. After this, a special icon on the instrument panel lights up (steering wheel with an exclamation mark). In this mode, the amplifier operates without an electric drive and does not interfere with the steering. In this case, you just need to remove fuse F31 in the block to the left of the steering wheel to completely disconnect the circuit before replacing the speed sensor.

Ultimately, to fix this problem, you just need to change the speed sensor.

Mechanical problems

Mechanical failures of the power steering include various damage to the amplifier structure, jamming, deformation and fracture. In cases with mechanical faults, the electric amplifier must only be replaced.

How to tighten the electric power steering rack?

The appearance of a knocking sound in the operation of the electric power steering is associated with the need to tighten the steering rack.

How to do it right:

1. First you need to disconnect the battery; to do this, disconnect the terminals from it. Unscrew the battery mount; to do this, you need to unscrew two more nuts located at the edges. After this, the battery is removed and put aside.
2. Then you need to lift the plastic stand, there are four more screws under it, they can also be unscrewed.
3. Having done this, it is necessary to move this stand forward until the platform is disconnected from the air filter housing retainer pad. After this, the trim can be moved back, this will provide freer access to the rail itself.
4. At the next stage, you will need to crawl your hand under the rail. Directly below it, as shown in the photo, there is a rubberized cap; it will need to be removed, this will allow the key to access the adjusting nut.
5. To perform adjustment work, you will need a special wrench to tighten the rack; without it, the adjustment procedure will not be possible. Using this wrench, you need to crawl under the car rail to install the tool in the required hole.
6. When adjusting, be careful not to overtighten the rack. If its tightening is very strong, then when cornering the rack will bite, and this, in turn, may affect the safety of movement. The angle of adjustment is always different, it depends on how much the nut is loose, but usually when performing such work the nut is tightened by approximately 30 degrees. This should be enough to get everything right. After the adjustment is completed, it will be necessary to check that this task was performed correctly. That is, you will need to make sure that the steering wheel turns normally to any position all the way and there is no knocking. If the knock remains, then the adjustment continues.

Installation instructions

This manual is intended for those who have minimal skills in working with tools and vehicle systems. It is made as accessible as possible to everyone. But if you doubt your skills and knowledge, it is better to contact a car service.

Required tools and materials

First of all, you will need the EUR itself. Please note its serial number. The last two digits indicate the type and place of production.

So, 00 is a geared amplifier, produced in Makhachkala and has received complaints from drivers. With the numbers 04 - Korean, installed on Grants and Kalinas, a good amplifier, can be found in stores, but there are few of them on sale. Well, 02 - Kaluga, gearless type, also has good reviews.

To connect, you will need common tools such as screwdrivers, wrenches, and an angle grinder.

Installation process

First, you will need to completely remove elements such as the airbag, steering wheel, switches, ignition switch, and finally the steering column along with the bracket and cardan.

Then do everything as follows:

1. Taking the old bracket-plate, knock out the bolts from it. Then cut off about 30 mm from the top (where 2 bolts are welded and there are 3 holes).
2. Try the plate on the EUR, if the holes do not match (most likely this will happen), drill them.
3. Now you need to attach the gimbal to the amplifier.
4. You need to put washers under the bracket at the point of attachment to the amplifier. They can be of different thicknesses and have a direct impact on future steering adjustments.
5. Now you can attach the EUR. Insert the cardan onto the rack.

How can I lubricate and adjust the EUR?

How and with what to lubricate the amplifier?

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

1. First you need to remove the plastic casing; to do this, unscrew the bolts that secure it. To unscrew, use a Phillips head screwdriver. It is also advisable to remove the lower cross member of the instrument panel, located under the steering wheel.
2. Next, unscrew the two bolts that secure the amplifier itself; for this you will need a 13mm wrench. After this, the column can be released down.
3. Unscrew another bolt, after which you can do the actual lubrication.
4. First, the steering wheel is turned to the left until it stops. The lubricant is poured into a 10 cc syringe, which needs to be sprayed into the hole formed. You need to throw out all 10 cubes.
5. Then the steering wheel is turned to the right until it stops - the syringe is again directed into the hole, all the lubricant is sprayed out.
6. After this, the steering wheel should be turned to the middle position and again sprinkled with lubricant into the hole.
7. Next, the steering wheel must be turned in different directions until it stops several times. The lubrication operation is repeated again.
8. Then all the components are assembled in reverse order.
