Do-it-yourself installation of EPS (electric power steering) on a VAZ 2114: instructions

Since the production of the VAZ-2114, it has been planned to install additional control kits. These are such as power steering and electric power steering, but they are not included with the new car. So, every motorist would not refuse to have one of these systems to simplify driving.

The video will tell you how to install electric power steering on a car, and also tell you about some of the nuances and subtleties of the process.

What is needed for installation

You will need to directly purchase electric power steering for the VAZ-2114; users have only positive reviews of various manufacturers of these devices. And the cost of such devices ranges from 15,000 to 25,000 rubles. The following elements must also be included in the kit:

Plate for installing electric drive. With its help, an adapter is made between the electric power steering brackets and the standard one.
Cardan shaft to connect your car's steering rack and electric power steering shaft.
Electrical wiring kit for installing the device.

If you purchase this device in a store, be sure to check the package contents. If some elements are not in the box, then it is better not to buy the device, as problems may arise during installation.

If noticeable scratches appear on the body of your car, do not rush to have the car repainted at an auto service center. Small paint chips, cracks, scuffs and scratches can be repaired yourself using a regular can of paint.

A story article that talks about how a guy repaired the heater of a BAZ 2110. From it you will learn why the heater in this car can malfunction, how it can be repaired repair, and why it is better to immediately contact a car service.

The article will be useful to owners of the VAZ 2109. It is dedicated to repairing the gearbox. Here it is explained how the malfunction occurs, typical problems and how to fix them. You will learn how to determine that the oil has expired.

Electric power steering on the VAZ-2114 is installed only by the owners; none of the cars were equipped with such devices from the factory. But to increase comfort and improve control, motorists install electric amplifiers from Priora or Kalina.

Minor difficulties may arise during installation. But it will be much more difficult to pass the technical inspection. Essentially, you are tampering with the steering design, which is strictly prohibited by traffic rules. The driver has no right to make changes to either the steering or the brake system.

The feasibility of installing EUR

Does it make sense to install power steering (power steering) or power steering on the “four”? In this case, it is impossible to give a universal answer, since it is unique for each motorist. Of course, with power steering or electric power steering, the process of turning the steering wheel will be easier, making driving more comfortable.

Installation kit for electric power steering for the "four"

Types and advantages of power steering

The steering of the VAZ 2114 has undergone significant changes when compared with its predecessors in the form of the first generation Samara. Driving has become really better.

Installation kit

Customers had the opportunity to choose between electric power steering and power steering, that is, electric power steering and power steering. But how do these systems differ from each other, which one should you prefer and why? Let's try to figure this out.

Electric booster

Electric power steering operates using pulses of electrical current. This is a rather complex system in which each individual part has its own important role. Because of this, when at least one unit fails, the operation of the entire device is disrupted, it can completely stop working.

Electromechanical amplifier circuit

The task of the car owner whose car has an EUR installed is to constantly monitor the condition of the unit. A special controller is responsible for the operation of current pulses. With its help, the driver can independently set the degree of gain.

The EUR performs several tasks.

It has a positive effect on handling, maneuverability, perfectly holds the car on the road, and allows you to feel the car. Remove the electric booster, and driving becomes a complete test of the driver's nerves and physical fitness.
It copes well with temperature changes, which are especially typical for the Russian climate. Even extremely low temperatures do not affect the electric power steering, which allows the entire steering system of the car to adequately withstand such operating conditions.
The power from the electric booster has a positive effect on fuel consumption. By adjusting the degree of gain, you thereby control the appetite of your car. So the appearance of EUR on the VAZ 2114 became a landmark event for the domestic automobile industry.

Power steering

The hydraulic booster includes a large number of elements that require not only constant monitoring, but also careful handling.

The operating principle of the power steering is based on the interaction of the steering with the oil fluid, which is contained in a special container. This is where the name of the type of amplifier comes from, since the work is based on the force of the working fluid.

Despite the rather complex technology, power steering is effective, safe, provides comfortable control, and allows you to control the behavior of the car even if the front wheels break down.

Alas, the hydraulic booster is not without its drawbacks. The main one is frequent breakdowns. They arise mainly due to leakage of working fluid.

The functions of the power steering are as follows:

The car becomes more obedient, maneuvers well, and responds to the driver’s steering input;
Provides softening of impacts on the steering wheel when passing difficult road sections. There are more than enough of these in our country;
The hydraulic booster is ideal for regular driving on country roads. In this component, the electric amplifier is significantly inferior to the power steering;
The driver feels the road better, makes timely decisions, and the system responds to them;
Strengthening due to the working fluid allows you to reduce the number of revolutions of the steering wheel rim to perform maneuvers. This saves the driver's effort.

The electric power steering on the VAZ-2114, the installation description of which will be given below, has a number of advantages when compared with hydraulic devices. The hydraulic booster requires a pump that creates pressure to operate the steering wheel. And these are already unnecessary elements in the design.

The condition of the pump must be constantly monitored; leaks may appear in it, which will lead to failure of the power steering. The electric device is much simpler, its service life is very long, it is undemanding in maintenance, which will be very useful for lazy drivers. And most importantly, the cost of an electric amplifier is almost half as much. And when operating a car there are no costs at all.

Detailed Installation Guide

So, if you decide to install electric power steering on a VAZ 2114, then you need to take into account that you will also have to replace the steering column itself. In particular, instead of a standard device, you will need to install a column with an electric drive; accordingly, our repair process will begin with the wiring.

The free terminal of this connector is installed in the place where the standard wiring ran; no special harnesses or adapters are required for this. You only need to connect two 4 square cables to the battery. To ensure the safety of this section of the electrical circuit, it is additionally necessary to install a 50 ampere safety element.

Next, using the so-called weak current, that is, not a power wire, you need to connect to the following elements:

tachometer, used to display the number of revolutions of the engine crankshaft;
a speed sensor used to indicate the speed of the vehicle;
mass, that is, the car body;
diagnostic K-line;
as well as to the control light (the author of the video about installing the unit at home is the sokur64 channel).

After completing these steps, you will need to diagnose the presence of a tachometer signal, as well as a speedometer.

If there are signals, then the further installation procedure is as follows:

The plastic casing on the steering column, where the switches are installed, as well as the ignition switch, is dismantled. To do this, you need to unscrew all the bolts that secure the protective cover.
Then you need to unscrew the screw installed on the rail and dismantle it. At this point, you will need to determine how much the size of the assembly installed during production differs from the size that will be used.
At the next stage, the shaft is mounted directly on the electric amplifier. After this, the shaft itself must be fixed at the installation site.
The next step is to configure the electrical circuit. It is necessary to run two wires from the vehicle interior to the battery; alternatively, this can be done through the left fender. To do this, you must first dismantle the expansion tank of the washer system, and then, using the hardest and thickest wire, stretch it. You need to try to get to the engine compartment.
When the end of the wire appears in the engine compartment, you need to attach the wiring to it. Next, both wires will need to be pulled out along with the wire itself.
Having completed all these steps, we proceed to one of the main steps - connecting the electric amplifier electronics. Under the dashboard in the “four” there is a special red block, inside of which there is an orange cable. The EUR contact itself must be connected to this wire. The same actions are performed with the gray wire.
Then the power ends are connected. Pink and black wires are connected to the battery, pink to the positive terminal, black to the negative. At this point, the installation process can be considered complete. Check the functionality of the installed system and, if necessary, adjust the device.

Possible problems

Everything about installing electric power steering on a Lada Granta in a garage

Some drivers note that in a VAZ 2114 with a hydraulic booster, the control system becomes as if weightless. This can be confusing. When the gain is lost, the steering wheel has to be turned more often.

Wiring

As for replacing the hydraulic booster with an electric booster, this is a more than possible option for improving the car. It is considered one of the simplest but most effective types of technical tuning. However, it is strongly not recommended to perform such operations yourself.

Choose specialized car services that specialize in technical modifications and tuning of the car. AvtoVAZ cars, which include the VAZ 2114, are beautiful because they are literally created for tuning. Many young drivers choose the “fourteenth” model as their first car. This is due to the wide possibilities for modification with minimal investment. This car lends itself perfectly to external tuning, and the current spare parts market makes it possible to improve the internal filling. This includes replacing the power steering with electric power steering.

Next you need to connect the EUR. The connection diagram is as follows:

Connecting the small black EUR block

1 orange +12 after the ignition switch - white block pin 4 and to the EUR diagnostic LED +12

2 brown - tachometer - white block pin 8

3 gray speed sensor - red block pin 3

4 white-pink - on the EUR diagnostic LED there - ground

5 yellow-black - K-line to the diagnostic block (does not affect operation)

6 green is not used, although also on the diagnostic block

7 brown mass - to mass

Large gray block EUR connection

1 red thick wire + to the battery to the positive terminal

2 black thick wire - to the battery at the negative terminal or to the car body

The EUR diagnostic LED was installed in the instrument panel

Disassembling the steering control

Before installing the electric power steering on the VAZ-2114, the photo of which is given in the article, you need to perform several preparatory steps:

Remove the steering wheel and the cover that covers the column.
Remove the steering column switches.
Disconnect the hazard warning button and disconnect the chip from the ignition switch.
Completely disassemble the steering column.

It is advisable to have the operating instructions at hand when carrying out work; everything is explained in it very clearly. After dismantling the steering column itself, you need to unscrew the studs and screws. Screws with shear-type heads must be unscrewed using a chisel.

The work is very tedious and boring, but you will complete it quite quickly. After unscrewing the top bolt securing the cardan to the column, completely free the mechanism. After this, dismantle the steering column and remove the cardan by unscrewing the bolt on the lower mount. It may be necessary to loosen the clamp located at the bottom of the cardan using a chisel.

Maintenance

To enjoy high-quality EPS work for a long time, you must follow these rules:

do not allow the electrical mechanism to be subjected to physical impacts;
prevent moisture from entering the system and do not expose it to high temperatures;
when replacing the control unit, calibrate it;
Avoid interfering with the steering column.

Important! The savings with ESD are obvious: after all, the system only works during the turn

Removal and installation

As an example, we consider the dismantling and installation of the ESD on a VAZ Lada Kalina car.

Before carrying out this type of work, you should definitely prepare:

screwdrivers (phillips and flat);
hexagon (13).

It is also impossible to complete all the actions on your own, so you will need a partner.

To remove the amplifier, follow the step-by-step instructions:

Disconnect the negative battery terminal.
Place the wheels of the car in the straight position.
Remove the steering wheel and switches under it from the car.
Remove the paddle shifters.
Remove the 3 screws securing the amplifier to the panel.
Remove the amplifier.
Disconnect the wire connectors from the EUR terminals.
Use a marker to mark the positions of both the universal joint and the booster shaft.
Unscrew the nut on the universal joint and remove the bolt.
Unscrew the two nuts of the front fastening, and then the rear one, and remove the EUR.

Installation of the electric amplifier is carried out in the reverse order of the above steps.

Did you know? There are 1.8 million more registered cars in Los Angeles than there are people with licenses.

Mechanism repair

Electric amplifier repair includes:

electrical rack diagnostics;
determining the cause of the error being issued and removing it;
repair of the EUR motor.

If the car is under warranty, then repairing the electric booster yourself will be a wrong action. For repairs, you should contact a service center. If the sensors are faulty, you can even replace them yourself.

Calibration

Calibration is to ensure that the steering wheel can return to the "straight" position. There is a special scanner. It connects to the diagnostic connector. The specialist turns on the calibration program.

This procedure is carried out for several reasons:

after performing wheel alignment;
when a signal from the corresponding lamp appears on the panel;
in case of steering wheel deviation from the zero position;
after the battery terminals have been removed;
when replacing disks;
in connection with the reinstallation of the EUR.

Did you know? On premium cars, the electric booster can control the movement independently if the car is driving in a straight line.

Change of oil

There is no oil in the electric booster. There is ERUG - a hybrid of electric and hydraulic booster. It is necessary to check the level and color of the liquid in such a system.

Usually a condition check is carried out either after a certain mileage, or for the following reasons:

noises that appear (hum, crackling);
tight steering reversal.

Types and advantages of power steering

Power steering

If you are not satisfied with the position of the steering wheel or its height, this can be corrected by adjustment. To do this, it is necessary to grind the edges of the industrial shaft to the required dimensions or install gaskets between the device body and the plate. When making adjustments, you must remember that the EUR itself is automatically turned off when the vehicle speed exceeds 50 km/h.

Price issue

The cost of electric power steering for a VAZ 2114 car may vary, depending on the store where it is purchased, as well as the region of the country. On average, the price for a complete system set varies around 22-24 thousand rubles. On the Internet, you can search for stores where the EUR kit is sold on promotions - with a discount from the seller, you can purchase the unit for 20 thousand rubles.

Requirements

I think that if you find this material useful, another article will be created. In it we talk about what problems can happen with this node.

For example, we have already separately studied the reasons for the squeaking of the steering wheel when rotating. The issue of when the steering wheel does not return to its original position was also considered separately. In these cases, hydrach is also often a potential culprit.

In order for the power steering to ensure reliable and high-quality operation, it must meet certain requirements. Among them:

reliability and build quality;
noiselessness;
ease of even self-service;
minimum possible dimensions;
environmental friendliness;
automatic return of the steering wheel to its original position;
smoothness;
proportionality of efforts;
maintaining the functionality of the steering unit in case of power steering failure, etc.

Really important requirements. And even if the power steering no longer meets them, the driver should still be able to get to the nearest service station or his garage, for example. And don’t just stand there idling and wait for a tow truck.

Device installation

After dismantling all steering components, it is necessary to install the plate. Before this, use a grinder to file the upper studs and install the electric power steering housing, cardan and plate; all these elements are included in the kit.

Electric power steering on a VAZ-2114 (a detailed description is given in the operating instructions) can be installed in literally a matter of minutes. It will take you much longer to dismantle all the elements. When installing, be sure to change the standard cardan to the one included in the kit. Don’t rush to assemble the steering column just yet, because you still need to connect the device to the car’s on-board network.

Power steering pump

The pump of this mechanism deserves a separate discussion. It costs about 3 thousand Russian rubles and is often repaired rather than replaced. But if repairs don’t help, you’ll have to spend money. As for high-quality repairs, you can again do it yourself, thereby saving your money.

VAZ 2110 has a hydraulic booster on the car

Typically, a ZF brand pump is installed on the VAZ 2110 power steering, which is also used on the Audi A6, Volkswagen and other cars. But this pump model is not dismountable and there are no retaining rings or covers on it. This does not mean that it is impossible to restore the operation of such a pump. Below are instructions for removing and disassembling the power steering pump:

Remove the clamp;
Disconnect the return hose (do it carefully so as not to spill oil);
Disconnect the connector;
Remove the DJ (sensor) from the fitting bolt.

We disconnect the discharge tube, first removing the union bolt;
Remove the power steering drive belt;
Now it's time to start removing the pump itself;
Loosen the first bolt securing the pump;
We completely unscrew the second bolt securing the pump;
Remove the pump assembly.

VAZ 2110 power steering fluid

We clean the pump from dirt and visually inspect it. If a development is found on the inner wall of the housing, resembling steps, then they need to be removed using a special nozzle and a drill.

Pump bearing and seal

VAZ 2110 with power steering

A worn bearing in a sealed housing can also cause power steering failure. The cuff, which needs periodic replacement, is no exception.

Let's consider both options:

To secure the bearing in the first way, you need to make a groove on a lathe on the outside of the housing. Then we drill threaded holes in the pump wall. The new bearing should be inserted and secured using bolts with sharpened ends, which are also sawn off.
The second option involves bending the edges of the body.

We assemble the pump in reverse order. Unlike other pump models, the ZF version has vanes that do not turn over.

The power steering pump may make noise after installation. But there is no need to be afraid of this, because everything is explained simply: grinding in parts.

Connection to electrical equipment

The electric power steering control unit takes a signal from the speed and crankshaft speed sensors. Connection to the vehicle electrical systems is carried out as follows:

Disconnect the negative terminal from the battery.
Locate the spare sockets in the fuse box. You need to connect the device through them. Find the reserve wire in the harness, connect the power supply to the electric power steering unit.
If it is not possible to use backup sockets, then you need to power the electric amplifier from the ignition switch through a fuse. So that when the ignition is turned off, the electric drive does not work.
The negative power wire must be connected to the car body.

At this point, the connection of the power section can be considered complete. Connecting controls is done as follows:

The speed sensor must be connected to the right chip.
The wire coming from the tachometer must be connected to the left chip.
Install both chips on the electric power steering.

This completes the connection. You can install electric power steering on a VAZ-2114 with your own hands without any problems. But it’s better to do all this at a service station so that the technicians can issue you a document confirming the correct installation of the equipment. Only in this case will you get rid of problems during maintenance.

Replacement

This technology is as important as pouring oil into the box of a VAZ 2109, which can be done independently or at a service station. An oil change must be done immediately after purchasing a used car. This recommendation is explained by the fact that the new owner does not know what fluid the previous owner of the car used. In such circumstances, you should also pre-flush the engine. The same should be done if the car has not been used for a long time.

Before starting the procedure you need to prepare:

new fluid and filter;
key to 17;
rags for wiping;
container for draining waste material.

The work is carried out as follows:

The engine is warming up. This must be done to make the liquid more fluid, which will make the whole process go faster.
It is better to place the car on a flat surface above the hole. This will make it easier to get to the bottom.
By placing a drain container under the bottom of the machine, you can unscrew the drain plug. The oil will flow immediately, so it is better to wear gloves on your hands.
At the end of the drain, which will take about 10-15 minutes, the plug is installed in place.
The oil filter is unscrewed and a new one is installed. First you need to pour about 200 ml of liquid into it and the sealing gum is treated with lubricant.
New oil is added. It will take about three liters.
After filling, you need to check the fluid level. If it is not enough, it is necessary to gradually add lubricant, constantly monitoring its volume using a dipstick.
At the end, you need to close the lid and turn on the engine for a few minutes, letting it idle.

Functionality check

After you have connected all the elements of the system, you need to install the steering wheel and check the functionality of the mechanism. If you are satisfied with the work, then you need to assemble all the elements in the reverse order. After this, start the engine and try turning the steering wheel at low speed.

https://www.youtube.com/watch?v=vjwdqpR7BkE

In this case, the electric drive should work to help you turn the wheels in the desired direction. Then you need to accelerate the car. At high speed, the electric power steering on the VAZ-2114 should not work. Otherwise, you most likely made a mistake when connecting the wires coming from the sensors.

How to install power steering on a VAZ 2114

From its very production, the steering system of the VAZ 2114 car assumed the possibility of installing power steering using an installation kit.
This also applies to electric power steering or simply EUR. This modification will make it easier to turn the car and increase comfortable handling. This is especially true for drivers who drive in the city most of the time.

The main difference between power steering (power steering) and electric power steering is that the strength (efficiency) of the former directly depends on the speed of the engine. At high speeds, turning the steering wheel is too easy. This affects both ride feel and handling.

To overcome such problems, the power steering is not connected directly to the motor, but using a gain regulator. This is exactly the functionality that an electric amplifier has. The operation of the electric power steering is not characterized by a direct connection between effort and motor power, which allows it to be used as much as necessary in a specific situation.

For the VAZ 2114, a similar EUR is suitable as for the Lada Priora.

Additional advantages of using an electric booster instead of power steering:

Less maintenance requirements (no need to monitor oil, connections).
In cold weather there is no need to warm up, as when using power steering.
Installing the EUR is much easier (no need to interfere with the engine compartment).
High reliability.
The only downside is the lower power, although on passenger cars like the VAZ 2114 this is not at all noticeable.
