We install electric power steering on a VAZ 2114 with our own hands


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.

Electric power steering for VAZ 2114

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.

Installation instructions


Installing the main unit

When installing an electric power steering, it is necessary to take into account that it will be necessary to replace the steering column of the VAZ 2114 with an “electrically driven column”. To do this, let's start with the wiring. You will need to deal with the pads. There will be no need for any “twists”. There is a terminal in the block that we need to remove and insert into the block in the harness.

We insert the free terminal of the harness exactly into the place where the standard wire was. You don't need a special harness for this. Connect two 4 square wires to the battery. Don't forget to connect a 50A fuse. The “weak point” will connect to the tachometer, speed sensor, ground, K-line and wiring to the warning lamp. Don't forget to check the presence of speedometer and tachometer signals.

  1. Remove the casing with switches and ignition switch.
  2. Unscrew the bolt on the rail and remove it. We need to determine how much larger the “native” part is than our new one.
  3. We install the shaft on the EUR. After this we attach the shaft itself in its place.
  4. Setting up the wiring. We stretch two cables to the battery from the passenger compartment, preferably through the left wing. To conduct wiring you can:
  • First remove the washer fluid reservoir.
  • Take a solid wire and drag it through, trying to get to the hood.
  • As soon as it appears near the hood, we attach our wires to it.

  • We pull it out together with our wire.
  1. We connect the EUR electronics. There is a red connector under the instrument panel with an orange wire in it. It is to this that you need to connect the electric amplifier.
  2. Similar procedures must be done with the gray wire.
  3. We connect the power ends. In the battery we connect the pink one is a plus, and the black one is a minus.

The installation is now complete. If you did everything carefully according to the instructions, you will enjoy the ease of driving the VAZ 2114.

Installing electric power steering on a VAZ 2114

I rode my father’s viburnum and realized that there was no escaping progress, especially since I plan to change the rack by 3.2, or even 2.5 turns, and without an amplifier there will be no life at all. I bought it at Stinger. The kit includes everything you need: 1. The amplifier itself (a new model, not glitchy in short). 2. Adapter. 3. Steering shaft. 4. Wiring. From myself: 1. I don’t see any problems with the mechanics. 2. For electrical purposes, you need to look for a connection diagram.

I started to disassemble: 1. Removed the steering casing (nothing complicated). 2. Disconnected and removed all switches (wipers and lights). 3. Removed the ignition switch (the first problem is that you need to unscrew the bolts with a chisel, since there are no edges (!). 4. Use a chisel to straighten the clamp securing the shaft and steering rack (at the engine shield). 5. Use a chisel to unscrew the two bolts securing the steering column (also quite inconvenient). the adapter is attached, I'll clamp it in a vice and knock it out through the sleeve). 10. Measured so that only a little bit came out of the nut and sawed it off (you can use a grinder, I made do with a saw and a file). EUR to the adapter (four nuts for 13 plus growers). 14. Replaced the ignition switch (I used hex bolts, it’s more convenient).

Electrics

Mechanically: I bought: 1. Adapter for steering wheel (for Priora). 2. Steering column switch block (also from Priora) 3. Steering column cover from Priora (not yet available). I installed everything, although I haven’t figured out the sound signal yet, but I’ll do that one of these days)). Electrics: 1. Extended the power wires to the battery (plus with a fuse, minus just a wire). 2. Tightened the ground (black thin wire for controlling the power steering, screwed under the instrument cluster). 3. Connected the wires to the instrument cluster. 3.1. The orange wire from the red block to the first from the EUR block is double yellow-red (photo 2). 3.2 Gray + yellow wires from the red block to the third from the EUR-blue block (photo 4). 3.3 Brown-red from the white block to the second block from the EUR-brown block (photo 3). In photo 5 from bottom to top: 1. Yellow-red. 2. Brown. 3. Blue. 3.4 There are also wires there, for k-line and so on, I didn’t connect them (wiring for Priora is not provided in Samara). 4. Collected everything.

Now the feelings: 1. Yes, everything is super 2. At low speeds it’s just a fairy tale) 3. As the speed increases, it turns off and the car steers as before (that is, clear and intelligible feedback). 4. Unlike the early Kalinovsky EURs, this one, when turned off, does not betray its presence in any way (I don’t feel it at all).

Disadvantages: 1. Because of the adapter, the steering wheel dropped (not fatal, but still). 2. The bullet column has lengthened, the steering wheel has become closer to the driver (in principle, everything can be treated by adjusting the seat and I, at 186 cm, did not experience any inconvenience). 3. The steering wheel covers the instrument cluster.

Block (red) of the instrument panel harness to the instrument cluster; 9. Block (white) of the instrument panel harness to the instrument cluster; 10. Alarm block; 11. Ground terminal.

From myself: THE COLOR OF THE EUR WIRES MAY DIFFER.

1. Button: well, it’s not realistic to put it in its regular place, so I had to think about it. The task was to save the button, not to cut the wiring and place it in a convenient place - as a result, it is now on the panel. I am comfortable.

2. Tilt of the steering column: I placed washers under the far fasteners (which are closer to the engine compartment) of the EUR with an adapter, with them the angle of the steering column changed and the steering wheel no longer covered the instrument cluster.

Adjusting the steering wheel position

If you don’t like the height and position of the steering wheel, then you will need to grind the edges of the shaft to the size you need or install gaskets between the plate and the body. It is worth remembering that the electric power steering is automatically switched off at speeds above 50 km/h, unlike the same power steering.

Installing electric power steering on your own is quite possible. You just have to remember that even for an experienced driver it will take a lot of time and effort. But for a lover of comfortable driving, the result will justify all costs and hopes.

How to install electric power steering on a VAZ 2114

2001 was the year of the appearance of a new project from the domestic automaker AvtoVAZ. The model had two names - Samara-2 or VAZ 2114. In fact, it was an improved version of the well-known nine.

EUR kit

The modernization turned out to be very serious, affecting literally all components of the car. The steering system was no exception. Unlike many other models produced by AvtoVAZ, the 2114 offered a choice of two power steering units at once - hydraulic power steering and electric power steering.

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:

  1. Remove the steering wheel and the cover that covers the column.
  2. Remove the steering column switches.
  3. Disconnect the hazard warning button and disconnect the chip from the ignition switch.
  4. 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.

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.

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.

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:

  1. Plate for installing electric drive. With its help, an adapter is made between the electric power steering brackets and the standard one.
  2. Cardan shaft to connect your car's steering rack and electric power steering shaft.
  3. 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.

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.

  1. 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.
  2. 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.
  3. 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 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. But there is another side to the issue - firstly, the cost of the power steering or electric power steering kit, as well as the rather complicated installation of the system yourself. In general, it’s up to you to decide, but if you decide to install an electric booster on your car, we will help you with the installation.

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:

  1. Disconnect the negative terminal from the battery.
  2. 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.
  3. 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.
  4. 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:

  1. The speed sensor must be connected to the right chip.
  2. The wire coming from the tachometer must be connected to the left chip.
  3. 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.

Possible problems

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.

A fairly common problem caused by the fact that the hydraulic booster operates directly from the power unit. In order to correct the situation, the hydrach is connected not directly to the engine, but using a gain regulator. Another option is to use an amplifier with an electric drive function. Today, such a device is not difficult to find, and it costs relatively little.

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.
