Is it worth installing electric power steering?

Driving a car without electric power steering is, of course, possible. But if you have previously driven a car equipped with such a system, you may experience serious discomfort. You will be deprived of the usual electric motor support.

Installing such a mechanism has certain difficulties and is also associated with costs. But they will all pay off in a comfortable ride and increased safety for you and your passengers.

Thus, the answer to the question “Is it worth installing?” - this is a definite “Yes”. Even if you don't want to do it yourself, contact a car service.

In the video below you will find a comparison of the advantages of power steering and power steering (the author of the video is AVTOTEMA TV).

Possible malfunctions of the EUR

It happens that after installation the EUR does not work at all or intermittently.

This can be caused by various reasons, among which two most often stand out:

1. Speed ​​sensor failure. The electric power steering operates in connection with the speed sensor. At high speeds, the extra force from the mechanism is reduced to give you more control. If data from the sensor stops flowing, the EUR will automatically turn off. The problem is solved by replacing the sensor.
2. Incorrectly installed engine crankcase. If there is a violation in the installation of the engine crankcase (casing), vibrations from the engine will be transmitted to the amplifier. It will begin to buzz, and in some cases even turn off.

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.

After all this you need to connect the wiring. Below is the connection diagram.

Equipment:

• Electric amplifier manufactured in Kaluga;
• Warranty card/passport for electric power steering.

1 year warranty.

This amplifier is installed instead of the standard one, as well as on vehicles not equipped with electric power steering (EPS) from the factory.

Important information for ordering! If the car was not equipped with electric power steering from the factory, you will need: a mounting plate to the body, a set (harness) of wires for connecting the power steering and a steering column driveshaft. If you purchase an EUR to replace your factory one that has failed for some reason, then in this case you do not need to purchase additional components!

When ordering, please indicate which vehicle you need the EUR for!

Note! By installing the EUR, you are making changes to the steering, the reliability of which you need to be completely sure of. The online store Motorring.ru sells EUR ONLY manufactured in Kaluga . Such power steering units are installed on the AVTOVAZ assembly line.

Some online stores sell EUR manufactured in Kizlyar or EUR made in Korea, which AVTOVAZ refused due to the possible spontaneous steering of a car with such an EUR. Such EUR, as a rule, are sold at prices of 1000-5000 rubles. cheaper.

We kindly ask you not to risk your safety!

Removal and installation of electromechanical power steering Lada Granta

Electric power steering reduces steering effort, making driving easier. The basis of the electric booster is a brushless electric motor with a gearbox located under the steering casing. A worm is installed on the motor shaft, which meshes with a plastic gear mounted on the steering shaft. The operation of the electric booster is coordinated by an electronic control unit that changes the voltage supplied to the electric motor based on information received from sensors of vehicle speed, crankshaft speed and the amount of torque on the steering shaft. The electric motor turns the steering column shaft through a gearbox with a certain torque.

The control unit provides sufficient steering information in all vehicle driving modes. When the car is stationary, the torque on the shaft created by the electric amplifier is maximum; as the vehicle speed increases, the “assistance” of the amplifier decreases and the steering wheel becomes “heavier.” If the electric booster fails, the car retains full controllability, while the steering wheel becomes somewhat “heavier” than on a car without an electric booster. since an additional load appears in the form of a freely rotating electric motor rotor

In the instrument cluster there is a fault indicator for the electric power steering. It lights up when the ignition is turned on and goes out after the engine starts. If the electric booster fails, the indicator lights up constantly. The electric booster does not work when the engine is not running.

The electric booster can be turned off:

— when the on-board network voltage decreases;

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.

It was necessary to transfer my wife from Kalina to Grant, and therefore difficulties arose with the steering, since Kalina has an ESD, but Grant does not and the tires cost 195.

As a result, a kit was ordered for installing the EUR on the Grant:

1. Gearless electric power steering manufactured by JSC Avtoelektronika, 11186-3450008-02 (122.3405010-02); 2. Intermediate bracket for installing the EUR, 11186-3403172-00; 3. Intermediate non-separable steering shaft “TAYA”, 72780. 4. Wiring harness for connecting the EUR, 2110-3724155;

Assignment of EUR contacts

According to fragments of the diagram from the document “ELECTRICAL CONNECTION DIAGRAMS OF LADA GRANTA CARS”, the following contacts of connectors X1 and X2 of the EUR are used:

X1-1 - power +12V. Connect to the positive terminal of the battery through a 50A fuse; X1-2 - power mass of the electric power steering. Connects to the ground point of the body EUR;

X2-1 - signal +12V. Used to power control circuits. Connects to pin 56 of the fuse block; X2-2 - ECU tachometer signal output (X2-F4); X2-3 - ECU speed sensor output (X2-E3); X2-4 - instrument panel ESD malfunction lamp (pin No. 20 of the instrument panel connector); X2-5 — K-line output for connection to the OBDII diagnostic block (pin No. 7); X2-6 - L-line output. It is not used in the circuit, but it may be present in the harness - just pull out the terminal with the wire from the connector so as not to get tangled. By closing the 6th contact to ground or the 7th contact, the EUR diagnostics is started. The error code is generated by the number and duration of flashes of the dashboard ESD malfunction lamp; X2-7 - signal mass of the electric power steering unit. According to the diagram, it is connected to the S22 twist, which is connected to the car body, but I could not find the connection point, so it was connected separately to the center console.

Cars of the Lada Grant family are equipped with power steering as standard. Electromechanical power steering (hereinafter referred to as EPS) is installed individually by the owners.

Electromechanical power steering

ESD is a relatively new development of modular control, which, like power steering, has advantages and disadvantages.

MECHANISM DEVICE

The EUR can have a device with several layout options:

1. The mechanism has a steering rack that perceives force.
2. The electric motor transmits force to the steering shaft.

Most often, cars use electric power steering with a caterpillar track. There is a parallel drive mechanism design that uses two gears. The classic railroad design includes an electric motor, a manual transmission, and an on-board computer that controls everything. Technically, the device combines mechanical and electrical parts into a single whole. The operating principle of electric power steering is based on the operation of an asynchronous electric motor.

Steering rack adjustment

The unit knocks for various reasons. In fact, this is a real disease of the control mechanism, inherited from the Lada Kalina, since the components are identical on these cars. You can adjust the rack yourself.

To do this you will need a minimum of tools:

• steering rack calibration key;
• socket heads for 10 and 13;
• shaped screwdriver.

To tighten the slats, you can use two methods. The first involves using a special key that can be inserted into the gap of the arch on the left side. The second method is more labor-intensive and is suitable if it is not possible to stick your hand into the gap. To do this, you will need to dismantle the battery and its platform; this is the only way to get to the nut for tightening the gearbox. The first method is simple, so it’s better to consider the second option.

To do this, you need to disconnect the battery terminals and remove it, and then remove the platform under it. Now you can get to the nut located on the inside of the gearbox housing. You can buy a combination wrench for tightening, on the one hand - for tightening the rack, on the other - for tensioning the timing belt.

To tighten the nut, turn it clockwise.
