Humor in the subject: – I am an honest and decent girl! During registration, I told my friend at the registry office: “I promise to love you, remain faithful to you, respect and care, take care of you and believe you... until some interesting man separates us.”
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.
Operating principle of the EUR
Every time you turn the steering wheel, the torsion shaft twists. Information about this process is transmitted from the torque sensor to the control unit online.
Based on the information received, the electronic control unit (hereinafter referred to as the ECU) accumulates information and reads readings from other sensors. The ECU transmits a signal to the electric motor, which increases the torque of the steering rack shaft by activating the electric motor.
Information is processed so quickly that tenths of seconds pass from the moment of transmission to the moment of reading.

Possible malfunctions of the EUR on the Lada Grante Liftback (Sedan)
| Malfunction | Diagnosis | Elimination method |
| The diode on the side pillar glows due to a faulty speed sensor. | Checking the serviceability of the speed sensor by dismantling it and ringing it with a multimeter. | Replacement of the sensor with a new one, since the design is not subject to repair (partial, complete). |
| Low voltage in electrical wiring. | Checking the integrity of the insulating layer and contact terminals. | Replacement of damaged cable sections, insulation of connection points. |
| The electric amplifier rotates slowly. | Checking the voltage supply to the input contacts from the relay regulator. | Replacing the relay regulator. |
| During rotation, a characteristic creaking, metallic grinding sound is heard. | Dismantling the EUR, disassembling it into its component elements, checking the condition of the rolling bearings. | Replacement of two rolling bearings with new ones. |
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.

MECHANISM DEVICE
The EUR can have a device with several layout options:
- The mechanism has a steering rack that perceives force.
- 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.

Recommendations for choosing an electromechanical amplifier
For installation on cars of the Lada Granta family, we are considering modifications from a domestic manufacturer. There is no point in purchasing foreign analogues with a 50% increase in cost.
We buy spare parts exclusively from certified points of sale. The best place is in branded stores from OJSC AvtoVAZ.
We install the electric power steering ourselves. We re-read the article’s recommendations and watch video lessons as needed.
Preparatory stage before installing the EUR on the Lada Granta
Note to the driver! There are no differences in installing the EUR on the Lada Granta Sedan and the Lada Granta Liftback. Factory mounts are identical.
- EUR (11186-3450008-02): synchronous power unit, control controller, brackets, shaft, gearbox;
- intermediate bracket (11186-3403172-00);
- non-separable intermediate steering shaft (72780);
- blocks with wires for connecting to the central power circuit (2110-3724155);
- LED indicating the good condition of the amplifier;
- plastic clamps;
- fasteners;
- set of automotive tools;
- insulation;
- clamps.
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.

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.
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).
