Electric power steering on the Lada Kalina is a guarantor of simplified and comfortable car operation

The purpose of the EUR, as you know, is to provide a more comfortable driving experience. Relatively not so long ago, domestic-made cars began to be equipped with this type of power steering. What is an electric power steering on a Lada Kalina car, what malfunctions are typical for it and how to replace the assembly, read below.

Components of the electric power steering and the principle of its operation

On a Lada Kalina car, the electric power steering is a special unit that connects to the steering system and allows for soft and smooth operation of the steering wheel. Due to the fact that the car has an installed electric booster, traction when turning the steering wheel will be of better quality, respectively, the driver will need to exert less effort.

As for the design of the device itself, according to the standard, it consists of:

• first of all, the electric power steering circuit includes an electric motor;
• an equally important component is the control unit;
• reduction device;
• the system is also equipped with three controllers - torque, speed, and rotation of the crankshaft.

The Kalina system, as you can see, is generally simple in design. Despite its simplicity, even such a device makes it possible to obtain all the necessary data and provide easier vehicle control. An on-board computer is used to control the functioning of the node. It should be noted that the node itself does not always function. It comes into operation when the number of revolutions reaches 400 per minute and turns off if the vehicle speed is more than 60 km / h.

In accordance with the connection scheme, such restrictions allow for the most optimal properties and enable the driver to drive Kalina in the interval considered the most difficult. In addition, such features were introduced by the manufacturer for security reasons. After all, when driving at high speed, the operation of the steering rack with electric power is more dangerous. As we have already reported, the use of this node makes the steering wheel more sensitive, respectively, this can lead to certain risks when driving at high speed. So when driving at a speed of more than 60 km / h, the device turns off automatically, making the overall movement of the driver in the car safer.

EUR malfunctions and subsequent device diagnostics

As mentioned above, installing an electric power steering on Kalina involves the use of a device that is quite simple in design. Accordingly, the repair of the unit and troubleshooting in general is not a particularly complicated procedure. But it should be noted that the scheme for connecting the EUR, namely the location of the node, was not chosen very well by the manufacturer. This is because the installation of the EUR is carried out under the heater radiator. So when using the car in the winter season, the node will be affected by various temperatures, in particular, their difference.

This is what largely affects the breakdown of the node and, as practice shows, in fact this happens quite often. The failure of the electric power steering is associated with the appearance of problems in the operation of the vehicle control and the appearance of various malfunctions.

As a rule, the failure of the mechanism contributes to:

• lack of impulse from the speed controller;
• failure of the system control unit;
• too low voltage in the on-board network of the vehicle;
• the permissible threshold of the unit's revolutions has been exceeded.

These factors, as practice shows, contribute to the breakdown of the mechanism. As for diagnostics, it is carried out by the Kalina control unit independently during the launch of the node and analysis of the health of all systems. If any of the components does not transmit the corresponding signal, the control unit automatically enters it into the list of non-working devices. Relevant information can be seen on the control panel. In particular, if we are talking about the failure of the EUR, then an orange indicator in the form of a steering wheel with an exclamation mark will appear on the tidy.

In accordance with the service manual, the manufacturer claims that the problem of a node malfunction should be resolved in the near future. Therefore, the car owner needs to drive at a reduced speed to the nearest maintenance and repair repair station. But this is all - official data, in fact, things are somewhat different.

As a rule, the appearance of an indicator on the control panel does not imply the need for repair, usually its appearance indicates a malfunction in the unit. We can talk about both malfunctions in the operation of the power circuits, and the breakdown of one of the controllers. As practice shows, in most cases, the appearance of a light bulb on the shield does not affect the functioning of the unit as a whole (the author of the video is the CompsMaster channel).

In fact, a breakdown is considered a problem, in which the steering sensitivity will be too low. This kind of malfunction usually occurs quite often and, as a rule, they need to be addressed really immediately. Otherwise, if the problem is ignored, it can lead to sad consequences. To quickly solve the problem, first of all, it is necessary to dismantle the fuse located to the left of the steering wheel. Thanks to this, you will be able to get to the nearest service station for repairs.

VAZ employees claim that the EUR is beyond repair. If it breaks, it must be replaced!

Electric power steering replacement

The procedure for replacing a node in a Lada Kalina car should be carried out exclusively by experienced specialists. In the event that the warranty period for your vehicle has not expired, then, of course, to fix the problem, you must contact an authorized dealer. If the warranty for the car is no longer covered, and, as you know, the cost of repairs can be quite high, you can try to solve the problem by replacing the assembly. But before proceeding to its elimination, it must be taken into account that the replacement procedure itself is not very simple. So if you don't have the technical knowledge, experience, and skills to do this task, it's best not to even attempt it.

Always remember that incorrect actions during the repair can lead not only to a complete failure of the system, but also to a rather complicated and expensive repair of the unit. So the installation of an electric amplifier should be carried out only after you have studied all the components, details and features of the system. In this case, first of all, you need to familiarize yourself with the connection diagram of the node. To dismantle the system, you will have to partially disassemble the center console, namely the panel installed under the steering wheel. You will need to disconnect all the wires that go to the node.

As practice shows, the installation of a new node in most cases may not be required, since usually the problem can be solved by taking preventive measures. In fact, one of the most common problems in the operation of the knot is knocking. This knock usually occurs when turning the steering wheel and in most cases it is accompanied by a squeak. To solve the problem of such a plan, it will only be enough to lubricate the assembly. If this does not help, then further you will need to make a more thorough diagnosis or replace the node.
