To date, each prior is equipped with an electric power steering, it concerns the basic configuration. Although the device initially went as an additional feature of comfort. The owners of this model know that the unit does not rarely encourage and breaks, but with the need for repair you can perform with your own hands. About this further in the article.

Electric power steering, device and principle

Thanks to the operation of the electric power, there is a reduction in load and effort on the steering wheel when the turn is performed. The unit significantly facilitates the management of the vehicle and does not allow at high speed to make dangerous maneuvers. The node includes such elements:

• Electromotor.
• Shaft.
• Speaker.
• Wheel.
• Moment sensor.
• Electronic control unit.
• Power rotation mechanism.

When turning the steering wheel turns on EUR. The moment provides the electric motor present in the design of the electric power plate. The moment sensor performs the measurement of the indicator and sends it to the electronic unit. Depending on the angle of rotation, the computer calculates what power it is necessary to specify the engine. In the switch, which is located at the wheel, has a device that determines the angle of rotation. The rotation and moment sensors transmit information to the electronic unit, which determines whether the electric motor is functioning from the speed required.

At the last generations, the VAZ was mounted by a hydraulicer, which was actually the same force in all ranges of rotation. As for the electric powerful, the degree of effort here depends on the mass of factors: the rotation rates of the steering wheel and its angle, the speed of the power plant, the speed of the ride.

Electric power steering priory, weak link or not

Of course, the electric power steering is a very useful option, however, along with this he is a weak link of priors, since it occurs periodically.

Signs of full failure of the electric power plant VAZ

As practice shows, this unit does not have much faults, the breakage occurs in the same elements. The first thing to disassemble is a complete failure of the electric powerful. When the EUR turns off, check the screen of the on-board computer, most likely, you will see a code on it that reports faults in the unit. However, in some cases, to diagnose the disconnection of the EUR can only in practice. Follow these steps:

1. Turn off the motor and turn the steering wheel several times in different directions.
2. Repeat these actions, however, already when the engine is running.
3. Strength when turning the steering wheel did not change? So the unit turned off completely.

Electrical power steering does not work, can you drive a car

Even with a non-working electric power, you can continue to drive, but it is not recommended to do this. The driver needs time to drop from driving with the help of EUR. Therefore, it is desirable to immediately do diagnosis.

Speed \u200b\u200bsensor failed as it is reflected on the electric power steering and speedometer, how to fix

Sometimes the speedometer and the amplifier simultaneously stop working. The reason for such a defect is the failed speed sensor. It should be understood that these three components are connected. The moment sensor transmits information to the control unit. It compares it at speed, and then determines the effort. If the reason in the speed sensor, then the repair is reduced to checking the wiring, which leads to this component. You should also check the wires that connect the sensor with the steering amplifier and the speedometer. If there are no cliffs in switching, change the sensor.

EUR does not work due to low voltage, how to fix

Low voltage in the automotive network can also entail a shutdown of the electric power. Look for malfunctions in wiring insulation. When it is damaged, short circuits will occur in the network. In addition, insulation disorders are the cause of the malfunction of the generator. To troubleshoot the malfunction, check the generator and wiring. In the moment the sensor there are many contacts that in conditions of severe contamination contribute to the disconnection of the electric powerful. In this case, it is necessary to disassemble the unit and clear the contact sensor contacts.

The car does not listen to the steering wheel that with EUR, how to do the driver

The car moves along the smooth road surface, the position of the steering wheel does not change, but suddenly the car turns to the side. Such an unpredictable behavior of EUR requires urgent diagnostics, since at the most inappropriate time the electric power steering can send the car to the oncoming lane or on the roadside. In this case, it is necessary to stop driving and turn off the amplifier.

How to turn off the eur in detail

To disable the electric power, it is necessary to remove the fuse that is responsible for supplying the voltage to the EUR. To get this fuse, follow these steps:

1. Near the left leg of the driver is the cover of the mounting unit.
2. Tighten the locks and fold the mounts.
3. The block where the required fuse is located, is located near the expansion tank.
4. Remove fuse F5 (50 A).

The cause of such behavior is faults in the EUR device. This may be a control unit, a torque sensor, mechanical damage or clogged contacts.

Where to diagnose eur faults

It is recommended to perform diagnostics from professionals, because it will not be possible to check the control unit in the garage conditions. Replacement can be done with your own hands.

Preparatory work to replace EUR

Before removing the amplifier, it is necessary to dismantle a lot of details of the instrument panel: ignition lock, casing, steering wheel. When these items are removed, you can proceed to removal of the EUR.

Tools, fixtures, consumables

1. Deep heads on "8" and "13".
2. Chisel and hammer.
3. Ratchet and extension cord (as an alternative, you can use the gate).

Replacement EUR do it yourself, step-by-step instructions

1. Take the head to eight, put the ratchet and remove the contact group.
   
2. Completely remove the contact group from the shaft because it will interfere with you when parsing the node.
   
3. Pay attention to the gray block that is responsible for the EUR control. Disconnect the wiring from it.
   
4. Each plug has a separate retainer. Carefully examine its design, because when dismantling you can easily damage it. Then you will need additional repairs.
   
5. Then find the mount of the cardan and the steering rack - disagree them, for which you need to unscrew the bolt.
6. Loosen the Cardan's tie, in this case you will help the chisel and hammer. Now you have access to EUR mounts to the body. Unscrew the four nuts - two in front and two below.
7. Hold the node to avoid its fall. Drop the unit with the rail and completely dismantle it.
8. Installing a new device is performed in the reverse order.

Tips Prof.

Of course, the independent replacement of EUR - the event is a bit time-consuming, but not at all difficult even for a novice car enthusiast. Good luck!
