Today, all Lada Kalina owners are interested in the question: why does the electric power steering on the Kalina not work? After all, this car began to be produced back in November 2004, with electric power steering as standard. The ten-year anniversary has passed, but according to reviews from car enthusiasts, this problem still exists.
The electric amplifier consists of an electric motor, a force transmission mechanism and an electronic control system. The operation of the electric booster is controlled by an electronic unit with three special sensors, which must quickly determine the speed of the car, engine speed and the required force to turn the front wheels.
When starting the engine with the starter, the electric power steering (EPS) does not work. It turns on only when reaching 400 rpm
crankshaft and stops working when the car accelerates over 60 km. at one o'clock.
EUR glitches
The EUR began to turn off.
So I arrived, I think this crap visited me too. A quick inspection: the fuse is intact, the speedometer is working, the power supply voltage is normal. The indicator on the panel will light up and then go out. The amplifier is the same, sometimes it doesn’t work at all, sometimes it works even at high speeds. Let me remind you that the amplifier reduces its force with increasing speed. What to do? Call a friend! It’s good that my brother-in-law is an auto electrician))) More options have appeared, a position sensor, or an EUR controller. Confirmation of the diagnosis only after diagnostics... Diagnostics will decide how much money to save... about 15 kilo rubles for a new EUR or I’ll get away with little loss. We agreed with him for diagnostics on the weekend. But I can’t sit and wait, so I went online. I found an article. How to carry out diagnostics using a scraper))) Are you getting burned? I, too, was freaked out until I tried it... About diagnosing Kalina's electric power steering. Diagnostics of EMUR without a scanner
Lately, many questions have arisen regarding the diagnosis of electromechanical power steering (EMPS) of cars of the LADA KALINA family. Not all scanners support this diagnostic function.
As a first aid, we can suggest reading the EMUR fault codes using the “paperclip” method, for which you need to do the following:
* turn off the ignition; * close contacts 6 and 7-pin connector of the EMUR control unit (CU), located next to the power supply unit; * turn on the ignition and read the codes through the flashing diagnostic lamp.
If you look at the ECU connector from the wire side (8-pin black connector, 1st pin on the top right near the latch), then from right to left the count goes like this:
* 1-blue (ignition switch +12V); * 2-brown-red (tachometer); * 3-gray (vehicle speed); * 4-pink-white (EMUR control lamp); * 5-yellow-black (K-Line); * 6-blank (L-line) * 7-brown (mass) * 8-blank.
Light code timing parameters:
* duration of the initial pause – 2 seconds; * long signal duration – 2 seconds; * short signal duration – 0.5 seconds; * pause duration between signals – 0.5 seconds; * pause duration between codes – 2 seconds
* 11 The system is working * 12 No engine speed signal * 13 Malfunction of the torque sensor * 14 Malfunction of the EMUR engine * 15 Malfunction of the steering shaft position sensor * 16 Malfunction of the EMUR engine rotor position sensor * 17 Malfunction of the vehicle's on-board network (below 10V or more than 18V) * 18 Malfunction EMUR control unit * 19 Vehicle speed sensor malfunction
I got 19, speed sensor... Fuck, but the speedometer works. Well, to hell with it, I went to the store. Speed sensor viburnum 375 rubles. Put. I set off, after about 5 meters the EUR turned on, the indicator went out. Happiness has no limits!

Debriefing
The electronic control unit (ECU) for the electric power steering is mounted in a bad place, under the heater radiator
. Any leakage of this part causes the ECU to get wet, after which you will feel that the power steering is not working and the steering wheel has become heavy.
If while driving you notice that the tachometer or speedometer needle is at zero and does not move, rest assured that the ESD of your car is not working. This happens because these devices and (EUR) are activated from the same sensors.
Most often on Kalina, the speed sensor fails. Buying a new sensor and replacing it solves this problem. There are very often cases when replacing sensors does not help, (the electric power steering) still does not work. Begin to methodically probe the entire chain of wires related to the system (EUR).
Due to the constant vibration of the car and poor quality of production, connecting plugs and blocks independently break electrical circuits at the most inopportune moment.
Kalina's power steering behaves poorly during on-board voltage fluctuations
. If an old generator produces less than 30 volts instead of 15 volts, then the electronic control unit of the power steering may also refuse to work.
If you broke down on the way
In recent years, the production of Lada Kalina cars (ECU) of domestic production was replaced with Korean ones. The kind they put on Hyundai cars. After that, power steering failures became significantly less frequent. But they started installing Korean blocks
. And how many thousands of Kalinas travel all over the roads, with old electronics?
Our advice to you is, at the first opportunity, change the electronic control unit on your car to a modern one, you will be healthier.
Electric power steering for modern cars has already become an integral part of them. On the Russian market it was first installed on the Lada Kalina ( VAZ 1118 ). The electric booster added both a lot of positive emotions and a lot of negative ones. Failure of this unit occurs quite often on the first samples. Our guest today was no exception – a car from the Lada “Kalina” family (Fig. 1).
The situation is quite typical: the client complains that sometimes the electric power steering turns off and the electric power steering warning light comes on, but after driving along some hole or rails, the electromechanical power steering (EMUR or EPS) resumes its operation.
This situation is very annoying, because not only the owner uses the car, but also his wife. It is much more problematic for a woman to turn the steering wheel without electric power assistance.
We start the car, and the electric power steering fault light actually lights up and it becomes quite difficult to turn the steering wheel. It is imperative to deal with this problem.
We connect the diagnostic scanner and connect to the EMUR control unit.
On the monitor screen we see the following error: C1044 – incorrect sequence of the rotor position sensor. What is a rotor position sensor and where is it located?
Let's take a break from our malfunction for a moment and touch on a little theory. Let's understand the EMUR device and what main parts it consists of. Let's consider all its parts separately.
What malfunctions threaten the EUR on Kalina and what are the ways to eliminate them?
Electric power steering is a component used to provide more comfortable driving. Not so long ago, domestically produced cars began to be equipped with EUR, in particular, in this article we will talk about Lada Kalinas. What malfunctions can occur with the Kalina EUR and what troubleshooting methods are there? Find answers to these and other questions below.
LADA KALINA (VAZ 1118) - electric power steering diagram
One of the new products of the Russian automobile industry, the Lada Kalina, became the first domestic car equipped with EMURU - electromechanical power steering. How does Kalina electric power steering work? A separate large article will be devoted to the answer to this question. We will only note that as the speed the car picks up increases, the compensating torque of the electric power steering gradually decreases, and when it reaches 60 km/h it turns off automatically. At first, this part was not completely “finished” and had one dangerous property - it could turn off while the car was moving, regardless of its speed limit. It should be noted that today all these problems are a thing of the past. Let us add that the electric amplifier can be completely turned off by removing one of its fuses. True, the steering will become even “heavier” than on the “ten” or “fourteenth”.
The EMURU device operates from the vehicle’s on-board electrical network with a voltage of 10.8 to 15V.
Causes of EUR failure
Why does the electric power steering on the Lada Kalina not work, turns off and refuses to work, what are the signs of a steering wheel with power steering knocking, jamming, biting or squeaking? To repair the system yourself, you need to know how diagnostics are carried out and what causes precede the breakdown. Most often, the failure of the amplifier is caused by a breakdown of the unit itself and the amplifier fails. Problems of this type are resolved by thoroughly checking the system to identify the exact problem.
As practice shows, often the inoperability of the electric amplifier (failure) is associated with a breakdown of the speed controller.
Because the speed controller sensor ensures activation and deactivation of the electric power steering under different driving modes. The amplifier on Kalina works if the car is moving at low speed. When the speed begins to increase, the booster automatically turns off, allowing for safer machine control when driving at high speeds.
So, briefly about the reasons for the inoperability of the EUR:
Symptoms of a problem
It is impossible to immediately understand why the electric power steering does not work on Kalina. However, in most cases of malfunction (EUR), a light indicating a steering wheel with an exclamation mark should light up on the instrument panel. After which, specialists from the VAZ automobile plant recommend driving at low speed to a car service center.
Why at low speed? Because in the first years of production (EUR) by the Makhachkala plant, it had the peculiarity of turning the drive wheels of the car as far as possible to the left or right and independently locking itself in this position.
The electric motor and mechanical part (EUR) rarely cause complaints, but the electrics and electronics require a detailed study of breakdowns.
Diagnostics
To check the amplifier in a car, you need to remove the plastic trim on the steering column; to do this, unscrew the bolts securing it from the bottom.
Then you will need to get to the 8-pin plug, its pinout is as follows:
More accurate results will be obtained by checking the amplifier using a scanner. But since such equipment can usually only be found at service stations, you can try to check the operation of the system with a paper clip.
To check you need to do the following:
How to understand where to look for the cause by the blinking indicator icons:
Error codes
c1044 - incorrect sequence of the rotor position sensor (RPS)
c1621 - incorrect voltage 5V
c1622 - speed signal circuit failure
c1011 - car engine speed signal circuit, no signal - the signal from the idle sensor (or the standard tachometer through a voltage limiter) is divided by 4 and applied to the tachometer input,
c1022 - error, voltage of the main output of the torque sensor - it is possible that the shaft cover has rubbed the insulation and the middle, green wire shorts to ground
Warning icons on the panel
The steering wheel icon can light up in two colors. If the yellow steering wheel is on, then adaptation is required, and when a red image of the steering wheel with an exclamation mark appears, you should already be concerned about the failure of the power steering or power steering system. When the red steering wheel lights up, your steering wheel will probably become very difficult to turn.
The immobilizer icon usually blinks if the car is locked; in this case, the indicator of a red car with a white key signals the operation of the anti-theft system. But there are 3 main reasons if the immo light is constantly on: the immobilizer is not activated, if the tag on the key is not read or the anti-theft system is faulty.
The handbrake icon lights up not only when the handbrake lever is activated (raised), but also in cases where the brake pads are worn out or the brake fluid needs to be topped up/replaced. On a car with an electronic handbrake, the parking brake light may come on due to a glitch in the limit switch or sensor.
The coolant icon has several options and depending on which one is lit, draw conclusions about the problem accordingly. One red lamp with a thermometer scale indicates an increased temperature in the engine cooling system, but a yellow expansion tank with waves indicates a low coolant level in the system. But it is worth considering that the coolant lamp does not always light up at a low level; perhaps there is simply a glitch in the sensor or float in the expansion tank.
The washer icon indicates a low fluid level in the windshield washer reservoir. Such an indicator lights up not only when the level actually decreases, but also if the level sensor is clogged (the sensor contacts become coated due to poor-quality liquid), giving a false signal. On some vehicles, the level sensor is triggered when the washer fluid does not meet specifications.
The ASR icon is an Anti-Spin Regulation indicator. The electronic unit of this system works in tandem with ABS sensors. When such a light is constantly on, it means the ASR is not working. On different cars, such an icon may look different, but often in the form of an exclamation mark in a triangle with an arrow around it or the inscription itself, or in the form of a car on a slippery road.
It often lights up when the catalytic element overheats and is quite often accompanied by a sharp drop in engine power. Such overheating can occur not only due to poor cell throughput, but also if problems arise in the ignition system. When the catalyst fails, high fuel consumption will be added to the burning light.
The exhaust gases icon , according to information from the manual, indicates a malfunction in the exhaust gas purification system, but, as a rule, such a light starts to light after poor refueling or the presence of an error in the lambda probe sensor. The system registers misfires of the mixture, as a result of which the content of harmful substances in the exhaust gases increases and, as a result, the “exhaust gases” light comes on on the dashboard. The problem is not critical, but diagnostics are worth doing to find out the cause.
Revitalization of the EUR
About a few days ago I started the car and I saw the EUR light up on the panel, I turned the steering wheel - it doesn’t work, I turned off the car, started the same garbage, drove it for a drive, started it in the evening of the same day - the EUR works. Then I noticed that the EUR began to turn off while driving, “I restarted the car when it helped and when it didn’t. Ultimately, I found out that the DPR (roter position sensor) had failed.
Reasons for malfunction:
1. Rotor position sensors (optocouplers) - inspect the soldering and solder with rosin. 2. Relay in the central block - if Russian, change it to a bourgeois one (TYCO) 3. On the first releases, quartz on the processor - change it to a better one 4. Torque sensor - soldering of winding wires (under sealant), sometimes burnt diodes and a zener diode Now yours: 5. In the torque sensor, replace the LOW DROP stabilizer, which is prone to self-excitation, with a regular one and bypass it with capacitors across the input and output 6. Shitty connectors, just solder them directly with mgtf and fill them with sealant 7. If you want, pour high-quality liquid lubricant into the gearbox and adjust the clearance in the engagement - so that there is no knocking and no jamming. It won't work with washers - it will sharpen the body. The reactive force is an order of magnitude better.
I read on the Internet that the ESD can be diagnosed without a scanner (using the “paperclip” method).
Diagnostics of EMUR without a scanner (paperclip method)
As a first aid, we can suggest reading the EMUR fault codes using the “paperclip” method, for which you need to do the following:
* turn off the ignition; * close contacts 6 and 7 (8) pin connector of the EMUR control unit (CU), located next to the power supply unit; * turn on the ignition and read the codes through the flashing diagnostic lamp.
What to close:
If you look at the ECU connector from the wire side (8-pin black connector, 1st pin on the top right near the latch), then from right to left the count goes like this:
* 1-blue (ignition switch +12V); * 2-brown-red (tachometer); * 3-gray (vehicle speed); * 4-pink-white (EMUR control lamp); * 5-yellow-black (K-Line); * 6-blank (L-line) * 7-brown (mass) * 8-blank.
Light code timing parameters:
* duration of the initial pause – 2 seconds; * long signal duration – 2 seconds; * short signal duration – 0.5 seconds; * pause duration between signals – 0.5 seconds; * pause duration between codes – 2 seconds
Decoding the code
* 11 The system is working * 12 No engine speed signal * 13 Malfunction of the torque sensor * 14 Malfunction of the EMUR engine * 15 Malfunction of the steering shaft position sensor * 16 Malfunction of the EMUR engine rotor position sensor * 17 Malfunction of the vehicle's on-board network (below 10V or more than 18V) * 18 Malfunction EMUR control unit * 19 Vehicle speed sensor malfunction
Be careful what you close! Triple check that you have found the correct contacts!
Decoding the code:
1 long 1 short System OK 1 long 2 short No engine speed signal 1 long 3 short Malfunction of the torque sensor 1 long 4 short Malfunction of the EMUR engine 1 long 5 short Malfunction of the steering shaft position sensor 1 long 6 short Malfunction of the engine rotor position sensor EMUR 1 long 7 short Malfunction of the vehicle electrical system (below 10V or greater than 18V) 1 long 8 short Malfunction of the EMUR control unit 1 long 9 short Malfunction of the vehicle speed sensor
I got error No. 16 (Rotor position sensor malfunction).
In order to get to the optocouplers, you don’t need to remove the steering wheel, and you don’t need to disconnect the driveshafts either. It is necessary to remove the steering column covers, disconnect all the harnesses (steering column switches, from the ignition switch, etc.), unscrew the four nuts securing the EUR bracket with a 13 mm socket wrench and lower the EUR with the steering wheel onto the seat. Disconnect 3 connectors from the EUR electronics unit (counting from the steering shaft - first the torque sensor (TM) connector, then the “brains” connector, the power cable connector, and finally the DPR connector) - disconnect everything except the TM. Unscrew the three screws and remove the cover under which the DPR board is located. Next, unscrew 3 more screws and remove the DPR board.
Please note that one of the screws securing the DPR board places one of the board contacts on the ground (there are only two insulating spacers on three screws) - during assembly, do not confuse where the spacer should be placed and where not.
It took no more than 10 minutes, after assembly and installation of the EUR in place.

The exclamation mark is on - what to do?
We have noticed that new topics often appear on car forums where drivers ask about the exclamation marks that are displayed on the Lada Priora panel.
They rarely specify where it is lit and what is depicted on the icon. In this section we have collected a small FAQ
Listed below are all the exclamation marks that can light up on the instrument panel of a VAZ 2170 car. The designations for these icons are as follows:
- The red exclamation mark in the circle (bottom) is lit. The indicator indicates that there is a problem with the vehicle's brake system. This is usually a low brake fluid level. Add it to the tank and, most likely, the sign will stop lighting. If this does not happen, then it is worth checking the system for damaged components. When igniting, the indicator lights up for 4 seconds and then goes out.
- The red exclamation mark in the triangle/circle (above) is lit. Modern versions use a triangle instead of a circle. The indicator tells us about defects in the operation of the brake force distributor. Use extreme caution if the light comes on while driving.
- Exclamation mark next to the steering wheel icon. When illuminated for a long time, it indicates a malfunction in the electric power steering (EPS). Like other icons, it lights up when ignited and goes out after a few seconds if the system is working properly.
New Lada: LADA Vesta family of the new model year - Official LADA website If the red triangle lights up while the engine is running, then you should diagnose the brake force distributor
Sometimes the indication is caused by faults in the electronics. Terminals are coming off, contacts are oxidized, defects in the on-board computer are a few reasons for the random appearance of icons.
To avoid damaging one of the systems, check the electronics first. To do this, it is enough to dismantle the device on the Lada Priora and see if the terminals are securely seated in the sockets.
If the brake system indicator lights up, first check the fluid level in the reservoir, and only then fill in new antifreeze.
Hello. The steering wheel light came on in the panel with a yellow exclamation mark. And when this sign lights up, the tape recorder turns off. And the sign is always off. It disappears and then appears again.
Before this I changed the brake disc and pads. They also told me to change the silent blocks. Changed the oil. What could it be?
- The temperature sensor in the Honda Fit came on - 1 answer
This icon means that the electric power steering is disabled. You need to check the actual voltage of the generator (there may not be enough voltage), if the voltage is normal, then carry out diagnostics with a scanner, check for errors in the ECU memory, then check the connector, wires, and the power steering itself. The steering wheel should turn tightly.

Tell me, I can’t find anywhere what the icon on the instrument panel in the form of a schematic “steering wheel” with an exclamation mark means, when you insert the key into the lock and turn it lights up along with the other icons and then, like everything else, it goes out, what does it mean, Yaris sedan 2008 "American"
to grandm: You most likely have electric power steering. This is an indicator of its malfunction.
It doesn’t light up like all the icons when you turn the key, and then goes out like all the other icons, I just couldn’t find anywhere what it means, thanks for the clarification
to Messier:
Good afternoon, when you turn on the ignition, the ECU gives a command for self-diagnosis of the entire system, that’s why all the icons on your dashboard light up and after a while they go out (but not all of them! Some go out when you start the engine)
And the “steering wheel with an exclamation mark” icon itself, yellow or red, means that you have electric power steering. If it lights up while driving a car or with the engine running, then this is already bad (indicates a breakdown of the power steering system)
Drivers are notified of the presence of malfunctions in various vehicle systems using icons on the instrument panel. It is not always possible to decipher the meaning of such burning icons intuitively, since not all car enthusiasts are well versed in cars. In addition, on different cars, the graphic designation of the same icon may differ. It is worth noting that not every light on the panel only indicates a critical malfunction. The indication of light bulbs under the icons is divided into 3 groups by color:
- Red icons indicate danger, and if any symbol lights up in this color, you should pay attention to the signal from the on-board computer in order to take measures to quickly resolve the malfunction. Sometimes they are not so critical, and it is possible to continue driving the car when such an icon on the panel is on, but sometimes it is not worth it.
- Yellow indicators warn of a malfunction or the need to take some action to drive the car or service it.
- The green lamps of the symbols inform about the vehicle’s service functions and their activity.
We will present a list of the most frequently asked questions and an explanation of the icons and indicators that light up on the instrument panel.
There are many badges with a car silhouette emblem. Depending on additional elements, this indicator may have different meanings.
When such an indicator lights up (a car with a key), it informs about malfunctions in the engine (often a malfunction of some sensor) or the electronic part of the transmission. To find out the exact cause, you will need to perform diagnostics.
A red car with a lock lights up, which means that there are problems in the operation of the standard anti-theft system and it will be impossible to start the car, but if this icon blinks when the car is locked, then everything is normal - the car is locked.
A yellow vehicle indicator with an exclamation mark notifies the driver of a hybrid vehicle that there is a problem with the electric drive. Resetting the error by disconnecting the battery terminal will not solve the problem - diagnostics are needed.
Everyone is used to seeing the open door icon lit when a door or trunk lid is open, but if all the doors are closed and the light on one or four doors continues to shine, then often the problem should be looked for in the door terminals (wire contacts).
The slippery road icon begins to flash when the stability control system detects a section of slippery road and is activated to prevent slipping by reducing engine power and braking the slipping wheel. There is no need to worry in such a situation. But when a key, a triangle, or a crossed out skid icon appears near such an indicator, the stabilization system is faulty.
The wrench icon pops up on the display when it’s time to perform vehicle maintenance. It is an information indicator and is reset after maintenance.
What malfunctions threaten the EUR on Kalina and what are the ways to eliminate them?
Electric power steering is a component used to provide more comfortable driving. Not so long ago, domestically produced cars began to be equipped with EUR, in particular, in this article we will talk about Lada Kalinas.

What does the exclamation mark mean?
The illumination of a red exclamation mark on the instrument panel informs the driver that the fluid level in the brake system is insufficient. When this sign lights up on the instrument panel, it is necessary to stop the car as quickly as possible, check the level of brake fluid in the reservoir, as well as the brake line for leaks.
The fluid level should be between the minimum and maximum marks; if there is not enough liquid in the tank, it must be added.
If, during inspection, leaks of brake fluid are found from the fittings of hoses and tubes or other connections, it is prohibited to continue driving.
Causes of EUR failure
Why does the electric power steering on the Lada Kalina not work, turns off and refuses to work, what are the signs of a steering wheel with power steering knocking, jamming, biting or squeaking? To repair the system yourself, you need to know how diagnostics are carried out and what causes precede the breakdown. Most often, the failure of the amplifier is caused by a breakdown of the unit itself and the amplifier fails.

Because the speed controller sensor ensures activation and deactivation of the electric power steering under different driving modes. The amplifier on Kalina works if the car is moving at low speed. When the speed begins to increase, the booster automatically turns off, allowing for safer machine control when driving at high speeds.
So, briefly about the reasons for the inoperability of the EUR:
Dismantling and disassembling the electric amplifier
Before removing the amplifier, you need to remove all the steering column switches. Remove the steering rack cover and dismantle the devices, remembering to disconnect the connectors from the power supply.
How to remove the EUR with your own hands:
- After removing the switches, you will need to dismantle the lower cross member of the dashboard. To do this, you need to press the fasteners that secure the connector with wires, and then disconnect the wiring from the control module. Once these steps are completed, you can disconnect the connector from the switches.
- The system bracket is secured with nuts; you will need to unscrew them with a wrench.
- After this, the steering rack will need to be carefully lowered down. To do this, you will need to find the bolt that secures the driveshaft to the booster shaft. This bolt must be unscrewed, but when unscrewing, you will need to fix the nut, this will prevent it from turning. When the bolt is removed, the fastening will need to be loosened, after which the intermediate shaft will be carefully removed. At this stage, we recommend marking the position of the shaft and gears; you can use a marker for this. This step is very important because doing it will prevent possible installation problems in the future. If the marks on the shafts do not match, this may cause problems with the amplifier. When dismantling, be careful not to damage the wiring, as this will also lead to the inoperability of the ESD.
- When the unit is dismantled, it will need to be disassembled and the failed elements replaced. Further editing is done in reverse order (the author of the video is Murzik Bely).
Diagnostics
To check the amplifier in a car, you need to remove the plastic trim on the steering column; to do this, unscrew the bolts securing it from the bottom.
Then you will need to get to the 8-pin plug, its pinout is as follows:
More accurate results will be obtained by checking the amplifier using a scanner. But since such equipment can usually only be found at service stations, you can try to check the operation of the system with a paper clip.
To check you need to do the following:
How to understand where to look for the cause by the blinking indicator icons:
Error codes
c1044 - incorrect sequence of the rotor position sensor (RPS)
c1621 - incorrect voltage 5V
c1622 - speed signal circuit failure
c1011 - car engine speed signal circuit, no signal - the signal from the idle sensor (or the standard tachometer through a voltage limiter) is divided by 4 and applied to the tachometer input,
c1022 - error, voltage of the main output of the torque sensor - it is possible that the shaft cover has rubbed the insulation and the middle, green wire shorts to ground
Why may TJ levels decrease?
The reasons for the decrease in level may be the following factors:
- Brake fluid leak;
- Pad wear;
- Damage to the fuel oil level sensor;
Brake fluid leak
This problem can occur after driving on deep snow or gravel roads, where brake line tubes and hoses are at risk of damage. Leaks are also possible at the connections of the calipers and the main brake cylinder.
Pad wear
When the pads are worn out, the caliper piston comes out of the seat much more than with new pads, therefore, the volume of fluid required to fill the space increases, and the fluid level in the reservoir drops.
When replacing the pads with new ones, the level should be restored to normal.
Damage to the fuel level sensor
This reason occurs quite often. The cap of the brake fluid reservoir contains a sensor that measures the fluid level; when it drops, the contacts on the sensor close and the lamp on the instrument panel lights up in the form of a red exclamation mark, informing that the brake fluid level is low.
Quite often it happens that the fuel fluid level is within acceptable ranges, but the indicator still lights up, this indicates a malfunction of the level sensor or its power circuit.
Error codes for EMURU "Lada Kalina"
So, we have studied the general circuit of the Lada Kalina electric power steering; now we will consider possible digital error codes and briefly describe their meaning. Note that equipment can be diagnosed using a DST-2M scanner with an installed VAZ-IZH cartridge or MT-10 software.
• C1000 – no error detected. • C1011 – no signal (engine speed circuit). • C1012 – no signal (speed sensor circuit). • C1013 – the voltage in the on-board network has dropped. • C1014 – the voltage at the ignition switch has dropped. Torque sensor: • C1021 – voltage (main output). • C1022 – voltage (control pin). • C1023 – incorrect output signal. • C1024 – no signal. Steering shaft position sensor: • C1031 – circuit malfunction (main signal). • C1032 – circuit malfunction (control signal). • C1033 – lack of power. Engine rotor position sensor: • C1041 – phase A circuit – malfunction. • C1042 – phase B circuit – malfunction. • C1043 – phase C circuit – malfunction. • C1044 – incorrect sequence. • C1045 – lack of power. Power circuits: • C1050 – short to ground. Motor, overcurrent: • C1051 – phase winding A. • C1052 – B. • C1053 – C. Broken phase windings: • C1054 – broken windings. • C1055 – winding A. • C1056 – B. • C1057 – C. Closing of phase windings: • C1058 – closing of windings. • S1059 – winding of phase A. • S1060 – B. • S1061 – C. • S1070 – unidentified. ECU - electronic control unit: • C1071 - RAM error. • C1072 – ROM error. • C1073 – EEPROM error. • C1074 – block relay. • C1075 – the radiator temperature is exceeded. • C1076 – ECU supply voltage. • C1077 – voltage for power capacitors. • C1078 – capacitor charging time. • C1079 – excess current in one of the windings. • C1080 – breakdown of the power transistor. Currently, DST-2M scanners are no longer produced; their place has been taken by more modern and advanced devices of the DST-12 model. With this equipment, you can diagnose not only faults in the Lada Kalina electric power steering. The DST-12 scanner is universal; it is used to service many cars - both those manufactured by AvtoVAZ and models from other manufacturers.
