The State X1 on-board computer, which is not at all large in size, is capable of performing a variety of climatic, route and diagnostic functions. It is installed on cars of the VAZ family - Kalina, Niva, 2123, 2110 and others.

1. What Staff X1 can do - information about computer functions
2. Diagnostics with a scanner - are the components of your car working normally?
3. Self check- decipher error codes

1 What Staff X1 can do - information about computer functions

• Diagnostic tester. Performs the function of a digital speedometer, tachometer, controls the operation of the power unit and throttle valve(tuned or standard), reads system diagnostic codes, notifies about the electrical voltage in the car and the engine temperature.
• Trip computer. Useful and convenient mode. In it, the on-board computer on the VAZ State shows the driving speed (average value) for one trip, the distance traveled by the car, the remaining fuel in the tank and its consumption per trip, and travel time. The BC also predicts the driving range on the remaining fuel and has a fuel counter.
• Supervisor. The device is equipped with an idle time counter and non-volatile memory; it notifies the driver about the direction indicators and dimensions not being turned off, as well as about a rollback (spontaneous) of the vehicle.
• Signaling device. State reports excess speed threshold, about problems in the on-board network and about potentially dangerous overheating of the power unit for the car.

• On-board computer VAZ 21099
• Checking the throttle position sensor
• Dingo on-board computer - practicality on a minimal budget
• Auto scanner for self-diagnosis of any car

In addition, State X1 has three additional functions that we liked to domestic motorists. The Tropic mode implies automatic control of the cooling system of the machine. The Plasmer is responsible for drying the candles and their subsequent warming up to a temperature that allows the production of cold start engine, Afterburner resets when switching fuel from gas to gasoline and vice versa.

A small nuance. The Afterburner function works exclusively with high-quality brands of gasoline (95 and above). Installation of the State X1 is carried out without the slightest difficulty in the plug available on the instrument panel.

You will need instructions for installing the BC into a specific VAZ car model. The installation principle is the same. You need to remove the cover from dashboard, and then alternately connect the same-color factory wiring with the wires on-board computer. State X1 does not require special settings. Install the BC, turn on the ignition, start the device, and it immediately goes into mode trip computer. If you need to switch to diagnostic mode, press the CORR button. The BC switches to alarm (emergency) mode independently.

2 Diagnostics with a scanner - are the components of your car working normally?

An on-board computer is a device that helps the driver when operating a vehicle. Today we will talk about the domestic device State Kalina X5 M. The computer is designed specifically for this VAZ model, which makes it easy to connect and use.

1. Standard on-board computer options State X5 M
2. New device functions - what to expect from manufacturers in the future
3. Installing the device yourself - how to avoid mistakes

1 Standard on-board computer options State X5 M

Next useful option- “Plasmer”. By turning on this function, the owner of Lada Kalina launches an influx additional impulses to the spark plug electrodes. So on frosty days, the Lada starts up much faster, and the computer produces fewer error codes. The "View ECM Errors" function is designed to visually view codes.

Another very useful option for Russian drivers is “Fuel Quality Control”. Using the “-” or “+” icons, the on-board computer shows percentage the quality of the gasoline being filled. Thanks to the “Power Unit Parameters” option, the Lada driver has the opportunity to see a clear picture of the engine’s condition; time spent heating it; as well as the battery charge level and voltage indicator in the instrument panel sensors. If the motor elements malfunction, the device generates error codes called “Engine...”.

The on-board computer State X5 M for Kalina also has a built-in display settings function. Using it, the driver can display on the device screen those indicators that are most important to him. Using the same option, you can adjust the color, contrast and brightness of the display.

Another one useful feature— “Diagnostics of the gasoline pump.” It controls the pressure and power of the system. This option also makes it possible to determine the condition of each Lada injector nozzle.

Indications BC Lada Kalina

• P0134 - no signal from the oxygen sensor;
• P0201 - damage to the injector control circuit;
• P0301 - misfires appeared in the cylinders;
• P0335 - no crankshaft sensor signal;
• P0560 - low voltage in the electrical circuit of the machine.

2 New device functions - what to expect from manufacturers in the future

3 Installing the device yourself - how to avoid mistakes

Every motorist should have a universal device for diagnosing his car.

You can read, reset, analyze all sensors and configure the car’s on-board computer yourself using a special scanner...

• instructions for connecting a computer;
• a set of new electrical wiring;
• screwdriver;
• double sided tape;
• soldering iron

First, disconnect the negative terminal from the Lada battery, then unscrew the 4 screws that secure the standard ashtray. We pull it out and find the block with the power contacts alarm. We take out the block - we will connect the on-board computer to it.

Next, take out the orange wire that is connected to the seventh pin, and instead connect the red and white wire from the computer. After this, we insert the orange wire into the single connector of the red and white cord. We disconnect the red-black cord from the tenth pin and instead install the red wire from the computer. Insert the previously disconnected black wire into the single connector of the red wire.

If the computer does not work, you need to pull it out and use pliers to strip the ends of the electrical cords. If grooves are formed during the installation process, they can be soldered using plastic or metal strips.

Do you still think that diagnosing a car is difficult?

If you are reading these lines, it means you are interested in doing something in the car yourself and really saving money, because you already know that:

• Service stations charge a lot of money for downtime computer diagnostics
• To find out the error you need to go to specialists
• The services use simple impact wrenches, but you can’t find a good specialist

And of course you are tired of throwing money down the drain, and driving around the service station all the time is out of the question, then you need a simple CAR SCANNER ELM327, which connects to any car and through a regular smartphone you will always find the problem, turn off CHECK and save a lot of money! !!

We ourselves tested this scanner on different cars and he showed excellent results, now we recommend it to EVERYONE! So you don't get caught Chinese fake, we publish here a link to the official website of Autoscanner.

Hello! I have a Lada Kalina. The check engine light is on, but everything works fine. There is error 4 on the panel. What does this mean and what could it be related to? (Vladimir)

Hello, Vladimir. The appearance of the CheyEngin icon is a common problem in all domestic vehicles with an on-board computer. Tips for solving the problem are given below.

[Hide]

What does error 4 mean?

Fault code 4 indicates that the refrigerant temperature control regulator is not functioning correctly. In most cases, this code lights up on the dashboard if it detects a break in the regulator wiring for 20-30 seconds.

1. After analyzing your problem, we turned to many sources on the Internet and consulted with the owners of Lad Kalin. As it turned out, the number 4 often appears on the instrument panel; this can be considered one of the most common errors in these vehicles. Replacing the antifreeze temperature regulator in the cooling system in some cases will help cause the error to disappear. However, according to most potassium growers, in fact, in most cases it does not give a good result.
2. If you believe the reviews of car enthusiasts, then such an error, as a rule, appears mainly during cold weather. If there are no signs of breakdowns, then perhaps you have no reason to worry.
3. It is likely that over time the vehicle has been used, the sensor itself has oxidized. As a result, bad contact, which does not allow signal transmission to normal mode. Sometimes this happens after you have washed your car. We recommend that you make visual diagnostics regulator - if you notice that the contact has really oxidized, then it needs to be cleaned.
4. If there is a continuity, if cleaning the contacts did not help, you need to ring. It is quite possible that the reason for the appearance of the code on the device is a broken wiring or short circuit. In the case of a break, it will be enough to replace the wires or eliminate the cause of the short circuit.

If you have changed the sensor, replaced the wire and cleaned the contact, but the problem still remains, we recommend that you perform more detailed computer diagnostics. IN domestic cars it often happens that when incorrect operation control unit, errors may appear on the screen that in fact do not exist. To understand this, you need to completely read all the codes from the on-board computer and then draw conclusions.

Video “Do-it-yourself diagnostics of a Kalina car”

To learn how to properly perform computer diagnostics at home, watch the video.

– this is the most frequent malfunction, which may occur in Lada Kalina. Sometimes, it is not possible to carry out diagnostics using a connection. The question arises: how to carry out diagnostics then? There is an exit. Not everyone knows, but car diagnostics can be done using the dashboard.

Video about ECU self-diagnostics using the instrument panel on a Lada Kalina:

The video materials will clearly show how to diagnose the Lada Kalina using the dashboard, and also contain some explanations and recommendations

Diagnostic process

Instrument panel with which you can perform diagnostics

So, diagnostic operations using the dashboard are not complicated and almost every Kalina car owner is able to cope with this on their own. Guided by step by step instructions described below, you can carry out diagnostics on any generation of VAZ 1117-1119.

Now let's move directly to the process of performing diagnostic operations:

1. We reset the daily mileage indicator. For this purpose, there is a special button on the instrument cluster.

   

   Using the daily mileage button we reset the indicator

2. Do not release the button and turn to position I.

   

   Insert the key into the ignition and turn to position 1

3. If everything is done correctly, then all the arrows on the instrument cluster will begin to move from the initial position (zero indicators) to the final ones.

   

   Instrument needles move from the beginning to the final control point

4. Using the button on the wiper switch handle, we switch the information screen.
5. First of all, the tachometer and sensors are checked for functionality.
6. In the second case, the version will be displayed on the screen software. Often, as practice shows, this is version 3.0 or 3.2.

   

   The instrument panel screen shows the software version (in in this case UEr 3.0)

7. In the third case, error codes that are present in the ECU will appear.

   

   Errors received during the diagnostic process. There are 8 and 4 errors in photo 6.

8. Now let's decipher the errors that can pop up on the dashboard screen:

Decoding instrument panel readings

2 - the on-board network voltage exceeds the norm;
3 - a fuel level sensor error has been detected. Occurs if there is an open circuit in the sensor within 20 seconds.
4 - an error has occurred in the coolant temperature sensor. Appears if an open circuit is detected within 30 seconds.
5 - a sensor error has been detected in the car outside temperature. If there are no sensor readings within 20 seconds, “-C” appears);
6 - detected;
7 - emergency oil pressure;
8 - error or malfunction of the brake system;
9 - low charge battery;

E- detection of an error in the data packet stored in the EEPROM.

Now all that remains is to compare all the errors that popped up on the screen with those listed above.

conclusions

As practice shows, diagnosing the Lada Kalina using the dashboard is quite easy and simple. This does not require special tool or skills. It is worth noting that, according to the experience of many car owners, it is not always possible to fully diagnose everything, since wear and breakage of some contact connections can be interpreted by the ECU in its own way.

VAZ Lada Kalina is equipped standard computer immediately at the enterprise. And he - quality brand, which has wide functionality and can satisfy many car drivers. But for those who want more, it is recommended to purchase a device with serious functionality, for example, the Gamma on-board computer.

It has much more functionality compared to in a regular manner computer. It displays and resets fault codes, and at the same time makes diagnostics. It is launched on the dashboard by pressing a key to reset the daily mileage, and at the same time turning on the ignition. After pressing the key, the firmware version of the on-board computer (BC) and error codes, if any, will be shown on the computer screen.

1. Most high voltage on-board network of the machine.
2. Error fuel sensor(for example, within 20 seconds it was discovered that the circuit was broken).
3. Error temperature sensor coolant.
4. The motor is overheated.
5. Oil pressure is in poor condition.
6. The brake system has broken down.
7. Battery low.

What should I do to troubleshoot? You should hold down the key and turn on the ignition, but do not start the car. The arrows on the dashboard will move and the lights will turn on. After this, you need to press one of the keys on the switch, which is located under the steering wheel. Then the arrows will be on initial position, the display will show errors.

Let's give advice to those who buy a used VAZ car - most drivers don't even think about the fact that there is an option for diagnosing and resetting Lada Kalina errors. And therefore, before buying a VAZ, you should run this option to find out everything about the past of the car you are purchasing. Modern Automotive industry- This is a very developed industry, it is almost always an excellent assistant to any car owner.

This does not depend on the make of the car; the presence of a BC is an excellent feature of almost any car produced in last ten years. Similar system VAZ is no exception. Many people know what an on-board computer is, but not everyone knows how to evaluate errors that have occurred and determine their meaning. Let's look at the above errors.

It should be noted that many of the errors characteristic of VAZ are understandable. For example, a temperature sensor error, the BC can issue it when the motor is cooled. But it happens that the computer gives an error falsely. For example, once the motor was overheated, the computer suddenly notifies about the error, even if there is none. That is, errors can occur if the BC remembers information about an overheated motor. And therefore, when this problem has been fixed, it is better to reset all BC readings.

And to fix it, you should press the Reset key - it is located under the control buttons of the on-board computer. But if the faults are not identified, you need to ask a professional for help. You should also pay special attention to the errors of the machine's bookkeeping system if it has already been used and was purchased secondhand.

Vehicle diagnostics and troubleshooting

If you nevertheless decide to buy a used car, then you should definitely make a diagnosis, paying attention to any Lada error codes that appear on the device display. Information about existing errors will be very useful, be sure to pay attention to this Special attention. To diagnose and find out information, you should contact a car service center if there is no special insert on the used car you are buying.

In fact, such a procedure is a huge list of information that can tell about any possible danger. Usually this is not given importance, but in vain. For example, if a car’s BC states that the airbags are faulty, you definitely need to check this. Correction: what needs to be done? Immediately press the left button and the right one, from this press the on-board computer adjusts the selected parameter.

Then pressing the keys left or right changes the parameters. After pressing simultaneously, you exit from the adjustment. Reset. By pressing the left and right keys simultaneously, the options displayed on the screen will be reset. If everything is done in the “System error” mode, after that the error disappears. If faults actually exist, the error will remain in memory until reset occurs.

If the BC does not turn on, the causes of the problem are:

• No electric current in BC connectors;
• there is no contact in the terminals.

BC cannot diagnose the reasons for this:

• the wire came loose;
• no contact.

BC cannot calculate the speed of the car, the reasons for this problem are:

• there is no contact in the connectors.

BC cannot calculate the remainder in the fuel tank, reasons:

• devices do not have software compliance.

The BC incorrectly shows how much fuel is left in the tank, the reasons for this are:

• there is no wire in the wiring at the 8th contact and the 9th terminal in the on-board computer;
• The car panel is showing incorrectly.

There is no BC screen backlight, reasons:

• I need to make the screen brighter.

The thermometer shows incorrectly, reasons:

• the wire has broken in the temperature detection sensor;
• incorrect contact with the on-board computer.

• speaker is faulty;
• the software has crashed;
• The voice accompaniment is not reproduced (you must press the “up” key and hold it for more than three seconds).

BC writes incorrectly, the program has gone wrong, etc., reasons:

• The on-board computer is not connected or there is no contact with it;
• there is no contact in the connected battery terminal (the contact should be securely fixed).

Initialize the BC:

• previous settings will be reset;
• reset all parameters for the previous ride;
• set the clock to 8 hours 00 minutes;
• The alarm clock should be at zero, its notification is disabled.

Diagnostic mode regular Lada can be started on the instrument panel by pressing the daily mileage reset button and at the same time. After this, pressing the button on the windshield wiper lever will cause you to see the version and error codes, if any, on the display.

Error codes Lada Kalina

1. extremely high voltage
2. fuel level sensor error (if an open circuit in the sensor circuit is detected within 20 seconds)
3. temperature sensor error
4. incorrect operation of the outside temperature sensor
5. overheating (the criterion for triggering an acoustic signal has been met)
6. emergency oil pressure
7. breaking
8. critical discharge

I would like to say a few words about the most common Lada Kalina, which the author of the presented video recorded in the process of diagnosing CD. Error under code "4", the most common and almost always appears when the engine is not warmed up, also if the fuel level light in the tank lights up. Error under code "6", indicates overheating a. Error under code "8", could be recorded in the computer memory due to insufficient level brake fluid.

After identifying errors, you can reset them by pressing and holding the vehicle's daily mileage button.

And in conclusion, a little advice to the buyer of a used car. Many car owners are not aware of the presence of a function for diagnosing and resetting errors on the on-board computer. Therefore, before purchasing, it is recommended to run this function and thereby find out the past of the car you have chosen.
