How to connect the State on-board computer to a VAZ 2110 (instructions)

With the advent of more modern technologies, domestic cars began to be equipped with on-board computers. The VAZ 2110 model was no exception.

Thanks to the on-board computer on the VAZ 2110, you can check for yourself what condition the car is in, what problems have arisen and how to solve them.

Features of connecting the VAZ 2110 on-board computer

If you have already decided or, moreover, purchased an on-board computer for your ten or another modern model of a domestic VAZ car, then the time has come to install it.
For those who are just thinking about buying a BC, we recommend that you read the previous article on choosing an on-board computer for a VAZ. Installing an on-board computer is not difficult and will take you half an hour. As a rule, the BC package already includes a contact block with the help of which connection is made to a special connector of the car. For those who don't know, the socket is located on the lower right side of the torpedo.

For additional information, a few words about the pinout of the connector for connecting the on-board computer .

As you can see, in the image shown, after connection, the on-board computer has access to all the main elements of the vehicle’s electronic on-board network. To fully launch the BC, all that remains is to connect the K-line.

What is a K-line and why is it needed?

The K-line is the channel through which the most important information is received by the bookmaker. Using this connection, data on errors that occur during engine operation, as well as its temperature, and other important diagnostic information will be available. The K-line wire is connected to the main connector, which is located under the steering column to the left of the driver's seat. Using a special wire, which also comes with the on-board computer, we make the connection as shown in the image shown.

And finally, about the diagnostic connectors of the VAZ 2110. In total, there are two types of contact blocks Euro-2 (GM) and Euro-3 (ODB-II); the photo shows the pins to which the K-line must be connected when installing the on-board computer on the VAZ 2110 .

The process of diagnosing an ECU using a special scanner.

Electronic control units of the VAZ-2110 are the main tool for controlling and automating most processes in the car. To adjust the software, they often resort to replacing the “brains” with more “flexible” ones and reflashing the ECU.

First of all, it is necessary to clarify several terms that will be required when considering questions about changing the electronic control unit:

• Wiring compatibility . To replace it, the connectors on the old ECU and the new one will need to match.
• Software is a predetermined algorithm that can change depending on the needs or desires of the motorist.
• The hardware component is the electronic control unit itself, boards or other components that allow the systems associated with the ECU to function normally.

For the VAZ-2110 family there were two types of connectors. So, for the “brains” January 5.1.x, Bosch M1.5.4, Bosch MP7.0, and VS 5.1 there was a 51-pin connector, but for January 7.2(+), Bosch M7.9.7(+) and M73 - 81 -pin.

That is, the interchangeability of control units is caused by the pinout of the unit.

ECU January 7.2.

Differences

Fundamental differences between 81-pin blocks and blocks of previous generations:

1. Overall body dimensions and weight have been reduced.
2. New, more modern connectors with improved connection reliability.
3. The controllers have built-in switches, therefore, instead of ignition modules, ignition coils can be used, which increase the reliability of the ECM as a whole.
4. There is no software or hardware compatibility with any of the previously released units.

Even electronic control units from the same manufacturer will differ significantly in pinout. Therefore, the interchangeability of the “brains” will depend on the number of connector pins. Also, it is worth understanding that the firmware will play a big role. When changing the ECU, the motorist will have to reflash the unit for the correct operation of all vehicle devices.

ECU January 5.1.

A very important nuance remains that the software of the control unit must be compatible and comply with the type of injection, as well as the toxic standards laid down by the manufacturer.

Installing the Multitronics X10 trip computer

When purchasing this item on Avito, of course, there will be nothing else in the kit except the BC. Actually, the ambient temperature sensor and the wire to the diagnostic block had to be farmed myself). There were no problems with this)

1. Take out the standard clock and disconnect it from the connector. We release the connector and it flies far and for a long time into this abyss of wires)). Next, roll up your sleeves, lower your hand into the resulting hole and feel for the standard BC block.

3. Now it is necessary to make a temperature sensor, because a used MK will not have one, the percentage is 100%) The sensor itself was the LM335Z chip.

Microcircuit in TO-92 package. It has 3 pins, the leftmost pin, if you look from the side of the marking where the edge is cut off, we don’t need it, personally I just broke it off) Barbarian, yes))

Next, take a 2-core wire and a soldering iron and begin the soldering process. I was a little lucky, and in my case, the BC included a 2-wire wire with a connector for the computer.

Solder the black wire to the rightmost leg of the sensor, the wire with a strip (red or white, depending on what you have) to the middle leg. Then we take a beautiful green heat shrink and isolate the sensor from the aggressive environment.

Then, after everything done above, we connect the sensor with a wire under the beard, then I thought about where to pull it. Selected the engine compartment. The exit to the engine compartment was made through the clutch cable seal. Next, I brought the sensor along the ties to the tow hook and fixed it there with a very beautiful yellow tie)

4. Take the trip computer, insert the pads into it and begin to figure it out according to the previously downloaded instructions from the official website)

Personally, I found the management of the bookmaker to be a little difficult, although I have now completely understood its functionality and am happy with everything).

The BC itself will determine your ECU. Plus, you will also need to make adjustments to the temperature sensor in order to achieve accurate temperature readings overboard. You can then begin on-screen programming and setting maintenance counters.

In general, I am very pleased with the work of BC. I saw what I wanted to see. I was a little upset, but more about that in the next blog.

Good luck to everyone) If you have any questions about the On-Board Computer, I will be happy to answer them.

Connecting Orion bk 16

I got some brotherly encouragement

, I’m not happy anymore, I’ve been scratching my head on how to connect it.

What is this anyway? Can anyone tell by appearance? Or how can I understand whether it is BC 16, BC 17 or BC 46

his mother?! His name is 2115-3857010 Or just connect it to the power supply and at the beginning of its switching on it should tell you who he is?

In general, on the Internet you will find a lot of comprehensive information on connection - I agree! But there is one thing! Now I will try to describe this to you But. The photo of the connection was taken from the Internet.

And if you connect a K line to it, then what? Will it be connected to ground or something?

Who can tell me what kind of stray thing I have? Maybe this is for a carb engine, I have an injector.

From the photo you will hopefully see what I want to say. There are no more wires, except for those that come out of the BC itself and I have a 9-pin block there. I don’t really know what to do, help people out.

Not long ago on Sunday, a few thoughts appeared: 1.

It’s a pity to give away money for identifying the reasons for the Check Engine light (suddenly you’ll have to buy something else with it) 2. Somewhere in Styopka’s friend there’s a bookmaker in his four that “blocks the hole in the wall”—it’s not working. 3. It’s not for nothing that I received a radio tower)

I call Styopka, explain the situation, like, let me try to revive him, give him a ride, test him, then we’ll give you a B, etc. Since my friend is a little far from electrical (though I’m not a genius myself, but I’m trying to figure it out), and there is a desire to fix the thing, the go-ahead was received almost immediately.

So, a visual inspection showed that this is an Orion BC, model #16. He came to me in the following form.

I started looking for information on it on the Internet and sorted it out along the way. As it turned out, there are new and old BK-16 models. The difference is in the firmware, in the types of screens, and in the presence of a mini-USB port inside the case.

Also, there must be a special adapter from the block located on the BC (13pin) to the block, which is hidden under the panel (9pin). The difference is in the photo.

Connecting the VAZ 2110 on-board computer. How to install the on-board computer

If you have already decided or, moreover, purchased an on-board computer for your ten or another modern model of a domestic VAZ car, then the time has come to install it. For those who are just thinking about buying a BC, we recommend that you read the previous article on choosing an on-board computer for a VAZ.

Installing an on-board computer is not difficult and will take you half an hour. As a rule, the BC package already includes a contact block with the help of which connection is made to a special connector of the car. For those who don't know, the socket is located on the lower right side of the torpedo.

For additional information, a few words about the pinout of the connector for connecting the on-board computer .

As you can see, in the image shown, after connection, the on-board computer has access to all the main elements of the vehicle’s electronic on-board network. To fully launch the BC, all that remains is to connect the K-line.

What is a K-line and why is it needed?

The K-line is the channel through which the most important information is received by the bookmaker. Using this connection, data on errors that occur during engine operation, as well as its temperature, and other important diagnostic information will be available. The K-line wire is connected to the main connector, which is located under the steering column to the left of the driver's seat. Using a special wire, which also comes with the on-board computer, we make the connection as shown in the image shown.

And finally, about the diagnostic connectors of the VAZ 2110. In total, there are two types of contact blocks Euro-2 (GM) and Euro-3 (ODB-II); the photo shows the pins to which the K-line must be connected when installing the on-board computer on the VAZ 2110 .

Troubleshooting BC

Malfunctions occur with BCs of various modifications. It would be useful for the owner to know what to do in such cases. Many failures occur when the on-board computer was not installed properly. First, you need to check the reliability of the connections. Secondly, there is a high probability of accidental damage or pinching of the K-line. Multitronics itself will report this, displaying obviously incorrect data.

You can deal with the problem yourself. If it is connected to a damaged K-line, then you need to purchase a new wire for the VAZ-2111 at a car store or on the market.

It is inexpensive, and the entire replacement procedure will take no more than 60 minutes. More time will be required if the problems of the on-board computer 2110 are caused by broken contacts. It is necessary to disconnect the device after performing a visual inspection. If bent plugs are still present, you should select new ones from the store and resolder them.

Using the BC on a VAZ passenger car allows the owner to always be aware of the technical condition of the car. The device is selected based on needs. Its effectiveness depends on correct installation.

Many owners of domestically produced cars, including the VAZ-2110, are trying in every possible way to improve their cars. And if cutting off an extra coil from the rear springs or screwing a “bench” onto the trunk lid is nothing more than “collective farm tuning,” then installing an on-board computer is a completely justified step. An on-board computer is a useful tool with which you can track engine operating parameters, current and average fuel consumption, speed and other equally important information.

How to calibrate the FLS on a standard BC

An important parameter is the fuel level in the tank. For the sensor to work correctly, it must be calibrated. For this:

So that after installing the VAZ-2110 on-board computer, it notifies you that the maximum permissible speed is exceeded, you also need to carry out “training”. To do this, switch to the average speed input mode and hold the button (top right) for several seconds. To enter an integer number corresponding to the speed, you need to use the “” “–” buttons on the front panel of the device.

Disadvantages of injection systems

Among the negative qualities are the following:

1. The on-board computer “State” of the VAZ-2110 provides complete information, but it is inconvenient to perceive it. The display is located to the side, under the tape panel. Therefore, in order to consider any data, you will need to stop.
2. A very expensive catalyst, located literally 10 cm from the road surface, is easily damaged. Repairing it is not always possible, and the cost is very high. In the event of a breakdown, not only fuel consumption will increase, but also the level of CO in the exhaust.
3. Initially, only carburetors were installed on the “ten” engines. Later, the engines were sharpened for the installation of injection systems. Consequently, dismantling some sensors and devices turns out to be problematic due to their inconvenient location.

Block for connecting the trip computer (BC, in my case the device is Multitronics SE-50).

VAZ cars of the tenth family have a standard connector for connecting the on-board computer to the car. That is, to install the BC, everything is already provided by the factory, this is the first thing that is needed. The second is connecting the control line from the electronic control unit to the trip computer. Connection is carried out according to the following instructions:

Connecting the K-line and assigning contacts to the BC block

Types of diagnostic pads

Some of the wires of the trip computer connector had to be restored because they were torn out; it was not originally installed in the car.

The automatic switching on of the interior lights was implemented through the on-board display unit, but it is now missing. Therefore, to preserve this function, it is necessary to connect the following contacts according to the diagram:

Self-installation of BC

After purchasing a suitable device, you need to connect the purchased equipment. For the bookmaker to function, you will need:

• DC voltage source +12V (usually a car battery performs this function).
• The power supply supplied to the BC at the moment the key is turned in the ignition switch. Thanks to this, the BC will turn on simultaneously with the start of the vehicle engine.
• Voltage when the side lights are turned on. Thanks to it, the BC will automatically adjust the screen brightness and reduce it when the dimensions are turned on. This will also reduce battery consumption.
• Weight.
• Signal from the fuel level sensor. Many modern bookmakers cannot do without it. This is due to the fact that the computer needs sensor data to automatically calculate the level of fuel consumption.
• Diagnostic lines (K-line). The channel is responsible for providing information about all car systems.

On some older models, a diagnostic block with signals is not installed. In order to obtain a voltage of +12 Volts, you will need to supply power to the BC from the ignition switch, and connect the side lights to the cigarette lighter. The mass can be taken from the body or from the cigarette lighter.

IMPORTANT! Before carrying out work on connecting the battery, you need to turn off the power to the battery.

To connect the BC to the fuel sensor, you need to carefully study the electrical circuit of the vehicle. Thanks to this, you can find the right cable to connect. Afterwards, all that remains is to decide on the connection location and connect the wire from the BC there. K-line is usually located on the diagnostic block. “Euro 2” connectors are equipped with them in socket “M”, and in “Euro 3”, in socket “7”.

As a rule, a temperature sensor is included in the standard configuration of the BC. It must be installed outside the vehicle. The most common location for attaching the device is the left side of the bumper. This way, the device will not be exposed to any unnecessary heat. Well, the wire from the sensor is routed into the holes between the engine compartment of the vehicle and the passenger compartment.

As for the installation time of an on-board computer on a car, it takes no more than 1–2 hours, but at the same time, it allows you to significantly save money (for example, the average cost of installing an on-board computer is 50 US dollars).

instruction manual on how to connect and configure the BC

The VAZ-2110 on-board computer is used to control vehicle systems. In its original configuration, the car leaves the factory without a smart gadget, but this does not prevent the driver from purchasing it. Before this, it is necessary to evaluate the technical characteristics of the models on the market. Each of them is designed for specific operating conditions of the VAZ-2111, 10 or 12.

Functional purpose of the device

The development of the technical component of vehicles has led to an abundance of electronic and mechanical devices that control the operation of the car. Each of them reflects one or another indicator, which a person does not always have time to analyze. This is where the VAZ on-board computer will help, taking control of what is happening. In addition to monitoring the operation of vehicle systems, it will promptly inform the owner about a failure.

Another advantage is that the standard on-board computer analyzes the technical condition of the car within the specified parameters. In practice, this means that the driver can ask a question regarding the presence of components or assemblies whose performance exceeds the technical norm. Preventative analysis reduces the likelihood of downtime due to technical failure. The VAZ trip computer differs in the available options depending on the configuration:

Installation recommendations

The efficiency of the device is determined at the stage of selection and subsequent installation. An on-board computer (BC) is selected for the VAZ-2112, which collects and analyzes incoming information. Regardless of the model, it is equipped with a Check Engine light. When it is triggered, the bookmaker will independently determine that it is not working.

Features of the models

As mentioned earlier, on-board computer models vary depending on their application. So, narrowly focused ones are divided into:

• Trip computers

On-board computers of this type allow you to plot the route of the vehicle. Features of the device include the ability to automatically determine coordinates and full navigator functionality. Additional indicators include information about travel speed, fuel consumption and weather “overboard”.

• Control computers

Designed to control electronic systems. They allow you to manually regulate the operation, starting from the fuel dampers of the power unit and ending with the climate control system.

• Diagnostic computers

The device is also called a service computer. It is intended for troubleshooting the vehicle. It is important to note that an on-board diagnostic computer is quite rare. The functions of this device can be equipped with universal on-board computers. As for the functions of the service BC, these include: Monitoring the status of the vehicle's electrical supply devices. Allows you to identify problems such as short circuits, overvoltage, malfunction of car sensors and lighting devices, and electrical leaks. Monitoring wear of brake pads and discs. Oil and coolant level monitoring. Diagnostics of the performance of all vehicle systems. The ability to save received data has been implemented.

Important! In addition to the above, the device is capable of storing information about the occurrence of certain problems. Afterwards, based on the information, a special report is generated, which provides information about the performance of the vehicle systems, and the report also provides recommendations on systems that require repair.

We connect the on-board computer to the VAZ-2110 with our own hands

Many car enthusiasts have encountered the problem of connecting an on-board computer. The change procedure may require some knowledge and skills, but it is realistic to do the operation yourself, with your own hands.

Video about connecting the on-board computer to the VAZ-2110

The video will tell you about choosing and connecting the on-board computer. And also, he will tell you about all the subtleties and nuances of the procedure.

Final installation

Make sure all electrical connections are made securely. It is advisable to solder the wires and then insulate them. Pull the harness through the interior of the console to the installation site of the BC. After this, you can connect to the wiring from the fuel level sensor in the tank.

After dismantling the dashboard, you will have access to the electrical connection terminals. You need to remove the pink wire from the gray block; it is located in the harness. Connect it to the on-board computer. To check the device, you need to connect the negative terminal and turn on the ignition.

Choice of "Brains"

AvtoVAZ Lada 2110 cars have been equipped with several electronic control units throughout their production history. Thus, the following ECUs can be found on vehicles:

According to the experience of motorists and the recommendations of specialists, it is best to take electronic control units marked Bosch MP7.0, January 7.2+ and January 5.1.

If you have to change the remaining blocks, it is recommended to take an ECU with these markings, since they are more “flexible” for changing the software.

Setting an alarm

• Press button 4 in Alarm mode.
• Use buttons 5, 6 to set the desired hour value.
• Press button 4. Use buttons 5, 6 to set the desired minute value.
• Press button 4 to complete the alarm setting.
• In the “Current time” mode, the alarm symbol will light up (the alarm is on).

* If the counter of any of the accumulated parameters (“Travel time”, “Travel time with stops”, “Total consumption”, “Trip mileage”) overflows, all accumulated ones, as well as calculated ones (“Average fuel consumption”, “Forecast”) are reset mileage on remaining fuel", "Average speed") parameters, with the appearance of a two-tone sound signal.

Turning off the alarm

• Press button 4 in Alarm mode.
• Press button 1 to turn off the alarm. “—.—” will appear in the digital digits, and in the “Current time” mode the alarm symbol will not light up (the alarm is turned off).

Adjusting the brightness of the indicator backlight

When the side lights are on, the illumination level is adjusted using the instrument scale illumination regulator. When the side lights are turned off, the backlight level is adjusted by software:

On-board computer diagnostics

Faulty sensors can be determined using ECU diagnostics.

To identify faults in the electronic control units of the VAZ-2110, diagnostic equipment is used. Usually they use a tablet or laptop with special software. Also, the motorist, if the operation is performed independently, will need a special OBD II cable.

The process of diagnosing an ECU using a laptop.

Diagnostics are carried out to determine errors in the electronic control unit and troubleshoot problems in on-board systems, especially on engines. After identifying the error, it is necessary to decipher and find the cause of the malfunction in order to eliminate it.

Correct operation

With the right approach, the installed BC will not cause problems.
However, if it shows unreliable information, then it is worth removing the on-board computer and checking it for serviceability. How to remove the device is clear. After all, it has a disconnectable connector, so you need to dismantle it in the reverse order. The main thing to remember is that this is a fragile thing and can be broken. After dismantling, you should check the integrity of the soldering and wires and eliminate any breaks . Afterwards, put the device where it was before and use the working device again.
