Difficulty of the material:

For fans - 3 out of 5

To carry out diagnostic operations on the “Ten”, including for flashing the ECU, you need to know the location of the service connector for connecting equipment (adapter, programmer, auto scanner). This material provides all the necessary information.

For VAZ 2110, the type and configuration of the connector depends on the year of manufacture, engine and ECU type:

Where is the diagnostic connector for the VAZ-2110?

VAZ 2110 with a “European panel”, the diagnostic connector is located at the bottom right of the steering column. The block is closed with a decorative cover.

12-pin connector: All injection models were equipped with this, except for individual assemblies after 2002, which had an OBD-II connector installed.
16-pin connector: This was equipped with some models released after 2002, which were equipped with BOSCH MP7.0 Euro-3, BOSCH M7.9.7, January-7.2 control systems.

The location of the connector is indicated in the diagram in position No. 3. The following are also visual photos of the diagnostic block.

About the ECU and its location is written in the article “Diagnostics of the VAZ 2110”. The following shows the pinout of the OBD2 and OBD1 connectors, as well as the assignment of the contacts of some electronic control units that were installed on the “Tens”

Connector type No. 1—16-pin OBD-II connector in the shape of a trapezoid:

Brands and years: some models after 2002 with control systems BOSCH MP7.0 Euro-3, BOSCH M7.9.7, January-7.2, January-7.3.

Connector type No. 2 - 12-pin rectangular connector: Make and year: all injection models, except for some models after 2002 that have an OBD-II connector

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.

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 .

Instructions for performing diagnostics

To diagnose a VAZ, a computer or diagnostic equipment is connected using a diagnostic connector.

Computer diagnostic socket

All broadcast codes are read by the scanner. They are stored in the controller’s memory until its power is turned off. Using special software, specialists decipher the codes and determine what malfunctions and failures exist in the system.

The diagnostic procedure consists of several stages:

Suspension diagnostics. This procedure is performed if uneven tire wear, knocking or humming is detected when driving at a constant speed, making sharp turns, or on an uneven road. And also in case of premature activation of the ABC, increased free play of the steering wheel.
Engine check. The power engine should be diagnosed if it runs intermittently, takes a long time to heat up, is difficult to start, as well as with increased fuel consumption, loss of power, the appearance of extraneous noise, or a decrease or increase in idle speed. During diagnostics, the electrical supply and ignition system are checked, and the pressure in the cylinders is measured (the author of the video is Pavel Master).

An automatic transmission is diagnosed in the following cases:

no gear is engaged;
When changing gears, noises, jerking, and slipping appear;
increased fuel consumption;
Oil leak detected.

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:

Empty the fuel tank completely.
Switch to mode to select the fuel type. To do this, press and hold the first top button in the right row. The display will show "0".
To switch to tare mode, you must press and hold the button with the car on it. The on-board computer on the VAZ-2110 will emit a short signal.
Fill the fuel tank with 3 liters of gasoline.
After a few seconds, press and hold the car button again. The on-board computer display should indicate that there are 3 liters of fuel in the tank.
Gradually fill the tank and press the button after each addition.
After maximum filling, the on-board computer will turn off - this completes the calibration.

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.

Other diagnostic methods

If you don’t have a scanner or laptop at hand, you can conduct a mini-diagnosis. To do this, you need to hold down the odometer button (located on the dashboard). At the same time, the ignition is turned on. After which the button is released. At the same time, the instrument needles begin to jump. Next, press the odometer once. The display will show the firmware number. You should press and release the button again.

This way you can see the two-digit error code. However, it should be noted that not all faults can be diagnosed in this way. Therefore, this does not replace a full diagnosis.

Conclusion

. Engine management problems are not uncommon. Therefore, the skill of independently diagnosing problems will not be superfluous. To do this, you need to know the error codes for VAZ 2114 and 2115. You will also need a scanner or laptop with the program installed. There are usually no difficulties with using this equipment.

The topic of this article will be diagnostics of the tidy on the VAZ 2110, 2111, 2112.

In order to start the self-diagnosis mode of instrument clusters, you must turn on the ignition while holding down the button that resets the daily mileage.

How to understand that the mode has started? Everything is very simple, the oil pressure lights, the battery icon, the fuel warning light and the Chek light will start to light up. In this case, all arrows begin to move from the initial position to the maximum, and this process is repeated. This way you can check the operation of all light bulbs, instruments, and arrows.

When we press the button to reset the daily mileage, an error code will appear.

To reset this error, you need to press and hold the button that resets the daily mileage. Until the error resets to 0.

To check that the errors have been reset, we repeat the procedure: enter the mode - diagnostics of the VAZ 2110 device (while turning on the ignition, press and hold the button that resets the mileage); Press the mileage reset button three times and look at the on-board screen. It should show 0.

We decided on this. But now we need to find out what kind of error we identified during the self-diagnosis of the instrument clusters. A table is presented to you for this purpose.

If the number is different, for example, like ours, this means that there are several errors and the computer shows their sum: 6 (2+4), 10 (2+8), 12 (4+8), 14 (2+4+ 8).

You can watch the whole process in the video below:

We sorted out the errors during self-diagnosis of the instrument clusters of the VAZ 2110, but here you can see (when the engine light comes on) for yourself.

The desire to improve the cars they produce led the engineers and developers of the Auto VAZ concern to the idea of the need to introduce such an innovation as an on-board computer. Its purpose is to identify vehicle malfunctions and report them in coded form.

But in order for the car owner to independently figure out what the problem is, he will need to know how the codes are deciphered. It makes sense to consider the issue in more detail, using one of the VAZ models.

on-board computer VAZ 2115 with your own hands (step by step)

To detect the reasons why the on-board computer issues error codes, diagnostics will be required.

This can be done in different ways:

contact the specialists of a specialized service station
try to diagnose it yourself

If it is necessary to independently carry out diagnostics, owners of VAZ2115 cars will be able to follow the recommendations containing a list and procedure for all actions:

find the odometer button on the instrument panel and hold it down, then you will need to turn the ignition key to position “1”
The odometer button can now be released
this action will cause the arrows on the dashboard to move after pressing the odometer button again, a code will appear on the speedometer, which indicates the version of the standard firmware of the on-board computer
By pressing the odometer button a third time and returning it to its original position, we get a fault code.

What do error codes look like when diagnosing yourself?

This will be a two-digit combination of numbers; when performing diagnostics using professional equipment that service stations are equipped with, the combination will consist of four numbers.

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.

Ready connector BC

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:

Practical recommendations regarding choosing an on-board computer

VAZ 2110 on-board computer block

Objectively, it is necessary to understand that the quality and efficiency of a car’s on-board computer directly depends on its market value. From a practical point of view, the best way to choose an on-board computer is the advice of friends of motorists who have previously purchased one.

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:

Carburetor is a budget option that does not have sufficiently wide functionality. Installation does not take much time, and operation is simple. It is difficult to find it on the market due to low demand among VAZ-2110 owners.
Injection - there are various options on the market that take into account the needs of drivers. Among the main advantages is the ability to conduct in-depth diagnostics. For example, if the car does not start because the injector has failed, the system will notify you in advance. The cost of the on-board computer depends on the configuration.
Universal - installation is carried out on a VAZ-2111, 10 or 12 without taking into account technical specifications. Installation is carried out behind the rear view mirror or windshield.
Adapted - selected taking into account the make and model of the vehicle. Installation is carried out in a strictly designated place, which the instructions will help you find.

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.

Experienced drivers do not advise overpaying for sensors of humidity and outdoor temperature levels, a chronometer, and an alarm clock. These indicators are easy to obtain using a standard VAZ-2110 thermometer. Once the driver has made his choice, installation can begin. First, you should study the passport supplied with the device, which will tell you how to connect the on-board computer.

When operating a vehicle, only 1 BC is required. The presence of a second computer in most cases provokes failures in the operation of both systems. Connection to the VAZ-2112 is carried out via a 9-pin block. It is located behind the BC and has a trapezoidal shape.

A diagram of the vehicle and the on-board computer itself will help you connect the contacts correctly. To connect to the VAZ-2110 in the standard BC, contacts No. 10 and No. 11 are not used. They are intended for temperature, humidity and pressure sensors. The installation of the BC is completed by connecting the K-line. Mistakes cannot be made, otherwise the indicators obtained from the VAZ-2112 will be inaccurate.

The connecting line runs in the diagnostic block provided for it. When checking valves and other preventive inspections at a service station, it is into the block that the technician looks into the block to connect the equipment. When laying the cable, you should make sure that there are no bends and that it is close to moving elements. For example, when operating a vehicle, the K-line can be damaged by the gas pedal.

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.

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.

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

Soulemil › Blog › Crankshaft position sensor VAZ 2110 - how to find a fault and replace it?

A modern car consists of many parts, each of which performs its own important function. Information about the condition of the engine and other components is transmitted by various sensors, but the VAZ 2110 crankshaft sensor performs work that is unusual for these devices. Purpose of the VAZ 2110 crankshaft position sensor Crankshaft position sensor

If the engine of a 9th or 10th series car refuses to start, any driver immediately begins to check the power and ignition system, and when it comes to contacting a car service center, they say that the DPKV has failed (this is what the abbreviation for the full name of the sensor looks like ). The bewilderment of car owners is dispelled when they find out that this is the only sensor without which the engine will not work.

The crankshaft sensor of the VAZ 2110, as well as on many other cars, does not perform a monitoring function, but synchronizes the phases of fuel injection and supplying an impulse to ignite the combustible mixture in the combustion chamber

Obviously, removing such an important attribute from the design makes it impossible for all systems to work harmoniously

In its operation, the sensor uses the principle of electromagnetic induction, and reads the necessary “information” from the generator drive toothed pulley, in the immediate vicinity of which it is installed. Disconnect the sensor Unscrew the mount Remove the sensor VAZ 2110 crankshaft sensor - faults and their diagnosis Crankshaft position sensor bracket

Considering that the role of the DPKV in the operation of the engine is very significant, in the event of its malfunction, a variety of “surprises” can be expected. A completely failed sensor will definitely prevent the engine from starting. Other manifestations of sensor problems include:

unstable operation of the engine at idle; decrease in power; increase and decrease in the number of crankshaft revolutions (spontaneously); detonation when the load increases; intermittent starting.

For a device such as the VAZ 2110 crankshaft sensor, faults come down to two types:

damage to the windings and parts of the sensor itself; violation of the integrity of the wire and the quality of connections in the circuit.

The PCV sensor itself is very simple in design and rarely fails. A crankshaft position sensor error or breakdown can be caused by reasons such as: manufacturing defects, mechanical damage, significant contamination. The first two reasons do not depend on the driver, and the car owner can monitor the cleanliness under the hood.

In addition to the fact that the engine compartment is always under the influence of many destructive factors, such as temperature changes, small stones and dust flying from the roadway, significantly adding to the problems of oil leakage. If it is discovered that there is a leak of engine oil in any place, especially in the area where the sensor is installed - on the oil pump body, it must be repaired immediately. The contacts of the sensor wire connections must always be clean and protected. The wire insulation should not be damaged or have exposed wires. How to check if the VAZ 2110 crankshaft sensor is working?

Considering that a crankshaft position sensor error or complete failure has very similar symptoms to many other breakdowns, you should understand how to check its condition. You can only verify that the DPKV is working if you remove it. This is not at all difficult to do, you just need to follow these steps:

turn off the ignition; remove the terminal connector with the wire from the sensor; unscrew the only screw holding the sensor to the oil pump cover; remove the sensor.

To check, you need to have an ohmmeter and check the resistance of the windings. If the instrument readings differ from the required 550-570 Ohms, it means the crankshaft sensor is faulty. You should not try to repair it, as this device cannot be repaired. The only way out of the situation is to replace the crankshaft sensor of the VAZ 2110. The cost of the DPKV is low, installation does not require much time and skills, especially since the car without it still remains motionless. If the device shows that the resistance of the sensor windings is normal, then the breakdown should be looked for elsewhere. How to replace the crankshaft sensor?

Installation, as well as removal of the PCV sensor, is done quickly and without difficulty. Before proceeding with installation, the installation site should be cleared of dust and dirt. Next, simple steps are performed: the new sensor is inserted into its regular place; the fastening screw is tightened; The connector with the wire is put on. At this point, the replacement of the VAZ 2110 crankshaft sensor is completed and you can start starting the engine.

Lada 2110 Green Arrow › Logbook › Do-it-yourself diagnostics using the K-line, part 1

Aleksandr Matskovich, 29 years old I drive Lada 2110 Green Arrow Kryvyi Rih, Ukraine

Good day to everyone who is reading this entry! And so I’ll start with the fact that I don’t have an on-board computer, I have a desire to install it, but more on that later. There was an interest in identifying my car with my own hands. In one of the previous articles, I wrote that after a rainstorm I filled up the air flow sensor, the check light came on and I went for diagnostics: they charged me 100 UAH. Within 30 seconds, having discovered that the sensor does not work, it needs to be replaced. I don’t need professional diagnostics; if necessary, I’ll go to a diagnostician, and for easy diagnostics, I decided to buy a K-line scanner

VAG-Com 409.1 K – Line scanner

oh, and even though my car is from 2004, it is 1.5l and 8kl with EURO-2, and is equipped with an ODB-1 connector. I googled it: it turns out that ODB-2 was already installed but on 16kL cars with EURO-3 from earlier years. I also had to buy an adapter with

Adapter OBD-II 16pin to GM12

I ordered everything from the online store, along with the cords I received a disk with programs for diagnostics and a bunch of different information on diagnostics. I configured all the com ports on the laptop and went into the garage with the laptop to try. I plugged it in, turned on the ignition, bam, and the fuel pump immediately began to hum without stopping. Naturally, nothing happened and I abandoned the matter (and this was last year at the end of autumn). Well, it’s already warm - there is a desire to resume this business. When I rang the adapter, I didn’t really understand anything, one rings 3 at a time, some don’t ring at all, I decided to redo it all. As you know, for diagnostics via the K-line you only need 3 wires (channels): 1) potassium itself 2) +12V 3) -12V aka ground, ground

I would like to note that in the figure above the contacts on the adapter are drawn as they should be, and not on the adapter or block! So imagine applying the adapter and think about where the contacts on the adapter and block should be, here is the picture below

location of K-line contacts on the blocks

Lamaaat adapter! Well, what can you do, the design is not collapsible (breaking the connector turned out to be not an easy task))) the black body is very hard, everything inside is still filled with white plastic. 4 wires are soldered, everything is called where which goes to the adapter where is the K-line, +12 and ground, the fourth, judging by the continuity, is the L-line, which we do not need. I’ll connect these 3 wires directly to the diagnostic block and try to connect to the ECU again! Good luck for me! Read the continuation!

Price tag: 300 UAH

Most often, the solution to the problem really lies in breaking the K-line wire. That is, the wire has simply moved slightly out of the block (the APS block of the immobilizer, or the BC block) and there is no longer any contact. If you have checked all the contacts, but the on-board computer still does not see the K-line wire, then you can proceed as follows:

2) If on your VAZ the connector with the APS is disconnected, then check for the presence of a jumper in the APS block between pins 9 and 18.

3) The problem may be in the immobilizer (the K-line signal comes, but disappears after the immobilizer). Check for the presence of a K-line on pin 18 of the APS block. Using the same method, you can check whether there is a break between the APS block and the BC block.

4) Interference or broken wire. Try replacing the wire from the BC to the diagnostic connector with a new, shorter one.

You can also check the k-line in a service center using computer diagnostics, or by connecting a known working on-board computer to the car (see how to connect a BC). And if the k-line does not work and at the same time there are problems with starting the engine, then start checking additional VAZ fuses.

break to the line VAZ 2110

First things first: 1. Three or four months ago, the check light started to light up from time to time, BC (State) gave the error K-line break. I worked closely on the car, changed a lot of things after the purchase, but I never got around to electrics, I confess.

The battery drains very badly, to the point that it is impossible to start the car in the morning, the relay clicks, but the starter does not turn. Sometimes it happens that the alarm does not go off, but the battery still goes to zero. So it goes.

The last few days I have been disconnecting the battery at night so that I am not late for work in the morning. I understand that I need to go to the station and carry out diagnostics. But work, time, money.

Things are like this. Yesterday I stopped at a gas station, stood in line, and turned off the engine. When it was time to start - FUCK! I turn the key to the first position,

Any modern car is equipped with a standard on-board computer - a device that allows you to obtain basic information about the functioning of all components and mechanisms of the vehicle. In addition, the on-board computer allows you to control additional car options, such as a multimedia center, air conditioning or heated windows and seats.

Some car models (usually basic versions of cars), or outdated cars, do not have an on-board computer. The article will discuss how to independently install this high-tech multifunctional device on a vehicle.

On-board computers differ in purpose, which directly affects the characteristics of these devices. When choosing a BC, it is necessary to take into account the purposes of use, and only after choosing the “area” of application of the device, you can proceed to studying the characteristics of the models.

For taxi parks and taxi services, on this website you can download a program for printing and recording taxi waybills, as well as all the necessary road traffic safety magazines.

Characteristics

Important! Depending on the type of on-board computer, certain characteristics of the device play an important role. For example, screen resolution and diagonal are important for multimedia files, or for viewing maps when planning a route. Well, the presence of a huge number of options for controlling the car’s electronic systems is suitable for narrowly targeted on-board computers.

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.

Trip computer

Trip computer (MC), shown in Fig. 37, is installed in a variant version instead of a clock in VAZ 2110, VAZ 2111, VAZ 2112 cars. The MK has 15 functions, divided into 3 groups (see Table 2). The group is selected using buttons 1, 2 and 3.

In each group, functions are divided into basic and additional. The main functions are navigated through the ring using buttons 1, 2 and 3. Additional functions are navigated through button 5. When the ignition is turned off, the computer is always in the “Current Time” mode. When the battery is removed, the clock progress and all accumulated parameters are retained for at least 1 month.

Nuances of choosing an on-board computer

When choosing a bookmaker, a number of factors are taken into account:

Brand of control unit.

Depending on the CU model, you need to select the appropriate on-board computer (BC, combines work with the CU).

Type of power unit.

Depending on which engine is installed in the car, the choice of BC depends. Thus, carburetor engines practically do not have suitable BCs; for a diesel engine, you can already find some BCs, and for injection versions of engines, the most extensive selection of on-board computers is provided. It is worth noting that manufacturers of cars with an injection engine prepare a place for installing and connecting the BC, although the device itself is not included in the kit.

Scope of application of the on-board computer.

Even before purchasing, you need to decide for what purposes the device will be used. If the device shows the temperature “overboard”, fuel consumption and economy indicators, and mileage, then you can purchase a cheap model. If, however, you need a serious diagnostic electronic unit, then you will have to spend money on purchasing a more expensive model.

BC operating temperature.

When purchasing, it is important to remember that the on-board computer will be forced to function in both cold and hot weather. Therefore, it is important to choose a device that is resistant to prolonged exposure to extremely high and low temperatures.

K Line connection problems

K - Line adapter ( VAG COM ) does not connect

When making a K-Line adapter yourself or purchasing it in a store, users in some cases encounter problems connecting the adapter.

This problem has two subtypes:

— Problem when connecting the adapter to a PC (with our K-Line 409 adapter, the kit includes a video instruction on how to use the device, we recommend that you read it if you have any questions)

— Problem connecting the K Line 409 (VAG COM) adapter to the car

To solve the first problem, you need to install the driver for the device located on the disk, then go to the device manager and see if your adapter is displayed correctly. If in the device manager you see your adapter in the COM ports and LPT section without any question marks, etc. then you can rest assured that the drivers are installed correctly. To be more confident, you can double-click on it to find an inscription stating that the device is working normally.

Troubleshooting BC

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.

ODB connector pinout: convenient pin layout

In order to personally diagnose a VAZ-2110 car through the connector located under the steering column, you need to know where to connect this or that equipment. This task is greatly facilitated by pinout, which is a diagram of the placement of contacts. It identifies the following main outputs:

A – ground from the car battery is connected to this output;
B – output is intended for connecting L-Line type equipment. It is not used on all modifications of the VAZ-2110, so be sure to pay attention to this when choosing a computer scanner or adapter;
M – K-Line type devices are connected to this output. They are rightfully considered the optimal choice for self-diagnosis of the VAZ-2110, as they provide excellent interaction with any computer equipment;
H – output to which power is supplied during diagnostic operations;
G is a very important pinout element, since it is it that ensures safety control of all procedures performed and eliminates any short circuits or other emergency situations.

This designation of contacts will allow you to avoid mistakes when connecting diagnostic equipment, as well as perform all the necessary work efficiently. Now that you know the location of the ODB connector, as well as its main components, you can begin to assess the technical condition of the car.

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).

Possible causes of malfunction of the on-board computer and the main ways to eliminate them

One of the most common reasons is a lack of communication with the controller or line-K. What does the current error indicate and what needs to be done:

the appearance of this error directly indicates a broken contact, or a poor connection of line-K with the additional block;
The first thing you need to do is check line K according to the diagram;
in most cases, the cause of this malfunction is a contact break between line-K and the diagnostic block.

Failure in temperature sensor readings

Occasionally, due to exposure to extremely low temperatures, off-board temperature sensors may fail. Typically, in this case, there are two options:

breakage of the corresponding contacts;
failure of the sensor itself or partial loss of functionality.

Note. Sometimes, if there is a practical need, you can install two on-board computers in a car at once, each of which will confidently occupy its own niche.

The instructions for installing the on-board computer with your own hands are quite clear and allow you to easily do everything yourself. However, if the choice is made to do everything yourself, then the use of photo and video materials is a prerequisite. Since a car’s on-board computer costs a very substantial amount of money, the cost of installation at a car service center is quite significant. Therefore, it will be better if you do the replacement yourself, especially since it does not present any practical difficulties.

Diagnostics of DS on VAZ 2110

Location of the regulator in the engine compartment

How to check the speed sensor on a VAZ 2110 on your own? First of all, for this you need to know where the DS should be located, after which its drive is diagnosed. In accordance with the connection diagram, on the tenth VAZ models the regulator is located in the engine compartment, not far from the exhaust manifold. As practice shows, connection wires can rub against a heated collector, causing them to melt.

As a result, a short circuit occurs. As a rule, this problem can be solved by insulating the wires and fixing them so that they do not come into contact with the collector. Another diagnostic option would be to check for a broken cable. This reason is one of the most likely. If the cable is in order and no damage was detected during the process, then the problem lies in the controller itself or its drive.

How to reflash the on-board computer?

A flashing program (for example, BootLoader.exe) is installed on the PC or laptop.
Next, you should connect the bookmaker to your personal computer.
The next step is to connect the power.
In the flashing utility, you need to set the value of the port to which the COM1 data cable is connected.
If the previous step is completed correctly, the “upload file” button will appear, and after its activation, a window will open in which you need to select a firmware file in the “hex” format.
Next, all that remains is to press the “Start ISP” button, and use the on/off key to restart the on-board computer. A loading indicator will be available on the PC display.
After the download of the updated software is completed, the message “download complete” will be displayed on the screen, and the system will also prompt you to start the controller. After confirming the operation, it is necessary to check the functioning of the new BC firmware.

On-board computers are divided into two types

1. Universal - they are suitable for any model. They are most often installed on the roof next to the rearview mirror or on the windshield.

2. Made specifically for certain car models.

In truth, a BC cannot be called an essential item - many owners get by just fine without it.

On the other hand, just imagine what opportunities it gives you.

For example, you need parking sensors, you want to install a DVD, a navigator or something else. For all this you need a separate place. And all of this needs to be managed separately.

If you have an on-board computer on a VAZ 2112, then you will control all devices through it, and they will be connected to it. That is, you save your time and space in the car. Then you may have a question...
