Operating instructions for the on-board computer VAZ-2115

Cars manufactured on the territory of the Russian Federation are equipped with a computer. The first on-board computer appeared on the VAZ-2114. In simple terms, the on-board computer can be considered a kind of electronic reference book on the condition of the car. The driver needs it in order to understand the condition of his car, as well as what faults have appeared in it.

The first on-board computers on domestic cars performed the following functions:

1. Controlling the amount of fuel poured into the tank.
2. An approximate calculation of the distance that can be driven with the remaining fuel in the tank.
3. Monitoring the temperature of the coolant in the engine, as well as preventing it from overheating.

The modern on-board computer on the VAZ-2115 is designed for:

• transmitting information about indicators “online”;
• displaying information on the information panel;
• reflections of route parameters, such as current fuel consumption, travel time, number of kilometers traveled, etc.;
• diagnostics of the engine condition with subsequent display of errors on the on-board computer screen.

Among other things, depending on the vehicle’s configuration, its on-board computer may receive the following data:

• information about the time of the next vehicle maintenance;
• information about the need for adjustments to certain vehicle functions;
• warning about the need to renew the insurance policy;
• information from the organizer;
• parameters at which the cooling system fan will automatically turn on.

Removing the on-board computer

It happens that car owners do not like the way the standard on-board computer of the VAZ 2114 installed during assembly works. Or there is a desire to change it to a more advanced model. This device can be removed by yourself.

Before starting all dismantling work, it is imperative to find out from the car dealership where the car was purchased whether this work will affect the warranty period. Most car dealerships will cancel your warranty.

Dismantling process:

1. Before starting work, you need to turn off the power to the car; to do this, you need to disconnect the negative terminal from the battery.
2. Remove the radio control panel.
3. Remove the radio by unfastening the connected wires.
4. Put your hand through the opened opening and unclip the fastenings of the computer unit.
5. Now you can carefully remove the computer by disconnecting all connected wires.
6. Remove all additional devices connected to the computer.
7. Reconnect the car radio with wires and install it in place.

Device installation

You can install the on-board computer on the VAZ 2114 yourself. You will need a meter piece of wire and several screwdrivers. The main actions required from the user are as follows:

1. Remove the cover from the instrument panel. The computer will be located here.
2. Find a 9-pin block, connect the main wire to the second contact.
3. The second end of the wire is pulled under the instrument panel to the diagnostic block.
4. If the block is Euro 2 type, connect the wire to connector M, if Euro 3 - to socket 7.
5. Additional elements of the device are connected, if any (sensors, etc.). How to connect an on-board computer to a VAZ with sensors is described in detail in the instructions for the device.
6. Next, the computer is mounted in the instrument panel, after which its initial setup is carried out.
7. The connection of the on-board computer is completed. Installation is carried out similarly for model 2109.

What is a plasma device in a car, and why should it be turned on?

The car has not only obvious functions, but also hidden ones, the presence of which many drivers are not even aware of. One of these options is “Plasmer”. Let's figure out what it is and why this option is needed?

Option - assistant

This option is designed to make it easier to start the engine in the cold season. It is used when the car has been left in the cold for a long time without moving. Since the winter start of the engine is accompanied by a large load on all its units, there is a need to somehow reduce this load and make the engine easier to operate. Activating the “Plasmer” option enables pairwise operation of the spark plugs in idle mode. That is, current is supplied to the spark plugs and a spark occurs, but there is no fuel-air mixture in the combustion chamber, which means the engine does not start.

All about the on-board system

Below is a list of sensors available in the VAZ 2110 car system?

• Alarm for low oil level in the crankcase.
• Fluid level alarm in the windshield wiper system (see).
• Insufficient coolant alarm.
• Open door alarm.
• Alarm during malfunction of brake lights and side lights.
• Alarm for front brake lining wear.
• Seat belt warning.

Each of these alarms has several operating modes:

• Off state.
• Standby mode.
• Control before departure.
• Basic mode of parameter control.

Off state

The off state of the on-board control system occurs when the ignition key is not in the keyhole.

Control before departure

If the door is open in this position, the door open alarm will be activated. In this case, you must either close the door or turn the ignition key and start the car engine. It is at this moment that the transition to pre-departure control occurs.

Basic mode

At the last level of basic parameter control, the alarm can turn on:

Alarm of a parameter that has deviated from the nominal value. Along with the light signal, a sound signal can be given, which will notify the driver of a malfunction within 3 seconds. If another breakdown occurs at the same moment, the system begins to operate in priority mode, which is given to a more important problem

At this moment, a less important breakdown is constantly illuminated.

Additional functions

"Tropic" function. Automatic fan control

Allows you to change the cooling fan activation threshold. I set the response temperature to +98°C.

Function "Plasmer". Drying and warming up candles

In difficult weather conditions (humid weather, freezing temperatures), pre-drying and warming up the spark plugs several times increases the likelihood of a successful launch.

Resetting the controller to its original factory settings. In this case, the dynamics and fuel consumption will be restored to normal values.

Indicator of not switched off lights or dimensions

When you turn off the ignition, there is a sound notification that the headlights or headlights are not turned off.

Speed ​​Warning

It is possible to set up an audible warning about speeding. I don’t use this function because I always try to adhere to the speed limit.

Malfunctions of the electronic engine control unit and diagnostics

Although manufacturers make the ECU in the form of a protected box, placing the hardware inside a durable metal case, this device can also fail. Problems with the control unit may be accompanied by unstable operation of the internal combustion engine or the inability to start the engine, deviations in the mixture formation processes, disturbances in the operation of the transmission (usually automatic), etc.

To check the ECU, you should start with a visual inspection, which allows you to identify obvious defects (for example, cracks in the housing). However, if none are found, this still does not allow us to exclude possible damage to the microprocessor, since there are many reasons for the failure of this device.

Among the simplest, experts highlight:

• overheat;
• severe corrosion and moisture ingress;
• damage due to impact loads;
• short circuit;

Also, the culprit of the problems may not be the ECU itself, but poor contact with sensors, oxidation at the point where the wires are connected. Let us note that often problems with the control unit are caused by the banal irresponsibility of the car owner himself.

For example, when washing the engine under pressure, the block is not properly protected from moisture; the machine is operated in wet weather with elements removed (without fenders, hood). Owners often ignore the fact that the ECU is not securely mounted at the installation site or there are problems with the wiring, which can lead to a short circuit, etc.

The electronic unit can also be damaged by lighting it from another car with the engine running, unqualified installation of additional equipment in the car, or problems in the high-voltage part of the ignition system.

Let us add that there are also cases of complete failure of the ECU after attempts at unprofessional or independent repair of this type of device, as well as chip tuning

It is important to understand that on some models the unit is beyond repair, that is, a complete replacement of the unit is expected

In this case, after carrying out a superficial diagnosis, the owner removes the ECU and tries to disassemble/repair it. Then it often turns out that some sensor is still causing the problems, but after repair attempts the unit is no longer suitable for further use.

For this reason, it is important to understand that a comprehensive professional computer diagnostics must first be carried out. Only after this can you decide what to do, change or repair the engine control unit

If we talk about an accessible check that a car enthusiast can perform on his own, this is a banal replacement of an existing unit with exactly the same one that is known to work. For example, you can borrow an ECU from the same car at a disassembly facility as collateral, install such a unit and check the operation of the internal combustion engine. If the machine works fine with the new unit, then the problem is obvious.

We also note that it is not always possible to eliminate a breakdown simply by replacing the controller. As mentioned above, often the root cause of ECU failure is not the unit itself. In simple words, if, for example, there is a short circuit in the wiring, the new control unit will quickly fail in the same way as the previous one.

What it is

In the modern world, we cannot imagine ourselves without a personal PC. This device has become firmly entrenched in our lives; without it, many would be without hands. Most smartphones are not inferior in their characteristics to various computers and have even become better than them in some ways.

But in this article we will talk about all kinds of PCs in the car. These are what drivers use in their cars. They manage processes, among the basics:

1. Air temperature.
2. Amount of fuel consumption.
3. How many kilometers have been traveled?
4. Any damage.
5. Network failures and many others.

Currently, the route PC has begun to perform many functions. It has an LCD display. It is controlled using a touchscreen or by pressing buttons. Most PCs can be controlled by a smartphone.

VAZ 2110 instrument panel does not work

VAZ 2110 instrument panel does not work April 17, 2016 at 18:27

The instrument panel of the VAZ 2110 includes a number of elements, including a tachometer, speedometer, oil level sensor, fluid temperature indicator in the system, twelve control lights, six dashboard backlight lights, an additional socket for installing a control light and blocks for connecting wires. Wire blocks consist of two parts, which are responsible for different elements of electrical circuits

If the instrument panel does not work on a VAZ 2110, it is important to know what type of part is installed on the car. This model was equipped with two types of dashboards: the old type with symmetrically located instruments and a new type, on which indicators for the amount of fuel and coolant level are located on the right side of the panel

Why doesn't the dashboard work on the VAZ 2110?

Many drivers are faced with a problem when the instrument panel on a VAZ 2110 completely stops working. In this case, the devices themselves do not function and the instrument lamps do not light up. This failure indicates that the 15-amp fuse has failed. This part is marked F6 and is located in the mounting block located to the left of the steering wheel. If the instrument panel on a VAZ 2110 does not work due to a blown fuse, replacing the spare part will not be enough. In this case, you will have to find the cause of the burnout, because the new fuse may also burn out after installation.

It is important to find the place where the electrical circuit shorted and eliminate it

In some cases, the arrows on the instrument panel do not show real values, but simply jump from the minimum to the maximum mark. In this case, the breakdown may consist of poor contact with the ground. The ground wire leading from the instrument panel is attached to the partition that separates the interior from the engine compartment. You can find the contact point by removing the tape recorder from the socket. If the car has an alarm system, the wire can be moved behind the interior trim, to the area of ​​the driver’s left foot. A similar malfunction can occur during the installation of the radio: if, when connecting the negative wire to the tape recorder, the negative wire of the dashboard was disconnected. The wire may have been attached poorly. Due to body vibration, the fastening could become loose or completely detached.

If the instrument panel does not work on a VAZ 2110, and no problems are found with the fastening, you will have to conduct a thorough diagnosis of the dashboard itself. To do this, remove the panel as much as possible from the standard socket without disconnecting the wires leading to the pads. We check the white ground wire located on the block, going to the first contact. After this, we check the voltage at contact numbers 9, 10 and 6. During normal operation of the panel, the voltage should be twelve volts. Next, we inspect the tracks located on the back side of the instrument panel

It is important that all the tracks are intact, since it is through them that the electric current is conducted.

Another reason for instrument panel failure is related to the cigarette lighter. The fact is that many drivers connect chargers or power supplies designed for high current to the cigarette lighter socket. This disables the cigarette lighter and leads to the blowing of fuse F19, which is also responsible for the operation of the instrument panel. If you urgently need to return the instrument panel of the VAZ 2110 to working condition, and the fuse turns out to be intact, you can disconnect the cigarette lighter connector. If the instrument panel does not work on a VAZ 2110, most often you can fix the problem yourself without going to a repair shop. The main thing is to correctly determine the cause of the breakdown and select new fuses and failed spare parts.

But if you knew how to do this, you would simply say - put such and such a number on a full/empty tank.

What if, on the contrary, fill the tank full and adjust it to the factory capacity?

There's something with Dot voltage that needs to be set. As I realized on an empty tank, inform the bookmaker that the air is blowing at a minimum. And on a full tank that's the maximum.

This way the bookmaker will remember the extreme positions.

Okay, I figured it out. Thanks to all! There is another question: I don’t have the 4th leg on my BC (it controls the Carlson). If you solder this leg yourself, will it function? According to the program, there is control, but there is no contact.

alexii54

What ecu do you have, Bosch 7.0?

Most likely, if there is no contact, then it is not routed on the board and the BC program, and it will not be possible to make it..

And if it’s a different computer, then you don’t need it. This wiring.

Added after 4 minutes 10 seconds:

I took the BC to check for errors and turn on the fan (tropical). But I missed the contacts (inexperience). Now we'll have to look for another diagram to finalize it.

Trouble-shooting

To eliminate the malfunctions indicated by the alarm, you must take important troubleshooting steps:

• If the low oil alarm is on, add oil to the engine crankcase.
• Washer system alarm - add windshield washer fluid.
• Alarm – bringing the coolant level to normal.
• Door open alarm - close the doors or remove the key from the ignition.
• Malfunction of brake lights and side lights - correct the operation of these systems.
• The disadvantage of brake linings is to fix the damage.
• Seat belt warning – fasten the seat belts in the required position.

All these alarm indicators are placed in a special place and are called the on-board system display unit for the VAZ 2110. When triggered, they emit both a light signal and a sound signal. There are two sensors that constantly operate when the engine is on. This is also a brake pad wear sensor. If they are faulty, the on-board control system, or rather the on-board systems display unit of the VAZ 2110, will not show a reliable result. It is necessary to constantly monitor the operation of these sensors.

It should be noted that the moment you turn the ignition key, all indicators on the dashboard are fully tested. At this point, it is necessary to check the operation of each alarm light. When the door is not closed, it turns on

You need to carefully monitor these devices, as their working condition is necessary and very important.

The main differences between a BC injector and a carburetor

The main differences between the bk, depending on the type of power supply, are the on-board capabilities for the VAZ 2110. The carburetor type is the simplest. The main reason is that carburetors are largely controlled mechanically, and electronics play a secondary role. Therefore, its standard set of functions is extremely small. You can find out about:

• time of day or set an alarm;
• current and average fuel consumption, as well as power reserve;
• average speed and driving mode;
• engine or outside air temperature;
• diagnostic information that allows you to find out about an engine operation error and decode it.

How to reset errors?

Upon completion of self-diagnosis, errors must be reset. How to perform this action can be found in the corresponding recommendations of the car manufacturer. In practice, it has been established that the reset procedure is identical to the manipulations to launch a new system check. Here the controllers are reset and the reset itself occurs, which is provided by special software tools present in the ECU software. The procedure is also performed during the next service in case of characteristic malfunctions. For example, code “0171” may be displayed with annoying consistency, indicating low-quality fuel in the LADA Kalina car system of the same name. This should alert the owner to changing the refueling location. Owners also consider “1545”, “0422” and “1426” to be common errors.

What computers can be installed on the VAZ-2115

On sale you can find a variety of models of on-board computers for domestic cars. The most important thing is that they work with electronic control units installed on VAZ cars. You should not skimp on trip computers, since expensive devices will be able to provide thorough diagnostics of the car and promptly warn you about malfunctions. They have a much longer service life and more functionality than cheap options.

On sale you can also find on-board computers that are installed instead of the instrument cluster. They are much more convenient, since all information about the operation of the vehicle systems is in front of the driver’s eyes.
