In this article I will present a diagram of the ignition system for a VAZ 2110 car, as well as the principle of its operation.
The content of the article:
The ignition system is one of the most important engine management systems in a car. This technology is intended to ignite a mixture of gasoline and air in the engine. This is ensured by the appearance of a spark. The ignition is part of electrical systems of the machine.
Car ignition system wiring diagram
The VAZ 2110 contactless ignition system consists of the following basic elements:
- car battery;
- generator;
- plug connector;
- ignition switch;
- distributor sensor;
- switch;
How the ignition system works and how it works
On the VAZ 2110, they abandoned such familiar ignition elements as the coil and distributor. So, a special ignition module is used here, which consists of high-energy control electronics, as well as a pair of coils. It is important to note that such a system does not require frequent servicesince there are no moving parts. The VAZ 2110 ignition system also does not require special adjustments, because for this a controller is installed here. He carries out all the settings and adjustments.
The ignition system is based on the “blank spark” method. This is a special method for distributing the spark. As you know, the cylinders in a car engine work in pairs (the 1st cylinder with the 4th, and the 2nd with the 3rd). So, the spark is triggered in two cylinders at once: the working spark is in the cylinder where the compression stroke of the mixture occurs, and the idle spark is in the one where the exhaust stroke is carried out. Because the current in the windings of the coils of the system is constant, it turns out that on the first candle the electrons move from the central electrode to the side electrode, and on the second - vice versa (from the side to the central one).
Depending on the type of engine, two types of spark plugs can be used on the VAZ 2110. So, for 8-valve engines, candles of the A17DVRM type are used, and for 16-valve engines - AU17DVRM (here the turnkey size is reduced to 16 mm). In this case, the distance between the electrodes of the candles is only about 1.0–1.15 mm.
As we already noted above, an element such as a controller is responsible for controlling the ignition. To control the system most accurately, the controller analyzes the following information:
- coolant temperature;
- current position and speed of the crankshaft;
- the presence of detonation;
At first glance, the system is quite complex. But the operation is very simple. In addition, maintenance and repair of the ignition system of the VAZ 2110 and other models does not take much time.

Here are the control diagrams for the VAZ-21120 and 21124 engines. They were installed on the Lada hatchbacks of the 2112 family. on-board network... We are talking about engines containing 16 valves, and the wiring diagram for the VAZ-2112 consists of separate parts: engine control, general scheme... Headlight supply circuit, dimensions, etc. covered in the first chapter.

All door switches remain open when the doors are closed. We provide a wiring diagram for the VAZ-2112 with a description, and information about the limit switches will be useful to signal installers.
Note that starter power can be connected differently. Either the current to terminal 50 is supplied directly from the lock, or through relay 10. The second option (as in the diagram) is less common.
The three relays shown in the diagram are always installed on a block fixed to block 35 from above (see photo).
Main fuse and relay box
Here part 5 is "relay 9" and part 7 is "relay 10".
Window lifters
When the ignition is on, relay 11 closes the contacts. This allows the operation of the power windows controlled by selectors 3, 4, 9 and 10.
Windows do not work without ignition
The diagram does not require any other explanation.
central locking
The diagram shows four actuators, as well as a control unit 3. Actuator 7 is located in the driver's door.
Actuators, central locking unit and one limit switch
It would seem that everything is simple here. But in the description on the VAZ-2112 wiring diagram, the main thing is usually not reported: the white cord is the input for the “Open” command, the brown one is “Close”.
There is a variant of the circuit where only the limit switch is located in module 7 (without an actuator).
Headlights
Relay K4 switches on the low beam lamps, K5 switches on the high beam.
Headlights with single filament lamps
Steering column selector 3 only activates the relayK5. But in the explanation to the wiring diagram on the VAZ-2112 it says that:
- Selector 3 is used to select the "near / far" mode;
- With its help, the high beam lamps are briefly turned on.
It's simple: when switch 4 is in position II, relay K4 closes its contacts. This means that in the " high beam»All lamps work at once.
Dimensions, brake light, backlight
Side lights 1 and 6 are turned on by switch 3. From there, the current flows through the main unit 2, or rather, through the lamp health relay. In the diagram instead of a relayK1 shows jumpers.
Dimensions, room lighting, brake light, instrument lighting
Number plate lighting is lamps 8. They come on regardless of relay actuation. The operation of the reversing lamps also does not depend on the K1 relay, as well as on the switch 3. It is controlled only by the limit switch 10. In a similar way, and (limit switch 11) are switched on.
The brightness of the instrument illumination is regulated by a resistor 9. But there is a nuance: switch 3 must be in position I or II. These positions correspond to the inclusion of indicator 5 (on the tidy).
Turn signals
Turn signal lamps 1, 5 and 6 are activated by switch 7. A relay-breaker K3 is included in the power circuit of these lamps, alternately closing contacts 49a-49 and 49a-31.
The basis of the circuit is a relay-breaker
Without power supply from the ignition switch, the turn signals do not work. There is also an operating mode " Alarm"When:
- Switch 4 is in the up position;
- The current does not come from the ignition switch, but from terminal 3 of the Ш4 connector.
Round trip).
If the contact in the socket of one of the lamps is broken, the response frequency of relay K3 is doubled. In the normal state, it is equal to 1.2-1.9 Hz.

The principle of operation of the electrical equipment of the VAZ 2110 car is borrowed from other models of the VAZ family. This means that all devices are connected in a single-wire circuit - the car body performs the function of the second (negative) wire. And the negative terminals of consumers and sources of electricity are connected directly to the body.
For ease of maintenance and installation, the electrical wires on the diagrams are made different colors, identical to those laid in the car, so that you can visually determine their purpose.
For brevity, colors are indicated by the first letters of the name:
- Blue - "G";
- Brown - "K";
- Gray - "C";
- White - "B";
- Orange - "O";
- Yellow - "F";
- Black - "H";
- Green - "Z";
- Pink - "P".
For reference: the red wire is traditionally used to supply power from the positive terminal of the generator or battery... Therefore, in all the diagrams that the factory instructions contain, it is indicated by the letter "P".
Fuses
Most of the electrical circuits and all the wiring of the VAZ 2110 to the injector are protected from short circuits by fuses.
However, without protection, the VAZ 2110 is:
- The wire from the battery charge relay to the battery itself,
- VAZ 2110 wiring to the injector, which is responsible for the ignition and engine start circuits;
- Alternator wiring (excluding the field winding, which is activated after turning the key in the ignition switch and starting the engine).
Fuel injection system
If you intend to service the fuel injection system with your own hands, then you must know the principle of its structure and operation.
According to the generally accepted algorithm:
- The amount of fuel required to form a portion of the mixture is regulated by a controller that sends a pulse signal to the injectors;
- The controller itself, before giving a signal, monitors the signals coming from the sensors about iCE operation and its systems;
- Based on these, it calculates the pulse width.
For reference: to understand the principle of operation of an injection motor, it would be nice to watch video materials. From them you will learn that the impulse lasts hundredths of a second, but even a change in such a small value affects the amount of fuel supplied to the cylinders.
In its work, the controller is guided by data from:
- Engine speed sensor (in the diagram - 1);
- Air flow sensor (2);
- Crankshaft position sensor (input 2).
And on their basis, it implements the inherent work algorithm:
- Gives an impulse to turn on fuel injectors (4);
- Gives an impulse to candles (5).

conclusions
Understanding the principles of work injection engine, as well as a short circuit protection circuit for wiring, you can easily detect problem areas and take measures to quickly eliminate them.
Now more and more motorists are striving to replace the carburetor on their VAZ-2110 with an injector, which has a number of significant advantages. It allows the valves in the engine to work much more efficiently, reduces the load on the engine and the average fuel consumption in the vehicle. At the same time, it is simply impossible to install an injector without a circuit, even if you are a professional car service worker.
What is the VAZ-2110 wiring diagram for?
When replacing or repairing an injector with 8 valves, the electrical circuit serves as a kind of guide, with which you can deal with all the nuances in the process of connecting specific wiring parts. In addition, the VAZ-2110 wiring diagram when using an injector with 8 valves allows you to understand the functioning of all wiring devices.
In the diagram, the injector valves are evenly spaced, while the system itself is represented in the form of 2 combined components:
- Fuel distributor;
- Electrical equipment for the ignition control system.
Also on the diagram with 8 and 16 valves, the location of the electronic unit is indicated, with the help of which the work of the above 2 systems is coordinated. Redundant equipment, in turn, protects the wiring from overloads and increases the efficiency of the entire injection system.
Advice: if you are going to repair the injector, be sure to look at the wiring diagram for the VAZ-2106. This will give you the opportunity to replace all defective parts without damaging general work car wiring.

The diagram of electrical wires and fuses gives an understanding of the entire operation of the injection system, and also shows the specific position of each of the elements. The following elements are located on it:
- Central nozzle. Serves as a distributor of fuel supply to the system. There is also a special type fuel regulator, which works as a sensor and monitors that the fuel supply indicators do not go beyond the normalized limits.
- Membrane regulator. Monitors fuel pressure in the ignition system and removes excess fuel back into the tank body.
Advice: make sure that the pressure in the fuel supply system does not exceed 300 MPa. Otherwise, you will see the corresponding icon on the instrument panel and you will most likely have to replace the coolant with the VAZ-2110.
- Design check valve... It regulates the position of the cross diaphragm, which is subjected to constant pressure from three sides: on the one hand, the pressure of the fuel being poured, on the other hand, the tangential load from the suction volumes of air, and on the third side, the tension from the spring fixed to the valve.
How to regulate the fuel supply process using the electrical circuit?
According to the scheme described above, the fuel regulation in the car is performed. Moreover, it depends not only on the load of the valves in the engine, but also on the corresponding position relative to the throttle valve. Using the scheme electrical wiring and valves, it is possible to understand which of the relay or fuses is working with a malfunction, and replace it in time. In this case, one of the main roles in the supply of fuel is performed by electrical equipment (controllers) that regulates the operation of the injector.
How does the controller monitor the injector operation?
When determining the specific position and opening time of the nozzle structure, the specific volume of fuel entering the VAZ-2110 cylinder valves is determined. At the same time, thanks to special sensors installed on the motor, the on-board computer records specific values \u200b\u200band transmits them to the controller.
Subsequently, the controller, based on the information emanating from the on-board computer, makes a decision on the position and duration of the injector flap opening. In the event of a controller malfunction, the injectors will not be adjusted correctly, and the engine may stall on the move.
Advice: when the engine is started, the injector controller operates in asynchronous mode until the engine reaches a certain number of revolutions. That is why, after replacing the silent blocks of the front levers with a VAZ-2110, you should warm up the car for 10-15 minutes.
How does the malfunction of the electronic control unit affect the operation of the injector?
Block electronic control the VAZ-2110 machine consists of 3 high-precision components:
- ROM - data storage devices (memory);
- EPROM - a device for transmitting dynamic data;
- RAM - block regulating memory.
Advice: the whole complex of the presented elements will function only if there is voltage in the circuit. If there is no voltage in the wiring, then it is necessary to troubleshoot the fuse box on the VAZ-2110.
In this way, the electronic unit control acts as a kind of microprocessor, which is responsible for the operation of the entire fuel supply system. If it breaks down, even an experienced motorist cannot repair it with his own hands. For repairs, contact the nearest car service and wait for the result. If the unit does not have any faults, the breakdown must be looked for among the injector and controller elements.
Advice: in the center of the dashboard on a VAZ-2110 car, a signal light called "CHECK ENGINE" may light up. In this case, the problem is definitely not in the control unit, the problem is related to a malfunction of the controller.
So, if you notice that your engine has begun to stall constantly while driving and spends more fuel at the same distance as before, refer to the injector diagram for the VAZ-2110. With a little understanding of each of the elements, you can quickly find defective item and replace it.
