Here are the schemes of control of VAZ-21120 and 21124 engines. They were installed on the Lada hatchbacks of the family of the 2112. The on-board network scheme is also provided. We are talking about engines containing 16 valves, and the electric hammers on the VAZ-2112 consists of separate parts: engine control, general scheme. The chain of power headlights, dimensions, etc. Considered in the first chapter.

The letters are indicated by the terminals to which: A - the dynamic front right, b - radio tape recorder, in - the nozzles harness, g - the diagnostic connector of the EUR, D - the dynamics of the front on the left, E is the diagnostic connector of the heater controller, and the rear speaker Rear speaker on the left, and - BC connector, k - the filament of the glass heater, L is the fifth door actuator, M is an additional stop signal.
All door terminals with closed doors remain open. We bring the electricity to the VAZ-2112 with the description, and the confusion information will be useful to install signals.
Note that the starter power can be connected in different ways. Either the current on the terminal 50 comes directly from the lock, or through the relay 10. The second option (as in the diagram) is less common.
Three relays shown in the diagram are always installed on the block fixed on the block 35 from above (see photo).
The main block of fuses and relays
Here, the part 5 is "relay 9", and 7 - "relay 10".
Powerforces
When the ignition is turned on, the relay 11 closes the contacts. This resolves the work of glass windows controlled by selectors 3, 4, 9 and 10.
Without ignition, windows do not work
Other explanations does not require a scheme.
central locking
The diagram shows the four actuators, as well as the control unit 3. The actuator 7 is in the driver's door.
Actuators, TZ and one terminal block
It would seem that everything is simple. But in the description of the WAZ-2112 power supply, they usually do not report the main thing: the white cord is the entrance for the "Open" command, brown - "close".
There is an option of a scheme where only a confusion (without an actuator) is placed in the module 7.
Lights
The K4 relay includes Middle Lamps, K5 - Far.
Block headlights with single-litam lamps
Stewed selector 3 includes only relaysK5. But in explanation for the electric hammer on the VAZ-2112 it is said that:
- The selector 3 serves to select the "Middle / Far" mode;
- With its help briefly turn on the lamps of darts.
Everything is simple: When the switch 4 is in position II, the K4 relay closes its contacts. And it means, in the "Far Light" mode, all lamps work immediately.
Dimensions, stop signal, backlight
The overall lights 1 and 6 are included with the switch 3. Current from it through the main unit 2, or rather, through the proper function of the lamps. In the diagram instead of the relayK1 shows jumpers.
Dimensions, backlight number, stop signal, devices backlight
Lighting the license plate is the lamps 8. They are included, regardless of the relay operation. The operation of the rear lamp also does not depend on the relay K1, as well as from the switch 3. It is adjusted only by the terminal 10. It is similar to both (limit 11).
The brightness of the backlight of the instruments is regulated by the 9 resistor. But there is a nuance: the switch 3 must be in position I or II. These provisions correspond to the inclusion of the indicator 5 (on the tidy).
Turning
Turn signal lamps 1, 5 and 6 are activated by switch 7. In the power supply circuit of these lamps, the RELAILING RELATER K3, alternately closing the contacts 49A-49 and 49A-31.
The basis of the scheme - the relay-breaker
Without supplying current from ignition lock, turn signals do not work. There is also an emergency signaling mode when:
- Switch 4 is in the upper position;
- The current comes not from the ignition lock, and from the terminal 3 of the sh4 connector.
Round trip).
If the contact is violated in the cartridge of one of the lamps, the switching frequency of the relay K3 is doubled. In the normal state, it is equal to 1.2-1.9 Hz.

In each modern car there is a on-board network - a system connecting all consumers of energy and electrical equipment. These wiring devices are noted on, in particular, in this article we will discuss the legendary domestic "six". Which elements include the VAZ 2106 electrical stroke, which malfunctions are characteristic of it - find out from this material.
[Hide]
Signs of malfunction
What elements includes a scheme of electrical equipment and wiring with a description of 21063? This system includes all the energy consumers, as well as the main systems of the car, including ignition, engine cooling and heating. In the event that the machine does not start, while there are malfunctions in the work of electrical equipment, first of all, it should be checked with the health of the electrical wiring and replace the components failed.
If the engine is not possible, you should first diagnose the state of the battery, as well as the fuel supply to the carburetor or injector.
In the event that the fuel comes normally, then for the diagnosis you will need an electrical circuit of the machine, you need to check the following:
- In the case of carburetor engines, the ignition distributor, coils, candles, and, of course, the wiring itself connects these components. In some cases, the impossibility of starting the engine is associated with damage to which the candles are connected.
- In the event that we are talking about an injection force unit, then the reason may be in the inoperability of the ECM unit. This node is designed to process signals served from sensors, as well as transmit commands to actuators. In general, the control unit is intended to determine the most optimal parameters of the motor operation, but not all cars are equipped with them.
It also happens that the malfunction in the operation of the power unit is associated with the performance of the ignition lock, in particular, we are talking about damaged contact groups.

Carburetor Engine
How the carburetor motor electrical wiring circuit works when the power unit is started:
- The driver turns the key in the ignition lock, while the system begins to feed the power to this node.
- All indicators and badges are activated on the dashboard, in this case the equipment feeds from the battery.
- A low voltage comes to the coil, which is used to form a high-voltage discharge. When the voltage passes through the module, it is converted to high-voltage and enters the distribution unit.
- By means of high-voltage discharge, the drive of the distribution mechanism rotates the crankshaft of the "six" motor. The traver itself, in turn, makes a closure of contacts and transfers the discharge through the high-voltage wires to the candles. Subsequently, this discharge is used to heat the combustible mixture in the motor cylinders (the author of the video is the Channel of the RF auto electrical).
Classic ignition
In accordance with the electrician circuit, the classic ignition includes such components:
- the castle itself;
- coil;
- rubber or distribution unit;
- high-voltage cables with candles.
Using a traver, an interruption of the primary winding of the module is interrupted, after which the high-voltage voltage is supplied in a certain sequence on the cylinders. As mentioned above, the coil is used to convert a low-voltage voltage to high-voltage.
In the event that when you try to start the engine, nothing happens, then the reasons may be such:
- Damage to the wiring on the plot between the module and the generator node. With such a problem, you should diagnose the status of contacts, as well as the integrity of the electrical caps.
- The failure of the coil itself. In this case, the operation of the device can be checked using a spark - a cable is retrieved from the distributor and comes into contact with the body or engine of the machine. If, when trying to start a motor, nothing happens, this suggests that the device is subject to replacement.
- Damage to the wiring on the plot between the candles and the distributor. In this case, it is necessary to diagnose the state of the distributor cover, in particular, check the slider located inside, as well as the wires (author of the video - the channel Alexander AMOCHN Kolomna AAC).
Electronic ignition
VAZ 2106 cars were also completed with electronic or non-contact ignition (BSZ). A fundamental feature of such cars is that an electronic switch was additionally mounted between the distribution mechanism and the coil itself. In addition to the main components, BSZ includes a switching device, as well as a sensor distributor.
Using the latter, the control pulses are transferred to the switch device to create a spark, after which the signals are distributed over the cylinders. The main purpose of the switching device consists in converting control signals into a pulse voltage that is fed to the coil winding, in particular, we are talking about the primary winding. The presence of a switch contributes to improving the formation of a discharge, especially if the power unit operates on a depleted combustible mixture.
Injector Engine
As for injection force aggregates, such motors differ from the carburetor versions as follows:
- in the first there is an electric pump used to increase the pressure in the fuel system;
- in this case, the combustible mixture is formed directly in the cylinder, while in the carburetor versions, its formation occurs directly in the carburetor;
- in the injectors, fuel injectors are used, which provide a normal fuel injection;
- the presence, which makes it possible to accurately determine the moment at which the injection of a combustible mixture is needed (the author of the video is the channel tips to the motorist).
As you understand, injection force aggregates are equipped with a large number of different sensors and controllers. Therefore, if the motor does not start, then the reason may be in trouble in the operation of the electrocups or the sensors themselves.
If we are talking about the sensor, then such a breakdown can be determined by your own hands:
- first, it is necessary to disconnect the wiring from the controller; the connector is retrieved;
- next, using the multimeter, the resistance is diagnosed;
- if the values \u200b\u200bobtained differ from normalized, then the device is most likely to be replaced.
Instructions for diagnosing and replacing wiring
Before proceeding with the replacement of wiring and failed components, it is necessary to diagnose the system.
How to check the tension:
- For testing, you will need a lamp with wires, one of its dipsticks should be connected to the minus terminal of the battery or the "Six" bodies.
- Another contact from the lamp connects to the diagnosed electrocups. It is necessary that the probe is as close as possible to the battery or a safety device.
- In the event that the control as a result of the connection began to burn, this suggests that the voltage on the diagnostic area is available. Testing continues in a similar way until the damaged chain is detected. As practice shows, often faults in the operation of the electrical system are associated with a bad connection, therefore it is primarily recommended to check the contacts (the author of the video - the VAZ channel 2101-2107 repair and maintenance).
You can also check the integrity of the wiring, this is done in order to determine the discontinuity in electrocups.
To do this, do the following:
- To begin with, turn off all the voltage from the electrical circuit and make it diagnostics for integrity. To do this, you can use a control lamp with a connected power source.
- Both contacts from the lamp should be connected to the ends of the electrical circuit. If there is no such possibility, then one checklist is connected to the positive contact, and the other is connected to the ground, that is, the body of the car. In the event that after connecting the lamp caught fire, then this suggests that the wiring portion is intended. If the lamp is not caught fire, this suggests that there is damage in the electrical wiring.
- Similarly, the lock is diagnosed, for this, contacts from the check required will be connected to its terminals. When activating the lock, the light source must turn around.
Electrical equipment on the VAZ 2106 car was performed on a single-wire diagram - negative conclusions of sources and consumers of electricity are connected to the "mass" that performs the function of the second wire. In the 90s, small changes were made to the electrical equipment scheme. So, now one beep is installed on the car without switching it on, the lighting lights of the open front doors and the lamp relay of the hand brake are not used. Also on the car install the rear fog lantern. The heating system of the rear window can be installed onto a part of the car. Most chains are included in the ignition switch. Always included (regardless of the position of the key in the ignition switch) of the power circuit of the audio signals, cigarette lighter, stop signal, plafoons, a portable lamp power outlet, an alarm power chain, and an open-door signaling lights.
