Wiring diagram VAZ 2112 - general wiring diagram for electrical equipment and instruments, engine control unit and fuses. When servicing and repairing the engine management system of this and other cars of the VAZ family, always turn off the ignition. Disconnect the controller from the wiring harness when welding. The controller contains electronic components that can be damaged by static electricity, so do not touch the terminals with your hands. With the engine running, do not disconnect or repair electrical connectors.

A distributed phased injection system is installed on the VAZ-2112 engines and parts of the VAZ-2111 engines: the fuel is supplied by the injectors alternately in accordance with the order of operation of the cylinders, which reduces the toxicity of the exhaust gases. In this case, a phase sensor is installed on the cylinder head, and a disc with a slot in the rim is installed on the camshaft pulley.

Here are the control circuits for the VAZ-21120 and 21124 engines. They were installed on Lada hatchbacks of the 2112 family. The on-board network diagram is also given. We are talking about engines containing 16 valves, and the wiring diagram for the VAZ-2112 consists of separate parts: engine control, general circuit. Headlight supply circuit, dimensions, etc. discussed in the first chapter.
The letters designate the terminals to which it is connected: A - Front right speaker, B - Radio tape recorder, C - Injector harness, D - EUR diagnostic connector, D - Front left speaker, E - Heater controller diagnostic connector, F - Rear right speaker, W - Rear left speaker, I - BK connector, K - Glass heater thread, L - Fifth door actuator, M - Additional brake light.
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).
Here item 5 is "relay 9" and item 7 is "relay 10".
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.
The diagram does not require any other explanation.
The diagram shows four actuators, as well as a control unit 3. Actuator 7 is located in the driver's door.
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).
Relay K4 switches on the low-beam headlights, K5 switches on the high-beam headlights.
It's simple: when switch 4 is in position II, relay K4 closes its contacts. And this means that in the "high beam" mode, all lamps work at once.
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 relay K1 shows jumpers.
The license plate lighting is lamps 8. They come on regardless of the 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 regulated only by the limit switch 10. The brake light lamps (limit switch 11) are switched on in a similar way.
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 signal lamps 1, 5 and 6 are activated by switch 7. A relay-breaker K3 is included in the power circuit of these lamps, which alternately closes contacts 49a-49 and 49a-31.
Turn signals do not work without power supply from the ignition switch. There is also the "Alarm" operating mode when:
If the contact in the socket of one of the lamps is broken, the operating frequency of relay K3 is doubled. In the normal state, it is equal to 1.2-1.9 Hz.
For a car to work as efficiently and reliably as possible, a well-coordinated operation of all its systems is required. One of the leading roles in this matter is the electrical wiring.
Today we will talk about the wiring diagram that is used on VAZ 2110 cars, study the main components, consider the difference between injection and carburetor versions.
Regardless of the type of engine used, the basis for the wiring used in the VAZ 2110 car is the same. The schematic is easy to find, but not easy to figure out.
Let's consider the basic principles of wiring.

The first versions of the VAZ 2110 model, which the domestic plant began to produce, were equipped exclusively with carburetor engines. Only after some time did more modern injection versions appear. They are objectively better. But this does not take away the fact that many have dozens of them under the hood of a carburetor.
Are there any significant differences in terms of wiring between the carburetor and the injector? We can say no. The carburetor systems are used almost completely the same as on the more modern version.
Also, you will not face serious problems in the form of electrical wiring if you suddenly want to replace the carburetor motor with an injection one or equip the car with additional electrical equipment. You will even find identical plugs in the engine compartment.
The only nuance of the transition from the caruretor to the injector is the need to install additional wiring from the fuel pump to the on-board computer.
In addition to the wiring, which is identical for the carburetor and the injector, the latter is additionally equipped with fuses and sensors.
In practice, due to the large number of regulators that ensure the operation of an electronic engine control unit of an injection type for 8 or 16 valves (it is not on the carburetor), the system turns out to be more complex. To repair it, you need to carefully understand all the components and their location.
Vehicle wiring is one of the main components that ensure the normal operation of a car. This material will allow you to understand the main features of the VAZ electric circuit of the tenth model. What the electrical circuit of a VAZ 2110 car looks like, what are the malfunctions characteristic of it - read about this below.
It doesn't matter what engine the Lada is equipped with - it can be a VAZ 2110 injector or a 2110 carburetor - the basis of the electrics in this model will not differ.
Below are the main features that the VAZ 2110 wiring has:
The first models of 8- and 16-valve VAZ 2110 cars were equipped only with carburetor engines. A few years later, the domestic automobile concern began to equip its vehicles with injection engines. Of course, the injection model is more advanced, but today in Russia and the CIS countries tens of thousands of carburetor machines with 8- and 16-valve internal combustion engines are used.
Most likely, a dozen owners are interested in the question - on carburetors and 21102 injectors the circuit is different or not? In principle, there are no special differences between these versions in terms of the electrical circuit. Almost all systems used on injection 8- and 16-valve engines are identical to carburetor units. Accordingly, if you need to replace the carburetor engine with an injection one or install additional devices, then there will be no problems with this. If you look into the engine compartment, you can notice that both versions of the car even have the same outputs and plugs.
Car wiring diagram 2110
One of the main points to consider when replacing a carburetor with an injector is the connection of the fuel pump. In order for the fuel pump to always work correctly, it is necessary to additionally lay the wiring for its power supply to the control unit.
In addition to the fact that the electrical wiring in the carburetor and injection versions is virtually identical, the injector has certain features. For example, it is equipped with fuses, and there are more sensors in the injection versions of the car.
In fact, as a result of the fact that these cars are equipped with a large number of different sensors designed to provide the functionality of the ECU, the system itself is more complex. It should be noted that there is no electronic control unit on carburetor versions. In order to repair the system, if necessary, you need to clearly know about all its components and their installation locations. The very same electrical circuit in any car is divided into engine compartment and salon. Above you can familiarize yourself with the circuit diagram, and below are its main designations.
The request returned an empty result.
In any case, when certain malfunctions are identified in the wiring, diagnostics must begin with a search for contacts. To check their condition, you first need to check the wires themselves, which are included in the wiring harness.
There may be several options for diagnosis:
visual diagnostics, consists in identifying breaks by eye;
use of special resistance devices;
checking the reliability, as well as the integrity of connectors, contacts, etc. (video author - Evgeny Churilov).
First, you need to diagnose the condition of high-voltage cables. It is they who are mostly responsible for ensuring the functioning of any electrical equipment in the vehicle. Moreover, high-voltage cables are always in a hostile environment. Accordingly, it is often the electrical circuit that is the main reason for the failure of equipment or devices.
The following are the main symptoms of high voltage cable faults:
When you turn on the radio on your car stereo, you begin to hear interference that was not there before.
The engine begins to triple; while driving, the car may jerk.
Gasoline consumption rates are increasing.
The motor periodically begins to "choke", especially when driving at low speeds.
The level of exhaust gas toxicity increases significantly.
In the event that you notice that the electrical circuit of your dozen is not working correctly, first of all you need to contact an electrician for help. Or you can independently diagnose high-voltage wires, for this you need to use a multimeter.
The diagnostic procedure is carried out as follows:
First of all, the black wire must be installed in the left hole.
Install the red cable in the middle.
Further, the device itself is turned on for diagnostics. The multimeter must be activated in the blue twenty mode.
Now you need to carefully short-circuit the test leads of the multimeter.
In the event that on the display of the device the arrow points to zero, that is, zero resistance, this indicates that everything is in order with the high-voltage wires. This means that the problem must be looked for elsewhere. If the needle of the multimeter on the dial points to one, this indicates that the resistance level is high enough and exceeds the norm. In this case, you can understand that the problem lies in a particular wire. Most likely, he is interrupted or he has poor contact. In order not to engage in repairs, the best option would be to purchase a new wire and install it.
When repairing wires, you need to use not only electrical tape, but also corrugation, it is more resistant to rubbing than electrical tape.

After buying a new car, the question arises of how to protect the car from theft. The first thing that comes to mind is setting an alarm, and
Does the ignition not turn on on the VAZ 2110? One of the causes of the disease may be in the ignition. Do not rush to change the ignition lock to a new one, first try to check it with your
Yesterday I bought a euro panel and the first thing the question arose was how I, using my old wiring, install a panel on which there are buttons from VAZ 211415.
Technical characteristics of the generator
The tenth VAZ family has a number of powerful consumers, such as:
Headlights (near, far, PTF); (current strand 9A - BS or DS or PTF)
· Windscreen wipers and washers: front and rear (8-12A);
Heated rear window (8-12A);
Interior heater fan (up to 15A);
Heated seats (did not measure due to
A useful revision of minimal complexity.
A brief background of the problem: an alarm was installed on a new car (2008) during pre-sale preparation (Sheriff 725, but we will not be talking about it). In the driver's door, the usual actuator is replaced with a 5-wire one. Trunk lock control channel connected.
On a new machine, almost immediately installed a glass closer from Sheriff PWM-200 ... At that time, there was not much choice. Either primitive - "close only", or - full-featured PWM-200.
From the experience of operating the VAZ (first the classic 21011, then 2111), it has long been noticed that very often the ignition switch contacts (ZZ) that control the starter retractor relay burn out and become unusable. The current through these contacts reaches 20A. We have to replace the entire contact group. So I decided to fix this problem on a new typewriter right away, without waiting for it to appear.
A lot has been written about the rather unsuccessful and dim taillights of the VAZ-2111. This problem becomes especially urgent in sunny weather. Repeatedly noticed that from the signaling the turns blink somehow livelier and brighter! So I decided to measure everything in detail.
I came across a reference - how to make an adjustable pause at the front wipers in a simple and affordable way. It is enough to install a variable resistor in the gap of the yellow-green wire connecting the Terminal “J” of the relay (pin Ш4.10) with the steering column switch (pin. J). Variable resistor 22kOhm - a pause is obtained from 1 to 30s with smooth adjustment.
I came across an interesting revision of the power supply circuit of the ignition module (MZ).This revision can be applied to both the MZ and the IKZ.
In short, the power circuit of the ignition module is not made in the best way. There are ripples and voltage dips, which negatively affects the quality
The purpose of installing this device is to reduce engine overheating in warm seasons when driving in jams, traffic jams, etc.

The speed sensor connector collapsed and began to lose contact. Because of this, the speedometer needle jumped arbitrarily. Sometimes, the speedometer needle simply fell, and you had to go under the hood and juggle the connector.
A wiring diagram is used to combine all electrical appliances and equipment in a vehicle. If any of its elements fails, this may affect the functioning of the car as a whole. More similarly, you can learn from this material what the VAZ 2111 wiring diagram is for an 8-valve injector and what malfunctions are typical for it.
First, we propose to figure out which systems and assemblies are used in the wiring diagram.
Battery. This device is designed to ensure normal engine start and power supply to electrical appliances and equipment when the engine is not running. If the battery is discharged, it will not work to start the engine with the key; you will need to either try to start from the "pusher" or "light up".
Starter. The purpose of this unit is to provide the ignition system with a high-voltage pulse required to ignite the combustible mixture in the internal combustion engine cylinders.
The generator is one of the essential components of any electrical system. This node is necessary to power the electrical devices and devices of the vehicle while it is moving. In addition, the generator allows you to charge the battery, replenishing its charge, which was used to start the engine.
Ignition switch.
Mounting block with fuses. The purpose of fuses cannot be underestimated - these devices are used to ensure the protection of car electrical circuits. If voltage surges occur in the electrical system of the engine of the 16 valve injector, then it is the fuse that will fail first, thus protecting the equipment from damage (the author of the video is the Autoelectrician HF channel).
But these are only the main components of the system, as for the complete wiring diagram, it includes various nodes and systems:
connecting the starter unit;
contactless ignition system;
ignition switch connection diagram;
lighting system, which includes the optics of low and high beam, brake lights, side lights, fog lights, turn signals, as well as lighting in the car interior;
wipers activation system, as well as a windshield and rear window washer;
sound signal activation circuit;
power window activation system;
activation of the ventilation device of the cooling system;
luggage compartment lock;
rear window heating unit;
the instrument panel, which displays all the main instruments of the car, the status of the sensors, the speedometer, the tachometer;
stove automatic control system;
generator unit connections;
control of the power unit.
As you can see, in general, the electrical diagram of a VAZ 16-valve engine is a rather complex system. Accordingly, there are also enough breakdowns in its work, all of them can be conditionally divided into several groups.For example, if you have suspicions about the functionality of the spark plugs, but they turned out to be working, then you need to check the operation of the ignition coil and high-voltage cables. As practice shows, breakdowns in the wires can also lead to incorrect operation of the ignition system. Failure of one or another element of the electrical network can be the result of both a breakdown of the device itself and the failure of a generator unit or battery.
Most often, car owners are faced with the problem of battery failure, therefore, we will consider the main malfunctions characteristic of this device:
a short circuit has occurred between the electrodes of the device;
damage to the plates located inside;
the appearance of cracks and other mechanical damage on the battery case, as well as sprinkling of the plates, which can lead to leakage of electrolyte;
oxidation of the battery terminals, this problem can be solved by stripping.
All these malfunctions ultimately lead to battery discharge. If we talk about the reasons that caused these problems, then most likely they all lie in improper operation, of course, if the battery life is high and has not yet ended. Much less often, the malfunction lies in a factory defect, but this does not happen often.
In order to prevent malfunctions in the operation of the battery, the following rules should be taken into account during operation:
First, the device must be securely fixed in place. If the battery is not securely fixed, this can lead to constant vibration, which can subsequently cause the appearance of cracks on the case.
Car operation and, accordingly, the use of the electrical network is allowed only when using a working generator. If the alternator malfunctions, or its belt is too loose, this will ultimately lead to the discharge of the battery.
In the event that the contact at the terminal of the device is poor, this can lead to its oxidation and destruction.
The battery discharge is also facilitated by prolonged cranking of the starter when trying to start the engine. Especially often, this problem manifests itself in frost, when the battery electrolytes are less mobile, and the driver has to turn the starter longer to start it (video author - Vyacheslav Kravchenko).
Depending on the type and manufacturer, the battery can last anywhere from three to five years. However, the service life may be lower if the battery is used in intensive mode and in harsh conditions. One way or another, the consequence of a discharge of the battery is always the same - the device will not be able to crank the starter to start the engine, as well as power the devices and equipment of the car as a whole. In the event that the diagnostics showed that the battery is working normally, it is possible that the cause of the malfunction lies in the operability of the generator.
Its design as a whole is more complex, respectively, this node has enough faults:
abrasion of the brushes, which is due to their wear;
breakdown of the voltage regulator relay;
failure of the diode bridge;
bearing wear, which is accompanied by a hum when the generator is running;
wear of slip rings;
damage or wear of the pulley teeth;
short circuit in the stator winding;
damage to the charging circuit wiring;
breakage or wear of the alternator belt.
Malfunctions in the operation of the unit can be determined by diagnostics using a multimeter. As for the repair, you can do it yourself. Earlier, we have already described the procedure for repairing a generator using the example of the VAZ 2114 model in this article, in the case of the VAZ 2111 it looks similar.
As for the rest of the faults in the operation of the electrical circuit, there may be several reasons:
failure of the device itself;
blown fuse caused by a short circuit (before replacing the fuse, it is necessary to determine the cause of the short circuit);
open circuit, the problem is solved by replacing the wire;
oxidation of contacts on device terminals (video author - Ramanych channel).
In order to prevent problems in the operation of electrical equipment, it is necessary to follow certain preventive measures, in particular:
Recommendations for repairing wiring in a VAZ 2111 car are given in the video (author - Wolos FromG channel).
Electrical wiring plays an important role in the car. The correct operation of the main devices and systems, as well as the car as a whole, depends on it. Today we will consider the basic wiring diagrams of the VAZ-2110 family.
The VAZ-2110 wiring is of two types: carburetor and injector ... There are slight differences in them, but the basic principles of operation and wiring are the same. By location, the wiring differs in: engine compartment and salon ... All electrical equipment of the car is connected using wires of a certain color. To each element through the pads, fuses, there is its own wiring harness.
The voltage of the on-board network is 12V constant, minus on the car body.
Having a wiring diagram and knowing the principles of operation of the main components of a car, it is not at all difficult to find a malfunction and the cause of its occurrence.
Before starting the repair of the car's electrical wiring (if this is not related to troubleshooting), the terminals should be removed from the battery (accumulator).
On the first releases of the VAZ-2110, a carburetor was installed, which was later replaced by an injector, as a more modern and reliable system that ensures economical stable engine operation. The wiring of an engine with a carburetor includes almost the same life support systems for a car as with an injector.
A - the order of the conditional numbering of the plugs in the pads of the mounting block, B - the order of the conditional numbering of the plugs in the blocks of the sensor-distributor
Notes: 1. In the wiring harness of the instrument panel, the second ends of the wires of white, black, 2. The bends of the wires at the entry points of the bundle show the directions of their routing.
The carburetor is already an obsolete part of the car. It is both less reliable and unable to provide such an accurate supply of the fuel mixture. In later releases, the carburetor ignition system was replaced with an injection one. The controller in this system "reads" the operation of all systems, thereby defining and setting many indicators - calculating the fuel mixture, etc.
Finding a wiring malfunction must start looking in the contacts. Moreover, you need to check all the wires that are included in the harness: their visual integrity, resistance, reliability of contacts, etc. The engine compartment wiring has identical plugs.
In addition to the wiring that is provided for the VAZ 2110 carburetor, the "dozen" injector is also equipped with a number of fuses that protect almost all of it from the possibility of short circuits. The fuse and relay box in VAZ-2110 vehicles is located in the passenger compartment near the driver's seat, to the left and below the steering wheel.
Structurally, fuses are not provided only for supplying current with a wire from the battery, in the starting and ignition circuits, as well as for the wire going to the generator.
To replace a defective fuse, first find the one that has blown and be sure to fix the cause. After that, install a new one of the same denomination.
Do not replace fuses with jumpers because of this, blocks and devices may become unusable, as well as a fire in the wiring!
K1 - relay for monitoring the health of light bulbs;
Although domestic cars will be simpler than foreign cars, they all consist of a huge variety of different components, power and fuel units and, of course, sophisticated electrical equipment. Not without a modern electrical part and in such a familiar VAZ-2112. The right turn stopped working, there is no dipped headlights, the horn is silent and does not buzz, a light bulb in the trunk has burned out or the radiator fan has stopped turning on. What to do, where to run and who to ask?
Every car owner should get acquainted with the electrical part of his car at least in general terms. Where to begin? Rummage in the glove compartment, and if your wife has not yet put things in order, you can find there the "Manual for the operation of the car VAZ-2112". Among other things, this necessary book contains a lot of important information on the electrical part. Having penetrated a little, in the future you will not only save on repairs at the service station, but also avoid ordering a tow truck, when suddenly your "beloved" will be rooted to the spot in the middle of the field.
The machine and its electrical circuit cannot exist separately, this union is inviolable, like the foundations of the Chinese wall.
Almost all systems, one way or another, depend on electricity and in the absence of it, they not only refuse to work correctly, but do not function at all.
Here are just a few of these interactions:
ignition of the combustible mixture in the fuel system of both carburetor and injection types of the engine;
supply of electricity to the starter when starting the engine;
instrument panel illumination at night;
informing other road users about the desire to carry out a maneuver using a light indicator "to the right" or "to the left";
playing a sound signal to prevent an accident;
turning on the side lights to identify the car at night.
We turn to the wiring diagram itself.
Among other things, the presence in the "Manual" of printed electrical diagrams with detailed descriptions makes it an indispensable assistant in not only accurately determining the symptoms, but also "prescribing treatment", finding out the most important question of why it hurts, and not just where.
It is important to understand according to our diagram what the following auxiliary equipment is connected to:
sound signal;
wipers;
radio or radio;
interior lighting;
heated rear and front glass;
power windows (if available).
The task is important for the reason that in the car there is a certain interdependence of some (main) systems from others (auxiliary). Some work in pairs, while others work in threes or even four. If you know this connection for sure, you will immediately find your way. If there is no current supply to the glow plugs, then, most likely, other subsystems working in the same bundle are not functioning for you either.
Battery. The battery is a set of usually 6 modular "cans" complete with special lead plates and immersed in an acidic environment.
usually short-term supply of voltage to various systems, even with the engine off;
starting the engine by ensuring the unhindered supply of the required current power to the ignition systems.
Generator. The device is vital for taking over the baton from the battery after starting the engine.Provides all systems with the necessary power and even recharges the battery while the car is moving. It copes with the task best with a warm engine.
Ignition system. Provides the ability to ignite the fuel mixture in the heart of the car - the engine cylinders. In modern models, including the VAZ-2112, a system is used that makes it possible to have a contactless method of igniting fuel, which replaced the contact one, which is outdated at the moment both morally and technologically.
Let's pay close attention to the merits of this modern method in order to fully understand how it works:
great strength and retention time of the electric charge;
Glow plugs have a longer service life;
the connections on the contacts remain in working order for an infinitely long time;
the motor starts quickly and evenly;
the car has great starting power and fuel economy;
the fuel mixture burns more efficiently.
This problem occurs due to the fact that the battery charge is disappearing somewhere. It does not disappear by accident, but always for some reason.
you leave the car on the street at an ambient temperature of -20 degrees and below;
the battery life is running out;
for some time in your cabin the radio remained on, which led to a loss of charge power.
In all these cases, two types of treatment are usually used: first, to urgently recharge, and secondly, to buy a new battery. If you pull and drive on a discharged battery, then soon you will not even be able to remove the car from the alarm. You will have to manually remove the terminals, trying to silence it. The situation will immediately improve as soon as the battery is charged again.
see if everything is ok with the generator. Whether it is well worn or sagging. This procedure must be done with all versions of the fuel system, both carburetor and injection. It is also not decisive whether you have a standard equipment or 16 valves;
we check the fuses on the VAZ-2112 according to the electrical equipment diagram, which we talked about above. The underside of the safety box cover will also be of great help. There are clues that the diagram will help to decipher. Replace the burnt element and try to start the car again. If the light goes out, then we have solved the problem;
if the red light on the dashboard does not diminish, you need to check if the battery terminals are tight, if they are oxidized. Is the wire from the battery to the alternator and starter damaged?
These are some recommendations for eliminating widespread difficulties associated with a malfunction of the electrical networks of the VAZ-2112 car with 8 or 16 valves. Of course, it is not possible in this overview to investigate all faults and provide information on how to fix them. For example, where to look for the cause of de-energizing "turn signals" or pumps that ensure the stable operation of the vehicle.
It's great that the cooperation of car enthusiasts and their timely tips help save time, money and hassle when the car needs to be repaired.
