VAZ 2114 or as it is called "fourteenth" - a car of the Volga Automobile Plant. This model was created on the basis of the VAZ 2109, but has a number of transformations: restyling of the front of the body by adding headlights, a modified bumper, moldings were added. The first car was produced in 2001, global production began in 2003. The electrical circuit of the VAZ 2114 has minor changes compared to its predecessor, the "nine".
Scheme of electrical equipment VAZ 2114
The main electrical equipment of the VAZ 2114:
Generator
The machine is equipped with a 3-phase generator alternating current with a voltage regulator and a rectifier unit (a device that converts D.C. to a variable).
Consists of the following elements:
- Covers with special holes for bearings;
- Brushes, which are a kind of non-separable unit;
- Winding;
- The core cylinder, inside which the winding is laid;
- Blocks of diodes (6 power and 3 additional);
Starter
This is an electric motor. It contains 4 magnets that provide excitation of the device.
Its main malfunctions are: the armature does not rotate or has a low rotation speed, the relay does not work or works repeatedly and turns off, the flywheel does not rotate, unusual noise is heard when the armature rotates.
Door and interior electrics
Part of the electrical equipment of the fourteenth model, like any other car, is located in the doors. The electrical circuit of the VAZ 2114 includes the electrics of the doors and is represented by the following elements:
- Seat heating;
This is an additional option, not included in all vehicle configurations.
- Electric windows;
This option is also not present in the standard (empty) model.
- lock locks;
Lighting and signaling
The electrical equipment of the VAZ 2114 is represented by the following lighting fixtures:
- headlights;
- Fog lights;
- Outdoor Lighting;
- turn signals;
- Electric motors
- The cooling fan is a DC appliance. In the event of a malfunction, it is not repaired, but immediately replaced with a new one.
- heater fan
This is an electric motor. Excitation occurs through permanent magnets. The resistor helps to achieve a lower speed. As in the case of the previous one, the faulty device is not repaired, but replaced with a new one.
Scheme of electrical equipment vaz 2114 injector. Devices
The electronics are similar on cars VAZ 2114, the fifteenth model and Lada Samara 2. The electrical circuit of the VAZ 2114 injector 8 valves includes the following devices:
- Speedometer;
- Distance meters;
- Lamps (Control and illumination of the instrument scale);
- coolant t sensor;
- Gasoline pointer;
- Time indicator;
Information from the sensors comes to the module, which is responsible for the operation of all devices.
Electronic devices are not subject to repair, spare parts for them are not produced. Only lamps (pilot and dial illumination) can be replaced. 
Electrical equipment vaz 2114 injector. Major instrument failures.
- Functioning of the sensor of level of gasoline or temperature is broken
Perhaps the cause is damage to the instrument cluster, a breakdown of the sensor itself, or, most often, damage to the wires. The sensor and combination must be replaced, and the condition of the wires must be carefully checked, if necessary, their damage must be repaired.
- The work of control lamps is broken
It is possible that the lamp simply burned out, its sensor is damaged, the wires are oxidized, or the contact is not tight enough. The wires, the sensor and the lamp itself must be replaced, and the contacts can be bent to ensure a tight hold.
If you find an electrical problem in your car, do not try to fix it yourself. Contact a professional auto electrician. When choosing a car repair shop, do not focus only on price, study the market, read reviews and make an informed decision. Imaginary savings can later result in more serious repairs and, accordingly, more significant financial costs.
We hope that in this article you have found answers to your questions and the electrical circuit diagram 2114 has become more accessible for understanding.
Domestic-made cars VAZ 2114 are a more modernized version of the legendary "nines", which for a long time were sold not only in the Russian Federation, but also in European countries. The electrical circuit in these cars has also undergone changes. In this article, we will talk about important changes and breakdowns of the equipment system.
Peculiarities
VAZ 2114 cars have many innovations compared to 2109, in particular, this applies to electrical wiring.
Whether it's an injector or a carburetor, the 2114 is in:
- vehicle interior;
- in the engine compartment;
- behind the car body.
It should be noted that the carburetor VAZ 2114 was produced only from 1997 to 2000, then they were equipped with carburetors from the VAZ 2108.
But new engines have a more powerful ignition system, respectively, the electrical control circuit is also characterized by certain features, for example:
- A new harness has appeared for connecting to the terminal. This component, through high-voltage wires (BB), sends signals to the candles.
- Another harness has been added to mount the switch.
- There was an additional wiring designed to connect the adsorber valve to the injection system controller.
Many VAZ 2114 car owners mistakenly believe that thanks to the ignition module, you can not use the coil. In fact, this device is equipped with two coils and two switches. One of the coils transmits a signal to the first and fourth cylinders, and the second - to the second and third.
The equipment system of VAZ 2114 cars with an injector engine has undergone certain innovations, not only due to the addition of new electrical equipment, but also as a result of the modernization of the car as a whole:
- it is possible to mount the device;
- it is possible to connect the heating system of the front seats;
- VAZ 2114 car owners can install PTF, etc.
Engine compartment
In order for the VAZ 2114 with an injector engine to operate on a lean combustible mixture, the machine is equipped with:
- forced gasoline injection system in each individual cylinder;
- connecting an improved ignition system, characterized by higher power;
- added ECM - .
As you know, to ignite a lean combustible mixture, there must be a more powerful spark transmitted through high-voltage explosive wires. A spark is transmitted through the explosives of the VAZ 2114 injector when the piston is located at top dead center. Such a control scheme was implemented due to the installation of the module.
The principle of operation of the device is as follows:
- to generate a variable electric current a generator is used;
- the current passes to the control unit, where it is converted to direct;
- further, the current is supplied to the coil windings in accordance with the control scheme;
- the secondary winding begins to generate high voltage for transmission through high-voltage BB wires;
- then, through the same high-voltage wires of explosives, the voltage passes to the spark plugs.
Salon
As for the interior, the manufacturer in the VAZ 2114 replaced the center console, which has certain differences:
- in the upper part there is no longer a glove box, it is installed below;
- the dashboard was replaced;
- appeared in VAZ 2114 on-board computer.
As a result of such changes and the replacement of old elements with new ones in the VAZ 2114 with an engine, the injector has changed and:
- there was another harness for connecting the on-board computer;
- added a temperature level sensor outside the window, which is mounted in front of the radiator;
- a voltmeter relay has been added.
In addition, another block of wires for was added to the control circuit.
Main malfunctions
If malfunctions occur with high-voltage wires of explosives or wiring in general, this will be reflected:
- on the operation of the engine - the unit will not be able to operate at full capacity;
- on the operation of the equipment;
- on the work of optics and other systems.
In general, wiring faults are divided into several types - breakdowns of the ignition system and sensors. Depending on the type, the diagnostic procedure is also determined. In order for the order to be correct, you first need to understand the type of malfunction.
Ignition breakdowns
Symptoms of injector control circuit problems that will help determine the course of action:
- loss of motor power;
- the appearance of dips in power when you press the gas;
- unstable idling;
- incorrect operation of one or more cylinders.
The procedure for detecting a breakdown begins with diagnosing the presence of a spark of explosive wires:
- the ignition is switched on;
- from the BB of the wire of the first cylinder, it is necessary to dismantle the tip;
- the tip must be brought to the metal, but not pressed (the distance between the tip and the metal is about half a cm);
- then the starter turns on and you check if there is a spark, a similar operation is repeated with all the candles (the author of the video is Domashny automaster. Car repair.).
If there is no spark, you need to look for problems in, the procedure is as follows:
- the coil is diagnosed;
- the module is checked;
- then you need to check the control unit.
In this case, resistance is measured. A tester is used to diagnose coil resistance. You need to measure the resistance of the primary as well as the secondary windings. The resistance level should be correct, if the resistance is incorrect, it may be necessary to replace the windings.
As for the diagnostics of the module, it is also performed using a tester - you need to measure the resistance on paired BB wires. The resistance level should be 5.4 kOhm. If the resistance is different, then you have found the cause of the breakdown.
Sensor failures
As you know, cars of this model are equipped with multiple sensors, the failure of which can also cause unstable engine operation. Since the wiring in the engine compartment can lead to problems in the operation of the unit, before changing the sensors, you should try to move the pads and connectors. Perhaps the problem lies precisely in a bad connection.
Most of the regulators can be checked using a tester, as a rule, the Check lamp on the control panel reports the failure of the sensors. As for such regulators as idling and mass air flow, you can find out about their failure after diagnostics, which is performed by the shutdown method. In the event that the engine does not start at all, you need to check the crankshaft sensor.
Video "All you need to know about wiring"
In the bulk, all products of the Volga Automobile Plant are tightly based on one platform. Today, the designers have made some variety, but at the time of the release of the VAZ 2114 it was the platform of the eight, which the plant courageously developed for twenty years in a row and completed and modified for another fifteen. An incredible number of phantom modifications that are built on the basis of the eight, differ in headlights and door handles, several engines and, perhaps, everything. But we, as their owners, are pleased to consider the fact that they are still different. Therefore, today we will consider the electrical circuit of model 2114 and its characteristic features.
Scheme of electrical equipment VAZ 2114
We managed to find an excellent authentic factory wiring diagram for the VAZ 2114, which we are pleased to present for study. The scheme is clickable and has a good resolution.
The scheme can be useful in many cases, but mainly when modifying and reworking some elements, which we will talk about.
Characteristic features of electrical equipment VAZ 2114
The VAZ 2114 car is a light modification of the VAZ 21093, which in turn is an improved nine, and all of them are built on the VAZ 2108 platform. This is how the genealogical tree of the model can be described in a nutshell. The model is distinguished from the nine by a new front panel, instrument panel, power windows, and a deeply improved stove. All this unbridled variety could not but be reflected in the electrical circuit.
First of all, this affected the scheme of the ignition system and the engine power system. In 2007, a modernized engine was installed on the car, which met the strict Euro 3 standards, and it was called VAZ 11183. The engine had a one and a half liter volume at first, and then it was increased to 1.6 liters. Also, a new injection system was installed on the car, which entailed some changes in the general scheme:
Also, as can be seen from the diagram, it was redesigned and brought into line with the new elements of the system.
Additional features of the new electrical system
The scheme has undergone changes not only in a constructive way, to ensure the operation of the new previously named elements, but also to allow the installation of additional equipment, which the owners of the first 2114 did not even know about. Initially, the scheme provided for:
Recent changes regarding foglights already took into account the need to connect them together with parking lights, so if you decide to install fog lights on the VAZ 2114, then you just need to study the diagram that we presented on the page and use it wisely. Moreover, without making surgical changes to the basic electrical circuit.
Power system and ignition system
The updated engine has a new injection scheme, which is why some new devices had to be applied, as well as to replace the ignition coil with a more productive and adapted to Euro 3 conditions. In order to comply with them, the engine had to minimize the amount of CO at start-up. And for that it was necessary to deplete the mixture. Since the poor mixture ignites worse, it needed a more powerful spark for the flash. This explains the use of a coil of increased power.
Changes have also been made to the interior. Cosmetics did not affect electrical equipment much, but dashboard has been completely redesigned. Power windows were also installed, a hint of an on-board computer. It could show the temperature of the air overboard if your radio with a weather forecast was not working, and also gave an idea of \u200b\u200bfuel consumption. This also introduced some complications and additional wiring harnesses, which are shown in the VAZ 2114 electrical diagram.
In the process of research, we together established all the features that distinguish the 2114 scheme from other related modifications, and the scheme will help to sort out possible problems. Learn materiel, and good luck on the road!
What to do when the light suddenly disappeared in the cabin of the VAZ-2114? Many motorists will say - go to an electrician and let him figure it out. But we will try to find the cause and methods of elimination when the interior lighting is gone ourselves.
Why the light in the cabin is not on (main reasons)
The scheme of the electrical equipment of the car, which must be studied before starting work
Car interior lighting is part of the electrics, and therefore, in any case, it is worth looking for a problem in this part of the machine. Of course, it is recommended to study, at least superficially, the technical diagrams of electricians in order to be at least a little in the subject. .
So what do you need? Detailed scheme car electrical components, a little ingenuity and a minimal set of tools. Consider the places where the problem may be hiding:
- Bulb.
- Plafond.
- Fuse.
- Wiring.
We fix the light and get acquainted with the electrician
Since the main points of failure have been identified, you can safely go directly to the methods for solving the problem. It is worth noting that with automotive electrics - not everything is so simple, but since this is a VAZ-2114, everything can be said very clearly here. Let's move on to problem solving methods.
Bulb
The first thing to check is the lighting lamp, since it is its burnout that can cause the light to go out in the car.
In order to get it, you have to remove the cover of the ceiling. After that, you need to check if there is a glowing filament, and insert the lamp into the control and measuring device or simply connect it to the battery. If the lamp lights up, then the cause of the malfunction is not in it.
Plafond
The problem may be hiding in the ceiling
Repeatedly, the ceiling itself became the cause of the malfunction, where it simply melted contact Group and shorted out, causing a blown or blown fuse.
To diagnose it, you will need to dismantle it from the car and visually inspect it. It is also recommended to ring the contacts coming from the lamp to the wiring.
Fuse and relay on the VAZ-2114
Replacing the fuse may solve the problem
The next reason is blown interior lighting fuse. This part can burn out due to a short circuit, which for various reasons occurs in the on-board circuit. Often the closure is caused precisely by a malfunction of the ceiling.
The interior lighting relay is marked with an arrow. Often the contacts burn out and do not allow the light to turn on.
Wiring
A broken wire could cause a malfunction.
Electrical wiring is a nightmare for any car enthusiast. One understands everything, but for others it is a “dark forest”. So, in the process of diagnostic operations, it is necessary to ring the wires going from the ceiling to the power or button.
conclusions
There are few reasons for a malfunction of the interior light in the VAZ-2114, and every novice motorist will be able to determine the cause of the malfunction. It is worth remembering that if the motorist is not sure that he can deal with the problem, then it is best to contact a car service.
The VAZ 2114 car is the final stage in the development of the 2193 model. The plant did not make any special changes to the design of the car, however, there were still some differences. In particular, this concerned the electrical circuit. Let's talk about the features and characteristic malfunctions, as well as methods for their elimination today.
Scheme of the on-board electrical network VAZ 2114
VAZ 2114, the electrical equipment diagram of which is presented in this section, has never been difficult to repair, for which it received certain sympathy from the public. The factory circuit itself is shown below.
The circuit is simple and not much different from other wiring diagrams of the first front-wheel drive VAZ cars. However, there are a few points that may require further clarification.
Self-repair of electrical equipment VAZ 2114
The simplest malfunctions that can happen to the electrical equipment of the VAZ 2114 may well be eliminated with your own hands. Some even without special equipment. Here are just a few examples of the most common breakdowns and malfunctions.
If the battery is discharging too quickly, it is worth checking the charging voltage at its terminals. To do this, start the engine and use a multimeter to take readings from the battery terminals. Normal battery charging current is 12-14 volts. If the voltage at the terminals is Idling engine is less than specified, then the battery will not be charged to the nominal value. The reason for this can be both tired and relay-regulator. To begin with, it is worth checking the tension level of the alternator drive belt. If the belt tension is insufficient, then at high speeds or in wet weather, when moisture gets on the drive belt pulleys, the belt may slip, and then the generator speed will not be sufficient to ensure that the battery is fully charged.
In the event that the belt tension is correct, and the battery does not receive the appropriate charge, the relay regulator may be to blame. The task of the relay-regulator is to control the voltage at the output of the generator. The car engine can operate at different speeds, and depending on this, the output voltage also changes. The relay stabilizes the voltage and provides constant charging current to the battery. The failure of the relay is dangerous because at high speeds, electrical equipment that is highly sensitive to voltage drops can be damaged.
Checking the relay is pretty easy. If the voltage at the output of the relay is unstable and, depending on the engine speed, varies by more than 12-14 volts, the relay is most likely broken and needs to be replaced. It cannot be restored.
Ignition module VAZ 2114
The ignition module is an important and critical device in the 2114 ignition system. If it fails or becomes unstable, the following symptoms will appear:
- unstable idle speed;
- failures when changing engine speed;
- the second and third or the first and fourth cylinders may not work in pairs.
If the first three signs can sometimes be attributed to an incorrect ignition setting, then a paired failure in the operation of the cylinders only indicates the failure of the coil.
The principle of operation of the ignition module and its tasks are the same as those of the ignition coil, only the module still distributes high voltage current between the cylinders. It supplies spark in pairs to 1/4 and 2/3 cylinders. In more finely organized ignition systems, each cylinder has its own coil, but the 2114 module is also able to provide spark to the cylinders in their firing order - 1-3-4-2. When working with the ignition module, it is important not to confuse the wires. The desired cylinder is marked on the module body, so if you are careful, the error is excluded.
The ignition module cannot be restored, so you need to check it for performance especially carefully. If the device shows signs of incorrect operation, then the computer issues the corresponding error codes: P0351 indicates that the coil of the first and fourth cylinder is not working, and P0352 indicates that the coil of the remaining two cylinders is not working. You can also check the resistance of the coils for insurance. If they are working, then at the input of paired cylinders (1-4 or 3-2), the ohmmeter will show 5.4 kOhm. Otherwise, the module has served its purpose. A new device costs about 1000 rubles.
We touched on only a few malfunctions of the VAZ 2114 electrical wiring system. The rest will be helped by the diagram above and intuition, without which any repair is impossible. Good luck on the roads!
