Central locking on the VAZ 2110. The central locking of the VAZ does not work

For many years now, motorists around the world have been complaining about a malfunction of the central lock and often wondering: “Why is this happening, and what are the reasons for this”? Answer to this question, can be obtained in a detailed examination of the very principle of operation of the central lock and its capabilities.

It is known that almost all modern machines have a special automated system, which allows you to open the car door and close it, just by pressing a button. This is the central lock, and as it turns out, some problems may arise due to its autonomy. This dilemma did not bypass the domestic VAZ 2114, which for many has long become indispensable.

The principle of operation of the central lock

To begin with, let's figure out what is the principle of operation of the central lock on the VAZ 2114? The operation of the central lock involves the transfer of signal control to a certain point, followed by activation of the relay. As a result of this, when you press the button on the key fob, the car door will be closed, or vice versa - open. A simple enough explanation.

However, this is enough to highlight the first central locking problem that everyone deals with. This, as you might guess, is a technical issue. In other words, internal state devices.

As we already know, central locking is controlled according to the principle of transmitting a control signal from point A to point B. This is where the snag lies, which is explained for a number of reasons.

• incorrect installation of the device or incorrect setting;
• climatic impact.

Troubleshooting options

The problems seem serious enough. But do not rush to be upset. Knowing these reasons, you can ask yourself the question: “Why does the central locking on the VAZ 2114 not work? What is the problem?"

To get started, you need to self-diagnosis, which will determine the next action. If the car makes the sound of closing the doors, but nothing happens, then you should unscrew the latches from the doors, and then lock the car. If the doors close individually, you should buy new ones with the appropriate diameter for repair.

An excellent tip would be to check the internal condition of the central lock. Often, the cause of the problem can be a dry coating on the wires. In this case, it is worth lubricating with machine lubricant and fixing the materials in the right places.

The remote control may have a weak charge. In this case, it is worth replacing the battery or, if necessary, the remote control itself.

Another type of problem has a slightly different character - inoperability, the fault of which is the climate. Instability in the operation of the lock, perhaps due to low temperatures, which lead to freezing of the signaling system. Or, which happens more often, water getting into the central lock of the VAZ 2114. This problem is simply solved by drying certain places of the central lock.

Helpful Hint: One of the most common central locking problems is dead batteries. Experts recommend changing them 2 times a year. The reason for the replacement may be incorrect operation from a distance of 4-5 meters.

Other system failure options

The above problems are the main causes of damage. However, there is a more complex mechanism, the defect of which cannot be ignored.

It happens that with the manual activation method, the central lock is not operational. In this particular case, the VAZ 2114 central lock fuse most likely does not work. Its condition depends on the ambient temperature. Due to hypothermia, there is a malfunction and it fails, as a result of this, nothing happens. The central lock does not respond to signal impulses. Another reason is the high temperature, which leads to a short circuit.

Fact: Often, the central locking works intermittently in certain places. This is usually caused by electromagnetic interference.

Why did the VAZ 2114 central locking unit burn out and what to do

The solution to this problem is based on the use of a special apparatus - a multimeter. With it, you can check the voltage of those contacts that are responsible for activating the remaining doors. What to do if the central lock control unit on the VAZ 2114 does not work and does not show any signs of life? In this case, you need to make sure that it can be restored by first diagnosing its condition and, if necessary, restore or buy a new one.

The system that everyone calls the central lock is not installed on everyone cars VAZ-2110, but only on some of them. The purpose of this system is to simultaneously block the locks of four doors, when the driver, using the lock key, closes the left front door of his "tens". A similar picture occurs when the driver's door lock button is pressed from the passenger compartment.

There are several problems associated with the operation of the central lock on the "dozens". Firstly, the driver must be aware that in no case should a long or frequent impulse be given to control the opening or closing of the doors, as this can lead to failure of the activators that actuate the lock. They are located in each door of the VAZ-2110 car. With a long pulse, the activator motor collector heats up so much that the plastic brush holder melts and jams it. In this case, the activator will need to be replaced.

Second problem connected to the fuse that protects the electrical circuit of the central lock, because if it fails, troubleshooting usually begins with checking the integrity of this fuse. It is located in an inconvenient place, behind the fuse box in the passenger compartment. There it is very difficult to find it among the wiring harnesses, and it is tied to them with the help of electrical tape. It stands in a pink wire break and is enclosed in a plastic cup.

Another problem, on which the central lock refuses to work, is a plug connector, which is located under the carpet at the location of the driver's feet. Over time, moisture accumulates there and oxidation of the contacts occurs, due to which power is lost on the activator.

It is also possible failure of the module control unit a central lock, in which, using two relays, voltage is supplied to the activators to open or close the door locks. You can check its serviceability by applying voltage with battery on the pins of the module connector (white color, eight pins), to which the red or yellow wire is connected. If the locks work, then the module is faulty.

The central lock of a VAZ car for the owner is considered a fairly safe device. Keeping pace with progress, a person strives to be in time everywhere. This type of transport, like a car, has long become not a luxury, but a means of transportation. According to statistics, every second person drives a car.

Today, the products of the domestic auto industry are not in great demand, as foreign cars dominate the market. But not everyone can afford a foreign car. Therefore, people buy cheaper vehicles of domestic production. One of these cars is the VAZ 2110, 2112, 2114, which was distinguished by its stable performance, low cost of repair and simple operation.

The principle of operation of the central lock

The central lock is a system that, with a specific command, performs the function of opening or closing an object. For convenience, this operation is performed remotely. Some motorists choose the function of closing all doors after a certain period of time. It is very convenient for those cases when the driver does not have time or forgets to close the car door. As a rule, with the help of a remote control, you can control both the trunk and the hood, close and open the windows. The most common way to control the remote control is to press one button, after which all the locks on the car work. If the remote does not work for some reason, then you need to insert the key into door lock and turn it clockwise. If an accident occurs, the car's security system is activated automatically, all locks open. At the heart of the central locking mechanism there are incoming sensors located in the structure itself. These are microswitches and door switches (limit switches), actuators and a control unit. The limit switch must hold the position of the door, and this information must be transmitted to the control unit. Switches fix the structural part door lock. The cam device is equipped with the front door of the car. To fix the cam, the front doors are equipped with microswitches: there are two parts for each mechanism. Locking the lock forms one switch, and unlocking the second. There are two more microswitches used by the central locking mechanism. A fifth switch is installed on the lever device in the lock drive. It serves to determine the position of the door: when the door is open, the switch contacts close, the central locking system is deactivated. The electronic mechanism (unit) receives the signal from the microswitches and sends the information to the central control. In order to open an object, the central device sends a signal to certain control units, thereby activating the mechanisms in the locks.

Why the central locking VAZ does not work reasons

As we know, any equipment sooner or later fails. And the central lock on the VAZ 2110 is no exception. There are a number of problems that manifest themselves in the operation of this system. Many motorists inadvertently destroy the security system of the car. The driver must not give a long or rapid impulse to a request to open or close the door.

Scheme of the central lock on the VAZ

This action can disable the activator, with which the locking device works. When a long pulse is applied, the collector of the activator electric motor is very hot. In this regard, the brush holder begins to melt, and it may jam. After that, the activator will need to be replaced.

Protects the circuit of the central locking fuse. It is from him that they begin to search for a malfunction in the operation of the entire circuit. It is located inside the car, behind the fuse box. According to the scheme, it stands on the break of the pink wire (in isolation). Under the driver's mat there is a wire with a plug connector that accumulates moisture and oxidizes. Lost power to the activator. The modular block of the central lock can break. You should check its performance by applying voltage from the battery to the contact of the module connector. The gears of the gear activator are made of plastic. Such parts are subject to wear, and this is a mechanical failure. But most weak point the central lock is considered a solenoid, most often it is he who fails. The electromagnet is controlled via a switch. When opening and closing doors, the resource of solenoids is designed for approximately 10 thousand operations. After this number of switchings, malfunctions begin. The repair is simple: you need to replace the solenoid itself.

Installation of the central lock

When buying a VAZ car in a specialized car dealership, there is a possibility that the functionality of the basic configuration of the security system will be limited. That is, only doors (sometimes not even all) can be locked with a remote control or a key. For the safety of the car, drivers install alarms on all opening parts of the car. To do this, you can use the services of specialists from a service station, or you can do the installation yourself. If you know the schemes of the central lock and the operation of the electronic device itself, then you can easily put the lock on any part of the car. Specialists of different levels use the instructions when installing an alarm on a car. VAZ 2114 central locking schemes and security system installation rules are included with the alarm system. While a system as simple as central locking can fail, you won't find a driver who doesn't praise it. When purchasing a car, everyone looks at the package, which should include an electrical alarm (or central locking). Many cars do not have an alarm, but there is a central lock that was installed at the factory. There is no big difference, but the convenience of the presence of a centralized blocking system is appreciated. This is better than waiting for passengers to get out of the car, then close all the doors from the inside and close your own when leaving. It is convenient to press one button on the remote control so that all doors close / open at once.

There may be such a problem with the system when the battery in the key is dead. But this is not a very serious "trouble", which is solved by simply replacing the power supply. The scheme of the central lock clearly proves the simplicity and uniqueness of the device.

The central locking of the VAZ 2114 (hereinafter referred to as the CZ) is a mechanism that ensures the simultaneous closing or opening of all four doors in the car. This option is very convenient, eliminating the need to reach out and lock the doors manually each time. Such centralized control comes in handy when installing car alarm systems, which greatly expands the possibilities and variations in the use of the locking mechanism.

The operation of the lock itself does not depend on whether the car engine is running or the fact that the ignition is turned on. Power is supplied directly from the battery.
A fairly common situation is when the system malfunctions. For example, when the locks of some doors are closed, while others are not. Either the closing process occurs with great difficulty, jamming, partial failure of the latches. A situation familiar to many motorists, isn't it? There are several reasons for the incorrect operation of the node, we will dwell on them in more detail.

7 Common Faults

Why does the central locking of the VAZ 2114 not work, you ask?
Most often, interruptions occur during temperature changes, wet weather. The first signs are fuzzy operation of the lock, jamming or incomplete operation.

Below is a list of the top major failures:

Scheme of the central lock vaz 2114

The system consists of the following components:

• mounting block;
• 8 amp fuse;
• 4 gearmotors (one in each door, and the one in the driver's door has a contact group);
• central lock control unit;
• wires (red, black, blue, yellow) and plugs;
• traction, which are located in each door;
• limit switches that indicate the current state of the door (open or closed).

Where is the central locking vaz 2114

The central lock is located in the driver's door, as well as the electric drive. If we talk about the whole system, then it is distributed over 4 doors (in some cases, extends to the trunk), and the central panel (control unit).

Check and diagnostics

If your car is equipped with one of the alarm systems, then it is better to start diagnostic measures with it.
You should check the operation of the central lock when using the key fob, and when opening, locking with a key. If the central lock works correctly during a manual check, then the reason is the alarm.
Additionally, it would not be superfluous to check the battery charge level, since if it is insufficient, interruptions in the operation of many electrical consumers occur.
In general, the test is best done, as they say, along the path of least resistance. That is, diagnose something that does not require the use of significant effort. And if the malfunction cannot be identified, resort to disassembling the driver's door and examining the mechanisms along with electronics.

conclusions

In this article, we have touched on only some of the most common problems associated with the operation, repair and maintenance of a central lock. Despite the fact that the node has plenty of problems, restoring health is not a difficult and even more impossible task. Usually, to achieve uninterrupted, accurate operation of the system, only practical skills are lacking. After receiving which you will be able to repair any complexity!
