Central locking block diagram for VAZ 2110

Signal and central locking, VAZ-2110

This review discusses how to connect an alarm system to the central locking of the following cars: VAZ-21099, as well as 2110 and 2115. There are three standard connection schemes: for central locking controlled by negative polarity, positive and variable. But different cars have their own nuances. Sometimes it is necessary to add a fuse to the “+12 Volt” wire, sometimes, on the contrary, this is not required. VAZ locks, in turn, belong to the simplest type, the first. But the standard scheme published on the Internet is not suitable for them.

Features of the VAZ central lock

Everyone knows that the Lada models listed here use central locking controlled by negative polarity. This literally means the following: we apply “0 Volt” to one wire - all locks close. We apply the same voltage to the other wire (second) - they unlock. This is done in many European cars. What does it mean to “supply “0 Volt”? This means connecting the wire to ground.

Central locking control unit connector

The central locking control unit has the following wiring:

Black wire – ground (connected all the time);
Pink – power supply “+12V” (built-in fuse is used);
Yellow, red - connected to the actuators in the doors (these wires are not connected to the signaling system!);
Brown, white - control wires, just those that have already been mentioned.

Let's look at the central locking connection diagram, which is implemented “from the factory”:

Standard connection diagram for central locking

First, we may decide that the triangular connector (labeled “C”) is suitable for our purposes, since it contains control contacts. But please note that the standard circuit uses a microswitch located in the driver's door. We will break two wires coming from this switch, and the relays built into the alarm unit will be connected to the breaks. Other options are excluded.

conclusions

We briefly examined possible problems in the operation of the VAZ central locking system. Despite the fact that this device can break down with enviable regularity, especially due to the failure of activators, the maintainability of the mechanism and ease of maintenance are really high. You can be sure that in order to thoroughly understand and repair the automatic door opening and closing system on VAZ 2110 cars, you now only need a little practice.

Good day to all. In my last post, I asked you for help and advice on repairing the central locking system. Thank you all for your comments and responsiveness. Today in this post I will tell you how this problem was solved. So, initially the problem was that the car was armed, but the locks would not close. They also did not close by manual pressing. It was decided to take everything apart and look. During disassembly, I found out that the driver's door has a regular two-wire actuator, instead of the required 5-pin one. The remaining three contacts went to the lock itself; these were wires to the limit switch for the open/closed positions.

Well, everything seems to be working at this stage. I forcibly applied +12V to the actuator for a short time, for a short time, otherwise there will be an overload and it will either burn out or the brushes will close. He's twitching, which means he's alive. I went further to look for the reason. I thought that the wires might have frayed in the place where they enter the door. He pulled out the bunch, and for good reason. Some wires had broken insulation - I fixed it with electrical tape.

Let's go further, I read that there is a central locking control unit. We need to find him now. I opened up the floor covering to see where the beam went. As a result, I found the end under the heater on the driver's side of the connector and on it a circuit rewound with electrical tape. Even then I felt that there was probably a problem with it, but out of ignorance, I continued my search further.

As you can see, 6 wires come here. Pink 12V, black mass, white, brown, yellow, red - I described them above. Here is the entire detailed wiring diagram, the colors matched.

In the end, I realized that all the signals reach this block, there is power to it, but there is nothing at the output. So he's dead after all. Having gone shopping, everywhere they offered me an 8-pin block, and only on the fourth day did luck smile on me and I bought the original 6-pin central locking block for the VAZ 2110. It was immediately installed in its place, with bated breath I pressed the signal light - and hurray! closed, opened. Everything is as it should be!

Well, since I’ve already taken apart a lot of things, I’ve pulled up all the masses at the same time. I also found two free two-pin chips in the same place in the driver’s feet under the stove. Maybe someone knows what they are for.

Let's make the alarm system and central locking together

Any modern alarm unit is equipped with two relays connected to the central locking control unit. One relay is opening, the second is locking, and the circuit in the general case looks like this:

Control of central locking by supply of “mass”

In our case, the green and white cords coming from the signaling unit will be required, as indicated in the diagram. However, they will not be the only ones needed. We will connect the relay contacts to breaks in the standard wiring. This means there will be not 2, but 4 cords.

The cause of the malfunction of the central locking VAZ 2110

How quickly a person gets used to everything good. It would seem like a central lock

, such a small thing, but to what extent...

Operation of the central locking relay VAZ 2110

This relay can be used in any car, the advantages are ease of installation, as well as low cost of components.

Connection diagram for VAZ central locker

Take another look at the diagram published in the first chapter. We will connect the relay to the gap in the white and brown wires going from the microswitch to the central lock control unit. And it is obvious that it is easier to break these wires near the 8-pin connector. The same one shown at the beginning.

To avoid any questions, we will show you what should happen as a result:

Connection diagram, central lock VAZ

The common contacts are connected to the wires coming out of the microphone. The white cord continues with the brown wire coming from the door, and so on. Normally closed contacts are also used, along with normally open ones. These are the features of connecting to the VAZ central locking system.

An approximate sequence of actions performed by the installer:

Make and lay a 4-core cable running from the signaling unit to the 8-pin connector;

We have given this sequence to emphasize once again that the relays are switched on between the microphone and the central lock control unit. There is no need to connect any additional devices. As a result, the alarm system will be able to control the state of the locks.

Remember that installation is performed by removing the negative terminal from the battery.

All wires added to the car structure must be protected (use heat-resistant tubes or electrical tape). Twisting is not the worst method to connect two wires. But it's even better to use soldering.

An interesting nuance from practice

It would seem that if a person has experience working with electrical equipment, he can do everything according to the instructions given. As a result, if no mistakes are made, you may encounter an interesting phenomenon. Instead of closing, there will be a short-term locking followed by opening. And vice versa. What to do in this case?

Settings

After the alarm system on the VAZ 2114 is fully connected, its final configuration should be performed.

It is carried out as follows:

Disable security.
Set the ignition key in the lock to o.
Press the button labeled Valet 6 times in a row.
After the step marked “3”, immediately turn on the ignition (6 beeps should sound).
Using the Valet button, select the required function (their list is given in the table below). To set it to the required value, press the corresponding key on the alarm key fob.

In this case, the most optimal (recommended) settings will be the following:

for function 12 - value 3;
for function 11 - value 4;
for function 9 - value 3.

You can check whether the alarm is connected and configured correctly as follows:

Disconnect the yellow cord coming out of block A91 from terminal 15 of the ignition switch. Turn the ignition key and start the engine. Pay attention to the alarm LED - if connected correctly, it should blink continuously.

The last thing I would like to talk about today is the importance of correctly connecting the tachometer, which directly affects the operation of the autostart

To avoid errors, it is recommended to make this connection strictly in the following order:

connect the red wire from the BUBD connector to the positive 12 volt terminal;
connect the black wire of the 18-pin connector to the vehicle ground;
Connect the gray-black wire of the same connector to the wire coming from the tachometer.

If you then turn on the ignition, then if the tachometer is connected correctly, the alarm indicator will begin to blink evenly.

What kind of malfunctions can there be?

When closing the lock on the door, no other actions are noted. But if you even slightly need to try to open it with the key, the door can open immediately. The presence of malfunctions is immediately visible here. The main ones can be highlighted. The central lock opens and closes itself on a VAZ - this is a normal state of affairs, but if it is faulty

The contact does not open in the central locking drive

The contacts do not open in a timely manner, and this occurs due to the following reasons:

Traction control. Structurally, it works like this: the lock button and the drive are connected together. In this case, the rod acquires the wrong position, and there is no contact with the electric drive.
When the button touches part of the casing. The element is not lowered to the required depth in order to contact the electric drive and the traction. There are no signals to other doors.

If there are problems of this kind, you need to make sure that the position of the button is fixed at the very end. If this is not observed, then it is worth checking the casing and making sure that there are no scuffs, only then pay attention to the ideal, even and accurate position of the rod.

Fuse failure

If the central locking on a VAZ does not work, then the cause of this circumstance may be a blown fuse. If the driver tried to open the door, but this did not lead to the desired result, then you need to look at how the electrical circuit works, and more specifically, the fuse. This element can quickly fail and the cause will be not only a short circuit, but also even the smallest load.

Fuse failure

The location of the thrust when operating a car in winter results in an overload on the engine elements.

Violation of the integrity of the central locking wires

If the central locking on a VAZ does not work, this may occur as a result of a broken section of wires. This is the main reason, since the fracture is observed in those places where the load on the node is greatest. This place is the passage of the corrugation from the side of the door and the counter. When opening a car door, the main part of the load occurs in this mechanism.

Violation of the integrity of the central locking wires

It is easy to determine the location of the fault; you need to release one of the ends of the corrugated element in which the wires are concentrated inside the door, and then tighten one of the central locking wires. Their constructive connection is into a single bundle, and also next to each other.
After doing some simple work, a damaged wire due to damage or interruption will be easy to repair.
Once a fault within the circuit is confirmed, replacement will be easy. To do this, it is enough to cut out the faulty section and replace it with a new one; just twist the ends of the wires together and then insulate them.
If it is difficult to visually determine where the wires are broken, you can always use a multimeter. The device will accurately indicate the location of the fault and the owner will carry out repairs without any problems.

When the central locking unit burns out

On the VAZ 2110 the buzzer stopped working, the reason for this may be a break in the central lock, or more specifically, a burnout of its separate unit. To carry out troubleshooting work, you need to use a multimeter. In this way, it will be possible to determine the presence of voltage at the contacts.

About the operation of the central lock

Where is the central lock on the VAZ 2110 and how does it work? The purpose of the drive is not only for the lock, but also for transmitting a signal to the installed unit. Afterwards the commands are transmitted to other doors.

The multifunctional drive must have five wires, and additional contacts are needed to communicate with the car control. How to connect the central locking on a VAZ 2110, just use a simple diagram.

You begin to appreciate many things after they are gone. The same applies to the additional options of the VAZ 2110. Central locking (CL), for example, you can not notice as long as it works properly or you can do without it altogether. But you quickly get used to good things, don’t you? Therefore, when something that provides us with a comfortable ride fails, you immediately begin to rush around in search of answers “how to fix it.”

Central locking device VAZ 2110

VAZ cars are not least good for their high maintainability. Whenever something happens to your iron horse, you can almost certainly solve the problem yourself without the help of specialists at a service station. “Ten” was no exception in this regard.

As for the central locking system specifically on Lada 110 cars, this is really a rich topic for discussion. Ignorance of elementary circuits and the operating principle of the unit can confuse many motorists. However, servicing the mechanism is quite simple. And given the enviable frequency of its failure, it turns out that knowing “how” is simply vital.

MAIN PANEL ELEMENTS

The main place on the dashboard is reserved for the tachometer and speedometer, the fuel quantity sensor and the current fluid temperature in the cooling system. Let's look at the main symbols on the VAZ 2114 panel in more detail.

Tachometer

The VAZ 2114 tachometer is a pointer device, the signal to which is sent by the on-board computer of the fourteenth. The tachometer displays data on the number of revolutions of the crankshaft at the current time. The tachometer is divided by scales into 5 units, every second of which is digitized. The maximum numerical value of revolutions is 80.

To find out the actual engine speed when the car is moving, the tachometer indicator must be multiplied by 100. For example, if the arrow is located at 40, then the crankshaft is performing 4000 revolutions per minute.

The manufacturer has indicated a critical speed value, upon reaching which the engine of the fourteenth may fail due to excessive load. It is highlighted on the device with red shading; this value ranges from 6000 to 8000 rpm.

Under the tachometer there is an electronic window, which displays data about the current time and ambient air temperature.

Speedometer

The fourteenth has an induction dial speedometer, which is located on the right side of the dashboard. The speedometer is also divided into sectors, the division size is 10 kilometers. The maximum mark is 200 km.

The speedometer operates from a speed measurement sensor located inside the gearbox. It is worth considering that all induction speedometers, including the one installed on the fourteenth, have an acceptable error level of 5 km/h.

At the bottom of the speedometer needle there is an electronic screen on which you can see data on the total mileage of the car and the mileage from the last starting point. The driver himself can set the starting point; for this, under the number 200 on the speedometer there is a manual switch that resets the current mileage count to zero.

Gasoline quantity sensor

On the right side of the instrument panel of the VAZ 2114 (the instrument panel of the VAZ 2114 and the designation of the indicators on the instrument panel of the VAZ 2113 are completely similar to the fourteenth model) there is a dial gauge for the current amount of fuel in the gas tank.

The sensor scale is divided into three marks: 1 – full tank, ½ – tank half full, 0 – empty tank.

Next to the sensor there is a color indicator - a light bulb that lights up orange when the fuel level is close to a critical minimum. When the light comes on, you need to refuel the car within 20-30 kilometers.

Cooling system fluid temperature sensor

The coolant temperature sensor is divided into gradations of 20 units. The minimum temperature is 50, the maximum is 130 degrees. The critical temperature zone starts at 105 degrees and is marked with red shading.

If the coolant of the fourteenth boils, then you must immediately stop the car and turn off the engine, since driving in this mode is fraught with serious troubles, even complete engine failure.

If the temperature sensor on the VAZ 2114 dashboard does not work, you need to check the wiring through which the sensor is connected to the coolant container. It is also possible that the sensor contacts may oxidize; they must either be wiped with a solvent or the sensor replaced with a new one.

What is the central locking on the VAZ 2110?

The purpose of this type of device is to centrally control the automatic mechanism for opening and closing all doors in the car at once. This is especially convenient for working in conjunction with an alarm system and when operating a car in general. However, the reliability of the operation of the central locking system should definitely be checked every time by moving the handles of all four doors before going about your business for a long time, since the actuator can often fail and one of the doors may remain unlocked.

Structurally, the VAZ 2110 central lock consists of the following elements:

electronic transistor control unit;
gearmotor actuators, also known as activators (one for each door);
a limit switch that determines the current state of the door (open or closed);
electrical wiring and other installation elements.

Central locking diagram for VAZ 2110

Why the central locking on the VAZ 2110 does not work correctly

The problem of improper operation of the actuator is not at all uncommon for cars in the domestic automobile industry. Despite the fact that there are a number of reasons for the failure of mechanism parts, the principle of operation of the automatic door closing system is quite simple, and the malfunctions are very typical in their entirety. This means that any motorist can deal with them.

You don’t have to grab your head and run to the workshop in search of a qualified specialist. Thanks to the diagnostic recommendations below, you yourself are very likely to become one. If, for some reason, you don’t want to get your hands dirty, at least no one else will dare to mess with you. And this, you see, also costs a lot.

Problems in the operation of the activator electric drive

The central locking actuator is quite fragile and does not tolerate overload. The activator body, made of plastic, can easily melt if the frequency of door closing is excessively high. The duration of the control pulse also plays an equally important role. Try to always remember about the extreme fragility of the activator and not to load it during operation.

It is easy to guess that the activator is located in each individual door of the car. If the body of one of them melts due to overheating of the electric drive commutator, this becomes the cause of many problems:

the activator on individual doors stops functioning;
Constant overloads in a jammed electric drive cause the fuse to fail.

The actuator mechanism is entirely made of plastic. Gears can easily wear out and break during operation, or melt when the commutator overheats. As a result, when the central locking operates, characteristic creaking sounds are heard - a sure sign of imminent failure of the activators. Likewise, if the gearbox of the mechanism is humming, but the doors do not open or close.

Problem in the operation of the central locking electrical circuit on VAZ cars

The first possible problem follows smoothly from those mentioned in the previous section. Overload in the operation of activators leads to an increase in the operating current in the supply circuit above the rated value. As a result, the fuse blows and the central locking of the VAZ 2110 simply “dies”.

It is by checking the fuse that the diagnosis of central locking malfunctions begins. By the way, it is located in a very specific place and it is not easy to find it right away even if you know where to look. In order to get to it, you will need to fold back the central panel with the fuses and dig into the entire wiring harness in the niche that opens behind it. The “comrade” you need is packaged in a special plastic cup and connected to the pink wire.

Central locking unit VAZ 2110

Another very common and obvious problem is the central locking connector. It is located in the most unfavorable place for this in the interior body, under the foot mat. A large amount of moisture and dirt inevitably gets there. Electrical contacts are intensively oxidized. As a result, the power supply circuit involuntarily breaks at the point where the plug connector is connected.

Problem with the operation of the VAZ-2110 central locking control unit

Electronics, of course, are reliable things. Modern control modules for the central locking VAZ 2110 are assembled using a transistor control circuit. This eliminates their mechanical wear. The shelf life of key components is measured in tens of years. The control unit is located under the plastic dashboard cover on the right side of the driver's seat.

However, power transistors can easily fail when the activators are overloaded and the collector is short-circuited. It may even happen that the signal from the control unit will constantly be sent to the lock drive if the transistor is broken. Otherwise, it will simply not turn on.

Checking the control unit is extremely simple. The voltage from the negative terminal of the battery, or directly from the pink wire supplying the control unit, is supplied to the contacts of the gearmotor (activator) in series to the red and yellow conductors. All of the above contacts can be found directly on the eight-pin connector of the control unit.

Thanks for subscribing!

Also, the control unit may issue erroneous control commands due to incorrect operation of the limit sensor. Being a mechanical device, the main door switch can simply wear out. As a result, the control unit simply will not be able to function correctly, since it will not know in what position the car doors are currently located, whether the driver's door lock is closed or open.

Repairing broken wires

As a rule, most often the wires break off or break in the corrugation of the door. This is due to the fact that the door is constantly opening or closing, and the wire insulation is quite thin. To eliminate the problem of broken wires from the rubber corrugation of the door, you need to slowly pull out one wire at a time that approaches or departs from the central locking unit for power or control. A broken wire can easily be pulled out of the total mass. You can connect the break using a simple connection using male-female terminals. If the break occurs in another place, it is necessary to test all wiring with a multimeter. When checking, it is worth remembering that voltage will be present on one wire only at the moment of opening, and on the other - when closing the central lock.

How well do central locking and alarm systems work together in VAZ-2110 cars?

As you know, a modern alarm system involves autonomous control of all opening parts of the car. For this reason, it is possible to connect the VAZ 2110 central locking system to the alarm system. The connection diagram for the signaling device is included in the operating instructions for the device. The central locking control circuit also seems to have an additional unused connector for this purpose.

However, in reality it is not so simple. Control signals from the alarm system to the central locking system will conflict with the information received from the limit switch installed in the driver's door. For this reason, the standard central locking control circuit with which VAZ 2110 cars are supplied from the factory should be slightly altered.

The essence of the modification is extremely simple. According to the circuit diagram, the limit switch is connected to the eight-pin connector of the central locking control unit via two wires: brown and white. These wires from the unit should be disconnected.

Now the limit switch will be connected to the alarm control circuit, and the alarm will set control signals to the electronic unit of the central locking. Perhaps the diagram described “on fingers” may seem somewhat incomprehensible to you. But it will be very easy to understand the above by studying the diagram proposed below.

Central lock VAZ 2110

To better understand the idea of connecting an alarm, it is still worth studying the instructions included with it. Thanks to this, you will have a clear idea of how to implement this idea in practice. But the essence of the connection will remain the same. The work requires minimal effort and is generally very simple.

Selecting a security alarm for installation on a domestic car

The function of remotely closing and unlocking all car doors is mandatory for all types of modern anti-theft alarms. It is impossible to install an alarm without a central lock, so car owners are forced to install a central lock before purchasing a security system.

The trade offers motorists hundreds of models of anti-theft alarms in a wide price and functional range.

When choosing a car alarm for installation on domestic cars, the main selection criteria for car owners are:

Affordable security system price. Experienced car enthusiasts do not buy the cheapest anti-theft alarms, doubting their durability and quality of work. Most Russian drivers prefer to buy car alarms from the middle price range.
System functionality. Ordinary owners of VAZ models consider the car alarm to include a remote key fob, two or three sensors, a siren, and connection cables as a sufficient set of options.
Possibility of self-installation. To implement this requirement at the purchase stage, you need to be interested in the complexity of the electronic control unit for the security system, detailed diagrams and instructions for connecting the anti-theft alarm. When installing it yourself, minimal disruption to the standard electrical wiring is desirable; it is not recommended to interfere with the operation of existing mechanisms.

Owners of VAZ-made models do not need to worry about the difficulties of flashing factory protections or bypassing standard immobilizers. However, experts do not recommend that novice car tuning enthusiasts begin work by independently installing security systems equipped with:

remote engine start (remote engine start based on temperature, timer);
coded dialogue communication system, GSM modules;
numerous additional options (starting from a smartphone, turning on heaters, air conditioners).

If you want to install a full set of security options on a VAZ model, you will have to contact a specialized service, where they can install additional equipment.
