Connection diagram for the trunk release button VAZ 2110

Car enthusiasts are often interested in why the trunk does not open with a button on the VAZ 2110 and 2112. For modern cars, opening the trunk with a button is quite common. Even on models that were not originally equipped with such an option, it can be found. Usually, the button is installed simultaneously with the installation of the central locking or alarm system.

In the second case, the trunk lock is integrated with the security system. Failure of the trunk lock is quite an unpleasant phenomenon. For example, if necessary, you will not be able to get a spare tire. Therefore, it is important to fix the problem as quickly as possible.

Possible causes of the problem

Why doesn't the trunk open from the button on the VAZ 2110 and 2112? Let's start with the fact that the lock drive is electric, so the problem often turns out to be related to this particular system of the car. We list the main causes of malfunctions:

• Motor malfunction;
• Broken wiring;
• Problem with key fob or button;
• Weak battery.

There are several reasons, each of them has its own symptoms and characteristics. Below we will look at the main nuances of diagnosing a lock.

What do you need for work?

A similar connection diagram for the trunk button attracts many.

To realize your idea, you need to prepare materials and tools.

• electric drive (activator) of the luggage compartment lock;
• universal 4-pin relay;
• fuse blocks;
• fuse;
• wires;
• female type terminals;
• trunk opening buttons;
• heat shrink tube;
• electrical tape;
• plastic clamps.

The block is placed for safety reasons. Mounted on the positive wire. The fuse can be taken as standard, 10 Ampere. Do not need anymore.

Determine the length of the wiring individually. But practice shows that 5-6 meters is enough with a margin.

Take the opening button from ten. It is considered the most reliable and also affordable. If you are tuning a domestic car, then it will definitely fit.

At any car market it will not be difficult to buy the entire set. It will cost 600-800 rubles. Maximum 1000 rubles.

Motor malfunction

Let's say the key fob or button works as usual, but the trunk does not open. Most likely the problem is in the electric lock motor. First you need to open the cover to get to the motor. To do this, you will have to remove the back of the rear sofa and, reaching for the lever, open the trunk from the passenger compartment. You can do without this if you did not remove the cylinder when installing the electric lock. In this case, you can get by with a simple key.

We remove the motor. It should be checked. To do this, we apply a voltage of 12 V to it. A working motor will spin, if not, then it is better to buy a new one. If you wish, you can try to fix it. There are only 2 reasons for the failure:

• Winding short circuit;
• Burnt out resistance.

A shorted winding cannot be restored. But the resistance can be easily replaced. To do this, you need to disassemble the motor and replace the burnt out resistance. It is best to use a copper plate.

Broken wiring

This is perhaps the most common malfunction on self-installed electric locks. The reason is an unsuccessfully selected place for pulling the wires. As a result, they are damaged, which leads to a short circuit or complete breakage.

Diagnostics can be divided into 2 parts:

• Checking resistance. All sections of the chain are checked for damage. If this indicator is close to infinity, then somewhere the wire has broken off. You can also check this by measuring the voltage;
• Carefully inspect the wires for damage to the insulation. This usually leads to short circuits and current leakage to the housing, which makes the lock impossible to operate.

To check, you will need a multimeter or a tester made from a regular 12 V light bulb. Pay attention to the contacts. Often they oxidize, which does not allow current to flow normally. It is recommended to regularly check the status of the contacts. Be sure to clean them twice a year and lubricate them with a special compound. In many cases, it is poor contact that causes the lock to fail.

Preparation for installation

We purchase a lock kit. There are a lot of manufacturers of auto parts on the market now, but there are no special differences between the sets. It is important that the device has a warranty card and instructions for use and connection. Also in the box you will find:

Additionally, you need to stock up on a set of standard tools: pliers, screwdriver, screwdrivers, multimeter, drill with carbide drill bit. In addition to the standard accessories, immediately buy additional wires; it is quite possible that the length of those you find in the box will not be enough for you. Black heat-resistant insulating tape, corrugated tubes, and clips for fastening the trim will also be useful, since very often the trim of car elements is attached to disposable ones.

Important! Be sure to check that the warranty card for the purchased device is available and filled out correctly. Regardless of who performed the installation, you or the service, you have the right to free repairs within a year.

Stories from our readers

“Fucking basin. "

Hi all! My name is Mikhail, now I’ll tell you a story about how I managed to exchange my two-wheeler for a 2010 Camry. It all started with the fact that I began to be wildly irritated by the breakdowns of the two-wheeler, it seemed like nothing serious was broken, but damn it, there were so many little things that really started to irritate me. This is where the idea arose that it was time to change the car to a foreign car. The choice fell on the melting Camry of the tenth years.

Yes, I had matured morally, but financially I just couldn’t handle it. I’ll say right away that I am against loans and taking a car, especially not a new one, on credit is unreasonable. My salary is 24k a month, so collecting 600-700 thousand is almost impossible for me. I started looking for different ways to make money on the Internet. You can’t imagine how many scams there are, what I haven’t tried: sports betting, network marketing, and even the volcano casino, where I successfully lost about 10 thousand ((The only direction in which it seemed to me that I could make money was currency trading on the stock exchange, they call it Forex. But when I started delving into it, I realized that it was very difficult for me. I continued to dig further and came across binary options. The essence is the same as in Forex, but it’s much easier to understand. I started reading forums, studying trading strategies. I tried it on a demo account, then opened a real account. To be honest, I didn’t manage to start earning money right away, until I understood all the mechanics of options, I lost about 3,000 rubles, but as it turned out, it was a precious experience. Now I earn 5-7 thousand rubles a day. I managed to get the car buy after half a year, but in my opinion this is a good result, and it’s not about the car, my life has changed, I naturally quit my job, I have more free time for myself and my family. You’ll laugh, but I work directly on the phone)) If If you want to change your life like me, then here’s what I advise you to do right now: 1. Register on the site 2. Practice on a Demo account (it’s free). 3. As soon as you get something on the Demo account, top up your REAL ACCOUNT and go to REAL MONEY!

How to open a VAZ-2110 without a key

The opinion of most experts agrees that the VAZ-2110 does not need to be locked. However, if this happens, then it is recommended to use wire (can be replaced with a rope with a loop), having previously made a hook at its tip, and scissors. The method described below will be extremely useful and interesting for those car owners who often forget their keys. So, to open a VAZ-2110 car, you need to perform the following manipulations:

• remove the elastic band with gentle movements;
• use wire to penetrate the small space between the glass and the top of the door to the very end;
• lingering in this position, you must slowly and very carefully try to pick up the door latch;
• if everything is done correctly, the door will open.

A completely logical question next would be: how to start a VAZ-2110 without a key? To carry out this action, it is necessary to perform the following manipulations:

1. Carefully pull out the size button and plug it into the first three connectors, leaving one free - this should not be alarming.
2. If the above action is performed correctly, the fuel pump will begin to function and the ignition will turn on.
3. The next step is to open the hood.
4. Now the starter is carefully shortened using scissors.
5. If done correctly, the car should start.

Finally, it is important to activate all immobilizers. We should also not forget that it is strictly not recommended for owners to leave the car in this condition unattended.

Why? Everything is very simple - the work of opening and starting a VAZ-2110 car

It is not particularly difficult and almost anyone can cope with it. Most experts insist that owners of Russian cars install high-quality alarm systems. To some extent, this can protect the owner of a domestic car from possible theft.

Self-installation and connection

You will need : an actuator, 4 meters of wire, a fuse, a VAZ 2110 trunk release button, a 4-pin relay.

If you install it yourself, you can follow the example of the manufacturer by making a plate for mounting the actuator according to the following diagram:

Another method of installing the electric drive does not involve the use of a special fastening, but it will eliminate the possibility of opening the trunk from the outside.

1. Loosen the lock drive rod screw.
2. Remove the lock drive rod.
3. Having attached the electric drive to the lock, mark the holes for its fastening on the trunk lid amplifier.
4. Drill two holes with a diameter of 5 mm.

1. Drill a hole in the lock drive boss to a diameter of 3 mm.
2. Bend the rod as shown in the photo.
3. Secure the electric drive with a bracket threaded from the inside into the cover reinforcement and with nuts screwed onto the threaded ends of the bracket. We connect the electric drive to the lock with a rod.
4. We install the button in its normal place.

We stretch the wires under the headliner or under the plastic sills on the left side of the body. Connection diagram for the electric trunk drive using a relay:

This method of installing an electric trunk lock drive is also suitable not only for modern Lada cars (for example, Lada Granta, Lada Kalina, Lada Priora, etc.), and for foreign-made cars.

Let us remind you that there is another interesting way to place the button - instead of the trunk lock.

Hi all. Well, we finally got around to the trunk to open the trunk with a button. I’ve just been thinking about implementing this idea for a long time, but somehow there wasn’t enough time. Everything is done, it just takes a little time. We will do this using the example of a VAZ 2107 car. So, what do we need:

-Activator -Fuse block (I will drive the plus from the battery) -Fuse -Wire, I took it with a reserve of 7m, -Button for opening the trunk of a VAZ 2110, -Terminals “Mother” -5-pin relay (you can have 4, I’ll explain later why I took exactly 5) -Well, you’ll also need electrical tape or heat-shrink tubing

I’ll explain why I took a 5-pin relay, it’s simple, because I opened the alarm book, namely the connection diagram, and it described how to connect a relay of this type, so I decided to take it so as not to look for connection diagrams on the Internet.

The principle of opening the trunk: electric drive circuit

Before understanding the functioning of individual components of the entire electric drive system, it is important to give a clear understanding of what its main mechanism is. Such a mechanism is often mistakenly considered to be an electric drive itself, but it is more accurate to talk about an electric drive not as a “piece” device for a car, but as a single structure, electrical equipment. The role of the central device in such a structure - specifically when opening/closing the trunk of a car - is performed by a specific rod.

Telescopic rod (rod). 3D axonometric projection

The rod is distinguished by its mobility, variability in dimensions and, in general, seems to be universal in use: it is called “telescopic” both in large convection devices and in smaller gas units. The operation of an automobile electric drive is significantly affected by the following parts of the rod (shown in Figure 1):

• spring;
• spring brake;
• two-stage gearbox;
• moving valve nut;
• lead screw;
• current transducer (measuring);
• electric engine.

What does the column of a telescopic rod for an electric drive of a car consist of?
Detailed drawing What is the uniform operating principle of the system:

1. The button located in the passenger compartment on the door (or to the left of the steering wheel - depending on the model), when pressed, transmits a signal to the control unit (relay). The latter is mounted under the dashboard; All the necessary contacts for connecting the remaining parts come from there.
2. Everything that is located in the trunk, outside the cabin - and this is the fuse, the alarm unit and the rod itself - receives the signal from the control unit (relay). The final command falls on the bar. When it is received, the engine built into the bar is activated and the trunk is raised/lowered.

Additional modernization of locks

If you dream of your car doors opening and closing as smoothly as in foreign cars, try installing silent locks. Such a device can be installed on any model of Zhiguli. For representatives of the retro era, such modernization is also possible, but the locks themselves will have to be filed a little. By the way, you can also put it on the trunk. In general, there is no limit to perfection.

And the installation is, in truth, very simple and transparent. It is enough to dismantle the old locks, try not to drop the necessary elements inside the door, or remove the trim in advance. And then install new analogues on two bolts. There are situations when, after installation, the door does not close tightly or warps slightly, causing cracks to form. Solving the problem is also very simple by adjusting the location of the device. In general, initially try to secure it exactly where the old one was.

Who can you trust to re-equip closing devices?

This modernization can be offered to “tuners” who will save you from unnecessary locks and keyholes and handles located on the outside of the luggage compartment lid and car doors. In order to control the trunk locking device, you will need an electrical contact device.

This system will work as follows: by pressing a button, which is located in any convenient place for the driver, an additional contact system is activated, which starts the main relay, after which the core is retracted and the trunk lock latch is opened. In this case, we cannot do without auxiliary parts and fasteners, for this reason we will have to make a fastening device for the roller. This wheel, with the help of a screw, is easily attached to a bracket, which is held on the body by a special screw.

Review of Manufacturer Prices

*prices are current as of 10/09/18.

The opinions of the service station masters agreed on the choice of manufacturer - there is not much difference. When purchasing original products, the service life of the equipment exceeds 5 years. Installation in “makeshift” conditions and poor-quality manufacturing only shorten the period of use of the equipment. Often the owner is to blame for the breakdown, violating the vehicle maintenance regulations.
