Where is the fuse for the VAZ-2110 radio?

Any car cigarette lighter, including the VAZ-2110, was initially designed only for use for its intended purpose. However, over time, “necessary” car gadgets began to appear that needed to be connected somewhere. Since the factory did not provide for the installation of a 12-volt outlet in the car, the cigarette lighter is the power source for vacuum cleaners, refrigerators, televisions, video recorders, compressors and phone chargers. This does not benefit him and quite often he breaks down at best.

At worst, a connected gadget left unattended can lead to a fire.

Where is the fuse for the VAZ-2110 radio?

Fuse links are installed in the wiring of passenger cars to protect the equipment from short circuits. The fuse for the VAZ-2110 radio ensures normal operation of the head unit and related components. When installing an additional active-type subwoofer or amplifier, it is recommended to connect separate protective elements in the power supply circuits of the devices.

Understanding nutrition

Car enthusiasts often write that the radio in their car does not turn on or, conversely, does not turn off. There are problems with power supply chains here. The reason is an incorrect connection, power surges in the network.

The radio may indeed not turn on or turn on, but some of its functionality will be unavailable. For example, there may be no display backlight, operation in player mode, or no sound.

In these cases, it is usually recommended to carefully check the functionality of the protective fuse, as well as the protective diode. It would also be a good idea to inspect the printed circuit boards. There you need to look for “burnt” tracks or swollen capacitors and damaged microcircuits.

As for the power supply issue, if the connection is incorrect, the poles of the wires may be accidentally reversed. Also, the contacts may simply wear out or short to the housing.

If you replace that fuse and it blows again, then things aren't that simple. You will have to use a soldering iron or take the device to a service center if you do not have basic knowledge of electronics.

So, first the “music box” needs to be disassembled. This must be done from the board side. So, you need to inspect everything carefully. Some car enthusiasts connect the device directly without a fuse. This will sooner or later lead to the radio in the car burning out.

If burnt tracks on the board are visible, they can be restored. Swollen capacitors can be replaced. And then again enjoy music in the interior of your car.

Functions

A blade-type fuse is a wire designed to carry a certain amount of current. If the parameter is exceeded, part of the element is heated and melted, which allows the power circuit to be broken.

To install the part in the mounting block, flat rectangular legs are used, which are clamped with spring contacts. Metal parts are placed in a plastic case; the color of the material depends on the product rating. The body is transparent, which allows you to visually assess the condition of the fuse thread.

Where is

The fuses located in the instrument panel to the left of the steering column casing are responsible for protecting the power circuits on VAZ-2110 cars. The top of the unit is closed with a decorative cover, which is secured with a spring clip. To access the fusible links and relays, you need to press the button located under the rotary control for the headlight range control. The decorative casing folds down along with the mounting plate and the protective and distribution devices. On VAZ-2112 and 2111 cars, blocks are used that differ in the number and location of the relays.

Also inside the mounting block are special plastic tweezers and spare inserts. To replace the fuse, the part should be grabbed tightly with tweezers and then carefully pulled out of the socket. The new part must have an identical value; the use of homemade inserts made of wire or foil is strictly prohibited.

The use of fuses designed for high current strength is not allowed, as this may cause the wiring to heat up and the vehicle to catch fire.

Since the cars of the “tenth” family were not equipped with a standard head unit, the installation of radio tape recorders was carried out at dealership centers or by the owners themselves. Since the head acoustic device is a consumer of electric current up to 10-15 A, it is switched through the most powerful fuse. In most cases, this was done using a fuse link designed to protect the cigarette lighter circuit and heater controller. The device has a rating of 25 A, located in the bottom row in the third position from the right.

This switching scheme speeds up installation, but is not correct, since there is a risk of overloading the radio or burning out the insert due to the simultaneously operating head unit and cigarette lighter. It is recommended to connect the radio directly to the battery; a 10-15 A fuse is located inside the power cable.

To protect the battery from discharge, the circuit passes through the ignition switch; a cord with red insulation is used for switching.

When the engine is turned off, the radio does not work, but voltage is supplied (through a yellow insulated cable) to save the settings.

The head unit contains a blade-type fuse rated at 5-15 A (depending on the equipment modification). The element is placed either next to the ISO standard connection block, or inside the wiring harness that comes with the radio. To replace an element, you need a player from a standard socket; for this, special hooks are used that press out the spring clamps.

After installing a new element, it is recommended to check the functionality of all devices involved in the circuit section. If the fuse blows again, the cause of the malfunction is a short circuit in the electrical wiring or inside the head unit. A tester is used to check the condition of the wires; it is recommended to send the radio to a service center for diagnostics and repair.

Causes

This disease can be cured. This is done in the same way as in the case of home appliances. It is necessary to disassemble the drive and then clean the lens. In most cases, this is enough to listen to your favorite music on the road again.

• Both plastic and metal tend to “get tired”. Thus, all mechanical parts made of these materials are sooner or later subject to wear.

• Another reason for car radio failure is dirt. Over time, dust and dirt accumulate between the parts due to the operation of the car radio in extremely harsh conditions. In this case, failure of the optical part or various mechanical parts becomes common.

• Another common cause is mechanical failure, related in one way or another to the power circuit. Incorrect connection of the car radio or sudden surges in voltage in the on-board network are the root cause of such breakdowns.

Car radio fault codes

In some cases, it may be enough to simply completely disassemble the CD drive, then carefully clean the laser reading lens itself. The car radio then starts working as if nothing had happened. This ease of repair of car radios can be explained by the fact that during operation, dust settles on the lens, which ultimately affects focusing.

In cars, a fusible type of fuses is installed. That is, devices that burn out as a result of short circuits and similar accidents. How to interrupt a contact connection on a certain section of electrical wiring. In terms of the power they can withstand emergency loads, safety devices differ in their rated voltage, as indicated by their markings and a duplicate inscription near the connector socket intended for its installation.

In Soviet-made cars, cylindrical fuses were installed, which were very unreliable in operation and quite unsafe due to their technical design. Today, in all VAZ products without exception (VAZ 2110, VAZ 2114, Priora, Kalina, etc.), as well as in foreign-made cars (Ford, Audi, etc.), blade fuses are used. More advanced in their design and aesthetics, devoid of the disadvantages inherent in their predecessors, cylindrical fuses.

The relationship between a car lighter and a radio in VAZ cars

A common problem for all VAZ car models (2114,2115, 2109, 2110 , 21099), this is the same voltage supply circuit to the car player, with output to one common fuse, which is additionally responsible for the power supply:

Thus, a failure as a result of a break, short circuit, etc., in the electrical circuit of any device leads to the shutdown of the rest.

Since the tape recorder is equipped with an additional safety device, coming after the main one, after checking them and replacing them, if necessary, the operation of the head unit, like all the above-mentioned equipment, is restored. If only the cigarette lighter (without the player) resumes operation, the cause of the malfunction should be sought in the car radio itself (which is the topic of a separate article).

Fuse layout diagram for VAZ 2110, 2111, 2112

Many owners of VAZ cars are familiar with the situation when the cigarette lighter suddenly stops working, the turn signal does not respond to being turned on, and the windshield wiper blades stop cleaning the glass. Many people then immediately run to the store for a new part, making an incorrect diagnosis. Most likely the problem is a blown fuse. These parts protect the wiring of our car from burning out.

Let's take a closer look at the fuse diagram for the VAZ 2110, 2111, 2112. The first VAZ fuse block is located in a special niche, to the left of the steering wheel.

How are the blocks separated in the machine?

The main type of block is placed in the most convenient place for the driver. In this version of the VAZ it is located on the left side of the body directly at the steering wheel. Easy access to the unit is provided using a built-in button located next to the car's headlight control.

2 backup units with relays are located separately in the right and central parts of the console just behind the dashboard. One of the fuses shown below in the diagram will be located at a distance from the rest of the list - it can be found in a special compartment behind the main fuse block, next to the mounting block. To timely repair electrical equipment on a VAZ-2110, you need to learn how to quickly determine the location of a blown fuse, and also know which elements of the car its failure will affect.

Advice: very often one burnt valve can lead to replacing the vacuum booster on a VAZ-2110. That is why it is important to check not only the general condition of the fuse, but also the parts that interact with it, for example, the injector.

Where is the fuse for the radio?

The fuse responsible for the radio is located in the power circuit. If the head unit is connected through the cigarette lighter cables, then the safety insert of the blade type or cylindrical configuration is located in the installation box inside the instrument panel. The distribution panel is located on the side of the steering column, under the hinged plug. On some machines, the inserts are mounted on a panel covered by the panel's end cover. Analysis of the electrical diagram pasted on the cover will allow you to find the desired insert.

The fuse for the radio is placed in the power cable, which comes from the battery terminal. The cassette-type insert has a rating of up to 50 A (depending on the power of the connected acoustic components), and is located at a distance of 400-500 mm from the power source. The upper part of the assembly is made of transparent plastic, which allows you to visually check the condition of the fusible element.

The design of the radio has an individual protective element responsible for protecting the electronics. A knife-type insert with a rating of 5-15 A (depending on the power of the amplifier and the total power consumption of the head unit) is inserted into the socket near the ISO switching connector. A similar element is used in standard radios.

Why does a fuse blow?

The purpose of any electrical fuse is to protect the connected consumer from current loads exceeding the permissible (established by the manufacturer) values. A car fuse is a small plastic part, inside of which there is a wire with two terminals designed to connect the fuse to a specific section of the electrical circuit. The principle of operation of the fuse responsible for the cigarette lighter is no different from all its other brothers: if the current strength exceeds the permissible values ​​(constant for a PP of a particular rating), it begins to heat up to such an extent that its middle section melts. The chain breaks, and the consumer remains unharmed, since the fuse took the entire blow, sacrificing his life.

This approach is more than justified - the cost of the fuse is cheap, it can be replaced in a matter of seconds.

Since the on-board electrical network of a modern vehicle includes more than a dozen consumers, the number of fuses is also large, and some of them protect not one, but several electrical devices. They all differ in denomination, designed for a certain value. In particular, the cigarette lighter fuse rating in most cases is 15A.

In addition to the current value, PPs differ in size and color. Coloring them should, in theory, make it easier for motorists to navigate, but few of them can say with certainty what the fuse is intended for, judging only by its appearance. Rather, this “feature” turned out to be useful for auto electricians, but not for mere mortals.

What makes the situation even more confusing is the use of different automakers’ own color schemes, which do not always coincide.

So if, for example, your cigarette lighter fuse has blown, before replacing it, it is better to study the user manual in order to avoid making a mistake that could be fatal.

Here is the marking of the fuses located in the block depending on their standard size (in ascending order):

• Mini (the smallest),
• Medium (medium-sized),
• Maxi (large),
• JCase (cartridge type),
• PAL (also in a cartridge type shell),

Note that it will not be possible to replace a blown cigarette lighter fuse with a PCB of a different type with the same rating, since it will not have the same shape of the socket - this must be taken into account when going to a car shop. Having told the seller how many amperes the cigarette lighter fuse of your car is, you will receive a perplexed face in response - the value alone is not enough.

The burnout of an automobile PP, as already noted, is caused by only one reason - an abrupt excess of the rated current value. But if we talk about why such situations arise, the reasons may be different. Typically this is the use of devices whose electrical parameters do not correspond to the characteristics of the on-board network or the fuse rating. As for the cigarette lighter specifically, a factor such as the consumer’s continuous operation time comes into play: for a cigarette lighter it is about 10 seconds, and if you connect a car vacuum cleaner, it can work hard for an hour. However, the cigarette lighter itself can be activated almost continuously, and this can also be an unbearable load on the fuse.

And since most new electrical appliances are connected specifically to the cigarette lighter socket, you need to clearly understand what load this device is designed for.

But even in cases where the electrical characteristics of the connected device fully correspond to the parameters of the on-board electrical network, this does not mean that the risk of failure of the PP is zero. Voltage surges have been, are and will be, and it is impossible to predict them, since their activator can even be a purely external factor - for example, driving near a powerful source of electromagnetic waves. However, the most common reason for a cigarette lighter fuse to blow is the connection of heating devices - an electric kettle or a boiler, which require high power for their operation, and for a long period of time. So if you are a big fan of hot drinks, please stock up on a set of PP - you will definitely need them.

But the use of less load-demanding, but low-quality electronic devices (for example, DVRs assembled from unknown places) can also cause fuse failure.

How to find and replace a fuse on a radio

In cars, a fusible type of fuses is installed. That is, devices that burn out as a result of short circuits and similar accidents. How to interrupt a contact connection on a certain section of electrical wiring.

Which fuse is responsible for the cigarette lighter of the VAZ 2110

If the cigarette lighter of a VAZ 2110 car malfunctions, you need to open the main panel, which is located in the lower left part of the dashboard. There is a VAZ 2110 cigarette lighter fuse. It is marked F 18 and can withstand loads of up to 25A.

To replace it, you should use special tweezers. Under no circumstances should you remove the element with your fingers - this may damage the mounting sockets.

Where is the fuse for the radio?

The fuse responsible for the radio is located in the power circuit. If the head unit is connected through the cigarette lighter cables, then the safety insert of the blade type or cylindrical configuration is located in the installation box inside the instrument panel. The distribution panel is located on the side of the steering column, under the hinged plug. On some machines, the inserts are mounted on a panel covered by the panel's end cover. Analysis of the electrical diagram pasted on the cover will allow you to find the desired insert.

The fuse for the radio is placed in the power cable, which comes from the battery terminal. The cassette-type insert has a rating of up to 50 A (depending on the power of the connected acoustic components), and is located at a distance of 400-500 mm from the power source.

Additional fuses: 1 – ignition module, controller; 2 – canister purge valve, vehicle speed sensor, oxygen (heating) sensor, air flow sensor; 3 – fuel pump relay, fuel pump, injectors.

Additional relays: 4 – electric fan relay; 5 – electric fuel pump relay; 6 – main relay (ignition relay).

There is a fog lamp fuse installed in the niche of the instrument panel behind the mounting block:

Functions

The fuse of the radio, located in the power circuit, is designed to protect the electronic components of the equipment from the consequences of short circuits. The device is a thin thread of low-melting metal, designed to carry a certain current value. As the value increases, the element heats up and subsequently melts. The process takes place in a short time, which allows you to maintain the player’s electronics and the insulation of power cables in good condition.

The thread is soldered to the legs, all elements are housed in a transparent plastic case. The color of the plastic allows you to determine the rating of the fuse link; the digital value is applied to the end part with white or black paint. A fuse of this type is called a blade fuse and is installed in the mounting block in spring contacts that protect the product from falling out.

Trouble-shooting

Having established the reason why the VAZ cigarette lighter and radio are not working, we correct the detected breakdown. The list is given in accordance with the listed faults.

1. We remove the fuse box (the hatch on the left side of the steering column of the car). We remove the device marked F4 (20 ampere fuse), test it for serviceability with a simple screwdriver probe, if this moment is not visually determined. And we replace it with a new one from the mandatory kit for such cases.
2. Check the conductivity of the contacts with a probe. If they are loose, tighten them.
3. Strip or resolder the contacts, depending on the situation.

Paradoxically, a burnt-out light bulb breaks the contact circuit (a kind of fuse). Replace it with a working one of the same power.

A short circuit most often occurs due to a loose cigarette lighter socket and a malfunction of its heating coil. If you have the opportunity, then replace them with new ones or restore them to proper condition.

What to do if the safety device malfunctions?

The answer is also not difficult. Replace the burnt device with a new one that fully complies with the technical parameters of the previous one. It is not expensive and is sold in all auto parts stores. As a little advice. Have a spare fuse or even several. Since they fail quite often, especially in winter and summer. And also when repairing a car. This is explained by the increased load on the electrical system when the air conditioning and interior and seat heaters are running. Negligence when disconnecting the battery (de-energizing the network) during minor repairs, etc.

Expert advice

Professional automotive electrical repair technicians complain that even when carrying out repairs that are so insignificant in scope and complexity on their own. Some car owners manage to violate basic rules, thereby significantly aggravating the problem and transferring it to another, more complex (and expensive) repair category.

What is a cigarette lighter and where is it located?

To put it simply, the cigarette lighter socket is the simplest socket that has voltage. On such brands of cars as VAZ 2112, VAZ 2115, VAZ 2110, it is no more than 13 volts. Basically there is one nest. But on more modern and foreign-made Toyota Corolla and Renault Logan cars, their number can increase to two or three.

The design of this part is quite simple, so there are no difficulties during its operation.

Replace fuse

Connecting any electrical device is simple and without additional effort. The main thing is that it has the appropriate connector. This process is often compared to plugging a plug into an outlet.

But, like any other device, the cigarette lighter has its own characteristics. It is very important to take them into account when using it. Otherwise, you may encounter problems with it breaking. This is typical not only for domestic cars VAZ 2112, VAZ 2115, VAZ 2110, but also for many other newer ones.

Any breakdown in a car causes a lot of inconvenience to its owner. Even if at first glance it is not significant, and does not affect his overall work. But it may result in a malfunction of another device. Thus, for VAZ 2112, VAZ 2115, VAZ 2110 cars, the cigarette lighter and radio tape recorder have stopped working. They are interconnected, and this is more serious and it will not be possible to postpone solving the problem.

How to remove and replace the relay and fuse mounting block on a Lada Priora

But there are often cases when it is simply not possible to replace one relay and fuse. In this case, you have to replace the entire mounting block. For this:

1. Disconnect the minus terminal from the battery
2. Removing the cover of the mounting block
3. We unscrew the screw securing the mounting block to the instrument panel
4. We remove the mounting block from the instrument panel, disengaging it from the mounting hooks.
5. Remove all relays and fuses from the mounting block
6. We press out the clamps of the electrical wiring terminals
7. We remove the terminals with wires from the mounting block and remove the mounting block from the car

If there is no sound

Modern musical and automotive technology has one weak point. This is a UMZCH microcircuit. This is an amplifier. It often fails due to incorrect connection of the speakers.

If you decide to install the device in a car, you should connect the power last, after checking all other connections. This microcircuit also crashes if there is a power surge in the on-board network.

The power supply of this microcircuit is not stabilized by anything at all. It can fluctuate within significant limits. Some microcircuits want more voltage than the network can supply. Here you only need to replace the microcircuit or go to a service center.

Also, sometimes the radio does not play in the car due to wiring problems. In this case, you need to check the AUDIO fuse. In most radios it can be found in the mounting block. If the fuse is intact, then you need to start the car, and then use a tester to check whether voltage is supplied to it.

If there is voltage, then you need to examine the car electrical system and the correct connection.

Location

Since AvtoVAZ engineers tried to do everything so that car owners would not have problems replacing relays and fuses, it would be stupid to come up with a clever arrangement. Therefore, finding them is not difficult.

• The main unit is located to the left of the steering wheel;
• You will find the first additional block in the dashboard inside the niche, directly behind the main mounting block;
• The second additional block is located in the same place, only on the opposite side.

We will get acquainted with each block separately so that you do not have any confusion when searching for one or another fuse.

On injection engines with 16 and 8 valves, the location of the MB is identical, so the instructions are equally relevant for owners of both versions of the dozen.

Main MB

Relays and fuses are located here. Let's look at their descriptions in more detail and separately.

Found the main MB

Let's start with the relay.

Fuse diagram

Next comes the fuses. They are located in the same place, but are designated by the letters F.

Each fuse is indicated with a current rating and designation. This allows you to use a new fuse with parameters that meet the requirements of the equipment connected to it.

First additional block

Inside the central panel there is the first of two additional blocks provided for the VAZ 2110. You can find it at the bottom left on the front passenger side.

This block provides three fuses. Each of them has the same power rating - 15A.

1. The first fuse is responsible for your vehicle's ignition and controller module.
2. The second protects the mass air flow sensor, heating sensor, speed sensor and purge valve.
3. The third is necessary to ensure protection of the injectors, as well as the fuel pump. So if problems arise with the fuel pump, the first thing we recommend is to check the condition of the fuse responsible for it.

Location of the additional block
Plus, the same block includes three relays:

• Relay number 4 is responsible for the electric fan;
• Relay number five is the electric fuel pump;
• The third relay is part of the ignition protection group on your VAZ 2110.

Second additional block

The second additional block should be looked for already in the driver’s feet, on the right. Behind the protective cover on the console you will find the required board.

There are three more components on it. They are responsible for:

• Immobilizer operation;
• Additional optics (mostly fog lights);
• For the operation of the car's central locking control.

How to use a cigarette lighter so that it works for a long time

If you use your cigarette lighter correctly, you will maintain its usability for a long time.

First of all, you should not connect to it powerful consumers such as a compressor, which many now use to inflate wheels or blow air into the power unit. It is more correct to power this device through a rechargeable battery.

In this way, you will protect the wiring and fuses from overloads, and, therefore, they will not overheat, burn out or melt. Some craftsmen install a separate socket in the car for such devices - this is very forward-thinking and effective.

Also try not to stick adapters into the VAZ socket if it turns out that they are too thick - this will quickly break the core, which is made of ceramic.

Replacing the cigarette lighter fuse

It would seem that what’s wrong with replacing the fuse, I pulled it out and inserted a new one. But no. Here is the correct procedure for replacing a fuse:

1. Turn off the car ignition.
2. Disconnect the ground from the car battery.
3. Carefully remove the blown fuse using special pliers. If they are not there, then use pliers (pliers).
4. The new fuse must be installed so that it is designed for the same current strength that was on the old blown fuse. For example, on the PCB it says 20, which means that it can withstand up to 20 Amperes. If you install a more powerful one, then the fuse will be able to withstand load surges, but the cigarette lighter itself may burn out. The fuse can be inserted from either side.
5. An old burnt-out fuse will have a burnt-out thread; you can look and find out whether it is the cause of the cigarette lighter failure. It also happens that the cause may not be a PP, but a broken wire. If the fuse is intact, you need to test the wiring with a multimeter.
6. Close the block cover.
7. We connect the disconnected negative wire back to the battery terminal.
8. Turn on the ignition and check the functionality of the cigarette lighter.

Inspection of cigarette lighter wiring

If after replacement the protective element burns out again, you should look for the cause elsewhere.
It lies not in the VAZ cigarette lighter fuse, but in faulty wiring. If the car is old or due to improper manipulation of the electrical system, the wires may shorten and burn out, or an open circuit may occur in the circuit itself, causing the cigarette lighter fuse to trip. It is advisable to inspect the cables for kinks or abrasions. This failure should be diagnosed using a multitester. The wires coming to the cigarette lighter are tested for resistance. If there is no power, then one of the cables is broken.

To repair the cigarette lighter on a VAZ, you will need a soldering iron with rosin and tin, working cables and insulating tape.
