Diagram and location of the VAZ-2110, VAZ-2111 and VAZ-2112 fuse box

VAZ 2110 2111 2112 (Lada 110 111 112) - a family of cars produced in 1995, 1996, 1997, 1998, 1999, 2000, 2001, 2002, 2003, 2004, 2005, 2006, 2007, 2008 and 2009 with sedan and hatchback bodies and a station wagon mainly with 8 and 16 valve gasoline engines ( injector , carburetor). In this article you will find a description of the fuse and relay blocks of the VAZ 2110 2111 2112 with diagrams , photographs and their locations. Electrical connection diagram. Let's highlight the fuse responsible for the cigarette lighter.

The purpose of fuses and relays in your VAZ 2110 (2111 / 2112) relay may differ from those presented and depend on the year of manufacture. The current purpose can be printed on the block itself.

What are the VAZ 2110 fuse box relays responsible for?

K1 – relay for monitoring the health of light bulbs; K2 – front wiper relay; K3 – repeater and alarm relay; K4 – low beam relay; K5 – high beam relay; K6 – additional relay; K7 – relay for turning on the heated rear window; K8 – backup relay (not installed on 110 series vehicles);

F1-F20 in the diagram are fuses. The circuits in the car are protected by fuses based on a certain rated current (in A). The battery charging circuit, generator circuit, ignition and engine starting are exceptions.

To replace a faulty fuse, first find the one that has blown, then eliminate the reason why it was damaged and then install a new one. Below is a list of fuses and information on each one.

* Never replace fuses with jumpers, this can lead to failure of various components and elements, including failure of the wiring tracks in the fuse box and even a car fire.

Voltage problems

A common problem when starting an engine is low voltage or no voltage at all. First of all, you need to check the fuses. Not every car depends on the safety system to start the engine, but it is still worth doing.

Over time, any wiring connections to the battery can become oxidized or dirty. This will result in no current flowing. It is necessary to clean the battery terminals and wire connections with a dry cloth or sandpaper. After that, try to start the car again.

If the terminals and wires are in order, then you should check the battery. A dead battery is a common problem. You can check the battery charge with a tester or by external signs. To check the performance of the battery, insert the key into the ignition and try to start the engine. A “weak” starter is a clear sign that the battery is discharged.

There are several ways to fix the problem with a dead battery. Light a cigarette from another car or try to start the car from a tow. The second method is only suitable for cars with a manual transmission. If the car does not start, you will have to remove the battery and charge it. Do not forget that the battery life is no more than 5 years.

Problem with starter and ignition switch

The battery may be charged and the high voltage wires are fine, but you still won't be able to start the engine. Then the cause of the malfunction should be looked for at the ignition switch or starter.

To check the serviceability of the ignition switch, you need to insert the key into the ignition switch and turn it to the second position. If the red lights on the dashboard do not light up, then the ignition switch may be faulty. You can check it in another way. When you try to start the engine, turn on the headlights; if they start to dim, it means the ignition is in working order. A malfunction of the ignition switch can be eliminated in most cases by replacing the switch.

Corrosion and dirt damage not only the wires on the battery, but also the starter. To check the starter's performance, you will need a tester and an assistant. The electrical tester is connected to the wire that supplies the car's starter. At this moment, the assistant should try to start the engine. If the tester shows that there is electric current on the wire, but the starter does not crank, then this problem can be solved by replacing the starter. Attention! Do not forget about precautions, do not touch wires and other parts of the engine with bare hands. It is best to carry out this procedure while wearing dielectric gloves.

There are times when the starter turns, the car does not start. What to do in this situation? To answer the complex and trivial question of why the car won’t start, you need to check other components of the car. Lack of spark is another option why the engine refuses to start. Checking the spark plugs should be the last thing on your mind; first you need to deal with the ignition coil.

Circuits protected by additional fuses (all fuses are 15 A) on the VAZ-2110:

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:

Problems in the fuel system

Car won't start? The starter cranks at full power, but the engine still won't start? Then the problem should be looked for in the fuel supply. Modern cars often use electronic fuel delivery. The problem is that it will be difficult to diagnose on your own. Diagnostic equipment is expensive, and you need to go to a car service center. But there are signs by which you can understand what kind of malfunction is in the fuel system, thereby saving you money on diagnostics.

The very first thing you should do is check all the electrical wires under the hood. It will take a lot of time, but it's better than paying a lot of money for diagnostics. Each injector that supplies fuel to the system has its own separate wire. Check all wires with a tester, and also pay attention to the insulation.

Car won't start? The causes of malfunction when starting the engine may be in the operation of the fuel pump. Its performance can only be checked using special equipment, which not every driver has. You can try to find out the cause by checking the voltage on the positive wire of the fuel pump. It may be missing due to a faulty fuse. If the fuse is good and there is no voltage in the wire, then this problem can be solved by replacing the fuel pump motor relay.

A working fuel pump does not mean that the fuel system is fine. The filter may become clogged and not supply fuel. To prevent this from happening, it should be changed every 20,000 km. You can replace all these parts yourself. Why doesn't the car start if the entire fuel system is in good condition? We don’t despair and look for the problem further.

Spark plug

Spark plugs are designed to ignite fuel-air mixtures. They come in different types: spark, incandescent, semiconductor and others. If your car does not start, then turning the starter for a long time will lead to flooding of the spark plugs. After which they will need to be changed. Otherwise, working with flooded spark plugs will harm other parts of your car.

What to do if they cannot determine the reason why the car does not start?

Attention. We advise you, fellow motorists, to initially, for electronic diagnostics of your car, immediately contact specialized dealership auto centers that service only your or your particular brand of car (office dealer and others). Only they can guarantee you a professional approach to diagnostics and classified repairs of your vehicle.

Typically, such car services have a full range of electronic equipment and expensive software for car diagnostics. Indeed, in ordinary services and in the same garages, despite the high classification of some certain specialists, there is often no highly specialized expensive equipment and software that is necessary for quick troubleshooting.

For example, the cost of some specific software intended for diagnostic equipment can cost several hundred thousand US dollars. (!) Unfortunately, most car services (especially garage technicians) cannot afford to purchase such “autosoftware” for themselves. It is too expensive.

Other reasons why the car won't start.

Having thus checked all the main car systems that could affect the car’s engine starting, you, dear motorists, should know that there are still a number of specific tips that you can resort to and perform them yourself to find out why your car does not start. If you have patience and time to do this kind of troubleshooting, you can do the following yourself:

— Loose starter mounts: Sometimes the starter mounts become loose, which can cause a lack of ignition.

— Bad injectors: A malfunctioning injector affects the entire fuel system, which can cause the engine to fail to start. Especially when starting when the engine is still warm.

— Faulty starting valve: If this part of the car is in a faulty condition, then when starting the engine (especially in cold weather), a malfunction may occur and the car simply will not start. This faulty valve can also cause uneven operation of the engine after it warms up.

— Chips on the flywheel: The starter not only ignites the car, but also transmits torque to the flywheel, which is connected to the transmission. If the flywheel teeth are chipped or damaged, when the starter rotates, you can hear a characteristic sound (squealing, creaking) produced by the flywheel itself which has a defect. It is noteworthy that a similar problem can also be the reason for the engine failure to start.

— Immobilizer or Engine Control Unit (ECU) malfunction: If your vehicle's main computer malfunctions, it can significantly affect the performance of the ignition system itself and fuel injection. Including, if any electronic system malfunctions, then in many modern cars the engine management system can simply block the engine from starting itself. Also, a common reason for failure to start the engine is a specific malfunction in the electronic anti-theft system (immobilizer).

When it breaks down, as a rule, this electronic unit simply does not recognize your key, which contains a chip with an electronic code that disables the security system.

Unfortunately for us, you simply cannot check all these electronic systems yourself, since expensive equipment is needed to diagnose the electronics of the machine.

Timing problems

The timing belt is responsible for the operation of the engine in the car. Sometimes a metal chain is installed instead of a belt. Both are responsible for rotating the crankshaft and camshaft.

When using a car, every part wears out over time. The timing belt is no exception. Under constant load, it wears out and can rupture. Such a violation will lead to damage to the engine valves, and subsequently to its breakdown. And then a problem arises: the starter turns, the car does not start. What to do? A complete timing belt repair or valve belt replacement can be quite expensive. Therefore, to prevent such a problem from happening, it is advisable to change the belt every 2 years (this is approximately 60,000 km).

No compression

Does the car start and stall or not start at all? This may happen if the engine lacks compression. Compression in an engine is the ability to maintain the pressure that is created in the combustion chamber when the piston rises to its highest dead center. Compression is measured with a special device - a compression meter. Whether you need such a diagnosis can be determined by external signs. Blue smoke from the exhaust pipe, unstable engine operation or idle speed does not stand still - these are all reasons for weak compression. Such an engine will consume more oil and fuel. If you put your hand on the exhaust pipe and small drops of oil remain on your hand, then this is another symptom of engine failure. It is best to contact specialists. After all, the cause could be a burnt-out piston.

The engine does not start in cold weather

Starting a car in severe frost is difficult, but not hopeless. If the outside temperature is -15 °C or lower, then any battery loses 50% of its power, this is another problem why the car is a bad car, you need to turn on the high beam for 10-15 seconds. This will allow the electrolyte in the battery to warm up to produce additional energy.

Attention! Never turn the starter for more than 5 seconds. Otherwise, there is a chance that the battery will die completely or the spark plugs will flood, which is unacceptable at low temperatures. If the car is in good condition, then on the 2-3rd try everything will work out and your car will start.

It happens that the battery is completely dead. This can be understood if the car stalls and does not start. In this case, you will need a cigarette lighter. If the car has an injection engine, it will be more difficult to “light” due to the large number of electronics. You can “light” from another car even when its engine is running. The main thing is not to confuse polarity and order. However, if you made a mistake and mixed up the signs, run quickly to get a new battery.

After connecting to the “donor machine” you need to wait 10-15 minutes for your battery to charge. Afterwards, we disconnect from the car and try to start. If the engine starts, give it a couple of minutes, otherwise it will stall.

Remember that starting the engine at sub-zero temperatures is equal to 500 km. Take care of your car.
