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.

Electromagnetic relays

To relieve the car switch contacts from high current consumption, electromagnetic relays are used in the electrical circuit. There are 8 of them in total:

• K1 is responsible for the serviceability of the lamps;
• for turning on the front window wiper - K2;
• for turn signals and hazard warning lights – K3;
• for low beam headlights - K4;
• for turning on the high beam - K5;
• for heating the rear window - K7;
• for fog lights located at the rear - K8.

The block contains relay K6, which is additional. Before installing a new element into the system, check the wiring for short circuits, otherwise the parting that is protected by the fuse element or the fuse itself may fail. The described block is the main one, but the only one in the VAZ-2112 electrical circuit.

To ensure safe and stable thermal conditions of an internal combustion engine, precise operation of the cooling system is required. The slightest failure will lead to overheating of the engine, which can lead to burnout of the head gasket or failure of the piston group elements.

The radiator fan is one of the key components of the car cooling system. Its role is to promptly force cool the liquid in the radiator. Problems with turning it on are a common occurrence for our cars.

In this article we will talk about possible reasons why the VAZ-2110 cooling fan does not work, and also consider options for eliminating them. But first, let's understand its design and operating principle.

Structurally, the radiator fan consists of:

An electric motor with an impeller on a shaft is installed inside a rectangular metal frame, with which it is attached to the back of the radiator. When voltage (12 V) is applied to the contacts of the drive, it begins to work, rotating the blades and creating a directed stream of air, which, in fact, cools the antifreeze or antifreeze.

The control of forced radiator airflow in carburetor and injection engines of the VAZ-2110 is significantly different. Firstly, the fan switch located on the radiator housing is responsible for everything. It is set to a certain coolant temperature. Usually this is 105-107 o C. When the coolant heats up to this temperature, the sensor is triggered, sending a signal to the fan relay. It closes the electrical circuit, driving the electric motor.

Turning on the cooling fan of a VAZ-2110 with an injection engine occurs somewhat differently. In engines equipped with an electronic control unit, there is no sensor on the radiator. Its place was taken by a temperature sensor located on the thermostat pipe. When the coolant heats up to a temperature of 105-107 o C, it sends a signal directly to the controller, which makes the decision to turn on the fan. It transmits an electrical impulse to a relay, which turns on the electric drive.

If the VAZ-2110 cooling fan does not work, do not rush to contact a car service center. You can determine the cause of the malfunction yourself. Moreover, it is not at all necessary to have special skills for this.

The cooling system fan may not turn on due to:

• electric drive malfunctions;
• blown fuse;
• faulty thermostat;
• a failed fan switch (temperature);
• faulty relay;
• broken electrical wiring;
• faulty expansion tank plug.

A common reason why the VAZ-2110 cooling fan does not work is a malfunction of its drive (electric motor). This may be wear of the brushes, breakage or short circuit of the windings, lack of contact in the connector, etc. It is not difficult to check the drive. To do this, simply disconnect the fan from the car's electrical circuit and connect it directly to the battery. If it does not turn on, the problem is definitely in it, but if the engine starts, you need to continue troubleshooting.

Operating principle of the fuse

Fuses are used in vehicles and are selected according to their rated load capacity. In the event of an emergency, when the voltage increases, the fuse link breaks and opens the electrical circuit.

The process of self-destruction starts in the event of:

• Short circuit - occurs if the insulation of conductive parts has been broken or the devices have been connected incorrectly. The problem of frayed insulation cables in a car is generally one of the most common causes of blown fuses.
• Incompatibility of the power of the consumer device and the rated current allowed for a specific electrical circuit. This problem is faced by those who decide to install additional electrical equipment (lighting, radios, etc.) in their car. Such powerful energy consumers are powered by basic wiring that is not designed to handle such high amounts of current. Due to excess current power, the wires melt and lead to a short circuit, which damages the fuses.

VAZ 2112 fuse box

If some devices on your VAZ 2112 car have stopped working, fuses or relays may be to blame. At the very least, the first thing you need to do is check them, and then draw some conclusions regarding the malfunctions. Correct diagnosis of many electrical problems will allow you to accurately determine the cause of the inoperability of a particular unit. To find out what fuses and relays do and how to find the right one, read this article.

What are fuses

Automotive fuses are an important part of the electrical circuit. They protect consumers from various malfunctions, and also protect wiring and the car as a whole from fires.

Let's say an inexperienced motorist is repairing a car. He forgot to disconnect the negative terminal of the battery before performing the work and during the repair he accidentally shorted the positive wire of some consumer to the ground of the car. A short circuit has occurred. At this moment, the current becomes maximum, and the conductor begins to heat up.

Such a phenomenon can damage the protected device, battery, or even cause a fire in the car. To prevent this, fuses are used. They look like this:

Additionally, fuses can shut down a circuit if a fault occurs.

Their color was not chosen by chance. It is a marking of the rated current for which this fuse is designed. If this rating is exceeded, the fuse inside it burns out. The denomination depends on the protected consumer or group of consumers.

Where is the cooling fan relay on the VAZ-2110

In order for everything to work correctly in the VAZ-2110 engine, it is necessary to maintain a certain temperature.
This temperature range is achieved using a cooling fan, which, as a rule, comes with an electric drive. Its activation and deactivation is carried out automatically. Moreover, if the machine contains a carburetor engine, then TM 108 is used, and in the case when an injection engine is used, a controller is used. This article will tell you where the cooling fan relay is located on a VAZ-2110 car. If the fan is controlled by switching on, it is important that the temperature setting of the housing sensor is observed. The sensor is considered faulty when its temperature has reached the switch-on level, and the cooling motor has not worked. To check, you should close the contacts of the sensor, then check whether the fan works; if so, then the sensor needs to be replaced with a new one.

There are times when closing the contacts does not help and the fan still does not work, then according to the diagram, the integrity of the fuse with the supply wires is checked.

In order to start the cooling fan of the machine in which the injection engine is located, an electronic controller is used. Temperature conditions are pre-entered into the device software and range from 100 to 105 degrees. If the temperature sensor is faulty, then a system error is selected on the controller, and the cooling fan is activated when the car engine is turned on.

A number of breakdowns occur in which the controller does not detect the breakdown, and as a result, when the required temperature reaches 105 degrees, the fan simply does not start. To perform the test, remove the temperature sensor connector while the engine is running. If the system is working properly, the sensor will start the cooling fan, and by returning the connector to its original position, the fan will turn off. In case of damage to the circuit, check the quality of the relay, fuse and underwater wires. Everything must be installed exclusively according to the diagram. To carry out express checks, they bridge terminals 30 and 87 of the fan relay, which are located in the heating shaft. To make it easier to find, look in the passenger seat area.

When the fan is activated, connect the control lamp, the housing and output 86 of the relay, then the relay will operate and the fan will start automatically. At the same time, it is necessary to manipulate such a circuit only when the relay is located in the connector block. Here it is recommended to look at the controller and the wire, the relay connector with pin 46, if there is a breakdown in one of them. If a specific click of the relay did not occur, but a positive signal goes from the main relay to pin 85, or there was a click, but the cooling fan did not start, then this indicates a breakdown of the relay and the need to replace it.

Fuse threshold

From the above, it is clear that the fuse in the car is destroyed if the rated electricity value is exceeded. The fuse part overheats and burns out.

The rated current of the fuse is calculated using the formula: Inom=Pmax/U.

• Inom is the nominal current value, which is measured in Amperes;
• Pmax is the maximum possible load that a particular device can handle. Power is indicated on devices and measured in Watts;
• U is the network voltage level. This indicator is measured in Volts. The voltage level in the car network is 12 Volts.
