Relay and fuse block VAZ 2106: decoding of circuits. VAZ 2106 fuse diagram

The electrical circuits of VAZ 2106 consumers are protected by fuses located in a special block. Low reliability of fuse links leads to periodic malfunctions and malfunctions of electrical appliances. Therefore, sometimes it is necessary to change both the fuses and the unit itself to a more reliable one. Repair and maintenance of the device can be carried out by every owner of a Zhiguli without visiting a car service center.

Description

Fuse number 1 at 16A is responsible for the operation of the cigarette lighter.

Scheme

The black box and relay are first checked and carefully inspected, and only then replaced with new ones. On the inside of the lid there is a diagram of the box that anyone can use.

Attention! On the “six” the fuses go from left to right. This can be seen in the provided diagram.

1. (power - 16A) - responsible for sound, front door alarm lights, lamps, cigarette lighter, clock;
2. (power - 8A) - controls the relay, heater, windshield electric motor, windshield wipers;
3. — controls the high-beam headlights on the left side and the control lamp;
4. — controls the high-beam headlights on the right;
5. — responsible for the operation of the left low beam headlights;
6. — controls the right low-beam headlights;
7. — responsible for the left front and right rear dimensions, and for the lighting of the rooms;
8. — monitors the operation of the right front and left rear lights, as well as the engine compartment lighting and warning light;
9. — responsible for rear traffic lights, turn signals, luggage compartment lighting, oil pressure indicator, brake light, tachometer;

The diagram of a regular VAZ 2106 fuse box and the diagram of the new model box are very similar. The difference is in the details themselves. The usual “black box” uses blade fuses, while the new type unit uses flag fuses.

Relay

The turn and hazard warning relay for 2106 is located behind the instrument panel, behind the tachometer. Not far from it , the rear window heating relay and the parking brake warning lamp breaker relay (PC 492) are attached.

The wiper relay on the car is located in the driver's feet on the left side under the trim.

The low beam (B) and high beam (A) relay is attached to the mudguard of the right side member under the hood.

Next to them is a relay the battery charge indicator lamp (PC 702).

Under the hood, on the side member splash guard on the left side, there are a cooling system fan relay (90.3747-10, 113.3747-10) and a sound signal relay (PC 528) .

How does a standard six fuse work?

Let's consider the design and operating principle of a standard “six” fuse-link. Unlike a modern knife fuse, it consists of only two parts: a ribbed plastic cylinder that acts as a body, and the insert itself, made of low-melting metal, located outside it. The contacts of the VAZ-2106 mounting block are made of copper (brass) and also have an open arrangement. From the point of view of electrical engineering, such a design cannot be called either reliable or safe, since all conductive elements, in fact, are not protected in any way.

Not protected by fuses

• Starter
• Ignition system
• Battery charging circuit
• Low beam relay
• High beam relay

Types of fuses

A competent choice of fuses will save VAZ-2106 owners from serious problems. Incorrectly selected parts can cause problems such as vehicle fires. When choosing these parts, you should pay attention to the current strength in them, which is expressed in Amperes. Fuses of different amperages have corresponding digital markings and also differ from each other in color. For example, brown ones have a rating of seven and a half Amperes, blue ones - 16A, green ones - 20A. It is important that the ratings of each part coincide with the manufacturers' recommendations.

VAZ 2106: fuses. VAZ 2106 fuse diagram

On VAZ-2106 cars, fuses were used of the old type, cylindrical. They protect electrical circuits, but the design has many disadvantages.

The location of the fuse box is good - near the driver’s left foot, away from moisture and direct sunlight. If we compare it with the VAZ-2109, in which the mounting block is located in the engine compartment, the six has a clear advantage.

Every VAZ-2106 owner needs to know which fuse protects which circuit.

Purpose of main unit fuses

The fuses are located on the main (upper) and additional (lower) ones:

1. F1, designed for a maximum current of 16 A, is necessary to protect the power circuits of the cigarette lighter, sound signal, interior lamps, clocks, brake lights, and light warnings about open doors.
2. F2, response current 8 A, allows you to protect the circuits of the windshield wiper and its relay, the electric washer motor and the heater.
3. F3, 8 Amperes, protects the power supply circuit of the left high beam headlight and the light control lamp.
4. F4, current 8 A, right headlight (high beam).
5. F5, F6, 8 Amperes – left and right headlights (low beam), respectively.
6. F7 – side lights (right rear and left front), light in the luggage compartment, license plate illumination, instrument cluster, cigarette lighter. Rated current 8 A.
7. F8 – side lights (left rear and right front), lamps under the hood and control panel on the dashboard.
8. F9 – designed to protect the power circuits of oil pressure, fluid temperature, gasoline level, and reserve lamp indicators. It also supplies power to the warning lamp, which signals that the handbrake has been applied, as well as an emergency level of brake fluid, a lack of battery charge, and the closing of the air damper. The XX solenoid valve, tachometer, reverse lamps, glove compartment lights, rear window defroster relay are also powered from this fuse.
9. Fuse F10 supplies power to the voltage regulator. Rating – 8 Amperes.
10. F11, F12, F13 – reserve.

Additional fuse block

1. F14 – fuse for protecting the power circuit of the rear window heater. Rated operating current 16 A.
2. F15 – electric motor for cooling the radiator. Current 16 A.
3. F16 – hazard warning lights and direction indicators.

Wiper relay and fuse

VAZ-2106 fuses protect power circuits by controlling electromagnetic relays. One of the main ones is the windshield wiper relay, which is powered through fuse F2.

With its help, the wipers do not work constantly, but intermittently. It is much more effective to control low-current circuits than power ones.

The relay is located under the dashboard, on the left side of the car interior. Replacement is carried out in this order:

1. Remove the seal on the driver's door pillar flange.
2. Pry up the upholstery and remove it.
3. Remove the holders installed on the side. Be sure to install new holders during installation.
4. Bend back the sound insulation.
5. Disconnect the block with the relay wires from the main harness. The connector is located at the bottom of the dashboard.
6. Remove the two screws that secure the relay housing to the body.

After removing the old relay, install a new one in its place. The work is performed in reverse order. If replacing the VAZ-2106 fuses responsible for the operation of the windshield wiper did not help, then be sure to check the integrity of the wires and relays.

Direction indicators and hazard warning lights

There is one drawback in the car - the VAZ-2106 fuses are located in the passenger compartment, but the relays are scattered throughout the engine compartment. The breaker responsible for the operation of the direction indicators is located on the partition in the engine compartment opposite the dashboard. Main breakdowns of the alarm system:

1. Fuse F16 is faulty. Check it with a multimeter and replace if necessary.
2. Frequent turning on of the control lamp indicates that one of the repeaters or indicators is faulty.
3. A relay malfunction leads to complete failure of the warning system.
4. If the alarm button breaks down, it does not allow the indicators to turn on.

To replace, you need to remove the instrument panel, then unscrew the nut using a 10mm socket. After this, disconnect the wire block and remove the relay. Install the new one in reverse order.

Turning on the headlights

To turn on the high and low beams, two relays are used, which are installed in the engine compartment, above the right mudguard. Removing the relay is very simple - just disconnect all the wires from it and unscrew the self-tapping screw with a Phillips screwdriver. Together with the bracket, the end of the ground wire is also attached to the body with a self-tapping screw.

Be sure to mark the location of the wires before disconnecting them from the electromagnetic relay. You can disconnect the wires one at a time and immediately install them on a new relay.

The replacement procedure is simple, so it can be completed in a few minutes. If the relay does not receive voltage, then the fuse links need to be replaced.

In the VAZ-2106 fuse circuit, elements F3-F7 are used to protect the power circuits of the low and high beam lamps.

Turns relay

An indicator breaker with 3 or 4 contacts is located behind the instrument panel on the partition of the engine compartment. The rating of the light bulbs connected to the circuit should be 21 A. It looks like a rectangle.

Generator fuse and relay diagram

To check the condition, you need to get to the thermostat, since it is located directly below it. It is attached to the generator with two screws and connected with a wire that often frays. This is true for the VAZ 2106 modification with an injector. Without it, the power supply to the generator excitation winding will be unstable.

Starter relay

You can easily find the retractor, as well as remove it yourself. You need to disassemble the starter using screwdrivers. You will need to correctly install a new one in its place.

High and low beam fuse and relay

The elements F5 and F6 are responsible for the first one, and F3 and F4 are responsible for the distant one. The power of each is 8 A.

Handbrake relay VAZ 2106: where is it located

On the parking brake.

Tachometer

It is protected by fuse F9 rated 8 A.

Radio tape recorder

It is connected to one of the backup fuses.

Washer

The protective element is marked F2 and is rated at 8 A.

The relay is located behind the dashboard of the VAZ 2106, has a round shape and is made of aluminum.

Fuse F1

If the interior lighting or socket does not work, the 16 Amp fuse element that is responsible for them may have burned out.

Typical symptoms of a faulty fuse

• The fuse has changed color, pinholes are visible, the predominant color is black. A symptom characteristic of old-style modules. The new ones don’t have this, the design is different;
• An indicator on the dashboard indicates a malfunction of one or another equipment;
• The mechanisms are not active when the engine is running, the ignition is on, and the battery is working;
• A burning smell can be heard in the cabin, emanating from the place where the power supply unit is fixed;
• The modules feel hot to the touch, with an unnatural temperature.

Additional fuse block

1. F14 – fuse for protecting the power circuit of the rear window heater. Rated operating current 16 A.
2. F15 – electric motor for cooling the radiator. Current 16 A.
3. F16 – hazard warning lights and direction indicators.

When connecting a new unit, be sure to use the VAZ-2106 fuse diagram. This will prevent the elements from being mixed up.

How to identify a blown fuse

1. visual inspection;
2. diagnostics with a multimeter.

Visual inspection

It is necessary to check the integrity of the metal partition of the element. If it is broken, then the insert is burned out.

Diagnostics with a control and a multimeter

When an element burns out, the integrity of the jumper is not always compromised. It wouldn't hurt to check with a multimeter. The probe is applied to the fuse, the device is turned on, and if it shows resistance other than 0 Ohm, then the element is broken.

Fuse box problems and troubleshooting

On the VAZ "six" fuses are installed in two blocks - the main and additional ones. Structurally, they are made of a plastic case, fusible inserts and holders for them.

VAZ 2106 fuse blocks: 1 - main fuse block; 2 - additional fuse block; F1 - F16 - fuses

Both devices are located in the cabin to the left of the steering column under the dashboard.

The fuse box on the VAZ 2106 is installed to the left of the steering column under the dashboard

How to identify a blown fuse

When a “six” has a malfunction with one of the electrical appliances (windshield wipers, heater fan, etc.), the first thing you should pay attention to is the integrity of the fuse links. Their serviceability can be checked in the following ways:

• visually;
• multimeter.

Visual inspection

The design of the fuses is such that the condition of the fuse link can be used to determine the operability of the part. The cylindrical elements have a fusible connection located outside the housing. Even a car enthusiast without experience can determine its destruction. As for the flag fuses, their condition can be assessed by looking through the light. A burnt-out element will have a broken fusible link.

Determining the integrity of the blade fuse is quite simple, since the element has a transparent body

Diagnostics with a control and a multimeter

Using a digital multimeter, the functionality of the fuse can be checked by voltage and resistance. Let's consider the first diagnostic option:

1. We select a limit on the device to check the voltage.
2. We turn on the circuit being diagnosed (lighting devices, wipers, etc.).
3. We touch the fuse contacts one by one with the probes of the device or control panel. If there is no voltage at one of the terminals, it means that the element being tested has failed.

Table: VAZ 2106 fuse ratings and circuits they protect

Subtleties and nuances that a car enthusiast should know about

• The location and number of the module is indicated on the power supply cover;
• Before replacing a module, check the equipment connected to it for serviceability;
• If the module is intact and the equipment is working properly, but no current is flowing, there is most likely damage in the electrical supply circuit;
• The ignition and electric fan motor activation relays are not protected by fuses;
• If you install one with a lower rated current instead of the original module, then most likely the fuse link will burn out. This is not a defect, but a sign that the voltage readings do not correspond;
• Installing a module with a high rated current will increase the likelihood of failure of the equipment assigned to this module;
• It is strictly forbidden to use foil as a conductor instead of a power supply;
• If a fuse with a similar amperage blows at the same time, then there are big problems with voltage in the system. Contact a service station for diagnostic work.

VAZ 2106 fuse box pinout, diagram

If you have any problems with electrical equipment: the low or high beams have disappeared or are not working, the turn signals, stove, cigarette lighter, fan, wipers are not working, the signal has disappeared, etc., then this could all be the reason that the fuse has blown. This means it needs to be replaced.

To do this, you need to know the location of the mounting block. And it is located under the steering wheel, on the left side. In order to understand what the VAZ 2106 fuses are responsible for, you need to look at the simple pinout of the old fuse block (FB) and see the description below.

Below is a picture of what the Eurobloc looks like in real life.

Replacing the VAZ 2106 fuse box with a “Euroblock”

And finally, for those who don’t know how to replace the old model with a “Euroblock”, the following information. There is nothing complicated here.

You just need to follow the instructions below:

1. First you need to disconnect the minus from the battery.
2. Use a 10mm wrench to unscrew the old power supply. In this case, the wires are not disconnected.
3. According to the diagram above, wires and jumpers are installed.
4. It is important to install jumpers only on those wires that carry voltage from the engine compartment.
5. Jumpers are installed between pins 3-4, 5-6, 7-8, 9-10, 11-12.
6. Next, the wires are removed one by one from the old device and attached to the Euroblock.
7. At the end, check that the connection is correct (for example, with the low beam on, if you pull out the 5th fuse, the left headlight should go out).
8. All other circuits are also checked.

The video below clearly shows how to replace an old power supply with a Euroblock.

Replacing fuses in the mounting block for VAZ 2107

To replace, you need to open the cover of the mounting block. The serial numbers of the pin fuses are indicated on the underside of the cover and on the panel of the unit. There, on the cover, the symbols of the protected circuits are indicated. In the old-style mounting block, which is still equipped with some cars, the fuses are arranged in numerical order from left to right. The status of the pin-type fuse is visible through the window at the top.

To replace the VAZ 2107 , there is a special plastic tweezer in the mounting block; if it is not there, use pliers.

Replacing the additional fuse for the headlight cleaner (they are located on the wires next to the gearmotors and protect the motor winding):

Removal and replacement process

There is nothing difficult in the process of changing power supply parts, so we will not describe this process. But we will tell you how to replace an old-style power supply with a new-style device.

1. First of all, disconnect the battery. Now open the driver's door and use a screwdriver to pry out the two fasteners securing the decorative interior trim. Move it to the side and you will see a block. Using a Phillips screwdriver, unscrew the screws securing the power supply. Do this carefully so that the wires do not fly off the terminals in the process.
2. Once the power supply is unscrewed, move it down. But do not pull it too hard to avoid breaking the wires. Note! Jumpers must be installed on those wires through which voltage comes from the engine compartment. Do not connect the jumper after the fuse itself, otherwise this will result in voltage passing through one part to power several electrical components.
3. The order of installation of jumpers should be as follows: 3-4, 5-6, 7-8, 9-10, 11-12, 12-13.
4. Now you need to remove each wire one by one, starting with the first fuse from the old power supply, and mount it on the new one. Perform this operation with each contact, until the very last wire. When all the contacts are in place, you should check whether you did everything correctly. In particular, you need to turn on the voltage source and remove the corresponding fuse. If the device stops functioning, then all actions were performed correctly. For example, turn on the low beam headlights and remove one of the power supply elements responsible for the left or right headlight. If it goes out, then you did everything right.
5. Check each fuse in the same way. If, when dismantling the element, the device continues to work, then the jumper is most likely installed incorrectly, so double-check the connection diagram.

This completes the replacement of the power supply with a new type device. As you can see, there is nothing difficult about this, but if you are not sure that you will do everything correctly or cannot distinguish the blue wire from the red or green, then entrust this matter to an electrician.

Location and electrical diagram

The power supply itself consists of two lines with fuses, which is installed in the car interior and attached to the body with two nuts. In particular, it is located on the driver's side under the instrument panel. Below is a diagram of the device, as well as the purpose of each element.

As you can see, almost all circuits of a domestically produced car are protected using fusible devices. However, there are exceptions here too. In particular, we are talking about:

• starter retractor relay - it is missing;
• the power circuit of the relay coil, which ensures the operation of the radiator fan of the cooling system, is also not protected;
• the ignition coil is also not protected by a relay;
• If your car has an old-style power supply, then it does not have a power supply circuit for the switch and a Hall sensor.

The element installed in the power supply is designed for a certain voltage in the wiring. This voltage is calculated using a simple formula - the voltage of all energy consumers in the wire must be multiplied by the reserve number, ranging from 1.2 to 1.5. So what's the purpose? In order for the operation to be stable, the nominal values ​​of the block elements must match.

It should be added that very often owners of 2106 make mistakes by using an ordinary coin instead of a fusible device. It is better not to do this, since a short circuit may occur in your car at any time. Therefore, old-style power supplies, like any other machine component, also require periodic maintenance. Due to design features, that is, weak power supply holders or tips that regularly oxidize, you may notice the contact part burning.

Thus, due to the increased contact resistance, overheating occurs and the contact condition of the element deteriorates. This may result in additional problems with the vehicle's wiring. To prevent this from happening, you should periodically, at least twice a year, inspect the power supply unit as a whole. Clean the mounting sockets, inspect the power supply and promptly replace failed fuses.

But this all applies to old-style power supplies. Some owners of these car models, taking into account the periodic problems with the old-style power supply, change it to a new one.
