VAZ 2110 diagram

Colored wiring diagrams for the VAZ 2110 (injector and carburetor engine) are provided with a description of all elements for various modifications. The information is intended for self-repair of the car. Electrical circuits are divided into several blocks for ease of viewing via a computer or smartphone; there are also circuits in the form of a single picture with a description of the elements - for printing on a printer in one sheet.

There are two types of electrical wiring for the VAZ-2110: carburetor and injector. There are slight differences, but the basic principles of operation and wiring are the same. Depending on the location, the wiring differs into: under the hood and in the cabin. All electrical equipment of the car is connected using wires of a certain color. Each element has its own wiring harness through the blocks and fuses.

Carburetor engines

The very first VAZ-2110 cars, produced since the mid-nineties, were equipped only with engines with a carburetor injection system. Injection engines began to be installed at the beginning of the two thousandth. They are much better, they work more stable, but still many motorists still use cars with carburetor injection. Today they are not uncommon.

There are no significant differences in the electrical circuit between the injection and carburetor options. On carburetor “tens” the systems are almost the same as on injection ones. But you will definitely encounter a problem when replacing a carburetor with an injector. You will have to additionally lay several braids of electrical wiring. They are necessary to power the sensor system, electric fuel pump, on-board computer and other components.

VAZ 21109 “Consul” . 4-seater luxury limousine based on the VAZ-2110 car. In addition to the length of the body, the dimensions of the rear door were also increased, for more convenient entry and exit of passengers. Equipped with a 1.5 liter engine and R14 or R15 wheels. Overall dimensions: length - 4950 mm, width - 1700 mm, height - 1440 mm. Fuel consumption in the urban cycle is 9.5 liters per 100 kilometers.

VAZ 2110-91 . Modification of the VAZ-2110 with a 1308 cm3 rotary piston engine. The car could reach speeds of up to 240 km/h, and acceleration from 0 to 100 km/h took 6 seconds.

A car with a 16-valve injection engine in the Gran Lux configuration includes:

Electric windows;
Door locking;
Trunk lock lock;
Velvet seat upholstery;
Immobilizer;
Heated front seats;
Ventilated 14-inch brake discs;
Rear spoiler with additional brake light;
Fog lights.

Heated seats and rear window

These two systems are very similar to each other, as they consist of the same components:

Fuse to protect the circuit.
Electromagnetic relay for switching a power circuit.
Illuminated power button.
Wire harnesses.
Heating elements.

It is imperative to use electromagnetic relays. They are available in the electrical circuit for heated seats of the VAZ-2110. With their help, you can get rid of switching with a high current button.

As a result, the button on the dashboard switches only the low-current control circuits of the electromagnetic relay windings. The rear window heater has a similar design. If the car has heated rear view mirrors, then a similar scheme is used.

Wiring diagram for VAZ 2110 carburetor

In the instrument panel wiring harness, the second ends of the wires of white, black, orange, white with a red stripe and yellow with a blue stripe are connected to each other at the same points. The bends of the wires at the points of entry into the harness indicate the direction of their laying in the bundle.

Interior heating system

The VAZ-2110 stove consists of a radiator, fan, and air duct system. Using a fan, the radiator is blown and air (hot) is supplied to special channels. The electrical circuit of the VAZ-2110 heater also includes a damper position regulator. In essence, this is a regular stepper motor.

It allows you to move the damper, changing the angle of its opening, as well as the amount of cold air entering the heater from outside. The blower fan electric motor is connected through a specially designed switch. It has several positions, each of which corresponds to a specific rotation speed.

The fan speed is adjusted using resistances installed in the heater housing. These resistances are included in the power supply circuit of the electric motor. Switching occurs using a regulator installed on the instrument panel. On older cars of the tenth family you can still find mechanical damper drives. Similar designs are also found on “nines” and “eights”.

Electric fuel pump drive

The electric fuel pump is powered through separate fuses and relays. It is installed under the rear seat directly in the tank. Moreover, it is combined with a gasoline indicator sensor. The main components of the electrical circuit of the VAZ-2110 pump:

Electric motor driving the pump.
Electromagnetic relay.
Fuse.
Wiring harness.

When the ignition is turned on, the electromagnetic relay is activated, after which power is supplied to the fuel pump.

Gasoline is pumped into the system to a certain pressure, after which the electric pump stops. A pressure sensor installed in the fuel rail sends a signal to the electronic control unit. It is by these parameters that the control system understands at what point it is necessary to turn on or turn off the fuel pump.

Prevention measures

If you notice that the electrical circuit of your ten is not working correctly, first of all you need to seek help from an electrician. Or you can independently diagnose high-voltage wires; for this you need to use a multimeter.

The diagnostic procedure is carried out as follows:

First of all, the black wire must be installed in the left hole.
The red cable should be installed in the middle.
Next, the diagnostic device itself turns on. The multimeter must be activated in blue twenty mode.
Now you need to carefully connect the multimeter probes to each other.
If the arrow on the device display points to zero, that is, zero resistance, this indicates that everything is in order with the high-voltage wires. This means that the problem must be looked for elsewhere. If the multimeter needle on the dial points to one, this indicates that the resistance level is quite high and exceeds the norm. In this case, you can understand that the problem lies in a certain wire. Most likely it is interrupted or has poor contact. In order not to have to deal with repairs, the best option would be to purchase a new wire and install it.

When repairing wires, you need to use not only electrical tape, but also corrugated tape; it is more resistant to rubbing than electrical tape.

How to look for faults?

In case of almost any breakdown in electrical wiring, the first step is to diagnose the contacts. To check their condition, you need to carefully inspect all the wires that are laid in the harness. You can do this in several ways:

Visual inspection to determine integrity.
Full inspection of the integrity of connections and their reliability.
Checking the wires using a multimeter with the battery disconnected.

On carburetor and injection engines, it is imperative to pay attention to the wires that transmit high voltage to the spark plugs.

If they are damaged, the engine will run unstably. Signs of failure of high-voltage wires:

Extraneous noise when the engine is running.
The car may jerk while driving.
Gasoline consumption increases.
Unstable operation at low speeds.

Therefore, before sinning on any sensors, make sure that the high-voltage wires and the ignition module are in good condition.

According to the scheme described above, fuel regulation in a car is carried out. Moreover, it depends not only on the load of the valves in the engine, but also on the corresponding position relative to the throttle valve. With the help of a diagram of electrical wiring and valves, it is possible to understand which of the relays or fuses is malfunctioning and replace it in time. In this case, one of the main roles when supplying fuel is played by electrical equipment (controllers) that regulates the operation of the injector.

Starter connection

An electric starter is used to start the engine. It is a simple DC motor. The whole system works as follows:

When the ignition is turned on, the rotor winding of the generator is energized, resulting in a constant magnetic field being created around it. This is a necessary condition for the operation of the generator set.
As soon as the key is turned to the “Start” position, voltage is applied to the relay coil.
Together with the retractor relay core, the gear and overrunning clutch move along the starter rotor. As a result, the gear meshes with the flywheel ring.
At the same time, the core closes the power contacts inside the solenoid relay.
Voltage is applied to the starter winding, the rotor begins to rotate and spins the engine crankshaft.
The generator begins to produce current as the magnetic field rotates inside the stator winding.

Information that a motorist must know before replacing existing wiring

First of all, the car owner must know when and in what cases the car wiring is replaced. At the same time, it is also necessary to have information about the final operational life in order to objectively understand when the wiring may need to be replaced. List of the most common reasons that cause wiring to malfunction:

the appearance of cracks in insulation during a long period of operation;
oxidation;
corrosion;
fuse blown, etc.

Components needed to perform wiring replacement:

multivariate set of wires;
fuse block for VAZ 21104;
housing for the heating system;
various types of sensors: brake fluid, cooling system, etc.;
pads;
many terminals;
Of course, it goes without saying, duct tape.

A practical look at rewiring

So, a detailed step-by-step algorithm for replacing the wiring:

first you need to dismantle the front part of the cabin;
then you can deal with the proper degree of isolation, if there is a desire for it;
after which, you need to pay special attention to the front headlight switch;
The windshield wiper (see Replacing windshield wipers on a VAZ 2110 on your own) operates using its own mini-motor, the wiring of which must be checked for serviceability, since very often it simply becomes acidified;
understand all heating modes;
the connection of all electronic devices must be carried out strictly sequentially, by increasing the number of connected wires.

Note. Before disconnecting all electronic devices, it is necessary to draw your own conventional electrical circuit by hand in order to correctly make the appropriate connections in the future.

now it’s time to tackle the fuse blocks, or rather their installation;
most wires exceed the required length, so they simply do not fit into the allotted space;
the bracket is the most rational solution to the problem; it will allow you to successfully replace the fuses with new ones;
with the installation of a new fuse, the position of the front light indicator light, as well as the emergency warning light, will change;
the heater will also have to be affected: first you need to remove the old radiator and then disassemble it to make it possible to replace the fan;
Assembly is carried out strictly in reverse order.

Note. Before you begin the wiring replacement procedure, you need to find its current diagram. Otherwise, during the process of assembly and disassembly, you can quickly get confused, and you will have to send the car to a car service center.

The main advantages of the new wiring:

the emergence of a practical opportunity to connect any gadget;
longer service life compared to old wiring;
high degree of reliability of everyday functioning;
improving the quality and stability of electronic devices and much more.

It is always necessary to remember that installing homemade wiring is an easily feasible technical manipulation; the main thing is to understand all the necessary nuances.

The main objective signs of a car wiring fault

So:

the car engine does not start;

Note. If the essence of the malfunction lies in the ignition system, then one of the diagnostic signs is that the car will not start. Moreover, if the car starts poorly, but still starts, then problems with the wiring can be excluded from the list of possible causes.

the central ignition lock has stopped functioning properly;
the car’s electronics begin to function intermittently or do not work at all;
headlights function intermittently or do not function at all;
the characteristic smell of burnt rubber began to appear regularly in the car interior;
the battery discharges too quickly, although it was functioning properly before;

and of course, it goes without saying, multiple problems associated with the ignition system.

Practical example of wiring fault:

the engine suddenly began to function with noticeable interruptions;
at first glance it may seem that the essence of the problem lies in a malfunction of the ignition system;
however, a motorist with sufficient experience will not be able to immediately determine where the essence of the malfunction lies, since the cause of an interruption in engine operation may be the ignition system, or a burnt-out spark plug as a result of a wiring fault.

The instructions for replacing the wiring yourself are extremely simple, and the diagnostic process, in principle, does not present any significant practical difficulty. It is recommended to use photo and video materials during the replacement process. The main thing is to find the root cause of the problem in the wiring system. It is never too late to modernize VAZ wiring, and this, in turn, will allow you to use almost any modern high-tech devices for your car. The price of replacing the wiring yourself is significantly lower than the corresponding service at a car service center.

Topic: Resolved: What is the best way to replace the ECU and wiring of a VAZ?

Hello, very good site, a lot is clear. My question is this. Or, more simply, did I go wrong? I became, so to speak, a victim of outbids. The story is like this. Based on many conversations and reviews when buying a car, everyone (friends, friends) said that they were the best cars in the area, which is what I did. I was going with my girlfriend to the city of Magnitogorsk from the city of Chelyabinsk to buy a car in the region of 83 thousand rubles. Of course, I expected bad things from this car for that amount, but nothing stopped me. Having visited all the markets there, and there are only two of them, the left bank and the right bank, and called all the sellers (direct owners), the choice fell on the VAZ 2110 1.5L. 8kl. (injector) 1998, the color according to the title is green (it looks like a tsunami or something else), in general it’s painted, well, everything is beautifully polished as always, I got under the bottom, it’s not rotten, I looked at the sills, they’re not rotten, the anthers have been changed (or rather, as it turns out, they’ve been rubbed with shoe polish ), but the most interesting thing awaited me 156 km from Chelyabinsk (two blows under the hood, white smoke from the clutch side), I dialed his phone in shock, saying that he is inhumane, etc. but he claims that everything worked, it’s my own fault. I called my friends and got me to Chelyabinsk, so I parked the car in the garage. Then I had to look for a new working cylinder block assembly (that block was hastily sealed, the antifreeze was combined with oil), my friend and I spent a week together. The cylinder block cost me 11,200 rubles. replacement of consumables: Shel oil 1400 RUR oil in G-box 1350 RUR armor wires elephant 400 RUR Bosch spark plugs 430 RUR air filter 150 RUR oil filter 130 RUR fuel filter 115 RUR antifreeze Felik 10L 700 RUR
