The UAZ Patriot SUV has gained wide popularity among the population of the Russian Federation and not only. After all, the main purpose of the UAZ Patriot SUV is to overcome various kinds of obstacles and operate not only on roads, but also off-road. In connection with such indicators, this car must be reliable, comfortable and have excellent technical parameters. Today we will pay attention to the electrical part of the SUV, on which not only the movement of the vehicle actually depends, but also its start.
Characteristic
The electrical circuit of the off-road vehicle is based on the single-wire principle. The positive terminal from the battery is connected to each electrical consumer, and the negative terminal from the battery is screwed to the car body. After turning on the ignition, power is supplied only to the main consumers. All other electrical consumers are powered by the battery directly through the power button.
The electrical equipment of the SUV complies with the Euro-3 standard, and the electrical circuit is equipped with fuses and relays located in the mounting block. For the Ulyanovsk Patriot, the mounting block is mainly manufactured in Slovenia. The peculiarity of such a block from abroad is based on the fact that it cannot be repaired, since it is non-separable. Therefore, the designers of the Ulyanovsk plant since 2012 began to complete their creations with collapsible mounting blocks.
Helpful information! Since 2012, the production of diesel engines for the UAZ Patriot SUV has been launched at the Ulyanovsk Automobile Plant. Thus, in 2012, the first SUV of the Patriot model with a turbodiesel engine rolled off the assembly line of the plant. According to environmental standards, and electrical wiring standards, this engine complied with the Euro-4 class, which is still a big plus.
Since 2012, the UAZ Patriot SUV has also been equipped with a useful option called the Winter Package. This package includes the following useful emails. features:
- heated windshield;
- additional e-mail a stove with which the rear of the cabin is heated;
- heated rear seats.
This addition made it possible to make the UAZ Patriot SUV even more comfortable and popular.

Wiring
Email wiring cables are bundles that branch out from the mounting blocks and go directly to the equipment. Mandatory elements of the electrical circuit of the car are fuses that perform a protective function.
If a breakdown occurs in the mounting block, then domestic models of this product are subject to repair. To do this, you need to disassemble the unit and find the problem. Often the malfunction is the burning of the tracks on the printed circuit board. To understand the principle of building a printed circuit board, you need an electrical circuit. Such a scheme is shown in the photo.
Wiring plays an important role by closing the DC circuit, thereby providing power to each email. car instrument.
The wiring diagram for the equipment of the UAZ Patriot off-road vehicle from 2007 onwards.
Since 2007, domestic SUV manufacturers have come to a consensus on the need to switch from the Euro-2 environmental standard to Euro-3 for gasoline engines. As a result of the transition from one standard to another in 2007, the electrical circuit received some modifications. Such email. The circuit is shown in the figure above, which is a fuel injection system. The Patriot wiring diagram from the year 2007 differs from the circuit of an earlier car production in that the injection system control unit was absent in the system.

UAZ Patriot is a very popular Russian car in its class. Given that its operation is associated with the maximum permissible climatic and landscape conditions, there are cases of electrical equipment failure.
The most common causes of failure of the electrical part of the car:
- mechanical damage to the wiring (open circuit, short circuit, terminal wear, etc.);
- failure of sensors and assemblies due to moisture ingress, corrosion processes;
- malfunction of control units and control units;
- failure of lighting equipment, fuses, relays;
- failures in the operation of electronic units;
- problems in the operation of the starter, generator, corrosion of the battery terminals.
The UAZ Patriot model range includes cars with engines made according to Euro 2 (until 2007), Euro 3 (release from 2007 to 2017) and Euro 4 (after 2013) standards.
The electrical equipment diagram of the UAZ Patriot for each modification has its own characteristics associated with the design of the engine control system, the use of various electronic units and other equipment. So, cars until 2012 were equipped with Slovenian mounting blocks for relays and fuses. They have a non-separable design, and theoretically cannot be repaired if they have an internal malfunction (melted conductors, broken contacts, etc.). In practice, such problems are also solved, but only by experienced craftsmen and using original methods. Since 2012, Patriot cars have been equipped with a collapsible mounting block for relays and fuses (similar to VAZ), which greatly simplifies the process of repairing this unit.
Turbodiesel engines of UAZ Patriot cars, which have been installed in production cars since 2012, comply with the Euro 4 standard. Meeting high environmental requirements required complicating the circuitry solutions of the car's electrical equipment.
The composition of the additional equipment of cars includes a "winter package", which includes the following electrical equipment:
- electric heating of the windshield;
- additional electric interior heater;
- heated rear seats;
- high capacity battery.
In order to carry out prompt and high-quality repairs of the electrical equipment of a car, it is necessary to carefully study the circuit diagram corresponding to the year of manufacture of the car.
Wiring diagram UAZ Patriot until 2007 release
The circuit diagram is shown in Fig. 1
The conductors of the electrical circuit connections are made of stranded copper wire enclosed in polyvinyl chloride (PVC) insulation with one- or two-color marking in accordance with the electrical circuit. Groups of conductors are combined into electrical bundles. A common cause of wiring failure is shorted wires inside the harness due to a short circuit. In this case, it is necessary to “gut” the entire tourniquet to make sure that there are no internal melting and short circuits along its entire length. In the event of a violation of the electrical connections between the nodes of the electrical circuit, it is necessary to “ring out” the connections from a specific executive element to the node control unit in accordance with the above diagram.
The designation of the circuit elements is shown in Fig. 2
The designation of the elements is shown in Fig. 4
In the event of a failure of the electrical equipment, you should first check the serviceability of the relays and fuses in accordance with the diagram in Fig. 5:
When replacing failed fuses, first of all, you should make sure that there are no short circuits in the wiring, that the device it serves is in good condition, then install the fuse in exact accordance with the rating (current) indicated on the fuse box. One fuse can serve several electrical components, you should make sure that all elements are in good condition.

The wiring diagram of the UAZ Patriot with the YaMZ-409 Limited engine (Fig. 6) is much more complicated than previous models. When repairing vehicles of this generation, special manuals must be used.
Car diagrams. How to read them?
This category will provide information about the electrical connections in the UAZ Patriot car (about wiring diagrams).
The wiring diagram of the UAZ Patriot has minor differences for models before 2007 and after. Here you can find both one and the other option. Also, depending on the engine and its environmental class EURO 2 or EURO 3, various wiring diagrams for connection are implemented. The category will provide an electrical connection diagram for the mounting block, which is located on the left side in the cabin under the instrument panel.
As in all cars, so in the UAZ Patriot, most electrical circuits are protected by fuses and controlled through power relays. Such a classic solution allows avoiding overloads for electrical wiring in the car, as well as dividing all circuits into control and power ones. If a fuse blows in the circuit, then one or more of the functions on the machine stop working. In order to correct the situation, it is necessary to replace the fuse.
The mounting electrical unit on the UAZ Patriot car performs the function of communicating most of the car's electrical circuits. It also contains control relays and fuses.
The mounting electrical unit is removed from the machine in case of its repair, replacement, or when removing the instrument panel. In this article we will talk about its dismantling.
On UAZ Patriot vehicles, an oxygen concentration sensor is installed, which determines the amount of oxygen in the exhaust gases. In fact, a determination is made whether the mixture was "poor" or "rich". After measuring the amount of oxygen, the duration of the ignition pulses is adjusted, which allows you to burn the fuel most efficiently.
The operation of the sensor is manifested by the generation of a low-voltage signal from 0.1 to 0.9 volts, which is fed to the machine's ECU, and then the ignition is corrected from there. The voltage at the sensor rises as the oxygen in the exhaust gases decreases. A feature of the sensor is that it only works at temperatures above 300 degrees Celsius. As a result, a heating element is installed in the sensor, which ensures its heating in the first minutes, until the exhaust manifold has warmed up.
On UAZ Patriot vehicles, a knock sensor is installed. The sensor is a piezoelectric crystal that generates minor electrical impulses from mechanical impact on it, which are engine knocks.
As a result, when such detonations occur and voltage appears on the sensor, the ECU makes adjustments for the ignition pulses in the working cylinders of the engine in order to reduce this very detonation. Typically, such detonation is characteristic of low fuel quality, or when the engine is overloaded. When the sensor fails, the ECU sets the ignition to “late”, which affects engine power and fuel consumption, not for the better. Therefore, the knock sensor must be replaced as soon as possible.
Three knock sensors can be installed on the machine:
The throttle position sensor determines the location of the damper in the throttle assembly, which passes the air flow involved in the formation of the fuel-air mixture. Depending on the position of the damper, and hence the sensor, the resistance between the main contact and the contact on the slider, which walks along the turns of the wire, changes. Based on the change in this resistance, the UAZ Patriot ECU determines the position of the damper and adjusts the fuel injection according to the air supply. The sensor shaft travel is 100 degrees. If the sensor malfunctions, the engine may exhibit uneven idling or dips during uniform movement.
The air mass flow sensor determines the volume of air passed through itself, as well as its temperature, which allows you to calculate the exact amount of air involved in creating the fuel-air mixture.
In case of failure of the air flow sensor, the controller takes the average value of the flow rate, and the air temperature takes a fixed value of 33 degrees Celsius.
The principle of operation of the sensor is based on a change in internal resistance, due to the thermistor installed in it. The dependence of the internal resistance of the sensor on temperature is summarized in the table below ...
The sensor is installed on the intake manifold between the air filter hose and the intake pipe hose.
On a UAZ Patriot car, a camshaft position sensor is installed, or it is also called a phase sensor. Based on information from the phase sensor, the controller (ECU) determines the moment when the piston of the 1st cylinder is set to TDC and uses this data for fuel injection cycles according to the operation of the cylinders.
We can say that it is similar to the crankshaft position sensor, but mounted on the camshaft.
On the UAZ Patriot car, a crankshaft position sensor is installed, which determines the TDC position for the first cylinder of the engine.
The definition of such cyclicity is necessary for the power supply and ignition system. The crankshaft position sensor is the only sensor, if it fails, you will not be able to start the car engine.
On a UAZ Patriot car, a sensor of the type DG-6 0261210113 from Bosch or 23.3847 can be installed. Both sensors are made in the form of an inductor with a core, which reacts to a change in the magnetic field around it. The change in the magnetic field occurs due to the rotation of the synchronization disk with the teeth on it.
