Black and white wiring diagram UAZ patriot. What are the main aspects of troubleshooting wiring for the UAZ Patriot wiring diagram? Photo gallery "Main malfunctions"

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 show circuit diagram connection 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 avoids overloads for electrical wiring in the car, and also divide all circuits into control and power. 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 small 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:

Position sensor throttle valve 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 operation on Idling or dips in uniform motion.

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 intake manifold between the hose air filter and inlet hose.

A position sensor is installed on a UAZ Patriot car camshaft or else it is referred to as 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 position sensor crankshaft 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.

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 these 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 movement actually depends vehicle, but also its start.

Characteristic

Scheme electrical equipment SUV is based on a single-wire principle. 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.

Useful information! Since 2012 at Ulyanovsk car factory, production was launched diesel engines for SUV UAZ Patriot. 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 corresponded to 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:

• heating 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.

The wiring diagram for the equipment of the UAZ Patriot SUV until 2007.

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 there is a breakdown in the mounting block, then domestic models this product is repairable. 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 in completing the circuit direct current, 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 injection system fuel injection. 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.

The Patriot is made mainly in a single-wire circuit. The negative outputs of the consumers are connected to the car body and engine, which act as a second wire. The nominal voltage in the on-board network of the car is 12 volts. Electrical diagrams of the UAZ-3163 Patriot of different years of production are presented below.

Wiring diagrams UAZ-3163 Patriot with a ZMZ-409 engine manufactured in 2005, 2007, 2013, 2014.

Switches for outdoor lighting and fog light, the switch for operating modes of the electric fan are located on the console under the instrument panel. The switches for headlights, direction indicators, wiper and washer are combined into a steering column switch block. Electrical consumers of high power are switched on through electromagnetic relays.

The electrical circuits of the engine management system are made according to a multi-wire circuit and are connected to the vehicle ground only through the electronic unit management. To switch the main circuits of the car, a combined ignition switch is used, consisting of a contact part and a mechanical anti-theft device with a lock.

Features of the operation of electrical equipment UAZ Patriot.

Any work on electrical equipment should only be carried out with the battery disconnected.
- Disconnect or connect the battery only when the ignition is off.

When checking the circuits of electrical equipment, it is forbidden to short the wires to ground, check the serviceability of the circuits "for a spark", as this can lead to failure of electrical equipment elements.

It is forbidden to use fuses not provided for by the vehicle design or designed for a higher current, and wire instead of fuses.

When replacing fuses, it is forbidden to use metal tools, this can lead to a short circuit in the circuits of electrical equipment.

It is forbidden to disconnect the battery while the engine is running in order to avoid failure of the voltage regulator and elements electronic system engine control.

To exclude failure of the diodes of the rectifier unit, it is forbidden to check them on the car with a megger or test lamp, with a supply voltage of more than 12 volts, without disconnecting the wires from the generator.

It is possible to check the insulation resistance of the generator stator winding with increased voltage only on the generator removed from the vehicle, with the stator winding terminals disconnected from the rectifier unit.

When carrying out electric welding work directly on the car, it is necessary to disconnect the wires from the terminals battery, generator outputs and engine control unit.
- It is not advisable to lay low voltage wires in the same bundle with high voltage wires.

When recharging the battery using a separate remote device directly on the vehicle, be sure to disconnect the wires from both battery terminals.

One of the features modern cars Russian production is the presence of a large number of various devices and systems that provide more comfortable operation of machines. UAZ Patriot cars are no exception. What elements does the UAZ Patriot electrical circuit include and how to identify electrical problems? We will talk about this below.

Peculiarities

The electrical equipment diagram of the UAZ Patriot consists of many components, its main systems are:

• injection and ignition, including candles, distribution unit, starter;
• generator set and storage battery;
• motor control device;
• control panel on which sensors and diode indicators are installed;
• steering;
• power windows, if any;
• optics;
• interior lighting, and rear number auto;
• an audio system that includes a radio, speakers, as well as an amplifier and a subwoofer, if any;
• rear window heating unit;
• heating system;
• mounting block with safety elements.

How to determine the malfunction?

How to determine the presence of voltage in the wiring of a car:

1. To check, you need a control light, you need to solder two wires to it. One tester probe must be connected to the negative terminal of the battery or the car body, and the second to the tested section of the electrical circuit. In order to more accurately determine the absence of voltage, it is advisable to connect the second probe as close as possible to the battery or fuse.
2. If, as a result of the connection, the control one lights up, this may indicate that there is voltage on the one under test.
3. In the same way, you need to check other components of the electrical network. If it happens that the light source does not light up, then the cause of the malfunction must be sought in the area between the point being tested and the last place where the voltage was. Usually, wiring malfunctions are associated with poor contact, so you should diagnose the quality of the connection. In addition, depending on the section of the circuit being checked, there can be voltage on it only when the key is turned in the lock (the author of the video is Dmitry Sherstnev).

If you have any suspicions about the unreliability of grounding, then the test can be performed as follows:

1. First of all, the ignition is turned off and the terminals are disconnected from the battery. Then, using the same control light, one of its probes should be connected to the Patriot body.
2. The second pin from the tester is connected to the ground point, in particular, we are talking about the area that you are testing.
3. If after connecting the light turns on, then this indicates that everything is in order with grounding. Accordingly, you can start checking other areas.

One of the problems that occur in the wiring is a violation of the integrity, that is, a break or damage to the cable.

To diagnose this problem, do the following:

1. First of all, the voltage is disconnected from the electrical circuit, for this, the terminals are disconnected from the battery. Checking the continuity of the circuit is carried out using a test light, as well as a connected power source.
2. Then one probe from the testing device must be connected to the positive end of the circuit under test, the second to ground, that is, the car body. Or two probes from a light bulb are connected to both ends of the area being diagnosed. If the lamp lights up as a result of the connection, this indicates that the circuit is intact and there is no damage in it. Accordingly, if the light does not light up, then the area is damaged.
3. The switch is also diagnosed, the tester probes must be connected to the terminals of the device. When the switch is turned on, the lamp should light up.

Possible wiring problems

Troubleshooting electrical system can be divided into several types:

1. Malfunctions of the electrical equipment itself.
2. Failure of the safety element. Fuses blow due to natural wear or as a result of voltage drops in the system. If you encounter such a problem, when the same fuse often fails, this may indicate that there is a drop in this section of the circuit. The jump can be due to various reasons, but as a rule, the problem lies in the use of more powerful equipment. For example, if you plug in a tee, while powering all three sockets of the device, this can lead to a serious jump. Before replacing a fuse, make sure that there are no surges in the system.
3. Poor contact of the electrical circuit with the equipment. In this case, there may be several reasons. First, you need to check the integrity of the wiring, you already know how to do this. Secondly, it is necessary to check the connection contact itself - there is a possibility that the reason lies in a bad connection, perhaps the contacts need to be changed or cleaned.
4. Not so often, Patriot car owners are faced with the problem of current leakage, which, in turn, is usually caused by breakdowns in the electrical circuit. Using a tester or a light bulb, you can determine the failed defective area and replace the damaged cable. If the damage is minor, then several layers of electrical tape can be wound on the cable.
5. Failure of the generator unit. To determine the malfunctions in the operation of the generator, it is necessary to remove and disassemble the mechanism in order to identify damaged components.
6. Sometimes car owners are faced with the problem of the inability to start the engine due to a discharged battery. There may be several reasons for the discharge, therefore, in addition to measuring the voltage, you must also visually inspect the device case and the presence of electrolyte in it. If there is too little liquid in the jars, then its level must be replenished with distillate.

UAZ Patriot - very popular in its class Russian car. 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.

IN model range UAZ Patriot presents 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 circuit 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 components 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 relays and fuses (similar to VAZ), which greatly simplifies the process of repairing this unit.
Turbodiesel engines of UAZ Patriot cars, which began to be installed on stock cars since 2012, they comply with the Euro 4 standard. Meeting the high requirements of environmental friendliness required the complication of circuit solutions for electrical equipment of cars.
Part additional equipment cars are included in the "winter package", which includes the following electrical equipment:

• electric heating of the windshield;
• additional electric interior heater;
• heated rear seats;
• high capacity battery.

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 connections of the electrical circuit 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. Common cause wiring failure - the short circuit of the wires inside the bundle 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, 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.
