How to determine a malfunction?

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

1. To check, you will need a check light, two wires need to be soldered to it. One tester probe must be connected to the negative conclusion 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, the second probe is desirable to connect as close as possible to the battery or the fuse.
2. If the control caught fire as a result of the connection, this may indicate that there is a voltage on the checked.
3. In the same way, you need to check other components of the power grid. If it happens that the lighting source does not light up, then the reason for the malfunction should be signed on the site between the test point and last placewhere the voltage was. Usually faults in the work of the wiring are associated with poor contact, so the connection quality should be diagnosed. In addition, depending on the checked section of the chain, the voltage on it can only be when the key is turned in the lock (the author of Dmitry Sherstnev).

If you have suspicions regarding the unreliability of grounding, then the check can be performed like this:

1. First of all, the ignition is turned off and the terminals from the battery are disconnected. Then, using the same control light, one of its probe should be connected to the body of the patriot.
2. The second contact from the tester is connected to the grounding point, in particular, we are talking about the site that you check.
3. If after connecting the bulb caught fire, then this suggests that everything is in order with the ground. Accordingly, you can proceed to check other sections.

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

To diagnose this problem you need to do the following:

1. First of all, the voltage is disconnected from electrocups, for this, the terminals are disconnected from the battery. Checking the integrity of the chain is carried out using a control 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 checked chain, the second to the mass, that is, the car body. Or two probe from the light bulb are connected to both ends of the diagnosed area. If a lamp will turn around as a result of the connection, this suggests that there is no chain and damage in it. Accordingly, if the light is not caught fire, the site is damaged.
3. The diagnostics of the switch is also carried out, the tester probe must be connected to the device outputs. When the switch is turned on, the lamp should turn around.

Possible wiring problems

Problems in work electrical system You can specifically divide into several types:

1. Faults of electrical equipment.
2. The failure of the safety element. The fuses are braked due to natural wear or as a result of voltage drops in the system. If you encountered such a problem when the same fuse often fails, this may indicate that there is a differential in this section of the chain. The jump may be due to different reasons, but as a rule, the problem lies in the use of more powerful equipment. For example, if you connect the tee, with all the three device jacks, it can lead to a serious jump. Before replacing the fuse, make sure that there are no jumps in the system.
3. Bad electrocuprup contact with equipment. In this case, the reasons may be several. First, you need to check the integrity of the wiring, how to do it, you already know. Secondly, it is necessary to check the connection itself - there is a chance that the reason lies in a bad connection, it is possible that contacts need to be changed or cleared.
4. Not so often, the car owners of patriots face the problem of current leakage, which, in turn, is usually due to breakdowns in electrocups. With the help of a tester or light bulb, you can determine the failed defective area and replace the damaged cable. If the damage is insignificant, then several layers of tape can be coated on the cable.
5. The failure of the generator node. To determine the operation of the generator, you need to remove and disassemble the mechanism to identify damaged components.
6. Sometimes car owners face the problem of the impossibility of starting the engine due to the discharged battery. The reasons for the discharge may be somewhat, so besides measurement of the voltage, it is also necessary to visually inspect the device's body and the presence of electrolyte in it. If the liquids in the banks are too small, then its level must be fill with the help of a distillate.

UAZ Patriot - very popular in its class russian car. Given that its operation is associated with extremely permissible climatic and landscaped conditions, there are cases of malfunction of electrical equipment.

The most frequent causes of the electric part of the car are:

• mechanical damage to the electrical wiring (circuit break, closure, terminals and other);
• failure of sensors and nodes due to moisture, corrosion processes;
• malfunction of control nodes and control blocks;
• failure of lighting equipment, fuses, relays;
• failures in electronic blocks;
• problems in the work of the starter, the generator, corrosion of the terminals rechargeable battery.

IN model row UAZ Patriot are represented by cars with engines made according to Euro 2 standards (until 2007), Euro 3 (release from 2007 to 2017) and Euro 4 (after 2013).
The electrical equipment of the UAZ patriot for each modification has its own characteristics associated with the engine of the engine control system, using various electronic blocks and other equipment. So, cars up to 2012 released by Slovenian mounting blocks of relays and fuses. They have an inappropriate design, and are not theoretically to be repaired if they have an internal malfunction (melted conductors, destroyed contacts, etc.) almost such problems are also solved, but only experienced masters and using original methods. Since 2012, patriot cars are completed with the collapsible assembly block of relay and fuses (similar to the VAZ), which significantly simplifies the repair process of this node.
Turbodiel engines of the UAZ Patriot cars, which began to install on serial cars since 2012, comply with the Euro standard 4. The fulfillment of high demands of environmentally friendly demanded complications of the circuitry solutions of electrical equipment of cars.
Part additional equipment Car includes "Winter Package", which includes the following electrical equipment:

• electrically heated windshield;
• an additional electric salon heater;
• heated seats rear row;
• high Capacity Battery.

To carry out the operational and high-quality repair of the electrical equipment of the car, it is necessary to carefully examine the fundamental electrical scheme corresponding to the year of the car.

Electrical scheme UAZ Patriot until 2007 release

Principal electrical circuit depicted in Fig.1

The conductors of the electrical circuit compounds are made of their stranded copper wire enclosed in polychlorvinyl (PVC) insulation with one or two-color marking in accordance with the electrical circuit. Groups of conductors are combined into electric harnesses. Frequent cause of electrical wiring failure - closure of wires inside the harness due to a short circuit. In this case, it is necessary to "jump out" the whole harness to make sure that there are no internal mesh and closures throughout its entire. In case of disruption of electrical connections between electrical circuits nodes, it is necessary to "ring" communication from a particular executive element to the control unit of the node in accordance with the shown scheme.
Designation of the elements of the scheme is shown in Fig. 2

The designation of the elements is shown in Fig.4.

Electrical scheme UAZ Patriot since 2012 release

Electroshem UAZ Patriot with the engine of the YAMZ-409 Limited (Fig. 6) is much more complicated than previous models. When repairing this generation cars, you need to use special manuals.

Car diagrams. How to read them?

The Russian SUV patriot is the flagship of domestic automotive industry. It is quite reliable, comfortable and has excellent specifications.

Electrical equipment car

Domestic SUV.

It has 5 doors that are located in the all-metal body. The serial release of the machine began in August 2005 in the city of Ulyanovsk. Four-wheel drive and high clearance allow you to operate a car on the roads with a bad coating.

Electrical equipment UAZ patriot is performed on a single-wire diagram. The output of each electromotor is connected to the "plus" of the battery, the second wire is fed to the "mass". Through it, there is a connection with the "minus" of the rechargeable battery. The ignition key includes only the main UAZ Electroschem. Electropoters such as cigarette lighter, sound signal And the ceiling, turn on without the ignition lock. They are connected directly.

Integrated car electrical equipment complies with EURO-3 standard and protected by fuses installed in the mounting unit. The mounting unit of electrical equipment can be both domestic and manufactured in Slovenia.

Imported electrical equipment UAZ Patriot is inferior to the domestic in the sense that it is inseparable and cannot be repaired. In case of failure, some detail has to change the entire fee. In addition, imported components are used in the manufacture of the machine.

1. Italian power steering.
2. German brake systems.
3. Conditioners of English production.
4. Korean seats.

Since the beginning of 2012, the production of a car with a domestic turbo diesel engine has been established. His environmental Safety corresponds to the Euro-4 class. The car added a new option "Winter Package". It includes heating rear seats, Heated front glass, separate stove for heating rear passengers.

Location of electrical wiring

All electrical wiring of the car is made in the form of cable harnesses, which diverge from the mounting unit to the corresponding nodes. Connection of wires with auxiliary relay, dashboard and other elements of electrical equipment occurs through the fuse block. Domestic mounting blocks can understand. Due to this scheme of electrical equipment UAZ can be easily restored after breakage. To do this, it will be enough to identify the burnt item in pCB And replace it.

Electronics Auto

In order for the driver to understand the principles of electrical equipment, in technical description Machines have detailed drawings and a description of the work of the most important nodes and mechanisms. If the electrical circuit in some board has damage to the current track, in this place is allowed to buy a slim wire. In this case, the fault will be eliminated almost without any material costs. Detailed schemes make it possible to present the principle of electrical equipment. In this case, the UAZ scheme has the following form: Fig.1.

During maintenance Car Checked Coolant Level, Lubrication System, Quantity brake fluid In the brake cylinder tank and tire pressure.

In this category, information on electrical connections in the UAZ Patriot car will be provided (about electrical stamps).
Electroshem UAZ Patriot has minor differences for models until 2007 and after. Here you can find both the same and the other option. Also, depending on the engine and the class of its ecology Euro 2 or Euro 3, various electrical circuits for connecting are implemented. The category will show an electrical connection diagram for the mounting unit, which is located on the left side in the cabin under the instrument panel.

As in all cars and in UAZ Patriot, most electrical chains are protected by fuses and are controlled through power relays. Such a classic solution allows you to avoid overloads for electrical wiring in the machine, as well as divide all chains to control and power. If the fuse burns in the circuit, then one or more of the functions stops on the machine. In order to correct the situation, it is necessary to replace the fuse.

Mounting electric block By car UAZ Patriot performs the function of communicating most of the car's electrical circuits. It also has control relays and fuses.
The mounting electric unit is removed from the machine in the event of its repair, replacement, or when removing the instrument panel. In this article we will talk about his dismantling.

On oz Patriot vehicles, the oxygen concentration sensor is established, which determines the amount of oxygen in the exhaust gases. In fact, the definition occurs whether the mixture was "poor" or "rich". After measuring the amount of oxygen, the ignition pulse duration is adjusted, which allows to burn fuel most effectively.
The sensor operation is manifested by the generation of low-voltage signal from 0.1 to 0.9 volts, which enters the machine of the machine, and then the ignition is adjusted from there. The voltage on the sensor increases when the oxygen decreases in exhaust gases. The feature of the sensor is that it works only at a temperature of more than 300 degrees Celsius. As a result, the heating element is installed in the sensor, which ensures it in the first minutes until the exhaust manifold warmed up.

On vehicles UAZ Patriot installed detonation sensor. The sensor is a piezoelectric crystal, which forms minor electrical impulses from mechanical impact on it, which are the detonation of the engine.
As a result, when there are such detonations and the appearance of voltage on the sensor, the ECU produces an adjustment for the ignition pulses in the engine working cylinders in order to reduce this very detonation. Usually, such detonation is characteristic of low fuel quality, or when engine overloads. When the sensor is output, the ECU sets the ignition to the "later", which affects the engine power and fuel consumption, not for the better. Therefore, at the first opportunity, the detonation sensor must be replaced.
Three detonation sensors can be installed on the machine:

Position sensor throttle valve Determines the bazing of the flap in the throttle node, which passes the air flow involved in the formation of the fuel and air mixture. Depending on the position of the damper, which means the sensor, the resistance varies between the main contact and contact on the runner, which goes through the coils of the wire. Based on the change in this resistance, the UAZ Patriot determines the position of the flap and adjusts the fuel injection, according to air supply. Sensor shaft running leaves 100 degrees. When the sensor malfunction is possible, the engine unevenness is possible on idling Or failures with uniform movement.

Sensor mass flow The air determines the volume of transmitted air through itself, as well as its temperature, which allows calculating the exact amount of air involved in the creation of the fuel and air mixture.
In case of failure of the air flow sensor, the controller takes the average value by consumption, and the air temperature takes a fixed - 33 degrees Celsius.
The principle of operation of the sensor is based on changing internal resistance, due to the thermistor installed in it. The dependence of the internal resistance of the sensor from temperature is reduced to the table below ...
The sensor is installed on the intake manifold between the hose air filter and hose inlet tube.

On the UAZ Patriot car, the camshaft position sensor is installed or it is also called a phase sensor. Based on the information from the phase sensor, the controller (ECU) determines the moment of the installation of the 1st cylinder piston in the NTT and uses this data for fuel injection cycles according to the operation of the cylinders.
It can be said that it is similar to the crankshaft position sensor, but installed on a camshaft.

On the UAZ Patriot car, the crankshaft position sensor is installed, which is determined by the NMT position for the first cylinder of the engine.
The determination of such cycles is necessary for the system of nutrition and ignition. The crankshaft position sensor is a single sensor, when the car engine is faulty, you cannot run.
On the UAZ Patriot car can be set to the DG-6 0261210113 sensor of the company Bosch or 23.3847. The other sensor is made in the form of an inductance coil with a core that reacts to changing the magnetic field around it. The change in the magnetic field is due to the rotation of the synchronization disk with the teeth on it.
