Features of the operation of the mounting block and the relay and fuse block.
Before replacing a blown fuse, you must first find out the cause of its blown out and eliminate it. When troubleshooting, it is recommended to look at the circuits that this fuse protects. When removing relays and fuses, do not use metal objects.
When replacing fuses and checking the electrical circuits of the car, it is not allowed to use fuses that are not provided for by the design, as well as short-circuit the wires to ground, check the serviceability of the circuits "for a spark", as this can lead to burnout of the current-carrying buses of the mounting block or relay and fuse block.
Repair of the mounting block and the relay and fuse block consists in replacing the failed relays and fuses. Soldering of wires is allowed instead of burnt out busbars.
It is not at all surprising that such a domestic SUV as the UAZ Patriot is very popular. The Ural manufacturer "rewarded" this vehicle with unique power and high cross-country ability. Making a trip on such a car, you can be sure of absolute safety, since it is no secret that this car is characterized by a high level of reliability. However, this does not mean at all that the owner of the car will not experience any problems throughout the entire operational period. Over time, parts wear out, many devices fail, while remaining completely indifferent to the fate of your "iron friend" is impossible, since one technical failure will provoke another technical failure.
There are situations when the owner of the UAZ Patriot discovers a problem related to the heating of the passenger compartment. Trying to start the stove, the owner chooses different ones, however, all attempts are unsuccessful, since the stove continues to "persist". If such a situation arises, it is important to figure out whether the heater is completely "dead" or it is working, but it sends only cold air to the passenger compartment. The further plan of action will depend on the result of your observations.
Replacement process
If, when performing any actions, the stove continues to be inoperative, then you should suspect a power failure and the following technical problems. Indeed, any surge in the power grid is dangerous for the installed equipment. For this reason, in order to prevent damage to them, the manufacturer equips any vehicle with some elements that perform protective functions.
These elements include fuses, their number installed in a vehicle is far from being a single one. Each fuse is responsible for the operation and safety of individual devices and mechanisms. They are located in the mounting block. It is not difficult to find it in the UAZ Patriot. Move into the passenger compartment, bend over in the driver's seat area and pay attention to the space under the dashboard on the left side. The fuses are in a sealed box. To directly penetrate to them, it is enough to clamp two latches, and then pull the cover towards you. You can find it based on the layout of the elements provided by the manufacturer. In this case, it is enough to pay attention to the elements responsible for the device that stopped working. If you do not have such a circuit at hand, then you will have to remove each fuse one by one and visually inspect its contacts. It will take a while, but you can still find a damaged fuse.
Sometimes there may be other troubles associated with heating the passenger compartment. In particular, the owner of the UAZ Patriot is making efforts to change the fan operating mode, but all these attempts are unsuccessful. The fan works, but only when the fourth speed is selected. In this case, counting on high-quality heating is also useless. The experts point out that these "symptoms" indicate that they are not to blame for such a technical failure. The main culprit is the failed resistor. It is not recommended to repair it, it is useful to purchase a new element and install it, having previously eliminated the useless one. It should be noted that the resistor rarely breaks down, more often it breaks down due to burning of the contacts. It is not difficult to find where the resistors on the UAZ Patriot car can stand. Again, you will have to go into the salon, bend over and turn your gaze to the space located above the gas pedal. The process of replacing the resistor is not complicated, since no additional devices need to be removed.
Also, it does not interfere at all with understanding, on a UAZ Patriot car, if the heater starts to work only when the engine warms up well enough. Finding the relay is also easy, since you only need to shift your gaze to the center console, which is embedded just below the dashboard. We recommend that you do not strive to repair the relay, but rather save your own nerves and purchase a new element. Repair measures will still not lead to positive changes, thanks to which the successful operation of the heater will be able to resume.
So, take your time to the service station if you suddenly notice that. Many problems can be easily solved if you first arm yourself with the necessary information. For this reason, we recommend that you study the recommendations of the masters and, rolling up your sleeves, independently remove the detected damaged element, purchase a new analogue and install it. The result of the work will delight you when the interior of your favorite car is quickly filled with streams of warm air. You will be especially pleased that you do not need to spend your hard-earned savings on paying for the services of craftsmen.
Fuses are used to protect sections of the electrical circuit against overloads and short circuits. And often, to eliminate the malfunction, it is enough to change the fuse link. The main thing is to know where they are.
The engine control unit
The electrical diagram of the engine control unit for the UAZ Patriot release since 2012 is shown in Fig. 1. It is made in accordance with the Euro 4 standard. Some cars use a slightly modified circuit with four ignition coils.
The decoding of the block elements is given in the table in Fig. 2
The above factory specification of assemblies uses somewhat unfamiliar military-industrial terminology. For example, the crankshaft sensor is called the timing sensor, the camshaft sensor is called the phase sensor, and the idle speed control is called the auxiliary air regulator. The essence of the functions performed does not change from this.
A very useful addition is the presence of a standard OBDII connector for carrying out diagnostic work. Not all universal diagnostic scanners can fully read UAZ Patriot errors, but any simple autoscanner can diagnose engine errors in OBDII mode.
The pinout (location and numbering of pins) of the control unit looks like Fig. 3:
The most problematic units of the UAZ Patriot engine control system, as in other cars, are:
- ignition coils;
- idle speed regulator;
- synchronization sensor;
- gasoline pump.
Taking into account the harsh operating conditions of the car, it is necessary to timely (preferably with a doubled frequency) perform routine maintenance related to the operation of these units, namely:
- clean the spark plugs and zones of high-voltage ignition signals, including the housing of the ignition coils, to reduce the likelihood of breakdown;
- clean the throttle valve area of dust, regularly change the air filter;
- make sure that dust and dirt do not get into the gas tank, once a year, clean it from settled dirt and impurities;
- clean the electrical wiring from dirt, dust, oil leaks.
The wiring diagram of the ABS / ESP unit of the UAZ Patriot release since 2012 is shown in Fig. 4
On slippery road surfaces, the ABS and ESP unit significantly increases the stability of the vehicle, hence driving safety. The most common cause of failure of the ABS system is a break in the wiring connection to the wheel sensors (FL front left - front left, FR - front right, RL and RR - front left and front right, respectively). In this case, they must be “ringed” with a multimeter to the ABS unit in accordance with the diagram.
Fuse blocks
Any electrical repair usually begins with checking the fuses and control relays.
The passenger compartment relay fuse box is located below the dashboard under the cover. To gain access, you must press the latches, releasing the cover from the hooks.
The layout of the cabin fuses and relays is shown in Fig. 5
The designation of the relay is shown in Fig. 6:
The purpose of the fuses is shown in the table in Fig. 7
It should be noted that some modifications have a slightly modified fuse sequence; for clarification, you should be guided by the vehicle operating instructions.
View of the fuse box located in the engine compartment Fig. 8
It is located behind the battery Fig. 9
The decoding of relays and fuses is given in the table in Fig. 10 and 11
Usually, if problems arise with starting the car, the first step is to start checking the relays and fuses located in the engine compartment. In the event that there is a suspicion of a malfunction of any relay, you can temporarily swap places with a similar one from an adjacent socket, if any.
It is imperative to check the serviceability of the fuses by removing them from the socket using two methods: visual and using a multimeter (dial tone).
As in all cars, so in the UAZ Patriot, most of the electrical circuits are protected by fuses and controlled through power relays. This classic solution allows you to avoid overloads for electrical wiring in the car, as well as to divide all circuits into control and power. If a fuse blows out in the circuit, then one or more of the functions on the machine stops working. In order to remedy the situation, it is necessary to replace the fuse.
Before we talk in more detail about the fuses and relays installed on the UAZ Patroit, we will give general information about the generally accepted colors and ratings of fuses for current, in accordance with them.
The machine is fitted with a fuse with the same rated currents and colors as shown in the table above.
