The coordination unit is an electronic device with "intelligent" connection coupling device To the car. It is necessary to protect the on-board network. vehicle from the superload, since even a minor effect from the outside can cause a failure in the operation of the electrocups.

It is optimally suitable for cars with a complex on-board computer, as well as equipped with multiplex wiring, CAN Bus Data, CHECK Control systems, alternating voltage electronic control, low voltage lighting.

Smart Connect is connected directly to the battery, so stable short circuit and voltage jumps on the network. The coordination unit for the universal electrician of the Farkop provides a number of important advantages:

    protection of electrical equipment TC in case of short circuit or other trailer malfunction;

    can be mounted on cars with lED lamps;

    notification of blinking lamps.

Principle of operation of the coordination block

It assumes the control signal of the electronic trailer equipment that is responsible for the function of one or another lighting. Thus, the electrical system of a car equipped with an on-board computer, multiplex wiring, etc., will not produce errors after installation to the trailer's vehicle.

What is the coordination block?

Recently, car owners, referring to the installation of a pardon in the service centers, increasingly hear offers to connect the electrician electricians and, accordingly, the trailer through the SMART Connect matching unit. But, as a rule, most people do not represent that it is and to such offers relate, as an attempt to earn more money on them. So let's figure it out what is the SMART Connect block and why it is needed when connecting the headcom.

If you know English a little, it becomes clear that Smart Connect is a "smart connection". And indeed, in the services, the installation of the coordination unit is offered only on modern cars, which are equipped with onboard computers and multiple electronic systems (ABS, EBD, ESP, TSP, ACC, etc.). No one will offer the installation of the coordination unit to the owner of the Muscovite or "Zhiguli", as it is simply not needed there and everything connects directly.

To connect and coordinate the work of all electronic systems of the modern car, a CAN-Bus tire is commonly used, which manages on-board computer. The more electronic systems have a car, the more wires should be. But due to the presence of a computer and CAN-Bus tires, all signals go along two wires, and the decryption blocks are installed in the right places, which already produce decoding and signal transmission to a specific sensor or mechanism.

How it all applies to the installation of a pardon and connecting light instruments passenger trailer? The fact is that to the block back The car also comes two wires, the signal is fed to the decoder, and 8-10 wires extends from it, along which the decrypted signal is already directly to the final device (dimensions, turn signals, stop signals, etc.).

It would be logical to assume that it is easy to connect a hitch without a Smart Connect block after a decoder, but everything is not so simple. With such a connection, the on-board computer is likely to give the Check Control error. The reason for this will be an increase in the load and resistance in the electrical network due to the trailer lighting, about which the car's on-board computer does not know and break it as a malfunction.

As a result, the computer's reaction can be the most different, ranging from attempting to disconnect the chain to incorrect work or failure of individual electrical components of the vehicle. It is from these troubles and saves the SMART Connect coordination unit for a land stick.

How is the connection through SMART CONNECT?

In the case of using the SMART Connect unit for, the connection to the electric car takes place as usual, by parallel connection using crimp clip. However, the wiring is connected not to the rosette of the headquart, but directly to the coordination unit, the block itself is connected directly from the car battery.

As a result, using such a connection scheme during the operation of a car with a connected auto receipt, we remove only the control signal on the inclusion of this or that light device, and the feed on the rosette of the headquart is already served from the matching block, which is connected directly from the battery. As a result, we have no increase in load and loss in electrical system The car, and the on-board computer does not register any extraneous connections, failures and malfunctions.

Electrician kits S. smart Connect for the headquarts are universal and are suitable for connecting to most modern cars. However, it is worth noting that if your car has a trailer towing mode, you need to connect the pork using the original matching blocks suitable for your car brand. Otherwise, this mode and function of monitoring the state of electrical equipment of the trailer simply will not work.

To date, most automakers seek to equip their products with the maximum number of modern electronic systems. However, all additional devices can have a detrimental effect on the automotive wiring and lead to sad consequences. This often occurs in cases where the equipment is connected directly.


You can collect and install the matching module.

The coordination unit is a device that provides the coordination of the car and trailer control system. It switches the fog on the trailer, controls the turn signals, and also turns off the parking sensors when the trailer is connected to the car.

In which cases is necessary installation of smart connect

When connecting equipment (headcom) by the method of "coarse force", the main onboard module of the vehicle reveals the invasion of extraneous consumers. It will be regarded as a systematic failure and provokes the wrong and inaccurate work of the main computer of the car. As a rule, the module issues an error message in such situations:

  • the vehicle is equipped with a multiplex type wiring;
  • earlier in the car was installed by an electronic monitoring system with alternating voltage;
  • the car is equipped with a CAN BUS DATA device (mainly installed in the case of an on-board computer device in the machine);
  • the car is equipped with a special SLF system, which scans the entire car for the presence of failed electrical lamps;
  • the vehicle is illuminated by the LED devices.

If your machine corresponds to at least one of the above items, then this means that if the installation of the headquart electrical outlet will be carried out directly, then with a huge share of the probability it will provoke serious failures in the work of a large number of electronic car systems.


The board of the matching module after soldering do it yourself.

The system of coordination module The smart connection provides for the duplication of each power circuit of the trailer load circuit. The principle of this device is as follows. Upon admission from the central computer of a car notification that the activation of a particular light source is needed, the smart connection gives a control signal to turn on the specific voltage circuit. It also regulates the load so that it does not differ from the usual. The smart connector device provides for the preservatives required to protect the headquart from the unnecessary voltage on the network. Thanks to these fuses, the on-board computer of the vehicle does not notice any changes in the voltage of the automotive network and does not record the error. Accordingly, this ensures the normal operation of all systems.

It should also be remembered that even in many cars outdated models before installing a pardon, a coordination unit is required. This procedure is relevant in the following situations:

  • if there is a chance of fire. As a rule, if additional electrical appliances are installed in the car, it causes the need to increase;
  • nominal patent fuses. This is due to the increased load on everything. power chains vehicle. The same applies to rotary lighting devices, as well as dimensional lamps. Such jumps will lead to accelerated wear Details, as well as violation of its work. Because the majority of cars on which the mounting of the Farkopa was produced, most Time is still used without trailer, such exploitation can cause damage to the wiring and the fire of the fuse itself;
  • if at the time of connecting the pharg and the trailer to the car in its electrical circuits already have problems, it instantly provokes the fuse brave. Faulty fuse may entail brake, overall and emergency lights;
  • if you decide to take advantage of another trailer (for example, by taking it for rent or lent in a friend), it may turn out to be a completely different type. It will also instantly entail the brave of all automotive fuses and turn off the whole light.

Collect the mounting chassis with your own hands

If you have already installed a pardon, then the installation of a smart connection will be a panacea from all cases above. The apparent block device implies the built-in high-end protection. In the car's power grid, short circuit or overload will never happen.

Also, spare relays are built into the smart connected, which completely eliminate the chance of overvoltage of electrical networks in case of connection, for example, a trailer with a trailer. The coordination unit has high levels of resistance to network voltage jumps.

Smart Connect Connection Algorithm

The smart connector module must be connected directly to the battery. Also, the device is connected to the device, the oil sensor, fuel valve And, directly, on-board computer. The algorithm for connecting the smart Connect to the power grid is presented on this scheme:
