On-board computer "Multiotronix": instructions and references

Onboard computers today are one of the necessary and indispensable devices. The availability of such equipment, coupled with a regular trip computer, will make the trip to the car more comfortable and safer, providing the driver with exhaustive information about the state of the vehicle.

Features of Multitronics

On-board computers "Multitronix" favorably differ from analogues with a large number of settings and functions that allow you to implement the requests of any users and configure the device for specific requirements. The car owner can independently group on the display various parameters, adjust the system of notifications - both sound and visual, and connect parktronics of the same brand.

Modern models of cars are equipped with electronic systems and various sensors responsible for the operation of these systems and other nodes. All systems of the car are controlled by sensors and the computer, which also stores fault codes of the entire system or of individual sensors in its memory. On-board car computers of the car do not display the codes of the fixed errors, and at occurrence of those the driver can not notice the working lamp-indicator on the instrument panel. In addition, when a signal is detected, it is difficult to determine whether it is possible to continue the movement or stop.

Functionality

Onboard computers "Multitronix" warn the driver in automatic mode and allow to decipher more than 10 thousand errors of the electronic engine control unit. The functionality includes storing all errors and entering information about them in the memory log with the registration of 40 parameters at the time of fixing the malfunction. Some computer models allow you to quickly forward the error log to the phone, mail address or to any service station.

Part of the diagnostics and management functions of the electronic systems of the car is performed not by the computer, but by separate units, which can be more than 20 in one vehicle (for example, ABS, automatic transmission, EMUR, airbag, power package and many others). Diagnostic lenses on the dashboard do not usually show a malfunction of the above systems, respectively, the driver can not be aware of their malfunctions.

Onboard computers Multitronics fix and reset errors more than 60 of these additional systems. Such wide functionality makes working with such tools comfortable, guarantees safety of trips, allows to save time of service and operation of a vehicle.

If there is an automatic transmission in the car, the on-board computer notifies the driver of the overheating of the automatic transmission, warns about the need for an abnormal oil change.

On-board computers are distinguished by a set of functions, the type of display, design and support of different cars.

In the operating instructions it is described how to connect the multitronic vehicle to the car - just insert the plug from the device into the OBD-2 diagnostic connector.

Types of on-board computers

All on-board computers are divided into two main categories:

1. Universal. Synchronized with cars of any make and model. In most cases, they are installed as an alternative to the interior mirror. Often such computers are attached to the windshield.
2. Individual. Such devices are designed either for a particular model of the car, or for cars of the same series. For example, for VAZ-2110, the onboard computers "Multitronics" are produced separately and are oriented to the VAZ-2109 and VAZ-2108 models on the old instrument panel. Such devices have more efficiency and functionality and are installed in the dashboard of the car.

Separately it is worth mentioning carburetor and injector models. The latter are more popular among motorists. As for the on-board computers "Multitronics" for VAZ-2114, they are developed separately taking into account the features of the torpedo.

Cost

On-board computers "Multitronics" are sold at the following prices:

• The minimum cost of an on-board computer for VAZ cars is 1200-1300 rubles. More serious models with extended functionality cost about 2500 rubles and are equipped with a color display. The novelties of on-board electronics cost about 5-6 thousand rubles.
• For the on-board computers of the Gamma brand, for example, the minimum price is 3200 rubles, the maximum price is 7 thousand rubles.

Installation of the on-board computer "Multitronix"

Installation of the on-board computer can be performed by the car owner independently without contacting the service centers. The complete set includes not only the instruction manual for the on-board computer "Multitronics", in which the installation process is detailed, but also the terminal board. With its help, the device is connected to the electronic connector. The connector itself is located at the bottom of the torpedo on the right side. To get to it, you need to remove the plastic cover.

The main problem that motorists encounter when installing a computer is the pinout of the connectors. The instruction shows a diagram, which details which systems are accessible after the on-board computer is connected. For proper functioning of the device, connect the K-line.

The K-line itself is the channel through which the most significant data is transmitted: error information, engine temperature and others. Its connection is to the main connector, which is located under the steering column on the left side. In the kit to the onboard computer "Multitronix" special wiring is delivered, by means of which the device is connected to the connectors.

Equally important in the installation is the connection of diagnostic connectors. Contact pads are of two types - Euro-2 and Euro-3. If you incorrectly connect the multitronic vehicle to the VAZ-2115, the car and all systems will be diagnosed incorrectly.

Malfunctions and replacement of the device

As the motorists say, in the case of the output of the on-board computer "Multitronics", the only way to solve the malfunctions is to replace it. Of course, the device can be repaired, however, it is only in the service centers for large amounts that it is repaired. It is more expedient to buy a new model and connect it yourself.

If the on-board computer produces incorrect data, then the probability is high that as a result of shaking and vibration contacts have disappeared. The fault is eliminated very simply - just check the wiring and pull the contacts in the right places.

The testimonies indicate that the on-board computer starts to display incorrect information as a result of various failures. The car service is sent only in such cases. Experts check the equipment and reflash it if necessary, updating the software.

Exploitation

Modern models of on-board computers have a wide functionality, covering more than 500 options. For the development of the device, it is necessary to familiarize yourself with the operating instructions supplied in the kit. The testimonials testify that the main nuances, which are worth paying close attention to, are symbols and commands that report on the condition of the systems and engine of the car.

Control

Depending on the chosen model of the computer, the number of functions and keys varies, but all of them can be divided into several categories:

• Maintenance. Commands for replacing grease or filters before passing the next maintenance are created using the keys of this category.
• System errors. Computer errors are displayed on the computer display. All error codes are listed in the operating instructions.
• Diagnostics. Information about the condition of the car, its systems, nodes and basic details. Many models of on-board computers allow you to send commands to individual parts of the car.
• Router. The functions of this category of keys are many: fuel volume, black box, fuel consumption, average speed of the car.
