On-board computers today are one of the necessary and indispensable devices. The presence of such equipment, coupled with a regular trip computer, will make the trip by car more comfortable and safer, providing the driver with comprehensive information about the condition of the vehicle.
Features of Multitronics computers
On-board computers "Multitronics" compares favorably with their analogues in a large number of settings and functions that allow you to implement the requests of any users and configure the device to specific requirements. The car owner can independently group on the display various parameters, adjust the notification system - both sound and visual, and connect parking sensors of the same brand.
Modern car models are equipped with electronic systems and various sensors that are responsible for the operability of the mentioned systems and other nodes. All vehicle systems are controlled by sensors and an ECU, which also stores fault codes of the entire system or individual sensors in its memory. Established on-board computers of the car do not display the codes of the fixed errors, and when they appear, the driver may not notice the lamp indicator on the dashboard. In addition, when a signal is detected, it is difficult to determine whether it is possible to continue moving or to stop better.
Functionality
On-board computers "Multitronics" warn the driver in automatic mode and allow you to decrypt 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 send the error log to your phone, mail address, or to any service station.
Some of the functions for the diagnosis and control of the vehicle’s electronic systems are performed not by the ECU, but by individual units, which in one vehicle can have more than 20 (for example, ABS, automatic transmission, EMUR, airbags, power accessories and many others). Diagnostic lamps on the dashboard, as a rule, do not display malfunctions of the systems mentioned above, respectively, the driver cannot be aware of their malfunctions.
Multitronics on-board computers record and clear errors from more than 60 such additional systems. Such wide functionality makes working with such tools comfortable, guarantees travel safety, and saves time on servicing and operating the vehicle.
If there is an automatic transmission in the car, the on-board computer notifies the driver of automatic transmission overheating, warns of the need for an emergency oil change.
On-board computers are distinguished by a set of functions, type of display, design and support for different cars.
The operating instructions describe how to connect the Multitronics on-board computer 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:
- Universal. Synchronized with cars of all makes and models. In most cases, installed as an alternative to the interior mirror. Often such computers are attached to the windshield.
- Customized. Such devices are designed either for a specific car model, or for cars of the same series. For example, for the VAZ-2110, the Multitronics on-board computers are manufactured separately and are oriented to the VAZ-2109 and VAZ-2108 models using the old dashboard. Such devices have greater efficiency and functionality and are installed in the dashboard of a car.
We should also mention the carburetor and injection models. The latter are more popular among motorists. As for the on-board computers "Multitronics" for the VAZ-2114, they are developed separately, taking into account the peculiarities of the torpedo.
Cost
Multitronics on-board computers 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 advanced functionality cost about 2500 rubles and are equipped with a color display. New on-board electronics cost about 5-6 thousand rubles.
- For on-board computers of the Gamma brand, for example, the minimum price is 3200 rubles, the maximum - 7 thousand rubles.
Installation of the on-board computer "Multitronics"
Installation of the on-board computer can be done by the car owner independently without contacting service centers. The package includes not only the instructions for the on-board computer "Multitronics", which describes the installation process in detail, but also the contact block. 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 pad.
The main problem that motorists encounter when installing a computer is the pinout of the connectors. The manual contains a diagram that details which systems can be accessed after connecting the on-board computer. For the correct functioning of the device, a K-line is connected.
The K-line itself is a channel through which the most significant data are transmitted: information on errors, engine temperature, and others. Her connection is made to the main connector, which is located under the steering column on the left side. A set of on-board computer "Multitronics" comes with special wiring, through which the device is connected to the connectors.
An equally important point in the installation is the connection of diagnostic connectors. There are two types of contact pads - Euro-2 and Euro-3. If the Multitronics on-board computer is incorrectly connected to the VAZ-2115, the diagnostics of the car and all systems will be carried out incorrectly.
Faults and device replacement
According to motorists, if the Multitronics trip computer fails, the only way to troubleshoot it is to replace it. Of course, the device can be repaired, but it can only be repaired at service centers for large amounts. It would be more advisable to purchase a new model and connect it with your own hands.
If the on-board computer produces incorrect data, then there is a high probability that the contacts have come off as a result of shaking and vibration. The fault is eliminated very simply - just check the wiring and tighten the contacts in the right places.
Reviews indicate that the on-board computer starts displaying incorrect information as a result of various malfunctions. They are sent to the car service only in such cases. Specialists check the equipment and reflash it if necessary, updating the software.
Exploitation
Modern models of on-board computers have wide functionality, covering more than 500 options. To master the device, you must familiarize yourself with the operating instructions that come with the kit. The reviews indicate that the main nuances that should be paid close attention are the symbols and commands that inform about the state of the systems and the car engine.
Control
Depending on the selected computer model, the number of functions and keys varies, but all of them can be divided into several categories:
- Maintenance. Commands to replace grease or filters before passing the next MOT are created using the keys in this category.
- System errors Computer errors display system errors. All error codes are given in the instruction manual.
- Diagnostics. Information about the condition of the car, its systems, components and basic details. Many models of on-board computers allow you to send commands to individual nodes of the car.
- Router There are many functions of this category of keys: fuel volume, black box, fuel consumption, average vehicle speed.
