On-board computers today are one of the necessary and irreplaceable devices. The presence of such equipment, coupled with a regular trip computer, will make driving a 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" favorably differ from analogues by a large number of settings and functions that allow you to fulfill the requests of any users and configure the device to specific requirements. The car owner can independently group various parameters on the display, 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 responsible for the performance of these systems and other components. All vehicle systems are controlled by sensors and an ECU, which also stores fault codes for the entire system or individual sensors in its memory. Establishedthe on-board computers of the car do not display the codes of fixed errors, and if any occur, the driver may not notice the indicator lamp on the dashboard that has worked. In addition, when a signal is detected, it is difficult to determine whether it is possible to continue moving or it is better to stop.
Functionality
On-board computers "Multitronix" warn the driver in automatic mode and allow you 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 send the error log to your phone, mail address or any service station.
Some of the functions for diagnosing and managing the electronic systems of a car are performed not by the ECU, but by separate units, of which there can be more than 20 in one vehicle (for example, ABS, automatic transmission, EMUR, airbags, electrical 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.
On-board computers Multitronics fix and reset the errors of more than 60 such additional systems. Such a wide functionality makes working with such tools comfortable, guarantees the safety of travel, and saves time in the maintenance and operation of the vehicle.
If availablein an automatic transmission car, the on-board computer notifies the driver that the automatic transmission is overheating, and warns of the need for an emergency oil change.
On-board computers differ in feature set, display type, design and support for different vehicles.
The instruction manual describes 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 fall into two main categories:
- Universal. Synchronized with cars of any makes and models. In most cases, they are installed as an alternative to the interior mirror. Often these 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, Multitronics on-board computers are produced separately and are oriented to the VAZ-2109 and VAZ-2108 models according to the old dashboard. Such devices have greater efficiency and functionality and are installed in the dashboard of a car.
Separately, it is worth mentioning carburetor and injection models. The latter are more popular among motorists. As for the Multitronics on-board computers for the 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 vehicles is 1200-1300 rubles. More serious models with advanced functionality cost about 2,500 rubles and are equipped with a color display. New on-board electronics cost about 5-6 thousand rubles.
- For on-board computers of the brand "Gamma", for example, the minimum price is 3200 rubles, the maximum - 7 thousand rubles.
Installing the Multitronics on-board computer
The on-board computer can be installed by the car owner on their own without contacting service centers. The package includes not only instructions for the on-board computer "Multitronics", which describes in detail the installation process, but also a block of contacts. 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 trim.
The main problem that motorists face when installing a computer is the pinout of the connectors. The instructions provide a diagram that details which systems are accessed after connecting the on-board computer. For the correct functioning of the device, connect the K-line.
The K-line itself is the channel through which the most significant data is transmitted: information onerrors, engine temperature and others. Its connection is made to the main connector, which is located under the steering column on the left side. The kit for the on-board computer "Multitronics" comes with special wiring, with which the device is connected to the connectors.
No less important point in the installation is the connection of diagnostic connectors. Contact pads are of two types - Euro-2 and Euro-3. If the on-board computer "Multitronics" is incorrectly connected to the VAZ-2115, the diagnostics of the car and all systems will be carried out incorrectly.
Faults and device replacement
As motorists say, in the event of failure of the Multitronics on-board computer, the only way to troubleshoot is to replace it. Of course, the device can be repaired, but it is only repaired at service centers for large sums. It would be more expedient to purchase a new model and connect it yourself.
If the on-board computer gives out incorrect data, then it is likely that the contacts have come off as a result of shaking and vibration. The troubleshooting is very simple - just check the wiring and tighten the contacts in the right places.
Reviews indicate that the on-board computer starts to display incorrect information as a result of various failures. Car service is sent only in such cases. Specialists check the equipment and reflash it if necessary, updating the software.
Operation
Modern models of on-board computers have a wide range of functionality, covering more than 500 options. To master the device, you must read the instruction manual supplied with the kit. Reviews indicate that the main nuances that you should pay close attention to are the symbols and commands that report on the state of the systems and the car's engine.
Management
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 for changing lubricants or filters before the next maintenance are created using the keys of this category.
- System errors. System errors are displayed on the computer display. All error codes are listed in the instruction manual.
- Diagnosis. Information about the state of the car, its systems, nodes and main 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.
