Onboard computer ("Niva Chevrolet"): instruction and installation
The car plays an important role in the lives of many people, and I would like it to work without fail, when it really is needed. To diagnose possible problems, manufacturers introduce a wide variety of electronic sensors, allowing time to respond to various deviations in the normal operation of all automotive systems. In order for the driver to be able to get information on changes in time, a measurement visualization is required, in which several control color diodes on the dashboard or a more advanced version - the on-board computer - act. "Niva Chevrolet" is produced with warning lamps, but it is possible to replace them with a full-fledged device for monitoring and diagnosing vehicle systems.
Basic concepts
As usual computers differ in performance, and models of automotive electronics differ from each other in functionality. Let's start by understanding what the on-board computer for Chevrolet Niva is, what better choice to avoid overpaying for the "extra" options.
There are simplified models designed to control fuel consumption, calculate travel time, average speed and some other basic parameters. Such devices are called trip computers and are used mainly in cars for cargo transportation. The limited functionality does not allow to display a large amount of diagnostic information about the operation of various systems of the car. Another thing - a full - fledged computer on the Chevrolet Niva. The instruction for such an apparatus abounds with the description of all sorts of functions, up to forced interference in the operation of the engine and other systems.
Popular solution
On the basis of Togliatti State University in 2007, an enterprise was created to develop and produce electronic automobile systems. For each modern model of the VAZ, the on-board computer "Staff" was released, on the "Chevrolet Niva" as well. Since 2009, the device "Sheva State" has been officially approved for use in these models of cars. One of the most popular models is the "State of Matrix" of various modifications. This device is compatible with Bosch MP7.0 and M7.9.7 controllers and operates according to the standard LADA OEM protocol.
In addition to collecting and displaying diagnostic information on the screen, the device is able to control the electric fan on the engine and the headlights. In the settings, you can reduce the temperature of the carburettor's air cooling, and the automatic switching on of the headlamps while driving will save the driver from unnecessary worries; moreover, the smart device will warn about unplugged headlights when the engine is stopped. In addition to the standard route computer, the model has a wide range of other functions: diagnostics over more than a dozen parameters, decoding and accounting for system errors, multidisplays and dynamics, as well as a special custom function key and alarm clock traditional for digital devices. These characteristics are enough for most users who buy an on-board computer. "Niva Chevrolet" under the supervision of an electronic assistant will be able to undergo maintenance on time and be repaired much less often.
Alternative Models
In addition to the "Chevy Matrix", "Staff" produces universal models with fastening on the windshield, also available for sale are various options from other manufacturers. экземпляр , чем описанный выше бортовой компьютер. Especially for this brand of mobile car developed a more advanced instance than the above-described on-board computer. с Multitronics C-570 готова предоставить информацию, которая для большинства обычных автовладельцев будет избыточной. "Niva Chevrolet" with Multitronics C-570 is ready to provide information, which for most ordinary car owners will be redundant. In addition, the computer is compatible with a taximeter and parktronic, is able to monitor the quality of fuel and is equipped with a large color display, capable of displaying data even in the form of graphs. The model is relevant for taxi drivers and other professionals who need additional system setup and diagnostics.
Presetting
Manufacturers say that the self-assembly of the electronic device is not too complicated, but to connect the device to the car will require at least basic skills and extreme accuracy. It is necessary to act according to the instruction, in order to avoid possible problems, which can cause the incorrectly installed on-board computer. "Niva Chevrolet", like any other car, requires de-energizing at any actions with the electric system, for which it is necessary to remove and remove from the battery the "minus" terminal, which is called "mass" in the people. Also, you should make sure that you have an immobilizer, if you do not have one, you will need to emulate the jumper on the OBD, as shown in the figure. This is an external temporary jumper, it is better to use terminals for permanent connection.
The procedure for replacing the BCL
For models that are replaced by a "lamp unit" on the panel:
The instrument panel should be carefully removed, for this you need to release the screws, 2 of which are above the steering column, right above the speedometer and tachometer. The other 2 screws are located under the decorative inserts on the right.
After removing the panel, you can release the block of warning lights from the latches. It is necessary to remember the order of connecting the connectors before dismantling the BKL, you never know what.
Plug with six contacts to connect to the computer, it must have a suitable connector.
To connect the ignition will require a T-bend. 1 contact six-channel connector must be connected to the cigarette lighter wire or ignition.
The next item is the on-board diagnostics connection, the connector is to the right of the steering column.
The computer will need a power source, for which you need to use one of the 12-pin plugs inside the dashboard. In order not to get confused in the wires, manufacturers conduct a standardized color differentiation:
Red and red-black colors indicate the main power + 12V.
Orange insulation means the ignition wire.
White and red-white colors lead to the vehicle's overall lights.
The black marking of the wire is a minus or a mass.
Now you can install the computer in the panel and fix it in place.
The second generation of "Chevrolet Niva"
Installation of the on-board computer on the Chevrolet Niva of the last issues differs somewhat from the one described earlier. There are some subtleties of connecting the ignition instead of the connector that is connected to the lamp unit. More information about this can be found in the appropriate place in the manual. The latest generation model is equipped with a security system by default, this should be taken into account when connecting the diagnostic connector.
Universal models BC
These models are equipped with standardized cables and wires of sufficient length, which facilitate the installation of the device on the windshield. Carefully read the instructions for each model to understand all connectors and connections.
First start-up and operation
After the installation and start-up, the onboard computers "Staff" and some other models operate in a demonstration mode, until the "Niva Chevrolet" is started. Errors of the on-board computer at power-up can be associated with the wrong choice of the type of control unit. In this case, you have to manually configure this parameter through the computer menu. For details on the detailed setting, please refer to the instructions that came with the device.
