Car diagnostics on a laptop: how to do it yourself?

Pros usually advise for newbies the standard scanner “Smart Scan Tool” , since with other options there can be all sorts of problems - from model incompatibility to the possibility of serious disorder of the electronic system of the machine.

Computer diagnostics of cars already has quite a solid history, exceeding the 35-year period: in 1980, General Motors introduced on a commercial basis the diagnostic interface ALDL to monitor the state of all vehicle systems, as well as the ECM protocol used for diagnostic tests of the control modules of the propulsion unit.

In the early 1990s, a universal diagnostic protocol for motor vehicles was created in the United States: best obd2 scanner (On Board Diagnostic), and since 1996 its upgraded version of OBD-2 has become technologically indispensable for US cars and Canada.

Since 2000, the European version of this protocol (EOBD), the EU Directive (98/69) has been introduced into the EU autos produced and sold on a mandatory basis for gasoline vehicles, and since 2004 for diesel ones.

Japan introduced its own version of the protocol (JOBD) in 2003 for all its machines.

That is, now, generally speaking, the vast majority of even very old cars (up to 20 years old) are adapted to the computer diagnostics system. And for these historical milestones, you can assume the presence or absence of this adaptation in a particular car.

Electronic control unit
Modern vehicles are equipped with an electronic brain that integrates diagnostic sensors and control modules of all systems and subsystems of a vehicle, through which you can monitor the current state, make performance predictions, adjust various technical parameters and fix some problems.

Such a center is called an ECU (electronic control unit) and, for technical monitoring or making any changes and corrections to the auto system, an external diagnostic interface is connected to it.

hat he really is?

Usually it is a bunch of special controller (OBD-2 protocol specifier), some kind of processor for data processing, special software and means of connecting all of this. Now I will explain to you in more Russian, what is the point, presenting a general concept:

The computer of the machine must have an external output-connector, to which a key element for such diagnostics is connected - an OBD-adapter (scanner), which converts and unifies the data flow from the computer controller so that they can be read by external plug-in devices.


The most complete practical BB GLOW Treatment course
and mezonidling (5 in 1)

Become the top masters of the city, get your hands on the 5 main procedures: BB + Glow Treatment Effect to kiss the lips + Meso of anti-age / lifting + + Meso Meso old body of CO2 at a rate of 100% result.

super efficient
meso procedures in one course , adapted
specifically for European leather
Without pain and swelling. No seasonal restrictions. Absolute security.
Visible result after the first procedure. Short rehabilitation period (up to 1 day). Super resistant effect: up to 1 year.

The most complete program.
100% top practice. Guaranteed
posing hands from A to Z
On the course we master 5 top procedures. We provide a complete starter kit for 20 procedures with everything necessary for carrying out the whole complex of meso procedures (from 6 types of original serums to derma-foam and cartridges).

We do not learn to "stick"

serum under the skin

We teach effective, and most importantly safe technology

#BB GLOW EUROPEAN SKIN fully adapted for

European skin type . With precisely matched sera, cartridges, needles and post- treatment procedures.

99% of the training procedure BB GLOW looks like this: “Girls, everything is simple. Here is the serum. Here is a Chinese derma-pen. Apply and "stick".

Without skin diagnostics. Without a combined approach. Cartridges for 36 needles according to the Korean protocols.

It is important to remember that the ancestor of the “BB GLOW treatment” procedure is South Korea and was originally created for Asian skin type . Their skin is dense, the fibroblasts are larger, the collagen in the dermis is larger and they age in muscular type.

Therefore, the existing Korean protocols of the procedure and a number of sera are not suitable or completely contraindicated for European skin. If the procedure is carried out according to the Korean protocol, then the European client at best will turn red for 4-5 days.

We teach from scratch ,
and 100% guarantee that immediately after the course you can safely begin to practice independently.

The most complete starter kit

with everything you need to hold the whole

complex of meso procedures

All serums: 100% original. 100% tested. 100% effective. We have tried dozens of serums and mez cocktails, and we know what really works.

The most efficient and reliable derma-pen.

Someone has a small number of revolutions, someone has an inconvenient gearshift, someone has a slippery holder, from which the arm quickly gets tired, someone has only 2 mm needle projection.
