On-board computer OBD 2 and OBD 1
Content
First you need to decide which bookmaker you plan to purchase. Computers are divided into diagnostic, route, universal and control.
Modern technologies penetrate deeper into the spheres of society and industries. The automotive industry is also developing. To find faults and protect the environment, the OBD2 and OBD1 on-board computer was developed.
On-board computer via OBD
OBD is a vehicle diagnostic system that allows you to independently find errors and report on these problems.
A diagnostic connector is needed so that you can access the internal computing resources of the car. Having connected to it, specialists see information about malfunctions on the monitor.
OBD1
The first version of on-board diagnostics (OBD1) appeared in California in 1970. The system was developed in the air resources management office, where specialists were studying the waste that the car emitted into the environment.

After a long study of this direction, it turned out that only the OBD system can effectively control car emissions. So the first version of computer diagnostics of the car appeared.
OBD1 performed the following tasks:
- found problems in the computer memory;
- checked the nodes that were responsible for the production of exhaust gases;
- signaled to the owner or mechanic about a problem in a particular range.
By 1988 in the USA this program began to be used in many machines. OBD1 proved itself well, which prompted specialists to start developing a new, improved version.
OBD2
This on-board diagnostic has been developed from the previous version. Since 1996, it has become mandatory for gasoline-powered vehicles. A year later, without an OBD2 on-board computer, diesel-fueled vehicles were also banned from driving.

Most of the elements and functions of the new version were borrowed from the old model. But new solutions have been added:
- the MIL lamp began to warn of possible breakdowns of the catalyst;
- the system indicated not only damage in its radius of action, but also problems with the level of exhaust emissions;
- the new version of "OBD" began to save, in addition to error codes, information about the functioning of the motor;
- a diagnostic connector appeared, which made it possible to connect the tester and opened access to errors and functions of the car system.
How the device works
The connector is located no more than 16 inches from the steering wheel (on the dashboard). Most often they are hidden to keep out dust and dirt, but mechanics are aware of their standard locations.
Each important element of the machine has a sensor that allows you to find out about the state of this unit. They transmit information to the OBD connector in the form of electrical signals.
You can find out about the sensor readings using the adapter. This device works via a USB cable, Bluetooth or WI-FI and displays data on a smartphone or PC monitor. In order for information to be transmitted to an “android” or other gadget, you must first download a free application.
PC programs that work with OBD2 (on the ELM327 chip) usually come with the device on a disk and the drivers required for operation.
For Android tablets and phones, applications can be downloaded from the Play Market. One of the free ones is TORQUE.
If you select the Russian version in these applications, then the user will easily understand the functionality. A clear menu will appear on the monitor, where the parameters will be indicated, and it will become possible to access the auto components for diagnostics.
Advantage of OBD on-board computers
The modern OBD2 on-board computer has many advantages. Manufacturers note the following benefits:
- simplicity of installation;
- a large amount of memory for storing information;
- color display;
- powerful processors;
- high screen resolution;
- the ability to choose different software to make it more convenient to work;
- you can get data in real time;
- a large selection of bk;
- universality;
- wide functionality.
Tips for choosing
First you need to decide which bookmaker you plan to purchase. Computers are divided into diagnostic, route, universal and control.
With the first device, you can fully check the condition of the car. The diagnostic computer is usually used by specialists in services.
The second option appeared earlier than the others. Route is suitable for those who need to know the distance, fuel consumption, time and other parameters. Connected via GPS or internet.

The universal BC is connected to the car through the service connector. Controlled via touch screen or remote control. Such on-board computers are multifunctional. With their help, you can carry out diagnostics, find out the distance that has been overcome, turn on music, etc.
Control computers are the most sophisticated systems and are suitable for diesel or injection vehicles.
You need to choose, focusing on the budget, characteristics and the purpose for which the BC is purchased.
It is also important to pay attention to the models of well-known companies that are in demand among motorists. Do not forget to look at the warranty period of the product.
Price
The simplest models allow you to read error codes and monitor fuel consumption. Such on-board computers will cost the buyer in the range of 500-2500 rubles.
Prices for smart BC start from 3500 rubles. They read engine readings, find and correct system errors, show fuel consumption, display speed data on the screen, and much more.
Models that have all the control functions are in the price range of 3500-10000 rubles.
Reviews of car owners about on-board computers OBD
Daniel_1978
We spent a lot of time and money to find out the cost of Mark2. When I bought an OBD II ELM32 diagnostic adapter that works via Bluetooth, I coped with this task easily. The device cost 650 rubles. With the help of a free program from the Play Market I got access. I've been using it for a month. The good news is that for such a ridiculous amount I can find out about errors in the system, watch gasoline consumption, speed, travel time, etc.

I ordered an autoscanner for 1000 rubles via the Internet. The device helped to remove the Check Engine error, and to get rid of other problems, I downloaded the free TORQUE program. Connected to the BC through the "android".

I own a Hyundai Getz 2004 Dorestyle with an automatic transmission. There is no on-board computer, so I bought an OBD2 scanner (NEXPEAK A203). Works as it should, I managed to install it myself.

I bought ANCEL A202 for 2185 rubles. I have been using it for two weeks, I am satisfied with the device. I am glad that there are 8 colors of the main screen to choose from. I installed it according to the instructions in 20 minutes, no problems.
