History of creation

The OBD system was developed in the 1980s in the United States of America. Initially, it was conceived only to control exhaust emissions. The chairmen of the California Air Resources Board have begun to develop a new environmental standard for the country's cars. To control the safety of the vehicle, a special device was inserted into the control panel, onto which the necessary data was saved.

Then they could be counted and conclusions drawn about the safety of the car for the environment. Later, in 1988, development of a new system began. Vehicles that meet all OBD-2 requirements have been produced since 1994. The new system came into full force in 1996. It became mandatory for all passenger cars manufactured and sold in the United States.

In Europe, the system was adopted as the basis for creating requirements for the environmental safety of machines. Some European car manufacturers began using a 16-pin connector for OBD-2 testers in 1995.

What does the system consist of?

Important! The concept of OBD2 includes several elements.

This abbreviation should be understood as:

Connectors for connecting special devices. Devices that monitor the condition of the vehicle are inserted into them and collect data.
Connections. This could include wires, speakers, or any other device connections. Modern testers connect to the phone via Bluetooth or WI-FI.
A command system for data exchange between the electronic control unit and diagnostic devices.
Device connector standards.
Testers. These are special devices that can be purchased in the store. They are necessary to activate the system and communicate with your phone or tablet.

All elements form a single diagnostic system. It is able to identify problems occurring in the car and notify the driver about it.

How to connect the system?

To activate the on-board diagnostic system, you need to buy a special tester. It can be ordered from many online stores. It is important that the device is original.

Important! Fake testers may not connect to your phone or other device.

The system can be controlled from a phone or any other device. To do this, you need to install a special application on your device. In it you can see all the indicators that are transmitted from the tester. If an emergency situation occurs (a breakdown in the car), the OBD-2 on-board diagnostic system will analyze what happened to the vehicle and issue an error code.

All necessary information regarding the malfunction will immediately be sent to the gadget. To view the message, you need to open the application and write down the code that the system will issue. You can decrypt it yourself, using the Internet. Then you need to take the car to a car service center and report the breakdown.

Diagnosis of car errors

You can diagnose a car yourself not only using a computer, but also using mobile applications on the Android or Apple platform. There are many different applications on the Internet for this procedure, some of them can read vehicle code errors, find the cause and eliminate them. For example, for the OBD-II scanner there are special programs for Android that will tell you about all the car error codes and methods for eliminating them. In order to download it, you need to enter the name of the application on the play market “Deciphering OBD-II error codes”. In these programs you will find a lot of useful things, but the main thing is that the database contains all the car error codes.

If you use an Apple phone, then there is simply an ideal application for you to know what error codes are in your car, the program itself eliminates or deletes them. The application is sold with a cable for connection to the car. GoPoint Techonogy – works with GL-1 and BT-1 scanners. The scanner data and applications are official Apple applications, where GL-1 is a cable for connecting the car to the phone, and BT is a Bluetooth transmitter. The program not only helps eliminate car code errors, but also checks the operation of the engine, all sensors and much more. These two scanner-transmitters not only work with the native GoPoint Techonogy program, but are also compatible with DashCommand.

There are many applications, programs, scanners with which you can identify car error codes and eliminate them yourself. These maintenance services will cost a lot of money, but why pay for something you can do yourself? To use these applications, it is not necessary to have a professional level of computers and gadgets; you just need to know how to install the application. And may your car last for many years!

How to find out about a malfunction?

If any breakdown occurs in the car, a special sign will light up on the dashboard. Its name is Check Engine. Literally translated, it means “check engine.” Almost every driver has encountered this signal on their dashboard.

Check engine

The sign notifies that a malfunction has been detected in the vehicle’s power unit. You can check what's wrong using the OBD-2 system. You can reset the error using the app. In this case, the sign on the panel will stop lighting.

Important! When the Check Engine light is on, you need to get an error code and fix the problem at a car service center.

OBD-2 capabilities

Detecting faults in a car is not all that the OBD-2 system is capable of. Using on-board diagnostics you can:

Monitor work through the electronic control unit and monitor indicators. The screen of the device on which a special application is installed will display data regarding the condition of the engine and the health of its operation.
Analyze the performance of the vehicle's power supply network. You can also monitor individual elements of this system, for example, fuel supply.
Control emissions of exhaust gases into the atmosphere. If the amount of toxic substances produced by a car exceeds the state limit by 1.5 times, the MIL gauge on the dashboard lights up. The indicator informs the driver that his vehicle poses a danger to the environment.

Manufacturing companies

Today, OBD-2 testers are produced by several companies.

Important! Devices from different manufacturers differ in functionality!

The software on original devices is regularly updated. If the tester is produced by a company that is not supported by the manufacturer, it does not have this feature. Most often, counterfeit devices are produced in China.

You can tell if a device is of high quality by looking at its price. Both testers are sold for several hundred rubles, and devices for several thousand. For greater functionality, it is worth buying more expensive models.

The application interface for wireless connection also depends on the company. For professional use it is worth buying expensive devices. These include, for example, products from Launch. In addition to testers with a wireless connection to a phone, there are also those devices that connect to the gadget via USB. Similar models are found among both cheap and expensive devices.

obd2 diagnostic cable

Tips for finding errors in cars

When diagnosing a car for errors, look at the length of the cable that goes from the scanner to the computer - it should not exceed 5 meters. If the cable is more than five meters, the diagnosis may be incorrect

After you have purchased a scanner, carefully read the operating instructions.

You should turn on the ignition in the car only after connecting the scanner to the computer and completing the settings. This is necessary in order to exclude the possibility of damage to the on-board computer.

How to use an OBD-2 tester

In order to activate the on-board diagnostic system, you must purchase a special tester. The device can be purchased from many online stores. After purchase you need:

Find a connector to connect the device to the car. It can be located next to the driver's seat, on the dashboard, and so on.
Insert the device into the connector.
Install a special application on your smartphone or tablet. It is through it that it will be possible to read errors and monitor vehicle readings. The Torque program is suitable for the Android operating system.

Special application for obd2 diagnostics

Important! Special registration is required for professional OBD devices!

What should Peugeot 308 owners do without an on-board computer?

The OBD connector in 308 cars is located under the ashtray. Or under a plug that needs to be removed (see photo).

Hurray, we found the connector!

Data transfer takes place according to the standard OBD-II protocol. So, we connect the adapter, turn on the ignition and read the message... But the error is displayed via OBD in the form of numbers.

Universal and special software

Universal software is capable of many things:

Read parameters with minimal lag;
Read error codes ;
Remove errors.

Special software, in addition to other things, can change some parameters, as well as disable and enable different options. Example:

Citroen Lexia, also Peugeot Planet 2000 – software for Windows and adapter;
PSA DiagBox – software only (requires Lexia/PP2000 adapter).

Advantages

The strengths of the device include:

Compatible with many car brands. The tester connects to both domestic cars and foreign cars.
Small size and weight, compactness, ease of transportation and use. The device takes up almost no space in the car and does not distract the driver from the trip.
Ease of use of the device. The device does not require special knowledge and skills to operate it. Even an unprofessional driver can figure it out.
Possibility of connection with various devices. You can connect the tester to a phone, tablet or laptop.
Possibility of software updates for original models supported by manufacturers. From time to time, the functionality of the device will be improved, and old errors and shortcomings will be eliminated.
Versatility. The device can perform several functions at once: monitoring the vehicle’s condition, emissions into the atmosphere, reading and resetting errors, and so on. This is convenient because one device can perform several useful functions at once.
Clear application interface for communicating with the device. Every driver who is dealing with the application for the first time will easily understand the functionality and find the necessary option in a couple of minutes.
Quality. A device purchased from a reliable manufacturer will last a long time and perform all its functions properly.

Why is counterfeit dangerous?

Many unscrupulous manufacturers create fake OBD-2 testers. They sell them at a reduced price and at the same time promise that the device will work efficiently. However, there are several problems that owners of counterfeit OBD devices may encounter.

Short service life. Often counterfeit devices break down within a few months of purchase. Usually there is no guarantee on them, so it is impossible to either repair the device or return the money.
Connection problems. Applications for connecting to a tablet or smartphone cannot establish a connection with fake devices. Often the user receives a notification that the gadget was made by unofficial manufacturers.
Not all functions available. Fake testers often do not perform important functions. For example, through them you cannot check the performance of car systems, read the error code, and so on.

DECODING CITROEN AND PEUGEOT ON-BOARD COMPUTER MESSAGES

I am posting the main messages and Russian translation that the owner of a Peugeot or Citroen can see on the display of his on-board computer. This text was prepared by C4-Club.ru forum members Katya and Buka in 2008, for which I still thank them very much!

Another piece of advice is that you don’t need to throw tantrums when you find any messages. There are excellent online translation services: both in Yandex (translate.yandex.ru) and in Google (translate.google.ru).

Enter English or French text in one window and after a couple of seconds in another window you will see what it means in Russian. The translation of such a plan is of course a little clumsy, but the meaning can be understood in any case.

Pros: 1) you won’t bother the service center or your friends and acquaintances from the club to decipher foreign speech for you 2) you will increase your self-esteem and you will feel confident
