How to use an OBD reader
What does an OBD scanner have to be able to do?
OBD stands for On Board Diagnosis. The OBD was originally developed in the USA. Back then it was about ways to reduce air pollution in larger cities like Los Angeles and San Francisco. The second development stage, OBD 2, also written OBD II, is already in use today. In the USA, OBD 2 came into force in 1996. Europe adopted the standard a little later, slightly modified, in 2001 and consequently calls it EOBD.
Uniform diagnostic system
OBD diagnosis enables standardized diagnosis of almost all vehicles worldwide. Not only the exhaust gas diagnosis is carried out, but an analysis of the entire vehicle electronics. Today, it is hard to imagine maintenance and fault detection without OBD diagnostics. Modern vehicles can currently hardly be checked through their paces without a diagnostic scanner and corresponding software or scan tools.

Properties of OBD diagnostic devices
OBD systems are not only used to love the environment and to protect people and nature. It should include Engine damage can also be prevented through the consistent use of OBD. When connected to the engine's electronics, emergency programs are run via OBD, which pay particular attention to efficient engine protection. Loose spark plug cables or broken cables are detected early and appropriate measures can be initiated. An OBD system can switch off a cylinder completely and prevents unburned fuel from damaging the catalytic converter.
The simplification of maintenance and repair work on vehicles is also an important feature of OBD scanners. All of the information collected by the OBD system can be used to specifically advance troubleshooting based on the symptoms that have been discovered. It is important that the manufacturer of the respective OBD system provides sufficient documentation that describes each error message in detail.

The most important properties of OBD scanners also include these explicit functions:
Permanent monitoring of all components relevant to exhaust emissions
Constant recording and reporting of increases in emissions while the vehicle is in constant use
Ensuring low exhaust emissions
Protection of vehicle components such as catalytic converters
Saving all data from errors that have occurred
Availability of a suitable or standardized interface for reading out all stored data and current operating data
