This type of connection is called <strong>CANopen<\/strong>.<\/p><p>Unlike OBD1 protocols, which were designed to diagnose only certain problems on certain vehicles (for example, certain emissions-related problems on older cars), OBD2 can diagnose a wider range of problems that affect all cars, regardless of or their age.<\/p><h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Comment_utiliser_un_lecteur_OBD2\"><\/span>How to use an OBD2 reader?<span class=\"ez-toc-section-end\"><\/span><\/h3><h4 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Necessite_dun_Lecteur_OBD\"><\/span>Need for an OBD Reader<span class=\"ez-toc-section-end\"><\/span><\/h4><p>To understand why an OBD reader is essential, you must first understand what a vehicle&#039;s OBD is:<\/p><p>THE <strong>on-board diagnostics (OBD)<\/strong> is an electronic system that monitors your car and its components while you drive. It allows any problem detected to be diagnosed in real time, rather than after the fact, when the engine has already started! The first OBD systems were intended for American cars under the name <em>OBD-I<\/em>. These systems consisted of four terminals to read information such as speedometer, tachometer, temperature sensors, etc.<\/p><p>Nowadays, the second generation of this system, <em>OBD-II<\/em>, is very widespread. It consists of five terminals that monitor engine parameters such as speed, fuel consumption, emissions, oil pressure, coolant temperature, battery voltage, etc. These readings come from sensors installed in the engine, not an OBD reader.<\/p><h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"En_Conclusion\"><\/span>In conclusion<span class=\"ez-toc-section-end\"><\/span><\/h2><p>Most vehicle manufacturers include a diagnostic menu in their scanners. This menu, usually a single page, is user-friendly and allows you to perform factory checks, troubleshoot and identify potential problems, as well as adjust values for different systems. This menu is often displayed in a dedicated window on a computer screen, often in the form of an on-screen display (OSD) window. To use it effectively, consult your vehicle&#039;s owner&#039;s manual to familiarize yourself with the diagnostic system, its buttons, and available menu options.<\/p><p><em>Read our review<\/em> to find out which is the best OBD2 car diagnostic tool!
