1. Definition
OBD is the abbreviation of On-Board Diagnostics, which means on-board automatic diagnosis system. The OBD system monitors whether the car's exhaust gas exceeds the limit at any time from the operating condition of the engine. Once it exceeds the limit, it will immediately issue a warning. When the system fails, the fault (MIL) light or check engine (Check Engine) warning light is on, and the powertrain control module (PCM) stores the fault information in the memory, and the fault code can be read from the PCM through a certain program . According to the prompt of the fault code, the maintenance personnel can quickly and accurately determine the nature and location of the fault.
Simply put, the OBD system is based on a computer system to detect the performance of the main engine components and reduce emissions.
2. Composition
The basic OBD system is mainly composed of an ECU (Electronic Control Unit), which receives input from various sensors (such as oxygen sensors) to control the Actuator (such as fuel injectors) to obtain the required performance; check the engine indicator, Also known as MIL (fault indicator light), it provides fault warning to car owners, and can be accessed through DLC (diagnostic link connector). This DLC is also the OBD interface.Vehicle Tracking Device For OBD II is your good choice.
