OBD is an onboard automatic diagnostic system.
OBD is a system that monitors the operation status of vehicles and provides timely feedback on abnormalities, mainly monitoring the engine status and exhaust conditions of the vehicle. In the early days, OBD could only report the occurrence of faults in the form of indicator lights. Later, OBD could report various real-time data and standardized fault codes, making the diagnosis and repair methods of automotive faults undergo revolutionary changes.
The onboard automatic diagnosis system can also check the operation status of the car engine electronic control system and other basic functions of the vehicle during driving. When there is a problem with the system, the Fault Warning Light (MIL) or CheckEngine warning light will light up, and the OBD system will store the problem information in memory. The relevant information can be read in the form of fault codes through standard testing instruments and testing interfaces.
What is the system
The term “system” comes from the transliteration of the English word “system”, which refers to a whole with certain functions formed by the interconnection and interaction of several parts. Systems are generally divided into natural systems, artificial systems, composite systems, and physiological concepts. The methods used to describe systems include symbols, unit impulse response, differential equations, and graphs…
