Description

Technical Field

[0001] The invention relates to the technical field of automobile diagnosis, in particular to an automobile OBD bidirectional plug. Background Art

[0002] OBD is the abbreviation of On-Board Diagnostic, which is translated into Chinese as "on-board diagnostic system". This system monitors the operating status of the engine and the working status of the exhaust after-treatment system at any time. Once it finds a situation that may cause excessive emissions, it will immediately issue a warning. When a system fails, the malfunction light (MIL) or the check engine (CheckEngine) warning light will light up, and the OBD system will store the fault information in the memory. The relevant information can be read in the form of fault codes through standard diagnostic instruments and diagnostic interfaces. According to the prompts of the fault code, maintenance personnel can quickly and accurately determine the nature and location of the fault.
