What is an OBD device?
1 Answers
OBD refers to the On-Board Diagnostics system. OBD is the abbreviation of On-Board-Diagnostics, which is translated as "On-Board Diagnostics System" in Chinese. This system continuously monitors whether the vehicle's emissions exceed the standard based on the engine's operating conditions. Once the emissions exceed the standard, it will immediately issue a warning. Here is more information about the OBD system: 1. How the OBD system works: OBD connects various emission-related component information to the Electronic Control Unit (ECU), which has the function of detecting and analyzing emission-related faults. When an emission fault occurs, the ECU records the fault information and related codes, and issues a warning through the fault light to inform the driver. The ECU ensures access and processing of fault information through a standard data interface. 2. Advantages of the OBD system: The useful information obtained after system self-diagnosis can assist in vehicle maintenance and repair. Maintenance personnel can use the vehicle's original factory-specific instrument to read fault codes, thereby quickly locating faults to facilitate vehicle repair and reduce the time for manual diagnosis.
