Volkswagen Lavida can continue to drive when the OBD light is on. Definition of OBD: OBD is the On-Board Diagnostics system. This system continuously monitors the operating condition of the engine and the working status of the exhaust after-treatment system. Once it detects a situation that may cause excessive emissions, it will immediately issue a warning. When a fault occurs in the system, the malfunction indicator lamp or check engine warning light will illuminate, and the OBD system will store the fault information in the memory. Relevant information can be read in the form of fault codes through standard diagnostic tools and diagnostic interfaces. Based on the prompts of the fault codes, maintenance personnel can quickly and accurately determine the nature and location of the fault. Working principle of OBD: Through various emission-related component information, it connects 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 malfunction indicator lamp to inform the driver. The ECU ensures access to and processing of fault information through a standard data interface.
