Methods to resolve OBD faults: Quickly and accurately determine the nature and location of the fault by reading the fault codes, identify the problem, and then have it repaired at a 4S shop to eliminate the issue. Below is an introduction to OBD: 1. Introduction: OBD refers to a detection system extended for automotive fault diagnosis. 2. Principle: OBD continuously monitors systems and components such as the engine, catalytic converter, particulate filter, oxygen sensor, etc. It then connects to the ECU through various emission-related component information. When an emission fault occurs, the ECU records the fault information and related codes, and issues a warning through the fault light to notify the driver. The ECU ensures access to and processing of fault information through a standard data interface.
