What does it mean when the OBD light is on?
1 Answers
When the OBD light in a car is illuminated, it indicates that the vehicle's exhaust emissions are significantly exceeding the standard limits. This light serves as the engine exhaust system malfunction indicator. The primary cause of the OBD light turning on is an emission-related fault in the vehicle. Generally, the illumination of the OBD light rarely prevents the car from starting, meaning the vehicle can still be driven. However, it is recommended to seek repairs as soon as possible. Below is some relevant information about OBD: OBD stands for On-Board Diagnostics in Chinese. This system continuously monitors the working conditions of the engine's electronic control system and other functional modules of the vehicle while it is in operation. If any abnormal conditions are detected, the system identifies the specific fault based on predefined algorithms and stores the diagnostic trouble codes in the system's memory.
