Automobile dashboard indicator OBD stands for the engine exhaust system malfunction indicator light. Here is relevant information: 1. There are many reasons that may cause the OBD light to illuminate, mainly related to vehicle emission faults. Generally, the illumination of the OBD light rarely prevents the car from starting, meaning the vehicle can still be driven. 2. This highlights the importance of the OBD light. If ignored, it could lead to pollutant emissions hundreds of times higher than normal vehicles. Therefore, when a fault causing excessive exhaust emissions occurs, the OBD light will illuminate to promptly alert the owner to repair the fault as soon as possible.
