dephi OBD II 技术路线,所谓OBD-II是一个系列的法规，目的是通过检测整个动力总成系统的故障或劣化来减少在用车的排放，排放控制系统是OBD-II的基础。OBD-II同时也提供诊断的标准化，修理及其他相关服务的标准化。当车辆的排放（HC,CO,NOx)由于被检测的零部件/系统的劣化而超出相关标准的1.5倍时，故障指示灯（MIL）必须被点亮以通知驾驶员，并同时记录故障码。-dephi OBD II technology roadmap, the so-called OBD-II is a series of regulations aimed at detecting the entire powertrain system to reduce the failure or deterioration in car emissions, emissions control system is based on the OBD-II. OBD-II also provides the standardization of diagnosis, repair and other related services for Standardization. When a vehicle emissions (HC, CO, NOx) were detected as a result of the components/systems and the deterioration in excess of 1.5 times the relevant standards, the malfunction indicator light (MIL) must be lit to inform the driver and at the same time recorded fault code .
