In order to meet stringent emission regulation in US, it is mandatory to install the high efficiency NOx aftertreatment system in diesel application vehicle, SCR(Selective Catalytic Reduction), which is the latest technology on passenger car. Due to the application of new after-treatment system, the development of OBD(On Board Diagnostics) is necessary. In this paper, new OBD logic, control parameter and method of monitoring the malfunction of SCR system are shown for NOx efficiency monitoring, Front NOx sensor monitoring, Rear NOx sensor monitoring, Fault urea detection.
