According to the requirements of the NOx control system, when detecting low reagent level, abnormal reagent quality, low reagent consumption, SCR system injection interruption, EGR valve sticking, or tampering faults related to sensors, the driving performance limitation system will be activated if not corrected in time. Before activating the driving limitation system, the driver warning system will notify the driver with a visual alarm. Below is more information about the driver warning system: 1. What is the driver warning system: The purpose of the driver warning system is to ensure the normal operation of the NOx emission control system, especially the urea system, to meet NOx emission requirements.
