The invention relates to a fault diagnosis and processing method for a high-pressure water heating heater for a vehicle. The method aims at correctly and effectively recognizing faults of the high-pressure water heating heater in the vehicle driving process, the influence of the faults on vehicle driving is reduced through an effective processing method, and it is guaranteed that a driver drives the vehicle to a maintenance station for maintenance. The faults of the high-pressure water heating heater are divided into the class levels of LEVEL1, LEVEL2 and LEVEL3; the vehicle control unit diagnoses the three grades of faults and takes corresponding processing measures; the LEVEL1 fault is divided into a voltage type fault and an over-temperature fault; for voltage type faults, after it is determined that the PTC cannot conduct heating, the vehicle control unit actively closes an electric water pump in a warm air system; and for the over-temperature fault, after the fault of the water temperature sensor is confirmed, the vehicle control unit actively closes an electric water pump in the warm air system.

    本发明涉及一种车用高压水暖加热器的故障诊断及处理方法。旨在车辆行驶过程中正确有效的识别高压水暖加热器存在的故障,并通过有效的处理方法降低故障对整车行驶的影响,保证驾驶员驾驶车辆到维修站点进行维修。将高压水暖加热器的故障分为LEVEL1、LEVEL2、LEVEL3类等级;整车控制器针对三类等级故障进行诊断并作出对应处理措施;所述LEVEL1故障分为电压类故障和过温故障;对于电压类故障,在确定PTC无法加热后,整车控制器主动关闭暖风系统中的电动水泵;对于过温故障,在确认为水温传感器故障后,整车控制器主动关闭暖风系统中的电动水泵。
