The invention discloses a test method for diagnosing a fault code and a vehicle. The method comprises the steps that at least one diagnosis fault code test item is acquired based on a diagnosis fault code list of a target control unit, and the target control unit is a to-be-tested electronic control unit in a vehicle bus network; according to the at least one diagnosis fault code test item, performing diagnosis fault code test on the target control unit to obtain a test result; wherein the at least one diagnosis fault code test item is at least one of the following items: a recording function test item, a timeout test item, a bus closing test item and a message fault test item. According to the method and the device, the technical problems of relatively low systematicness and relatively low test efficiency of a diagnosis fault code test method provided by a related technology are solved.
本发明公开了一种诊断故障代码的测试方法及车辆。其中,该方法包括:基于目标控制单元的诊断故障代码列表,获取至少一个诊断故障代码测试项,其中,目标控制单元为车辆总线网络中的待测电子控制单元;根据至少一个诊断故障代码测试项,对目标控制单元进行诊断故障代码测试,得到测试结果;其中,至少一个诊断故障代码测试项为以下至少之一:记录功能测试项、超时时间测试项、总线关闭测试项和报文故障测试项。本发明解决了相关技术提供的诊断故障代码测试方法其系统性较低、测试效率较低的技术问题。
