UDS(Unified Diagnostic Services)统一诊断服务中的0x19服务是用于读取诊断故障代码(DTC,Diagnostic Trouble Code)信息的服务。DTC是车辆故障诊断系统中的重要部分,当车辆发生故障时,相应的DTC会被存储在ECU(电子控制单元)的故障代码存储器中。 0x19服务包含了多个子服务,每个子服务用于读取不同类型的DTC信息。以下是其中...
ODX/PDX文件中描述一个UDS DTC,“<SHORT-NAME>”标签使用的是In import target(qualifier)列;“<LONG-NAME>” 标签使用的是In import target(name)列。详见该篇附录内容。 3 CDD中Fault Memory里DTC Column与Autosar Dem参数对照表 DTC Column中标题 PDX中标签/短名 值 DEM中参数名 DTC TROUBLE-CODE DemUds...
在计算机内存中的信息称为“故障诊断代码”(diagnostictrouble code ,DTC)和”冻结帧数据” (freeze frame data) 。冻结帧数据是发动机和控制系统当前状态下所有可获得的信息。在连续三个无故障驾驶循环后,应该熄灭 MIL。 在40 个无故障驾驶循环后, OBD 系统可清除该故障代码和冻结帧数据。 6.3诊断 ...
Depending on the selected 0x19-ReadDTC subfunction, the FreezeFrame or the corresponding ExtendedData information must be decoded in the tester in addition to the DTC. Of course, the coding of the UDS data in the ECU, based on DEXT, must be identical to the decoding based on ODX. Figure...
技术标签:UDS 一、服务说明 DTC设置控制服务(ControlDTCSetting)简称CDTCS诊断服务,客户端通过该诊断服务停止或恢复诊断故障码的设置。 开启DTC:子服务代码是0x01,服务器应该继续更新诊断故障码状态位 关闭DTC:子服务代码是0x02,服务器应停止更新诊断故障码状态位 当启用了DTC关闭后,若会话跳转到不支持$85服务,ECU应...
