开发的主要内容简单概括就是:应用报文开发、网管报文开发、休眠唤醒开发,及CAN网络相关故障开发,并没有涉及UDS开发,但虽然没有涉及开发,但多多少少都听过一点(特别是后来跑路的时候,恶补了学习了一手,嘿嘿)。 我刚开始接触诊断相关内容的时候,对诊断没有任何概念。所以听到同事们讨论什么SID啦、DID啦,DTC啦,什么27啦
统一诊断服务 (Unified diagnostic services , UDS) (六) 这篇文章将介绍InputOutputControlByIdentifier (0x2F) 和RoutineControl (0x31) 这两个诊断服务的用途和用法。它俩的作用有点类似,都是调用ECU内部一些预定义的操作序列,相当于是我们从外部利用诊断手段控制ECU的接口。 InputOutputControlByIdentifier (0x2F)...
