并且UDS协议对Aging Counter这个参数用图详细说明: 如图中,每一个DTC Status bit如何触发以及怎么样转换。对于其中两点说明下: 1、标识2中,PendingDTC从1什么条件转0,协议中如下解释: pendingDTCis set to zero after an operation cycle in which the test completed and did notfail. 2、标识5中,ConfirmedDTC...
Driven and dependent on this pulse, each DTC has a dynamic status defined in ISO 14229-1:2013 (UDS standard). Bits 0 to 6 of the StatusOfDTC describe where the DTC is currently located in its life cycle. Figure 3:The dynamic behavior of DTC in the vehicle The figure above shows an ...
