1 CDD中Fault Memory里DTC Column

当你打开一个CDD诊断描述文件时，在“Available DTCs Fault Memory”项中，你会看到这个CDD文件所有的UDS DTC List描述。在DTC List的每一Columu都有专用的术语描述，是不是经常被这些术语困扰！

各个术语描述见下表：

2 ODX/PDX中描述一个DTC用到的标签和关键字

CDD文件中，UDS DTC Columu使用的是In import target(name)列;

ODX/PDX文件中，描述一个UDS DTC，“”标签使用的是In import target(qualifier)列；“” 标签使用的是In import target(name)列。

详见该篇附录内容。

4 附录:ODX/PDX中描述一个UDS DTC举例

当你读懂该结构时，你可以尝试手动修改（或制作脚本）一个ODX/PDX里的若干个DTC描述。该示例以ODX V2.0.1标准协议为基础。

  B16555F
  DTC_96555F_XXX_Name
  
	
	  
		DTC_SHORTNAME

	  DTC_96555F_XXX_Name
	
	
	  
		SetCondition
		Set Condition
	  
	  Voltage > 14V,t > 2s
	
	
	  
		ResetCondition
		Reset condition & self healing
	  
	  Voltage < 10V,t > 5s
	
	
	  
		CorrectiveAction
		Corrective action
	  
	  No known corrective action
	
	
	  
		SpecialInstruction

	  tbd
	
	
	  
		DTC_OPERATION_CYCLE
		Operation Cycle
		
		  

			Kind of operation cycle for the event storage(e.g. power cycle, driving cycle, ...)
			

		  
		
	  
	  DEM_POWER
	
	
	  
		NUMBER_OF_TRIPS_ACTIVE
		Number of Trips - Active
		
		  

			Number of operation cycles needed to confirm the event

The value 0 is the standard UDS behavior of confirming the event (ConfirmedDTC status bit becomes set) with the first qualified FAILED result. A value of 1 means the event becomes confirmed if it fails again in the next operation cycle.
Larger values represent confirmation in the n-th cycle e.g. 2 is confirmation in cycle after the next cycle, etc.
			

		  
		
	  
	  0
	
	
	  
		Enable_Conditions
		Enable Conditions
		
		  

			An event status report ((Pre)Failed or (Pre)Passed) will only have an effect if all EnableConditions belonging to the DTC are met at the time of report. Otherwise the result will be discarded.
Multiple C-Qualifier separated by a comma can be added here

	  Yes
	
	
	  
		DTC_JUMP_DOWN_PREPASSED
		Use Jump-Down (Prepassed)
		
		  

			Switch for the activation of Jump-Down – only in combination with Jump-UP activation:

	  Yes
	
	
	  
		DTC_WARNING_INDICATOR_FLAG
		Set WarningIndicatorBit at fault
		
		  

			Yes -  the warningIndicatorRequested bit (bit 7) will be set at the same time as the confirmedDTC bit (bit 3) is set.
No - the warningIndicatorRequested bit (bit 7) is 0 at all times. 
			

		  
		
	  
	  supported
