TID/ CID组合。测试结果是一个无符号的正数。每条测试结果只有一个限值,既可能是上限,也可能是下限。如果上下限值都要被输出的话,它们必须分作两条输出。这项服务也可以用于www.eboatcom输出模式5中氧传感器的测试结果。模式6中输出的信息也是某个部件或系统的监测结果。每条信息对应一个测试标示( Test id),信息中也包含测试值、最大值和最小值。模式6同模式5有以卜不同模式6中的TID由厂家定义,只需要遵循15031-5中定义的格式输出即可不同的厂家可能使用不同的TID定义,因此必须了解相应的定义才能解读模式6中一个TID可能有多个测试结果,每个测试结果对应不同的指标,通过CID来区分。模式6中的测试结果只能是正数,多是一个无单位的指标。模式6中每条结果( TIDICID)只能指明个边界值,比如如果想输山某个测试结果以及其正常值的最大和最小两个边界,那么必须通过两条信息分别输出首先要请求支持哪些 OBDMID。参数名Hex数值请求OBD监测服务的SID06OBD-MIDXⅩOBD-MIDXⅩOBD-MIDXⅩ、。也以上的MID为$00,$20等等参数名Hex数值请求OBD监测服务的正响应SID461支持的
