    • Provided is an on-board machine capable of readily examining whether a self-diagnosing mechanism operates in a normal manner while satisfying statutory requirements. The on-board machine includes an EEPROM for storing a failure diagnosis executing frequency calculated on the basis of a failure diagnosis executed by an electronic control device under a predetermined travel condition set in advance, and a control portion for transmitting the failure diagnosis executing frequency stored in the EEPROM in response to a transmission demand for the executing frequency of the failure diagnosis from an external frequency collecting device 3 when the failure diagnosis executing frequency is within a predetermined frequency range.
    • 提供一种能够容易地检查自诊断机构是否以正常方式操作同时满足法定要求的机载机。 车载机包括EEPROM,用于存储在预先设定的预定行驶条件下基于由电子控制装置执行的故障诊断而计算出的故障诊断执行频率;以及控制部分,用于发送故障诊断执行频率 响应于当故障诊断执行频率在预定频率范围内时来自外部频率采集装置3的故障诊断的执行频率的传输需求的EEPROM中。
