Diagnostic trouble code(DTC):车辆或设备自诊断系统在检测到故障时生成的故障代码,用于指示异常类型与可能的故障位置;常见于汽车 OBD-II 系统中。(也常译作“诊断故障码/故障诊断码”)
/ˌdaɪəɡˈnɑːstɪk ˈtrʌbəl koʊd/
My car’s check engine light came on, and the scanner showed a diagnostic trouble code.
我的车发动机故障灯亮了,读取仪显示了一个诊断故障码。
After the repair, the technician cleared the diagnostic trouble codes and performed a drive cycle to confirm the problem was resolved.
维修后,技师清除了诊断故障码,并进行了行驶循环测试以确认问题已解决。
该短语由三部分构成:diagnostic(诊断的)源自希腊语 diagnōstikos,意为“能够辨别/识别”;trouble 表“故障/问题”;code 表“编码/代码”。合在一起即“用于诊断故障的代码”,在汽车电子与排放法规体系中逐渐固定为术语 DTC。
