MID 039 - CID 0247 - FMI 12
产生此代码的情况:
- 电子控制模块（ECM）检测到 J1939 数据链路上的连续 J1939 速度信号异常丢失。
- J1939 数据链路上从未接收到期望的连续转速信号。
故障诊断和排除:
检查 ECM 的配置。 如果发动机的 ECM 已错误配置成预期接收到一个连续的 "J1939" 速度信号，请在电子维修工具的主 J1939 屏幕上删除 J1939 速度信号的 "Continuous（连续）"设置。
测试步骤 1.
- 进行下述诊断步骤
- 使用 OEM 信息确定提供连续速度信号的机器 ECM。
- 请参阅 OEM 中的故障诊断和排除程序诊断有故障的速度信号
结果:
- 确定 - 停止
