通过下述工具之一可以访问 ECM 诊断:操作员监视系统 和 Cat® 电子技师 (Cat ET) 维修工具。 为诊断和排除机器电子控制系统的故障,需要从机器的维修手册中获得更多信息。 下面列出了所需的一些支持资料:

  • 操作手册, KENR9509, "挖掘机 E-系列监视器"


  • 系统操作, UENR5674, "336D2 XE 挖掘机机器系统操作"

  • 测试和调整, UENR5675, "336D2 XE 挖掘机机器系统测试和调整"

  • 示意图, UENR5906, "336D2 XE 挖掘机液压示意图"

  • 示意图, UENR5907, "336D2 XE 挖掘机电气示意图"

  • 操作和保养, SEBU9254, "336D2 XE 挖掘机操作和保养手册"

  • 操作/测试和调整, UENR5676, "336D2 XE 机具控制系统操作/测试和调整"

本手册结尾含有一幅典型的系统示意图作为指南。 有关正在诊断的机器的准确示意图,请参阅维修手册中的 电气系统示意图。

当故障诊断和排除步骤指出需要"修理或更换线束"时,请使用正在维修的机器的电气系统示意图来追查电路。 执行线束接头的导通性检查,确定线束故障位置。 务必检查部件接头上的接地电路。 接头的接地触点与机架接地之间的电阻应小于 5 欧姆。 ECM 电源电路在接地接头触点与机架接地之间的电阻应小于 2 欧姆。 为确保正常工作,信号电路的电阻应小于 5 欧姆。 大于 5 欧姆的过大接地电阻会导致故障诊断发生错误。

故障诊断和排除过程中,在更换任何部件之前应先检查所有连接。 如果这些连接不清洁、不牢固,则可能会导致永久性电气故障或间歇性电气故障。 检查并确认已将导线完全推入接头中。 在进行其它测试之前,确保所有连接牢固。

一个电气部件的故障可能会导致其他部件出现故障。 同样,一个电气部件的故障可能是由其他部件的故障引起的。 在更换部件之前,务必先尝试排除电气系统故障的原因。
