Symptom Troubleshooting
采用以下故障排除指导:
了解机器操作。 了解症状是否具有正常工作或故障特征。
利用全部现有维修资料了解机器系统和执行故障排除。 阅读系统操作手册,以了解机器系统。 了解机器系统的相互作用。
向操作员了解症状情况,并获得以下信息:
- 故障前的机器性能
- 症状首次出现的时间
- 发生故障时的工况
- 故障前的事件顺序
- 所采用的故障排除步骤
- 机器修理记录
- 机器预防性保养
- 相关特定序列号维修信息
- 检查机器有无故障以及异常气味或噪音
尽可能复制症状。 运转机器并再现引起故障的工况。 检查仪表,查看有无异常指示。
确定电子控制模块(ECM)是否检测到故障。 诊断代码指明各个检测到的故障。
利用从操作员和您检查时获得的信息。 如果存在多种症状,则找到共同原因。
使用本手册中的测试和步骤来确定症状的原因。 一旦确定症状原因,修理故障。 然后,重新测试系统,以确认故障已排除。
共享故障排除信息。 执行正确的修理后,为 Caterpillar® 提供反馈意见。 利用维修信息系统(SIS)网站或基于部件的故障排除(CBT)中的反馈表单与 Caterpillar 进行沟通。 提供症状、测试和修理方面的简要说明。 请附上您的电话号码或电子邮件地址,以便与您联系。 这种反馈有助于 Caterpillar 改善服务信息。
