如果系统工作中发生错误,故障消息将出现在显示器上。 通过显示器和 Caterpillar 电子技师(Cat ET)可获取错误和故障的更多信息。. 系统的故障诊断与排除可能需要"电气系统示意图、液压系统示意图和操作与保养手册"中的更多信息。

执行线束接头的连续性检查,确定线束故障位置。 务必检查部件接头上的接地电路。 在任何系统接地和机架接地之间,电阻必须小于五欧姆。 大于五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它部件出现故障。 同样,一个电气部件的故障可能是由其它部件的故障引起的。 在更换部件之前,务必先尝试排除电气系统故障的原因。
