5 伏传感器电源的连接 |
5 伏电源向变速箱油位传感器供电。 当 ECU 读取到信号线的电压低于正常值和/或对接地短路时,记录 FMI 04。
以下所列为导致此故障诊断代码的可能原因:
- 传感器电源电路对接地短路。
- 传感器出故障。
- ECU 有故障。 这不太可能。
注: 以下测试步骤可能会生成其他诊断代码。 忽略生成的这些诊断代码,并在修复原有诊断代码后清除这些忽略的诊断代码。 执行本步骤之前,请确保诊断代码 CID 0262 FMI 04 处于激活状态。
注: 使用数字万用表执行此步骤中的测量。
测试步骤 1. 检查传感器
- 将钥匙起动开关和断路开关转到接通位置。
- 从传感器上断开机器线束。 然后,观察诊断代码的状态。
预期结果:
诊断编码不是激活状态。
结果:
- 正常 - 诊断编码不是激活状态。 线束电路正常。 刚刚断开的传感器出故障。
修复: 更换传感器。
停止
- 异常 - 诊断代码仍为激活状态。 机器线束可能与接地间短路。 转至测试步骤 2。
测试步骤 2. 检查是否对接地短路
- 将钥匙起动开关和断路开关转到断开位置。
- 从 ECU 上断开机器线束。
- 在 ECU 的线束接头上,测量机架接地与传感器电源电路触点 J1-44(导线 709-OR(橙))之间的电阻。
预期结果:
电阻大于 5000 欧姆。
结果:
- 正常 - 电阻大于 5000 欧姆。 线束电路的电阻正确。 ECU 可能出现故障。
修复: ECU 不太可能会出现故障。 先退出此步骤,然后重新执行此步骤。 如果没有找到该诊断代码的原因,则应更换 ECU。 更换 ECU 之前,务必先咨询当地代理商的技术通信员征求 Caterpillar 可能的意见。 此咨询可以大大降低维修时间。 请参阅测试和调整, KENR8291, "电子控制单元 - 更换"。
停止
- 异常 - 电阻小于 5000 欧姆。 机器线束出现故障。
修复: 机器线束中的 709-OR(橙) 导线对接地短路。 有关更多电路信息,请参阅电气示意图, KENR8297。 检查电源电路中的所有线束接头。 确保接头清洁牢固。 修理或更换机器线束。
停止
