E056 High Fuel Temperature Warning

Usage:

3054E 304
产生此代码的情况:

燃油温度超过触发点,延迟时间已经终止。 当燃油温度高于复位值时,电子控制模块 (ECM) 将复位警告。

ECM 检测到下述所有情况时:

  • 发动机至少已运转 3 分钟。 当发动机转速在低怠速设置的 50 rpm 以内时,此三分钟延迟开始。

  • 诊断代码0174-02 未激活.

系统响应:

ECM 将会记录该事件。 可以在电子维修工具的诊断屏幕上查看事件代码。

  • 燃油系统可能存在故障。

  • 燃油温度传感器可能存在故障。

测试步骤 1. 检查有无诊断代码

  1. 将电子维修工具连接到诊断接头上。

  1. 把钥匙开关转到接通位置。 不要起动发动机。

  1. 检查有无任何活动或记录诊断编码。

预期结果:

应没有任何诊断代码出现。

结果:

  • 确定 - 转至测试步骤 2。

  • 异常 -

    修复: 修理产生诊断代码的故障。 请参阅故障诊断与排除, "诊断代码的故障诊断与排除"中的相应主题。确认修理消除了故障。

    停止

测试步骤 2. 检查燃油系统

  1. 对燃油系统进行检查。 有关可能的原因,请参阅系统操作、测试和调整中的相应主题。

预期结果:

燃油系统中没有故障。

结果:

  • 确定 - 可能存在间歇性故障。

    修复: 监测发动机的运行。如果确定了间歇性故障,修理故障。确认修理消除了故障。

    停止

  • 异常 -

    修复: 对故障执行进一步调查。确认修理消除了任何故障。

    停止
