Diagnostic Flash Code Retrieval
"诊断"灯
使用"诊断(DIAGNOSTIC)"灯或卡特彼勒电子维修工具来确定诊断闪烁代码。
如果发动机配备了"诊断(DIAGNOSTIC)"灯，请使用以下程序来检索诊断代码：
- 将点火钥匙转到 接通（ON）位置。 查看代码并不需要起动发动机。 点火开关处于接通(ON)位置时，发动机不需处于运转状态。
- 当点火钥匙在接通(ON)位置时，灯被检查是否工作正常。 任何活动代码都会在此时显示。
注: "诊断(DIAGNOSTIC)"灯将持续闪烁所有活动闪烁诊断代码。
- 当点火钥匙在接通(ON)位置时，灯被检查是否工作正常。 任何活动代码都会在此时显示。
- "诊断(DIAGNOSTIC)"灯将闪烁两位数字的代码。 闪烁顺序表示系统诊断信息。 两位数的每一位数是由点数闪烁次数来确定的。 灯以每秒两次的速率闪烁。 编码的两位数之间灯将熄停一秒钟。 代码之间灯将熄停两秒钟。
表1指示活动闪烁代码对发动机性能的可能的影响。 表1也同时列出电子诊断代码及其描述。
