|---|---|---|
| J1939 代码和说明 | 产生此代码的状况 | 系统响应 |
| 107-15 发动机空气滤清器 #1 压差：高 - 最低严重程度 (1) |
空气滤清器压差高于触发点压力已达到延迟时间。 | 记录该代码。 发动机功率可能会减额。 |
| 107-16 发动机空气滤清器 #1 压差：高 - 中等严重程度 (2) |

| 故障排除测试步骤 | 值 | 结果 |
|---|---|---|
1. 检查空气滤清器滤芯 A. 检查进气系统有无空气滤清器阻塞或损坏的情况。 |
空气滤清器滤芯 |
结果：空气滤清器滤芯堵塞或管路堵塞。 修理：清洁或更换空气滤清器滤芯。 并进行任何必要的修理。 确认修理后故障得到排除。 结果：空气滤清器滤芯和管路都没有堵塞。 转至测试步骤 2。 |
2. 护罩 A. 检查并确认发动机安装在通风良好的护罩中。 |
护罩 |
结果：发动机外壳通风不充分。 修理：修理外壳的通风装置。 确认修理后故障得到排除。 |
