此步骤涉及以下诊断代码:

表 1
蓄电池故障诊断代码 
J1939 代码  CDL 代码  说明
(代码说明可能不同) 
备注 
168-31  E441(1)  蓄电池电势/功率输入 #1  发动机怠速已提高,以增加蓄电池电压。

此诊断代码并不表示故障。 该功能用于在发动机怠速时增加极低的蓄电池电压。 

可能原因

  • 充电电路

  • 蓄电池

  • 辅助装置

建议的措施

按所列步骤顺序完成以上步骤。

表 2
故障诊断与排除测试步骤  数值  结果 

1. 充电电路

A. 检查蓄电池充电电路的工作是否正常。 请参阅故障诊断与排除, "交流发电机故障"。
 

充电电路
 

结果:充电电路不正常。

修理:如有必要,修理充电电路。

结果:充电电路正常。

转至测试步骤 2。
 

2. 蓄电池

A. 确认蓄电池已无法再保持电量。 请参阅系统操作/测试和调整, "蓄电池 - 测试"。
 

蓄电池
 

结果:一个蓄电池不正常。

修理:更换故障的蓄电池。 请参考操作和保养手册。

结果:蓄电池正常。

转至测试步骤 3。
 

3. 辅助装置

A. 检查是否因为辅助装置一直处于接通位置而耗尽了蓄电池电量。
 

辅助装置
 

结果:由于辅助装置一直处于接通位置,蓄电池电量被耗尽。

修理:对蓄电池进行充电。 确认蓄电池能保持电量。 参考系统操作/测试和调整以了解正确步骤。

结果:辅助装置一直处于接通位置,但蓄电池电量未被耗尽。
