Cause:
One or more additional fault codes that suppress urea metering are visible in the fault memory.
一个或更多抑制尿素计量的故障代码在故障记忆里显而易见。
Note:
The fault codes listed above are so-called system error codes/consequential faults, which are always displayed together with at least one other fault code in the engine/ SCR control unit of the instrument cluster (for example due to damage to lines, metering
valve, outside temperature indicator etc.).
以上罗列的故障代码就是所谓的系统故障代码/引发故障，这些故障总是和至少一个其他的在发动机/仪表SCR控制单元中出现的故障代码一起出现。（例如：由于线路损坏，计量阀，外部温度感受器等）
Remedy:
In order to erase the above faults, the fault code of the cause must be rectified first.
A test drive must then be performed.
为了取消以上错误，可能原因的故障代码要首先整改，试车再进行。
Note:
If possible, the test drive should be performed according to the following criteria so that the vehicle self-diagnosis function
is completed:
如可能，试车要遵循以下的标准，这样车辆自我诊断才能完成：
- Coolant temperature at least 80°C
- Catalytic converter temperature at least 250°C
- Drive for 5 min at a constant speed (no throttle blips, no acceleration) between 80 km/h and 90 km/h.
- After 5 min gradually increase speed to 100 - 110 km/h and then coast for approx. 15s - 25s. After the deceleration
phase gradually accelerate again to 100 - 110 km/h and repeat the procedure another 5 times.
冷却液至少80摄氏度
催化排气系统温度至少250摄氏度。
试车在80-90KM/H间恒速行驶5分钟，无油门信号和加速。
在5分钟后逐步增速到100-110，然后滑行15-25秒。在减速后，逐步加速到100-110并重复过程5次。
If the message in the instrument cluster continues to appear, stop the vehicle and switch off the ignition for 5 minutes
(ignition key removed, no diagnostic equipment connected).
如果仪表信息继续出现，停车并关掉点火5分钟。（点火钥匙要去除，没有诊断仪器连接。）
Afterwards the system error is merely logged as \"stored\" in the engine control unit and has no effect whatsoever on
the display or on the system function. The fault code can then be erased.
然后这个系统故障仅仅会储存在发动机控制单元中并不再影响运行和系统功能，故障代码可消除。
