How to fix "Check Hybrid System" warning on TOYOTA PRIUS - repair method

Here is English repair instruction to correct "Check Hybrid System" error happened on Toyota PRIUS.
In many case, this warning can be solved by filling Engine Oil, or exchanging 12V Lead battery, but in the worst case you may need to exchange HV battery or Inverter Unit.

There's many possibility to be recovered if you clean air cooling channel and blower fan blade cause stacking of the cooling air flow also generates check hybrid system warning and it often happens after 10 years of driving.

In my case, I did it in my Prius NHW20 (built year 2007) , and could eliminate this error after I cleaned up cooling duct and also ventilator blade as like this video instruction.
Trouble mechanism and repair theory can be same also for other Toyota’s pure hybrid cars such as Aqua(Prius C) and Lexus HS.

2:41 to watch how Cooling Fan is contaminated.
