Hi all. I have 2013 CT200h (Prius g3 in disguise). As there is not so much Lexus hybrid issues related forums out there, I am turning here, hope you will forgive me. Today my wife drove home and check hybrid system with master warning, brakes,vsc and engine light came up. She drove up the last mile without problems. Now when at garage home when I start the car, it turns immediately the ICE on and the invertor start its high pitch whine (like when its charging). When i turn it only to ready state (without brake pedal depressed), it only starts the battery fan (at rear passenger side) and nothing else, no other sound, i cant see invertor coolant movement and hear no pump sound. And it of course beeps and show all the warnings with check hybrid system again. So - I know i should get to my dealer and get scanned for fault codes, but it is friday afternoon here and my technicican just got away for weekend. Do you have any ideas, what it can be? Is it “only” pump, or? Thanks!
And I have checked 12V battery, it has 12,4V and its charging now, but I am not assumimg that this is not the issue, right? When I turn on the car to ready when its on charger (via terminals under hood), there is no change, still faults and beeping and all . . .
welcome! how many km on her? it certainly seems you need an inverter pump. if the engine starts, the 12v is fine.
