Hi y’all, Have a 2010 Toyota Prius, my Check Hybird System can one just about a day ago. (Happened back in October as well, but I just unplug the white cord from the fuse box and lasted me about 3 months - thinking everything was okay). (Additionally I got my water pump replaced back in October after the warning came on). A day ago it came back on (tried to do what I did back in August but didn’t work well this time) struggled because stability control lights came on and wasn’t able to drive the car at all, so had to get it towed back home. Now the check hybrid system lights are on, stability control, and now my check engine, brake, charging system, electric power steering, and ABS warning lights are all on as well. Can anyone give me an idea what’s wrong with the car? Thanks in Advance. (Can’t realer go to a dealer since it’s used and no warranty)
There's error codes stored to pinpoint the problem that needs fixing... You can get an auto parts store to read them for free, but they won't be able to read the sub-codes. For that you need to use Toyota Techstream software a Mini-VCI plug, or even easier, a the Dr. Prius app and an OBD2 Bluetooth device.

start with the 12v health and oil level, then code reading. in the meantime, inspect and clean the hybrid battery cooling dan, make sure the intake grille is clear, and check the inverter fluid reservoir for movement when the car is made 'ready'. does it have all its regular maintenance done?
