Car turned off suddenly, won't restart or go into ready mode

My guess is the AM2 fuse blew (it a big metal fuse; doesn't look like a regular fuse). You're in luck, there's a great prius resource who serves the DFW metro-mess: Texas Prius Battery Replacement

GOOD LUCK!

 

Check the OBD2 codes, you most likely have a P0A93... aka a bad inverter pump.

Turn on the vehicle and look for turbulence in the inverter pump coolant reservoir, if you don't see such or are unsure, then take a stick or a finger and touch the pump and feel for a vibration.

Don't replace the AM2 fuse without replacing the inverter pump first, as it will blow again.

 

Yeah, the fuse is most likely blowing because the inverter pump has failed and is shorting (common). Matt can get u fixed up in your driveway if this is something you don't want to handle.

 

Just unplug the pump motor connector and replace the fuse. If you're looking at the engine compartment fuse box, the plug connector is about 2 inches away from the upper left corner of the fuse box. It's the only plug connector in that area. Unplugging that should at least keep the fuse from blowing and allow you to operate the car at low speed until you can replace the pump.

The AM2 fuse kills the entire dashboard and MFD. No AM2=not going anywhere

 

for a car thats meant to be rock solid and reliable its very disturbing that an issue an occur where you cant turn the car on and put it into neutral to move it around and get it towed.

i think thats a serious flaw with the prius. There really should be a way to put it into neutral when its completely dead.

 

You've being told to unplugged the inverter pump connector, and drove the car only short distances until you get the pump replaced.
Y are you still in doubt about what the issues could be, or something?

 

It's not always easy to tell if a given poster is trying to fix something properly or if they're just desperate to move the car another mile to get it into a garage or something.

Replacing the inverter coolant pump would be the right permanent fix.

A bag of ice would keep the inverter cool enough to move the car. Maybe far enough to get to a parts counter or an auto recycler.

 

That's too far for an inoperative inverter cooling system.

 

I've given all the suggestions I feel comfortable with giving out.

GOOD LUCK!

 

This is not complicated. Just follow the suggestions of @fotomoto, @TMR-JWAP, and @SFO. They know what they're talking about.

The whole purpose of unplugging the inverter pump connector is to verify that that is the problem, not so that you can drive like nothing's wrong. Just think about how hot the inverter would get as those little solid state transistors handle about 100 amps uncooled and you will understand why "short distance at low speed" means a few blocks at about 25 mph. If that. I would not drive it at all if it was mine.

@Kindke, I also would love to have some sort of manual mechanical override to disengage the parking pawl. But then some bonehead would run over their own foot or worse and sue Toyota. So, there are inexpensive wheel dollies that let you move all four wheels any direction you want.

 

Fatmatt86, are you the guy that runs his car until the low (no) oil light comes on then fills it up?
