Hit a pothole at 70. Car is in limp mode. Update: It’s the inverter.

C1259 and C1310 are brake system codes that flat-out mean there are hybrid-system trouble codes, and the hybrid system told the brake system about them. It seems we still need to make that information easier to find here.

"Wire harness or connector" are listed as possible trouble areas for at least several of the INF codes for P0A7A and P0A94. That's the kind of thing I might think of first after hitting a sir charles hole.

In your position, I would want to carefully follow the troubleshooting steps in the P0A7A and P0A94 sections of the repair manual, before deciding the inverter electronics actually went bad.

But you haven't identified your car exactly (though you posted in the gen 3 forum). If you were thinking to look at the PDF copy of the gen 3 repair manual that kind of floats around the web, don't bother, it's completely missing the troubleshooting sections for those two codes. The most you'll find there is the diagnostic trouble code "chart", which just lists all the codes with their INF codes and bulleted lists of what-could-be-the-trouble-area and what lights come on. Half a step up from totally useless.

So I'd have to recommend going to the source for the repair manual for your car, so the troubleshooting sections you need won't be missing.

Having a look at the underside might reveal something. Was it one side only that took the hit? How’s the wheel?

 

There’s a high voltage cable connecting to the inverter down quite low, just visible through driver’s side wheel well; maybe jarred loose?

 

Make certain you are using a scanner that can read the INF codes. Many of the trouble codes reported by a Prius start with the common headers you've already found, but are then followed by an "INFormation detail" which can substantially affect the way you should be troubleshooting any given problem.

Lots of popular scanners and diagnostic apps don't know how to read the extra details.

The Autel AP200 is highly recommended for this.

If you use a good code reader for full access and rent the actual repair manual from the link chapmanf posted you should do okay.

Good luck!

 

What this guy said.

 

The inverters toast meaning what it's not charging the 12 volt battery it's not charging the HV battery something? But the answer to your question you can go to places like LKQ and get one for $150 after 2013 should be the updated version of the generation 3 inverter with the updated parts for whatever the problem is with the 2010 through 2011 or 12 or something. You're 13 should have been passed that anyway whatever other junk yards not as big as LKQ might give it to you I used to have a bunch of them here if you were in North Carolina you could drop on by and pick it up but I threw them out I've been holding on to him so long this is how rarely they're used so I wouldn't worry about the three grand you don't have to do anything but pull your other one make sure the safety plug is out of the battery dropped the junkyard one in but the plugs in bolt up the bolts holding it down and let it rip The car will recognize it there's no handshake I don't believe or any of that silly nonsense.

 

Either buy a new one for around $2,200 or find a used one, then install it yourself. Keep in mind extra care needs to be taken since it's a high voltage component.

 

Repl w used

 

For DIY don’t buy used inverter unless it from low mileage donor. Most used high mileage.won’t last long enough before another failure. Buy new inverter PCB board instead, not hard to install, don’t buy used Pcb from fleabay either , most comes from repair shops or junk yards, high mileage or doa like 50/50

 

I'd check again. I've learned that even a car with a salvage title is covered under the settlement as noted in these Toyota documents.
