Toyota Prius Gen3 2010 - 2015 inverter replacement

Thank you sir for helping me change out my inverter converter on my Lexus CT200h. Its the same as the Prius. You video was perfect.

Perfect video, thanks man! Just replaced my old one with one from a salvage yard....only issue i had was the fuse for the A/C was blown in the salvage inverter so I replaced it with the one from my old one and my A/C was good to go!!!!!!

[@igorrosales1799]

Hi I have the same problem, where can I get a salvage yard inverter? And how much it costs average?

[@alan6832]

@@igorrosales1799 I'm seeing a selection on Ebay in the $300 to $400 range. I think the maker should still film himself disconnecting and reconnecting the batteries and also draining the coolant and splice them into this video. It is missing important steps and it looks too easy as a result.

[@rh63892]

If you have a 2nd gen and new prius and your inverter failed, check to see if there is a recall on the firmware. Mine failed about two weeks ago and I did just that. The dealership repaired it for free because it was associated with the recall. Mine was a 2012 Prius with 115k miles, Hope this helps.

Yes .. you r right...unfortunately this software update came after i made this video...

hi thanks for the tutorial, is 8 wire horness bolts longer than other inverter bolts? just replaced my old one with new from a local store and i'm so confused about bolt locations, also replaced inverter water pump that was very hard job, only water pump left that has to be replaced on my gen 3, seems to be pretty easy.

[@noelabela9283]

Hi thanks for the video I have a Prius Gen3 and replaced the hybrid battery in 2021 and now I got the same message 'Check hybrid system' and the error is showing DC converter performance. Does this means need to replace the inverter? Thanks

[@CtRacerX]

Yep, the switches on the inverter went bad/ burnt due to the coolant either not circulating well or because the fluid was contaminated. Definitely check the electric water pump, and put in a new (used) inverter

[@kumara5492]

Nice video. I am here to see how I can move inverter so that I can have access to replace inverter pump ( as part of maintenance on my Prius V 2013 with 190,000 miles ). So, is there any other better way to replace the pump from below or from the side ( removing headlight assembly ) without disturbing the inverter so that I need not have to disconnect orange hybrid battery safety plus for this process. I am afraid I might have to deal with some codes after reconnecting the orange safety plug. Does it usually throw errors after reconnecting the safety plug? Thank you and I subscribed.

[@user-mx4et6mn3u]

From my understanding you have to remove the inverter to get to the pump.

[@pydepiperproductionsllcjon7585]

You can replace the inverter pump by simply removing the right headlight. You do not have to take out the inverter. It takes about 15 mins removing the headlight. You disconnect 3 bolts to losen the bumper, then 3 bolts to remove the headlight.

[@brgo_1787]

Yes I think you do bro that’s what I’m noticing rn. Not to bitch or anything but everyone who has made a video changing an inverter they don’t say if you have to drain your coolant but it’s always empty in the videos

[@bartbiniecki3711]

Very Nice 👌 Thank you!!!

[@jhill4071]

Any recalls or TSBs on this Inverter. What was the criteria for replacing the Inverter? This is a highly reliable Toyota product and this an extremely expensive component. that's not known for failing. One should get a test/opinion from a second Indy shop to see if thire $20,000 test tool confirms the malfunction/replacement need. Then the question of where did the replacement Inverter come from because it sure doesn't look like OEM with a warranty.

[@Themechaniclife24]

Eventhough this unit rarely failed but it is not failed proof, they will go bad at some point. Replacement is depending on ur budget.. u can easily get a reman or used one from a trusted source since they r highly reliable for a fraction of a brand new one from toyota.

GET IT DONE AT THE DEALERSHIP THEY REPLACE INVERTERS FREE IF YOU HAD THE RECALL SOFTWARE UPDATE BEFORE

[@janepaulhutson7426]

Well this is about as straightforward as you can get. So why does the dealer need the car all day + with huge labor cost for what can be done in less than an hour and no need to jack up the car?

[@ohhwhen]

Because most Toyota dealers are dishonest. From sales, service and especially the repair bays. If we could record what they hide back there, they would not be in business. Great vehicles, but the North American Dealers on the west coast have a lot of issues.

[@vintess7779]

Great, informative video! I have a quick question. I had the 20TA1 recall software update on my 2014 Prius Four performed. On my way home, I noticed that the traction battery charge indicator was a tad higher that about the 25% charge level AFTER getting home from the dealership (about a15 minute highway trip). Prior to the the update, the battery charge indicator was never that low after a highway trip. After the car sitting for weeks, while I was on a trip, and after recharging the battery, I now am getting a "check hybrid system" note on the display. The care won't go into drive or reverse and the steering wheel is as stiff as a skyscraper I-beam. In other words the car can't be driven! Other than this, all other car functions seems to be working fine. In your experience, does this sound like an inverter issue?

Hey do you have to drain the coolant to do this job ? I see that your coolant was empty

[@JS-hg4vj]

I am not sure on Gen 3 but I know on Gen 2, there a cooling inverter, most young mechanics just top off cooling but if your doing it yourself do it the right way. Bleed the cooling it takes 20 minutes and pretty easy to do.

[@Trading_sos]

Great vid! I am right now with my 2010 in the driveway, it was turning the dash on and saying "Check hybrid system" The repair man disconnected the orange plug on the back and nothing. He said it needed a new inverter, he brought a refurbished and installed it and now is giving P3004 and still wont start. He didnt remove the air filter and we havent put new coolant in, but not sure if that could be why or the problem wasn't the inverter in the first place. Any idea 😫?

[@kumara5492]

So, what was the problem ? Is it water pump that's not working ? Thank you.

[@vintess7779]

Hi Jay, Did you ever get your car going? Before you decided to replace inverter, did you have the high voltage fuse checked that's inside the inverter? I have a 2014 that has that dreaded "Check hybrid system" notice just like you reported. Of course, I did a stupid thing like hook up a battery charger with cables reversed and that started this whole nightmare!!!

@@raymondgonzalez4521 just call Toyota USA and give the VIN number. If it is part of the recall, they will tell you how to get free inverter. If not, you can ask that you have problems that most likely related to the recall/campaign from NTHSA website. Or you can call local dealership to help you getting new inverter. Dealership often can help for such case and they will get the money for the labour without paying anything for parts.
