- In this video I show how to diagnose a bad hybrid battery in a 2004 prius. This process would be the same for all 2003-2015 prius's.

Bro....thank you, thank you, thank you. Potentially $30 for a module as opposed to $3500 for an entire pack is a huge difference. Thank you for sharing this man
You must be getting rip off if someone is offering you $3500 for the whole pack. Cause each module is only $30 on ebay. Times that by 28 is only $840 to replace the whole pack. So why the fk would someone offer $3500 when it cost only $840 for the whole pack. Lmao
Because it's an entirely new battery not just the modules
$30 vs. $3500 is a big difference? Are you sure?
The most helpful tutorial on the red triangle of death I have come across so far! Thank you sir!
Recently changed over one module that had a reading of 6.38v . Very easy to remove the battery just make sure you are a capable person to do the job.
thanks for the tips, im currently dealing with this issues after having my pri for only 3 months and is helping me out alot
This was great, thank you! Looking forward to the tear down and test video!
Part 1 and Part 2 were recently uploaded. I am planning on a part 3 showing some data on fuel efficiency, voltage difference, and the end result before I sell the 2004 so stay tuned!
You all probably dont care at all but does someone know a tool to get back into an Instagram account?
I was stupid lost my login password. I love any assistance you can give me
@Ameer Rocco instablaster =)
@Brodie Nico Thanks for your reply. I got to the site through google and Im trying it out now.
Seems to take a while so I will reply here later when my account password hopefully is recovered.
@Brodie Nico it did the trick and I now got access to my account again. I am so happy:D
Thank you so much you saved my ass !
Good lookin out def checkin out your other vidz
You’re the man thank you
@ H-EV TECH. GREAT videos! Question thought. Do you know if the cheaper scanner be compatible with doctor prius? Will it show the voltages for each pack?
Nice EXPLANATION! Quick question!!! If you have 2-3 damaged cells, how long should you use the car (prius 2007 in my case) before fixing the problem? I am thinking of buying a used hybrid battery in better condition instead of replacing the cells.
Using bad modules puts unnecessary stress on the other module in the block. Ideally if you have 2-3 bad modules, you get it fixed ASAP to prevent further damage to the pack. The 2007 Prius battery I retrofitted had random complete engine shutdowns because it could not keep the 12v battery charged using the DC-DC converter.
@@HEVTech1 that’s what mine is doing now as well
Hi, thank you for all your knowledge ! Does this OBD reader work w an iPhone ? I'm nervous about buying the wrong one.
3:00 loved this part. Thank you for explaining. Is this the same set up for a 2014 Prius C, 3?
Thanks bro.. the problem solved
Thanks ...wondering how to count moduels on my gen 3 ? Is block 1 closest to electronics?
If the modules are being checked with the multimeter voltage section and if its showing 7.40 v average in those , can we assume reasonable okay battery ? Pls reply some experts here
Hi bro thank you for sharing about the battery repairs
I would like to see a video of how to purchase these modules in Ontario Canada or recommend an option to have this work done in Buffalo Buffalo New York
Thanks
I have a 2001 1st Gen Prius. The link to the OBD Reader on Amazon says it doesn't work on Hybrids. What would be the correct Reader to use? The main mult-module battery was rebuilt/bad batteries replaced about 7 years ago. I'd like to check if any of the battery Modules or individual batteries have gone bad. Thanks
yeah dude you're awesome..
Have you or anybody here in this comments section ever thought about replacing the battery bank with a capacitor Bank to supply the necessary initial current and voltage to start and drive the car we didn't exactly get as good mileage but anyway
Note: "This product is not compatible with hybrid or electric vehicles." This statement is in the "Key Features" of the OBD Reader you used in the video. So Should we buy the "cheaper" model or the one you used in the video?
With my gen 2 the red triangle is on but the car in the upper left hand corner is green. It's a 1 year old rebuilt battery with new cells. The battery shows 14.3 volts on the screen. Any idea's?
2006 Prius 295k mls. the light came on, I continued driving and everything except doorlocks, hazard lights and headlights were dead. Towed to mechanic. Do you think the hybrid cells are the problem? Do u think it may start with a jump? Just to see cell activity on Dr. prius? Maybe its time for a newer car.
When the engine is turned off? 1:25 I have all jumpy blocks but when the engine is turned on they seem to balance and start to be equal. I wonder is it good or bad.
Thanks for the video. Any recommendations on where to purchase modules?
I got mine on ebay where there are many reputable sellers. All the modules on eBay will be used, but the goal would be to replace a dead module with a module that isn't dramatically better or worse than the modules in the rest of the pack.
How did you found out that you needed to replace 5 instead of the 2 modules 9 and 11? The other ones looked OK on the Dr Prius.
Hello thank you for your video.I have prius 2 nd generation.The Problem is when i go to the gass station when put the fuel to the tank of car it's reject.(by the sorry my english)and also the fuel gauge shows in correct what should be reasons?thank you
It take a few minutes for the gauge to settle in. Then it reads properly. If it still does not, you may have a bad fuel gauge in the tank.
I believe you said the car has 240k miles, what's mileage, would it be less after time and adding a new block?
Ty
I got the red triangle of death, but my battery shows almost full. My mileage has been great lately. I don't have the Bluetooth thing, but I'm going to download drprius app after this video. It Any ideas?
my 2004 has triangle and split car picture/it starts - then engine revvs - transmission engages but slips like its try ing to slightly move and it does- but not enough to drive it ANY HELP ?? SUGGESTIONS
Blocks 7 and 9 on my battery are bad. Does it seem like the modules towards the middle are commonly the ones which become problematic? Is this due to the middle being the hottest area of the battery?
Yes the middle of the pack tends to be a bit warmer and those modules usually fail first.
yes
Best video on this subject so far, but the guy needs a tutorial on how to hold a camera steady. You can get sea sick watching this.
Appreciate the feedback! Certainly one of the drawbacks of using my phone to record. It can only get better :)
Question: how to get the car to run/reset if it shows you those two icons (car with exclamation point on screen, triangle with exclamation point on dash)
You can use the free "Torque" app to clear the vehicle trouble codes and it will then attempt to run and only throw the warning/code if the same error threshold is reached.
@@HEVTech1 thank u. Do i need to buy any hardware?
You would only need an OBD2 diagnostic tool (I linked mine in the video description)
My Prius has 478000 miles I gotta get to 500! Lol
Can you drive a prius without the hybrid battery? My uncle said the smaller battery is what starts the car and the car will go from 2 to 1 engine meaning less power and more gas needed but car will still run while the car dealer is saying you need a hybrid battery to operate the vehicle.
The 12v battery only turns on the inverter then the entire hybrid system including starting the gas engine is powered by the hybrid battery. You cannot go anywhere without a functioning hybrid battery. You can "limp" home with a couple of bad modules, but the car can also suddenly lose all power so better safe than sorry.
@@HEVTech1 I saw a video where a guy is driving prius with dead batteries. He also said he bought them with dead hybrid batteries.
@@Aria-Invictus I drove this one home with the bad modules. It ran great for 20 miles lol. There is no guarantee it will stay running when the hybrid battery has bad modules. It won't typically lose all power but it absolutely can and did to me.
There's no alternator in the Prius so it might run with a dead HV battery until the 12v battery is duscharged.
Where can I get the cells to purchase ?
Which software you are using?
What is the OBD2 you use?
hi i have a customer with a 2nd gen prius. With a completly dead high voltage battery. And a dead 12v battery. According to the info center the high voltage battery is completly flat. Im pretty sure this will cause it not to crank even after replacing the 12v battery. I wanted your feedback
That is correct, the HV battery is what starts the car.
Any way to know if the generator is gone or going.
Where did u order the modules from? Amazon?
I got them on ebay from a reputable seller.
Dr prius works only for priuses ?
hi i have 2gen anniversary Prius. so had problem. drive through error came (VSC/Trangle/(!) ) main display left coiner show Red car. after error showing few second drive through gone the READY & cut off engine. my garage fellow repair the hybrid battery & do the engine turnup but after 2days came same problem. plz help me solve it
I think it's the PCM
Video on gen 3?
what if it is scanned and then the scan cannot be connected to the vehicle.
What is you OBD reader?
ODB LX I just put the link in the description.
I have an OBD reader, do I just need to download a particular app?
Drprius app
omg this is exactly what it’s going on wrong at the moment with my prius toyota2007, however the mechanic has not really diognosed this problem at all. It’s frustrating
Hi, which app you are using? Thanks
Drprius. I am about to download it and try to figure my red triangle out 😁
When POOA80 comes up, it says the HV battery is overheating but it doesn't say the cause. Could it be the fan, or resistance in the lugs connecting the modules together, or something else?
I know sometimes the battery cooling system get clogged over the years. You might want to blow it out and clean it and make sure the battery cooling fan is still working.
@@travisb1757 I don't know why I'm not getting an alert when people reply, thank you. Oddly enough, there doesn't seem to be any dirt or dust anywhere in the system. Fan is clean and spaces between modules are clean. My 12v went dead within a year. I really hesitate to bring the car to the dealer. I don't trust them to even change the oil. I've got a mess on my hands.
And where can I get good modules from? The latest thing is to load test them. Not just check the voltage. I didn't do that when I pulled the battery apart.
I prefer using a cheap meter from harbor frieght.
Main voltage.
Then each module.
So I Changed the bad cells but when I turn my air conditioner on it charges in the purple but when it’s off it’s in the green? I don’t know why my lights are still on after changing the cells. Help!!!
If you only changed out the bad modules without balancing the voltages between each module you could still see warning lights on the dash.
Have you tried clearing your trouble codes via the Torque app?
@@HEVTech1 how do you balance the modules?
Do you have videos on that?
Or reconditioning?
Love your work here so far btw
..thorough and simple
@@HEVTech1 Do you have a video about clearing trouble codes via the Torque app and where/how to get/connect the Torque app?
I have a Prius and it has a break light on the dashboard, a beeping noise and the brake is hard, does anyone know what it could be?
I don't think you can check hybrid battery with 0bd2 scanner
Great video, but my ears kinda hurt from hearing you say “ODB”...shouldn’t it be “OBD”? ;)
Yep! lol part of getting started on CZcams :)
it is ok to drive the car when those signal are out ?
I don't think it will be a good idea
Hi
My 2005 Toyota Prius gives out warning lights (Engine light, VSC, and the RED TRIANGLE light and also a circle with a Exclamation Mark ❗️ in it), only throws out those light when I am driving on the highway for long(after 100km at a average speed of 125km/h). The car drives fine all the time, the light goes off after a day when the car drives in the city normally.
The warning shows that "HV System, Hybrid Battery(electric motor, inn Barter unit, Baku battery, ECU, etc."(this was translated to english using a translation app).
Please could someone help me how I can sort this issue out, I think the battery starts heating up, but thats just my assumption.
Thanks, please help
Mine is doing same thing - did you find out anything?
Mine is doing the same. Someone comment if they’ve found any success fixing this.
@@brianrogne2912 did some research, could be the battery fan in the trunk. Or just needs a coolant change.
Theres actually a video of how to do those. Just search.
Havent done myne yet gonna do it now.
@@DerrickLorah replied
@@arbaazkhan2878 Thanks! Mine ended up being an Inverter Water Pump Failure. Code P0A93 on an OBD reader.
08 red triangle says wiring problem in main harness
Nice sales pitch.
"Red Triangle of Death"? NOPE.
It's the Master Warning Light" that alerts the owner to possible problems in one or more of the car's systems,
Really not death I read they run fine without
Sure your not getting 55 a gallon but it still is ok
Eventually you will run into significant issues. On this particular car, it would lose all power (to absolutely everything) and die while on the highway - not ideal...
@@HEVTech1 mine is doing that right now…
But I’ve got the 12v tested and know it’s bad..
What do you recommend?
Anyone ever repair a hybrid battery with a delta soc of 34%?? Currently on my tear down and each module is between 6.8 and 7.3, bus bar plates are extremely corroded, so going to clean those, but never saw anyone doing a repair on a battery with such a high delta soc...
How see rhe percent life
I wanna if this car have start
WTF, you have potentially two 1.2V batteries that are bad and you get a red triangle of death??? Is the car's performance real off with that low of a %. I mean that's basically 1%. Or is that the whole block is seriously affected and therefore you lose those two blocks? Could you explain this a little further, I'm considering buying a Prius? Thanks...
Your Internal Resistance graph should be poppin also.
Do i need wear gloves i need change connector s
Just put new battery the little. One

How about putting some gas in the car. Lol.

My car was clinking and drove like 20 miles more and turned off do you guys think it's the battery or the engine?
