- Heyyyyy is that a HYBRID?
Yup, sure is! And it's a paperweight at the moment...
Owner has been trying to get it running for OVER A YEAR since swapping the knocking engine out.
PARTS CANNON HAS BEEN UNLEASHED.
Let's start from scratch and see why this Prius isn't emitting any greenhouse gases at all xD
First code is P0A84 - Hybrid Battery Cooling Fan Circuit...
Should be fun!

Plot twist, There hasn't been a problem the whole time, it's just hard to tell when hybrids are idling.
Toyota Hybrids don't idle. The engine starts all on it's own and only when the traction battery needs charging.

Dude it was a joke.
Do you realise how dumb it looks when you give a serious statement to a very obvious joke statement?
@@michaelslee4336 how am i supposed to know? I can't smell it from here, 2000km's away. So, whatever dude.
My comment still stands.
/end.
@@michaelslee4336 Yeah it's all good. A good joke (lol!), but a good answer too that will inform others that don't really get the theory behind hybrid vehicle psychology.
I owned one of those second-gen Priuses. Bought it at 145k miles, needed a battery soon after so I bought the $1000 kit and did it. Drove it 40k miles in a year. Really a remarkable vehicle, and easy to work on. Just a few extra caveats like being mindful of the high voltage, dielectric oil in the A/C, brake maintenance b/c the brakes are also hybridized.
Yeah Ivan, Can't wait for part 2 to show up here! This is really helpful for trouble shooting Hybrid car battery issues! Thank a bunch for
sharing your knowledge and your techniques for trouble shooting.
Ivan, I began watching long ago because of your wonderful demeanor, and I cannot stop watching because of your incredible intelligence and knowledge blended with persistence, and patience.
Bravo!
He is calm and super tenacious
Hi IVAN,this vid hit home. I have a neighbor I've been helping with a 2008 Prius,that has issues. 1st thing i said to him after going over and seeing it was,YOU NEED TO GET THE MANUAL or go online PAY WHATEVER it COST and get schematics for this thing.They make it perfectly clear if you fool with the wiring YOU MIGHT DIE!!!haha I can't wait to show him your vid,as you are the BEST at SHOWING and EXPLAINING thoughtful SOLUTIONS to the issues.Like you say and DO,many times PARTS are NOT required.like this fan thing,BOOM !!!that was the parts cannon going off.haha Another fan put in that WASN'T NEEDED.Your lessons are invaluable,thanks IVAN.
14:56 that's the infamous connector of "prius death". it very well known to have water leak in and make it a ships anchor. 🤣
as soon as you see battery cooling fan codes, that's an automatic primary target.
Alot of people dont know this but you can tow charge a very low hybrid toyota as long as the battery contactor closes and its in drive even if the engine is unable to start due to low battery. They warn people in the owners manual you can over charge a normally functional car if left in drive being towed behind a motorhome. The car has a pma brushless motor it makes 220v at 6 amps at 2k rpm.
Check the orange security plug at the hybrid battery, most times it is not correctly pushed in
AS you know the battery module consists of several dozens of single cells. Any one of those individual cells can (and do) become unbalanced. If the discharge is deep enough the cell(s) can go into reverse polarity. When that phenomenon occurs there is no way a system charge can provide or preform a so-called restore/recondition/et all. The only proven method to correct a deeply discharged cell is a charging process where each cell is treated individually with a special ac-dc waveform. This is exactly like any lead-acid battery where if the battery discharged so deeply as to allow a cell or cells to go reversed it will never again perform to spec (even though it will pass a voltage test, the capacity is severely compromised). Not saying this is the problem here, but something to be mindful of as you become more involved with these sort of vehicles.
Great thought process, Ivan! This sounds like a very interesting case study (expecting a few goblins at work inside)! Now itching for Part 2 🙂
Dunna-Nunna, nunna-nunna, Nunna-nunna, nunna-nunna, BAT FAN!!!!!
Argh, came here to comment this
Haha, Digging the title Ivan , Pain in the Priass 😮😮😮
Looks like another great weekend trilogy in the works.👍😀
A gem of a diagnostic, the prius vs the master tec. Bet you find a few bad cells in that so called new battery. Mine not only had a failed engine (piston rings broken/seized with carbon build up from valve seals failing) but cells needing regeneration with a Tynergy t180, that takes 24 hrs per cell see you in 6 weeks for part 2.
@chris dunkley Hi Chris! Whoa dude! Busted & seized rings & pistons AND a batten your flattery!
Is this destruction due to carbon build-up very common? Sounds VERY serious! Did you work out what caused it?
Does it REALLY take that long to charge the battery up? Sounds sus. Did you use an external custom charger like Ivan used or just the vehicle charging system? Am I gonna have to wait THAT long for part 2? That sux ass!
@@nevillegoddard4966 Ivan did a video of reconditioning the top end of a Camry, same as my Prius stuck rings etc. caused by burnt oil behind the rings from your guess is as good as any ones low pressure rings against the bore-valve seals turned to carbon-most likely crank case breather passing oil into the inlet tract and combustion chamber, all Toyotas seem to do this. The Tynergy t180 is attached to each individual cell as this is the only correct way to determine any that have lost to much capacity and can not be brought back from the dead so to speak.
chris dunkley Right. I dunno if I'd agree that ALL Toyotas are prone to this problem thiugh. Ivan has worked on one (a Metz?) with nearly half a million k's on the clock, so I don't think THAT one has a problem in this area!
Interesting re - the battery charger. The tynergy is obviously a balanced charger, connecting & monitoring each cell individually. I assume it can't monitor all 100 cells simultaneously, but only 10 or 20 at a time maybe? Is that why it takes so long to get the battery sorted?
@@nevillegoddard4966 Just + and - connections for one cell at a time, 38 cells in gen one 38 days @ 5 charge-discharge cycles per cell. Didn't use the Tynergy for balancing, just used a welding rod to join all cells together, all negs and all positives and left the pack to stabilise at an equal voltage,
Ivan did well to know when to move on, no ones going to make money on this heap to many problems.
Don't know if someone else has already mentioned it. But the way you get the engine to turn on is by pressing the throttle to full throttle and hold. They may do nothing because of the faults. But just so you know pressing the power button will do nothing to get the ice to turn on.
Has to say "READY" first :)
@@PineHollowAutoDiagnostics Understood. Just got the impression that you were trying to get the engine to turn on when you were pressing the power button.
@@PineHollowAutoDiagnostics Ready, Set, GO!
@@PineHollowAutoDiagnosticsthank you for this video
Where can I find info on the charger... I would like to buy it
I'm concerned about the aux battery at 11.8V. For a 12V battery, 11.9 is considered fully discharged. That may be too low for keeping the electronics happy for starting the engine.
I agree. He needs to replace or charge that battery.
This is another brilliant diagnostic video, problems identified & addressed, can't wait for part 2 👍
Ivan, man I really love the video you make it entertaining and I have learned so much from you. I don’t half understand some of the scopes you do but man it’s entertaining.
Sure wish I lived close to you - if I ever had a problem I would take things over to you. Thanks for the entertainment and great diagnostic information- you are one of few that do things right!
Aux battery 11.8v? NOT fine! You can get strange problems simply from a low 12v battery (in my experience)
Nice to see some progress, even if it seems slow. Nice that the fan is working. Just need to clean up the crusties on that connector and fix the broken wire, and wait for part 2.
Ivan is the safest shore for all the beached whales to land on ! :)
Nice almost bought one used when i was in NY state. Looking forward to part2
The Maxx charger is supposed to be running before it is plugged in to the hv battery . Just what the manufacture says. They also have an discharger to condition the cell.
Ivan, you've got us engaged now! Can't wait for part 2! Thanks for Sharing!
Seems like every hybrid I have ever had to diagnose, never had just one problem. At least the blower motor problem looks to be an easy fix. I'm looking forward the part 2.
Great video! I think you're being misleading though saying it's just hybrids, Toyota has been putting similar abs modules and pumps combined as one unit, dating back to the 01-02 4runner 3rd gens and land cruisers if I'm not mistaken and having to replace one in my 02 runner it was a $700 part used off a forum. At least they separated the two units on the 3rd gen. I believe they're a single unit on the 2nd gen Prius's as well.
Ivan, a Prius is not a beached whale. It's a beached Tuna Fish...
More like a stingray
Beached Electric Eel
Beached minnow
Codfish
Great troubleshooting! I find iit interesting that the owner finds that car interesting. I mean, I do too - as far as how it works, but I'd need to cover the car with some sort of tarp and work on the problems thru slits in the tarp. To each his own!
I'm the idiot who designed an engine for a car like the Prius 14 years before Toyota produced it. I still have a few of my drawings I tossed aside. It's not the first time I missed the boat.
I do hope for incredible wealth to arrive at Ivan's doorstep as I'm certain he will develop a winning mechanical invention.
LOL you got me again part 1 waiting for 2, interesting car Prius hybrid, very cool. Semi Flood car or water intrusion at a seal point.
Thanks!
Wow THANK YOU FRED 🙏🙏
I think batteries begin charging at high current & low voltage. As the battery gains charge, the current will decrease and the voltage will increase. So.... from what I saw, that black charger isn't doing what it should (unless it was in "battery analysis mode" when the video ended.).
I'm all in, and the part two message pops up. See you next time. Same Bat Time. Same Bat Station.
I used to work on an industrial estate where our work vehicle was an old 02 Prius. Thing had been a taxi. It had a wall charger and this somewhat dodgy setup with an inverter to run power tools off the hybrid battery. Saved us having to hump a generator or 30M of extension leads a lot of the time. You would be surprised just how much you can get in one of these. Its just a shame about a particular kind of sanctimonious people who happen to drive some of them.
Who would ever have thought there would be battery problems with ev cars in the wintertime 🤣🤣
I love your videos and great diagnostics. Diagnosing and repairing hybrid is so interesting. 10sec is just cranking time to attempt starting. Maybe faulty battery ecu. Looking forward to part2
If the engine sounded like it was running then stopped after 10 secs, the engine might not have actually started but you're hearing it being spun at idle speed by MG1, if no start, it will stop cranking after 10 secs or so
I picked up a ‘07 Prius for $400 with a missing cat. Of course Colorado adopted CARB standards a couple yrs ago so the only cat option was dealer at $2400. I found someone parting one out and got a cat for $300😊.
Well the cat ended up being aftermarket and sets a p0420 😢. Oh well, it’s still drivable and gets decent mileage and I only have $700 into it.
I wouldn't drive a Prius even if someone paid me 🤣 life is too short!
@@PineHollowAutoDiagnostics remember what jef fafa dunham says a prius sounds like going by...............
@@PineHollowAutoDiagnostics I might have a different opinion of you if you drove up in a Prius.
$400!!!!😂😂😂😂
This is a Beached Whale series! Great.
Styling aside Toyota know's how to make these cars and systems pretty good, I've seen more than a few with over 300k and still going, basic maintenance and all is well
Yeah unfortunately this one was a victim of neglect and abuse lol
Cannot wait for part 2... Great video as always Ivan.
Had this issue once with the same code. Replaced the battery ecu located next to the HV battery. Ran just fine.
OK! Thanks. A new info for me!
Ivan, I was wondering ( if you know) is the think tool based off the Luanch? Very similar screens. And do you find it better than the luanch in some ways? I'm really happy with the Launch products. I also noticed how fast the launch is with Fords.
The challenge is trying to understand all the logic induced in a hybrid electrical system.
To some extent the codes raised when something goes wrong are just based on the fact that a lot of people working with vehicles don't have a full grasp of the whole system.
One team is working on the battery charger, one is working on the drive system and a third is working with the rest of the vehicle. The third team is still in the combustion engine era.
Hi, Ivan, great video.
I would be very interested to know how they power the battery cooling fan with the added wires.
If they are simply providing another power supply for the fan, what is that power doing to the fan control box that is now having power applied to its OUTPUT?
Try looking to see if any faults disappear if you remove those extra wires.
See this all the time on the Prius Mk2, check the other block connector on the left hand quarter panel as the supply comes in on the left and runs down the length of the boot/trunk to to the right block connector. It too gets corroded, water ingress will be from cracks in the body panel adhesive normally around the roof channels. Awesome video as always Ivan 👍👍👍
Yeah, that’s a strange place to get green crusties
I am so afraid of these batteries exploding or catching fire with these home made devices. I am very interested to see part 2. So far so good!!
I think the chemistry is pretty stable on these older prius batteries
Interesting case study Ivan!
Oh it gets much more exciting 😄
I am not sure. Does it help to start car in service mode instead in a normal mode? In service mode would be posibile to run engine constantly and maybe to recharge battery?
Engine is disabled if there is a fault with the HV battery system 👍
Prius .. beached minnow (well, maybe a tuna).
that charger looks like a weatherhardened ATX computer power supply to me
Fun fact. A Prius will set a code if you run it out of gas. Customer had his Prius towed in 2 separate times because it died on the highway and both times it was out of gas a set codes for it
Sounds like the typical clueless Prius driver 🤣🤣🤣 please don't cancel me 😆
Man I love these vids
How did that connector get corroded? It’s not anywhere I would expect it to get water, acid, or soda spills.
I can already tell you its a fuel pump or delevery problem or spark. The 10 seconds of running is actually the electric motor cranking engine over.
When it comes to the Gen2 Prius (2004-2010 maybe?) you can always count on corroded wiring terminals INSIDE the car when you find weird scan tool readings! This was common in the Gen1 Prius too but the second generation Prius was NOTORIOUS for leaking rainwater into the rear of the car, then when you add in stray electrolyte vapors from leaky NiMh cells mixing and condensing all over things you get very "interesting" fault codes that are hard to pin down. But I knew you would come to that conclusion eventually too. It was fun watching you sort the issues out. Brings back old memories for me! Thanks.
One of those cells was flipping between -15 and +15 on the monitor.
Very sharp observation! This is where Part 2 is going :)
Battery voltage seems high. The system should be 201v nominal. And the batt ECU wants 60%- 83% max state of charge. It needs room for some Regen charge. I think 218v should be the max voltage of a fully charged pack at rest.
This part 2 malarkey has gone on long enough now 😢😢lol
No worries this Prius has enough issues for 7 parts HAHA
@@PineHollowAutoDiagnostics 🤣🤣
@@PineHollowAutoDiagnostics 7 parts? Well, at least you'll have time to charge the battery.
But, but, but, Scotty say’s “It’s A Toyama, what could possibly go wrong”?🤔😳🤔
Ivan: This is a blower motor resistor controlled by a pulse width modulated signal.

I would call that one a beached guppy.
I agree w/ you all hybrid cars out to have the capability to charge at home
Always a cliffhanger, lol!!!
Another odd idea with these eletric vehicles. It's supposed to be able to be charged from house current so it'll go up to 15 mph on the battery then the gas engine takes over and apparently charges the battery a small amount until house current is hooked up again. Well, here this battery is low and it is disabling the engine which is opposite what it should be doing I presume. It doesn't make sense that the electric motor battery has to have a charge to start and run the gas engine. Regardless of the electric motor battery state of charge of low or very low, shouldn't the gas engine start and function? As it is now, the electronics think the battery has voltage and is forcing the vehicle to use the electric motor which can't start because the volts are too low. Obviously the green crusties are throwing a wrench into the operation process so there's got to be more of them along the way in the wiring I'd say. Once that car is fixed, I'd through in a can of Deoxit in the glove box !
This model Prius isn't plug-in. Only the Prius Prime is plug-in.
I don't think these have a 12V starter, they use the motor-generator to crank the engine from the HV battery, so if that is disabled the engine can't start.
Yes, understood. Too bad Toyota made this model that requires the electric battery to run the vehicle 100% vs. their other model, that will.
And if the bat fan fuse is OK check the rob in fuse next😁🇨🇦👍
SOLUTION ...Orange Plug on side of large battery has two separate actions ..1st action connects the battery ....the second action pushing it DOWN connects an interlock
Part 2?? Ya got me all excited for the big finale' lol.
Ivan, aka Captain Ahab of mechanics…..chases the beached whales not because it’s fun, but because it’s what he was called to do. I can’t wait for the Novel that pairs with all the videos! 🤣😂
Hallo Ivan , there is a connector right side behind the plastic. Please check this one .water drain into
10:35 Why do you use a piercing probe here when the copper of the wire is exposed anyway about a cm away?
Personally, I think we are missing the boat by not owning these cars. I think we should sell our 27-year-old Mercurys and get some of these. I think we would come away with the satisfaction that we helped the environment, saved tons of gas, and got excellent traction in the snow. Clearly, if this guy has owned 20 of these cars and is able to make a hobby of repairing/selling these then obviously they are VERY reliable. Kilmer says these cars have something called an Adkinson Cycle powertrain. I have no idea what that means. The biggest problem with these cars is I would need to bring it to Pennsylvania Furnace to get it repaired. Great video!
Reality check, I owned one (of this second generation) and it had very poor snow performance on all-season tires because the traction control is so aggressive, as I understood it to protect the electric half from over-revving or something like that. I was once on a hill and the car refused to move up it because there wasn't enough traction. Had to turn around and go back down.
@@yitznewton Reality check, everything I typed is sarcasm.
@@lvsqcsl🤣🤣🤣
@@yitznewton get some snow tires!
@@PineHollowAutoDiagnostics A front-wheel-drive car that does poorly in snow? Go figure.
I saw some bad cells when you were scanning
Ivan it’s a bad bcm inside of the battery
I've seen that wire broken on every Prius that comes in with that fan voltage code. It doesn't seem to be water intrusion, I think the connector is inadequate for the amount of current it carries over a long period of time and it just fails. Maybe the hybrid battery is low from cranking an engine that won't start. I've heard that if you erase low battery voltage code you can get a few cranks out of the battery before the code resets and disables the start function, unless it's really low. Never tried it. Hybrids are still a learning experience.
Wire corrodes because it's B+ ALL THE TIME and is not insulated at all from moisture 😅
@@PineHollowAutoDiagnostics Hi Ivan I dunno if having b+ on it all the time accelerates the green custies does it? I thought that just the chronic, persistent moisture on the brass terminals would do that? - Especially salty moisture.
Anyway how does the moisture get into that connector in the first place? It may be a common problem from what some here have said. Almost a built-in problem from the factory. Hopefully there's an easy 'walkaround' so that this problem never happens again
@@nevillegoddard4966 green crusties is a chemical reaction driven by electrical potential. 90% of the time it's a B+ wire, 5% it's a ground strap 😁
@@PineHollowAutoDiagnostics Galvanic corrosion correct? From different types of metal in contact and power going through accelerates the problem.
@@PineHollowAutoDiagnostics Oh right! I have come across the green crusties a few times, but obviously not as many as yourself.
I have successfully used salt & vinegar to remove them from corroded brass terminals, but they had only surface corrision, & had not completely rotted out! You have to be able to completely rinse it away afterwards of course.
It doesn't look like the 'de-oxit' needs to be rinsed away then?
Camry no start after water puddle....hybrid 2015..... Won't crank over by hand at the crank pulley either..... Not sure the connecting rods are broken
have you checked the battery in the key-fob... 😱👀
Nana nana nana nana nana BATT FAN!!
Bam pow
Cool ivan🤏🏻
Ivan, would it be a good test to put a light across the legs of the fuse holder to see if there was a load on the fuse holder when the ignition is turned on ?
That's a valid test... But wouldn't really help...
@@PineHollowAutoDiagnostics I thought a little earlier in the testing perhaps………
ANOTHER GREAT VIDEO
Great Video ! I wouder if we have no parts required it part 2
Finally got my favourite tech on a my favourite 🚗 car.waiting for conclusion 👌. Cheers and good luck ivan.please link me to this wall charger system. Please
Why don't they use the 12v battery to help charge or jump start the engine
The regular 12V battery only runs the computers
How did the owner build the HV battery charger?
You get all the "no starts"
...statistically impossible lol
Probably just needs a fresh batch of AAA batteries.
The Delta SOC value is a little concerning
GOOD VIDEO!!!
I'm gunna throw a wild guess out and say the homemade charger isn't charging through the on board current shunt so it's not going to know when you are charging and it's getting confused
How does a connector that high up get corroded? Was this car under water?
Interesting case. Is this guy from the Scranton area?
Can't see a reason for the fan in the charger to run when "off".
Wow, prius! I hate those things lol!! I don't like hybrid stuff. Too many unknowns there! I know nothing about this lol. Great video!!
Have you ever worked on a Datsun Leaf?
No 😅
👍🍻
Oh boy, looks like this is going to be fun Ivan! Reminiscent of a college engineering senior project. "Your mission is to figure out this bundle of wires that were submerged in salt water and doctored up by a kooky tinkerer, clean it up, re-wire it back to what it's supposed to be, and get this "beached whale" running again."
I wonder how the connector got so bad? What was the car used for?
I have one of these. They are known for water leaking from the rear hatch seal and it fills the 12V battery well with water, so everything is damp back there all the time. I'm going to replace my 12V battery ground cable today because of corrosion. Mine has 246,000 on it ATM.
i bet it was never running for 10 seconds, just turning over for 10 seconds they sound like they are running but aren't.
Was it towed in by AAA or just AAA batteries.😀👍
Towed by a Tacoma on a really rusted homemade trailer 😂
