Although this is a good way to see what the resting voltage of the 12 V battery is, and also shows if it is being charged, this has nothing to do with the Hybrid driving battery.
thank you so much! going to test drive a prius next week and this is very helpful. truly good video and thank you! happy new year! Cheers from California Austin
thank you my friend! Glad this video helped you out.. The prius in this video is still on the road and getting 50+ mpg. BTW I've got a couple other great prius vids on tis channel you should check out. Good luck and let me know how your test drive goes.
Note, for UK models, the button labels and positions are different. I had to press the CAR button and switch the lights on and off 3 times to get to the diagnostics screen.
thank you so much for doing this. i just bought 2 cars (one for my wife and one for my myself) and this was my biggest concern. now i have a way to check.
I appreciate this video. My 2007 has 236k miles with the original batteries and came in at 14.0. Hopefully I can get through the hot Florida summer and make it to this time next year. Wish me luck.
Keep it in the garage if you want to safe your HV battery longer. Heat is the main problem for hybrid battery. The 12V battery last about 7-9 years in Florida without garage and the HV about 10-13 years.
True, since the motor battery is a high voltage one(can't remember if 300v or more, or less on the 2nd one) and there's a buck converter or transformer somewhere.( i vote for buck with a coil).
Ya. Because don't alternators run at 14.4volts while charging the 12v aux battery? I believe there's also another trick to view the battery level by pressing certain locations on the LCD in info mode. Something like that.
Sorry, but this is not a good test of the hybrid battery because the prius 12v battery is very small (Amp hour capacity) and it only takes a few amps to push a fully charged 12v battery up to its full charge of 13.8 volts. The hybrid battery in the prius has to send 100s of amps to the motor when needed for traction
It is a good idea to make notes of these procedures and keep them in your glove compartment. I got in my car and drove off and notice that the digital clock and the radio presets had reset. I did not check anything out and later, when I had gotten to my destination and then gotten back in my car I had a dead battery. The cause was the 12V battery ground connector had come off completely. When I reconnected it I had to give it a jump with my little battery pack and I was off. I should have checked everything as soon as I noticed digital clock resetting. It does not just happen for no reason
yep, very useful tool when you have a prius. THis will tell you the hybrid battery voltage and the 12V AUX voltage too. and you will see it change as you drive to check if the charge output is good.
This is the auxiliary battery not the High Volt one. The 14v when in Ready Mode indicates that your 12v battery is accepting a charge and that your inverter works.
Another way to get out of the diagnostic check mode without turning car off is press and hold display for 5 seconds and let go it will exit out of it 😃
The "battery" shown on the Info screen is the 12v I am assuming. Is there a way, when driving around to recharge a jumped 12v battery, to visually tell if you have driven your car enough to charge it? Some say 8 hours driving. I can't drive for 8 hours.
FYI - The test you show only verifies the 12v Aux battery, and the vehicle's alternator. The diagnostic screen shown does not provide any feedback regarding the traction battery which should be in the region of 346v (comprising of 96 Lithium cells in series of 3.6v each).
hello my friend! Thank you for this great information, you're correct. This video is only intended to show the PRIUS SELF TEST diagnostic screen. It will show you the actual 12V battery levels in real time, and that is the purpose of this video. To test the hybrid (traction battery) there is no way to do that with any on-board equipment without other external equipment.
Great video. When I start the test volts are 12.4 then when I start the car it drops to 11.2. Goes to 14.2 once if completely starts and is in ready mode. Is the drop to 11.2 a concern?
My catalyc comverter got stolen on my 2009 prius.. I drove like that for less than 2 miles and got red triangle with exclamation point on it. When that happened car started to loose power and eventually died on me:( right now I have it at a muffler shop where they will put another catalyc converter on but car still does not turn on..when I press on power button all the lights come on with rd d triangle like if car it's on but engine not on. Lights, radio and power windows work . The windows are slow though so I don't know if battery it's dying. If I remember I have one purple bar. Also keep getting a message about something that car needs to be on flat surface and something about the transmission . A while back it completely died on my while I was changing the passenger mirror, after I was done I gave it a jump and everything was good. This time it won't move from one purple bar even after a jumped it.
hey man! The Prius Cat Converters being stolen is a real problem now. I have friends who had this happen to their car too. Reality is, these cars are so good and last so long that parts are highly desirable. You don't see anybody cutting parts off a KIA, right?? lol. Anyway, it sounds like your Gas engine is not kicking in to charge the pack because you're missing part of the exhaust system. Once it's replaced it should go back to normal.
Yea it's crazy. This rides are hot right now. To replace the part here in california is close to $3000 cause it has to be straight from dealership cause of the Cali emissions laws:(
Here in Pakistan we get only used batteries for replacement. I had code p3000. So I got my hybrid battery replaced. When I used the method you described. The battery voltage are 12.1 but after turning on the car on diagnostic mode the voltage dropped to 11.8. Hybrid battery display screen also shows sudden drop of bars from blue to purple sometimes when I stop the car for few minutes. And on two purple bars car keeps running for many minutes but the third blue bar takes alot of time to appear. Its not happening always but randomly. Can you give your expert opinion whether the battery is good or bad.
hey buddy! These cars do not have an actual alternator. What happens is after the initial few seconds when the 12V battery starts the car's electronics, the Hybrid Drive battery kicks in and takes over, that is where you're seeing the 14+ volts come from. Not the alternator really.
My only problem with using this method is that the central display sometimes doesn't work. It will go off for months at a time (no consumption readout, no radio, etc.) and then start working for weeks or months. Dealers and specialty shops won't try to repair (it's obvious it's a faulty connection, but I realize it could be a bad solder on a chip, which would be ridiculously time consuming to find) but will only replace it at quite a hefty price. Trying to keep this car running, since I'm now retired.
hi Diana! I know exactly the reason why you're having intermittent DASH light problems, this is a common issue in all older prius cars. It's called the combination meter malfunction and results from a faulty capacitor in the dash cluster. Very pricey to repair. There is only one easy and reliable (but temporary fix). In the trunk you will find the regal 12V battery (not the hybrid battery). You need to disconnect a white wire that clips into the battery for 10 seconds. This will reset the car's electronics once you reconnect it and the dash will light up. Often times this happens in the cold, but it's a 100% temporary fix.
There is a video on TH-cam I believe that details the MFD repair. Search for 2nd Gen Toyota Prius Fixing the Multifunction Display and Combo Meter There are other videos as well, though if you have the time and are willing to learn and do, is a cost effective option.
This video goes more into the MFD since sounds like the issue if not only the connection. Video titled DIY Prius Gen2 dash Instrument cluster and MFD repair 2004-2009. Problems I encountered shows some extra info.
@@dianadiehl I'm going bonkers trying to find the best video I've found detailing the change, though might be on a website the more I think about. This ones good as well, 2004-2009 Toyota Prius Repair MFD Digitizer though I need to get back to what I was working on. Have a good one.
Hi Thanks for your clip. My Prius 2007 red triangle is on now . How can I diagnose that please ? I just want to know is it because of 12v battery or hybrid battery? Thanks.
My battery shows 90 to 100% in the morning, and when I start driving, no further than 2 blocks, the Battery drops to one bar. And then slowly builds back up. But lately, it started doing it right after I get off work. The battery gets down to one bar all the way home, for 42 miles. My gas mileage is bad 38mpg. I installed some cheap injectors, and my mpg went to 48mpg, but I got a check engine light. Then, after almost three months, I went back to the old injectors bc the car had some misfiring issues when the car was coming to a stop. I suspect a dripping injectors so with the old injectors, the misfire dissappear but the bad mpg came back.
In Toyota hybrids the 12V battery is charged by a DC-DC converter in the inverter assembly. That is why the battery voltage came up when the system went ready, and will eve before the engine starts. No alternator or starter on them.
Quick query: “To check the hybrid battery, turn the car on…” i’m confused here because I thought the car was already on and nowhere in that particular section does it say to turn it off. So how do we get from testing the 12 V to testing the hybrid? Your car appears to show the display illuminated whilst the car is off which I’m confused by. Someone clarify for me please?
Thanks a lot for video. It was very useful. I have one trouble with Prius 2006. Abs module seems like bad, but the dash board is coming on and off. When abs is working dash board coming on. If you know something can explain what is the problem ?
hey buddy! these cars sometimes do have an issue where the dashboard does not illuminate. You can get it to light up by disconnecting the 12V Gel Auxiliary battery in the trunk for 10 seconds. It will reset the dash's capacitor that powers the dash on. Its a weird system, but older Priuses (including mine) does this sometimes.
hey buddy! What do you mean "hidden camera option"? Do you mean the backup camera in this car? This trim level has a back-up camera, some model cars do not (typically the lower trim levels on 2006 and under models).
hey!, love your comments, motivates me to come up with more car video topics. So is your brake light on in your car? This prius actually still has it's original brake pads and rotors, even at 145,000 miles. Incredible, I know. Never worried about brakes. I can probably get another 40K on the current brake pads.
@@hybrid32494 My Prius had the brake pads and rotors changed at the 62 000 miles. The dealer recommended to change it every 38 000 miles. But it depends on how you drive. My car doesn't have the brake light ON but the pads make noise when i brake.
I cant believe you went through your brakes so quick, do you not use much of the slow regenerative braking techniques? You should try to visually check the amount of brake pad material still on there, it's possible that the pads are actually ok, but the slide pins are rusty and they don't release the brake pads back to their normal position.
I have a question, I have 2005 prius and got new 12v agm battery and show the display, showing 12v or not 12.6v and When i start the motor on, it wont show 14.4v, just 13.7v with new battery. How come? If so Maybe the short charge circuit ? Where that short charge circuit.
Hey love ur video I have a question see I was teaching my son to drive and didn't realize he was stepping on the gas and break pedals..ijust bought the car a few days ago now I'm having trouble with my car please help
Hi, I have a 2006 Toyota Prius that is not starting (getting in ready mode) but every thing else comes on. I check the battery using the diagnosis method and the volt is 12.3. the only time it starts is if I remove the two battery terminals and hold both connected to each other for few minutes and then put them back on the battery before it starts (get in ready mode). How can I fixed this problem? Please advise
hey! this car has the original battery, it's never shown any signs of failure. These second gen Prius packs are highly reliable and have extremely low failure rates.
I put in a deposit for $1000 at a dealership for a 2012 Toyota Prius. I am supposed to go pay the rest today September 15, 2022 or tomorrow. The car is being sold for $5500, the Carfax is clean but I’m just a little worried that it is over 220,000 miles. Can you advise me if that is a good buyer or not?
hey man! I'm glad to see you're looking for a prius. Let me give you some advice. The price is fair for a 2012 with high miles. As Long as you test drove the car and it's in good working order there is noting to be too worried about. The reality is for 5K you cannot even buy a cheap Honda Civic with 150K at this point. The prius will be way more economical and it's a much nicer car overall than any economy car you could get for under 7K. Also there are so many of them around that If you have battery issues a rebuilt pack is cheap (under 1K).
Whenever i attach computer to check my car after that my car doesn’t start and then i have to start with cables… when i check like this it shows 13.9v but on computer its says C2318 low voltage error(power supply fault) . Can you please guide me what should i fi? Should i replace my 12v battery?
I don't see how this tests your HV battery since there is a DC-DC converter which drops the 2xx volts from the HV battery down to 14V to charge the little 12V battery. There is soo much more voltage and capacity in the HV battery its condition will never effect the 12V charge circuit.
hey buddy! This test does not self test the HS battery, you're right. I am only attempting to show that you can self-test the voltage on the 12V battery and then when the HV battery powers up you can see it's powering the 12V battery. Ofcourse this is not a 100% indicator of the HS battery's health. But for the most part it's an easy on the go quick test to do if buying one of these cars.
@@hybrid32494 got it. From the video title it appears its about testing both batteries and like I said, the HV battery could be on its last leg and still provide a measly 14V for the 12V battery charge circuit. Def not any indication of the HV battery health except that it is there.
@@hybrid32494 and I found this which looks like the sure way to figure out the health of the HV battery. I changed out the battery on my 2001 Prius years ago and learned the process of loading the vehicle(go up hill) and full throttle while recording all battery module voltages for real battery health indications. th-cam.com/video/z7RFw8JAr9s/w-d-xo.html
@@douglarue8485 totally right! What really matters on these GEN 2 Prius cars Is the damn speedometer and entire dash not illuminating due to the Capacitor failure which powers it. Currently my prius is doing this. I'm having to disconnect the white terminal from the 12V battery to reset it constantly now, especially n cold weather.
@@hybrid32494 ugh that sucks... Looks like a PIA to fix as it requires a dash disassembly. Pretty easy fix once it's apart but ugh, I hate plastic dash parts. th-cam.com/video/NqJMywptHyA/w-d-xo.html
Hi, I was driving my 2008 Prius and the main battery display dropped from about six bars to one bar, then the petrol engine kicked in to try and charge the battery. Moments later the car basically shut down. Petrol motor was spluttering and electrics seemed to have died. On my display it says Problem!
No that do not mean the hybrid battery is good. The hybrid battery is charged from another unit om the engine call a dc inverter. The procedure in this video to check the hybrid battery is 100 percent false as it only details how to check the auxiliary 12 volt battery.
Hi I'm noticing that my battery goes off sometimes because my clock and radio is different. I checked the battery like you posted and the battery has good numbers
hello, is it possible you have a bad connection on your 12V battery itself. Maybe it's causing intermittent power loss? I've never heard of this problem like you're describing, unless the battery was somehow disconnected.
hey man!! thanks for watching. You gotta check the engine oil, all the coolants and make sure you do a thorough test drive. It's honestly not any diff than inspecting any used car. With the hybrid it will pretty much tell you right away if the battery is bad, but make sure the car can drive in electric mode only under light acceleration from a stop to about 20 MPH. Let me know,.
I tried this and although it worked, it gave a much different reading that measuring the 12v battery at the terminals itself (the one in the trunk). 11.9v vs 12.4v.
Hi i have a 2008 Prius, and i had some issue on my double screen and dashboard and the issue is the both of them is sometimes is working sometimes its not working, driving is really good but genereally the double screen is not working so you know why do them like that ? Do you know to what is the solution for this issue
Thanks for the video! Quick question, when the volt screen first shows up my 2011 hybrid Prius is at 11v resting but when I start the car it jumps to 13.9/14.4 does this need a new battery?
hey buddy! You got it! I would say your Starting Voltage is on the low side. Battery isn't dead, but if you live in a cold climate area it could easily die overnight (which is what happened to my in NYC a few years ago). If you're not really getting temps under 40 degrees, it should be fine for a while. IT will be fairly obvious when the car does not fire up, and you will know right away it your 12V battery.
Hi friend do you have info about my i i checked my hybrid battery status many times but my battery volt is stuck 14.1 even when i drive voltage is still same like volt isn't low or high just stuck everytime 14.1 .. what is this matter kindly guide me ..
My auxiliary battery is at 11.6v during test. Started the car, it went to 13.5v. I have an error code PA080. Obviously, the 12v battery needs to be replaced but is it what is causing the error code or does it also mean there is something wrong with the hybrid battery too?
hey man, it sounds like your hybrid battery is fine, since it jumped to 13.5V after that means the extra voltage came from the hybrid drive battery. How old is your 12V aux battery at this point. They generally last upto around 5-8 years. Mine is around 7 years at this point.
Yeah issues with the hybrid battery pull your disconnect out of your hybrid battery put it back in and restart your car and drive it and see what happens that should reset your hybrid battery

Hi I just changed my hybrid battery 2006 Toyota Prius but I don’t know why the car is run average 35 miles per gallon before my hybrid battery run 50 miles per gallon.I wonder if the mechanic cheat he didn’t change hybrid battery at all ?
hey buddy! There is some noticeable movement when the gas engine turns on, that is normal. Sometimes when the battery is low the generator kicks on a little violently also, I did notice that myself. What matters is the hybrid system works well and you're getting at least 45+ mpg, lol.
@@tylerspatz6337 I totally understand what you mean! I can tell you I've owned 2 of these same cars and each has never let me down and I average 50+ mpgs at all times. You really can't kill these cars, and the batteries very rarely fail. BTW I've got a couple other good prius vids on this channel.

If I'm driving and the Christmas tree red light comes up, will I be able to drive it back home if my 12V battery is good ? I hope you can answer me. And by the way...thanks for the video
I have problems with my 2006 prius instrument panel, whereas, sometimes it won't light up, the check eng. light, tire and brake comes up whenever the panel does comes on; I recently acquired the vehicle, and don't know hardly anything about it, can you please give me some suggestions
HEy buddy, any voltage under 11 is low for the 12V battery. Do you notice any of the dash lights going out or any electric issues upon startup? The 12V aux battery is responsible for the first few seconds of starting the car, after that the hybrid battery takes over, thats why you see a voltage jump to 13.6 V.
The prius doesn't actually start the engine with the auxiliary battery, unlike all other cars. The voltage of the auxiliary battery can easily be tested with a multimeter either in the fuse box (where the jumpstart point is) or in the tailgaite right area, where the battery is. Maybe, don't drive around while you're videoing showing stuff to us, it would be safer for other roaIf d users. My prius aux batttery was stuck at about 9.6 too - suggesting 1 or more of the 6 internal cells were not happy. Sometimes you can charge the battery (google videos on using a dumb charger to renew an old 12v battery) with a 'dumb' charger for a few hours to get the voltage back up, but in general, the battery's health is hurt by being unused/uncharged for a long time, which is probably how your car and mine got so low.
2008 Prius I The 12V was dead about 10 days ago, AAA started it and, as per their instructions, I left it c charge at home for 30 minutes. Next day I checked battery through internal diagnostic system and it fine. Between 1.28.2020 and 2.5.2020 I used car w/o problems. Last night it was dead again -hadn't driven it since the day before. I can call AAA again, but would like some advice or thoughts on next move after that/ Thanks
I dont think this is telling how the hybrid battery conditions are..... What you showing is the car battery getting charged by the alternator....if im wrong, explain how you know this the hybrid battery status. Thank you
hey buddy! This Self-Test is not intended to show you Hybrid battery voltage, I am merely demonstrating the 12V battery and the fact that as soon as the Traction(hybrid) battery turns on you can see a jump to 14 Volts on the 12V readout. This only means your hybrid battery is not dead. There is no onboard way to test the hybrid battery unless you are able go up on electric power alone on a small incline.
I just did this test on a car I bought yesterday (2008), battery is under 12v and the Hybrid battery is at 13.9, what would you recommend in this situation. thank you!
Hey buddy! I would say you most likely would need a new 12V battery soon. It really matters If you're in a state where it's pretty cold, the only time my 12V pack died was in wintertime when it was like 20 F outside. Otherwise it has never let me down. Even the close to 12V charge will start the car, but if it gets cold, then it's probably gonna be over with it for the battery..
hey man! Thanks so much for watching! Good luck with buying this car, it's one of the best used cars you can get. Check my channel for more prius videos.

None of what you wrote here is true, the prius is among the most reliable cars in the used vehicle segment. Sure some batteries fail, but when the miles have went far beyond the car’s life cycle.
Although this is a good way to see what the resting voltage of the 12 V battery is, and also shows if it is being charged, this has nothing to do with the Hybrid driving battery.
Exactly, this guy is a clown 🤡 .
Exactly. Our Yaris hybrid battery is 400V!
Ok good to know
This guy is a tool. At least he knows the alternator is good
Prius does not have an alternator. It takes traction battery’s high voltage and through an inverter/converter charges the 12V utility battery.

True, since the motor battery is a high voltage one(can't remember if 300v or more, or less on the 2nd one) and there's a buck converter or transformer somewhere.( i vote for buck with a coil).

Sorry, but this is not a good test of the hybrid battery because the prius 12v battery is very small (Amp hour capacity) and it only takes a few amps to push a fully charged 12v battery up to its full charge of 13.8 volts. The hybrid battery in the prius has to send 100s of amps to the motor when needed for traction
this is the secondary battery not the main hybrid battery back

yep, very useful tool when you have a prius. THis will tell you the hybrid battery voltage and the 12V AUX voltage too. and you will see it change as you drive to check if the charge output is good.
Thank you for all the info. Blessings
Rápido y claramente explicado y filmado. Muy buen video, gracias.
is there a way to test this on gen 3s?
This is the auxiliary battery not the High Volt one. The 14v when in Ready Mode indicates that your 12v battery is accepting a charge and that your inverter works.
Another way to get out of the diagnostic check mode without turning car off is press and hold display for 5 seconds and let go it will exit out of it 😃

FYI - The test you show only verifies the 12v Aux battery, and the vehicle's alternator. The diagnostic screen shown does not provide any feedback regarding the traction battery which should be in the region of 346v (comprising of 96 Lithium cells in series of 3.6v each).
hello my friend! Thank you for this great information, you're correct. This video is only intended to show the PRIUS SELF TEST diagnostic screen. It will show you the actual 12V battery levels in real time, and that is the purpose of this video. To test the hybrid (traction battery) there is no way to do that with any on-board equipment without other external equipment.
@firenzaman the Prius does not have an alternator
@@Madvizion Ah, thanks for clarification. How does the aux battery get charged?
@@Firenzaman it gets charged through the DC to DC inverter located under the hood of the vehicle.
Great video. When I start the test volts are 12.4 then when I start the car it drops to 11.2. Goes to 14.2 once if completely starts and is in ready mode. Is the drop to 11.2 a concern?
How can o check the battery is good or not good if I want to buy a used Prius. Thanks 🙏
Dr Prius.
My catalyc comverter got stolen on my 2009 prius.. I drove like that for less than 2 miles and got red triangle with exclamation point on it. When that happened car started to loose power and eventually died on me:( right now I have it at a muffler shop where they will put another catalyc converter on but car still does not turn on..when I press on power button all the lights come on with rd d triangle like if car it's on but engine not on. Lights, radio and power windows work . The windows are slow though so I don't know if battery it's dying. If I remember I have one purple bar. Also keep getting a message about something that car needs to be on flat surface and something about the transmission .
A while back it completely died on my while I was changing the passenger mirror, after I was done I gave it a jump and everything was good. This time it won't move from one purple bar even after a jumped it.
hey man! The Prius Cat Converters being stolen is a real problem now. I have friends who had this happen to their car too. Reality is, these cars are so good and last so long that parts are highly desirable. You don't see anybody cutting parts off a KIA, right?? lol. Anyway, it sounds like your Gas engine is not kicking in to charge the pack because you're missing part of the exhaust system. Once it's replaced it should go back to normal.
Yea it's crazy. This rides are hot right now. To replace the part here in california is close to $3000 cause it has to be straight from dealership cause of the Cali emissions laws:(
Here in Pakistan we get only used batteries for replacement. I had code p3000. So I got my hybrid battery replaced. When I used the method you described. The battery voltage are 12.1 but after turning on the car on diagnostic mode the voltage dropped to 11.8. Hybrid battery display screen also shows sudden drop of bars from blue to purple sometimes when I stop the car for few minutes. And on two purple bars car keeps running for many minutes but the third blue bar takes alot of time to appear. Its not happening always but randomly. Can you give your expert opinion whether the battery is good or bad.
It’s ok as long as it turns on
Need to replace 12v battery right now ur using to much power drain to feed it...lowering ur gas mileage. And slowly depleting ur hybrid battery
Thx you bro for sharing this beautiful video. But is it because of the healthy alternator that bring the voltage up to 14.4 volts? Thx
hey buddy! These cars do not have an actual alternator. What happens is after the initial few seconds when the 12V battery starts the car's electronics, the Hybrid Drive battery kicks in and takes over, that is where you're seeing the 14+ volts come from. Not the alternator really.
@@hybrid32494 Hi, how do I put my Toyota Camry Hybrid 2018 LE into diagnostic mode? Thanks 🙏
My only problem with using this method is that the central display sometimes doesn't work. It will go off for months at a time (no consumption readout, no radio, etc.) and then start working for weeks or months. Dealers and specialty shops won't try to repair (it's obvious it's a faulty connection, but I realize it could be a bad solder on a chip, which would be ridiculously time consuming to find) but will only replace it at quite a hefty price. Trying to keep this car running, since I'm now retired.
hi Diana! I know exactly the reason why you're having intermittent DASH light problems, this is a common issue in all older prius cars. It's called the combination meter malfunction and results from a faulty capacitor in the dash cluster. Very pricey to repair. There is only one easy and reliable (but temporary fix). In the trunk you will find the regal 12V battery (not the hybrid battery). You need to disconnect a white wire that clips into the battery for 10 seconds. This will reset the car's electronics once you reconnect it and the dash will light up. Often times this happens in the cold, but it's a 100% temporary fix.
There is a video on TH-cam I believe that details the MFD repair. Search for 2nd Gen Toyota Prius Fixing the Multifunction Display and Combo Meter There are other videos as well, though if you have the time and are willing to learn and do, is a cost effective option.
@@jafinch78 thank you
This video goes more into the MFD since sounds like the issue if not only the connection. Video titled DIY Prius Gen2 dash Instrument cluster and MFD repair 2004-2009. Problems I encountered shows some extra info.

Youre a legend. Great help man..
LOL I love being a legend!!! ahaha. Thanks for watching my dude.
@@hybrid32494 legend in my lunchtime
Is this accurate? These are the exact numbers you get from an alternator powering a 12v battery setup.
Hi
Thanks for your clip. My Prius 2007 red triangle is on now . How can I diagnose that please ? I just want to know is it because of 12v battery or hybrid battery?
Thanks.
I had that triangle of death after replacing the 12v battery myself. I just drove it as normal and after two drives it went off by itself.
My battery shows 90 to 100% in the morning, and when I start driving, no further than 2 blocks, the Battery drops to one bar. And then slowly builds back up. But lately, it started doing it right after I get off work. The battery gets down to one bar all the way home, for 42 miles. My gas mileage is bad 38mpg. I installed some cheap injectors, and my mpg went to 48mpg, but I got a check engine light. Then, after almost three months, I went back to the old injectors bc the car had some misfiring issues when the car was coming to a stop. I suspect a dripping injectors so with the old injectors, the misfire dissappear but the bad mpg came back.
From my understanding every car (non hybrid) increases voltage when the vehicle is started by means of the altinator starting the 12v battery.
In Toyota hybrids the 12V battery is charged by a DC-DC converter in the inverter assembly. That is why the battery voltage came up when the system went ready, and will eve before the engine starts. No alternator or starter on them.
Kindly demonstrate also how to self check the hybrid battery in toyota aqua hybrid
I’m about to buy a Prius 2007 is good video thank you what did you recommend to check more things
Quick query: “To check the hybrid battery, turn the car on…” i’m confused here because I thought the car was already on and nowhere in that particular section does it say to turn it off. So how do we get from testing the 12 V to testing the hybrid? Your car appears to show the display illuminated whilst the car is off which I’m confused by. Someone clarify for me please?
read the cooments he explains it dozens of times
great job, really good info
Glad it was helpful!
Thanks a lot for video. It was very useful. I have one trouble with Prius 2006. Abs module seems like bad, but the dash board is coming on and off. When abs is working dash board coming on. If you know something can explain what is the problem ?
hey buddy! these cars sometimes do have an issue where the dashboard does not illuminate. You can get it to light up by disconnecting the 12V Gel Auxiliary battery in the trunk for 10 seconds. It will reset the dash's capacitor that powers the dash on. Its a weird system, but older Priuses (including mine) does this sometimes.
Thank you for the video. I have a question. You have a hidden camera option. Why do I have the same? Why can't I connect a camera to the device?
hey buddy! What do you mean "hidden camera option"? Do you mean the backup camera in this car? This trim level has a back-up camera, some model cars do not (typically the lower trim levels on 2006 and under models).
Is there any miles like 150k or 120k when original battery fails need replacement?
Thanks
Love your car videos, very helpfull. Keep up the good work👍🥇😊😊😊
Should I be concerned if I don't have all the battery bars lit up? I have all but the top two bars lit.
Why is your brake light on? Maybe you can do a video when you change brake pads?
hey!, love your comments, motivates me to come up with more car video topics. So is your brake light on in your car? This prius actually still has it's original brake pads and rotors, even at 145,000 miles. Incredible, I know. Never worried about brakes. I can probably get another 40K on the current brake pads.
@@hybrid32494 My Prius had the brake pads and rotors changed at the 62 000 miles. The dealer recommended to change it every 38 000 miles. But it depends on how you drive. My car doesn't have the brake light ON but the pads make noise when i brake.
@@hybrid32494 Imressive that you have the same pads👍😁
I cant believe you went through your brakes so quick, do you not use much of the slow regenerative braking techniques? You should try to visually check the amount of brake pad material still on there, it's possible that the pads are actually ok, but the slide pins are rusty and they don't release the brake pads back to their normal position.
@@hybrid32494 Thanx for response. I actually got checked the brakes at dealer and they didn't find the problem. Keep up the good work bro👍😁
Thank you very much it's really helpful
Hey buddy! Thanks for watching! Hope this video helped you out!.
I have a question, I have 2005 prius and got new 12v agm battery and show the display, showing 12v or not 12.6v and When i start the motor on, it wont show 14.4v, just 13.7v with new battery. How come? If so Maybe the short charge circuit ? Where that short charge circuit.
So I noticed your TPMS light flashing... guess that is a common theme with the prius.
Hey love ur video I have a question see I was teaching my son to drive and didn't realize he was stepping on the gas and break pedals..ijust bought the car a few days ago now I'm having trouble with my car please help
Hi, I have a 2006 Toyota Prius that is not starting (getting in ready mode) but every thing else comes on. I check the battery using the diagnosis method and the volt is 12.3. the only time it starts is if I remove the two battery terminals and hold both connected to each other for few minutes and then put them back on the battery before it starts (get in ready mode). How can I fixed this problem? Please advise
Hi! Are you testing with the original battery or have you replaced that?
hey! this car has the original battery, it's never shown any signs of failure. These second gen Prius packs are highly reliable and have extremely low failure rates.
How can I get the big red triangle with ! In it to clear off?
I put in a deposit for $1000 at a dealership for a 2012 Toyota Prius. I am supposed to go pay the rest today September 15, 2022 or tomorrow. The car is being sold for $5500, the Carfax is clean but I’m just a little worried that it is over 220,000 miles. Can you advise me if that is a good buyer or not?
hey man! I'm glad to see you're looking for a prius. Let me give you some advice. The price is fair for a 2012 with high miles. As Long as you test drove the car and it's in good working order there is noting to be too worried about. The reality is for 5K you cannot even buy a cheap Honda Civic with 150K at this point. The prius will be way more economical and it's a much nicer car overall than any economy car you could get for under 7K. Also there are so many of them around that If you have battery issues a rebuilt pack is cheap (under 1K).
Whenever i attach computer to check my car after that my car doesn’t start and then i have to start with cables… when i check like this it shows 13.9v but on computer its says C2318 low voltage error(power supply fault) .
Can you please guide me what should i fi? Should i replace my 12v battery?
I don't see how this tests your HV battery since there is a DC-DC converter which drops the 2xx volts from the HV battery down to 14V to charge the little 12V battery. There is soo much more voltage and capacity in the HV battery its condition will never effect the 12V charge circuit.
hey buddy! This test does not self test the HS battery, you're right. I am only attempting to show that you can self-test the voltage on the 12V battery and then when the HV battery powers up you can see it's powering the 12V battery. Ofcourse this is not a 100% indicator of the HS battery's health. But for the most part it's an easy on the go quick test to do if buying one of these cars.
@@hybrid32494 got it. From the video title it appears its about testing both batteries and like I said, the HV battery could be on its last leg and still provide a measly 14V for the 12V battery charge circuit. Def not any indication of the HV battery health except that it is there.
@@hybrid32494 and I found this which looks like the sure way to figure out the health of the HV battery. I changed out the battery on my 2001 Prius years ago and learned the process of loading the vehicle(go up hill) and full throttle while recording all battery module voltages for real battery health indications. th-cam.com/video/z7RFw8JAr9s/w-d-xo.html
@@douglarue8485 totally right! What really matters on these GEN 2 Prius cars Is the damn speedometer and entire dash not illuminating due to the Capacitor failure which powers it. Currently my prius is doing this. I'm having to disconnect the white terminal from the 12V battery to reset it constantly now, especially n cold weather.
@@hybrid32494 ugh that sucks... Looks like a PIA to fix as it requires a dash disassembly. Pretty easy fix once it's apart but ugh, I hate plastic dash parts. th-cam.com/video/NqJMywptHyA/w-d-xo.html
Wow hyd you are the best thanks
Fantastic video 👏👏👏👏👏❤
Hi, I was driving my 2008 Prius and the main battery display dropped from about six bars to one bar, then the petrol engine kicked in to try and charge the battery. Moments later the car basically shut down. Petrol motor was spluttering and electrics seemed to have died. On my display it says Problem!
So s long as we are getting the 14 when we start the car the hybrid battery is good?
OK, im glad you figured it out! Yes anything over 13.8 is good. My buddy has a prius and his runs perfectly and only registers about 13.8 at most.
@@hybrid32494 then I wonder why out pruis had The problem with the dash board lights the triangle light came up and would not start
No that do not mean the hybrid battery is good. The hybrid battery is charged from another unit om the engine call a dc inverter. The procedure in this video to check the hybrid battery is 100 percent false as it only details how to check the auxiliary 12 volt battery.
Hi I'm noticing that my battery goes off sometimes because my clock and radio is different. I checked the battery like you posted and the battery has good numbers
hello, is it possible you have a bad connection on your 12V battery itself. Maybe it's causing intermittent power loss? I've never heard of this problem like you're describing, unless the battery was somehow disconnected.
I’m looking to buy a used 2006 Prius that has 144,000 miles on it. What are some things I should check and keep and eye out for?
hey man!! thanks for watching. You gotta check the engine oil, all the coolants and make sure you do a thorough test drive. It's honestly not any diff than inspecting any used car. With the hybrid it will pretty much tell you right away if the battery is bad, but make sure the car can drive in electric mode only under light acceleration from a stop to about 20 MPH. Let me know,.
@@hybrid32494 how far can you drive in electric mode for a good battery and how far for a soso battery and how far for a bad battery?
I tried this and although it worked, it gave a much different reading that measuring the 12v battery at the terminals itself (the one in the trunk). 11.9v vs 12.4v.
At what wattage will the hybrid battery be completely dead? And if it does completely die can I drive the car?
Hi i have a 2008 Prius, and i had some issue on my double screen and dashboard and the issue is the both of them is sometimes is working sometimes its not working, driving is really good but genereally the double screen is not working so you know why do them like that ? Do you know to what is the solution for this issue
Will this procedure work on a 2014 Prius?
Hi mate my 2009 Prius about a year ago started showing triangle warning light , I tried everything but still it’s there. Can you help me please?
Will this work for the Lexus CT200h since it's a Prius In a tuxedo?
Thanks for the video! Quick question, when the volt screen first shows up my 2011 hybrid Prius is at 11v resting but when I start the car it jumps to 13.9/14.4 does this need a new battery?
hey buddy! You got it! I would say your Starting Voltage is on the low side. Battery isn't dead, but if you live in a cold climate area it could easily die overnight (which is what happened to my in NYC a few years ago). If you're not really getting temps under 40 degrees, it should be fine for a while. IT will be fairly obvious when the car does not fire up, and you will know right away it your 12V battery.
Hi friend do you have info about my i i checked my hybrid battery status many times but my battery volt is stuck 14.1 even when i drive voltage is still same like volt isn't low or high just stuck everytime 14.1 .. what is this matter kindly guide me ..
That 12v battery is stuffed
I’d also get your ecu checked because the big red triangle should have popped up by now due to low voltage on the 12v
I got it 08 Prius I change the big battery and it still charging battery and what would it be
Not charging
do you mean the 12V aux battery is not charging?
Yes
I changed both batteries
And it is not charging both batteries
My auxiliary battery is at 11.6v during test. Started the car, it went to 13.5v. I have an error code PA080. Obviously, the 12v battery needs to be replaced but is it what is causing the error code or does it also mean there is something wrong with the hybrid battery too?
hey man, it sounds like your hybrid battery is fine, since it jumped to 13.5V after that means the extra voltage came from the hybrid drive battery. How old is your 12V aux battery at this point. They generally last upto around 5-8 years. Mine is around 7 years at this point.
Yeah issues with the hybrid battery pull your disconnect out of your hybrid battery put it back in and restart your car and drive it and see what happens that should reset your hybrid battery

hi sir, my car before start up 9.6 and after started engine it goes to 13.6 ! how do you think about my 12v battery and should i have a new one?
HEy buddy, any voltage under 11 is low for the 12V battery. Do you notice any of the dash lights going out or any electric issues upon startup? The 12V aux battery is responsible for the first few seconds of starting the car, after that the hybrid battery takes over, thats why you see a voltage jump to 13.6 V.
hybrid32494 how many v dose hybrid battery have?
The prius doesn't actually start the engine with the auxiliary battery, unlike all other cars. The voltage of the auxiliary battery can easily be tested with a multimeter either in the fuse box (where the jumpstart point is) or in the tailgaite right area, where the battery is. Maybe, don't drive around while you're videoing showing stuff to us, it would be safer for other roaIf d users. My prius aux batttery was stuck at about 9.6 too - suggesting 1 or more of the 6 internal cells were not happy. Sometimes you can charge the battery (google videos on using a dumb charger to renew an old 12v battery) with a 'dumb' charger for a few hours to get the voltage back up, but in general, the battery's health is hurt by being unused/uncharged for a long time, which is probably how your car and mine got so low.
@@hybrid32494 so is everything ok
That it jumps from 11.4 to 13.8 or 14.4?

You need to leave it in ready mode for at least 5 hours.
can you describe how to display dash lights that won't go on on my 2008 prius?
If you still need to know reply yes. I had the same problem.
I dont think this is telling how the hybrid battery conditions are.....
What you showing is the car battery getting charged by the alternator....if im wrong, explain how you know this the hybrid battery status. Thank you
hey buddy! This Self-Test is not intended to show you Hybrid battery voltage, I am merely demonstrating the 12V battery and the fact that as soon as the Traction(hybrid) battery turns on you can see a jump to 14 Volts on the 12V readout. This only means your hybrid battery is not dead. There is no onboard way to test the hybrid battery unless you are able go up on electric power alone on a small incline.
I put 14 in 15 size tires on... car slows down... what next...ty..
I just did this test on a car I bought yesterday (2008), battery is under 12v and the Hybrid battery is at 13.9, what would you recommend in this situation. thank you!
Hey buddy! I would say you most likely would need a new 12V battery soon. It really matters If you're in a state where it's pretty cold, the only time my 12V pack died was in wintertime when it was like 20 F outside. Otherwise it has never let me down. Even the close to 12V charge will start the car, but if it gets cold, then it's probably gonna be over with it for the battery..
