Prius (2004-09) :: Replaced Dead Cells On HV Battery - Code P0A80
Have replaced dead cells on wife's HV battery over a month ago. Threw this P0a80 code today and will barely move. She idles into dealership and they say it's the battery, really!
View 2 RepliesPrius C :: Dead 12v Battery - Check Engine Light On
So I went to start the car (2013 C3) and it wouldn't start. The batter was horribly dead (dim screen and would only go into POWER ON mode.) I charged the battery for like a half hour using a plug in charger using the hood terminals. When I tried to turn it on later, The only thing that came on was the check engine light (really dim) so it's not charged up enough yet obviously. The issue is now it won't turn off. That check engine light is still there. No other screens are on and the vehicle doesn't make any other noises (door ajar, etc.)

I went out in the 9 degree temp this morning to start my car and take off for work. I sat down and hit the power button and some console lights came on. The gear lights were blinking with a square light around each letter (P, D, R, B...) and the pips on the fuel gauge were blinking, beeping during each blink. Also, the green light on the power button was blinking and the little light showing that the key was not in the car was also on but the key was beside me. I turned it off to try it again.
Before I turned it back on, I inserted the key in the slot and hit the power button again and just the Check Engine light came on and everything else was black. There was a slow tempo click-click-click-click... sound coming from under the hood and the Check Engine light was just sitting there. I tried to turn the car off but the power button was not doing anything. All I could do is let the Check Engine light stay on and the click-click-click-click... sound chirp away. I went back out in a couple hours and the battery was dead.
Just seeing if that might mean something specific before I go drop about $200 on a new 12v battery later today.
Prius (2004-09) :: 2007 - Red Triangle Shows Up - Hybrid Battery Cells Overheats?
I have a 2007 Prius and the red triangle showed up. It has less than 50,000 miles. I noticed that almost right after I start it up the hybrid battery fan kicks on. This leads me to believe that maybe one or more cells in the hybrid battery are overheating due to charging problems. Is there a way I can check this out without going to the dealer?
View 3 RepliesPrius (Gen 3) :: Battery Dead / Jumped Then Display Freakout With Check Hybrid System
My 2010 Prius sat idle, parked for 7 days while my wife and I were on vacation. When we went to pick up the car, the airport valet said that the Prius wouldn't start, and so that they'd have to jump it. I approved the jumpstart, and got into the car. We got about 1/4 a mile before the display totally freaked out, including the "check hybrid system" as well as about every warning light there is. The car was beeping, acceleration was lost and it eventually died on the side of the road. The car would not start back up.
Had it towed to the nearest dealership. Initial diag from the service manager was that the 12v battery was dead. I approved replacement of that, and also authorized clearing out "a few software alerts". Got a call later in the day from the same manager (very nice guy) and there are about 11 errors that cannot be cleared out. Now he's asking for 3-4 hours labor to "trace the wiring" as suggested by Toyota. Apparently the tech had been in touch with them all day.
Prius (Gen 2) :: Replaced Hybrid Battery Now Only Check Engine Light On
I just switched out my hybrid battery and put in a brand new one. Now, the car isn't doing anything and all that's on is the check engine light. What now? I was told I had to tow it to Toyota and have them reset the computer. Sound right?
View 7 RepliesPrius (Gen 2) :: 2006 Cells Replaced, Red Exclamation Mark / Check Engine Light Appeared
I just bought a 2006 prius. It had 2 bad cells in the battery pack. I replaced the cells and all seems to be well, they all read the same voltage and the car appears to be driving, charging, working.
I still have the red exclamation mark and check engine light. The only code I get says to replace hybrid battery pack.
There are no other specific codes or issues and it runs perfect. Basically I guess what I am asking is how to clear the light or figure out why the light is still on!
Prius (2004-09) :: Check Engine Light Came On - Hybrid Battery Dying?
So this morning when i started up my car the cel came on. The car seems to be running fine so i decided id try to go to work and hope for the best. Well nothing happened and i made it to work fine, but i noticed i was always regenerating power. My drive is 45 miles all freeway and little traffic most the drive.. ive never had this happen on my drive to work and ive had the car for a year now. Could the hybrid battery be dying? i have a cheap scan tool but that doesnt mean i will get the correct reading...

View 15 RepliesSonata NF (2006-10) :: Dead Battery And Check Engine Light
2nd battery in 2010 Sonata 4-cyl died on my wife last night. Got a new battery today and put it in. (Couldn't move car even to push as there wasn't enough juice left to get transmission out of Park). Started right up after battery replacement and ran engine at idle for probably a half hour. Engine seemed to run a little funny. Lost RPM's and sounded like it might die a couple of times, but it stayed running. Now the dreaded check engine light is on. I've had a couple of stop-starts since it began, so I'm not sure it's going to go away. Car seems to be running fine now. Is there a connection between the battery going dead (so dead I lost radio presets and trip odometer readings) and something fouling up the check engine system?

Tested and replaced 2 bad battery cells in my 2007 Prius... Got everything put back together and now all dash lights are on and engine won't start... When i try to shift into drive or reverse it goes directly into park... I tested the battery without removing the safety key and the inside terminals are at 220 volts and the outside terminals are at 0 volts as shown by photo... Maybe due to a fuse somewhere?

View 4 RepliesPrius (2001-03) :: Hybrid Warning With Check Engine Light On
I have a problem with my 2002 prius. I was driving home from work when all of a sudden my Hybrid Warning light came on with the check engine light on. On the screen, it gives me a (PS, Battery, and ! ) and the "!" was the one lighting up. The engine was roughing up sounds like it was gonna stop itself so I pulled over to the side and it turned off by itself without me doing anything except to put it on park. Then, i took out my keys and tried restarting it and all i heard was the "Ready" beep but not the engine and it won't move when i step on the pedal. After waiting for 10 mins., i tried restarting it and it worked i drove away and got home safely with all the warning lights i mentioned earlier still on. (Note: i was driving w/ the A/C on because it was hot outside..around 90s, also it was not overheating nor it was any battery problem because all the electrical were working properly.)

I own a 2005 prius. It is stock and i recently had the check engine light pop up as well as "problem" when car was started and 2 lights with exclamation point, one on a car and ones in lil brackets. I believe it is called a "hybrid malfunction light". Well one day they all pop up and about 3 days later theyre gone. Only thing i did was fill up the tank, when they came on only 1 bar was left on the tank. My question is should i still take it in to see whats wrong with it? and what could of caused both lights to come on?
View 1 RepliesPrius (2004-09) :: Check Engine / Triangle And Hybrid Warning Light Came On
Possible hybrid battery failure in my 2004 Prius (96K miles).
Sunday before last, the check engine light, warning triangle, and hybrid warning light came on when I started my car at the grocery store.
Because I was close to home, I drove home and the car functioned completely normally. The next morning, when I started the car, the same warning lights appeared. However, when I tried starting my car with the headlights off (I always leave them on), no warning lights appeared.
I took my car to an independent mechanic. This is their written report:
"Found multiple check engine codes, P3000, sub code 123, V0100 sub code 211/330. These codes are set when high voltage control detects a malfunction in battery pack/ECU assembly. To check battery pack we took vehicle out on a test drive while monitoring the cells in the battery pack. Found that they are all weak and drop fast when battery is put under a load. Code C2318 is a low voltage error/power supply malfunction code with the auxiliary battery. The voltage spec for setting the code is 9.3 volts, this battery is less than 9.2 volts."
In conversation, the mechanic also told me there was significant voltage variation across the cells in the hybrid battery.
I then took my car to the dealer to try to confirm this analysis. They were unable to read any codes because the independent shop apparently cleared them. The dealer was unable/unwilling to do more than read the codes to diagnose the problem. (Indeed, they seemed surprised that the independent mechanic could monitor the cells in the pack.) All they did was to drive the car around some more to see if the check engine light would come on. It did not.
The car has been driven 80 miles since the warning lights last appeared and appears to be behaving normally. From your perspective, does the report from the independent mechanic make sense and is it believable? And is their test under load definitive of a hybrid battery problem? Could the results be affected by the low auxiliary battery? Also, if I do have a hybrid battery problem, what are the chances of being suddenly thrown into limp mode while driving it?
Prius (Gen 2) :: Charging Of Battery Cells By Running The Car Is Possible?
Is there anyway to charge a couple of batt cells by running the car.
Just replaced 2 packs and there voltage is 2-3 volts lower than the rest of the batt packs? the ones replaced are at 14.5 to 15 where the others are at 17-18 volts.
Prius (Gen 2) :: DC Charger To Test Battery Cells?
I found a decent deal on a 2nd gen prius. But I am going to need to repair the battery. I have already known that I can test and only repair the needed cells (since I looked into the situation when I was buying mine a year ago). Looking at the forums and saw there were a couple of chargers being recommended by the users; such as the supermate DC6 or the Hitec 44151 Quad X4.
I will likely want to charge 8 cells at time at least, as I would ideally like to get the car fixed in a couple of weeks.
Prius (2010-12) :: Check Engine Light P0A93 - Hybrid Overheat Alerts
Gen3 Prius. Once it turned 100k miles I took it in for an inverter coolant change per the maintenance schedule. The dealer charged $109 for this and the car had absolutely no issues prior. Got the coolant changed on 7/23 and then drove it short distances in town for two weeks with no issues. Once I drove it on weekend longer road trip got a check engine light P0A93 "inverter A cooling system performance". Shortly there after started getting hybrid overheat alerts and pulled over to let it cool.
I checked the inverter coolant reservoir and it was still above full. After letting things cool, I turned it back on and listened to the water pump. Seemed to be running fine, heard it clearly with my ear up to a long screw driver, touching the pump. Noticed that the hose leading to the pump was vibrating but the return hose out of the inverted was not. Also no turbulence in the reservoir. My guess is that they didn't bleed air out of the system.
