Prius (2004-09) :: CEL And Triangle Of Death On 2007 Gen 2 - Replace Hybrid Battery Pack

I have a 2007 toyota prius. The car drives, but pulsates. The Check engine light and triangle of death are on. Diagnostic test says "replace hybrid battery pack", but wouldn't the car not even start if the bat pack were dead? What it could be? perhaps a bad cell or two? a bad ecu?

Prius (2004-09) :: P3024 Code After Reconditioning Battery Pack

Back in November/December I discharge/charge-cycled each module in my battery pack 3+ times after replacing 3 bad modules. I didn't get to reassemble everything and drive the car until the holidays. On short trips around town, everything seemed okay, but on longer trips (limited data here, but say 40-45 miles) I got the red triangle and some other lights (see photo). I read the code as P3024 which from what I find means Battery Block 14 Becomes Weak. I can clear the code and the car is happy until the next trip...

Prius (2004-09) :: Triangle Of Death Showing And Code For Bad 12v Battery

Had a company install fog lights on my replacement 2007 Prius I picked up after I totaled my 2008. When i went to pick the car up, the car wouldn't start. Showed the triangle of death and threw a code that the 12v was bad. Probably from having the car off and testing the fog lights continually - resulted in a drained battery. I picked up a brand new yellow top optima battery and thought this would resolve my issues. Nope, once the batter was replaced, the car wouldn't go into Drive or Reverse, only park or neutral. The current code is P0A0D. The shop is baffled. They removed all modified parts and still can't figure out the issue. They are currently replacing the interlock plug in hopes that this will resolve the issue.

Prius (2004-09) :: Code P3022 (bank 12 Low) And POA80 (Replace HV Battery)

Was crushing around and received the red triangle, check engine, DSC, etc. pulled two codes from my scan gauge P3022 (bank 12 low) and PoA80 (replace hv battery). Car was in limp mode, engine running full time, battery gauge showed hv battery depleting.

After reviewing other stories online, seems as though I might be looking at a new battery. Car is 2006 with 112,000 miles.

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!

Prius (2004-09) :: Battery Pack Won't Working

I posted earlier getting failure codes that might indicate something wrong with the battery pack. The codes were P3000, subcode 123, v0100 subcode 211/330. My independent mechanic said that I needed both the battery pack and the battery ECU replaced, based on these codes and the fact that they tested the hybrid pack under load.

At the same time, my auxiliary battery was low. You folks suggested replacing that first.

So I did. I have so far driven over 140 miles without the engine check light and triangle of death coming on again. But I do notice that the SOC screen shows my battery going into the green far more often and far more readily than I remember it doing so in the past. All it takes is a little downhill (say quarter to half a mile) and it will go into green--sometimes 100%.

I'm guess what I'm looking for is some sort of objective data that says my mechanics are right and not shining me on.

Prius (Gen 3) :: Yellow Triangle With No Code After New Battery

Working on a 2010 with 156k miles that threw a P0A80 on two separate occasions. Once before the 12v battery was changed, then the day after the 12v change. Decided to change the HV traction battery today with one from a wrecked 2014 with 56k miles.

After changing the HV batt I started getting the yellow triangle with no code associated with in. I would clear the code and drive the car a few minutes and then the triangle "check hybrid system" would appear.

Honda - Accord :: 2006 - CEL Code For Battery Pack Deterioration Came Up

My husband and I just bought a 2006 Accord Hybrid with 123,000 miles on it. The IMA and check engine lights came on two days later. I had the diagnostic check done on it and the code for battery pack deterioration came up. I read online where this code could be caused by the 12-volt battery going bad, and as it had the original battery in it, and the check on that showed it needed to be replaced, we did that. Two days later, the lights were on again. So we know we're going to have to replace the battery pack, which we're okay with, but what we want to know is whether the car will still run once that battery is completely shot. So far, it's still showing a good charge on it - whether that means anything, I don't know. Also, if it will run without the IMA component, will we be doing any damage to the car if we let it go for a few weeks?

Prius (Gen 1) :: HV Battery Dead - Code P3106 / Communication Malfunction

Against my better judgement I picked up the ex wifes 2001 Prius after the "mechanic" she took it to ran the HV battery dead. I picked up two Gen II batteries and built me a good battery. Then I cleaned all the corrosion off the harness and terminals and put the HV battery back in. The engine spins but dies. There are no engine codes but under the HV ECU cattegory I get a {P3106 communication malfunction, engine > HV}. I had a spare HV ECU and swapped it and get the same code. Spare engine ECU and the same code also. Not sure where to go from here. How to check voltages at the ECM ?

Prius (2004-09) :: Red Triangle With Code P0aa6 And Sub Code 612 Came On

have a 07 prius with 113k miles. It recently displayed the red triangle with code p0aa6 sub code 612.

I took apart the battery and nothing looked corroded, then on the inside of the bus bar i found a small amount of corrosion. After testing the cells i found 2 modules that were leaking voltage.

Since I had everything open I figured I might as well test to see if any cells were on there way out. The static voltages were pretty close around 7.8v, there were a couple modules that were .3v apart that I'm doing more testing on. I load tested each module with 1a, is 1 amp enough for a load test? I have a 100a load tester but figured that was way too much. They were all ok under load test, dropping about .6v and returning to original voltage within a few minutes.

Then I decided to check capacity on the bad cells, they were about 500mah, got to 1000mah after 1 discharge/charge cycle. I tested the capacity on a cell I thought was good and so far it discharged about 1050mah until it reached 6v, this was from 7.77v. I'm giving it some time to rest to see if it goes back up a bit and then I'll discharge some more till it stays at 6v. Even if I get a little bit more in it will be way under the 6500mah it should have or even the 3500mah that I've read is acceptable.

Since all of the modules have parameters that are pretty close I'm thinking the capacity will be pretty close as well.

Prius (2004-09) :: Still Red Triangle After Plugging Battery Right?

I recently cleaned all of the corrosion off the copper bus bars on my traction battery. When I got everything put back together I went to start the prius up and got the red triangle. I then remembered that I forgot to plug the master orange switch back in. After doing so I still had the red triangle so I turned the car on and off a couple times and it went away. Is this normal behavior from forgetting to put the master switch back in an attempting to turn the prius on?

Prius (2004-09) :: Red Triangle / CEL And Red Car At The Top Of MFD - Hybrid Battery Failing

i have a 2006 with almost 200k miles. Got the red triangle, check engine light, and the red car at the top of the MFD. I ran the codes and got P3000. Does this sound like traction battery failure? The car still turns on and ICE still cycles off and on.

Prius (2004-09) :: Red Triangle Of Death (P0A80) - HV Battery ECU?

I've pulled the HV battery from my 2007 Prius with 144, 000 miles given recent Red Triangle of Death (P0A80) and looking to replace battery pack but want to rule out the ECU. I've searched the threads and found mention of testing the ECU but wasn't clear.

How to test the HV Battery ECU in or out of the car? Using a volt meter and light bulb, etc......I would really like to rule out the ECU before putting dollars in a rebuilt battery pack.

Prius (2004-09) :: New Hybrid Battery - Red Triangle Pop Up Intermittently

I have a 2007 Prius with 107k miles. Last July it had a minor drivers side front end collision. Last November it had the hybrid battery replaced. I believe all this is unrelated just putting it out there for information.

I am currently having the red triangle pop up intermittently. When it does a "problem" message will display on the MFD. This seems to occur most often after a long downhill or when the Energy display is showing the hybrid battery is nearly full.

The hybrid battery seems to be functioning normal and the car is driving normal and has expected fuel economy. I do have a headlight that cuts out occasionally but no other noticeable electrical problems. I do not have a diagnostic device to get the codes.

Prius (2004-09) :: No Power / Low Battery On MFD / Red Triangle Light

I changed my oil, oil filter, air filter at 90k for a trip to Miami this past weekend. Uneventful on the way up. On the way back, stopped and did some shopping before hitting alligator alley to come back home. As I got on the alley after paying the new $3 toll my 05 prius with 90k miles on it would not go over 65 with my foot on the floor and the battery on the mfd was in the pink. So I drove to the nearest exit, checked the fluids etc, all good. Got back on same thing so I put on hazards and stayed on until i could get off on a much slower road. I was going about 55-60 and it would go no faster.

As I got to a place I pulled over DC'ed the negative battery cable and let it sit for a half hour. I then attempted to get going and it seemed to be running fine until I attempted to pass a car and the car seemed to lock up and lose all power, check engine light came on and the red triangle light came on. I pulled over and let it sit again. I then got it to a gas station with the check engine light on. I put a few gallons gas on and tried to limp it home. It made it home and the battery seemed to recharge back to all the blue it can get to, but has yet to hit the green.

Prius (2004-09) :: 2004 - Red Triangle Came On After Changing 12V Battery

I have a 2004 Prius, the Red triangle came on intermittently and went off so I changed the 12V battery last night, after changing it the red warning light went off and everything seemed okay. Today while driving, the warning light came back on. I checked the battery voltage via diagnostic mode on the cars computer and the specs are what they should be. I noticed the following error codes in the computer:

01-D5, Sub-code: 190-30-8
01-DC, Sub-code: 190-B7-8
01-DC, Sub-code: 1C6-4D-F

Not sure if these are what is causing the problem.

Prius (2004-09) :: 2006 - Triangle Of Death Came On, Battery Died

Got the triangle of death after letting the car set during my 2 week vacation. P0A80 and Battery block is 14.17V all the rest above 15.35. That's a lot of money to repair a car. Not sure if I want to cut my losses and move on or replace it and drive as long as I can.

Prius (2004-09) :: Red Triangle Light Came On When Started The Car In The Morning - HV Battery?

I bought a 2005 prii with 145k miles about a month ago and have since driven it 1,200 miles. A few days ago, the red triangle light came on when I started the car in the morning. I had to get to work so I unplugged the negative on the 12v and reconnected it. It started and it drove just fine. I get off work and the same thing happens. I did the same thing and drove home just fine. I then ordered a optima yellow top from elearnaid and it was shipped and arrived in 1 day!!!

I installed the battery this morning and called the dealer to notify them of my situation. The light didn't come on so I thought it may just be the 12v. But of course I didn't wanna run out of warranty and then the hv battery completely goes bad. The dealer tells me to bring it in and I did. They "diagnosed" the car and could not "repeat" what had happened to me. They said because I unplugged the 12v, it erased any codes. I thought it's always saved on the ECU? anyways, I told them about installing a new 12v battery and they said, "that must be it." I'm at 147k miles right now and I don't want my 150k / 10 year warranty to expire before something really goes wrong with the hv battery.

Am I just screwed and hope for the best for miles to come? Or is there a Toyota number I can call to tell them of the situation? I'm almost hopeful that it was only because of the 12v but at the same time, I have doubts.
