I have a 2003 Prius with a hard falt code of P3000 main battery bad! But there is not anything wrong with the batt or how it runs. I cleared the code and in 10 miles or so it comes right back? I was thinking of a reflash on the computer, what to do?

I was able to pull codes this evening ( no subcodes).
The codes are as follows:
P3000, Battery Control System Malfunction
P3030, Battery Voltage Detective Line Snapped
Will the P3030 cause a P3000 to pop up since it appears I have one of the 19 voltage detect lines corroded or broken?
Once I fix this issue, is there a chance that the P3000 will disappear?
I was just getting the triangle and the Main Battery error on the MFD up until yesterday. Yesterday, the ! with the car came on (Hybrid system) on the MFD. I did not check any codes until today. Car will currently not start at all.
Aux battery voltage is confirmed to be 12.3 volts via the MFD in the diagnostic mode so it's good to go.
No one around has a scan tool that will also pull the subcodes.
I have a 2001 Prius with about 110K which I have owned since new. It displayed the hybrid warning light (as well as check engine) 2 weeks ago and I took the car in to the local dealer.. After a little muddling around they came up with codes indicating that the computer for the battery was going. I purchased that Part Number: 8989047030 Part Description: electrical, battery, computer H.V. SUPPLY. and the dealer installed that part a couple of days ago.
Now the following codes (and only these codes according to the dealer) are displaying and indicating faults in the main battery: P3006 and P3000.
A warning came on the display with the words "PS Main" and a picture of a battery. I took it to a dealer and he gave me the bad news: I allegedly need a new hybrid (main) battery. The diagnostic code was P3009--I didn't know about sub-codes, so I didn't ask if there were any. P3009 means that there is an electrical leak from the main battery.
View 9 Replies I have a 2004 prius with p3000 sub 123 this is the only code. This happen after a replace a cell. Now I check every cell all of them are around 8 V.
P3000 subcode 123 is abnormal signal from the battery...
Car stalled and ran on battery only. Set code P3125, and depleted aux battery. So, I replaced the inverter and recharged aux battery.
Drove it 20-30 miles test driving it, when the MIL came on.
Drove home and found 2 codes set, 1st was set while driving, 2nd was set after parking.
P3000/123 - MPH=22 MG2.RPM=1280 SOC=65% Position=D
P3125/287 - MPH=1 SOC=60% Position=P
Any TSB on this issue?
I bought an 03 with 58K miles on it. shortly after I bought it the check main battery light came on, after the local Toyota dealer told me I needed a new main battery. I had a P3000 code, a high voltage leak. It turned out to be corroded buss bars and cables, with 2 leaking cells, $1,450.00 latter the onboard computer said the problem was fixed and my display read normally for about 1,500 miles before I started getting that code and the check main battery light again.
I took it back to the shop tat did the work and they ran the diagnostics on it again, checking the main power cables that led from the main battery under the car to the Toyota Hybrid system, inverter? Under the hood they checked all of the high voltage connections, they all checked out fine. The shop then took several days to do an online search for possible causes. This led to the CV trans axle with its electric motors and generators as the possible culprit. The car is running and driving fine, so I did the 60,000 mile transmission oil change, suggested by my mechanic ( apparently the fluid becomes conductive with age) the check battery light will go off if I remove the secondary battery terminal for a minute or so and stayed off for 2 tanks of gas after the fluid change but it did come back on.
I can reset the computer easily enough and it will stay off for 3 to 400 miles but I'm looking to get the damn light to stay off. I'm going to change the trans fluid again. Changing the drive motor or generator?, can this be done in the car? or at all? It may be that if this is the problem it may end up making sense to just put in a new CV transaxle.
Like the title says, I was driving into work today and it came on three times. It went off for a little each time and then came back on.
View 13 RepliesI need to replace the main battery on my 2003 prius - whether or not they've replaced the battery, and what the end result was afterwards - did the car continue to last? Is this just a "regular maintenance' thing and all else will work swell, or is the beginning of the end?
View 12 RepliesMy main battery is dieing will my prius run on just gas until I can get it fixed? It is a 2001 hybrid. I need to get to work for the weekend.
View 6 RepliesOk just bought this 2001 Prius One Owner new car trade in it sat for a month without moving It needed a boost to start it then the three lights on the display lighted up PS+Main Batt + a pic of the car with a ! in it ! is it just from sitting so long and the Battery is low ? If I use an OBD and reset it will this and a charge take care of the problem ??
View 3 RepliesGot a recall letter last January from Toyota concerning a false warning light on my model. Letter mentioned that moisture in the cables was triggering a false warning message about the main battery. My 2002 was having this problem. The dealer refused to do the work. Told me they did that recall work in 2006 but I did not have the problem back then and Servco Hawaii told me that Toyota had not put that out as a recall back then. The light has gone off and on now for a year. Car drives perfect otherwise and only have 60,000 miles on it. What do I do?
View 8 RepliesI bought my 2002 prius with 120000 miles. Last night it died with the main battery light and triangle of death on. I haven't taken it to a dealer to have the codes checked out you, but will do it soon. My daughter was driving it when it happened and said the car started shuttering and died. She was able to drive it a few feet at a time before it would die again. Does this sound like a HV battery problem? I will be digging into it tonight.
View 19 RepliesI have a 2001 Prius, and a hybrid fault came up on the screen. I took it in and was told that #4 cell had a fault and it needed a need battery. I don't want to speed $3650.00 for a new battery!!
View 3 RepliesMy 2006 Toyota Prius with 130k miles i had the 12v battery replaced 4 months ago because I had the dashboard not turning on when starting the car. I drive about 200 miles everyday for work (deliveries) so the car basically is turned on all day.
Last week when I got home turned off my prius when I turned it back on later that night the dashboard would not turn on. Tried disconnecting the 12v battery and still no dashboard. Drove around like that for two days until Friday when suddenly the dashboard turned on and everything was fine.
Later that night I turned on the prius and the dashboard didn't turn on again, shut it off and turned it back on, dashboard turned on.
Now the big issue: The ICE does not want to turn on. Vsc and abs lights with the triangle of death are on. Code reader wasn't showing any codes.
I towed the prius to my mechanic so I wouldn't get stranded with only the electric motor running, he checked the 12v battery, fuses and relays. Moving the car around on his lot they discharged the hybrid battery. At first there were still no check engine light and no codes. Now the prius is throwing the p3000 code.
My wife was driving the Prius today and triggered P3000 code, the triangle popped up and the battery blower fan runs full on. I of course googled it and see it can be due to battery overheating? How should i go about trouble shooting this?

I was driving my 2005 Toyota Prius and all of a sudden some lights came on the dash. The orange check engine light, The big red Triangle with an exclamation mark on it, the orange VSC symbol, and the orange exclamation mark all at once. I also heard the fans in the back seat kicked in which I never heard before. It felt as though the car didn't have much acceleration. I took it to the dealer and they had it a whole week trying to figure out what it was wrong. They said they got the P3000 INF 123 code from the car which they said the HV control ECM for $2000. Needless to say I don't want to pay that! I found used ECM on ebay for $85 and I bought a scangauge 2 . I pulled 2 different codes out with the scan gauge 2 P0A80 and P3021.
Do you think the dealer diagnosis is right? What does the codes I read out mean?
I have a 2001 Toyota Prius. The inverter cooling pump was dead and I had the P3130 fault code. I replaced the pump and the refilled the fluid. After more than 4 or 5 times bleeding the system, now the pump sounds funny. It sounds like a water fall and look like it has too much air!!!! I can’t see any turbulence in the reservoir tank either.
There are 2 bleeding valves on the front side of the Inverter. Which one should be used to for bleeding the system? Both?
Does the system have any thermostat that could cause problem? Does it use the same radiator as the main one? What could cause having NO turbulence? I think the new pump will be dead too if it can’t make the turbulence.
Bought a used 2002 Prius in December of last year. When I got it home the hybrid system warning light and the check engine light came on, but after reading through priuschat for a few hours I thought to take a look at the engine air filter, which turned out to be utterly filthy. Replaced it and the car ran fantastically for the next 8 months, which was plenty of time for me to fall utterly in love with how quiet it is and how smooth a ride it is.
The carfax report for the car showed that its battery was replaced shortly before I bought it and that its transmission fluid was changed approximately 20k miles before that, so I thought (apparently mistakenly) that I didn't have to worry too much about either.
During these 8 months the car saw my regular mechanic for oil changes twice, had a bad CV axle replaced and I was told the serpentine belt was glazing and may need to be replaced with the next oil change, but neither I nor my regular mechanic noticed any other issues.
I would like to understand what this reports mean.
