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...
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?
View 1 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?
View 19 RepliesI 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?
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?
2001 Prius
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.
I bought an 03 with 58K miles on it. shortly after I bought it the check main battery light came on, 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 diagnostic's 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 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.
I own a 2005 prius that I purchased used this year. This morning I had my first issue. I turned on the car and it gave me the following error message:
"Transmission p lock mechanism is abnormal. Park your car in a flat place and apply parking brake completely."
The parking break wasn't on and I was already parked in a basically flat parking space. I couldn't move my car because it wouldn't go into drive or reverse or neutral. (The car turned on, but the engine wouldn't start). I tried turning the car off, but the car also wouldn't turn off. I let the car sit for 5 minutes then tried again and the car turned off. When it turned back on, everything was fine.
My questions is: Do I need to bring this into a mechanic? The car seems to work fine now, but I don't want to be stranded again or do damage to the car by driving it with an issue.

Weird problems with my 2006 prius. Car has 54,000 miles.
4 times now over the last year, during abnormal braking conditions (someone swerves over at me on highway and I have to break and swerve suddenly to avoid), I get multiple warning lights, and the warning buzzer. Yesterday this happened, and I got the red triangle, the red brake light, the abs light, and two new lights on the LCD display I've never seen before. I pulled over and began to slow down. The brakes felt stiff, and the vehicle started to loose acceleration power. LCD started resetting itself. I stopped the car, turned it off, and turned it back on to find everything normal. I then drove 200+ miles to my destination without incident.
This is the worst case of this problem yet. My 12v battery was replaced last year after the first of these issues, with similar symptoms, but no loss of acceleration. The tech said the only code in the system was a voltage spike, and thus thought it needed a new battery. In every other case of the problem, I turn the car off and turn it back on, and it's fine. I'm about to drive 2000 miles next week, and want to avoid further issues...
My 2005 Prius has about 140,000 miles. I had been getting the intermittent warning message, "Caution: The transmission lock mechanism is abnormal" although the vehicle has been able to start and drive just fine. I replaced the 12v battery, which was suggested in several other threads. However, the warning keeps reappearing. Possibly related, my gear shift knob is "sticky". I'm able to get it into each gear (and the transmission remains in the gear selected), but the knob does not move smoothly like it used to.
View 2 RepliesSo I received the P1121 and took it to the dealer. They told me I also had a P3000. I called another dealer and they said the P3000 could be caused by the P1121 not giving it enough coolant. So I brought it back to the house, bought the valve listed in the forums, and I spent all day changing that + the coolant. I drained the coolant and between the reservoir and the radiator cap itself I refilled about 4 QT, and I saw that my inverter coolant was just below the low line, so I filled it up to the full line. Afterwards, I tried to get the coolant to flow, and it seems like I won't flow. The check engine light immediately came back on and the car said, "Problem." So I immediately shut it off and let it set for a few days. How do I get it so that the coolant starts flowing again. I haven't seen any of the levels move whatsoever on the radiator.
View 8 RepliesYesterday I got the "red triangle" and check engine light along with these 3 codes:
P0A80 - replace hybrid battery pack
P3019 - battery block 9 becomes weak
P3000 - battery control system
In April of this year I have the entire battery replaced, in September I got the triangle again and one cell was replaced under warranty. My warranty is good through April 2016, however I'm afraid that this new code P3000 is going to be something not included in my warranty.
What could potentially be wrong? This is a 2006 Prius with approximately 208,000 miles. I'm not sure this is worth it anymore especially if I have to keep putting in more money.
I've got a 2006 Prius that was a model car--no problems at all--until it turned 4 years and 1 week old in April 2010. Then my aux battery died on 22 April, with just 31,583 miles on the car, and was replaced at Downtown Toyota in Oakland, CA. My dashboard lighted up after hours, and since my regular mechanic (Art's Automotive) was already closed for the evening, I had it towed to downtown Toyota. No huge deal, except for the cost of the battery/labor. The codes were: C2318, b1421, b1200, b1207, and b1271.
4 weeks later, on 22 May, I pulled into my driveway, and 4 lights came on: the MIL, the VSC, the yellow ! inside the circle, and the Hybrid System Failure icon on the MFD.
I have a 2006 with 188,000 miles. We replaced the hv battery at 155000 miles. the car has been getting lower mileage than usual, around 36 mpg, we usually get 43 to 45 on the trip to work and back. the red triangle appeared and all the other lights a couple days ago. Borrowed a code reader, not a scan gauge, and the code came up P0a85, and says the HV battery is overheating. I checked the 12v battery and it is low, at 11.7 volts. So I am replacing the 12v battery, should be here in a couple days, already replaced it once, about 4 or 5 years ago.
View 15 RepliesI'm getting the 14 blink code on my Hymotion LED indicating that my 12v battery is needing replacement. My question is that the car seems to run fine with the exception of my mileage is low. I'm ordering the Optima replacement. Can I still drive around for another week without worry?
View 2 RepliesI had a 12v battery issue that I see common. 12V battery does not crank car. Jump car and works fine for a few days. I had this issue and it went away. Dealer said replace 12v battery, or just carry my charger pack with and use that unless it gets worse.
Jump ahead 2 months. I drive 50 miles each way to work 5 days a week. No issues. Yesterday, after my car sitting all day, I am backing out of driveway and get the red triangle. Code was P0A80. I looked it up. I cleared the code and was going to dealer if it came back. Today, after driving 50 miles into work, no issues, I get the red triangle. Code P3021. Fan started running back there too
My question : Would replacing the 12v battery useful for this issue?
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...
View 19 RepliesHad 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.
