Prius (Gen 1) :: 2001 Car Stalled And Ran On Battery Only - P3000/123 And P3125/287
Jun 27, 2012
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 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 have been posting about P3125 fault which is inhibiting ICE from starting. During this time I have been charging and also testing the traction battery so that I could continue to investigate the P3125 problem.

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 bought an 01 Prius with 148k miles. It had code P3125 which mean bad inverter. I replaced the inverter with one from a junk yard with 81k miles. As soon as I was done the car started right up, and I didnt get electrocuted!
Right after the car started I got codes P3115 P3001 and P 3191. I cleared them out and turned off the car for a min.
When I started the car again I got codes P3030 and P3001.
This car has an extensive service history, It has a new Cat and exhaust, a new accessory and HV traction battery that are less than 8 months old. Crank position sensor is new. fuel tank is new.
What could be causing the P3030 and the P3001?

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 bought my Prius after I tested the car around town and on the highway and went smoothly. I drove the car about 200 km after the warning came on board, high temperature and cold engine warning (red and blue). Stopped the car and I found nothing to be hot (engine or inverter).
I rebooted and the errors disappeared but reappeared and on the highway (120 km) car no longer accelerate, pedal did not respond.Stopped and restarted repeatedly trying to get as close to home and a Toyota service. High and low temperature have appeared and disappeared after stopped and restarted. Warnings appear together, none or only one of them.
But after 600 km appeared turtle on board and the car stopped. I was unable to start. They came from Toyota and were able to start with another auxiliary battery and ran 10 km with a tester on the dashboard (at full throttle and the car accelerated 1 km / sec until it reached 60 km / h then accelerated normal to 125km/h. When he put the foot on brake and after that tried to accelerate again the pedal was non responsive and the car stopped again and they towed it.
Next day they told me that the ECU is faulty (the one located behind the glove compartment) together with the Auxiliary Battery.(1100 Euro ECU).They told me that the temperature sensor is 200 degrees Celsius with a cold engine.
We towed the car to another service closer to home (1300 km) and asked a second opinion telling me that is defective inverter. I decided to buy an ECU. (220 Euro/ second hand)
Meanwhile my traction battery died after they tried to start the car many times.
After I charged the traction battery (one module at a time), whole battery shown after charging 301 V.
Now I have the following :
P3120 HV transaxle / Wire harness
INF. Code 249 (Open or +B short in motor temperature sensor)

My Wife was driving our 2001 Prius and got the big triangle and the car went into limp mode.
The Codes were P3100 (info code 196) and P3125 (info code 325)
P3100/196 = Internal Error - Generator CPU Malfunction
3125/325 - Inverter Internal Short. - Generator Inverter Fin - Inverter Internal short
Clear the codes and the car runs fine, but the problem will eventually resurface.
The dealer wanted tor replace both the converter/inverter and HV ECU.
I purchased replacement converter/inverter from Ebay and inverter coolant pump (new) and installed.
Problem eventually resurfaced. I purchased replacement HV ECU from ebay and installed.
Engine would not start (does not attempt to even turn over), but was not throwing any codes. I had this same symptom with a third HV ECU as well. The part numbers on the HV ECU were exact matches.

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.

Working on a 2002 prius with 153k miles. bought it with a "Bad transmission" diagnosed by toyota dealer. Got I home and did a quick check but there were no codes. I drove it about 50 feet into my garage where it would shudder badly while being driven which from my experience sounds like a bad MG2 motor. Drained the oil and thought hhmmm th oil does not smell bad and neither did it look burned. Proceeded to pull the mg2 but found it looked brand new, no burned spots or any such thing. SO I put it back together and think its a bad invertor. put on a different invertor that I have lying in my garage that I "think" is good and start the car. get code p3125 and p3120 and still have the bad shuddering when i try to drive it..Is there any way to test it further before I pull the trans and put a new trans back in?

My 2002 Prius died the other day. Getting DTC P3125 when I ran it through my scanner, but I don't have an advanced enough one to get the sub-codes. It's got 215,000 Miles on it, so I would expect something major to be happening at this point.
Here's a detailed description of what happened --- I was driving down the freeway the other day and started noticing my car was sputtering a little bit and losing a slight amount of power. I pulled over to a restaurant to say hi to a friend; when I came back out I started the car and the check engine and battery lights came on. About 10 more miles down the freeway the car started heavily limping and barely was able to get me off the freeway, then the car completely died. When I would start it back up it would die in about 5 to 10 seconds. The 12v auxiliary battery, not the main hybrid battery, had completely died.
I figured it might have been just a dead old battery that needed replacement so I put in another new one. It ran amazingly for about five minutes around the parking lot, then the same thing happened again. It completely died just like before.
The 12v battery isn't getting re-supplied with the juice it needs. Something's wrong in there.
The either the inverter is shot, it's just overheating due to a faulty coolant pump, or the MG2 generator isn't putting juice back into the 12v system.
I checked the fluid reservoir. It looks like it's flowing, but there is a few bubbles floating to the top of the fluid. Is that normal?

Pulling into parking lot and the triangle and exclamation light appear on dash. Drive about an additional hundred feet with what felt like lower power and no noises.
- Check 12V after about an hour and it reads 12.4 volts.
- Read codes and get P3125 sub code 325.
- Temperatures and HV battery numbers all looked good.
- Clear codes and immediately code comes back with no start, nothing. Did this many times.
This code and sub code lead to the inverter failing. Being that there was no noise as a MG2 stator failure this also leads to an inverter failure right as the MG1 motor starts the engine? Inverter pump still running good as it was recently replaced along with ATX fluid. Within the last two weeks two HV modules have been replaced.

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 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.

My 2010 Prius with 205,000 miles, has hybrid system warning, and the dealer has reported that the hybrid battery needs to be replaced, there is a prob with one module but they do not repair the batteries only total battery replacement. Also needs front brakes and tune up. I did not expect the hybrid battery failure on this 2010 Prius since my 2008 Prius (184,000miles) had no issues thus far with the battery. Both cars are every day drive cars. Both cars have been really dependable and only routine maintenance.
I had no issues with the hybrid battery until after my last service when their was some factory recall having to do with the cars computer system, and routine oil change. The car stalled out the next day, but then restarted, this was odd it felt like the car was running but would not go into gear nor respond to the gas pedal, I'm calling it a stall, I'm not sure if this is correct terminology. So, it did this a couple of times the day after service, I was shocked but I just killed the car and restarted no other issues for about 3 weeks. Then I got the hybrid system warning on the computer screen on the dashboard, UGH.
I never expected my newer 2010 Prius to have a hybrid battery failure before my 2008 older Prius.
I'm looking for options with Prius over 200,000 miles. Both have been maintained through dealer services. Dealer reports the 2010 Prius with this issue is worth 1000.00 . I'm at a loss I really want to keep the car, but now I'm unsure, and obviously think it's worth more than 1000.00.

I picked up a 2003 that had a bad AUX battery and P3130 code. Just FYI, aside from the battery it drives fine. Kicks the Warning light after about 15 miles but since the battery was bad it kept getting reset. Replaced the battery with a nice optima conversion.
Took out the inverter coolant pump, tested the circuit (good), tested the pump (bad). Replaced with a new one from dealer. Set up the bleeder tubes and massaged the lines till the new pump stopped SCREAMING at me. Added probably 2 qts of TLLC total. Bleeder tubes never had enough pressure to push fluid back up to reservoir but got solid 2 inches of fluid with no bubbles. Topped of the coolant. Went for a drive around the block, made it halfway (about 28mph) before the light kicked in and the motor seemed to bog down. Limped back home and read the 3125 Code. Code reader does not give me sub codes.

I have a 2001 prius jap import. On a trip it beeped and up came the triangle, check engine light and car with !. The car lost all power and the engine stalled when I pulled over. I plugged in my obd2 scanner and no codes except 3000. Took it to our local toyota dealer who confirmed that code. Had the battery swapped out and still it does the same except now no codes. The car has below normal pickup speed and I can hear the engine rev a little but it does not seem to make any difference. Seems all the power comes from the battery. It will stall when all the error lights come on.

2002... 184,000+ miles
I was driving the car and triangle popped up and engine would not shut off while parked (key on) I hooked up the non prius aware scanner (carry one with me at all times) and don't remember the code, but it was a "HV malfunction".
I didn't shut the car off to clear the code as I was not home and attempted to drive it home, meanwhile engine never shut off. I had to come to a complete stop at a red light and the car died. tried restarting it but nothing. so I pushed it off to the side of the road and cleared the code. Tried again and nothing. didn't start, nothing. it beeped and error code popped up. Checked the code and it was p3125.
I know there are subcodes but online it was leading to inverter. but I replaced the inverter last year with a re involt. I had the car towed to my job for $50, to have it towed home, would cost roughly $168. When I got it to work, I did the screen thing and checked the 12v battery and it was reading 10.9 I have been meaning to get a new one for about a year now so I did.
I purchased a new optima battery and installed it yesterday, cleared the codes, tried to start it and nothing. error code p3125. What leads me to believe that it may be a transaxle, well actually a Mg2 is when my inverter went bad, it would start then shudder and die then the triangle would pop up. this time around, it doesn't even start. I have an appointment with the dealership to get the code with subcode read on Tuesday 10/15 for $98.7.

My 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.
