I need assitance on the following diagnostic report. My prius shows:-
1. Red triangle with exclamation mark,
2. On the LCD red car with exclamation mark,
3. ABS sign - on and off.
I am working on a 2003 Prius with 120k. It died when the owner was coming to a stop. He had it towed to the dealer who told him it needed an inverter and quoted $4600 to replace it. I replaced the inverter with a used unit from a wrecked car. After clearing the codes the car starts and runs but after a few minutes the triangle of death comes back and codes P3000 and P3009 are set.
Battery voltages are as follows.
Where the best place to start diagnosing the leak is ?
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.
So 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.
Could a bad transmission cause error code P3030 and P3009?
This car has no other symptoms other than the Mil light and the check engine light.
The first step is to clear the P3009 trouble code by unhooking the 12V battery for a moment or using a code reader. Now turn the key on/ but NOT start/ready mode, wait 30 seconds and if the code comes back, the leak is in the battery case. If the code does not return, turn key to start to "ready mode" and immediately shift to neutral and stay this mode for 30 seconds. If the code returns, the leak is in the power cables or inverter. If the code did not set, shift to drive and if the code appears now (can take up to a minute or so), the leak is in the transaxle. This is something that can be done in a few minutes without a scan tool or "megger" while never removing any components and not leaving the driver seat.
Ideally you want 3009 in battery case. That might be fixable without buying anything, just take apart battery and clean bus bars etc. If your bus bars are really "gooey", new ones are available from the dealer for a couple hundred bucks. Inverter is harder to replace, transaxle is the hardest.
I would like to understand what this reports mean.
View 3 RepliesMy 01 Prius is not charging the 12V battery and I have error code P3001. Everyone on here said P3001 is the HV battery ECU. (which I replaced with one from the Junk Yard and still get the error code)
I charged the 12V battery over night and Autozone says that its ok. They tested it with a little machine. The only other thing I can think of is that the Inverter DC-DC converter part is bad. How I can test that? (is there a way other than replace the inverter?)
I have a 2001 prius that I bought from a garage . To get to the point, it had a dead battery pack so I put a good used one in. It will start and run but I keep getting code p3001 which indicates a bad battery ecu. I replaced the battery ecu to the original one that was in the car ,but I still keep getting the code along with all the lights. I did some looking and was told to replace the HV. ecu which I also replaced ,but it did not solve anything. I unplugged a harness while it was running and than got code p3100 which indicates HV. ecu failure.. So I am not sure what is going on ,talked to toyota tech and he said it does not need to be reprogrammed ,but you have to buy a new one as the vin # in the ecu will not match up..

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 successfully replaced the HV battery on my own and it was so easy even this girl to do it! I drove the car about 300 miles when I got the triangle of death warning light again yesterday. I took my 2002 Prius to the dealer to read the codes but how to borrow a scanner (or whatever) from Autozone and do it myself.
View 19 RepliesNeed to diagnose a problem with my 2001 Prius. I was driving it on the highway when suddenly the hybrid system warning light and the main battery light, along with the check engine light came on. I pulled over, turned off the car, and turned it back on. The main battery light error cleared but the Hybrid System warning light stayed on as did the check engine light.
I took my car into the dealership and they told me that the 12V battery was probably low at some point but that they didn't find any problems.
The error codes that came up were: C1215, C1241, C1259, C1521, C1522, C1558, and C1559.
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 RepliesCar 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?
View 1 RepliesI 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.
I received my Mini VCI and sure enough the code was P3140 off of the hybrid ECU. My little bluetooth OBD2 scanner and torque just wasn't enough.
View 3 RepliesMy '02 Elantra would have a hard time starting up in the winter right after I filled the gas to full. Usually I would have to give it some gas to startup. After that, it didn't have problems starting up until I filled it again. This was only in the winter.
About a month and a half ago, it became really slow to accelerate. Since the O2 sensor light had been on constantly for a long time I never bothered to check it. Soon the car became really slow to accelerate and would lunge forward in spurts. The error codes I got were P0133 and the O2 sensor. I replaced the spark plugs and the spark plug wires, and this seemed to do the trick. The check engine light went away, the car sped up nice and quick. Also at that time, I put in some fuel injector cleaner.
The a couple weeks ago, P0133 and P0420 came back. It seems like the car is using up more gas than it should. There is a very minimal sluggish response when I push the gas. I have a spare ignition coil, but trying to find what it could be more specifically before I swap out more parts willy nilly.
How to diagnose the following codes: U0D00, P0711, P2300.
U0D00 - What this means.
P0711 - Transmission Fluid Temperature Sensor "A" Circuit Range/Performance. How would I go about fixing this?
P2300 - Ignition Coil "A" Primary Control Circuit Low
