    Ok, so first of all, thanks priuschat members for all the wonderful information on here. Its helped me so much already. And after tirelessly searching for answers to my problem, ive yet to come across anything exactly like my issues, thus my new thread ensues.


    I have a 2008 touring, i bought used only a month ago with 160k on it, but otherwise taken care of(cosmetically, atleast). After being screwed by the dealer and stuck in a contract, i finally had a chance to see firsthand they did absolutely jacksh*t to this car before selling it. It was almost bone dry on oil, so changed that along with oil filter of course. Ive had to replace all wiper blades, headlights, key fob, all air filters, all spark plugs, 12v battery, and it needs new brakes but haven't had the money for that yet, along with everything else. Including down payment, trade in car, and self-payed-for maintenance after the purchase, ive already spent 3400 on this car. Grrr. Anyways, about 1 week after buying car the master warning light, brake warning light, vsc light, and hybrid system warning light all came on while driving. Pulled over, turned off car. Turned back on, brake and vsc lights went out, but master and hybrid stayed on. Took to dealer, mechanic cleared codes and said it was fixed, and wouldnt let me see codes. I knew it was a crock of **it right than, but let it go. 2 weeks later, same situation, same lights recurred. Upon looking through the threads here i thought it might be 12v battery, put a brand new one in. 4 days later, same lights all over. Took to a different mechanic today, he pulled the following codes and cleared them, to see which would come back first. Not 2 hrs later, same lights all came back on but havnt had a chance to see him again to pull codes yet. Will do tomorrow, hopefully. In the meantime, anyone have any insight or thoughts on what might be the problem? Any and all replies are welcome and appreciated. Thank you!

    Happy Prius-ing

    Hi and welcome to PriusChat.

    I suspect the code reader your mechanic is using is too generic and can see only about 3 of your car's 11-14 ECUs.

    For example, the P3000 is a code which is set meaning I heard from the HV battery ECU that it has a problem. Therefore there should be codes in that ECU that would help in the diagnosis.

    I know you put a new 12 V battery in recently, but please check it and ensure it is fully charged. Prii are difficult to diagnose if the 12 V supply is not stable and reliable.

    Suggest to your mechanic to update his scanner to include Prius PIDs or data files, if that is a possibility for him.

    Keep us updated on how you get on.

    All the trouble might be having, in my view, could be traced to the hybrid battery probably. As long as the dealership were a jackshit, then they could have also extend red that shit, to the HV pack.

    P3000 doesn't tell you exactly what the problem is. There should be a subcode to the code he posted. Without that, we'd be beating around the bush.



    PS: A failing or failed pack, may ha e triggered those codes.

    Im sorry, i dont quite understand what you're saying here. Please rephrase.

    Also, yes my 12v is fine. I checked it in the hidden menu on mfd. And yes, the mechanic told me to take to toyota and have them run diagnostics so we could get a more specific diagnosis. But i dont really have the 140 it cost here to have toyota plug into it. :unsure:

    Check the inverter coolant pump.

    Put car in ready and open hood and take black cap off the inverter reservoir the thin white tank next to silver box . Inside is red fluid. Get flashlight and in ready look in that reservoir and the red fluid should look like it’s boiling from pump movement. If just sitting there the inverter pump has failed.

    Pray it’s that if that’s ok I’m afraid based on what we see here it’s most likely a hybrid battery ground fault. In its beginning stages of failure you can cleAr it’s codes and continue driving. The ground fault is caused by leaking electrolyte coming from failed battery module conducting voltage to ground. Very intermittent than always on. You can confirm this by the picture of a turtle looking car in the upper left corner of the mfd when the codes launch. If you see that turtle along with the red master caution on the dash it’s the hybrid battery.

    Go to Toyota.com/owners forum and join. You will need the cars vin to register so have your insurance card ready. The cars vin is on that card. On that forum You will see every time the car has seen an authorized Toyota dealer for service. You may see why the car was traded in or what exactly was repaired over the years.

    Good luck.

    Thank you for the detailed response. I have already looked at the carfax and sadly, the car was probably not always services with toyota because there is limited service history, and lots of gaps. As for the pump, i can hear it running at start up, and right after shut down, so i dont think its that. I havent checked the reservoir for movement yet but will.

    And thank you foto. I will look into that contact. In pretty sure it is the hv batter, b.c no other lights BUT master warning and hybrid system are on.

    There are several pumps. The one you hear at startup and shutdown is probably the one pumping coolant in and out of the thermos for storage (and that's for the engine cooling, anyway). The pump Ed's referring to is a different one that cools the electronics. It should run pretty much all the time the car is on, but it's pretty quiet, so you can't count on hearing it. Hence looking for turbulence in the coolant.

    You might want to look around the forums here for information on getting Techstream set up for reading your own codes and data. It sounds like you're on a budget, and having to depend on others for checking and rechecking adds up, both in money and time.

    Also, it never hurts to spend some quality time with the New Car Features manual, just so you get basically familiar with what all's in your car and why.

    -Chap

    p.s. Don't try to guess problems by what lights are on. There are hundreds of problem possibilities monitored by the computers, and about half a dozen dash lights. Mention that to a mathematician and she'll probably mumble something about the "pigeonhole principle"....

    Chap, you moved up in my estimation -- of course, you were never far down anyway.

    Make life easy. Contact Matt at Texas Prius Battery Replacement
    legitimate business, knowledgeable, and a respected contributor here on PriusChat. Nearby DFW area.

    Next vehicle you purchase, besides the CarFax, pay to have the vehicle inspected by someone who knows far more than you, about the vehicle you wnat to purchase.

    @LadyLock, don't mind exstudent, his heart's in the right place and I'm sure he means well. Although he comes across abrasive, his motivation is to speak the truth, so that's alright, then. Just needs to polish up his presentation so he doesn't come across condescending and/or insulting.

    Plus check out TSB-0166-09,....you will have to have a few more codes you may not have access to but it may apply as well. Make sure you also try and get the detail or info code that codes with the DTC. If you look at Freeze Frame data on an actual decent scan tool it should give you a P3000 and three more numbers to kind of pinpoint testing.

    Best case you just have a shit auxillary battery.

    Also see if you can check the HV Blower motor that cools the battery. It can be clogged and causing overheating and dummy codes to populate.

    Wow wow wow, thank you everyone for all the responses! Lots to read and look into. But just so everyone is aware, im very much a control freak, plus I just enjoy knowledge. So ive probably read every thread on here with similar problems, every reply, and every solution. Ive also read the entire owners manual on the car, and lots of pdf files found on google and here covering techstream, toyota specific codes, and all the above mentioned. Because i like to already know a little bit about a topic before ever speaking to an expert about said topic, to eliminate any confusion on my part, and to give some level of comfort to the expert that im fully comprehending the information theyre delivering. (Plus it makes for a smoother conversation, the less questions im interrupting with lol)

    So no worries about any replys being taken offensively. I appreciate the level of concern you all have for the other members by insuring they have all the information and advice they could possibly need. Thank you again. =)

    Ive sent in my contact information and current prius situation to texas prius battery replacement, so hopefully ill hear back from them tomorrow and will update accordingly.

    Also, yes the dealer screwed me, but only slightly. I made them include a 3 year/36000 mile warranty on the car, and i dont trust them to actually fix it, but maybe texas prius battery will do the job and bill the dealer with a warrantly claim? If not them, someone else will.

    The P3000 is still, in a way, "hearsay" though. It is a code from the HV ECU repeating that the Battery ECU told it something interesting.

    To get the real low-down from the source, talk to the battery ECU.

    IMHO the proper phrase to avoid extremists is "Mention that to a mathematician and they'll probably mumble..."
    Both gender extreme activists are equally wrong in my opinion. They want superiority not equality.

    Car fax does not reveal as much info as the Toyota forum. And your referencing the wrong pump.
    P3000 is sometimes corroded connections to and from the battery ecu. But no matter what you have hybrid battery issues which means it’s got to come out for inspection. Probably corroded and very tired,
    Like the bulk of posters of late start thinking about what your going to do with it. Replace it or whack a mole module replacement.

    Sounds like an off-topic that could be discussed in FHOP.


    While your first statement maybe true, it could be many other things too. Your second statement is actually all you can certainly say from the P3000 code, because as Chap said P3000 is a code from the HV ECU repeating that the Battery ECU told it something interesting. To find out what that interesting tidbit was, just ask the Battery ECU what's up?

    So now you have a much bigger problem, more information and potentially knowledge, than anyone who is likely to work on your car ;)

    We can only hope you don't get the dreaded "deer in the headlights" look when you question the repair facility about their test results and potential repair paths.
