The aux battery was changed about 9 months ago and the only problem I currently have is the tag lights are not working.
Have been having cascading problems since installing PIS 10kWh system in April. Early system shutdown, failed BMS boards, then triggering of Prius warning lights. The latter required disconnecting the 12v battery to 'reboot' and cancel them per Robb of PIS. But then, when attempting to do an electrical load test using air con & other accessories, we triggered several yellow warning lights that do no go away with a reboot. Have been told that we need to have a dealer read the codes to troubleshoot.

I have a 2005 Toyota Prius with about 150K miles on it. After work one night i hit a pothole and my ABS and BRAKE lights came on. I took it to a garage and they could t find anything wrong with it so they reset the light. It came back on about a week later (no potholdes this time) and i took it back. They hooked it up again this time it said there was an issue with the computer coding. So i took it to a Toyota dealership. They hooked it up to all their scanners and could find nothing wrong with my vehicle. They recalibrated the sensor and the light went off. Now a week later it is back on again. Brakes work fine and we get no error codes.
View 10 RepliesThe red triangle warning on my dash recently came on so I am taking it to the nearest dealer on Monday. I think all of this is covered under recalls/warranty. Am I right?
View 4 RepliesI just bought my 2006 Toyota Prius about a year ago in 2009. About a month or two ago, the check engine light came on and stayed on along with a big red triangular warning light.
I brought the vehicle into my local Toyota dealership so they can diagnose it.They told me that they had 3 or 4 different "codes" coming from the machine when getting the signals from the check engine light. All the codes were related to the cooling system. They said that they felt that there was "debris" clogging the pathway for the coolant flow throughout the engine. They had recommended a "coolant flush" for the hybrid side as well as the mechanical side.
So I had them perform the coolant flushes. After leaving the dealership that 1st time, the check engine light came back on the next day. I called the same dealership and explained it to them. They asked me to bring it in again.
SO I brought it to them a 2nd time. They diagnosed it again. They told me they came up with 2 of the SAME "codes" and 1 that was different, but ALL the codes were STILL related to the cooling system. They explained to me that something was preventing the clear flow of coolant throughout the engine. And since the thermostat was the only major obstacle, they recommended that I replace it. Well, I did. And after I left the dealership that 2nd time, I was praying that this was the last of my Prius issues !
The check engine light came back on the next day. The service person invited me back and did not charge me this time because it was the same issue. I told them that I am not in the business of randomly changing parts on my car unless I am absolutely sure I know exactly what the problem is. HOWEVER, this time they kept my vehicle for a good week or two. Running it through various diagnostics tests overnight here and there.
They finally came out and said that they feel that I have a coolant system leak coming from my engine and that I need to replace my head gasket which is responsible for sealing the engine.
During my 1st visit, the codes were P0117 and P1150
During the 2nd and 3rd visits , in addition to those, there was one additional one that came up that I will post as soon as I find it !
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 RepliesI recently replaced my engine water pump at 164,000 miles on my 2007 Prius, the car sat for 3 weeks while waiting to gather needed parts, i.e., water pump, coolant and Airlift system for adding coolant fluid. After installing the new water pump the car ran rough for 5-10 minutes upon initial crank (parked for 3-weeks). I took a 20 minute test drive around the neighborhood that evening, outside temperature around 65 degrees F, and car ran fine. SOC looked ok, bars moving between Blue and Green, everything appeared normal.
The next morning, I backed out of my driveway and the Red Triangle of Death appeared on the dash so I parked the car.
That evening I hooked up OBDII ELM327 scanner using Engine Link and picked up 2 separate P0A80 error codes, 1 of them was pending. I disconnected the Aux battery for 3-5 mins to clear the error's, Red Triangle of Death was cleared, then drove the Prius for 20 minutes with no errors or alarms. SOC seemed to be normal. OBDII ELM327 scanner showed the HV batteries were charging at same level, 16.8V and Aux battery was registering at 14.0 Volts.
The next morning, after 20 minutes of driving the Red Triangle of Death appeared, and shortly after I experienced loss of power, with sporadic engine idle and interior traction battery fan was on. Luckily I had made it to work and was able to pull into a vacant parking lot.
I did notice that around the time the Red Triangle of death came on this morning the SOC dropped quickly to 1 Purple bar and was slow to charge then shortly after came the loss of power and sporadic engine idle followed by interior battery fan.
Had a shutdown with error codes P0078 and P0092 on the scan gauge. Reset the codes with a scangauge and the car goes drives fine. This has not repeated for a couple of days but I was wondering where to see a list of Gen2 codes so that I can better understand what happened.
View 5 RepliesMy son drives our old 2005 Prius with over 300000 miles on it. He had a front end accident a few years ago, and, after body repair and a straightened frame, the car has been running pretty well, although the mpgs have been in the low 30s. This may be the result of his "lead foot." He recently saw the check engine light and the car shows the codes P2601 and P1116.
View 7 RepliesIssues:
1. Getting beeping noise like the keys left in the ignition when the doors open although they are not- battery is good.
2. Red triangle on start up with warning about Transmission- Parking brake does not sensor as being on, when on - in the diagnostic screen.
3. Fog lights are no longer operating when just the parking lights are on, but are when the headlights come on.
These issues may be separate but they all kind of happened in the same time span.
Background - 2009 Prius, Optium Battery initially installed Spring of 2012, over 66,000 miles. Battery is good, all fuses are good.
Since installing the Optium Battery I have had to change the battery about four times - as I am not always driving so I keep a 12v battery on the ready on a battery maintainer just incase I need to change batteries - not optimal, but it works for now. For this reason I turn the SKS off.
Last week my FOB started working erratically for about a week. I would have to press the button several times to get my door to open. Then it started working again like a champ. The battery in the FOB was changed by the dealer in September.
I regularly use the fog lights without the headlights. At the start of the week the fog lights no longer worked with the parking lights and only with the headlights.
Later in the week the car started beeping whenever I exited the vehicle from the driver's side. The beep was the constant short beep like when you leave your key in the ignition. I had not and nothing else was on (I read the post about the guy who moved his car for a family function.) This is an issue I associate with me having to change the battery, however it would have to wait to the weekend and an onboard diagnotic indicated that my battery with load was running at 13.9volts. Every other time I would start the engine I would get the red triangle and retry and the car would start up fine.
I was not able to make it to the weekend to change the battery and had to get a jump to get home on Friday. Upon initial start up after the jump and changing the battery the car indicated that there was a problem with the transmission ... park on flat surface... (Message goes to quicky for me to write it all down and I could not repeat the situation to get the message again).
I got the transmission p lock mechanism error. following the advice of the multiple threads, I removed and replaced the old battery after testing it. I drove about 40 miles and the triangle came back with the vsc and yellow exclamation highlighted too. The cruise control quit working but I was able to get it to the dealership and get a reading. There were two codes: p3102-581 and c2301 -40 and 50. the dealer wants to keep it all day to "dig into it". This is on a 2006 prius.
View 19 RepliesThree intermittent problems with 2012 Prius Two.
1. Backup camera usually doesn't work but sometimes does.
2. Car 3 times has not gone into start when we press brake and power button. All the error lights go on. We keep trying, and eventually, it goes on and the problem does not often recur. The most recent time this was after stopping for a few minutes after hours of driving, so the battery should have been fully charged and everything warm. fter the second problem, the dealer checked it out, said the 12 v battery was fine and couldn't replicate a problem.
3. Just yesterday, with lights and window washers on, only the Ready light, the Gear indicator, and the headlight lamp were on. Everything else on the display was dark. No speed, no gas tank indicator, etc. Turning the headlights off and on fixed the problem for about 5 seconds, and then it recurred. This morning, with no rain and therefore no wipers, there was no problem, with or without the headlights.
My cars been stalling , won't drive up hills can't really get over 25 - 30 mph and I'm getting a sound from the fan in the back. These 3 error codes could mean for my 2007 Toyota prius
View 19 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.
ok scan system for code with Snap On verus and a Launch x431 this is a 2005 with 192k. I can not find any inf codes to lead me in the flow chart that alldata provides. Are their some years that don't provide inf codes. I have check all 3 smi relay and they are getting the command signal to closed the relays but looks like the smi2 will not close at times can this be the cause of poaa6 of the isolation fault. seems to be intermittent sometimes it closes. As far as the poaa6 I did push the start button 1 time to power up with no not "ready" on and waited 90 seconds and the triangle came on and set code. It has a new 12v battery I have take all the buss bars off the hv and clean, not that bad very littler discoloration and corrosion. Test each cell and have 7.78-7.97 in each ,installed 55w light loaded each and none ever drop below 7.65. this my not be the right way but I am learning and trying to figure this out. Have really never worked on the hv side of a prius always the motor side, but this now intrigues me .
View 9 RepliesI was driving my 2008 Prius and it abruptly slowed down and became undriveable. I had all of the warning lights - the red triangle master warning light, hybrid syatem warning light, and the check engine warning light. The car had to be towed home. The gas engine starts and runs - driving forward feels like the brakes are on - will not drive in reverse,. I checked the codes and had the following : POA1D, POA78, POA90, and POA94.
View 2 RepliesI'm rebuilding the traction battery on my 2006 Gen II Prius. When completed, I'd like to erase any "error codes" that should be erased (I don't even know where these might be), and turn off the red triangle of death, the VSC light, the (!) idiot light, the engine check light and the maintenance required light.
View 6 RepliesSo I have MFD display errors for "main beam not working" on both sides but both of my headlights, lows and highs both work fine. this has been like this for a few months now. I can clear the codes with my VAGCOM and after a day or two they come right back. I do have LED license plate lights but for at least a year i only got the error code on startup for the plate lights but never headlights. A little confused as to what is tripping the headlight codes
View 3 RepliesMy car was working fine except for occasional no dash lights. Unfortunately where my dash lights don't work sometimes I can't see my gas gauge and I ran out of gas today. I manage to make it to the gas station on battery power I presume. Filled the tank up with 11 gallons and the car seemed to work fine for the remainder of my trip(about 5 miles). So I parked at my destination and went inside for 30 minutes and then I went back out and started the car. I attempted to clear the out of gas error code and all of a sudden a whole Christmas trees of lights popped on my dash. I rescanned and these codes were read out

History : I had the coolant pump inverter changed 2-3 months ago by a mechanic and hybrid battery and battery ecu changed 2 years ago by myself.
2005 Gen2 with 216k miles
Driving on highway and accelerated to pass a vehicle, sudden slow down and all warning/error lights went on. Pulled to side of road and used Autel 539 to get codes P0A78 + P0A90. Scan code reader does NOT display the INF codes, so I can not get them.
Turned off vehicle and restarted. Put into drive and it appeared that I could move forward (and reverse) and was apparently running strictly on the ICE - no power coming from the DC motor for assist. HV battery would charge as driving down road.
It was slow moving, but as long as I was accelerating (very sluggish!) was able to move forward. If I took foot off gas pedal then ICE stopped running and would not restart when pressing on gas pedal.
As far as the owner can tell, the car is running fine. He hasn't driven it aside from getting home after the light came on. It seems to give a very informative error message. What it's saying?
