I have replaced the Traction battery AND the 12volt battery. I clear all codes by disconnecting the 12 volt battery for a short period of time. I reconnect 12v battery and no warning lights. I drive for 10 miles and RED TRIANGLE, Check Engine and the Brake lights also come on the dash. 2006 Prius 130K miles.
View 16 Replies2005 Prius I picked up a few weeks ago decided to eat both of it's batteries for lunch and leave me high and dry. I replaced the aux battery yesterday which I was lucky to get at cost at the toyota dealer since the aux battery was original. Put it in and all was well with the car for the rest of the day. Got in it today and headed out and was welcomed with the big stupid "!" triangle, the regen brake warning, check engine light, "PROBLEM" written on the display with a picture of a "!" inside a car outline, and some severely reduced performance. So I looked online and found a place with a bunch of low mileage batteries out of smashed up 2009's.
View 19 RepliesI have a 2007 Prius. We left for vacation for 2 weeks. Came home. Started the car and then all the lights came home. I thought the battery must have drained. But the lights are all on with a new battery. Is there a way to clear all these?
View 8 RepliesMy 2007 Prius suddenly lost power and all lights on the dash board light up. I had a "problem" error as well. Eventually a message came up stating there was a transmission P lock mechanism problem.
Long story short, realized the 12volt was dead and replaced it. However, the car is still not running after replacing the battery. It went once around the block fine, and then the same thing happened with all the lights (check engine, VSC, brake system, and !) and P lock mechanism warning. Disconnected the battery for 15 minutes and tried again. No luck.
2006 Toyota Prius 93000 miles
On 3/8/13 my Prius would not start. I read some information online and came to the conclusion I needed a new battery.
I started the car, and it immediately started up. I drove it for a very short time and parked it in the garage.
Today I started the car and drove it for about 5 minutes to a restaurant. I did some shopping and about 3 hours later I started the car and A Big Red Triangle appeared along with a yellow circle with an exclamation point in the center and the check engine light.
I immediately drove it to the Toyota Dealer 5 blocks away.
I've seen lots of posts about the traction battery regarding cooling fan speeds, sensors, overheating, under charged, but is there a dash light that warns the batteries are overheating before they are damaged ? I'm worried about someone riding in the back of the car, covering the vent and causing battery damage. It is hard to see if they are covering the vents when you are sitting in the front driver seat.
View 7 RepliesStarted my 2010 Prius the other day and the traction control, brake light, abs light and a yellow Astrix light came on and wouldn't go off. The car drives and handles just fine, brakes feel normal. I have tried resetting the lights with a trick with a paper clip someone else posted, but it didn't work for me.
View 7 RepliesI bought two new factory fresh speed sensors to replace the ones. So, after work tonight I get the car up on jack stands and replace both sensors in about 45 minutes. Get it off the jack stands, torque down the rims and reset the dash lights. Nice clean dash display with no warning lights.
I drive it down the street, nice speedometer display and then, after about 100 yards, the warning lights come on and the speedometer flickers from 22mph to 2 then 10 then 1 then zero. I drive it back home, check the sensors and the connections, reset the lights again, drive it down the street and, same story.
last week I got a whole array of warning lights, including the triangle of death. Took it in to my local mechanic who diagnosed it and told me it was the HV Battery. So, as a temporary fix, we did some DIY and just replaced the bad cell. Everything went well, just some minor troubles toward the end with the engine not turning on, which we fixed by switching the orange switch on the battery and disconnecting and then reconnecting the 12V battery. It was driving great, until u got to work this morning and all the lights came on again. What am I missing?
View 13 RepliesTested and replaced 2 bad battery cells in my 2007 Prius... Got everything put back together and now all dash lights are on and engine won't start... When i try to shift into drive or reverse it goes directly into park... I tested the battery without removing the safety key and the inside terminals are at 220 volts and the outside terminals are at 0 volts as shown by photo... Maybe due to a fuse somewhere?
View 19 RepliesTonight I was driving home and the warning light came on. Thursday I was driving and noticed that the power lurched a few times. I switched over to see the energy usage and noticed that the battery was at the lowest bar. It stayed there for about 10 minutes. I called the dealer and started to head there. As I was talking the bars began to rise. It has seemed fine for the last few days until the lights came on tonight. I had just put gas in it. However, the car seems to run just fine and the traction battery seems to be charging just fine. There was no loss of power. Here in Texas it has been over 100 degrees for many days. I had an oil change at the dealer 10 days ago.
View 4 RepliesI have my 2004 Prius in the shop for a replacement of the HV battery pack. The car has approx. 120,00 miles on it.
The battery failed with all the lights, warning symbols etc. I just got a call from the dealership that its going to take longer than expected to get the car back to me. They have the battery pack replacement, but when doing the replacement, they noticed that the cables were "corroded." The cables for the battery need to be replaced before they will complete the repair. But the cables need to be ordered and won't be in soon.
Is this common? for these cables to corrode? Would this problem have caused the HV battery failure?
I have a 2007 Prius with 92000 miles. All dashboard warning lights lit up the other day. Had it towed to the Toyota dealer and they first replaced the HV ECU. Now they are saying the traction battery needs to be replaced. They have had the car several days but they put me in a free rental.
View 3 RepliesGen II Prius, 151000 miles, HV battery died (rapid charging / discharging, cooling fan on high constantly, etc) Installed remanufactured HV battery. Connect it all back up, test drive, get the triangle of death, VSC, amber (!), and MIL on MFD. Car continues to drive normally until shutdown, upon next startup lights still present and won't shift into D or R only N. Pull codes, POAA6 is showing.
Code doesn't reset with car in ign on (not ready) after 60 seconds, make car ready and shift immediately to N. Code resets after 30 sec. Have done this trouble shooting 4 times and code always resets with ready on and in N. This points to the HV 'leak' being either in the wiring harness or the inverter. What I can do next in order to figure out which one?
A year and a half ago, I had the hybrid battery warning lights come on and had it towed to the dealer. After given the option of replacing the battery for $4300, I took it home and did a single cell replacement (all cells ~8V, one at 6.6V which I replaced), which seemed to be all good until yesterday. Back with the warning lights and blower fan, I jumped to the conclusion that I have a similar situation, removed the battery and all cells are 8.04V +/- .05V except for 1 cell at 7.92. I am not convinced that this cell is really the culprit.
View 11 RepliesI had noticed a drop in MPG in the last month (more than normal this time of year), so I started searching on PC. That lead me to testing my 12V battery 4 days ago, with the following results:
No load: 11.8V
Load: 11.5V
Charge: 14.2V
Car started and ran fine, but since the battery is the original on my 2006 with just under 130,000 miles on it, I figured I'd get a new 12V the next time there was a good deal at Advance Auto. No other symptoms until today. After driving around 150 miles on Saturday, the car sat for 3-1/2 days in 25-40 degree temperatures. Started and ran fine today. Did a 5 mile trip, followed by a 1/2 mile trip, followed by a 5 mile trip home.
On the way home, the car lit up like a Christmas tree (appropriate for this time of year). Master warning light, brake system light (yellow; not red), check engine light, VSC light, hybrid system light (no ABS light). Turned it off and restarted and the VSC wasn't lit, but everything else still was.
More info... I finally got around to disabling the back-up beep, and the driver side seat belt warning yesterday, which may have run the 12V down even more.
Well all the lights are on for mine as well as of 2 days ago... checked the 12v, was at 11.8v, tested under accessories load (without engine on) and went to 11.4v then tested with the car on and we're at 14.2v
So just to be safe I went ahead and got a NEW 12v and installed it yesterday. All the lights went away immediately. Drove 30 minutes to the town over after the install... fine.... it sat off for about 1 hour.... drove it back home another 30... perfectly fine.
This morning the wife takes it to work, starts the car, all the lights on again... turns it off completely, then turns it back on and all the lights are off and then drove it to work just fine.
I bought a 2006 Prius with a diagnosed bad battery and tons of warning lights lit on the dash. Toyota had diagnosed a bad hybrid batt and ECU. (I have not replaced the ECU). The car was driving and running fine otherwise.
View 12 RepliesI own a 2005 Prius with 233K miles. I got the terrible red triangle of death and several other warning lights. Had the codes checked out at Toyota and confirmed a bad HV battery. I am kinda handy and I replaced it myself. No big job, it took about two hours, most of which was spent removing the interior panels, etc. Test drove the car and all looked well. Thirty or so miles later, BAMMM, lots of warning lights. At this point I took it to my mechanic to have it checked out. They found nothing you wouldn't expect when you've disconnected the two batteries.
They cleared the codes and off I went. Again about thirty miles out the lights went on again. Back to the garage once again. What they found was a corroded connector running to the fan, located under the rain gutter of the hatch, passenger side. Hmmm, how'd that get corroded?? Two years ago I remember drain the sump where the spare's located of 6 inches of water, how'd that get in there??? My mechanic confirmed he has seen that before in the Prius. So now I am wondering, did the initial battery fail because the fan may have failed??? Perhaps we need a warning light.....
Some years back my "farm" '05 prius when a host of bells and whistles went off, cooling fan ran more than normal, and I lost power a couple of times. Turned out this farm prius had an accumulation of dirt, dog hair, hay and other debris that needed to be cleaned out. You got me through the whole process, and the car's run fine until.... . Fast forward a couple of years to 200,003 miles. Now the cooling fan is running pretty constantly, the red triangle stays lit, the check engine light comes on, the (!) is on, and the VSC light is on. Haven't hooked it up to check codes, but did check cooling fan and it's clean. Would it possibly possibly better to change the 12 volt battery?
View 19 RepliesThis morning after starting my accent the abs, e-brake, and traction lights all came on. What could this indicate, and should I not drive the car till it is fixed? I checked brake fluid levels for the of it, and they were fine.
