Prius (2004-09) :: VSC Warning Light Came On After 12V Battery Replacement
Jun 17, 2015
My 12v battery died, I tried recharging it etc, but it was dead so I took it to my local Toyota dealer and had the battery replaced.
Because I had the battery off, there was a VSC warning light, which I thought that the Toyota dealer could reset. They re-calibrated all the warning apart from one, they say that the Yaw sensor will not clear it's warning and needs to be replaced.
if I can reset this warning myself, or do I really need to replace this sensor?

I just purchased a 2006 Prius with 89k miles and it has a problem with the drive train and randomly losing all power on the freeway causing me to make emergency shoulder stops to reset the car.
The symptoms are as follows:
-red triangle on, orange circle with ! on, check engine light on, hybrid monitor green car symbol is red with ! in it
-traction battery fan is always on when car is powered
-the car has never driven under electric power
-shifting problems, sluggish acceleration and all power loss on freeway
-hybrid monitor system lies and shows the battery full one second and empty the next.

I replaced my hybrid battery of my NHW10 a year ago. now recently it shows the warning triangle. Once it went off after a long drive but now its permanent. is there a way to Diagnose what is the cause of this? If its a Hybrid battery issue, will it go off if i replace the bad cells?

In my one-owner purchased-new 2005 Prius w/ 74K miles and w/ no maintenance/accident history other than doing all scheduled maintenances at Toyota Dealers along w/ recalls applicable at each time (other than we had Toyota replace the 12V battery last year just because I knew it would die at some point anyway and I don't like pushing my luck; I'm not 100% certain if there's been a recall on any water pump for this car and if so, don't believe the dealer has mentioned it), I have the following indicators which appeared all at once while I was driving along at around 45 MPH in no unusual circumstances (80F, dry afternoon, about 30 minutes into a trip of mixed speeds, no loads in the vehicle, no effect on the car while driving):
From Left to Right on the display:
1) Red Triangle - Master Warning Light
2) Orange (Symbol)CHECK - Malfunction Indicator Lamp
3) Orange (!) - Brake Warning Light (but it didn't highlight the word 'Brake' in red)
4) Orange VSC - Vehicle Stability Control Warning Light
On the Screen:
Orange Car w/ the ! symbol - Hybrid System Warning Light
We immediately aimed for the house (about 5 miles away); the car drove perfectly fine, with the engine stopping and starting at lights as needed, with speeds going from the 55MPH we were traveling at the time of the alarms down to 0 and back up thru 35/45 MPH and such per normal off-interstate driving. The battery currently shows all the blue bars, and the engine and hybrid systems showed charge/discharge as usual as we drove. There was no discernible change in the driving reaction of the car to brake, steering, accelerator, etc.

I have a 2004 prius that had a HV batyery problem. HV battery was rebuilt. After that car started ran but after shut down it will not start. It will only show red triangle, abs, vcs, yellow tire. Basically all yellow lights on dash board except check engine. Also on the MFD it shows the red car with exclamation symbol. I scanned it but shows no DTC codes.

I just replaced my 12V battery and now the car won't start. It will take a jump and show "ready" on the dash but as soon as the car is turned off, it won't start again - no lights, nothing. I checked some fuses and they looked fine.

But while driving the hybrid warning light turned on in the MTD. A red car if I remember correctly. It was the hybrid battery over heating and to try and mess with the wiring going to the cooling fan in the right rear quarter panel.

I'm getting the 14 blink code on my Hymotion LED indicating that my 12v battery is needing replacement. My question is that the car seems to run fine with the exception of my mileage is low. I'm ordering the Optima replacement. Can I still drive around for another week without worry?

2005 Prius, 90k, original battery I think, started beeping on shutdown, then wouldn't start today (cold). Got a new battery, but the back hatch wouldn't open, so I tried to jump it following owner's manual instructions. Headlights came on at first (although stalk switch was off), but doors/car wouldn't respond. Disconnected and reconnected jumpers, lights off this time, still no response when trying doors or starting car.

I have an 05 Prius which had no significant problems until the HV battery died this past Feb. Two days later, I'm on the highway and lose power, manage to get the car to an off ramp. Have it towed to a dealer where the power failure pulled up code DTC P3190 and I was told that the car was simply car out of gas. The car was at 3 pips without any indicator going off but after consulting this forum I thought "Okay, maybe this is just the new normal." Filled my car with 5 gallons worth of gas which topped it off (?) and went on my way.
I'll add here for lack of a better place that with the new battery the car has not ever seemed to accelerate cleanly - always feels like there's some resistance on the accelerator when trying to go above 50 on the highway.
Cut to yesterday - I lost power on the highway 3 miles from home with the car at 7 pips (!). I had only put 130 miles on the car since last filling the tank so I can *not* imagine this is a fuel issue. And, worse than ever before, this time when the engine failed I had only about 1000 feet to get over to the shoulder. I did manage to get over safely (for those in SoCal, this was on the 5 North and I narrowly missed blocking the ramps to the 134). To make matters even worse it rush hour in 95+ heat, and I was pinned in my car for 20 minutes (traffic on one side, retaining wall on the other) until the tow truck arrived. I cannot have this happen again.
I had the car towed to the dealer this morning. When the car was picked up the car was at 7 pips in my driveway. The dealer states when the car was dropped of there it was at 1 pip, and sent me a picture of the odometer to verify. Wth?!
How is this possible? How could the gauge have dropped so rapidly? Is there a legitimate way the fuel indicator could have dropped so much or is the dealer scamming me? And what could be be wrong? The AAA driver this morning said they should have replaced the accessory battery when they replaced the hybrid battery, and perhaps that was the source of the problem?

2005 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.

First a little background on the car , it has 217,000 miles. The battery was just replaced with a used one. While taking it through the carwash, she put it in neutral and a minute or two later she got a warning that the battery was not charging and to put it in gear. Sounds like the battery is having issues to me. She has a 60-day warranty.

I 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?

My 2006, with original 12V battery, finally failed to start. It was stone dead. I've been expecting this for awhile, given the age of the battery, but so far it has exhibited no warning symptoms. It was just stone dead in the garage, having not been used for five days.
I used my jump box, which I keep in the back of the Prius. Everything fired up without a hitch, other than the alarm going off when I applied power (rather loud with my head under the hood.)

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.

Well, just replaced my HV battery, hooked everything up (I think) and tried to start it. ALL the caution lights came on and stayed on. This is the code that showed up on the reader. P0AE0. The battery was refurbished and I changed over my Computer module and the contact posts. Everything is tight, and I compared my pre-takedown pics to the post-repair work and it all looks correct.

A few weeks ago, I received the triangle light in my 2007 Prius with 125k miles on it. When I took it to the dealer, they said that the hybrid battery needed to be replaced. A new battery was ordered & installed by the dealer, which took a couple weeks as the battery wasn't in stock. When I picked up the Prius this week, within driving it a couple miles, it was apparent the A/C wasn't working. I took it right back to the dealer who said they'd look into it. When the Service sales guy started it again, it made a very strange noise as well, which it never did before. The dealer has come back and said that not only has the A/C Compressor out but the ABS actuator is also failing. They are saying this has nothing to do with the battery replacement but both these items were working fine before having the battery replaced

I turned on my car this morning to find myself faced with a variety of colored lights, including a little red car on a black bar on my MFD. Drove straight to the dealer and received word that the car was throwing codes P0A80 and P3023 and they recommend replacing the hybrid battery. I have a 2006, have done all the recommended maintenance at the dealer and it has about 133,000 miles on it.

My 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.

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.
