Prius (2010-12) :: Reverse Polarity Jump Start - Power Button Blinks Orange Never Goes Green
Jun 19, 2015
THE PROBLEM: Our Prius 12V aux battery died after my wife left the light on inside the car and instead of buying a new battery, we decided to try jump starting it. My wife tried jump starting our Prius with the neighbors pickup truck and even though I wasn't physically there to witness it, I'm pretty sure that the polarity got swapped during the process. It wouldn't start afterwards, so we went out and bought a brand new 12V aux battery. The prius still will not start. No electric components seem to work (door locks, back brake lights, windows, radio don't work). The dash only shows the orange exclamation mark and the check engine light, nothing else. The power button blinks orange, never goes green.
TROUBLESHOOTING that I've tried:
1. Checked the big 120A fuse right on the positive + terminal. Visibly looked good.
2. Checked all the fuses by the drivers left knee. All tested good with resistance + visible checks.
3. Checked all the fuses in the fusebox under the hood. All tested good EXCEPT the big relay integration fuse under the white plastic cover. It was definitely blown.
4. Replaced the relay integration, still no luck, same exact symptoms.
5. Tried force starting the car in emergency mode by holding the brake and power button down for 15+ secs. The engine starts, but the dash is still dead showing just the check engine light and orange exclamation mark. Can not shift gears or drive.
6. Tried slow charging the NEW battery to get the voltage higher, still no luck. It's testing about 13V with everything off.

I kept my car more than 6 days in my garage and today I tried to start my car but, unfortunately smart key did not work. once i kept my hand under the door handle i can here a small click noise but it is not the usual noise and the turn light even did not flash, still the door is locked so i tired to unlock with the mechanical key. Then I enter to the car and i press the break paddle I heard a long motor noise as usual but this is bit longer noise. then i saw my smart key appears on the dash board but the car did not start up . again i tried to on the car I here a knocking noise and the green light on the power button blinks. I tried several times no luck. what will be the problem will it be 12v battery?

My Pris 2010 would not start this morning. My wife tried to start the car this morning and it would not start. All the symbols on the display light up and would not go. She then tries to turn off the car, but the Triangle symbol with the exclamation mark within it lights up. The Start button light is red and the Park button flashes green. Added to that is the constant beep that you hear when you try to close the door with the keys in the car. I cannot even turn the steering wheel. I had to get it towed to the Toyota dealer and am was told that i would hear back tomorrow.

I have a 2005 prius with 38,160 miles I started it and shut it off and then tried restarting and now does not want to start. The ready light does not go on and the start button becomes orange.
I checked my 12 volt and it gave a reading of 12.2 volts. These are the engine codes that come up:
U0111 comes up twice
C0200
C1259
C1310

I've got a 2010 Prius w/ NAV. Yesterday morning, my Prius would not start. When I pressed on the brake, the green "Ready" button would not light up. When I pressed the start button, the NAV screen came on as did some of the dash lights, but the car engine itself was not on. When I hit the start button again, I had a yellow triangle on the left side of my screen that continued to blink.
From reviewing the forum, I believe that the issue is the 12V aux battery. I was able to get my car into maintenance mode, and the 12V battery was reading 8.6V; however, this was after my car had sat in the garage for 10 or so hours. However, by going into maintenance mode, I was again able to get my car to start. This morning, I drove my car to work (about a 15-20 minute drive). After I got to the office, I turned the car off and got back into maintenance mode. This time, it was reading 11.6V on the battery.
Am I correct that this is most likely an issue w/ the 12V battery going bad on me? I purchased my Prius in July 2010, and I have never changed the battery. It sounds like the "typical" lifespan for the battery is right around 4 years, so this seems to make sense.

After letting the car sit unused for about 4 days I now find my power button LED is orange not green as always. The display showed the main battery down to two purple bars but after a short drive its returned to normal.
The 12 volt battery is at 12.9 volts and everything else seems normal.

I put the key in. I hit the Power Button. The light in Power Button turns orange. The car doesn't start. The key can't be removed from recepticle. The following message comes on the screen: "Caution: The transmission lock mechanism is abnormal. Park your car at a flat place and apply the parking brake completely." (Except it is already parked in a flat place with the parking brake completely on).

I'm parking the car (gen. 2) a long while, so I checked the manual which shows the deactivation button on/off positions. It show the button sticking out more = the off position. However, the car symbol still blinks on the dashboard.

I have a 2013 Prius Three. If I drive somewhere (engine completely warm) and stop, like at a store, come back 5-10 mins later, hit the power button, sometimes the ICE will start and immediately shut off, like within 1 second. It can't be the warm up cycle as the ICE is at normal operating temperature. I guess it is not a issue, as one of the 20 computers is doing this and there are no lights(like cel).

I have a 2010 Prius that I bought in January. No problems until this morning. Here is the situation...
I get in my car, step on the brake, mash the start button and nothing. The green ready light does not come on, no key detected does not come on, nothing. However, if I take my FOB, and place it by the start button, the ready light will come on and it will start.
I thought it could be a battery issue but, this happens with both FOBs...

My defrost button blinks for 25 seconds when I start the car. After it stops blinking the fan comes on but I won't defrost the front windshield, air only comes out the side vents.

I haven't been able to successfully jump my 2010 Prius. It sat for about a month and the 12v battery is dead. I've connected everything up as described in the manual. I've kept the second car at about 2K RPM for about 5 minutes to charge the Prius. I am able to get the Prius to start up just fine, but as soon as I disconnect the jumper cables, it dies right away. I've tried getting the Prius engine to come on for several minutes, but as i understand it, there's no alternator, so that's probably not charge the 12V battery.
I've gone through this cycle about three times now with the same results. Every posting I've seen doesn't indicate anything special needed after you disconnect the cables. Is there something I'm missing?

So, I was about to go get something in the garage yesterday and the car didn't open. I know one of the fobs has a bad battery. Well I got new batteries and replaced them in both fobs.
Red light blinks can't unlock when clicking the unlock button nor does the smart function work. I get the little key out and open the drivers seat and think Shouldn't there be some lights on in here like around the power button? or blinking?
Usually when you unlock with the little key should you be able to turn lights on inside the car?

With A DeWalt 12V Battery....
I left the hatch up for a few days because I didn't drive it due to hot weather. The battery died on me of course. The dead battery measured 6.59v No amount of "battery recovery" time is going to recover it to start up the Prius. I charged up an old DeWalt 12V NiCad battery. I jump started the Prius with it. When I power down the Prius, the interior lights went back to really dim.

I am wondering how does the jump start works on the Prius since it uses a electric motor to start the engine but not a conventional starter.I recently drained the 12V battery (left the interior lights on for two days) and had to take the battery out from the trunk to recharge it. Initially, I tried to jump start it at the specific jump port at the front of the car but it didn't have any effect at all. By that, I mean as if there was no external power source given to the Prius - i.e., no lights came on and no response when pressing the Start button.
I mean zero electric current at the Prius. Is the electronic starter motor power driven by the hybrid battery? If that is the case, it may explain why jump start didn't work in my case because it only passes the power to the 12V battery which doesn't drive the electric starter motor. So what good is the jump start for if it doesn't work like a conventional car? How this process works on Prius?

The 12V battery must have been drained completely over the weekend. None of the lights (interior and exterior) are working. The car won't start even using jumper cable. I guess the 12v battery must have some juice remaining to power up the computer in order to jump start the engine. Am I correct in this assumption?
My Prius is only a little over three years. What is the warranty on the 12v battery? I read that the OE battery is not the best. How long would I expect the OE 12v battery to last?

Today I replaced my stock 95 Civic headlights with brighter (more white) halogen bulbs. The installation was fast and easy, however, I've noticed one problem after the installation; the remote power locks are no longer working. The car remote still flashes green when I press the button but I get no response from the power locks.
Because of this the alarm no longer activates when I lock my car from the remote. What could be causing the issue? Are the lights taking up too much power? Do I need a better battery? The lights are a big improvement from the stock lights however its very important for my car to be secure. It's been broken into twice, thieves love to target old Hondas...

Have a 2001 Prius going strong except for the ac. The button light blinks on the ac switch, and the compressor seems to shut off. But some times the ac works fine.
I brought it into the dealer and they said I need a new compressor.I think it's a temp sensor, otherwise, why is the ac nice and cold and can stay on for some period before going off.
