Prius (2010-12) :: Ready Light Doesn't Always Come On When Power Button Pressed
Sep 4, 2015
This started about 2 months ago. About 10% of the time when I depress the brake and press the Power button, all the dash lights come on except the Ready light (it acts as if I pressed the Power button twice without my foot on the brake). When I depress the brake a second time and press Power button again, the Ready light will still NOT come on. I have to press Power button with foot off the brake to shut off the dash lights (the car is effectively off) and then when I press Power button with foot on brake a second time, the Ready light will come on. I effectively have to try to start the car twice. I also noticed that the interior lights are dimmer when I open the driver's door until it goes through it's normal noisy gyration (something to do with the brakes?). I'm thinking that the 12-volt battery is starting to fail. Does my Gen III 2010 Prius have a diagnostic tool to check the battery?

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.

Since I purchased my 2010 Prius new, it often won't start. As instructed, I press the brake, push the power button for a few seconds, and hope that the ready light will come on. Typically, the dashboard lights up but the ready light doesn't come on. It can take ten minutes or more to get the car started. This happens when the car is cold, or has been sitting for a while, or randomly at other times. The Toyota service department will only address the problem if they can replicate it. I've left it at the service department for a couple of days until they experienced the problem. They reset a computer component which worked for three months. Now the issue is happening again and I'm back to trying to convince Toyota that it's a problem.

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 have both a 2010 Prius and a new v and have just noticed that if you press the 'Econ' button once, the little light goes on in the dashboard. If you press it again, the little light goes off. The same occurs with the 'pwr' button.

I took delivery of my new prius a few weeks ago and of course played around with the parking assist. However in the last few days when I press the button to start the process I simply get a double beep and nothing more happens.
I called the dealer and they don't seem to know what it is and so have booked me in to take a look at it.

The 2010 Prius in our garage would not start today. I tried jump starting it with the 12 volt in our van, but the light on our smart jumper cables would not light up on the Prius side even when I switched them around. I followed the manual's five minutes revving and such, but the ready light does not come on in the Prius. There is enough power for the inside lights to come on, but they are dimmed. I'm thinking we left the lights on in the back seat dome area based on what my daughter told me. The car has not been driven for about 65 hours.

I noticed on the way home the "ready" light was on the whole time. I've never noticed it staying on before but maybe just didn't pay attention to it. Is it supposed to be on continuously? What exactly is it for?

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 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 radio was working fine on Friday, but the next time I drove the car, on Sunday, the radio wouldn't turn on. The power button doesn't do anything, pressing the mode button doesn't do anything and the voice command button doesn't do anything.
Everything else works... bluetooth, display, Nav. Just the radio/CD player won't turn on... it just says "Audio Off". Also, when I go into the diag screen, the Audio reports "NCON". I've checked the fuses listed in the Owners Manuel as audio and they all seem fine.

About once a week our 2011 Prius will start, but the "Ready" indicator does not come on and the car cannot be shifted into drive. Once this happens it takes several attempts, turning the car on/off, until it finally comes on "Ready." I cannot create the problem, but it may stem from pushing the start button before the brake is fully depressed.
Last night it took more than 5 minutes to get it going. I "reset" the car by exiting, locking, and re entering the car. Then it worked, that procedure caused it to work.

Is there a way to have the 2011 RX350 lock all of the doors/trunk automatically when I press the close buton on back of trunk?
Once I press trunk close button on back of trunk, it seems have to wait until it closes before I can lock he entire car and walk away?
If I press the lock button too early, I get the alarm.

Today was a very warm day... I pressed on the air conditioner button.. On the screen it looks like everything is ok.. But actually nothing happens.. The air conditioner is not turning on at all.. What can i do?

The engine starts, the throttle actuates, the dash lights and dome light work, the radio even works, but the fan does not, and neither does the air conditioner.
Turning the fan knob produced almost a whispering whining sound which soon stopped, and the AC compressor refuses to engage when the button is pressed.
One code popped up- P2118. I have read in other parts of the forum that this indicates a throttle actuator control motor current failure, but as I said, the throttle actuates, and the accelerator pedal works as intended. I reset that code, but I'm halfway dreading its return.
