Prius (Gen 3) :: Ready Sign Stays On, Car Won't Start
Jul 31, 2013
This is probably the 4th time this has happened, but when I first get into the car this morning, and try to start it (firmly pressed breaks down, waited a second, and pressed the start button), all of the Prius electronics would fire up but the Ready sign would not turn on. Also, with the foot still on the brake, the LED light on the power button is green. When I take the foot off of the brake it's red/orange. With my foot on the brake, I tried to press the start button again but nothing. So I took foot off the brake, hit the start button to turn off the vehicle. Went through this about 2 more times before the car finally started with the Ready sign lit up.

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 recently changed out my 2006 blown gas engine with a great running 2008 engine and also replaced the hybrid battery. After connecting everything, my car won't start. All the lights come on except for the ready light. Does something have to be reset?

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 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...

I have a 2006 Prius that is giving me fits. The car is equipped with the smart key but it seems to be working normally. I insert the key, press the brake, and then press the power button like I am supposed to but the "ready" light doesn't come on and the car won't start. I checked the brake light switch and it is working correctly. 12v battery is charged and shows 12.35 volts. I have been tinkering with the car for the past three days and have only gotten the light to come on and the car to start twice out of the numerous tries.
The last time it started the dreaded "triangle" and check engine light were on so I plugged my scanner in and got code P0A1F, I had a spare battery ECU so I replaced it, while I was at it I removed the battery and cleaned the terminals, there was only a very small amount of light corrosion on a couple of cells. All cells tested good and had uniform voltage. I haven't gotten the car to start since putting everything back together. I have a small amount of experience with these cars but I've got alot to learn.

It ran out of gas with the previous owner and they say the steering is new and the hybrid battery is new and the 12 volt is new but when I got it I had to get the 12volt battery trickle charge which it charge to 80 percent and it still didn't start only goings from lock, acc, then on never say ready no sound but when I pull the IGCT relay the fans come on but it don't start what is this relay?is this car just like Toyota primis. What could be the problem of this mechanism to get it running I have the only one in my town which no one knows how to work on It.

As the weather has gotten colder (32F +/-2F in the morning), my car is not going into ready mode as consistently as it was in warmer months. I also notice that I have a much better chance of success of going into ready mode if I let the car "pressurize" for about 10 seconds prior to pressing the power button (pressurizing = whatever is going on when you open the driver door and you hear the electric noise of something working (brake pressurization) in the front of the car that runs for about 10 seconds).

I have a 2004 prius that sat for 2 years, I just replace a cell, worked on the HV battery and made sure it was balanced. I got the battery back in and I can't get it to go into Ready mode, I can get it to ignition on and charge the battery and into acc. I've checked several components to see if they were causing the issue.
- 12v battery is good
- brake light switch seems to be good as the lights come on when the brake pedal is pressed (but ready mode does not)
- I've checked a number of fuses
- used and obd2 adapter with torque and it is not coming up with any codes
-Edit-
- 12v battery was replaced last spring and has been maintained

Basically, every once in a while the car refuses to go into "Ready" mode - it acts like you are trying to start it with your foot off the brake. Appears to be getting worse over time. Happens at least once a week. Yesterday I probably tried to start it 30 times before it finally took. Once it gets going it is fine, and often it will start right back up several times before it starts acting up again. No rhyme or reason to it.

When I put the car in ready, the car will beep 3 times. It's like, foot on brake and press start button, then car shows ready, at the same time it goes chirp-chirp, then beep beep beep. I'm just wondering if the 3 beeps can be turned off? I didn't find any thread regarding this beep. I did find many about turning off the seat belt beep, reverse beep, etc. and I already turned off those beeps.

My 2005 Prius won't go into READY mode. This has been happening for many times now almost a month. Up until today if I let it sit there for a while (sometimes a couple of hours) it would work eventually, however, starting today it just does not want to go into READY mode. One thing that I have noticed is that when I press the brake pedal the brake lights do not turn on. I have been suggested that it could be the Stop Light Switch that causes it, and one way to check was to perform the following procedure:
(1) Push the P position switch.
(2) Parking brake pedal is depressed.
(3) Turn the power switch from off to on (ACC)
(4) Brake pedal is depressed.
(5) Press and hold the power switch for 15 seconds or more.
According to Vincent if this starts the car then it is the Stop Light Switch but I was not able to start my car even with this procedure (may be I am doing it wrong.
Note: I have checked the 12V battery and it is not the problem.

I measured battery on my 2007 Prius by MDF, it's only 11.9V, charging is about 14V. When I turn on ACC mode, and Radio is on, I think it shut down the radio after about 15minutes; I cannot put the car in ready mode after it shut down. I have to jump it in order to put in ready mode. Is it my turn to replace this auxiliary battery?

Is there a way to open the back door while the car is in ready? I don't thing there's a trunk release or the equivalent & touching the handle on the back doesn't work until I turn the car off.
Obviously, this is a good safety feature, but I'm wondering if there's a way to open the trunk without turning the engine off since 6 months of the year I keep the heater running in the morning as we're getting ready to leave the house (-14C or 0F forecast tonight, or what we call "spring weather").

2nd time I've had this problem. With the car turned on "ready light" on, the car will not shift into D. It just stays in park, and yes my foot is on the brake. I've tried to reset by turning the car off, turning it on again and shifting into D, still no luck. By retrying this over and over it finally goes into Drive and away I go. I've had the car for 3months and 5k miles, and this has only happened twice.
The second time occurred when I was stopped by a flagman at a road construction site. Instead of shutting down, I just pushed the park button. The lights were on, the radio playing and my garmin was plugged in and the AC was on, would the high load have caused the problem? When I pulled the plug on the Garmin, the car went into gear on the next try, but I don't know if there is a cause and effect. I finally got it going after about 25 cars had to go around me and the last car was passing me when it finally went into D.

2011 Prius with 30,000
At the first start of day when I pressed on brake pedal and got the green light on power button as usual I pressed power button and never got ready condition, trying to figure out what is happening I have had this condition occur almost every morning (outside air temp around 40 degrees F) also when I went to train station to pick up my daughter I shut off for about ten minutes and it happened again.

When I backed up yesterday, some dash symbols showed up. After turning off the car, I am not able to get it in Ready Mode. Only solution so far: to disconnect the 12V battery and wait approx. 2-3 minutes. After that, the lights are off. The 12v battery does also indicates normal voltage. IG-OFF: 12.7V IG-ON 12.2 ... Unfortunately I cannot get the trouble codes with my scan tool ...

I have 2004 Toyota Prius 110k miles on it. New auxilary battery on it. VSC, Brake and Red triangle lights are on. The car wont start. System comes on, but ready light doesn't not appear.
If I discoonect the battery for a minute and connect it back, I am able to start and drive it. After a minute VSC, brake light comes on. I still can drive the car and it drives perfect. As soon as I shut it off, I won't be able to restart it again. I have to disconnect the battery for a minute to get it started. Inverter pump seems to be working fine.
I got the codes with the paper clip VSC 43, Brake 36. After resetting the codes, I drove the car and now it throws VSC 51 code.
Check engine light is not on. When I checked with OBD scanner, it does not show any codes. When we checked with shop's scanner, there was a code smth "LOST COMMUNICATION WITH HYBRID..."

I replaced the HV Control ECU on my 2007 Prius, because my coding scan read POA1D. Now the lights on the dash all light up, but the Ready light does not come on.

So I use my car as a "work truck" and part of my duties involves stopping at a number of houses(8-12) for 5-15 min at a time and then driving 2-6 miles to the next house.
