Prius (2004-09) :: 2006 - Ready Light Not Coming On And No Start
Apr 16, 2011
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.

2007 Prius
I just replaced the 12V battery with an Optimus yellow top. The car still will not start. All dash lights come on, READY light does not. Car will only shift into Park and Neutral.
Battery reads 12.6 volts when not hooked up and 12.3 when cables attached to terminals.

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 most recently drove my 2006 Prius around on Saturday Feb. 1, with no problems at all. I went out of town for a couple of days, and returned this afternoon to a car that will not start. I stepped on the brake, pushed Power, and things lit up, the "Ready" light flashed a few times but then went off. Power button light stayed orange.
Several warning lights on dash stayed on (!)/ABS/VSC/traction control, and a message came on the screen saying something about a problem with "P" parking, and that it should be parked level and the parking brake applied. It is sitting level with the parking brake applied already. Also, the door ajar warning light and beep start as soon as you open the car door to get in.
I'm thinking from what I've read that my 12v battery has died/is dying. I'm the original owner, bought car in March 2006, and it has just under 61,000 miles on 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 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 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.

We just replaced the Traction battery in my 2004 prius. The car has 242,000 miles on it and was running fine when we pulled it in. The battery was purchased used from a 2005 prius with just over 80k on the clock. The replacement battery was removed from the wrecked prius less than a month ago.
The problem is that after installing the new traction battery, every thing looks great except the Ready light will not come on. There are no warning lights except the little red light that indicates there is no key in the car. The key will remotely lock and unlock the car so I'm sure the battery is not dead and the no-key light stays on even if I insert the key into the key slot on the dash. The shifter will only move from Park to Neutral.
What am I doing wrong? Is there some special procedure to go through to make the car recognize the key after replacing the battery?

We recently purchased a used 2006 Prius. The vehicle has approximately 74K on it now. Well the other day my wife went to leave work and pressed the power button while pressing the brake pedal, and the Master Warning Light and brake warning light both came on. The car would not allow her to shift the car so she tried to turn it off and it wouldn't do that either. After about 5 minutes she finally got the car to turn off, and when she restarted the sequence everything went back to normal and she drove home fine.
We called 2 dealers and they both seem to be confused by the symptoms, but one thought that maybe the battery was old on the transmitter. So thinking that might make sense I replaced the battery with a new one.

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.

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.

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

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.

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 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?
