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.
View 3 RepliesWhen I start the car and get the Ready light, I try to shift into P or R, or anything, it doesn't shift. Then it beeps once. I've tried turning everything off. Exiting, locking, unlocking and retrying.
I get the Ready light and the gas engine even starts, it just won't shift. But beeps once after I try to shift into any gear.
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).
View 16 RepliesI 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.
View 12 RepliesMy 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?
View 19 RepliesWhen 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 ...
View 6 RepliesI am still getting used to my new Prius, just have a little over 700 miles on it. I recently noticed something very strange with the car - if I am in "Ready" with ICE off, and I put it in drive and release the brakes, but do not press the accelerator, the car will slowly move forward, just like a regular auto transmission. After about 1 second the speed will reach about 2 mph and I can feel a very small rumble in the cabin and a very light vibration on the steering wheel. It sounds like a very low frequency bass, and it lasts for less than a second.
It goes away and the car continues to accelerate up to about 5mph (the accelerator is still not pressed). This sound is almost unnoticeable, and it does not happen if I release the brake and immediately press the accelerator, it only happens while creeping forward very slowly. I was able to make this sound/vibration last longer by "riding" the breaks and keeping the speed around 1-2 mph, it is very faint and I have really listen to it. To me I believe it is caused by some resonance/harmonics in MG2 turning at extremely low RPM, at least it "feels" somewhat "electric"...
The few times I monitored the 12V charging voltage with ScanGauge during driving it has been very stable at 14.0 ~ 14.1V for almost one hour worth of commuting time. Someone from another board commented that his charging voltage varies up and down and he suspects the charging voltage adjusts itself depending on the 12V battery SOC, and thus my battery may be so weak to require continuous charging at 14V.
View 16 RepliesI used to fill up with gas without shutting the car down, because I didn't see a need for it. I would disable the fan on the climate control every time to avoid having the ice come on as I refueled. I figured that because the ice wasn't coming on, I wasn't breaking the law. I've since changed my mind about this, after reading posts here on Prius Chat. I also recently noticed on the last few fillups that it seems like the gas capacity on the bladder has decreased significantly.
I used to be able to refuel the car when it was down to a single flashing pip and put 10.5 gallons in with no problem, and without overfilling. I have always been careful not to overfill. However, it seems like now I can get only 8 gallons in at the most. The capacity has decreased with the colder weather, however I used to be able to get 10 gallons in on a consistent basis without overfilling even during the winter.
Is this reduced bladder capacity a result of damage to the system, or is this normal? I have probably filled the car up about 100 times since I've owned it (odometer is around 50K now) while remaining in the ready mode.
Is there anything I can do to expand the capacity of the bladder back to normal, or will I have to live with this? Although it's annoying, I'm not going to spend the money to replace the fuel tank unless it's truly necessary.
I have a 2007 base model and for the last two months I keep getting three beeps and on the mfd shows up "Cannot Change to EV Mode Now". I haven't done any mods to the car. It seems to happen during the first couple of miles after start up, but it also happens when I need a little extra power to pass a car on the highway or if I've been coasting for a few seconds and then hit the accelerator again. I live in Atlanta and the temps have been 60-80 degrees for the last few months, so it's not getting to hot / cold.
This might be a coincidence, but it seemed to have started doing this after my last emissions test. The gentleman who did the test acted like he had never seen a prius before and took him a good 10 minutes to hook up his equipment. As this is going on, he proceeds to touch all kind of buttons on the MFD and got to screens I have never seen before. It wasn't until a younger co-worker came over and showed him how to hook it up that he stopped messing with buttons. My question is, could he have done anything on the screen that would cause the issues I'm having.
My Prius IV with about 10K miles started to emit a high-pitched electrical humming sound under the hood when it was in Ready mode. It did not have this sound before. I opened the hood and found the sound was coming from somewhere around/under the engine area. I want to know if this is normal on Gen 3 Prius? I have seen post on the same noise in Gen 2 Prius but the posts (thread) stopped without a resolution.
View 19 RepliesHeading out on 4 week 3k mile road trip. Have 12v adaptors for a very efficient laptop and smartphone.
It seems that in "Accessory" mode the PIP is using only the dinky 12V battery so this is not a healthy solution. Is there a recommended strategy to put the car in semi-ready mode and reduce all possible drain so that utilizing the 12V will not be draining the traction battery reserves much at all?
I'm thinking that perhaps trying to put the car in "ready" mode with the FOOT OFF the brake indeed fires up access to the traction battery without firing up other things that require the full power monty that Ready mode with the FOOT ON the brake requires. Seems to me the PIP is a great mobile office solution if we could gain access to traction battery reserves without running much else.
When turn on the start on my car the engine kicks in, how come the Ev mode doesn't turn on the I select it?
View 13 RepliesI've had my nice new red Prius now for 2 1/2 weeks now, and I'm noticing a disturbing trend. Other drivers don't seem to see me! I'm not taking about drivers who don't look while changing lanes. I've now had 4 separate incidents where people have turned left RIGHT IN FRONT OF ME, causing me to slam on my brakes.
Now, prior to my Prius, I had a gray Matrix for 7 years. I would think the gray Matrix would have blended in more than the red Prius would have, but I don't think in the 7 years I had the car, I've had this many of this kind of close calls I've had in the past couple of weeks.
I have clearly noticed that in PWR mode, apart from the obvious change in gas pedal response, the ICE tends not to shut down and burn fuel when releasing completely the gas pedal, especially - but no exclusively - at higher speeds (e.g. >90km/h).
In normal or ECO mode the ICE will turn off (though still turning, I know, if at "high speeds") and fuel consumption will show 0L/100km.
With PWR the engine spins and you see a fuel consumption not equal to 0.
My theory is that the engine management will be a bit more aggressive and tend to keep the ICE spinning with gas to make sure that when the gas pedal is pressed the reaction is immediate and there is no lag due to the MG1 spinning it first to turn it on. Moreover, the battery is charged more than just letting the wheels spin, but less than braking, in this way, since the engine can actively drive MG1 to generate energy for the battery (not very efficient, but after all this is PWR mode... ).
This would justify,BTW, in a more scientific way the statement on the User's Manual that says that PWR mode will tend to increase fuel consumption.
It happens yesterday when I passed an accident caused traffic jam. The day is hot, about 100 F and the traffic is very slow. It lasted for about 15 to 20 minutes, of course the battery had only 2 bar left. After the traffic jam, the battery is charge quickly, but I realized that the EV will not turn on, or the car has only gas engine running. I can feel the acceleration is different with only gas engine running, not as smooth as normal. I got home, turned off my car. After two hours, I tried to drive it again, it's still the same. Until this morning, it got back to normal. During the whole time, there's no any sign showing there's any problem.
View 4 RepliesWhen I'm leaving the house and I pull out onto the street, I have to go close up a very annoying gate which takes a good few minutes to do. The car is still in it's warm up mode so the ICE is running the whole time. I know just turning it off would save gas, but would it be bad for the engine, to turn it off with the key before it shuts itself off?
View 9 RepliesI recently purchased an 05 prius pack 4, it has an Auto mode on the headlight switch that does not work. as in the headlights do not turn on in pitch black night... From the searches I have done it appears that the car should not have auto headlights and yet it has the switch... I dont think its canadian because it does not have DRLs... if some models DO have auto headlights then what would cause them to not work.
View 3 RepliesMy 2000 v6 beeps 3 times when i turn it on and flashes the word STOP! while leaving the abs light illuminated on the dash as well as the brake light. The car also feels a little shaky while slowing down if touching the brakes, and when accelerating in first gear it tends to buck slightly. Also I had a new flywheel, clutch, tranny all the works just put in last summer, is it a problem that the clutch is at the top, when i first got it back with the new tranny it was releasing at the floor.
