I have a 2008 Prius and have been thinking I should be changing the auxilliary battery soon as a preventative measure. I've changed plenty of batteries in other vehicles before but I was wondering if there's anything that's much different in these cars that I should be aware of?
View 9 RepliesI left my car for a week in the garage and the battery ran down. I had it re-charged but now even running the radio for a ten minutes with engine off runs down the 12v. The panel check says that its charge is over 12.4 v. What is going on? How do I prevent having to jump start the car every day or so even after running for 20+ miles at freeway speeds?
View 5 RepliesMy dad's 2004 Prius start despite the auxiliary battery being fully charged. No lights come up on the dash, except for the door ajar light and the blinkers when the car is locked with the key fob. Also, we cannot scan any codes because the car doesn't power on at all.
View 6 RepliesI bought a new auxiliary battery online and installed it. I reset the driver's side power window. But my CD changer now beeps four times, all the lights turn green and orange, and I cannot play a CD from the changer or eject any of the discs. Both discs currently stuck in it are store bought Third Eye Blind CDs with no stickers, labels, etc.
I'm assuming that the CD player needs to be reset. Someone in another thread mentioned unplugging the battery for 20 seconds, while someone else said I need to enter a code that I can get from the dealer. I can go without the changer but the beeping is maddening.
2005 Prius shows a C1241 code, which can mean abnormally high or low positive voltage in the auxiliary battery. In my case it appears to be abnormally high, because my voltmeter showed the battery charged to 18 volts with the car off, and when running it showed 20 volts going to the battery. There's also a POA80 code (hybrid battery pack) but I'm not convinced yet that it's a hybrid battery problem. What would cause the overcharging of the auxiliary battery?
View 8 RepliesI bought an '01 prius with more than 160,000 miles last year , until now it's been a great car , averaging 46-ish mpg , now , a couple days ago I used it to jump-start a diesel truck connecting the cables directly to the auxiliary battery , the truck started after a 2 or 3 mins, the next day the known red triangle and the red car with the (!) appeared , the dealer reads code p3009 (hv leak) but were not able to give me any subcodes. Is it possible that the computer interpreted the sudden "pull" of current from the converter (via the 12v battery) as a hv leak ?
I got the reading of the 19 modules of the traction battery and all are within 0.5 volts of each other , so I hope they are all within tolerance , and the car seems to run just fine.
I just bought a certified 2010 Prius and have had it for 3 months now. Twice within one month, there was absolutely no power to start the car because the aux battery went dead overnight. I'm pretty sure I didn't leave any lights on and don't think I did anything differently when exiting the car for those 2 times. I took it into the dealership, and they couldn't find anything wrong. They said the battery was good. What is draining the battery overnight?
View 5 RepliesJumped into the Prius this morning to discover dash lights working, no radio etc so vehicle would not turn on. Replaced the auxiliary battery (about 5 years old.) Now all dash light, radio etc are looking great BUT:
- Enngine will not engage
- Message stating Check Hybrid System
- Various waning lights on dash (yellow waning triangle, swerve icon on left)(battery, brake, chech engine, steering wheel?) and abs!!!on the right)
I left the key on and drained my auxiliary battery(It was weak before) and when I jumped it it started and then shut off after ~20 seconds. I tried various different things and all I succeeded in doing was draining my HV battery from starting it so many times. So I disassembled the pack and recharged it and now it starts and runs but it is misfiring. It throwing 4 codes:
P0300: Random/Multiple Cylinder Misfire Detected
P0302: Cylinder 2 Misfire Detected
P0304: Cylinder 4 Misfire Detected
P1305: Ignition Coil 2 Primary Feedback Circuit
I inspected the igniters and plugs and they seem to be OK and I'm not sure where to look next. I'm not sure if the battery issue is related or not but I did replace the auxiliary battery.
I have a 2005 Prius recently replaced the hybrid battery. Not so happy with it, my mpg b4 was 49-51 mpg, now I only get 40-45 mpg. I notice the car is a little weaker and the ICE rev higher everytime I accelerate.
View 5 RepliesI have an issue with Prius 2005 driver side power window constantly making clicking sound even after turning off the Prius. All other power windows works, just the driver side is having this issue. This started happening after I changed the 12V battery for my Prius.
The window still rolls down and up but it's very slow and making even louder clicking sound while rolling down and up. Also an other thing that I noticed is that windows keep going down slowly by itself after it's been closed. Any clue as to what went wrong with my driver side power window ?
I have a 2008. My car has a 12V socket in the centre console, but no auxiliary jack.
View 6 RepliesI am putting a winch on my trailer and I got an optima marine battery to run the winch. I would like to wire it into my trailer wiring so that it will charge off the truck while its running, but so that it won't draw off the truck's wiring while I'm winching... I'm worried about the size of the wire and the fuse on the factory hitch wiring. I'm probably not going to be doing any extended winching, just pulling things up on the trailer. I may just unhook it from the wiring whenever I'm winching?

View 9 RepliesI need to replace tail light assembly on 2005 Prius. Some instructions say you should disconnect negative cable on battery before doing this, then do some initialization after reconnecting the battery. Is it necessary to disconnect the battery to change out the tail light assembly? If so, what is the initialization process that must be done?
View 2 RepliesWe have a 2004 Passat 1.8 t with about 180,000 miles on it. We changed the battery and now it seems to belch out tranny fluid once it comes to a stop. I thought I read where some sensors need to be reset after a battery is changed. Would a battery change cause a leak of this type?
View 1 RepliesI just changed out the battery in a separate issue I'm having with the car being dead every time after being left overnight. After changing the battery I had a new problem. The power windows wont work from the drivers side master panel. They worked fine before I changed the battery. There are a million posts online about resetting each window and that's great except for one problem. It doesn't work.
After the battery is unhooked the window switches all blink twice with a long pause. So, I follow the procedure and put the key in the ON position and roll each window down half way (reset and tried it rolling down all the way too) and then roll it back up continuing to hold the window switch in the up position for 1 full second after the window goes all the way up(some methods online variously say to hold it up for 12 seconds or 20 seconds. I tried them all). The blinking light goes out and the auto up/down feature works as expected from that specific window but no dice from the drivers master control.
One other oddity is that the window lock doesn't function anymore. On or off, each window will continue to operate from its own switch.
I know there are battery "thingies" that plug into the lighter, which supposedly preserve the settings, but since the lighter is not "hot" when the car is not running, I don't see this working. How to do?
View 3 Replies08 RX 350. Just changed battery. New Bosch battery. Issue: After battery change, passenger windows don't work from the driver's master window switch cluster. I'm assuming this is the result of some sort of memory being wiped out during the battery change. Or perhaps a blown fuse during power up while connecting the new battery.
View 7 RepliesI tried to turn on my car this morning, but the "Ready" sign didn't go on. The whole display is black. "Check Engine" sign blinked briefly. Battery display shows the battery is "green". Everything else works - cd/radio/bluetooth, etc. As I tried to start it, the screen showed that the engine briefly charged the Prius battery, then it was all quite. I tried to wait and restart a few times, but still the display was all black and no "ready" sign. I WAS able to still move the car, but I didn't chance to drive it out of the garage. I just had it serviced (oil/fluid change). Small battery was replaced in July.
