Original battery died after 5 years service. I replaced battery but discover that certain electronics don't function correctly. Windows and door locks are messed up. Driver control won't operate front passenger window; but rears are OK. Driver door lost "one touch up/down" function. Door locks are sketchy. Question: is there some re-booting or re-programing needed that I can do? Dealer only item?
View 9 RepliesLast week Wed my vehicle was not starting. Some lights would start to come on and then die out. I read the forums here and replaced the traditional battery. Perfect, started right up and no issues. Today, went to bring the kids to school and it did not start up. No messages, a few lights like before and it went dark. Is this an engine issue. I have not tried to jump the new battery yet as it is pulled forward in my garage. (Today being Tuesday and not even a week into my new battery). I looked around, nothing was left on so what is happening. It has just short of 80,000 miles on it.
View 2 RepliesI believe my GX470, 03 model, use to unlock the drivers door automatically when I removed the key from the ignition. Now that the battery has been replaced the doors no longer unlock when removing the key. Is there a way to reprogram this?
View 3 RepliesI have an '07 ES350. I was riding my motorcycle today and the key to my Lexus fell out of my pocket at 140mph. I recovered it to find that it popped semi-open. The key battery had become loose and damaged. The microchip looks just fine, as well as the key fob itself. I replaced the key battery and the key was not detected by the car. I used the procedure to start the car by holding the fob up close to the start button. It worked just fine, but the key fob will no longer lock and unlock the car.
View 2 RepliesI recently replaced the battery for my 2007 Lexus GS 350 and the AC stopped working. The AC button on the panel says "check air conditioner connection. The Audio button also says Audio off, although the ML is working, but It also doesn't show the channel.
I have checked the fuses and they seem to be ok. I purchased this car used under a year ago and everything was working fine until battery change.
The only modification previous owner has made is an iSimple to listen and o iPod from the car stereo. I have seen others on this forum having same symptoms when newly installed iSimple. Removing iSimple fixed their problem.
After installing new battery, I have no functioning air conditioning or heating system. When I select the climate button I get a message (check connection to air condition). What is going on?
View 2 RepliesMy A/c has been on the fritz for a while, and I've just been dealing with sweating in the Florida summer until I had the money to get it fixed. Now this morning I start my car after getting gas, and it throws the dreaded POA80. My fiance's 2004 HV pack just went bad about a month ago, but her's has 236k miles on it. My 2005 is only at 98k. I haven't heard my HV fan kick on in the back seat at all, but it does seem to be having a hard time charging. Is there anyway the dealer is going to try to say that me not getting my A/C fixed is the cause of my faulty HV battery? Is there any way that that is the cause of the pack going bad??
View 4 RepliesAfter weeks of receiving an alert about my battery being low on my key fob I finally replaced the battery. But the drivers side door won't lock. The car does start, and even after you put it in reverse the doors still won't lock.
View 2 RepliesI let the Prius sit for 3 days over the long weekend, and on Monday it would not start. Got a big red triangle exclamation mark on the dash. Figured it was the 12V battery going, so I replaced it with the Optima Yellowtop. Took it all apart, put it back together. Charged the yellowtop using a Schumacher automatic battery charger made for AGM batteries. Run fine around the block, so I figured it was good.
My wife took the car to work this morning. Said the ride in was just fine. Locked it and went into work. When she came out at break, it wouldn't open. Completely dead. I walked her through using the metal key to open the door, and she says it is all dark, nothing happens when she pushes the start button. We have the SKS, of course.
It drove fine for about 3 weeks, and then one day when I went to start the car, it acted like the battery was going bad. This didn't make any sense to me, because the battery had just been replaced a few months before I bought it. It was a weekend, and the car seemed fine otherwise, so I figured I'd just take it to a mechanic on Monday.The next day I drove it to the grocery store, and when I went to start it nothing happened. The electronics came on, but it wouldn't start. No cranking, no clicking, nothing. I finally got it to start by pumping the gas while turning the key. However, even after I got it to start, everything electronic in the car would shut off and then come back on again randomly, and the car would try to stall out every time I came to a stop if the electricity happened to be off. After getting it home, I couldn't get it to start again at all. I didn't sell my trusty old '97 Toyota Tercel. I have driven it across the country and back four times, it has 281,000 miles on it, and it has never given me any problems. That's what I've been driving since all of this started.
And I got the Civic to replace the Tercel. Now I'm thinking I might just get rid of the new car and keep the old one! Haha!I couldn't afford to have the Civic towed to a mechanic, so I had my mechanic friend come and look at it several weeks later. The first thing he thought it could be was the battery, so we went and had the battery tested. Sure enough, the battery was bad, so we took it to wal-mart (where the battery came from) and they replaced it with a new one.Fast forward to three weeks later: all of a sudden I'm having the same problem I had before. Slow to start this morning, and then this afternoon I'm driving down the highway and BOOM everything electronic SHUTS OFF, all gauges drop down to zero, and I feel the car lose a little power. It still drove because it was running on the alternator, but the electronics kept shutting off and coming back on again. It got to a point where about every other second it would blink on and then off again. When I got the car home, I shut it off, switched cars and continued about my business (all of this happened while I was taking a car full of kids to their parents). When I went to start the Civic after getting home, all of the lights came on but the car would not start.I don't know what to do.
Purchased an 04 Prius with 140k miles and bad HV battery. Used torque app and pulled original codes for bad HV battery. I was able to drive/limp the car home for tear down and replacement. After installing a used HV battery that had 80k from and 08 car. It will start but shutdown after a few seconds. I was able to put it in to drive and move it but it still dies. Energy display shows no battery status and now I get the connect to air conditioner communication warning. The battery's are reading 15.2 volts each from the torque app these are read in pairs so seeing 14 readings all within .1v of each other. I am not getting any codes from the computer.
View 19 RepliesI 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 Replies2005 Prius I picked up a few weeks ago decided to eat both of it's batteries for lunch and leave me high and dry. I replaced the aux battery yesterday which I was lucky to get at cost at the toyota dealer since the aux battery was original. Put it in and all was well with the car for the rest of the day. Got in it today and headed out and was welcomed with the big stupid "!" triangle, the regen brake warning, check engine light, "PROBLEM" written on the display with a picture of a "!" inside a car outline, and some severely reduced performance. So I looked online and found a place with a bunch of low mileage batteries out of smashed up 2009's.
View 19 RepliesMy car started giving me trouble I ran the scan tool and it told me that cell 6 was bad on my battery. I replaced the cell and put the battery back in now the check engine light is on and the problem triangle is on and the car wont start and only shifts into neutral but when I check for codes i get nothing .
View 6 RepliesI have a 2008 Prius, MFD died one day, screen completely dark and all buttons on it are unresponsive. I used a voltmeter to check the 12v battery which had troubles last winter (had to jump it once) and it was at about 10.6v so I just replaced it with an Optima battery. Sadly the MFD is still blank.
The MFD actually came on for a second a couple weeks ago which led me to believe it was still functional and just not getting enough power from a failing 12v.
I have a recently purchased 2005 Prius- Mileage-150.3k having several lights on the dash: ABS/VSC/Engine Check/ Brakes, etc. See attached screen shot. Initially, I got into the shop and had the codes read out several codes. In all, I was informed the root cause was a bad 12v and bad hybrid batteries. By this time , the car was still moving, though not very smoothly. however, less than a week thereafter, the car couldn't start again.
We decided to replace the 12v first, hoping to get it back to start but it wouldn't. I've checked the fuses in the engine compartment as well as on the steering column- all okay. I've checked battery voltage, it's now at 12.3v. When I try to start, the Ready light would simply flash for 2-3 seconds before going off. I've rechecked battery connections as well as the brake controls by the 12v battery- all well tightened.
I've attached some pictures of what it looks like. Sometimes there are no lines and just black but the display button still overlaps. Everything else seems to be working. I think this happened when I got the 12v battery replaced. I am also not sure I have a nav dvd. How do you eject those DVDs?
View 2 RepliesI purchased a 2005 Prius with 54k miles with a rebuilt title July 2011. About a month after I purchased it (from a private seller) I started to hear a slight grinding noise. It turned out it was the transmission/transaxle. I drove it for about 4 more months since I knew I had to replace the trans anyway. Next, I sourced a used transmission from the guy I purchased the car from. I installed the trans myself. But, it wouldn't run right at all afterward... it wouldn't go over 5mph and it would jerk. I took it to a Toyota shop and was told that it now had a dead 12v battery and HV battery.
I had both replaced. It still had the same issue with drivability. I took it to the dealership for a proper diagnosis and was told the transmission was the issue. So, I purchased another used transmission and installed it. I was very careful to make sure everything was installed correctly. So, now the car won't drive at all or even go into park. Attached is a picture of the current screen, which says "The transmission 'P' lock mechanism is abnormal. Park your car at a flat place and apply the parking brake completely." So, did I get another bad transaxle?
As I see it - my choices are
1) put in another used transmission, which I could do (3rd time is a charm) ,
2) spend more money to diagnose the car again or
3) sell it as is and get nothing for the car
I took my 2005 Prius to dealer and was told both battery computer and battery CPU were bad (easy $4,000.00 fix). So, I pulled big battery, located bad cell and replaced with similar voltage (7.9 VDC used cell). After re installing, the car will only go to neutral and will not start. Note, before tear down, car would start and run (I drove home from dealer). Before pulling big battery I could reset trouble lights for short time by removing ground to AUX 12V battery. Now, lights don't change and are always on. Car will not start or run and will only go in "Park" and "Neutral" and "B" does not show on dash like usual.
View 19 RepliesI have a 2007 Prius. We left for vacation for 2 weeks. Came home. Started the car and then all the lights came home. I thought the battery must have drained. But the lights are all on with a new battery. Is there a way to clear all these?
View 8 Replieslast week I got a whole array of warning lights, including the triangle of death. Took it in to my local mechanic who diagnosed it and told me it was the HV Battery. So, as a temporary fix, we did some DIY and just replaced the bad cell. Everything went well, just some minor troubles toward the end with the engine not turning on, which we fixed by switching the orange switch on the battery and disconnecting and then reconnecting the 12V battery. It was driving great, until u got to work this morning and all the lights came on again. What am I missing?
