3x in the past few weeks it has taken 10 minutes or so to start the car. the ready signal just doesn't come. All the dash lights come on too. Anyone had this problem?
You should check the status of your 12v battery. See the thread: Weird stuff happening? MPGs dropping? Test The Battery | PriusChat Don't bother having a dealer test the battery as they tend to say that the battery is still good even when it is not. JeffD
Or bad brake switch. You have the pedal depressed but the car doesn't know it. I say this assuming when you say "all the dash lights come on" you don't mean warning lights, just the normal ones.
i have same problem all dash lights on won/t go into ready mode only once in awhile that it will start and bttery says full green motor will not shut down and go in battery mode engine stys running when i do get the ready light on
i just put new 12 battery in i have 2 new ones and tried both of them and the hybrid battery is reading 222.1 volts just put 10 new cells in it and i also have another one of them i did have running the other day it charged up in the green had all but one bar drove it for approx half an hour gas motor never shut off the whole time and also when i put the new 12 volt battery in i put the pos on first and when i put the ground on the neg post i get sparks its ready 12.7 this is a 2005 prius i don't know much about it i bought it off a friends daughter she stated she took it to a dealer and they told her it need a hybird battery so i replaced 10 cells in it
i checked on hv voltage 222.3 and on the other side of it where the leads go to the front of the car i'm getting 80 and it slowly went to 140 volts and stoped cold the relays be stuck help please
there's a lot more to a hybrid battery than replacing the cells. read through some rebuilding threads and start a new thread to get more attention. all the best!
Can you provide a photo/photos of the electronic section of the hv battery? We can at least tell you if it looks to be assembled correctly. You shouldn't have any voltage on the car side of the relays until you press the power button and the main relays shut and the car goes "ready". Do you have a code reader that can display hybrid codes?
the only time i have volt on the car side is when i push the start button but it starts at 80 volts and climbs up to 150 volts very slowly and stops there at 150 volts but with the star button still pushed on the othere side i get 222.3 volts and i only here the precharge relay kick in the other 2 relays don't kick in only a couple time they hve and when they did the car started and the hv charged up in the green but the gas motor would not shut down my guess is the 2 relays on the hv battery are bad i'll try to take photos but the cover is on the cell part of the battery
Sorry if i am in the wrong discussion hello everybody , I m new on the forum, back in Europe (France) , and not much of people who knows something about working on a prius here, i am trying to solve a pbm : prius 2 ; august 2006 ; 192000 KM , used when bought , Tranny maintenance ? 12 V battery fully charged every time i try to start but used i had a HT battery failure, bill from toyota that i refused (2500 €), i change my self the 2 faulty elements (thanks you tube) and put back everything : 212 V on testing when i brought my prius 2 back home the thermic was working D & R but of course electric was not working. since then , and I checked and rechecked everything, the orange big security plug position (as mentioned by several personns) all the 3 connectors to the ECU, the connector to the Fan , even the polarity of the HT connectors .... same old song : THE READY MODE DOESN T COME ON, NO D OR R POSITION POSSIBILITY, THE THERMIC DOESN T FIRE UP , I noticed that i don't hear the Clac Clac of relays ans that the 12 V battery is drained after 1 day if stays connected. NO error CODE on ODB device i desinstalled one of the 2 main relay to try to test it, but i am stucked any ideas ? any suggestions, HEEEEEELP PLEAAASSSE thanks
