No Juice

Gary,
I'm not sure but 179 Volts may be to low for the computer to allow the contacts to close. I don't know how you were charging the battery but if it were me I would try to get it up to no less than 200 Volts, 225 V would be ideal. Hope that helps.

Are you trying this with the car on? Is the orange disconnect switch installed correctly?

 

^^^ iow, did you slide it down after locking? ^^^

 

does the car power up?

 

201.6V is the nominal traction battery voltage and the actual voltage should be more like 220V. Probably what is happening with your car is that the traction battery ECU recognizes that the battery voltage is too low so it is sending a msg to the hybrid vehicle ECU to inhibit vehicle start.

Therefore, you need to replace the traction battery.

 

Hi Gary.

You say the car will not power up at all.. "nothing"

Even with the hv battery saftey disconnect pulled. The prius should still power up (but not ready) with lots of warning lights via the 12 volt battery alone.

I suspect you have and internal open on 12 volt battery, or blown 90amp 12 volt battery fuse located at positive battery terminal or 100 amp fuse link location driverside engine compartment..

Does headlights work on highbeams (max load) ?

If headlights work brightly then disregard my suspicions of blown main fuses.
Leave headlights on then push start/ready switch...Do the headlights remain on when trying to ready the car or do the light go out.

If the headlight go out when trying to ready the prius . then you have a 12 volt battery / connection problem..
hope this helps..

 

Hi again Gary.

I have I little more information that my be of use to you.

A prius that sits without use of 24 or so days will have a 90% discharged 12 volt battery.
At this point when someone tries to ready/start the prius the dash/console lights illuminate only half brightness.
And the 12 volt battery voltage drops to 6-8 volts instantly and the prius cannot be turned off (and it will not have ready-ed).
At this point most of 18 or so computers in the prius are locked up and loading the battery further in exhaustion/depletetion.
At this state a trickle charge will be trying to still power half the computers in the prius and will not charge the 12 volt battery..

The negitive connection at the 12 volt battery will have to be removed. to get the 12 volt battery charged.. This removal of the battery connection
will insure that the computers in the prius will reboot and reset properly the next time 12volts is applied..

You will loose fuel trim memory ( no big deal ) radio presets , and driver side power window auto up function (just lower driverside window half way. Then pull up and hold windows switch 1 second longer after window fully closes) and your back in business..

let me know how you make out ...

Ps Its nearly impossible to run down the hv battery... as the gasoline engine will always start up and recharge the hv battery..
And if the prius was not in ready mode only the 12 volt battery can be run down.. The 12 volt battery doesn't charge untill the prius is in ready mode.. when not in ready mode the 12 battery will run down quickly...

 

i leave my prius for five weeks every winter.

 

perhaps your prius plugin hybrid is different 12 volt capacity or 12 volt battery is boosted occasionaly from larger capacity hv battery/charge converter ?

Conventional prius hybrids shipped from japan to usa takes 30 days by boat. And are shipped with dome fuse removed to keep 12 volt battery from fully discharging. dome fuse removed removes half the standby load which is normally only 25-30 milliamps.
Thats .6 to .72 amps discharge daily. 18.0 - 21.6 amp hours over 30 day shipping period. This does not include the the fuel pump that cycles every 5 hours at 4 minutes per cycle all while the prius is turned off !

The last time I checked the 12 volt battery is 34-36 amp hour capacity. The op has genII some of which only have 24 amp hour battery without keyless entry.. keyless entry option gets 34 amp hour battery..

 

For Gen II the OEM non-SKS 12 V battery is 35 Ah; the OEM SKS 12 V battery is 45 Ah.

 

I think your are right Dolj..

 

Get Mini VCI so that you can retrieve the DTC yourself.
If a replacement gasoline engine is actually required, have a used engine installed, which you can buy for a low three-digit amount. It makes no sense to install a new engine for $7K when the market value of a 10-year old Prius is not worth that much.

 

i also left my '04 and '08 for unto 6 weeks at a time in mid winter in an unheated attached garage with unto 4 year old batteries with no issues. i believe the battery is rock solid until you accidentally drain it one time, then it's on the edge.
