05 Prius - No Electrical Power To Dash, Doors, etc.

No, a friend who owns a title company repo'd it. He said the guy drove it in when he gave him the title loan. So sometime between the repo and the loan, the vehicle was picked up dead. It sat in a tow lot for several months. I thought it might be a fun project...I paid $500 so not a lot at stake.

 

What all do I need to run tech stream? Do I need OBD reader?

 

I will look into it. I find it helpful to add to the forum issues like this. I cannot tell you how many times forums have helped me resolve issues. I think documenting these items in the forum and having a community help out lends so much to this website and helps so many people in the future with similar issues. I have appreacited all the feedback and suggestions and they have helped me greatly. I am sure a computer software could possibly help but I doubt it will replace the experience some of the members of this forum has.

I am not asking people to GUESS...I have provided detailed information and the people that took the time to respond helped me get the interior electrical back up and running and helped isolate the fuel issues and with a little luck might help me get this car started. So while I will act on your suggestion and check out your software and use it, please note my appreciation for the skills and knowledge of the members helping me get through this.....

I would be interested to know how the software you mentioned is different from OBD2 apps. I noticed several new troubleshooting apps for Prius in the android store. Does it provide a deeper scan of the car?

I do not want to get off subject. If anyone has any other suggestions please feel free to share.

 

Thanks you...I actaully pressed the button a second time. So I will repeat the process, give it time to reset and see if we can't get the READY to appear again. Thanks guys!

 

Quick update: So I unplugged the batteries and let it sit for 10-15 min. Plugged them in and let it sit another 10-15 min. Pressed the start button and saw the READY and was able to shift into drive but nothing happened. I noticed the Break indicator light was on the entire time. There was still the big Red Trianangle. Since I was able to shift into drive, do you feel it might be the larger battery unit?

 

The battery dropped to one bar in the Main Display area. I build hot rods and flight sims so I am pretty good at both electrical and mecahnical and software.

 

No the engine did not start but it allowed me to put it into drive.

 

Is there anyway to charge the larger battery cell. I am just wondering with this thing sitting so long if it might not be dead.

 

You just answered my question...I failed to see the above the response until after I submitted the question. So at this point iI am off to checking the larger battery unit.

 

Ok so I opened the larger battery unit with the cells. I checked each cell. They all read 7.45V except for two. The last battery (closest to the orange plug side) reads 7.01v and 5 batteries down reads 6.17v Would you consider these two batteries bad and needing to be replaced? Would this stop the car from starting? Is 7.45 good for the other batteries?

Also if I purchased new cells for these two batteries, would i need to buy them with similar volt 7.45 or could I put a higher volt units in?

 

Thank you for the response. i will perform a load test as you suggested. I will take care of these two cells and atleast we can take them off the list of possible problems. Narrowing it down. Thank you and please share any other ideas.
