Help identify the problem

Welcome to PriusChat!!

Would you happen to have any scanned OBD2 codes (DTCs) that you could post here for us?

 

Check both batteries. It appears the HV battery is very weak (1 bar). Letting an old, weak battery sit unused for several days can trip codes. The pandemic shutdown has caused many packs to do this (fail).

GOOD LUCK!

 

Some will use an OBD2 bluetooth adapter with an App like Dr Prius or Torque : Hybrid battery diagnostic and repair tool for Toyota and Lexus

Others prefer the best in class for our application, which would be a "mini-vci" cable ($15) and a copy of techstream, this is the same software used by the dealer technicians to diagnose, test and repair.

 

yeah its got the turtle and one red bar the hybrid battery has died.
Start reading about hybrid battery's on this site in the technical section.

Lots of reading to do. Every G2 hybrid battery is failing including mine.

 

Maybe a Swedish member (like @DicedPixel ) can help, can't remember all of them, so you might use the search feature. Pretty sure there are shipping or forwarding services, but none off the top of my head. Many use ebay to purchase (have you tried https://www.ebay.se ), and others might use aliepress or banggood, if not in a hurry. The software is generally included one way or another, sometimes a cd, or a link, or you email and ask for it. You can find it just about anywhere online : techstream download at DuckDuckGo

A $1500 battery would last for at least 10 years ( < .50 per day). You could do the HV battery installation yourself, not hard or dangerous. You could also fix the existing HV battery pack and save some money as well, only depends on your level of commitment and down time.

Maybe you could find a decent used NiMH battery from a wrecked gen2, gen3 or gen4 (or other toyota hybrid) : http://en.bildelsbasen.se/

What vehicle with only 160,000km could you purchase for $1500?

 

... for €1500 (US$1743) you mean.

 

Hej @Chalipa, I use a Carista ODB2 adapter with the TorquePro app for diagnostics on my gen4 Prius.
But for verifying the hybrid battery's status, I would recommend the Dr.Prius/ Dr.Hybrid app with the Carista dongle.
By the looks of your video, the hybrid battery is dead
For a gen2, I would not even bother asking Toyota for a new battery in Sweden.
Would be great if you can find a working hybrid battery from a totaled gen2 prius.

so, did you end up fixing the problem? what was wrong? I have similar problem... but have to take battery cable off everytime I need to start the car otherwise it will not go Ready...

 

Read your codes. You will probably find you have a P0AA6-612.

 

Its got a high voltage ground fault code which means leaking or corrosion to ground from the hybrid battery most likely cracked leaking battery module.

Pretty common.

Hybrid battery needs to come out its going to be pretty corroded.

 

I only got the car 2 days ago with 144400klm milage, previous owner said he repaired the battery and replaced invertor (synergy drive box) and ECU, he gave me the old ecu and invertor, I put the orignal ecu back same thing.
so may be when repairing the battery something wen wrong while putting it back? I have to take it out and check i guess..

 

The previous owner probably did not need to replace the inverter or ECU.

If you have confirmed you have a P0AA6 with sub-code 612, you have one or more hybrid vehicle (HV) battery modules that are leaking electrolyte. This is causing an electrical voltage pathway from then high voltage DC to the car's body ground. Normally the hybrid vehicle battery is completely electrically isolated from the 12V system.

You need to open up the HV battery and find the leaking modules and replace them. In addition, you need to completely clean off any trace of electrolyte that has leaked on to the battery case. The case then needs to be completely dry before reassembling the case.

Having introduced well-matched (capacity and voltage) modules, you would be advised to recondition and balance the battery.

 

May be you are right because the triangle thing comes up randomly after I clear it sometimes 1 hour sometimes 2 minutes after I start driving...

But even though the car still drives with full power and battery showing charging very normal goes to full bars up and down as usual... Very strange...

 

With this code that is exactly what happens in a Gen 2. It is not strange at all. It is still a serious problem that should be addressed sooner rather than later. It does have the potential to be very dangerous what with leaking high voltage DC and all.

 

I will find the time and open the battery pack, I have to take off all the panels what a pain... I need to do it safely for sure too.
