Many codes, black in battery fan wires, red triangle

This is for the fan in the back for the HV battery

 

So it looks like you need two plugs I should have them

 

It happens I have a green tech battery here that went bad and about two three something like that it may be salvageable it might be just to be balanced or see what cells are croaking and change them out I don't know what to tell you about that

 

P3000 is part of the P0A80 error code. It means you got a bad battery module, aka: too great a voltage difference between the bank of 14 blocks. Install Dr. Prius app and share some screenshots so we can help diagnose which block is bad in your battery pack.

 

The OP might have better luck researching the actual code which is P0A80.

The second character is always numeric and can only be 0, 1, 2, or 3.

 

Lol, that was a typo I fixed less than 20 seconds after I posted... You're wasting your time!

 

I don't see any edit, but ok. It still is good information for others to know what the correct code is.

 

This one works good and less than $20: https://www.ebay.com/itm/265484403768

As you drive your battery pack down the road there's certain moments of charge and discharge when the amps are just right that the voltage difference between blocks will get too high and it'll log the P3000 code. So it's an intermittent problem at first and you can go a long time just clearing the code while you drive as long as the pack doesn't start running too hot. And if you can afford it, buy one of these: https://projectlithium.com/?ref=9qLPw and it'll feel like you own a much newer Prius than you currently have.

 

Replacing the pack will save you lots of hours of diagnostics, module replacement and reconditioning. Of course that's assuming the $1500 is less valuable than the hours you spend rebuilding your pack.

 

Usually the first module that needs to be replaced is the easiest amount of effort and lasts the longest. Future modules will die more often once that part starts. But that also has to do with how good your replacement module is, as well as if your pack needs reconditioning or not.

 

P0A80 code is marketing department selling new battery packs no matter how minor the problem... P3016 is kinda like a subcode for people who'd rather repair a pack than buy a new one. You're gonna need some high quality replacement modules. This is who I get them from. Top quality every time: https://2ndlifebattery.com/product-category/toyota/

 

That is one way to look at it if you ascribe to a particular train of thought, but what P0A80 (P-zero-a-eight-zero) really means is there is a problem detected in the HV battery, more detail to follow when it becomes available.

Toyota chooses to deal with any problem with the HV battery that might occur is replacing the entire pack. Given the difficulties of doing reliable and timely module replacements, this is entirely reasonable. Toyota's focus will be to do a reliable repair that inconveniences the customer in the least possible way.

The fact that DIYers might choose to bear the brunt of inconvenience in exchange for a less expensive route is also reasonable but it doesn't make it a better approach.

 

Lol, that's the most ridiculous thing I've ever read on PriusChat... You really think warranty repair specialists are going to keep your car on the road for an affordable price to avoid you any inconvenience? What planet do you live on?

In the US and Europe we get people on here often who have a bad battery pack that shows up as a bad inverter error code and before checking to make sure it's not the battery they charge $5K for an inverter and then shrug their shoulders because it turned out the be the battery pack and expect you to double down and pay even more. That's criminal negligence as far as I'm concerned!

The P0A80 error code literally says: "Replace Hybrid Battery Pack" even when the problem is minor and takes less than 5 minutes to fix. But if you take that less than 5-minute to fix problem to the Stealership they will say it costs $3K to $4K to fix. If we had legitimate consumer protection laws it'd be a legit crime to take advantage of your obvious gullibility.

No need to reply to me either, I'm putting you on "ignore" so I don't start saying inappropriate stuff to you.
