2004 Prius, 176k. Error Codes: P3000; P0A80; C1259; C1310

Julie,

I would get your Prius to Avi (Avi's Advanced Auto Homepage). He has been helpful to many Prius owners here on PC.

• I had heard that Hybrid Battery Repair was in bankruptcy, but that is hearsay.
• The $800 option sound low and is probably not a full rebuild, just replacing a few modules which does not generally produce a long lived repair.
• Using a low mileage salvaged battery from a 2004 to 2009 (newer is better) Prius is a good path and the price is in line with this approach. I would also spend the time to rebalance/test the modules before installation for a reliable repair.
• Using 28 modules from a 2010-2013 salvaged battery installed in your existing battery shell is a very good approach. I would again spend the time to rebalance/test the modules before installation for a reliable repair. These newer batteries are not quite compatible as a complete unit swap which is why you do the module swap.

1. I agree that the 12V and HV batteries need to be replaced. The car will probably be operational after that is done.
2. That is a decision you have to make, considering how much longer you want to drive the Prius with 176K miles. If you had to pay for the body repairs, you may want to get some return from that investment.
3. Assuming you want to keep the car for a long period of time, I would select the option that uses modules from a 2011 salvaged Prius. If you want to repair the car so that you can sell it, then the "rebuilt" battery would be sufficient. Note that the battery is not actually rebuilt, it just uses modules from salvaged battery packs and hopefully the modules have been discharged and charged to a common level.
5. How old is the 12V battery? If it is older than 3 years, I don't think it is reasonable to expect the body shop to accept responsibility for replacing it.

 

Hi Julie,
I also have an 04 Prius with the same error codes. I replaced the HV battery and the 12 V battery and the ABS relays. (fortunately I had another prius to take the good parts off of). None of those actions solved the problem and the same error codes are there.
Did you resolve your problem? Please post the results! Thanks.

 

are you sure the parts from the donor car were good?

 

Julie,

I met a battery rebuilder today that seems to really know what he's doing. I was just asking him general questions (not that I need a battery) but his responses were very genuine, not loaded with crap from people that just talk. I asked if he can install gen3 cells into my gen2 battery pack and he told me he would do it for $150 if I provided him with the gen3 cells. I thought that price was incredible!!

He normally charges $550 to "rebuild" your pack but I wasn't interested in rebuilding, just wanted to do a swap later in the future.

But if you want a cheap pack with a 1 year warranty, $550 doesn't sound too bad.

 

Yes the donor car works perfectly with no codes

 

UPDATE to a solution I eventually came across for my situation causing these codes..
I had a myriad of dash lights lit for over a year and went through quite an odyssey with multiple 'repairs' that were dead ends. Fortunately the car drove fine the entire time. I swapped out the main HV battery, 12Vbattery, cooling fan, ABS relays, and misc other parts with those from another prius. Thank goodness I had access to that other car or it would have been $10k worth of parts!
Anyway, the Red Triangle Exclamation, the VSC, and the (!) lights were all lit. Codes for the main battery, ABS, and hybrid control were activated. P3000, P0A84, B2799, and some other intermittent codes. Dealers of course kept saying the main battery was bad and wanted to replace it for thousands of dollars.
Ultimately the problem was simply a CORRODED CONNECTOR in the electrical wiring harness connector plug. In the right rear part of the car near the 12V battery and blower motor. Some members of this thread had suggested loose or corroded connections as the culprit and they were absolutely correct! Thanks! This is a relatively common problem and can throw codes that have absolutely nothing to do with item referred to in the code (like VSC). So when you get these codes, don't always assume the main battery is bad (even tho the codes indicate that) and spend the extra time tracing and inspecting/testing all the wires and connectors that you can reach when you are making these repairs. In my case it was ultimately simply a $5 repair. Since I experienced this, I have read numerous cases of others having the exact same corrosion issue in the same place. I hope this helps others in a similar situation!

 

How about a photo so that we can understand the exact location of this connector?

 

yes spme photo so that we can understand the exact location of this connector

 

Were you able to post a photo?
I think we are having the same problem.
Same codes.

Please help

 

Hi
i am new in this since i got by prius 2008 before 4 month only
today the red alert appear after i test with OBD2 Bluetooth + my Samsung Phone this code:
P0A80
P3000

please any advice to solve this problem ??

 

i forget to mention that my car had been come from Auction (salvage) from USA to Jordan -
and checked it with car fox = it was sank ( salt water ) ??

 

Those codes imply that you are likely to have 1 or more weak HV battery modules. Do a search on these discussion groups to educate yourself on options for repairing/replacing the 200v battery.

Since it’s a flood damaged car there’s a change that it’s just corrosion on battery bush bars. So check that if you take the HV-battery apart.

 

this explains why your were getting bad gas mileage

 

yesterday i tested again by Techstream and the HV show these Value :

Block 1 = 16.58
Block 2 = 16.58
Block 3 = 16.57
Block 4 = 16.52
Block 5 = 16.58
Block 6 = 16.59
Block 7 = 16.57
Block 8 = 16.55
Block 9 = 16.56
Block 10 = 16.66
Block 11 = 16.57
Block 12 = 16.50
Block 13 = 16.60
Block 14 = 16.62

and the technician told me that the problem in Block 10

 

Test the blocks under load, turn on ac to high and watch the battery drain. If you have a bad block, it'll drop real fast

 

To everyone that wants to see what a corroded connector looks like.
Here you go.

HV battery cooling fan fault and fix | PriusChat

 

I have a 3rd generation 2014 Toyota Prius and every so often the code P0A80 Hybrid Battery Replacement code keeps popping up ever so often! I have a obd2 scan tool so i reset the fault code in order for the hybrid system to function! when i perform a reset, it could be weeks till the fault code comes back up again, or it could be days! Time varies!

So I decided to scarp the hybrid battery and perform some checks on the cells! Every cell i got between 8.02 to 8.05 volts! so seemed like they were all good! then i decided to clean the links that connected the cells together and shine them up good! I also cleaned out the cooling fan for the battery!

Mounted everything up and started my car and everything was good for a while, but then it still keeps coming up!

Need help! anyone at all have suggestions based on this experience! would really appreciate some help!
