Gen 2 2006 HV issues (C1259, C1310, P0A80, P3022) in Phoenix

Welcome to PriusChat!!

Basically your HV battery has or is failing, and if you continue to use the vehicle it will eventually leave you stranded at best.

Find out what options you have by calling Steve Keith at PHOENIX HYBRID BATTERIES (say PriusChat still misses him)

Then clean up your HV battery fan, doesn't take that long and is fairly easy. This won't fix the problem, but is part of the overall / eventual 'fix'.

If you're a DIY type, replacing the failed module(s) isn't that difficult but requires a way to balance the battery pack afterwards, otherwise it will fail again, either sooner or later. Most here use the http://hybridautomotive.com/ products for reconditioning/balancing. There might be someone local to you that has the above gear for a group share, loan or rental. Sometimes you can find a used set offered here for under retail, but that usually gets snapped up quickly.

 

Your pack is dying. It's on life support.

Use this time where it still "kind of works" to purchase a new pack. If you don't then when things go wrong for the final time and the pack is dead, you'll be scrambling to find any solution.

 

easy fix, but you still have an old car. how many miles on her?

 

Someone opened up the HV battery pack to fix a loose washer problem? (is your HV battery possibly rebuilt or used?)

The 12v battery is in rear passenger corner, check the connections leading to and from the 12v battery for tightness (and standing water).

Then measure the 12v battery voltage with a multi-meter, as it could be failing. Do you know when it was last replaced or serviced?

How many miles per week do you drive this vehicle? If you're not using it that often the 12v may fail sooner (generally speaking).

 

new $1,600. battery. but you're still looking at other potentially large expenses

 

I looks like someone did a very poor job rebuilding that battery.

A rebuild needs to be balanced to have any chance of success. It should also get a new wiring harness if there is any sign of corrosion in the connectors and there usually is. You might be able to salvage that one by checking the wiring harness, checking the torque on all the nuts, and using a Prolong charger to rebalance the cells.

The best solution is a new battery from Toyota. Boom! Done! Some places will sell you one over the counter. Some insist on installing it themselves. Replacing the battery isn't all that hard. If the rest of the car is in good shape and you want to keep it long term, that's the way to go or get a kit of new cells from @2k1Toaster who has posted above. Rebuilds are usually just an expensive way to purchase trouble. @SFO mentioned Phoenix Hybrid Batteries. I see that they sell rebuilt and also new for $2,400 installed. That's not a bad price for a new installed one.

 

Nothing to do with the 12V. Cell 12 is the twelfth cell from the end of the HV (traction) battery. On the 2nd generation, that's counting from the ECU end of the pack, iirc.

 

That is correct it is the hybrid vehicle (HV) battery, not the 12 V battery.

It is actually block 12 which are modules 23 and 24, counting from the RHS of the battery (as viewed from the rear of the car looking forward, as all references to left and right on a car are), the side opposite the electronics. It is most likely only one of the two modules, but a lot of people like to replace both anyway.

In addition, once the battery is put back together, you will need to ensure the battery is charged to balance and ideally the battery should have a 3 cycle charge/discharge regime done. Ensure all nuts on the bus bar are tightened to the correct torque using an in/lb torque wrench which will make sure that they are not too tight nor too loose. Either situation could cause bad things, and more problems.

As you are a lyft/uber driver, time is money, I'd say forget DIY and get along to Steve Keith at Phoenix Hybrid Batteries. He is a good and knowledgable guy who will be able to advise you in a no nonsense way about the best way for you to proceed. And the repair work is all tax deductible, right?

 

It appears that you're using the vehicle enough to keep the 12v battery charged, even with any excessive 12v accessory usage.

If your no power/no start condition persists, and after checking the 12v battery connections and properly assessing the 12v battery health (try an actual voltage meter), you might consider purchasing a new 12v for this 'new to you' vehicle.

 

You get shocked when you touch the door? HV leak???

 

Sections of your battery are failing. Since the car came with a failing pack (refurbished) and it was put together wrong, you will likely continue to have ongoing problems with it.

To fix yourself, quickest way is to replace the hybrid battery with one from Toyota. It would take you maybe 1/2 a day or so for the job.

It likely retails at about $2,100 or so from the Toyota parts department. Once you do this, you will not have to think about your battery for years to come.

As others have said, you could contact Steve at Phoenix Hybrid. He has other options and can even do the work if you want. For example he installs Toyota Battery with NEW cells for $2400

If you choose to keeping picking away at your pack and just replacing sections of the battery as they fail, it will take you most of a day to do the job each time.

With this method it may only cost you $100 each time, but every time you replace a section you are introducing more variability into your pack. Which will increase the likelihood of having more failures.

You could mask some of the variability by frequently balancing your pack, but you'd need to buy $600-800 of equipment for that. Plus each balance sessions takes a few days to do properly.
