LIMP MODE

Its most def some of the battery modules have gone bad. Unfortunately with these hybrid cars, swapping out battery modules with used ones is only considered a “temporary fix”. Once another battery module gets weak and throws the pack out of balance, the entire car will eventually go back into another limp mode or worse, come to a complete halt. If you plan on driving these cars for another 10+ years, you are better off saving up a few thousand dollars for a brand new replacement pack. Used batteries aren’t going to last as long as new batteries. Its an endless cycle of pulling the service plug, unbolting the battery pack, taking it all apart, then spending a week or two balancing each 28 cell modules going from 3–4 deep cycles with a charger/discharger. Its painful tedious job to make it a driviable machine. The cheap temporary solution is perfectly fine if you don't plan on keeping these cars long.

 

I build a lot of late model 3rd gen retrofits and put a 3 year warranty on them. They are less money than a new one. Given that a new one will likely last 8 to 10 years, you only get a 1 year warranty unless you pay the dealership a huge amount of labor to get a 3 year warranty. Feel free to call me if you'd like. I'm only 3 or 4 hours away, and all work is guaranteed. I'll even check your maintenance items and I usually have most of those parts with me as well.

 

With a NEW battery, the warranty doesn't really matter. It could be a 1 month warranty, and it will still outlast any other used pack.

 

sounds like a plan, they do a great job!

You're around 3.5 hours from Olathe. Olathe Toyota sells a new OEM battery for ~$1,600. That's the lowest that I've seen reported on this site. There is a core charge (as with any new OEM battery purchase) and they are currently on back order. (There's inconsistency over whether you can carry out for that price without installation. If you call, report back what they tell you.)

Remember, those packs are not fully assembled.
Buy or rent an inch-pound torque wrench. I just had a customer who did not tighten things properly. Not we are chasing down problems related to arcing. No fun.

 

what the warranty?

 

This just means the car is not in bright sunlight, so, as long this is the case, it is nothing about which to worry.

These are really just further codes that corroborate the other three (P0A80, P3021,P3022).
A new battery should see you with no codes. Let us know how it goes with the rebuilt form Jessica. It is always good to have information on how well they last.

 

One word of caution (maybe 2):

• The sheet metal edges are sharp and will easily slice so wear appropriate safety gear
• The pack is awkward

There are many YouTube videos on how to remove and replace (most do it from the back hatch).

Good luck and keep us posted .

 

I laid a small pice of plywood over the spare tire and the various wires and cables. That made it a fairly simple matter to slide the battery out the back.

Getting it started necessitated getting all the way in the back so I didn't strain my back by reaching too far. Once you get it all the way to the rear, it's not hard if you have normal health to lift it out. I think it's around 85 pounds. I wore leather gloves and got it started by just sliding one side for a few inches and then the other, working it a little at a time untill I got to where I could reach it standing on the ground.

Before you pick it up, test the places you want to grab for lifting to make sure they won't bend. I don't remember exactly where I held on, but it did take a little experimentation before I decided on the best lifting points.

If you have someone to help you, that may make it easier, but I'm used to lifting heavy stuff, so I felt more confident doing it myself.

 

Good idea.
