Battery Cell replacement

Those lights on your dashboard store error codes to guide you via an OBD2 reader and phone app or Toyota Techstream on an old Windows computer with Mini VCI dongle...

The symptoms you describe are nothing more than the car's computers shutting off the electric motor and its systems to protect you from damaging your car.

If you have a phone app like Dr. Prius or Car Scanner App you can clear these codes and get the hybrid systems running again. Same with Toyota Techstream.

And I or we can walk you through battery rebuilding, but if you want a new car-like upgrade, don't bother with module swapping and enjoy a way better brand new car with a lithium pack: https://projectlithium.com/?ref=9qLPw

how did you know which cell was bad?

 

No mention of whether any warning lights illuminated or if codes were read?

That's a heck of a jump to make, going from suddenly slows down and no matter how much I press on the gas it won’t go above 5-10 mph to digging into the HV battery without a code.

Anyway, assuming you did have codes read, and did a good job building the battery, the first thing I would check (based on your symptoms of my car will turn on but the engine won’t start) would be whether the safety disconnect was installed properly using all three steps. Insert, rotate handle upward, slide handle downward to engage interlock.

 

Absolutely HATE the seemingly new requirement to double post everything. No matter how long I wait after the first click, nothing will post. Click it again and BANG, instant double post. Then, in order to not have a double post, I edit the duplicate to be different. For instance, I changed this post from a duplicate of the above post, into a b...itch session about duplicate posts!

 

@TMR-JWAP after noticing a ton of double triple and even quad posts I figured I'd post here what works for me. easy way to reduce double posting | PriusChat
A few others have routines they use to reduce doubles..
The new 'priuschat behavior' is sure different than it used to be when clicking post and the post was not visible within a few seconds.

 

Try refreshing the thread in a different tab to confirm it posted before hitting post reply button again... That's what I do, but sometimes the server doesn't refresh the new post even though it posted. If Danny ever finds a spare minute from his primary IT job and he completes the server migration these problems will go away. But for now I think we exist on a really old server in his mom's basement.

 

What codes are you getting?

 

First time I disconnected the HV battery for a repair elsewhere I was thrown by the funky way the orange safety plug snapped back in. Did you get that part in correctly?
