car won't shift to drive or reverse

So the thing started with lots of codes for a traction battery failure, I rebuilt the battery with nick's cells and from the display it looks like the build was successful.

Only now it won't go into drive or reverse.

Also there's a little red car with an exclamation point in the top left corner of the mpg readout screen

when I turn on the key, the power button light stays red, and even though the 12v battery was disconnected for some time, the old codes never went away.

From what I've read, I suspect the 12 volt bat might be the issue, but a jump and longer charging does nothing. With the car on battery volts drop into 11.7 with the ac running, and I thought engine would start if I turned that on, so although the fan comes on, the actual ac does not.

if it's the 12v bat, wouldn't the problems of low voltage disappear with the jump (around 13.1v)

 

Double checking the disconnect (even though the battery readings appeared normal on the display) and I don't see any way the connection could be any better.

I tried the jump directly after a fairly long disconnect from the 12v battery and the battery out of the circuit with no different results

I'm charging the battery again, just to cover all bases with it, but will be buying a new battery soon anyway.

As far as scanner codes, I have one of those cheap obd bluetooth tools, but no way to know how to use it, instructions assume you already know what you are doing, and so far I haven't much of a clue about scanners.I will likely need some sort of software and not sure what computer system would be best- linux or windows. my head is swimming with unknowns

I do plan to borrow one of those cheap bare bones scanners that a friend has, he told me it read bad hybrid battery before I did the rebuild.

 

yes, battery reinstall totally finished, although i did remove the fabric cover to check the disconnect

 

Thank you, thank you for that diagram, I didn't remember to push down, car went to ready, and shifted, going to test drive now,


thank you, thank you, thank you

 

seeing the battery level indicator gave me a false impression it was connected, evidently just enough for sensors to read voltage, but not the strong connection needed to engage the battery.

I was so sure I had done it right, I just didn't do it far enough, funny how that simple act of pushing down could make such a difference.

Thanks again.

Btw all the warnings cleared, and normal functions on a short test drive, probably take it about 50 miles later today to get an idea about mpg and actual functionality of the new modules.

 

Thanks everybody, I learned much more than how to lock the disconnect back in place. only other thing undone is figuring out if this cheap elm clone bluetooth reader can get functional. I should probably put up another post with separate subject, unless someone has a nice link that could shortcut past my confusion, hint hint.

 

Thanks for the link, looking at the circuit boards for the good ones, my pretty blue elm has like half a circuit board where the good ones have two stacked on top of each other.

I found a dr prius app in play store, so may try and see if this elm works at all, if it just reads the codes, that might be a place to start. monitoring the battery would be good, but i'm not super worried about that right now, too many other things on my mind.

Thanks again for all the information.
