Replaced transaxle, new issues - ICE won't start

all,
just finished with a transaxle replacement, was able to locate a replacement that had only 68k miles on it.
with things nearly finished I thought that I'd test car out before replacing windshield wiper pan and now I get P0ADD and B2775 codes.
the really strange thing is that now the ICE will not start up. put on the mini-vci and one strange issue is that I do not see any change in the position in the throttle pedal, it is always at a constant level and pressing to the floor while watching diagnostic tool shows no change.
since the car sat for a while I replaced the 12v battery with new one and same issues.
the EV battery is pretty low and I would like to charge it up - have not found any way to force the ICE to start.
anyone have any suggestions? with all the work going into replacing the transaxle I'd sure love to get this vehicle running.

yea the interlock has been reinstalled and is in locked mode

 

kinda interesting, I pulled the interlock and relocked it (a couple of times) and I keep getting the P0ADD code.
I thought that it would have changed with the interlock both out and in, but it seemed to make no difference. is'nt this code to signify that the HV battery is either connected or disconnected?

patrick,
I've seen mention of how the interlock switch locks in a downward motion, mine locks in an upward motion. could be that last year I replaced the HV battery and maybe it was slightly different.
will double check the interlock on the inverter, could have swarn that it clicked when I put the cover back on, but will check again.
thanks

yea, when you only futz with it a handfull of times in a lifetime it's easy to forget...
thanks for the head knocking.

 

the car had been sitting for the last 6months while I worked into my schedule the transaxle replacement, so that was probably why I forgot how to correctly put on HV interlock key...
pretty frustrated here. I found that the interlock under the inverter cover had a bent pin. straightened it out and rechecked all connections inside and out of the inverter.
would not start.
with a bit of frustration I took a small hammer and tapped the inverter cover right over the lock - SOB it started! even though it was good to hear the engine running, was a bit rough at first, but smoothed out.
well that was about for only 30 seconds when the engine warmed up then stopped. has not started since... no matter what still get the P0A0D code.
I even took the inverter interlock connected it to the cover, then put the cover back on. no deal - quitting for the day.

 

patrick,

trying to be extremely careful to always try to remove the HV interlock prior to doing any work in the front of the engine compartment and replace when done (this time to press DOWN the lock after flipping up the lever...)

I noticed that one side of the inverter interlock goes to chassis ground using a pitiful little wire. are you saying that that tiny wire caries upwards of 100 amps?

and that I should measure the resistance between the black and red wires of the interlock? want to be sure that I understand you correctly and that this is removeable connector that you are referring to as the interlock switch?

as always - your input to this site is greatly appreciated.

patrick,
not a problem pointing out wiring issue, just wanted to make minor correction to your post, thanks for all the help that you provide to the rest of us. wish you were closer, but with a little luck and lots of info hoping that this will end up getting my Prius back on the road.
