Hybrid HV Battery Issue

Hello all. Have an 06 with 200k that sat in the sun for a couple months. It then showed signs of traction battery failure with the christmas tree lights, starting up with a charge and immediately dropping to zero bars before recharging.

I disassembled the traction battery and found some corrosion and loose connections. I fixed these and the battery operated properly prior to reassembly. I replaced the cover and seats and now it won't power up to ready status. No start and no hv power for ac or anything.

Could I have missed a ground or faulted a circuit? I thought I replaced the orange connector properly as it began working correctly once I had cleaned and secured the cell terminals. Any advice?

 

I know I didn't "fix it", but after cleaning and tightening some of the terminals it would start properly and hold a charge. Some of them were arcing before I did this.

I bought the obd plug and techstream software but I can't get it to take any of the registration keys to run the program.

I'll try the connector again but was 99% sure it was resecured correctly as I had everything working properly prior to reinstalling the cover.

 

While I had all of the seats, panels and covers removed it functioned properly after cleaning corrosion from the terminals and retightinging them.

Once I replaced the battery housing, panels and seats it did not work at all.

I was able to jimmy the orange connector and its working again now.
