2014 Prius c, 125k. Hybrid battery is at 68%. Here's a long story short. I left the key on on my car and it killed the 12 volt battery. I recharged the battery however I left the seat panels off. I went to my girlfriend's house today with my dog in the back seat and he still had his leash connected and somehow he managed to get it hooked on the hybrid battery release (red connector on the hybrid battery behind the passenger seat and under the rear seat)and somehow unhooked it. That threw a couple code and I was able to re-secure it with no issues. I cleared the code. On my way home I got another code DTC u0140, loss of communication with the body control module. I need help determining what's causing this. I read somewhere else that it could be an HEV fuse? If so where is it? I am currently getting a high voltage error on the HUD. It will not let me put my car in drive I do have to disconnect the high voltage battery every single time to get it to drive now.
