Door lock chirp malfunction

2018 TRD OR Double cab
So I had a PDR guy fix a dent in my rear pass. side door and he did a great job but unfortunately managed to severe 2/3 wires while putting a rod through the door grommet. I found the wires and soldered them back. It has been a while but I think I checked to see if they had any resting voltage and I believe they were not hot wires. No fuses blown... no fried relays. Now my truck doesn't chirp when I lock the doors and the parking lights don't flash. When unlocking them everything works correctly. Also when locking, I hear the actuators pulse a second time. All doors lock/unlock correctly, but no chirp only when locking. Dealer was a waste of time and only tell me that the computer was getting a can bus feedback. Their solution was to start part swapping to the tune of $1400, all of which would have to be ordered. My question is, has anyone had a similar malfunction and how was it resolved. I find it hard to believe the ECU is done after a couple wires were broken. It seems to me the problem would be isolated at the door lock actuator. It wouldn't bother me so much if I lost these indicators when unlocking but now I often question if I remembered to lock my doors after I walk away since there isn't any tones to remind me...
