2019 Nissan Titan XD 5.0 Cummins Did I kill my ECM?

[Colozzus]

Hey all,

Just grabbed a used Titan XD. Went to pull the factory calibration/file to start tinkering with, but after starting the read and about 1-2 minutes in I got a "Timed out" error in VCM editor, and consequently the truck now has "4WD Error" and "Key System Error" on the dash. When I pull DTCs, I get U0100---ECM/PCM lost connection. Sounds like the ECM ate it in the middle of the read. Anyway to recover?
If not, anyone know what process I need to go through to replace the ECM?

Thanks!

Haul it to Nissan and put a new computer and have them reflash it. You need the Nissan security cable: or it will brick it.
