Won’t Turn Shut Off

Chevrolet Silverado 2019 5.3  70000 miles
Truck turns on like normal with push button. When turning off only the inside turns off leaving the engine running. The engine stays running & leaving a check engine light on. I have to disconnect the powertrain & the negative terminal to shut the engine off. I ran a diagnostic & notice that my ECM does not get the signal to “deactivate” only my BCM gets the signal to “deactivate”. I pulled the Engine Control Ignition (26 Fuse 15amps) figure out that kills the engine & removes the check engine light on my cluster. I had also removed the other two ECU under hood fuse box, but that didn’t remove the check engine light only killed the engine. If anyone knows anything or something that can help would be greatly appreciated. Feel free to contact me 469 951 09 57
