You’ve lost the PCM
It’s not responding to self/network test,and all the other modules that are,say they’ve lost communication with PCM.
Really you’d start by checking the power supplies and grounds to the PCM.
But it’s not quite so easy,the connectors are underneath an anti theft shield secured by 2 shear bolts.
Maybe start with all the fuses first,there’s a fuse box under bonnet,and the BCM / fuse box in cab is behind the panel / cup holder on drivers side of dashboard,to the right of steering column
