Yes I can only communicate with the modules 1 by 1.. jump pin a to pin b communicate with ecm only.
Each wire at the splice pack is it's own module.

Yes I jumped each wore at the splice pack g205 under dash and was able to communicate with the pcm,bcm,instrument cluster, ebcm, air bag, transfer case. But not the hvac cause I dont have automatic climate control. the snappy scanner dont have the option to check the suspension control module or the cellular phone phone..

the diagram shows all the modules have connection at the splice to the dlc. you confirmed the continuity thru the splice is open..you jumped the splice and the pcm communicates so the pcm is ok.
imo replacing the splice would be the next step.
