Assuming this is a no crank, no start? I'm not familiar with the network these use, but if you've got no communication to modules, I'd start by checking for 60ohms between can high and low at the dlc.
When you say dim, ghost voltage, where are you taking and seeing this reading?
Thank you so much for reaching out...ghost voltage was at. Number 9 pin on ignition module....trying to figure out this terminal code... check all leads changed ignition switch.. relays , fuses... no sign of damaged wire harness.... still no instrument cluster coming up. Any information would help..

Not a master but the year make and model will probably be asked for. That many codes would lead me to pcm/ecm. I would do the basic checks starting at the ASD relay checking for power from your Ecm. But don’t know the vehicle but sure the pros here will want to know. Just be patient these guys are super busy but want to help
