Good evening and welcome to JustAnswer!!!
What's going on with your Pacifica?
Sorry for the delay!!
This is a security issue if the check immobilizer is showing. What codes are setting? Can you talk with all the modules on the BUS? What's the last 8 of the VIN?
It would be very helpful if you had a WiTech as I use at the dealership.. On a CAN BUS vehicle like the Pacifica it would show a Topography screen similar to the attached screen which would help in determining a dead module on the BUS... Now is the bulkhead tight and all the connectors you disconnected? I know this issue is tough to find but we have to have somewhere to start.. Can you see if you get any codes from the SKIM module or any code from any module really because 1 bad module will set codes in the rest saying nobody can talk to it.. https://www.dropbox.com/s/xhm6oxbk6i06c4p/Screenshot%202014-07-15%2008.29.39.png?dl=0
Our WiTech does connect to the ODBII connector but it will still boot up even if 1 or 2 modues are down.. On the topograpgy it will show the modules in red.. At that point you would need to test for 12v and ground and if good then replace the module..
Being you didn't have an issues before pulling the dash, I would think you have a wiring issue or a pinched wiring harness somewhere..
