I was driving and my brake light and low pressure light came on.

Yes. I finally got it out of park. I took it to advance Auto parts and their computer showed multiple module failures. One was a auto trim line module? I was told to get it to a shop. Blinkers aren't working, high beams tailgate won't open, radio won't work. They said it's lost all communication with itself

'Full' scan test which includes ALL modules is recommended .. Just to give you a little insight .. Repair shops should have the proper equipment to do this test .. 'Professional quality' scanner will run a test on ALL modules, record and then report each systems faults in approximately 10 minutes .. That test is imperative to begin the diagnostic procedures..... Don't confuse this scan test with a simple code read from the parts stores .. It is MUCH more involved and performed by a knowledgeable technician! https://repairpal.com/repair-shops
