Backup Cams not working after battery disconnect & reconnect

[alan peterson]

Hello All... my first venture onto Ram Forum. Had to power down my 2020 2500 Cummins so I could add in a pig tail extension to the towing wiring harness. When I reconnected the batteries, no back up cameras functional at all. I'm Amazed. Did not even plug in the new harness, as it was getting late. Any ideas?

It probably has to re-boot. I disconnected my battery on my 1500 and lost the Sirius radio and GPS/satellite for a period of time. Had to wait a bit for it to come back.

I believe it could take 24 hrs for all modules to sync
