Safety issue, need help

[Scap]

Agree, but why would the truck run fine yesterday after the repair and all of a sudden not work today?

No idea. But it sounds like it could be related to the work they just performed.

No idea. But it sounds like it could be related to the work they just performed.

Tech at dealer said to remove both battery terminals and connect them together for 3 seconds to hard reset the rf hub, then reconnect. Set up an appointment to take it back in, but twice now it has lost communication. When I open the door the alarm goes off and can not start it. After multiple attempts at the techs procedure the truck finally starts.

Question: is there another module or issue that if faulty may be causing the rf-hub to not respond? I don’t have a scanner, but am looking for education. Lost all faith in service depts. at this point and want to make sure I have some ammo when I go back in to avoid an expensive needle in haystack scenario. This went from a parasitic drain (which resolved) but now the truck doesn’t respond.
