Update Failed, Error Code: -4

[rpr]

I’ve received the above Update Failed, Error Code: -4 three or four times over the past 2 weeks while driving.

I’m assuming it’s a UConnect Update but the error screen does not specify that. All it says is that:

“An error occurred during the update procedure”

Any suggestions or workarounds to force this update to take?

Disconnect the batteries. Push the brake and horn inside the truck. Reconnect the batteries big one first and see if that clears the hangup and allows the update to go through. That's what I would try.
