GEN 2 Backup sensor sound

[FmaxTurboSi]

mine does that when I have my cobb accessport connected and/or recently changed the tune because it resets the ECU. Sounds like it comes from the gauge cluster. I think the trucks that don't have "sync" system have the sounds from cluster all the time. Like backup, blinker and every other chime. sync equipped trucks get the sounds from the speakers.

But usually goes away after the next ignition restart cycle.

Thanks for the responses, it went back to normal on its own after a few days. Seems to be working fine for now.
