2022 Power Wagon First Issue (Electrical?)

[JamesEvan]

Issue: Random right turn signal failure notification while braking (Soft/Hard) followed by fast flash of right turn signal indicator upon signaling.

Confirmed both turn signals function and all brake lights function (incl 3rd). I did wash it yesterday, maybe a loose connection or bare wire? Have an appt on Monday to get it checked out and will follow up once RCA is complete.

First rule of CEL/weird issue club is check all PDC fuses (push in) and underhood grounds. This should include relays in the PDC as well.

Sounds more like a localized issue to that turn signal.

Service believes its a connection in the tail light assembly, replacing it all.

Fast flash can be caused by a bad ground which could be in the assembly.
