Lariat Started Hyper Flashing

Hello all, just looking for some advice. Yesterday, my '18 Lariat started hyper flashing when I use my right turn signal. Just started out of the blue, functioned perfectly one minute, hyper flash in the cluster the next.

I don't believe any of the indicators are burned out. Truck has morimoto headlights that the brow illuminates sequentially as it should, morimoto sequential mirror lights that function as they should, and OEM LED tails with BLIS that function as they should. None of the exterior lights blink faster than normal, and the BLIS system still illuminates in the side view mirror, yet the dash light is flashing twice as fast as it should.

Besides maybe pulling the negative battery terminal and leaving it off for an extended period I don't know where to start.
