That lamp is driven by the DERM module. Lots of inputs and outputs that go all over the place. The DERM module could also be getting a little flaky and doing it itself. No way I could pin point a part just on the fly.
But I would start by pulling the codes and see what it says. There should be one in there that might at least point to an area to start at. If there is no code then I might “guess” the DERM might be going bad.
When you pull the codes, you are looking for codes in module “A” which is the DERM module.

might also be a ground wire with corrosion or being loose.
consider checking some of the common ground points (e.g. outer foot-well kick panels, driver-side rear bell-housing, etc).

It could be corrosion under the frame sensors mounted on the frame near the firewall on both sides. Ya gotta look hard to see em (small black square about1'' by 3'') DISCONNECT THE BATTERY when doing any work on these. Remove em take a piece of sandpaper to the bottom of em and the frame rail where they were mounted and sand em clean. Then put a coating of Dielectric Grease on the bottom of the Sensor and Frame. When you re install it use a small star washer on the bolt to help make a better ground and re install em and see if that helps. If not then you might have a bad sensor. Also peel back the carpet in the footwell area and make sure the plugs for the sensors are connected well. They will have a yellow colored cover on em. Pipe
