Flashing check engine light

2016 Ram 2500. I have noticed, especially when it's very cold out that the check engine light, that comes on and stays on at other times until starting, is now flashing while waiting for the grid heaters to warm up. In both cases, the light goes out after starting.

Any insight as to why this is happening?

I would start to make sure all connections are clean and tight. Otherwise, if you can scan during the CEL notice that should pin point the cause hopefully.
