howdy forum, got a little issue poping up every now and then

in the snow storm, my ABS kicked in, and then my brake and ABS lights turned on and wouldn't turn off....now the lights have turned off, but do come back on every now and then.....the parking brake is not pulled up and the abs still works, even though the light is on.....what could this be?

Need to get the ABS codes to narrow down the problem, otherwise you are just shooting in the dark
