You are correct, idle control logic will only engage in a limited set of circumstances (no ac engaged, front defroster setting off, no rear window defroster turned on, flat ground). You could turn the setting from "auto" to a set temperature and not turn on the AC or defroster. This is why I put my CVT into neutral at every stop because if idle control logic is not engaged then you are sitting there with the belt slipping which of course increases wear.
