So if you transition from throttle to brake fast enough, you will be greated with that rock hard pedal and no vacuum assist momentarily. The brake booster is a mechanical device so you can't trick it.
"Ice Mode" has something to do with the ABS computer programming in response to the wheel speed data. I believe it's a response to excessive ABS intervention so to further reduce potential lock up its reducing line pressure via the ABS pump.
