New thoughts on "Ice Mode" & possible solution?

I had this thought shortly after I first experienced ice mode. Hooked up an external vacuum canister, did not help.

Interesting...
Where did you connect the vacuum canister to and did you happen to measure/view the brake booster pressure or sensor voltage?
(I assumed you didn't, but wanted to verify)

I'm going to go for a short test drive and data log the throttle position, MAP and brake booster voltage while driving around under different engine loads.

AND with the engine off/ignition on to see how quickly the pressure in the brake booster changes.

The rate of vacuum drop (pressure increase) may be helpful to troubleshoot this issue. -OR- it may not be helpful at all... You don't know until you look
