It reset when the rain backed off No need to turn off the ignition.

Same with mine it did reset itself. Although it wasn't raining. Weather was fine. I think something must have got stuck on front of car without me seeing it, for a second or two then blown off again. I've had it when it's been snowing though. I've not altered the CCF to the jag mode. What needs doing exactly? Do you need to alter anything else in the CCF ???
