Diagnose the cause(s) of excessive key-off battery drain (parasitic draw); determine necessary action. I accomplished this by testing the parasitic draw on the Ford Expedition. I did some reserch on All Data about the specified draw with the key off. Needless to say, the parasitic draw was within spec, although we had to wait two days for thge modules to fall asleep, the draw was within spec.
