Delayed Accessory Feature
WARNING: This page is about a different car, the 2012 Ford Pickup. However, it is still accessible from the selected car via links, so may be relevant.
The accessory delay relay, located in the BCM, provides voltage for the operation of the power windows and the roof opening panel (if equipped). The accessory delay relay is active when the ignition is in the RUN or the ACC position, or when the ignition is changed from RUN or ACC to the OFF/LOCK position and the LH and RH front doors are closed.
