Radio Memory

CIRCUIT OPERATION
Both the base and premium systems use the M1 circuit to maintain radio memory This circuit is connected to the battery through the Power Distribution Center (PDC), and protected by a 10 Amp Ignition Off Draw (IOD) fuse located in cavity 10 of the PDC. The M1 circuit is used to supply power to the Body Control Module (BCM), Power Mirrors, and the Power Door Locks. This fuse is also used in several other circuits, for additional information on the IOD fuse. The IOD fuse is removed during vehicle shipping to prevent excessive battery draw.
