Radio Memory

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. The M1 circuit is used to supply power to the Body Control Module (BCM), Power Mirrors, and the Power Door Locks. The IOD fuse is removed during vehicle shipping to prevent excessive battery draw.
