Antenna: Description and Operation

The power antenna is used on the premium systems only. Battery feed for the antenna is provided from two different circuits.

One is the M1 circuit. 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.

The other circuit is the X6O from the power amplifier. This circuit is HOT when the radio is in the ON position. Ground for the antenna is a case ground.
