Antenna: Description and Operation

OPERATION
The Power Antenna is controlled by the Power Antenna Module. Voltage is present at the Power Antenna Module at all times on circuit 54 (LG/Y). With the Ignition Switch in "ACC" or "RUN", voltage is also present at the Power Antenna Module on circuit 137 (Y/BK). The Power Antenna Module controls operation of the reversible Power Antenna Motor, according to inputs provided by the Radio on circuit 747 (O/LB), the Ignition Switch on circuit 137 (Y/BK), and the Starting System on circuit 33 (W/PK).

When the Power Antenna Module applies voltage to circuit 745 (R/PK), the Power Antenna Motor runs to extend the antenna mast. When the Module applies voltage to circuit 746 (DG/Y) current flows through the Power Antenna Motor in the opposite direction and the mast retracts.
