The Body Control Module (BCM) receives the network communication message from the Radio Frequency (RF Hub) Module indicating run operation is requested. The BCM provides a voltage output through the Run Relay Control circuit to the coil side of the RUN Relay in the Power Distribution Center (PDC) Assembly. A ground path for the RUN Relay is provided through the PDC Assembly.
