- The Radio Frequency Hub (RF Hub) receives a Bussed Input message of the Ignition Switch status from the Body Control Module (BCM). If that message does not agree with the RF Hub Ignition Switch status, this code will set. The Radio Frequency Hub (RF HUB) also sends an Ignition Switch "Sensor" message (hard wired Ignition Run/Start circuit). If the RF Hub and the BCM do not agree on both of those messages, the BCM will not allow the engine to start.
