U1433 DODGE Meaning

The Body Control Module (BCM) monitors the hardwired ignition switch input circuit from the Radio Frequency (RF) Hub module and compares it to the ignition switch status message received over the Controller Area Network (CAN) bus. The Diagnostic Trouble Code (DTC) sets when the RF Hub receives a Bussed Input message of the Ignition Switch status from the BCM. If that message does not agree with the RF Hub Ignition Switch status, this code will set. The BCM also sends an Ignition Switch "Sensor" message. If the RF Hub and the BCM do not agree on Both of those messages, the Powertrain Control Module (PCM) will not allow the engine to start.
