Code U1454 Chrysler Description

When the Radio Frequency Hub (RF Hub) is awake, it sends a 12-volt reference signal on the Transmission (TRS) Park Signal circuit. When that circuit is grounded or ungrounded by the shifter, transmission module, or brake shift interlock solenoid (depending on the model) the RF-Hub broadcasts the hard wired park position message on the Controller Area Network (CAN) Bus. This Diagnostic Trouble Code (DTC) will set when the vehicle speed received over the CAN Bus indicates that the vehicle is moving but the hardware gated park input indicates that the vehicle is in park.
