The P184B fault code refers to the Internal Mode Switch 2 S Circuit having a high voltage. This fault code is related to the automatic transmission manual shift shaft position switch assembly, also known as the internal mode switch assembly.

The internal mode switch assembly contains two sliding hall-effect switch assemblies that are attached to the control valve body within the transmission. These switches indicate which position is selected by the transmission manual shaft. In this case, the fault code indicates that the S circuit of the Internal Mode Switch 2 has a high voltage.

The S circuit is one of the direction selection inputs to the hybrid powertrain control module. It’s important to note that the hybrid powertrain control module is internal to the power inverter module and is not serviced separately. To resolve this issue, the internal mode switch assembly or the circuit associated with the S input may need to be inspected and repaired.

It is recommended to consult a professional mechanic or use a TCM scan tool to diagnose and fix the problem.
