The P1825 fault code refers to an issue with the Internal Mode Switch (IMS) assembly in the transmission.

This assembly is a sliding contact switch that is connected to the control valve body. It provides four inputs to the Transmission Control Module (TCM) to indicate the selected position of the transmission manual shaft.

The TCM receives a high voltage when the switch is open and a low voltage when the switch is closed to ground.

The scan tool displays the state of each input as IMS.

The P1825 code specifically indicates that the Internal Mode Switch is in an invalid range.
