B3833 Buick Code - Right Front Window Express Up System/Function Not Initialized

Express Up operation of the front door power windows is monitored and controlled by the front door modules and the window sensors. Each front door window motor has a window sensor mounted to it. The Driver Door Module (DDM) and the Passenger Front Door Module (PFDM) each supply battery positive voltage and ground to power their respective window sensors. Each door module communicates with its sensor via a power window high speed serial data circuit, and a power window low speed serial data circuit. The window sensor detects differences in the window motors electrical pulses to determine if there is an obstruction to the travel of the window glass. The door modules use the information generated by the sensors to disable the Express Up movement of a window, or reverse the direction of travel, in the event that a passenger, or other obstacle, has become trapped in it.
The power window low speed serial data circuit is a unique two-way serial data link between the door module and its sensor. The actual position of the window glass, in relationship to the distance traveled by the window, is communicated via this circuit, as well as state-of-health messages and the direction in which the window is traveling.
The Diagnostic Trouble Code (DTC) B3833 indicates that a sensor does not know the actual position of its window glass and has sent a "Not Normalized/Not Initialized" message over the power window low speed serial data circuit to its corresponding door module. If the failure has occurred to the passenger side window, the PFDM detects the failure and sets the DTC.
