DTC Descriptor
DTC B3832 08
- Window Express UP System/Function Not Initialized
Circuit Description
The express Up function of the power windows is monitored and controlled by the front and rear door modules and the individual window sensors. Each power window motor has a window sensor mounted to it. Each door module communicates with its power window sensor via the power window motor up/down command lines. The power window motors communicate with the door modules via the power window status circuit. The window sensors detect differences in the window motors electrical pulses to determine if there is an obstruction to the travel of the window glass. The power window motors will disable the express up movement of a window in the event that an object has obstructed the windows upward movement.
The power window status circuit is a unique 1-way serial data link between the door module and its power window sensor. The power window motors communicate with there associated door modules by changing the state from high to low over the power window status circuit.
Conditions for Running the DTC
* The DDM, PDM, LRDM, RRDM, and DDSA must be powered.
* DTC B1325 Battery Voltage Out of Range, must not be current.
Conditions for Setting the DTC
* DTC B3832 indicates that a sensor does not know the actual position of its window glass or there is a fault present on the power window status circuit. The sensor will send a Not Normalized/Not Initialized message over the power window status circuit to its corresponding door module.
* The door modules will attempt an express up function 5 times without receiving proper inputs from the power window motors.
Action Taken When the DTC Sets
* The DDM, PDM, LRDM, or RRDM will not allow Express UP operation of the window.
* The Express Down function will still operate.
* All other window functions for that window will still operate.
Conditions for Clearing the DTC
* The condition responsible for setting the DTC no longer exists.
* You issue a scan tool CLEAR DTCs command.
* A history DTC will clear once 40 consecutive malfunction-free ignition cycles have occurred.
Diagnostic Aids
DTC B3832 may be set and the Express Up function disabled if the vehicle or the door module has recently lost power for any reason. You should first attempt to re-initialize the Express Up function. Refer to Window Motor Programming - Express Function (Programming and Relearning) .

Circuit/System Testing
1. Ignition ON, perform the Window Motor Programming - Express Function for the inoperative window.
2. With a scan tool, clear all DTCs and operate the window within the Conditions for Running the DTC.
• If DTC B3832 resets as current, test the appropriate power window status circuit for a short to voltage, short to ground, or an open/high resistance. If the circuits tests normal, replace the appropriate window motor assembly.
