ziggie Posted December 18, 2011 Report Share Posted December 18, 2011 2003 CTS: Where is it and/or how to test it if I can find it? Link to comment Share on other sites More sharing options...
Bruce Nunnally Posted December 18, 2011 Report Share Posted December 18, 2011 See some discussion here: http://caddyinfo.ipbhost.com/index.php?showtopic=4887 I think this sensor is the one that tells the window control exactly where the 'up' position is. You may be able to 'calibrate' it by continuing to hold the 'up' window switch after the window is all the way up. If the sensor does need replacement I assume it is inside the door.

ziggie Posted December 18, 2011 Author Report Share Posted December 18, 2011 Thanks for the quick reply; The link gets a error page ? Link to comment Share on other sites More sharing options...
Texas Jim Posted December 18, 2011 Report Share Posted December 18, 2011 The link Bruce posted works for me... You don't have to copy it and paste it... Just click on it.... http://caddyinfo.ipbhost.com/index.php?showtopic=4887 Link to comment Share on other sites More sharing options...
ziggie Posted December 18, 2011 Author Report Share Posted December 18, 2011 Sure and thanks TexasJim; I can get the link now but on post #15 (scotty) he has a "could be a solver" link that gets a ""The page you requested is no longer here. (Error 404)"" the address looks like http://www.i-car.com/errors/404.shtml. I'm trying to nail down this 'Window Position Sensor Circuit' fault code.

Bruce Nunnally Posted December 18, 2011 Report Share Posted December 18, 2011 I think this is the text of the article from i-car.com Programming the Window Sensor/Motor – Express Up Function After all repairs have been made, the driver and passenger side door window regulator motor needs to be reprogrammed in order for the Express Up feature to function properly. To program the motor, press and hold the power window switch until the window is in its fully down position, and continue to hold the switch in this position for three seconds. Then, press and hold the power window switch until the window is in its fully up position, and continue to hold the switch in this position for three seconds. The power window regulator motor is now programmed for the Express Up function. Repeat this process for each power window. Take caution: before diagnosing and/or repairing parts in or near the driver or passenger door, be sure to disconnect the appropriate power window switch. If the Express Up function is not operating properly, the window may continue to move upward very quickly without stopping, which could result in serious injury.

ziggie Posted December 18, 2011 Author Report Share Posted December 18, 2011 Well, I guess that article isn't for my 2003 CTS, it said "featured on the 2001 Cadillac Seville and the 2002 Cadillac DeVille" Besides: I tried that scenario and it fixed nothing.

Texas Jim Posted December 18, 2011 Report Share Posted December 18, 2011 DTC B3832 or B3833 Circuit Description Express Up operation of the front door power windows is monitored and controlled by the front door modules, the window sensors, and the 4 connecting circuits. 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 2-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. Conditions for Running the DTC The door modules must be powered and can not have DTC B1327 - Battery Voltage Low or DTC B1328 - Battery Voltage High set for this DTC to set. Conditions for Setting the DTC DTC B3832 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 driver side window, the DDM detects the failure and sets the DTC. If the failure has occurred to the passenger side window, the PFDM detects the failure and sets the DTC. Action Taken When the DTC Sets The DDM, or the PDM, will not allow the Express Up function for that window to operate. All other window functions for that window will still operate. Conditions for Clearing the DTC The DDM or PFDM will clear the current DTC when either the DDM, or the PDM, detects that its corresponding sensor is no longer sending the message. 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 . If DTC B3832 is accompanied by DTC U1714, utilize the DTC U1714 or U1716 diagnostic table before using this table. Refer to DTC U1714 or U1716 . If DTC B3832 is set by itself and the vehicle or door module has not recently lost battery power, it is likely that the window sensor itself has failed. Test Description The numbers below refer to the step numbers on the diagnostic table. When DTC B3832 is accompanied by DTC U1713 or DTC U1714, a failure of the window sensor battery voltage circuit, or the window sensor low reference circuit, may be the cause. This step directs you to the correct diagnostic chart where these failures are addressed. This step determines if the window is operational at all. The step does not ask the technician to attempt the Express Up movement because, when DTC B3832 is set current, the door module disables the Express Up function. This step addresses the possibility that the DTC may have been set, and Express Up disabled, because the vehicle door module has recently lost power due to a battery disconnect or other reason. Performing the window express programming procedure will eliminate this as the possible cause of the DTC. Link to comment Share on other sites More sharing options...
ziggie Posted December 19, 2011 Author Report Share Posted December 19, 2011 Thanks Texas Jim for the detailed explanation BUT; Since you know these things, what exactly would a lay-person do next in the effort to fix my issue?
