B3482 Description

The window switch or window switch circuits that generate this Diagnostic Trouble Code (DTC) are built-in parts of the Driver Door Switch Assembly (DDSA). There are no external circuits. The DDSA internally supplies power and ground to the contacts of each of the integral window switches. When one of the switches is operated, the switch contacts close, providing the DDSA with a specific window switch signal. The DDSA processes this signal, assigns a digital message to it, and sends the message to the appropriate Driver Door Module (DDM), Passenger Front Door Module (PDM), Left Rear Door Module (LRDM), or Right Rear Door Module (RRDM), via the class 2 serial data circuit. The door module, upon receiving the message, examines other relevant information available on the class 2 serial data line in order to determine if conditions are correct for window operation to occur. If conditions are correct, the door module applies power and ground to the associated window motor and circuits in order to move the window. If the DDSA determines that one of its built in window switches is closed for more than 15 continuous seconds, it sets the DTC.
