Circuit/System Description

The vehicle is equipped with power windows controlled by door modules. The passenger door window can be operated either the driver master control built into the driver window switch or from the power window switch.

When the driver door module (DDM) receives a driver window switch request from the driver window switch, the DDM examines the request and checks for messages from other vehicle control modules prohibiting the window movement. If no prohibitive messages have been received, the DDM will apply power and ground to the driver door window motor to move the window as requested.

When the passenger door module (PDM) receives a window switch request from either the driver window switch or the passenger window switch, the PDM will examine the request and check for messages from other vehicle control modules prohibiting the window movement. If no prohibitive messages have been received, the door module will apply power and ground to its associated window motor to move the window as requested.
